Abstract
The prostate is made up of 30 to 50 compound tubuloalveolar glands that are embedded in a framework of fibromuscular tissue and arranged in three concentric groups (mucosal, submucosal and main prostatic gland). The prostate consists of peripheral, central and transitional zone accounting for approximately 70%, 20% and 5% of the glandular substances. Benign prostatic hyperplasia affects the transitional zone and carcinoma of the prostate affects the peripheral zone. The glandular tissue consists of numerous acini with frequent internal papillae. Follicular epithelium is variable but predominantly columnar and either single-layered or pseudostratified. This cross sectional descriptive study was conducted in Department of Anatomy, Mymensingh Medical College, Mymensingh, Bangladesh to find out the difference in number of acini of the prostate gland of Bangladeshi people in relation to age. The present study was performed on 67 postmortem human prostate gland collected from the morgue in the Department of Forensic Medicine, Mymensingh Medical College by non random purposive sampling technique. The specimens were collected from Bangladeshi cadaver of age ranging from 10 to 80 years. All the specimens were grouped into three categories: Group A (up to 18 years), Group B (19 to 45 years) and Group C (above 45 years) according to age. Dissection was performed following standard autopsy techniques. In the present study, total 60 slides were made for histological study from both central and peripheral zone of the prostate which were examined under low power objectives. The number of the acini of the prostate gland were counted and recorded. The mean number of the acini of the prostate gland was 16.45, 43.54 and 42.45 in Group A, B and C respectively in central zone and 30.08, 51.35 and 44.16 in Group A, B and C respectively in peripheral zone of the prostate. Variance analysis shows that mean differences were highly significant between Group A & B and Group C & A and non significant between Group B & C in central zone of the prostate. Mean differences were non significant among all three groups in peripheral zone of the prostate. The number of the acini of prostate gland was increased up to certain age limit but decreased in extreme age. In statistical analysis, differences between age groups were analyzed by using students unpaired 't' test. The present study will help to increase the information pool on the number of the acini of the prostate gland of Bangladeshi people at different age group.

Abstract
Premature labor is one of the most serious health problems in the developed world. One of the main reasons for this is that no good way exists to distinguish true labor from normal pregnancy contractions. The aim of this paper is to investigate if the application of graph theory techniques to multi-electrode uterine EMG signals can improve the discrimination between pregnancy contractions and labor. To test our methods we first applied them to synthetic graphs where we detected some differences in the parameters results and changes in the graph model from pregnancy-like graphs to labor-like graphs. Then, we applied the same methods to real signals. We obtained the best differentiation between pregnancy and labor through the same parameters. Major improvements in differentiating between pregnancy and labor were obtained using a low pass windowing preprocessing step. Results show that real graphs generally became more organized when moving from pregnancy, where the graph showed random characteristics, to labor where the graph became a more small-world like graph.

Abstract
The spleen is the most frequently injured organ in the abdomen. Splenic rupture is usually precipitated by a crushing injury or severe blow. If ruptured the spleen will bleed profusely because its capsule is thin and its parenchyma is soft and pulpy. Such "spontaneous ruptures" never occur in truly normal spleen but rather than from some minor physical insult to a spleen that has been rendered fragile by an underlying condition. The most common predisposing conditions are infectious mononucleosis, malaria, typhoid fever and lymphoid neoplasms. These diverse entities can all cause rapid splenic enlargement, producing a thin, tense splenic capsule that is susceptible to rupture. Understanding of splenic capsular structure may help explain mechanical properties of the normal and diseased spleen. Histological changes are evident in advancing age along with functional capability of the human spleen. This cross sectional descriptive study was done to measure the thickness of splenic capsule to establish the difference between sexes of different age groups in Bangladeshi cadaver. The study was carried out in the department of Anatomy, Mymensingh Medical College, Mymensingh from June 2013 to July 2014. A total 30 human spleen were collected by purposive sampling technique from October 2013 to April 2014, among them 14 were male and 16 were female. The specimens were collected from Bangladeshi cadavers of age ranging from 6 months to 60 years, from autopsy laboratory of the Department of Forensic Medicine of Mymensingh Medical College. For convenience of differentiating the thickness of splenic capsule in relation to age and sex, the collected specimens were divided into three groups like Group A (upto 20 years), Group B (21 to 40 years) & Group C (41 to 60 years). Each group was again divided into male & female groups. In this study 10 slides from each age group were chosen for measuring the thickness of splenic capsule and examined under low power objective. In present study the mean capsular thickness of spleen was 107.71±8.70, 125.71±31.29 and 136.39±6.49 μm in Group A, B and C respectively. The mean difference of capsular thickness of spleen between Group A & B, Group B & C was statistically non-significant but the difference between C & A was highly significant (p<0.001). From this study it was also observed that the mean±SD thickness of splenic capsule was higher in male than that of female among the age groups but there was no significant difference between sexes. In statistical analysis, differences between age groups and sexes were calculated by using one way ANOVA test and unpaired 't' test respectively.

Abstract
Device-related infections in recipients of left ventricular assist devices (LVAD) have been recognized as a major source of morbidity and mortality. They require a high level of diagnostic effort as part of the overall burden resulting from infectious complications in LVAD recipients. We present a multi-allergic patient who was treated for persistent sterile intrathoracic abscess formation and pericardial empyema following minimally invasive LVAD implantation including use of a sheet of e-polytetrafluoroethylene (ePTFE) membrane to restore pericardial integrity. Sterile abscess formation and pericardial empyema recurred after surgical removal until the ePTFE membrane was removed, suggesting that in disposed patients, ePTFE may be related to sterile abscess formation or sterile empyema.

Abstract
Background: The extent and clinical significance of brain volume changes in different phases of multiple sclerosis (MS) is still under discussion. Objective: To determine the rate of global and compartmental brain volume changes in patients with a clinically-isolated syndrome (CIS) compared to patients with definite MS, by long-term follow-up and as a predictor of conversion to MS in a routine clinical setting. Methods: We investigated 120 patients (63 CIS and 57 MS) at baseline and after a mean follow-up period of 43 months, including detailed clinical examination and 3-Tesla magnetic resonance imaging (MRI). Our imaging analyses comprised the normalized brain volume (NBV), cortical grey matter (cGMV) and white matter (WMV) volumes using SIENA/X, the percentage of brain volume change (PBVC) using SIENA and the change in the volume of the thalami (TV) and basal ganglia (BGV). We also determined the amount and change of T2-lesion load (T2-LL). Results: At baseline, all the brain volume metrics, except cGMV, were significantly lower; and the T2-LL was significantly higher, in patients with MS rather than CIS. During the follow-up, only the PBVC was higher in MS ( p = 0.008) and this difference was driven by converters from CIS to MS. Quartiles of PBVC did not allow us to predict conversion to MS, but were associated with the degree of disability. Conclusions: PBVC is the most sensitive marker of progressing atrophy and a higher PBVC was generally associated with more active disease; however, it did not serve to predict the course of MS on an individual basis, in this study.

Abstract
AIM The aim of the study was to examine risks, implications and outcomes of coronary sinus (CS) lead extraction in patients with infections of cardiac resynchronization therapy (CRT) systems. METHODS The study included 40 (65.5 ± 11.1 years; 80% male) transvenous CS lead extraction procedures performed between 2000-2011. Nine (22.5%) patients suffered from infection and included one sepsis (11.1%), two (22.2%) of lead and valve endocarditis, and four (44.4%) cases of pocket infection. CS lead extraction in the infection subgroup was performed between 14 days and more than five years after the last CIED-related surgical procedure. RESULTS Totally 42 CS and 35 non-CS leads were extracted. Leads extracted in the infection subgroup were significantly longer in situ (49.7 ± 30.7 months) compared to the non-infection subgroup (19.2 ± 28.6 months). Extraction in infected patients required more aggressive methods and longer exposure to radiation than non-infected. Procedural success without major complications was achieved in all patients. Minor post-procedural complications occurred in four (44.4%) of the infected and one (3.2%) of the non-infected patients and were surgical-related in three cases. Overall hospitalization times were significantly longer for the infection than for the non-infection subgroup (21.4 ± 15 versus 9.6 ± 6.9 days). CONCLUSION Our results support the concept of complete CIED-system removal in CIED-associated infection, regardless of whether or not infection appears to be limited to the generator pocket site, despite risk of heart failure, patient frailty and a high level of comorbidity. An interdisciplinary approach encompassing appropriate diagnostic, procedural and safety standards allows CS lead extraction in this high-risk subpopulation to be performed with excellent outcomes and low complication rates.

Abstract
Background and objective: We explored which clinical and biochemical variables predict conversion from clinically isolated syndrome (CIS) to clinically definite multiple sclerosis (CDMS) in a large international cohort. Methods: Thirty-three centres provided serum samples from 1047 CIS cases with at least two years’ follow-up. Age, sex, clinical presentation, T2-hyperintense lesions, cerebrospinal fluid (CSF) oligoclonal bands (OCBs), CSF IgG index, CSF cell count, serum 25-hydroxyvitamin D3 (25-OH-D), cotinine and IgG titres against Epstein-Barr nuclear antigen 1 (EBNA-1) and cytomegalovirus were tested for association with risk of CDMS. Results: At median follow-up of 4.31 years, 623 CIS cases converted to CDMS. Predictors of conversion in multivariable analyses were OCB (HR = 2.18, 95% CI = 1.71–2.77, p < 0.001), number of T2 lesions (two to nine lesions vs 0/1 lesions: HR = 1.97, 95% CI = 1.52–2.55, p < 0.001; >9 lesions vs 0/1 lesions: HR = 2.74, 95% CI = 2.04–3.68, p < 0.001) and age at CIS (HR per year inversely increase = 0.98, 95% CI = 0.98–0.99, p < 0.001). Lower 25-OH-D levels were associated with CDMS in univariable analysis, but this was attenuated in the multivariable model. OCB positivity was associated with higher EBNA-1 IgG titres. Conclusions: We validated MRI lesion load, OCB and age at CIS as the strongest independent predictors of conversion to CDMS in this multicentre setting. A role for vitamin D is suggested but requires further investigation.

Abstract
Papillary muscle rupture and dysfunction can lead to complications of prolapsed atrioventricular valve and valvular regurgitation. Morphology, measurements and attachments of papillary muscles in both tricuspid and bicuspid valve gains utmost importance in cardiac surgeries and variations in the papillary muscle morphology is one of causes for myocardial infarction in recent time. Therefore, it is important to know both the normal anatomy and variations of papillary muscles. The study was carried out in the department of Anatomy, Mymensingh Medical College, Mymensingh from July 2013 to June 2014. A total 80 human hearts were collected by purposive sampling method, among them 49 were male and 31 were female. The specimens were collected from Bangladeshi cadavers of age ranging from 6 months to 60 years, from autopsy laboratory of the Department of Forensic Medicine of Mymensingh Medical College. All the specimens were grouped into three categories Group A (upto 20 years), Group B (21 to 40 years) and Group C (41 to 60 years) according to age. Dissection was performed according to standard autopsy techniques. Length of each papillary muscle was measured in both ventricles in different age groups. In present study the mean length of the anterior papillary muscles of right ventricle was higher than both the posterior and septal papillary muscles among the age groups. The mean±SD length of the anterior papillary muscle was 1.07±0.48, 1.50±0.37 and 1.60±0.25cm in Group A, B and C respectively. The mean±SD length of the posterior papillary muscle was 1.02±0.35, 1.31±0.40 and 1.37±0.34cm in Group A, B & C respectively. The mean±SD length of the septal papillary muscle in right ventricle was 0.51±0.42, 0.65±0.31 and 0.81±0.35cm in Group A, B & C respectively. It was also observed that the mean length of anterior, posterior and septal papillary muscle was increased with age. In present study the mean length of the anterior papillary muscles in left ventricle was higher than that of the posterior papillary muscle among the age groups. The mean±SD length of the anterior papillary muscle was 1.53±0.34, 2.05±0.39 and 2.01±0.25cm in Group A, B and C respectively. The mean±SD length of the posterior papillary muscle was 1.33±0.34, 1.95±0.89 and 1.81±0.76cm in Group A, B and C respectively and it was also observed that the mean length of both anterior and posterior papillary muscle was increased with age. In statistical analysis, differences between age groups were calculated by using one way ANOVA test.

Abstract
This cross sectional descriptive study was done by using nonprobability sampling technique and performed by examining 63 (sixty three) cerebellum. Out of them 40 postmortem human cerebellum collected from Bangladeshi cadavers of both sexes (male 25 and female 15) age ranging from 5 to 60 years and 23 cerebellums from caesarian section of intrauterine death cases of both sexes (male 14 and female 9) age ranging from 34 to 41 weeks of gestation. Specimens were collected from dead bodies autopsied on different dates from April' 2009 to September' 2009 at the autopsy laboratory of department of Forensic Medicine and prenatal cases from Gynaecology and Obstetrics Department of Mymensingh Medical College, Mymensingh. The collected specimens were grouped into three age groups like Group A (28 to 42 weeks of gestation), Group B (5 to 30 years) and Group C (31 to 60 years) and, two sex groups (male and female) and two sides (right and left). A transverse section was made at the level of horizontal fissure, and length and breadth of dentate nucleus were measured by divider and scale. The mean (±SD) length and breadth of dentate nucleus was 8.619±2.995mm and 14.770±3.604mm respectively and it was observed that length and breadth of dentate nucleus increased with age upto certain level then slightly decreased in the late age Group C. In this study, differences of the mean length of dentate nucleus on both right and left sides were statistically moderately significant between age Groups A&B. The differences of mean breadth of dentate nucleus on both right and left side were statistically highly significant between age Groups A&B and moderately significant between age Groups A&C on right side and only significant on left side. The differences between male & female were statistically insignificant in length and breadth of dentate nucleus.

Abstract
Saline infusion sonography (SIS) has become a valuable diagnostic modality in gynaecology over the last three decades. SIS is now commonly employed for detailed evaluation of the uterine cavity as part of pre-treatment assessment in infertile women. The objective of this paper is review the scientific literature on SIS in infertility. Medline, Ovid and Cochrane databases were searched for relevant articles. The indications, technical aspects and the potential advantages of SIS are discussed. The efficacy and sensitivity of SIS are compared to hysteroscopy in the evaluation of uterine polyps, fibroids, intrauterine adhesions and uterine anomalies. Increasing evidence suggests the use of SIS prior to an in-vitro fertilization (IVF) cycle as it has increased sensitivity in the detection of intrauterine pathology. SIS is cost-effective and results in better patient satisfaction scores than hysteroscopy.

Abstract
INTRODUCTION Traumatic brain injury is a leading cause of disability in bicycle riders. Preventive measures including bicycle helmet laws have been highlighted; however, its protective role has always been debated. The aim of this study was to determine the utility of bicycle helmets in prevention of intra-cranial hemorrhage. We hypothesized that bicycle helmets are protective and prevent the development of intra-cranial hemorrhage. METHODS We performed a 4-year (2009-2012) retrospective cohort analysis of all the patients who presented with traumatic brain injury due to bicycle injuries to our level 1 trauma center. We compared helmeted and non-helmeted bicycle riders for differences in the patterns of injury, need for intensive care unit admissions and mortality. RESULTS A total of 864 patients were reviewed of which, 709 patients (helmeted = 300, non-helmeted = 409) were included. Non-helmeted bicycle riders were more likely to be young (p < 0.001) males (p = 0.01). There was no difference in the median ISS between the two groups (p = 0.3). Non-helmeted riders were more likely to have a skull fracture (p = 0.01) and a scalp laceration (p = 0.01) compared to the helmeted riders. There was no difference in intra-cranial hemorrhage between the two groups (p = 0.1). Wearing a bicycle helmet was not independently associated (p = 0.1) with development of intra-cranial hemorrhage. CONCLUSION Bicycle helmets may have a protective effect against external head injury but its protective role for intra-cranial hemorrhage is questionable. Further studies assessing the protective role of helmets for intra-cranial hemorrhage are warranted.

Abstract
Placenta is the mirror of maternal and fetal status; it reflects the changes due to complication in pregnancy of mother. Numerous common and uncommon findings of the placenta, umbilical cord and membranes are associated with abnormal fetal development and perinatal morbidity. So, the examination of the placenta can yield information that may be important in the immediate and later management of mother and newborn. This information may also be essential for protecting the attending physician in the event of an adverse maternal or fetal outcome. This cross sectional descriptive study was carried out to determine the incidence of different types of placenta depending on attachment site and branching pattern of arteries of umbilical cord in Bangladeshi Women. To achieve this aim sixty placenta with umbilical cord were collected. Placenta was from 28 weeks to 42 weeks gestational age of normal pregnancy during normal labour at gynaecology and obstetric department of Mymensingh Medical College Hospital. After preservation in 10% formol saline, study was done in the Department of Anatomy of Mymensingh Medical College. In the present study, incidence of different types of placenta depending on attachment site of umbilical cord was 50% Central, 46% Paracentral and 18% Marginal in type. In this study it was also observed that 58% placenta were Disperse in type and 42% were Magistral in type depending on the distribution of umbilical arteries. Observed findings of this study were compared with those of Western and Bangladeshi researchers.

Abstract
This cross sectional descriptive study was to measure the thickness of muscular layer in trigone of the urinary bladder and to establish the difference between sexes of different age groups in Bangladeshi cadaver. A total 60 human urinary bladders were collected by purposive sampling from May 2013 to October 2013. Among them from male 43 and from female 17 were collected from Bangladeshi cadavers of age ranging from 01 to 60 years, from autopsy laboratory of the Department of Forensic Medicine of Mymensingh Medical College, Mymensingh. The thickness of muscular layer in trigone of the urinary bladder was measured and significant differences of the value between age and sex groups were observed. The mean±SD thickness of muscular layer of trigone of the urinary bladder was 318.59±93.15μm in age Group A (01 to 20 years), 633.25±79.79μm in age Group B (21 to 40 years), and 352.50±116.15μm in age Group C (41 to 60 years). The mean difference of muscular layer of the trigone of the urinary bladder between age Groups A&B, B&C was statistically highly significant, where p=0.001. In statistical analysis, differences between age groups were calculated by using one way ANOVA test. The present study revealed that the value of thickness of muscular layer in trigone of the urinary bladder was increased with the increase of age and it was declined to a low level in the late age. The mean value of muscular layer of the trigone of the urinary bladder was higher in male than that of in female of Group A, B & C.

Abstract
This study aims to analyze the autonomic nervous system response during head-up tilt test (HUTT), by exploring the changes in dynamic properties of heart rate variability in subjects with and without syncopes, to predict the outcome of HUTT. Baroreflex response, as well as linear and non-linear parameters of RR-interval time series, have been extracted from the ECG of 66 subjects: 35 with and 31 without syncope during HUTT. The results show that, when considering the first 15 min of tilting position, the total power spectrum, the standard deviation, the long-term fractal scale of RR-interval and ΔRR-interval of time series increase, while the sample entropy decreases in the positive group compared to the negative one. These indices may be good predictors of positive response in patients with reflex syncope. Additionally, an analysis of the first 15 min of tilting position using kernel support vector machines leads to a correct classification of 85% of patients, within negative and positive response groups (specificity = 80.6% and sensitivity = 88.5%). In medical applications, it is important to avoid false negative diagnosis of syncopes during HUTT. Taking this into account, an overall accuracy of 72.1% can be obtained in the same window allowing the reduction of the examination time in the clinical domain.

Abstract
In this paper, a fractional-order model which describes the human immunodeficiency type-1 virus (HIV-1) infection is presented. Numerical solutions are obtained using a generalized Euler method (GEM) to handle the fractional derivatives. The fractional derivatives are described in the Caputo sense. We show that the model established in this paper possesses non-negative solutions. Comparisons between the results of the fractional-order model, the results of the integer model and the measured real data obtained from 10 patients during primary HIV-1 infection are presented. These comparisons show that the results of the fractional-order model give predictions to the plasma virus load of the patients better than those of the integer model.

Abstract
BACKGROUND Previous magnetic resonance imaging (MRI) studies have demonstrated increased iron deposition in the basal ganglia of multiple sclerosis (MS) patients. However, it is not clear whether these alterations are associated with changes of iron metabolism in body fluids. OBJECTIVES The purpose of this study was to investigate if iron metabolism markers in cerebrospinal fluid (CSF) and serum of clinically isolated syndrome (CIS) and MS patients differ from controls and how they relate to clinical and imaging parameters. METHODS We analysed serum ferritin, transferrin and soluble transferrin-receptor and CSF ferritin and transferrin by nephelometry in non-anaemic CIS (n=60) or early MS (n=14) patients and 68 controls. In CIS/MS we additionally assessed the T2 lesion load. RESULTS CSF transferrin was significantly decreased in CIS/MS compared to controls (p<0.001), while no significant differences were seen in serum. Higher CSF transferrin levels correlated with lower physical disability scores (r= -0.3, p<0.05). CSF transferrin levels did not correlate with other clinical data and the T2 lesion load. CONCLUSION Our biochemical study provides evidence that altered iron homeostasis within the brain occurs in the very early phases of the disease, and suggests that the transporter protein transferrin may play a role in the increased iron deposition known to occur in the brain of MS patients.

Abstract
BACKGROUND By increasing the hepatic blood circulation, food intake has been suggested to increase liver stiffness measurement (LSM) values in HCV-infected patients. AIM To investigate prospectively the effects of food intake on LSM in hepatitis B virus (HBV)-infected patients and healthy controls. METHODS In The Gambia, patients included in the PROLIFICA project are screened for HBV at the community level and then invited for fasting assessment including LSM. Between April 2012 and October 2012, each day, the first five participants were invited to participate in this study. After the initial examination, a standardised 850 Kcal breakfast was provided. Effect of food intake was assessed by examining mean difference of LSM, IQR and IQR/LSM at T0 (fasting LSM1), T30min (LSM2) and T120min (LSM3) respectively. RESULTS A total of 209 subjects were enrolled in this study (133 were HBV positive, 76 healthy controls). Unreliable measurements occurred more frequently after food intake (5%, 24% and 18% at T0, T30min and T120min respectively). In both groups, median LSM2 was significantly higher than LSM1 [6.2 (IQR: 5.4, 7.9)] vs. 4.9 (4.2, 6.2), P < 0.0001. LSM3 was still higher than the baseline, but lower than LSM2. In multivariable analysis, no factor modified the effect of breakfast on LSM. In a subgroup of patients having liver biopsies, we confirmed that food intake can overestimate liver fibrosis. CONCLUSIONS Food intake significantly increases liver stiffness measurement and its IQR values in patients with chronic hepatitis B as well as healthy individuals; and also the number of unreliable liver stiffness measurement values.

Abstract
Optical images were used to study the wetting behavior of water on graphite, sapphire, and quartz along the liquid vapor coexistence curve from room temperature to 300 °C. Wetting transitions were identified by the temperature at which the contact angle decreased to zero and also by the disappearance of dropwise condensation. These two methods yielded consistent values for the wetting temperatures, which were 185 °C, 234 °C, and 271 °C for water on quartz, sapphire, and graphite, respectively. We compare our results with the theoretical predictions based on a simplified model of the water-substrate potential and sharp interfaces.
