Prevalence of Thyroid Dysfunction in Type 2 Diabetes Mellitus.

The level of thyroid hormones is often changed in uncontrolled diabetic patients. Screening for Thyroid dysfunction (TD) among patients with Type 2 Diabetes mellitus (T2DM) should be performed considering the increased prevalence of thyroid disorders. This cross-sectional comparative study was conducted in outpatient department of Endocrinology and Medicine, Mymensingh Medical College Hospital, Mymensingh (MMCH) from 1st March 2020 to 30th August 2021. One hundred (100) patients with type 2 diabetes along with 100 (hundred) non-diabetic controls of same age group were enrolled in the study. After taking clinical data, patients were investigated to estimate Fasting plasma glucose (FPG), serum free tri-iodothyronine (FT3), free thyroxin (FT4) and thyroid stimulating hormone (TSH) level to see thyroid dysfunction. Patients were selected with purposive sampling. Thyroid dysfunction was found to be more in T2DM (15.0%) in comparison with non-diabetic controls (5.0%) and this difference was statistically significant (p=0.018). In both diabetic and non-diabetic groups, subclinical hypothyroidism and hypothyroidism were the most common thyroid dysfunction. Thyroid dysfunction was found more in 40-60 years that suggests the prevalence of thyroid dysfunction are increasing in diabetic patients with advancing age. Thyroid dysfunction was found more among overweight and obese patient in both groups. Mean BMI was found higher among diabetic patient with thyroid dysfunction. Logistic regression showed significant association of Thyroid dysfunction with age >50 years and high FPG level. We found thyroid dysfunction was more prevalent in patients with T2DM than non-diabetics. So, screening for thyroid dysfunction among type 2 diabetic patients by estimating Serum TSH, FT4 level should be performed.

A two-generational reproductive study to assess the effects of Juglans regia on reproductive developments in the male and female rats.

Environmental pollutants and lifestyle severely threaten human and animal health, leading to disturbances of various functions, including infertility. So, exploring a safe treatment that could effectively reverse infertility remains a challenge. The current study was intended to explore the fertility-enhancing effect of Juglans Regia oil in two successive generations of rats; F0 and F1. J. Regia oil was initially tested for in vitro antioxidant assay via ROS and DPPH, followed by in vivo toxicity testing. In the fertility assessment, eighteen pairs of male and female rats (n=36, 1:1, F0 generation) were divided into three groups and dosed with 1 mL/kg and 2 mL/kg daily of J. Regia oil and saline, respectively, up to pre-cohabitation, cohabitation, gestation and lactation periods. The reproductive performance, including body weight, live birth index, fertility index, and litter size, was assessed. Hormonal and antioxidant markers of F1 generations were assessed with the histopathological evaluation of male and female organs. The oil of J. Regia showed great antioxidant potential (P < 0.05) in DPPH (1,1-diphenyl-2-picrylhydrazyl) and ROS (Reactive Oxygen Species) methods (P<0.05). The continued exposure of the F0 and F1 generations to J. Regia oil did not affect body weight, fertility index, litter size, and survival index. We have found pronounced fertility outcomes in both genders of F0 and F1 generations with J. Regia 2 mL/kg/day in comparison to the control. Results showed that J. Regia significantly increased (P < 0.05) luteinizing hormone (LH), plasma testosterone, follicular stimulating hormone (FSH), glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities in both generations. Histology of both generations reveals improved spermatogenesis and folliculogenesis with enhanced architecture. Altogether, the present results suggest that J. Regia improved fertility in both male and female rats by improving hormonal activities and oxidative stress.

Association of Chest Pain with Rate Pressure Product and ST-segment Changes after Sub Arachnoid Block in Caesarean Section.

When healthy women undergo caesarean section (CS) under sub arachnoid anaesthesia, transient electrocardiographic changes, such as ST-segment depression and T-wave abnormalities, are observed. During an elective caesarean section under sub arachnoid anaesthesia, about one-third of healthy parturient experience chest pain and ECG changes suggestive of myocardial ischemia. To assess the ST-segment and Rate Pressure Product changes with chest pain in patients with elective caesarean section under subarachnoid block. The Department of Anesthesia, Analgesia and Intensive Care Medicine at Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh was the site of this prospective observational study. The study included 86 healthy women between the ages of 20 and 35 who needed an elective caesarean section under a single shot sub arachnoid block and who visited the Department of Anesthesia, Analgesia, and Intensive Care Medicine at BSMMU in Shahbagh, Dhaka from January 2019 to June 2019. In comparison to the no chest pain group, ST-segment changes among the chest pain group at delivery, 5 minute, 10 minute after delivery and at the end of the surgery were highly significant (p=0.001). Comparatively, Rate Pressure Product changes were found to be significantly higher in the group with chest pain than in the group without chest pain (p=0.001). It is concluded that there is a substantial association of chest pain with rate pressure product and ST-segment changes after subarachroid block in caesarean section.

Magnetic Resonance Imaging Evaluation of Common Spinal Intramedullary Tumours: Ependymoma and Astrocytoma.

This cross-sectional study was carried out in the Department of Radiology and Imaging, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, from January 2015 to June 2016 in collaboration with Department of Neurosurgery and Department of Pathology of same hospital, to assess MRI findings of common IMSCTs and to find out the validity of MRI in the diagnosis of spinal ependymoma and astrocytoma, thereby differentiating these two common intramedullary entities. For this purpose, 40 patients aged from 15 to 60 years, who were diagnosed or suspected cases of having intramedullary spinal cord tumours were enrolled. These patients underwent preoperative MRI for evaluation of the spinal cord tumours during the study period in department of Radiology and Imaging. Also, patients were diagnosed by MRI as having IMSCTs incidentally was included. All of them were followed by histopathological examination of the same lesions after surgery. Among these 40 patients after exclusion for valid reason 28 cases were included as study population. MR images were obtained on a 1.5 Tesla (Avanto Magnatom, Siemens) unit with a spine surface coil. MRI findings were compared with histopathology after surgery keeping histopathology as gold standard. Out of 28 clinically and MRI diagnosed IMSCTs cases, 19 cases of ependymoma, 8 cases of astrocytoma and one diagnosed as hemangioblastoma by MRI. The mean age was 34.11±9.55 years, ranging from 15 to 56 years for ependymoma, 26.88±8.08 years ranging from 16 to 44 years for astrocytoma. Highest incidence (47.4%) was in between 31 to 40 years for ependymoma, 50.0% were in between 21-30 for Astrocytoma. On MRI majority 12(63.2%) of the cord ependymomas and majority 5(62.5%) of astrocytomas were in cervical region. While considering axial location ependymomas are mostly 17(89.5%) central and astrocytomas 5(62.5%) are eccentric in location. It was observed that out of 19 cases of ependymoma more than half 10(52.6%) had elongated shape, 12(63.1%) had well defined margin. Associated syringohydromyelia was present in 16(84.2%) cases. On T1WI 11(57.9%) and 8(42.1%) cases were iso and hypo respectively. On T2WI 14(73.7%) cases were hyper intense. After Gd-DTPA in most cases, 13(68.4%) cases showed diffuse enhancement. Noticeable and sizeable solid component observed among 13(68.4%) of the cases. Hemorrhage with cap sign was found in more than one third 7(36.8%) cases. Out of 8 cases of astrocytomas 4(50.0%) had lobulated shape, ill-defined margin 5(62.5%). T1WI: Iso 5(62.5%), hypo 3(37.5%), T2WI: hyper 5(62.5%), After Gd-DTPA: focal and heterogenous enhancement 3(37.5%) and rim enhancement 4(50.0%). Component: mixed 4(50.0%), cystic 3(37.5%) and solid 1(12.5%). Hemorrhage without cap sign 2(25.0%), associated syringohydromyelia 1(12.5%). In the case of evaluation of intramedullary ependymoma sensitivity of MRI in the present series is 94.44%, specificity 80.0%, Positive predictive value (PPV) 89.5%, Negative predictive value (NPV) 88.9% and accuracy 89.28%. In case of MRI evaluation of intramedullary astrocytoma sensitivity of MRI in the present study is 85.71%, specificity 90.47%, PPV 75%, NPV 95% and accuracy 89.2%. Thus present study shows MRI is a sensitive and effective noninvasive imaging modality in diagnosing common intramedullary spinal cord tumours.

Dexmedetomidine as an Adjuvant to Bupivacaine in Caudal Analgesia in Children Undergoing Infra-Umbilical Surgery.

When performing infra-umbilical procedures, caudal epidural analgesia with bupivacaine is frequently used to provide both intra- and post-operative analgesia. Dexmedetomidine, an alpha 2 agonistsare extensively used in neuraxial blocks and peripheral nerve blocks to prolong the action of bupivacaine. To find out the effects of dexmedetomidine as an adjuvant to bupivacaine for caudal analgesia in children undergoing infra-umbilical surgery. This was a randomized, controlled double-blinded prospective observational study and was performed from July 2019 to December 2019. A total of 60 (Sixty) patients with different infra-umbilical surgical problems underwent different procedure under caudal anaesthesia in different operation theatre in Bangabandhu Sheikh Mujib Medical University, Dhaka were enrolled in this study. Elaborate personal history, meticulous clinical examinations and relevant laboratory investigations was done. Post-operative adverse effects also were monitored. All information from history of illness, clinical, laboratory findings, duration of analgesia and post-operative adverse effects were recorded in a preformed data sheet (Appendix-I) and statistical analysis was done by SPSS 22.0. Mean age of the children in Group A (dexmedetomidine + bupivacaine) was 5.50±2.61 years and in Group B (bupivacaine) was 5.66±2.75. Mean weight of the children in Group A was 19.22±8.58 kg and in Group B was 19.70±8.94 kg in this study. Mean duration of anaesthesia was 27.5±6.5 minute in Group A and 28.5±5.5 minute in Group B. The mean duration of analgesia was 4.32±0.54 hours for Group A and 2.12±0.32 hours in Group B. In Group A, 46.7% patients required 1 and 3.3% required 2 rescue analgesic but in Group B, 43.3% patients required single rescue analgesic and 33.3% required two rescue analgesics (p<0.05). In Group A, 6.7% patients had nausea/ vomiting and in Group B, 16.7% patients had nausea/ vomiting (p>0.05). It can be concluded that dexmedetomidine with bupivacaine for caudal analgesia in infra-umbilical surgery significantly prolongs the duration of postoperative analgesia when compared to bupivacaine alone without any side-effects.

Antenatal and postnatal factors associated with neonatal death in the Indian subcontinent: a multilevel analysis.

OBJECTIVES: This study aimed to identify significant antenatal and postnatal factors associated with neonatal death at 2-7 days and at 2-28 days in the Indian subcontinent. Results from this study may help guide strategies to improve antenatal and postnatal care services and reduce neonatal mortality. STUDY DESIGN: Nationally representative recent Demographic and Health Survey data sets from five countries, including Bangladesh, India, Pakistan, Maldives and Nepal, were used. METHODS: Survey-weighted univariate distributions were used for study population characteristics and bivariate distributions, along with the chi-squared test for unadjusted associations. Finally, multilevel logistic regression models were performed to determine the association of antenatal care (ANC) and postnatal care (PNC) factors with neonatal deaths. RESULTS: Among 200,499 live births, the highest neonatal death rate was observed in Pakistan, followed by Bangladesh, whereas the lowest rate was in Nepal. After adjusting for sociodemographic and maternal control variables, the multilevel analysis showed a significantly lower likelihood of neonatal death at 2-7 days and 2-28 days with ANC visits <12 weeks' gestation, at least four ANC visits during pregnancy, PNC visits within the first week after birth and breastfeeding. Delivery at home by a skilled birth attendant compared to unskilled birth attendant was significantly associated with lower neonatal death at 2-7 days. Multifoetal gestation was significantly associated with higher neonatal death at 2-7 days and at 2-28 days. CONCLUSIONS: The findings suggest that strengthening ANC and PNC services will improve newborn health in the Indian subcontinent and decrease neonatal mortality.

Diagnostic Accuracy of Magnetic Resonance Imaging in Evaluation of Anterior Cruciate Ligament Tear.

The anterior cruciate ligament (ACL) is the most generally injured one of the major knee ligaments. These injuries plague both athletes and non-athletes. This cross-sectional and comprehensive study was conducted in the Department of Radiology and Imaging collaborating with Department of Orthopedics of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, completed from January 2014 to December 2015. The study evaluated the role of MRI in the diagnosis of anterior cruciate ligament injury of knee joint, keeping Arthroscopy as standard, compared the MRI and arthroscopic findings to determine accuracy, sensitivity and predictivity of MRI in the diagnosis of ACL injury in knee joint. For this purpose, a total of 50 patients having clinical suspicion of ACL injury in knee joint were enrolled in this study to perform MRI and Arthroscopy. MRI was done in all these patients. Clinically suspected but MRI diagnosed as no ACL injury, patients who were not willing to undergo arthroscopy examination and patient who were not fit for arthroscopy were excluded from the study. More than half (52.0%) of the patients were in 3rd decade and male to female ratio was 3.5:1. Less than one fourth (24.0%) of the patients were service holder. Forty two percent patients had duration of suffering for 2 weeks. Most 49(98.2%) patients had history of trauma, 45(90.0%) had pain in Knee joint, 24(48.0%) had difficulty in walking, 19(38.0%) had swelling in Knee joint and 13(26.0%) had restricted range of motion. Anterior drawer test was 37(74.0%) and Lachman test 16(32.0%). Loss of normal contour of ACL was found in 50.0%. Signal change of ACL in PD and T2W1 was found 42(84.0%) patients, and thickened ACL in 33(66.0%) patients. In MRI diagnosis tear was present in 80.0% of the patients. ACL tear diagnosed by MRI among the patients, 20(40.0%) had partial tear and 20(40.0%) had complete tear. In arthroscopy diagnosis 38(76.0%) had tear present. ACL tear diagnosed by arthroscopy of the patients 15(30.0%) had partial tear and 23(46.0%) had complete tear. Majority 20(40.0%) patients had medial meniscus injury, 15(30.0%) had lateral meniscus injury, 11(22.0%) had PCL injury, 4(8.0%) had lateral co-lateral ligament injury and 2(4.0%) had medial co-lateral ligament injury. In MRI diagnosis of anterior cruciate ligament tear, 37 cases were true positive, three cases false positive, one case false negative and nine cases was true negative. The validity of MRI diagnosis evaluation for anterior cruciate ligament tear was 97.4% sensitivity, 75.0% specificity, 92.0% accuracy, 92.5% positive predictive values and 90.0% negative predictive values.

Evaluation of Liver Function Tests in ß-Thalassemia Major Children.

Thalassemia is the most prevalent single gene defect in human beings worldwide. Repeated blood transfusions along with chelation therapy are mainstay of treatment in thalassemia patients. However these recurrent blood transfusions result in iron overload which along with chelation therapy causes deterioration of liver function. Aim of the study was to evaluate the liver function tests in ß-thalassemia major patients. This cross sectional study was conducted in the Department of Biochemistry, Dhaka Medical College, Dhaka, Bangladesh from January 2017 to December 2017. In this study, 50 diagnosed patients of ß Thalassemia major (Group A) and 50 apparently healthy children (Group B) of both sexes were selected from the department of Paediatrics, Dhaka medical college. The study parameters were serum ferritin, bilirubin, AST, ALT, ALP. The results were compared statistically between groups. Serum ferritin level (mean±SD) in thalassemic major patients in Group A (890±446.38 microgram/L) which is significantly higher above normal level. Serum bilirubin in Group A (3.27±2.62 mg/dl) and in Group B (0.48±0.24 mg/dl), Serum ALT in Group A (53.06±34.0 U/L) and in Group B (16.70±4.81 U/L), AST in Group A (84.56±33.54 U/L) and in Group B (11.60±2.72 U/L) and ALP levels in Group A (422.42±226.99 IU/L) and in Group B (221.86±80.54 IU/L). All the values were significantly higher (p<0.001) in ß-thalassemia patient than that of normal children. This study concludes that liver function parameters are significantly higher in ß thalassemia major patients. So routine evaluation of liver function tests may be advocated for thalassemic patients to predict early onset of hepatic dysfunction.

Clinical Profile and Immediate Outcome of Pyogenic Meningitis in Children.

Meningitis literally means inflammation of the meninges. It is mostly caused by bacteria, virus, fungus and protozoa and pyogenic meningitis constitutes a serious neurological disorder associated with significant morbidity and mortality in developing countries. This study was carried out to evaluate the clinical presentation and immediate outcome of pyogenic meningitis in children. This was a prospective observational study and conducted at department of Paeditrics in Cumilla Medical College Hospital, Cumilla, Bangladesh from July 2014 to June 2015. Total 50 children were diagnosed as pyogenic meningitis fulfilling the inclusion criteria was included in this study. Cases were enrolled purposively. Immediately after admission through history and clinical examination, complete blood count, random blood sugar, Cerebrospinal fluid (CSF) examination and blood culture was done in all patients. For statistical analysis chi-square test was done and significance of analysis was made when p value <0.05. This study includes patients aged between 2 months to 12 years and male female ratio was 1.5:1. Several risk factors like male sex (60.0%), age below one year (42.0%), Protein energy malnutrition (PEM) (30.0%), not exclusively breastfed (44.0%) were identified. Common presenting complaints were fever (100.0%), convulsion (96.0%), altered consciousness (42.0%) and vomiting (38.0%). Common physical signs were neck rigidity (56.0%), Kernig's sign (26.0%) and bulged fontanelle (34.0%). CSF was hazy in 54.0%, clear in 38.0% and turbid in 08.0% cases, CSF protein was more than 100mg/dl in 90.0% of the cases and glucose was less than 40mg/dl in most of the cases (94.0%). Streptococcus Pneumoniae (49.0%) followed by Neisseria Meningitidis (38.0%) were the two most commonly isolated organism responsible for pyogenic meningitis. Mortality rate during hospital stay was 18.0% and complications developed in 18.0% of cases. To avoid maltreatment in our resource limited setting due to failure of identifying organism, this study might help to administer appropriate antibiotics against organism and to reduce morbidity and mortality in meningitis. This study revealed less mortality rate in our country than neighbors and severe malnutrition important risk factors for the burden of pyogenic meningitis. It requires large scale multicentre studies to establish the whole scenario of Bangladesh.

Number and Diameter of White Pulp of Spleen in Different Age and Sex Groups of Bangladeshi People.

Spleen is a haemo-lymph organ and belongs to the reticuloendothelial system of human body, develops from mesodermal proliferation between the two leaves of dorsal mesogastrium. The microscopic structure of spleen is variable depending on the developmental stage of the organ, and the age and immune status of the individual. In our country, we depend on foreign data which came from the subjects of different races and from the individuals under different geographic conditions. So the study was carried out to minimize the dependency on foreign standards and to identify the diameter of white pulp in different age and sex of the Bangladeshi individuals with a view to establish local data bank related to spleen of Bangladeshi people. This cross-sectional descriptive study was performed on 65 postmortem human spleens (34 of male and 31 of female) to find out the number and diameter of white pulp of spleen of Bangladeshi people by purposive sampling technique. And done in Autopsy laboratory of the Department of Forensic Medicine of Mymensingh Medical College, Bangladesh from 16th October 2016 to 15th January 2017. The samples were divided into three age groups including Group A (5-20 years), Group B (21-40 years) and Group C (41-60 years). Dissection was performed according to standard autopsy techniques. For statistical analysis, unpaired student 't' test was done. The mean±SD number of white pulp of male spleen was greater than female spleen in Group A, B and C but mean±SD diameter of white pulp of female spleen was found greater than male spleen in all groups. Comparison of number of white pulp between sexes showed that statistically there was no significant difference within all the age groups at p>0.05 level. No age change was evident in diameter of white pulp but in between sexes, diameter is greater in females than males. Mean difference of diameter of white pulp between sexes showed no significant difference within the age groups at p>0.05.

Age Related Changes in the Purkinje Cells in Human Cerebellar Cortex in Bangladeshi People.

This study was done to see the changes in the number of Purkinje cells per square mm in different age groups of Bangladeshi people. This cross-sectional descriptive type of study was done on total 40 postmortem human cerebellums, in the Department of Anatomy, Mymensingh Medical College, Bangladesh from July 2016 to June 2017. The specimens were collected from morgue in the department of Forensic Medicine, Mymensingh Medical College, by purposive sampling technique. All the specimens were grouped into four categories: Group A (20 to 29 years), Group B (30 to 39 years), Group C (40 to 49 years) and Group D (50 to 59 years). Paraffin blocks of cerebellum were cut at 4-5µm thickness and stained with routine "Haematoxylin and Eosin" (H & E) stain. Estimation of number of Purkinje cell was done by using the counting circle and examined under the light microscope. In the present study, the mean±SD number of Purkinje cell was found 128.67±25.15 per sq mm in Group A, 136.53±34.45 in Group B per sq mm, 135.55±29.44 per sq mm in Group C, 127.69±35.31 per sq mm in Group D.

Correlation between Length of Ala and Transverse Diameter of First Sacral Vertebral Body in both Sexes.

Sacrum is a triangular bone formed by the fusion of five sacral vertebrae. It is situated near the lower end of the spinal column, where it joins both hip bones to form the posterio superior wall of the pelvic cavity. It is an important bone for identification of sex in human skeletal system. This cross sectional and descriptive study was done among 150 (59 male and 91 female) fully ossified dry human sacrum in Mymensingh Medical College, Mymensingh, Bangladesh from January 2017 to December 2017. The sex of sacrum was determined by previously measured different parameters. Sample collection was done by purposive sampling technique from anatomy department of Mymensingh Medical College and Community Based Medical College of Bangladesh, Mymensingh. The parameters included the length of ala and transverse diameter of first sacral vertebral body which were measured by digital vernier slide caliper and was expressed in mm. In present study the mean length of ala in male and female were 29.21±6.30mm and 30.77±5.56mm respectively. The mean transverse diameter of first sacral vertebral body in male and female were 48.10±4.83mm and 44.05±6.16mm respectively. Comparison of both length of ala and transverse diameter of first sacral vertebral body was done between male and female by unpaired student 't' test which was statistically significant. There was positive correlation between these two parameters and the differences were statistically highly significant in both sexes.

A smartphone based method for mouse fundus imaging.

Noninvasive in vivo imaging of the mouse retina is essential for eye research. However, imaging the mouse fundus is challenging due to its small size and requires specialized equipment, maintenance, and training. These issues hinder the routine evaluation of the mouse retina. In this study, we developed a noncontact imaging system consisting of a smartphone, a 90D condensing lens, a homemade light diaphragm, a tripod, and a Bluetooth remote. With minimal training, examiners were able to capture fundus images from the mouse retina. We also found that fundus images captured using our system from wild type mice, mice with laser-induced retinal injury, and a mouse model of retinitis pigmentosa showed a quality similar to those captured using a commercial fundus camera. These images enabled us to identify normal structures and pathological changes in the mouse retina. Additionally, fluorescein angiography was possible with the smartphone system. We believe that the smartphone imaging system is low cost, simple, accessible, easy to operate, and suitable for the routine screening and examination of the mouse eye.

Experimental study and parameters optimization of microalgae based heavy metals removal process using a hybrid response surface methodology-crow search algorithm.

This study investigates the use of microalgae as a biosorbent to eliminate heavy metals ions from wastewater. The Chlorella kessleri microalgae species was employed to biosorb heavy metals from synthetic wastewater specimens. FTIR, and SEM/XRD analyses were utilized to characterize the microalgal biomass (the adsorbent). The experiments were conducted with several process parameters, including initial solution pH, temperature, and microalgae biomass dose. In order to secure the best experimental conditions, the optimum parameters were estimated using an integrated response surface methodology (RSM), desirability function (DF), and crow search algorithm (CSA) modeling approach. A maximum lead(II) removal efficiency of 99.54% was identified by the RSM-DF platform with the following optimal set of parameters: pH of 6.34, temperature of 27.71 °C, and biomass dosage of 1.5 g L-1. The hybrid RSM-CSA approach provided a globally optimal solution that was similar to the results obtained by the RSM-DF approach. The consistency of the model-predicted optimum conditions was confirmed by conducting experiments under those conditions. It was found that the experimental removal efficiency (97.1%) under optimum conditions was very close (less than a 5% error) to the model-predicted value. The lead(II) biosorption process was better demonstrated by the pseudo-second order kinetic model. Finally, simultaneous removal of metals from wastewater samples containing a mixture of multiple heavy metals was investigated. The removal efficiency of each heavy metal was found to be in the following order: Pb(II) > Co(II) > Cu(II) > Cd(II) > Cr(II).

Prevalence of Diabetic Nephropathy in Patients Attending the Endocrine Department of Mymensingh Medical College Hospital.

Diabetic nephropathy (DN) is the leading cause of end-stage renal disease worldwide. Due to severe morbidity and mortality of DN and limited effective therapies, research has mainly focused on prevention of this debilitating illness by modification of risk factors. Aims of this study were to find out the prevalence of diabetic nephropathy, its factors and to correlate the functional status of the kidney. This cross-sectional study was conducted in the Department of Endocrinology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from 1st January 2013 to 30th June 2013. A total 105 patients having clinical diagnosis of Diabetes mellitus were enrolled in this study. Data were collected by interview of the patients, clinical examination and laboratory investigation. Data was analyzed using the Chi-square test for Categorical variables and unpaired Student's 't' test for differences in means for continuous variables. P value <0.05 was considered significant. With DN (30.5%) patients 21.1% had micro-albuminuria and 9.5% had macro-albuminuria. The mean age for the DN patient was 47.9±14.7 years and male female ratio was 1:1. BMI was found significantly low in patients with DN (p<0.05). Prolonged duration of diabetes (>5 years) and uncontrolled diabetes were found as significant risk factors associated with DN. Other risk factors were hypertension, family history of hypertension, family history of diabetes mellitus and irregular treatment of diabetes mellitus. Mean serum creatinine, mean estimated glomerular filtration rate (GFR) and mean blood sugar level was 1.3±0.6mg/dl, 69.4±26.7ml and 15.6±7.1mmol/L respectively in DN patients. Relation was significant for higher serum creatinine and lower eGFR values (p<0.05). Prevalence of diabetic nephropathy was 30.5%. Long standing diabetes (>5 years) and uncontrolled diabetes were the important risk factors for the development of diabetic nephropathy. Diabetic nephropathy is associated with higher serum creatinine and lower eGFR values.

Doppler Evaluation of Carotid Vessels in Type 2 Diabetes.

Type 2 diabetes considered as a compound of metabolic syndrome. It can cause both micro and macrovascular complications. Diabetes is a strong risk factor in the development of atherosclerosis and likewise carotid artery disease. Carotid artery stenosis may cause stroke. Doppler ultrasound is the most common imaging technique for the diagnosis of carotid disease. Objective of the study was to assess the percentage of atherosclerotic carotid disease in asymptomatic Type 2 diabetics (T2D) by Doppler sonography and to find out the association of different risk factors of diabetic patient with atherosclerosis. A cross sectional study was done. A total of 43 type 2 diabetic patients (27 male, 16 female) referred from the out patient department and admitted patients in Mymensingh Medical College Hospital (MMCH) during January 2017 to December 2017 for the purpose of evaluation of intima media thickness (IMT) and carotid artery stenosis by Duplex color Doppler ultrasonography examination were enrolled in this study. Patients with previous history of recent stroke or transient ischemic attack (<6 weeks), history of carotid surgery or cervical radiotherapy were excluded. Carotid artery disease was found 65.1% in asymptomatic type 2 diabetics. Among them increased IMT in 48.8% and carotid stenosis was present in 37.2% and >50% stenosis (Peak systolic velocity >125cm/sec) was present in 9.3%. Age >50% years, smoking, duration of DM >10 years, hypertension, history of ischaemic heart disease and history of diabetic retinopathy were found to be associated with carotid atherosclerosis as well as carotid stenosis. High percentage of carotid artery disease (65.1%) was found in asymptomatic type 2 diabetes mellitus. This result suggests the need for carotid Doppler evaluation of all Type 2 diabetics as a first measure of stroke prevention, with the hope that timely intervention might avert stroke and its accompanying disability.

Length of Umbilical Cord in Different Gestational Age Groups of Healthy Pregnant Mother of Bangladesh.

This cross sectional descriptive study was performed on 80 human placenta and umbilical cord to find out the variation in length of umbilical cord of healthy Bangladeshi mother in relation to different gestational age. This study was conducted in the Department of Anatomy, Mymensingh Medical College, Mymensingh, from January to December 2018. The specimens were collected from the Department of Gynaecology and Obstetrics, Mymensingh Medical College Hospital, Mymensingh, Bangladesh by purposive sampling technique. According to gestational age the collected samples were divided into three groups. They were Group A (28 to 36 weeks), Group B (37 to 40 weeks) and Group C (above 40 weeks) and examined morphologically by fine dissection method. The length of umbilical cord was measured with the help of flexible tape in cm. For statistical analysis, differences of length between age groups were analyzed by using unpaired student 't' test. The mean±SD length of umbilical cord was 56.15±7.61cm in Group A, 62.54±8.78cm in Group B and 68.54±10.53cm in Group C. It was also observed that the mean length of the umbilical cord was increased with increase of gestational age. The mean difference of length of umbilical cord between Groups A and C was statistically highly significant (p<0.001), difference between Groups A and B was statistically moderately significant (p<0.01) but the difference between Groups B and C was statistically significant (p<0.05). This study was done to provide information about the length of umbilical cord in different gestational ages of healthy pregnancies.

Diagnostic Evaluation of Isotropic 3D MRCP Images in the Diagnosis of Cholangiocarcinoma.

This is a cross sectional study to establish that Magnetic resonance cholangiopancreatography (MRCP) could be accepted as the most effective imaging modality for the diagnosis of cholangiocarcinoma. Cholangiocarcinoma is the most common malignant tumor of the bile duct. It is much less common than hepatocellular carcinoma, accounting for 5-30% of all hepatic malignancies. Clinically suspected patients with obstructive jaundice due to cholangiocarcinoma were referred to the Department of Radiology and Imaging, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. The study was carried out in 60 patients, of which 38(63%) were male and 22(37%) were female. Out of 60 cases 56 cases were truly diagnosed by MRCP, 4 were normal, among these 1 case was diagnosed as cholangiocarcinoma as compared with histopathology. Forty four (44) patients (73.2%) of the patients were in sixth decade of life. The overall sensitivity and specificity were found to be 98.2% and 75%. The diagnostic accuracy was 96.7% & positive predictive value was about 98%.

Variations in the Position of Vermiform Appendix in Bangladeshi People.

This cross sectional descriptive study was performed on 70 postmortem vermiform appendices (male 34 and female 36) to find out the various positions of vermiform appendix of Bangladeshi people. The specimens were collected from autopsy laboratory of the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh, Bangladesh by purposive sampling technique from October 2016 to March 2017. The collected samples were divided into four age groups. They were Group A (upto 20 years), Group B (21 to 40 years), Group C (41 to 60 years) and Group D (above 60 years). Dissection was performed according to standard autopsy technique. During postmortem examination abdominal cavity was routinely exposed by classical midline incision from xiphoid process to the symphysis pubis and a semicircular incision around the umbilicus and the flaps were reflected to give a good view of the abdominal cavity along with its contents and then the taeniae coli of the caecum were identified. The three taeniae coli of the caecum converge at the base of the appendix and become its longitudinal muscle coat. The anterior caecal taeniae coli acts as the best guide for identification of the vermiform appendix. The relation of the base of the appendix to the caecum is constant but the position of the vermiform appendix, which is variable, was studied in relation to caecum and the terminal part of the ileum. Accordingly the position of the vermiform appendix was noted either retrocaecal, pelvic, preileal or postileal, subcaecal. All data were recorded in the predesigned data sheet, analyzed by SPSS program (version 21, 2012) and compared with the findings of other national and international studies and standard text books. Among 70 specimens, 44(62.9%) vermiform appendices were retrocaecal in position. The next common position was pelvic which was in 22(31.4%) specimen followed by postileal in 3(4.3%) specimen and subcaecal was observed only in 1(1.4%) specimen. In this study in all age groups incidence of retrocaecal vermiform appendix was highest and it was about 67.6%, 50%, 69.2% and 72.7% in Group A, B, C, D respectively. Pelvic position was 7.1%, 46.9%, 23.1% and 27.3% in Group A, B, C, D respectively. Subcaecal vermiform appendix was absent in Group A, B and Group D. On the other hand postileal vermiform appendix was absent in Group C and Group D. The findings of this study may help the physician and the surgeons for proper diagnosis, management and treatment of disease of vermiform appendix.

Performance of Haematological Parameters in Early Diagnosis of Clinically Suspected Neonatal Sepsis.

Neonatal sepsis is one of the major health problems throughout the world and major cause of morbidity and mortality in developing countries. Positive blood culture considers the gold standard for confirmation of neonatal sepsis, but it does not provide rapid diagnosis. So this study was designed to find out the performance of haematological parameters in early diagnosis of neonatal sepsis. The objective of the study was to evaluate the performance of haematological parameters individually and in combination in early diagnosis of neonatal sepsis. It was a cross-sectional study conducted at neonatal ward, SCANU and obstetric ward of Rangpur Medical College Hospital from January 2014 to December 2015. A total of 70 neonates clinically suspected to have features of sepsis were included in this study. Another 70 healthy term neonates were included in the study as reference group. Blood sample were obtained to estimate TLC, ANC, immature neutrophil count, degenerative changes in PMNs, platelet count, I/T and I/M ratio. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the individual test and tests combination were calculated. Among the haematological parameters, performance of combined tests had high sensitivity, specificity, with PPV and NPV. Among the individual tests I/T and I/M ratio had high sensitivity (95%), specificity (85%, 90%), PPV (90%, 75%) and NPV (90%). There were 22 out of 70 neonates (31.42%) who had culture proven sepsis. Among 22 culture proven sepsis most commonly found organism were Escherichia Coli 12(54.5%) followed by Klebsiella 3(13.63%), Proteus 3(13.63%), Staphylococcus aureus 2(9.9%) and Salmonella 2(9.9%). There is no ideal test for diagnosis of early diagnosis of neonatal sepsis haematological parameters is useful adjunct test in identifying clinically suspected neonatal sepsis.
