Abstract
Variety of conditions may be responsible for low back pain but lumber spinal canal stenosis is an important cause of low back pain. Lumber spinal canal stenosis usually presents with low backache with neurogenic claudication and shortness of walking distance in adult patient. Surgical management of lumbar spinal canal stenosis by decompression surgery is effective method. This prospective interventional study was performed in patient with clinical features like low back pain with radicular pain, neurogenic claudication, signs of root compression, positive MRI findings attending in department of Orthopaedic Surgery Mymensingh Medical College Hospital and Private Hospital from July 2016 to June 2019. Thirty patients were evaluated among those 20(66.6%) were 50 years and above. The mean age was 47.5±1.6 years. Male to female ratio was roughly 8:1. Almost all of the patients had low backache with radiation to the back of the thigh and leg with motor weakness (60%). About 66.6% of the patients had sensory deficit and 83.3% had neurogenic claudication. Majority (80.0%) of the patients at presentation had a suffering of 12 or >12 months. The mean duration of suffering was 14.7±5.1 months. About 55% of the patients were able to perform heel-walking and 36.0% tip-toe walking. Nearly 57% of the patients had sensory deficit along the distribution of 1st sacral nerve and 53.3% along the distribution of lumber 5 nerves. Diagnosis shows that 16.6% of patients had L4 lesion, 50% L5, 10.0% patients had L4 & L5 and 46.6% S1. Laminectomy was done in 26.6% of patients, laminectomy and disectomy in 33.3% and laminectomy, discectomy & foraminal decompression in 40.0% of patients. Twenty five (83.5%) of patients was free from symptoms. Eighty percent (80.0%) of patients shows minimal disability and 20.0% moderate disability on the basis of Oswestry Disability Index, while by MacNab criteria, most (80%) of patients was excellent, 10% good and another 10% fair. Repeated measure ANOVA statistics showed that mean Oswestry score decreased significantly from 54.5% at baseline to 22% at the end of 1 year (p<0.001).

Abstract
Currently, the development of the sodium-ion (Na-ion) batteries as an alternative to lithium-ion batteries has been accelerated to meet the energy demands of large-scale power applications. The difficulty of obtaining suitable electrode materials capable of storing large amount of Na-ion arises from the large radius of Na-ion that restricts its reversible capacity. Herein, Mn2O3 powders are synthesised through the thermal conversion of MnCO3 and reported for the first time as an anode for Na-ion batteries. The phase, morphology and charge/discharge characteristics of Mn2O3 obtained are evaluated systematically. The cubic-like Mn2O3 with particle sizes approximately 1.0–1.5 µm coupled with the formation of Mn2O3 sub-units on its surface create a positive effect on the insertion/deinsertion of Na-ion. Mn2O3 delivers a first discharge capacity of 544 mAh g−1 and retains its capacity by 85% after 200 cycles at 100 mA g−1, demonstrating the excellent cyclability of the Mn2O3 electrode. Therefore, this study provides a significant contribution towards exploring the potential of Mn2O3 as a promising anode in the development of Na-ion batteries.

Abstract
Rett syndrome is a disorder of early brain development which is clinically characterized by arrested neuro-development. We found one such 5.5 years old girl whose physical and mental development was normal up to 17 months of age, followed by regression. She had lost her already acquired purposeful hand movements, appearance of stereotyped hand movements, along with development of epilepsy. To our knowledge such case is being reported for the first time from Bangladesh. The purpose of this case report is to increase awareness of this syndrome among physicians specially paediatricians, thereby aiding early diagnosis and treatment.

Abstract
Suicide is one of the important cause of death worldwide. The precise effect of childhood adversities as risk factors for the onset and persistence of suicidal behaviour are not well understood. A descriptive cross sectional study was carried out in the department of Psychiatry, Cumilla Medical College, Cumilla, Bangladesh. All cases were selected from patients attending at Cumilla Medical College hospital and Private Hospitals in Cumilla City from April 2017 to September 2018. We found out the association between childhood adversities and suicidal behaviour over the life course and delineated the types of suicidal behavior. Total 120 cases were included in the study. Respondents provided socio-demographic and diagnostic information, childhood adversities as well as an account of suicide-related thoughts and behaviours. A participation rate was 77.5% female. Of 120 suicidal behavior participants physical abuse was 2.5%, sexual abuse was 16.67%, parental death was 5%, parental divorce was 2.5%, other parental loss was 4.17%, family violence was 5%, physical illness was 1.67%, financial adversity was 3.33% and composite adversity was 59.16%. Among childhood adversities participants suicidal ideation was 70%, suicidal plans was 15.83%, suicidal attempts was 45%, ideators only proceeded to plans was 22.5%, ideation to attempt was 63.33%, planned attempts was 10.83% and impulsive attempts was 52.5%. Among suicidal behavior participant's psychiatric disorders were 65%. Where neurotic disorders were 17%, psychotic disorders were 13%, personality disorders were 44% and others disorder was 26%. Most of the suicidal behavior patients were female 77.5% and age group of 18-24 years. Childhood sexual abuse emerged as a particularly robust risk factor for suicide attempts in younger participants. Childhood physical and sexual abuse emerged as risk factors for the emergence and persistence of suicidal behaviour, especially in adolescence. Two or more childhood adversities were associated with a three fold higher risk of lifetime suicide attempts. Childhood adversities are main risk factors for the onset and persistence of suicidal behaviour. The risks being are the greatest in childhood, adolescence and early adult. A longitudinal follow-up study is required to give a more reliable in Bangladesh.

Abstract
Pereinatal asphyxia is one of the most important complications related with the process of birth and this complications affect not only the brain but also many other organs. The purpose of this cross sectional study is to compare the role of craniosonogram and CT scan of the brain to delineate the cerebral pathology in respondent of preterm and term infant and to assess the Kappa test for agreement. This study was carried out in the department of Radiology & Imaging of Mymensingh Medical College Hospital, during the period of July 2015 to June 2017. A total number of 40 neonates clinically diagnosed as perinatal asphyxia referred for Craniosonogram and Computed tomography (CT) were included in this study. The test of agreement of USG in detection of neonatal cerebral pathology was calculated. Male to female ratio was 1:1.4. More than half (55.0%) patients were preterm age. The mean birth weight was found 2.3±0.6 kg and mean age was 22.7±12.7 days. Fifty five percent respondent mothers had antenatal check up and 27% had anemia, 11% had premature rupture of membrane, 9% had multiple pregnancy and 7% patient had hypertension. Cerebral pathology was found 28 and 31 cases by Craniosonogram and CT scan respectively. Germinal matrix hemorrhage/IVH (Intra ventricular hemorrhage) found 7(17.5%) in USG and 4(10.0%) in CT scan. Hypoxic ischaemic changes with mild ventriculomegaly observed 5(12.5%) in USG and 7(17.5%) in CT scan. Hypoxic ischaemic change found 4(10.0%) in USG and 5(12.5%) in CT scan. In USG evaluation of 28 patients having cerebral pathology & 16(72.7%) had in preterm group and 12(66.7%) in term group. In CT scan of brain 31 patients with cerebral pathology & 15(37.5%) in preterm group and 16(40.0%) in term group. CT scan found cerebral pathology 77.5% (31/40) cases and USG found 70.0% (28/40), with Kappa value was 0.551, which indicates that fair agreement between USG and CT scan for detection of cerebral pathology in respondent.

Abstract
FTIR spectra of 12CO adsorbed on poly(vinylpyrrolidone) (PVP)-stabilized colloidal platinum at room temperature were acquired and studied. Two new bands, at 2021 cm-1 and 1994 cm-1, were observed for the first time and were assigned to the stretching vibrations of CO linearly adsorbed on the Pt surface at edge and corner sites, respectively. The relative intensities of these two bands were found to vary with the coverage of CO, where the smallest particles showed the highest intensity, corresponding to the relative quantities of edge and corner sites per unit surface. The vibrational spectra signals reported for terrace sites on colloidal Pt red-shifted as the particle size was decreased, which showed the electronic interactions between the Pt surface and PVP, with PVP acting as an electron donor.

Abstract
Hypertension (HTN) is an important cause of cardiovascular mortality and the prevalence of hypertension is increasing particularly in middle- and low-income countries including Bangladesh. No data are available for the prevalence of hypertension among the government employees in Bangladesh. In this cross-sectional study, conducted from 30 October to 31 December 2016, 1219 government employees aging ≥18 years working in Rangpur city were evaluated for the presence of HTN and its risk factors. Socio-demographic and anthropometric data, data on the presence of various known risk factors of hypertension were collected. Hypertension was defined with systolic BP ≥140mmHg and/or diastolic BP ≥90mmHg or those getting treatment for hypertension. Statistical analysis was done by using SPSS version 23.0; odds of hypertension among subjects with risk factors were calculated and p ≤0.05 was considered to be statistically significant. The prevalence of hypertension was 38.3% among the study subjects. Significantly higher odds of having hypertension were observed in study subjects with the age groups of 35-49 (OR 2.12, 95% CI: 1.51-2.99, p<0.001) and ≥50 (OR: 4.96, 95% CI: 3.43-7.18, p<0.001) years than age group <35 years. Employees who were averagely satisfied and not satisfied for their jobs also had higher odds (OR: 1.38, 95% CI: 1.00-1.91, p=0.049 and OR: 1.48, 95% CI: 3.43-7.18, p=0.337) of having hypertension than fully satisfied ones. Having diabetes mellitus was found to increase the odds (OR 2.12, 95% CI: 1.51-2.99, p<0.001) of hypertension. Male gender, urban/suburban residence, not doing physical exercise, sedentary/light working habit, overweight/obesity also increased the odds of having hypertension though these were not statistically significant. There is a high burden of hypertension among the government employees in Rangpur city. Age, job satisfaction and diabetes were independent risk factors of hypertension.

Abstract
A solvent-free, low-cost, high-yield and scalable single-step ball milling process is developed to construct 2D MoS2/graphene hybrid electrodes for lithium-ion batteries. Electron microscopy investigation reveals that the obtained hybrid electrodes consist of numerous nanosheets of MoS2 and graphene which are randomly distributed. The MoS2/graphene hybrid anodes exhibit excellent cycling stability with high reversible capacities (442 mA h g−1 for MoS2/graphene (40 h); 553 mA h g−1 for MoS2/graphene (20 h); 342 mA h g−1 for MoS2/graphene (10 h)) at a high current rate of 250 mA g−1 after 100 cycles, whereas the pristine MoS2 electrode shows huge capacity fading with a retention of 37 mA h g−1 at 250 mA g−1 current after 100 cycles. The incorporation of graphene into MoS2 has an extraordinary effect on its electrochemical performance. This work emphasises the importance of the construction of the 2D MoS2/graphene hybrid structure to prevent capacity fading issues with the MoS2 anode in lithium-ion batteries. A solvent-free, low-cost, high-yield and scalable single-step ball milling process is developed to construct 2D MoS2/graphene hybrid electrodes for lithium-ion batteries.![]()

Abstract
Reconstruction of total lip is a challenging task for a plastic surgeon. It becomes more complicated when there is loss of additional tissues like angle of mouth, buccal mucosa or floor of the mouth. Radial forearm flap with palmaris longus tendon provides an easier but reliable technique for three dimensional lip reconstructions with good functional and aesthetic outcome. In this short observational series we included 5 patients of total lip reconstruction and conducted at Sylhet MAG Osmani Medical College Hospital and Private Clinic of Sylhet, Bangladesh from January 2014 to December 2017. Among these one was a case of basal cell carcinoma of upper lip and rest was squamous cell carcinoma of lower lip. The mean age was 71 years. All the flaps survived and patients had normal speech and oral continence. Composite radial forearm flap with palmaris longus tendon is a good, reliable option for total lip reconstruction.

Abstract
Distal humeral fractures are relatively rare injuries that constitute approximately 2% of all fractures which occur due to high energy trauma in young males. Because they involve the articular surface and usually cause an instable elbow, surgical treatment is necessary for the recovery of elbow functions in the majority of cases. The principles of absolute stabilization and early mobilization in the elbow are of more importance than in any other joint. As the AO classification, nonunion and implant loosening is more common in type C fractures of the distal humerus involving the joint surface. Aim of this prospective study was to evaluate the outcome of "Double Tension Band wiring" method for the treatment of intercondylar fractures of humerus and was conducted in a tertiary hospital of Bangladesh from July 2017 to June 2019. Twenty five patients, all presenting with fresh fractures of the distal humerus, treated with double tension band wiring. These patients were prospectively evaluated over a period of at least 6 months. Fractures were classified according to Jupiter classification and AO classification of distal humeral fractures. Due to AO classification, total fractures were C1 fractures. Average age of the patients was 56.20 years (32-70 years). There were 20 males and 5 females. Out of 25 cases treated with this method, rigid fixation and union was achieved in all of them. The average tourniquet time was 69 minutes range was minimum 50 minutes and maximum 120 minutes. Radiological union was achieved at an average of 14.2 weeks (10-18 weeks). Average range of motion was 112.8 degrees (107-116). Excellent to good results were seen in almost 86% of cases as per the Mayo Elbow performance score at 6-month follow-up. Wound infection had been occurred in 2(8%) cases, ulnar nerve neuropathy had been occurred in 1 case, delayed union of olecranon process of ulna had been occurred in 1(4%) case, implant failure had been occurred in 2(8%) cases, heterotrophic ossification had been occurred in 2(8%) cases, varus valgus instability had been occurred in 1(4%) case, gun stock deformity had been occurred in 2(8%) cases. Double tension band wiring is a reliable, less demanding and cost effective method of fixation of intercondylar fractures of humerus.

Abstract
Uropathogenic Escherichia coli is frequently resistant to different antibiotic leading to a critical condition of the patients. The purpose of the present study was to see antibiotic resistance pattern and genetic characteristics of ESBL and Carbapenemase-producing Escherichia coli. This cross sectional study was conducted in the Department of Microbiology at Mymensingh Medical College, Mymensingh, Bangladesh from October 2014 to December 2015. Patients presented with clinically diagnosed urinary tract infection at any age with both sexes who attended in the OPD of Mymensingh Medical College Hospital and the Doctors Diagnostic Centre in Mymensingh, Bangladesh was selected as study population. Non duplicate clinical isolates from urine were collected in full aseptic precaution for culture of bacteria. Escherichia coli were confirmed by PCR Stargetingadk. Antimicrobial susceptibility was measured by broth microdilution test. Minimum inhibitory concentrations against 18 antimicrobial agents were measured. Beta-lactamase genes were detected by multiplex PCR. For all the isolates showing resistance to imipenem and/or meropenem, presence of carbapenemase genes was confirmed by multiplex/uniplex PCR using primers. A total of 233 non-duplicate clinical isolates of Escherichia coli were collected from patients of which dominant phylogenetic group was B2 which was 78(33.5%) isolates of which 71 isolates were B2a and 7 isolates were B2b. Furthermore, Group A was in 29.6% isolates and Group D was in 26.6% isolates. E. coli showed significantly higher resistance rates to piperacillin, cephalosporins, and some other antimicrobials. Meropenem-resistance was detected in 8.2% of E. coli. The detection rate of blaTEM was 41.6% in E. coli. Carbapenemase genes were detected in 9(3.9%) isolates of E. coli and identified as genes encoding NDM-1, -5, and 7 and OXA-181. All the blaNDM-positive E. coli isolates carried also blaCTX-M-15, except for a group B1 isolate. E. coli is significantly higher resistance rates to piperacillin, cephalosporins, and some other antimicrobials and possesses different ESBL and carbapenemase genes.

Abstract
Bacterial communities strongly influence the digestion, health and immune status of fish. This study investigates the microbial distribution of the anterior, middle and distal gut sections of three economically important carp species in Bangladesh, rohu, catla and mrigal (commonly known as Indian major carps), using 16S rRNA-based Illumina sequencing technology. The alpha-diversity measurement with one-way ANOVA indicated high species richness, Shannon and Simpson indices in the middle and distal gut, while the anterior gut of IMCs had the lowest diversity. At the phylum level, there was high abundance of Proteobacteria in the GITs of rohu and mrigal, whereas Fusobacteria was dominant in the anterior and middle guts of catla. At the genus level, diverse microbial communities were identified across the three GIT sections, with six indicator genera found in rohu, catla and mrigal, as revealed by linear discriminant analysis (LDA) at a 0·05 level of significance. Of the 218 genera identified, only 33 were common across the anterior, middle and distal guts of all three species. Bacterial diversity was significantly higher (P < 0·05) in mrigal, followed by catla and rohu, respectively. Alongside the common bacteria Aeromonas, Enterobacter and Serratia, the overwhelming abundance of Cetobacterium, Shewanella and Plesiomonas warrants further investigation. SIGNIFICANCE AND IMPACT OF THE STUDY: This study investigates the microbial communities of the gastrointestinal tracts (GITs) of three Indian major carp (IMC) species-rohu, catla and mrigal, obtained from a polyculture pond under the same feeding regime. Diverse microbial communities were found, with significantly different relative abundances and diversities of phyla and genera. The results provide valuable information on GIT microbial communities that may be useful for nutrition and health management in IMCs.

[PMID: 31867464 PMCID: PMC6906666 DOI: 10.1016/j.heliyon.2019.e02994] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2019] [Revised: 10/10/2019] [Accepted: 12/03/2019] [Indexed: 11/27/2022] Open
Abstract
The hybrid variety of Cucurbita maxima is commercially available and frequently used as food in Bangladesh compared to the native variety. Although the seeds of Cucurbita maxima have nutritional and therapeutic values, people in Bangladesh typically throw them away as waste. If we can explore their physicochemical and biochemical properties, this will add new knowledge to nutrition and food science. Thus, in this study, we compare the physicochemical and biochemical properties of native and hybrid varieties of pumpkin seed and seed oil. Solvent extraction methods were used to obtain oil. The physicochemical properties of the extracted seed oils were examined by titration methods and proximate compositions of pumpkin seeds were determined using the standard method. Tocopherols were analyzed by HPLC and fatty acids were identified by GC/MS as N-acylpyrolidines. The specific gravity, refractive index, viscosity, acid value, saponification value, iodine value and ester values were determined and among them iodine values and acid values were significant (p < 0.05) at native but saponification and ester values were very highly significantly (p < 0.001) at hybrid. The comparative lipid content in the seed of native variety was higher than hybrid (p < 0.01) and protein contents were higher but not significant. However, crude fiber content was higher in the hybrid (p < 0.01). There was no significant differences of moisture, ash, sugar and starch contents in between the two varieties. The total tocopherol, contents were very high (p < 0.001) in native. In hybrid, saturated fatty acids -capric acid, myristic acids were more (p < 0.001) but in native unsaturated fatty acid linoleic and linolenic acids were predominant (p < 0.05). Owing to the considerable differences in the physicochemical composition, the fatty acids and other properties, this study may suggest that the both varieties of pumpkin seed oil may be an alternative good source of edible oil.

Abstract
Although esthetic factors might limit by the presentation of materials used, all-metal complete cast crown should always be offered to patients requiring restoration of endodontically treated posterior tooth. The complete cast crown has the highest longevity of all fixed restorations. It could be used to rebuild a single tooth or a retainer for a fixed prosthesis. It involves all the axial walls as well as the occlusal surface of the tooth to be restored. All restorations are placed in the oral environment in contact with the gingival tissue. Thus clinicians must choose nontoxic or least toxic metal alloys, since any release of elements that might cause reactions. This study was designed to observe clinical responses of nickel chromium alloy and gold alloy cast crown and provide guidance to ascertain the best alloy for cast metal crown, which serves better functional restoration.

Abstract
Fibromatosis of mesentery is a very rare disease and only a few cases have been reported. Here we report a case of 40 year old man admitted on 16 October, 2017 in the Department of Surgery (Unit-3) of Mymensingh Medical College Hospital with history of recurrent abdominal pain and progressively enlarging intra-abdominal lump for 2 years. Out of different diagnostic dilemmas, finally we came to the conclusion of its being a mass lesion primarily arising from the mesentery and involving the adjoining gut according to the report of CT abdomen. Laparotomy was performed and a lump measuring about 18 cm × 20 cm arising from mesentery was found, in which distal part of jejunum and proximal part of ileum were embedded. The mass was excised with incorporated gut loops and histopathology report revealed fibromatosis of mesentery.

Abstract
The prevalence of seizures in individuals with Down Syndrome (DS) is higher than in the general population. Rates of epilepsy in DS range from 1-13%. Forty percent of individuals develop seizures before 1 year of age and another 40% develop in their thirties or later. Boys have an earlier age of onset. The prevalence of epilepsy increases with age. Types of seizures are: 47% partial seizures, 32% infantile spasms and 21% generalized tonic-clonic seizures. Sex distribution for epilepsy in children with DS varies. Males have a younger age at onset. Trisomy 21 is common among epileptic children with DS but mosaicism or translocation has also been documented. The mechanisms underlying the increased seizure susceptibility in DS have not yet been completely explained. Seizures in infancy may be due to inherent structural brain abnormalities, like fewer inhibitory neurons, abnormal cortical lamination, persistent fetal dendritic morphology, underdeveloped synaptic profiles. Concentrations of carbonic anhydrase II are increased in the brains of young children with DS. It potentially increases seizure susceptibility. The pharmacological treatment of epilepsy in DS is same as that of other patients diagnosed with epilepsy. Individuals with DS have an unusually high number of side-effects from phenytoin. The diagnosis, classification and treatment of epilepsy in DS follow the guidelines applied to the general population. Review of literatures from 1960 to 2017 and electronically identified articles on epilepsy in Down syndrome in children in English are searched from internet and pub med to describe features of seizures in children with DS.

Abstract
AIMS This study conducted bacterial community, virulence and antibiogram profiling inside the hindgut and skin of freshly caught hilsa fish and those sold at markets. METHODS AND RESULTS The results of 16S rRNA-based high-throughput sequencing showed a higher number of bacterial genera in marketed fish samples than in fresh fish samples. The total operational taxonomic units, genus counts and diversity index were significantly higher (P > 0·05) in marketed fish, which also had abundant pathogenic bacterial groups. Skin samples had a lower profusion of pathogenic bacteria than gut samples. A total of 52 bacterial isolates from nine species were identified in this study, of which 25 were from a Chittagong market and 22 were from a Dhaka market, whereas only five were from fresh hilsa. The polymerase chain reaction amplification of 12 species-specific virulence genes in the 52 isolates, namely, aer, hly, chxA, toxB, rtxC, sfa, uge, norB, trx, toxA, ipaH, sigA and coa, indicated a high number of positive samples containing Vibrio cholerae, Aeromonas spp., Klebsiella pneumoniae, Escherichia coli and Staphylococcus aureus. Antibiogram profiling of these bacteria against 10 commercial antibiotics showed high-resistance patterns of the isolates against sulfamethoxazole, kanamycin, neomycin, ampicillin and tetracycline. CONCLUSION The results reveal the spread of multidrug-resistant bacteria in hilsa fish marketed for human consumption in Bangladesh. SIGNIFICANCE AND IMPACT OF THE STUDY This study highlights the risk of spreading environmentally and clinically pathogenic bacteria in fish sold for human consumption in Bangladesh. Such bacteria come from aquatic pollution and poor handling, storage and transportation practices that may predispose fish to major outbreaks of infectious and waterborne diseases.

Abstract
Finite element method is a powerful technique for solving a wide range of engineering problems. However, the existence of the spurious solutions in full-vectorial finite element method has been a major problem for both acoustic and optic modal analyses. For emerging photonic devices exploiting light-sound interactions in high index contrast waveguides, this problem is a major limitation. A penalty function is introduced to remove these unwanted spurious modes in acoustic waveguides, which also identifies the acoustic modes more easily. Numerically simulated results also show considerably improved vector mode profiles. The proposed penalty method has been applied for the characterization of low index contrast single mode fiber and also for high index contrast silicon nanowire to demonstrate its effectiveness.

Abstract
Distal third comminuted humerus shaft fractures are challenging injuries to treat because of complex anatomy and fracture patterns. Functional bracing, operative treatment with intramedullary nails or conventional plates also has limitation of inadequate fixation in the distal third comminuted humerus shaft fractures. Locking compression plate (LCP) has been introduced to overcome this problem. Our aim of this study was to assess the effectiveness of osteosynthesis of distal third comminuted humerus shaft fractures by LCP using posterior approach. This prospective observational study was conducted from July 2015 to June 2018 at Mymensingh Medical College Hospital (MMCH) and National Institute of Traumatulogy & Orthopaedic Rehablitation (NITOR), Dhaka, Bangladesh. Thirty three patients were operated on for comminuted fractures of distal third humerus. Two cases were excluded from the evaluation of final out come due to their discontinued follow up. Treatment included open reduction and LCP fixation by posterior mid line approach. The range of motion of the shoulder and elbow were evaluated according to the criteria by modified Constant and Murley scoring system. Union was achieved in all the patients after a mean of 17 weeks (range 12-24 weeks). Deep infection, nonunion, malunion, implant failure or permanent nerve injury did not occur in any of the patients. Three patients had transient radial nerve palsy. Four patients developed superficial infections. All patients were relieved pain postoperatively. Shoulder range of motion was excellent in 20 patients & elbow range of motion was excellent in 21 patients. Functional out come were excellent in 11 & good in 16 patients which constituted 87% satisfactory results. Treatment with open reduction and LCP fixation by posterior approach is a safe and effective option in distal third comminuted humeral fractures.

Abstract
Preeclampsia is one of the most frequent complication of pregnancy which manifested by hypertension during pregnancy for the first time after 20th weeks of gestation with proteinuria. The aim of the study was to estimate the changes in serum calcium level in preeclamptic patients when compared with normal pregnant women. The case control study was carried out in the Department of Biochemistry, Mymensingh Medical College, Mymensingh, Bangladesh in collaboration with the Department of Obstetrics and Gynecology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2016 to June 2017. A total of 100 subjects were included. Among them 50 were subjects of preeclamptic patients as case and another 50 were apparently healthy normal pregnant women as control. The study revealed that serum calcium level was lower in preeclamptic women (case) as compared to healthy control subjects. The mean values of serum calcium levels were 7.63±0.42 and 8.12±0.94mg/dl in case and control group respectively. The difference in mean serum calcium were highly significant (p<0.001) when compared between case and control.

Abstract
Treatment of extra-articular distal humeral shaft fractures with plating techniques is often difficult. The recent development of LCP has improved the surgical treatment of fractures by overcoming the few drawbacks of older fixators. The aim of this prospective observational study was to assess the effectiveness of osteosynthesis of extra-articular diaphyseal fractures of the distal third of the humerus using a single locking compression plate (LCP) and was conducted from July 2016 to June 2018 at the National Institute of Traumatology and Orthopedic Rehabilitation (NITOR), Dhaka, Bangladesh. Thirty (30) patients with closed fracture distal 3rd extra-articular humeral shaft fractures were treated by open reduction and internal fixation by locking compression plate. Two cases were excluded from the evaluation of final outcome due to their discontinued follow up. Detailed clinical conditions of all patients, technical difficulty with the implant, postoperative hospital stay period were recorded. Patients were followed up at 2nd week, 4th week, then 4 weekly upto 6 months. The patients were evaluated clinically and radiologically for outcomes. The progresses of healing as well as occurrence of complications were recorded. The range of motion of the shoulder and elbow were evaluated according to the criteria by Rommens grading. Functional evaluation was made according to the criteria by Modified Constant and Murley Scoring System. Union was achieved in all the patients after a mean of 15 weeks (range 12-20 weeks). There were no complications like deep infection, nonunion, malunion, implant failure, or nerve injury occurs in any of the patients. Two patients had transient radial nerve palsy. Two patients developed superficial infection. All patients were relieved pain postoperatively. Functional outcome were excellent in 10 patients, good in 15 patients which constituted 89% satisfactory results. The study has shown that the LCP is an effective, dependable solution for the management of distal third diaphyseal fractures of the humerus.

Abstract
This cross sectional study was carried out in the Department of Radiology & Imaging, Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM), Dhaka, Bangladesh from July 2010 to June 2011 with a view to evaluate the diagnostic accuracy of refractory shadowing on transabdominal pelvic sonography for leiomyomas and in differentiating them from other pelvic masses. Histopathological examination of the surgically resected masses was taken as the standard diagnostic tool. A total number of 50 patients of pelvic masses were studied. It was observed that a pattern of sharp, discrete, shadow was typical of leiomyoma, which reduces diagnostic ambiguity. The mean age of the patients was 38 years. Mean size of the masses was 4.25±3.25cm. Taking histopathological examination as the Gold standard, accuracy of refractory shadowing on transabdominal sonography in diagnosis of leiomyoma was 65.1%. Specificity and sensitivity were 90.3% and 54.2% respectively. Positive predictive value was 92.9% and negative predictive value was 45.9%. Statistical analysis revealed strong association of refractory shadowing with diagnosis of leiomyomas (p<0.01).

Abstract
We examined the hypothesis that the cross mattress for chest drain insertion site security is better than that of polypropylene horizontal mattress in chest trauma patient required tube thoracostomy at the Department of Casualty Surgery, Dhaka Medical College Hospital, Dhaka, Bangladesh from January 2016 to June 2016. Accordingly we prospectively studied 50 consecutive patients who needed chest tube insertion. In 25 consecutive cases chest drain insertion site was secured with polypropylene horizontal mattress technique (Control- Group A) and another 25 consecutive patients had a cross-mattress with non-absorbable suture materials (Experimental- Group B). All chest tubes were inserted into the triangle of safety to following the BTS guideline. A baseline x-ray chest was compared with post-procedure chest x-ray. Male preponderance and young adults were comprised in both the groups; mean age in Group A and Group B was 38.7±15.5 and 37.3±14.1 respectively. Haemo-pneumothorax was the most common cause of tube thoracostomy among the trauma victims. This study shows that, polypropylene horizontal mattress results in increased chest tube site infection 52% in Control Group vs. 12% in Experimental Group (p=0.002). Although there was similar incidence of blood loss between the groups, the length of Hospital stay was significantly higher in Control Group. We conclude that cross mattress for chest drain insertion site security showed a better clinical outcome, less wound complications and less hospitalization.
