Abstract
Alzheimer's disease (AD) is a dynamic degeneration of the brain with progressive dementia. Considering the uncertainties in its molecular mechanism, in the present study, we employed network-based integrative analyses, and aimed to explore the key molecules and their associations with small drugs to identify potential biomarkers and therapeutic agents for the AD. First of all, we studied a transcriptome dataset and identified 1521 differentially expressed genes (DEGs). Integration of transcriptome data with protein-protein and transcriptional regulatory interactions resulted with central (hub) proteins (UBA52, RAC1, CREBBP, AR, RPS11, SMAD3, RPS6, RPL12, RPL15, and UBC), regulatory transcription factors (FOXC1, GATA2, YY1, FOXL1, NFIC, E2F1, USF2, SRF, PPARG, and JUN) and microRNAs (mir-335-5p, mir-26b-5p, mir-93-5p, mir-124-3p, mir-17-5p, mir-16-5p, mir-20a-5p, mir-92a-3p, mir-106b-5p, and mir-192-5p) as key signaling and regulatory molecules associated with transcriptional changes for the AD. Considering these key molecules as potential therapeutic targets and Connectivity Map (CMap) architecture, candidate small molecular agents (such as STOCK1N-35696) were identified as novel potential therapeutics for the AD. This study presents molecular signatures at RNA and protein levels which might be useful in increasing discernment of the molecular mechanisms, and potential drug targets and therapeutics to design effective treatment strategies for the AD.

Abstract
This cross sectional descriptive study was performed on 70 postmortem vermiform appendix (male 34 and female 36) to find out the external diameter of vermiform appendix of Bangladeshi people in different age and sex. The specimens were collected from autopsy laboratory of the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh, Bangladesh from October 2016 to March 2017 by purposive sampling technique. 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 techniques. The vermiform appendix was collected and preserved in 10% formol-saline solution. The external diameter of vermiform appendix was measured with the help of digital slide calipers. Three measurements were taken at its base, middle and near the tip (1cm away from the tip) and expressed in mm. The data were analyzed by using student unpaired 't' test and compaired with the findings of other national and international studies and standard text books. It was observed that external diameter of vermiform appendix gradually decreased as age advanced. The mean±SD external diameter of vermiform appendix at base was 6.50±0.82 mm, 6.22±0.60 mm, 6.00±0.51 mm and 5.51±0.57 mm in Group A, B, C & D respectively. The mean±SD external diameter of vermiform appendix at middle was 6.09±0.89 mm, 5.67±0.65 mm, 5.38±0.59 mm and 4.95±0.76 mm in Group A, B, C and D respectively. The mean±SD external diameter of vermiform appendix near the tip (1 cm away from the tip) was 5.73±0.88 mm, 5.21±0.72 mm, 4.81±0.74 mm and 4.34±0.74 mm in Group A, B, C and D respectively. Statistical analysis shows that the mean differences of external diameter of vermiform appendix at its base between Group A&D, B&D were statistically moderately significant at p<0.01 level. Between Group C&D was statistically significant at p<0.05 level and between Group A&B, B&C, A&C were statistically non significant at p = or >0.05 level. Mean differences of external diameter of vermiform appendix at its middle between Group A&D, B&D were statistically moderately significant at p<0.01 level. Between Group A&C was statistically significant at p<0.05 level and between Group A&B, B&C, C&D were statistically non significant at p = or >0.05 level. Mean differences of external diameter of vermiform appendix near its tip (1 cm away from the tip) between Group A&D was statistically highly significant at p<0.001 and mean differences between Group B&D, A&C were statistically moderately significant at p<0.01 level. Between Group A&B was statistically significant at p<0.05 level and between Group B&C, C&D were statistically non significant at p = or >0.05 level. Mean external diameter of vermiform appendix in male was higher than that of female in all age group at its base, middle and near the tip (1cm away from the tip) but mean difference between sexes in the different study groups was statistically non significant at p = or >0.05 level. The present study will help to increase the information pool on the external diameter of vermiform appendix of Bangladeshi people.

Abstract
Pediatric myocardium is unique from mature myocardium; thus, the use of adult cardioplegia for pediatric cardiac operations may provide suboptimal myocardial protection. It is found that children undergoing heart surgery show evidence of less myocardial damage when del Nido cardioplegia is used instead of a standard cardioplegic solution. Del Nido cardioplegia solution provides a depolarized hyperkalaemic arrest lasting up to 60 minutes, reduces spontaneous and inducible activity during arrest, and prevents hyper contraction during early reperfusion. In this single blind randomized trial, a total of 60 patients underwent intra cardiac repair for TOF in National Institute of Cardiovascular Diseases, Dhaka, Bangladesh from July 2014 to January 2016 fulfilling inclusion and exclusion criteria. They were randomly assigned in two groups- 30 patients in Del Nido group (Group A) and 30 patients in standard group (Group B). Comparison between groups was done by Chi square test and Student's test. All data were analyzed by SPSS 20.0 for windows. P value less than 0.05 was considered as significant. There was statistically significant difference among the patients in terms of mean total initial cardioplegia volume, mean number of additional dose, mean additional dose amount, mean cross clamp time, mean CPB time (331.67±188.07 vs. 458.67±226.62, p=0.022; 0.13±0.35 vs. 1.27±0.89, p=0.000; 23.33±60.76 vs. 336.83±259.6, p=0.000; 45.10±10.35 vs. 59.23±23.21, p=0.003; 89.30±15.73 vs. 111.10±29.23, p=0.001 respectively). Mean post operative serum troponin I level at arrival in ICU and after 24 hours between two groups were statistically significantly different (55.60±32.91 vs. 83.5±58.99; p=0.024 and 13.01±5.84 vs. 18.16±9.51; p=0.014 respectively). The mean ventilation duration, mean ICU stay were also statistically significant. This study showed that cardiac arrest with Del Nido cardioplegia during intra cardiac repair for TOF was associated with improved myocardial protection over standard cardioplegia in terms of reduced CPB and cross clamp times, lower total volume of cardioplegia.

Abstract
Injuries are a focus of public health practice because they pose a serious health threat, occur frequently and are preventable. The evidence regarding injury, its contributing factor and its consequence in rural population of Bangladesh is scarce. Present study aimed to assess the epidemiology of injury in a rural area. The study was conducted in the 'Bairag' Union of Anwara upazilla in Chittagong district of Bangladesh. Data of 6256 individuals were collected from 1016 households. Three structured and standardized questionnaires were used for data collection. The questionnaires were pretested and validated prior to final survey. Severity of injury was assessed based on the number of days with restricted activity and consequences of injury were considered as a measure of severity of injury. A total of six people died due to injury in last one year in the survey, the death tolls to 0.096% (95% CI 0.037%-0.199%). A total of 392 experienced an injury that at least hampered one day's routine activity. Crude prevalence of injury over last one year is calculated to be 6.27% (95% CI 5.69%-6.89%). Of injured subject's majority (77.2%) were aged between 10 to 59 years, 73% were male, 55.6% were of lower class and among them 7.9 % suffered multiple injuries. More than 80% of the incident leading to injury happened during the day, (8 am to 6 pm). Daytime injury mostly occurs in afternoon. The mechanism of injury of 30% subjects were road accident, of 29.5% subjects was slip, trip or fall. In 17.9% victims' mechanism of injury was collision with a person or object. Around 10% had deep cut, 1.4% had superficial cut, and 3.3% patient had burn through contact with heat. Among the injured only 19.2% escaped any physical consequence, 27.2% suffered from decrease in work capacity, 48.1% developed temporary disability, 3.8% developed permanent disability, and 1.2% suffered disfiguration.

Abstract
Carcinoembryonic antigen (CEA) is well established tumor marker for colorectal cancers worldwide. Recent studies show that serum prolactin level is also raised in colorectal cancers. The purpose of the study is to evaluate the correlation of serum CEA and Prolactin with Dukes' staging of colorectal carcinomas. Between January 2013 and June 2013, Serum CEA and Serum Prolactin were measured by radioimmunoassay from 103 patients who were histopathologically diagnosed as colorectal carcinomas. Evaluation of the stages of the colorectal cancers was done on the basis of preoperative investigations and postoperative histopathology and correlated with Preoperative Serum CEA and Serum Prolactin. Results were presented as median value, range and percentage. Male to female ratio was 1.4:1 with median age of 42.26 years (range 17-78 years). Most of the patients in this series presented with carcinoma rectum (42%). Most of the patients (52%) were found in Dukes' stage C and 27% and 15% cases were found as Dukes' stage B and Dukes' stage D respectively. Stage of the disease is directly proportionate to percentage of the patient with high serum prolactin except early stage (Dukes' A-50%, Dukes' B-28.6%, Dukes' C-33.3% & Dukes' D-46.7%). Similarly serum CEA level is directly proportionate to tumor stage (Dukes' A-0%, Dukes' B-32%, Dukes' C-40.7% & Dukes' D-74.7%). A preoperative high serum CEA value suggests advanced disease either locally or with distant metastasis. In contrast preoperative high serum prolactin (hyperprolactinaemia) did not suggest advanced disease as it can be elevated even in early stage of disease. Serum CEA and Serum Prolactin both are valuable tumor markers but serum CEA could not be replaced by serum Prolactin. Serum Prolactin may be a helpful marker in earlier stages of the colorectal cancer.

Abstract
Non Hodgkin's lymphomas (NHL) constitute a heterogeneous group of neoplasm of the lymphoid system. There are many histological subtype of NHL based on WHO classification of hematopoietic and lymphoid neoplasm. This cross-sectional study was carried out in the department of Pathology, Dhaka Medical College, Dhaka from January 2009 to December 2010 to observe the different subtypes of NHL using immunohistochemistry (IHC) with CD3. A total of 50 microscopically diagnosed case of NHL irrespective of age and sex were included in the study. The diagnostic morphologic criteria of each lymphoma subcategory were compiled and diagnosis was made. Mean age of the study subjects were 42.0±19.7 years with range 3-75 years and male female ratio was 1.8:1. Nodal NHL was 66% and extranodal cases were 34%. Maximum number of histolgic subtypes belonged to diffuse large B-cell lymphoma (DLBCL) and male was predominant in all histological subtypes, except peripheral T-cell lymphoma (PTCL). DLBCL was predominant in all B-cell NHL whereas PTCL was predominant in all T-cell NHL. The most childhood patients belonged to lymphoblastic lymphoma. Regarding cell lineage B-cell NHL was more common than T-cell NHL (88% vs. 12%), but high grade pattern was more predominant in T-cell type (83.3% vs. 65.9%). Among 50 study subjects histological (H & E) diagnosis reveals 46 cases as B-cell NHL and 4 as T-cell NHL but IHC confirms 6 cases as T-cell NHL.

Abstract
National Malaria Control Program (NMCP) of Bangladesh has introduced Artemisinin Based Combination (ACT), Coartem(R) (Artemether-Lumefantrine (AL), fixed dose combination, in the confirmed cases of uncomplicated P. falciparum malaria since 2004. Despite the reduction of mortality due to malaria, the development and spread of anti-malarial drug resistance wordwide posing a threat to the health services and will make it difficult to control malaria in Bangladesh in future. We need to have an alternative to Coartem which could be Artesunate-amodiaquine (AA) in a fixed dose combination (FDC), a cheaper altenative not yet evidenced to be effective and safe to our population. In this study we compared the efficacy and safety of Artemether + Lumefantrene (FDC, Coartem®) with Artesunate +Amodiaquine tablets (100/270 mg FDC) for the treatment of uncomplicated P. falciparum malaria in three high risk multi-drug resistant malaria prevalent areas of Bangladesh. It was an open label randomized controlled trial conducted between December 2008 and November 2009 in 4 upazillas in patients over the age 12 to 60 years diagnosed as a case of uncomplicated P.falciparum malaria. The outcome of the cases were measured as clinical response, parasitological response, defervescence time and parasite clearance time. Drug safety was assessed by comparing the adverse events. A total of 252 cases were randomized to receive Artesunate + Amodiaquine (AA group, 147 cases) and Artemether + Lumefantrene (AL group, 106 cases), one lost to follow up at day 28 in AA group. The distribution of the cases was comparable by age, sex and study sites. Treatment success response was observed 100% in the AL group and AA group had 99%, two failures with AA were late treatment failures and the difference was not statistically significant (p>.1). The parasitological sensitive (S) response was observed in 97% of cases in AL group and 95% in the AA group, and was not a statistically significant difference. There was no significant difference in deffervescence time and parasite clearance time between two groups of cases. No serious adverse events were observed. The frequencies of minor adverse events were insignificantly different between the two treatment groups. The two ACT regimen, AA and AL had no significant difference in efficacy and safety for treatment of Uncomplicated Malaria in Bangladesh. However, there were few more failures with AA regimen compared to AL regimen, which was not statistically significant. Both these regimens can be used alternatively by the NMCP of Bangladesh as first-line treatment option.

Abstract
An experiment was conducted to evaluate the efficacy of porcine follicle stimulating hormone (pFSH) dosage based on body weight (BW) on ovarian responses of crossbred does. Thirty donor does were divided into 3 groups getting pFSH dosages of 3, 5, and 8 mg pFSH per kg BW, respectively, and were named as pFSH-3, pFSH-5 and pFSH-8, respectively. Estrus was synchronized by inserting a controlled internal drug release (CIDR) device and a single injection of prostaglandin F2α (PGF2α). The pFSH treatments were administered twice a day through 6 decreasing dosages (25, 25, 15, 15, 10, and 10% of total pFSH amount; decreasing daily). Ovarian responses were evaluated on Day 7 after CIDR removal. After CIDR removal, estrus was observed 3 times in a day and pFSH treatments were initiated at 2 days before the CIDR removal. All does in pFSH-5 and pFSH-8 showed estrus signs while half of the does in pFSH-3 showed estrus signs. No differences (p>0.05) were observed on the corpus luteum and total ovarian stimulation among the treatment groups, while total and transferable embryos were higher (p<0.05) in pFSH-5 (7.00 and 6.71) than pFSH-3 (3.00 and 2.80) and pFSH-8 (2.00 and 1.50), respectively. In conclusion, 5 mg pFSH per kg BW dosage gave a higher number of embryos than 3 and 8 mg pFSH per kg BW dosages. The results indicated that the dosage of pFSH based on BW is an important consideration for superovulation in goats.

Abstract
American Diabetic Association (ADA) affirms HbA1c with cut off value of 6.5% as a diagnostic criteria of diabetes mellitus. World Health Organization (WHO) also supports but recommended that a value <6.5% does not exclude diabetes which is diagnosed by glucose test. The aim of this study was to evaluate the diagnostic efficacy of HbA1c in terms of sensitivity, specificity, positive and negative predictive value and accuracy in a selected group of Bangladeshi subjects. This cross-sectional study included 761 adult Bangladeshi subjects of both sex attending the outdoor in a tertiary healthcare center during the period of September 2009 to September 2010. Fasting, postprandial (2 hours after glucose load) plasma glucose and HbA1c were measured. Diabetes is defined according to HbA1c and plasma glucose. Sensitivity, specificity, positive and negative predictive value of HbA1c were 90.00% (CI 86.48-92.86%), 76.21% (CI 71.68-80.35%), 78.17% (CI 73.94-82.00%) and 88.96% (CI 85.10-92.10%) respectively. Accuracy was 82.92% with odds ratio (OR) 28.84 (CI 19.10-43.54%); p < 0.001. Though HbA1c revealed remarkable diagnostic efficacy and ease of performance, still it can not over rule the role of plasma glucose in diagnosis of diabetes mellitus.

Abstract
A modification of Friedewald's formula to estimate serum low-density lipoprotein cholesterol (LDLC) up to serum triglyceride (TG) level of 11.3 mmol/L in Bangladeshi population has recently been published. The aim of this study was to compare the modified formula with direct measurement of LDLC in Bangladeshi population in a different setting. One thousand and fifty two specimens from adult subjects were analyzed. Serum total cholesterol (TC), high-density lipoprotein cholesterol (HDLC), LDLC and TG were measured by standard methods. The modified Friedewald's formula was applied to estimate LDL cholesterol concentration. Results were expressed as mean ± SD and calculated LDLC was compared with measured LDLC by two-tailed paired t test, Bland-Altman plot for absolute bias, Pearson's correlation coefficients of calculated LDLC with measured LDLC and Passing & Bablok regression equation of calculated LDLC against measured LDLC. The mean ± SD of measured LDLC was 2.98 ± 0.82 mmol/L. LDLC calculated by modified Friedewald's formula was 2.77 ± 0.86 mmol/L. The mean absolute bias was -0.20 ± 0.32 mmol/L, Pearson's correlation coefficient (r) was 0.9293 (P < 0.0001) and Passing & Bablok regression equation was y = - 0.3856+1.0597x for modified formula up to serum TG ≤ 11.3 mmol/L. Compared to original Friedewald's formula, performance of the modified Friedewald's formula was better up to serum TG ≤ 4.52 mmol/L. The study reveals that the modified Friedewald's formula may be used to calculate LDLC approximately in Bangladeshi population.

Abstract
Non alcoholic steatohepatitis is a hepatic disorder with histological features of alcohol induced liver disease that occurs in individual who do not consume significant alcohol. Liver biopsy is an important part of the evaluation in term of both grade & stage. A cross sectional study was carried out in the department of Pathology, Dhaka Medical College, Dhaka & department of Hepatology, Bangabandhu Sheikh Mujib Medical University (BSMMU) from July 2007 to June 2009. Total 55 adult subjects of both sex were included on the basis of predefined inclusion & exclusion criteria in this study to evaluate the histological pattern of non alcoholic fatty liver disease (NAFLD) and its correlation with risk factors. Liver biopsy was done and H & E and Masson's Trichrome stain slides were examined to evaluate the grade and stage of NAFLD. Scoring and semiquantitative assessment of steatosis and NAFLD severity was done according to Kleiner scale known as NAFLD activity score (NAS). The results of Pearson correlation showed only BMI and triglyceride level significantly correlated with NAS score. The results of Spearman's rank correlation showed that BMI, central obesity, triglyceridaemia and age significantly correlated with staging of fibrosis. The results of multiple regression analysis showed that variation of NAS depend on BMI and triglyceride level. The study also revealed that risk factors contributed about 29% risk for the occurrence of non alcoholic steatohepatitis.

Abstract
Land cover change is a widespread and prominent feature in Bangladesh. It is more energetic in the South-west coastal region such as Khulna and Satkhira region. The research was completed by 30 years (1980 to 2009) by using four Landsat satellite images (1980, 1989, 2002 and 2009). During research it was originated that the main classes of changes were homestead, fallow land, water bodies and mangrove vegetation in the study area. The most imperative change was observed in fallow lands (the types of cultivable lands with or without any standing crops and also uncultivable lands). Fallow land was decreased, concerning 2,259 sq km in 2009 which land was 3,867 sq km during in 1980. It was dropped 49% to 29% of total study area between the years of 1980 to 2009. The water bodies were increased about 10% in those 30 years, regarding 14% to 24%. The total water bodies covered 1140 sq km at 1980 which was increased 1851 sq km during 2009 in the study area. The sea-level rise, increasing salinity and availability of less fresh water are responsible for inland intrusion of saline water and creating favorable environment for shrimp farming in the region. As a result farmers are converting fallow lands to shrimp farming which is economically very beneficial. Important agricultural and non-agricultural lands also converted by homestead intended for increasing population of Bangladesh. There was only 398 sq km (only 5%) area covered by homestead during 1980. But the homestead covered area was increased about 1490 sq km (19%) at 2009. So, compared to the last 30 years 14% homesteads land cover areas are increased. There was not any astonishing changed in mangrove vegetation. Some mangroves areas were shattered and some other mangroves were full-fledged again in delta areas. The harmful land cover changes are not expectable for the natural environment. But it transpires by many natural and anthropogenic tricks now a day. So, the authority should seize initiatives to protect this category of catastrophe.

Abstract
Sundarban is the largest mangrove wetland in the world. It covers an area of about 1mha, of which 60% is located in Bangladesh and the remaining western portion, comprising 40%, lies in India. Mangrove ecosystems are of great ecological significance in the tropical and sub-tropical coast. They protect our coast from heavy wind, tidal waves, coastal erosion and sea water intrusion, generate substantial quantities of fishery resources and provide many useful forestry products. The Sundarban ecosystem supports rich fisheries diversity. This ecosystem support 27 families and 53 species of pelagic fish, 49 families 124 species of demersal fish, 5 families and 24 species of shrimps, 3 families and 7 species of crabs, 8 species of lobster. A total 334 plants, 165 algal, 13 special orchids, 17 fern, 87 monocotyledon and 230 dicotyledon belonging to 245 genera and 75 families from the sundarbans and adjacent area are found available. The principal tree species is Sundry (Heritiera fomes) which covers about 73% to total landmass and the second species is Gewa (Excoecaria agallocha) which covers about 16% of total forest area. The plant species include 35 legumes, 29 grasses, 19 sedges, and 18 euphorbias. Of the 50 true mangrove plant species recorded throughout the globe, the Sundarbans alone contain 35 species. The magnificent among the animals on land is Royal Bengal Tiger, Spotted deer, barking deer and wild boars are there in plenty. Besides those jungle cats, fishing cat, civet cat, monkey, bengal fox, jackle, water monitor, monitor lizard and snakes are important faunal spp. Moreover, abundant of the Sundarbans are purple heron, pond heron, cattle egret, little egret, open billed stork, smaller adjutant stork, brahmini kite, spotted dove, rose ringed parakeet, crow pheasant, wood pecker, bee eater, drongo, pide myna, jungle myna, bulbul, tailor bird, magpie robin, sparrow etc., Otherwise, recorded that wild Buffalo, 2 species of deer, javan rhinoceros extinct and presently 2 species of amphibians, 14 species of reptiles 25 species of birds and 5 species of mammals are considered as endangered species. This paper is to produce a new assessment of the mangroves ecology of Sundarbans. DOI: http://dx.doi.org/10.3329/jsf.v8i1-2.14618 J. Sci. Foundation, 8(1&2): 35-47, June-December 2010

Abstract
We conducted a study of the knowledge, attitudes and practices regarding dog bites among residents of a rural community in Bangladesh from September 2006 to February 2007 using face to face interviews with 1,973 adults from five villages. The mean age of the respondents was 34+/-16 years. Sixty-eight percent of subjects were female, 7.3% of respondents reported a history of dog bite in a family member; 10% had been bitten twice. Sixty-five percent of subjects were aware of rabies and 99.1% knew a dog bite was the cause of rabies. Seventy-one percent of subjects were aware of a rabies vaccine, 77.5% of respondents stated rabies can cause death. Ninty percent of dog bite victims received treatment by traditional healers, 25% were treated with a rabies vaccine and 2.1% of victims died. Greater awareness is needed in rural Bangladesh regarding prevention of rabies.

Abstract
Halima, a 7 years old female child was admitted initially in the Department of Neurosurgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbagh, Dhaka, Bangladesh with the complaints of burning sensation in the neck for last four month. Initially pain was mild and gradually it became severe and agonizing at night which awakening her from sleep. Following fifteen days of admission, her left hand gradually became weak and numb. Subsequently, all four limbs became involved within one month. Magnetic resonance imaging (MRI) showed expansion of cervical cord with hypo-intense in T1 and inhomogeneous hyper-intense in T2 areas with widening of cervical canal. Post gadolinium diethylene triamine penta-acetic acid dimeglumine (Gd-DTPA) films showed mild heterogeneous contrast enhancement of the cord at the C2-C4 level. The cervical disc showed normal signal intensity on T2WI. During surgical procedure, laminectomy was done at C1-C5 level to release compression and dura matter was opened. Biopsy from involved tissue was taken and sent for histopathological examination and reported as embronal rhabdomyosarcoma. Immunohistochemistry (IHC) of tumor showed negative reaction for desmin, focal positivity for pancytokeratin and positivity for S-100 protein. The tumor was then diagnosed as atypical meningioma,intradural-intramedullary (WHO grade-II). Then, following transfer to the Department of Pediatric Hematology and Oncology, BSMMU, protocol based chemotherapy was started followed by subsequent radiotherapy. The child was gradually improving after decompression of dura matter, commencement of chemotherapy and following external beam radiotherapy. So, an awareness of varied clinical manifestation of atypical meningioma of intrdural-intramedullary spinal cord tumor should be suspected to establish a correct diagnosis when the presenting signs and symptoms are enigmatic, presenting with intractable burning sensation or pain in the neck and investigation should be done accordingly.

Abstract
The clinical entity 'Wandering spleen' is an uncommon presentation and it is more often diagnosed in children than in adults, mostly women of reproductive age. Here is a case of a young woman who presented with generalized weakness and fever, and a painless mobile lump in her central abdomen. The laboratory evaluation revealed a haemolytic state and Haemoglobin electrophoresis showed β-Thalassemia trait (Hb A2 5.1%). Ultrasonography and Computerized Tomography (CT) scan confirmed that the mass is spleen and spleen is not present in its normal anatomical location. Abdominal CT described a well-defined, homogenous pediculated mass with echo texture comparable to spleen. Radioisotope scanning could be used as an alternative for confirmation of diagnosis of this rare condition, but was not done in our case. Colour Doppler sonography of the splenic circulation revealed no infarction and intact splenic vasculature. Wandering spleen should be considered in the differential diagnosis of idiopathic abdominal or pelvic lumps. The authoritative opinion for the treatment of such a case is splenectomy or splenopexy especially in children and here, in this case splenectomy was done.

Abstract
BACKGROUND Most malaria deaths occur in rural areas. Rapid progression from illness to death can be interrupted by prompt, effective medication. Antimalarial treatment cannot rescue terminally ill patients but could be effective if given earlier. If patients who cannot be treated orally are several hours from facilities for injections, rectal artesunate can be given before referral and acts rapidly on parasites. We investigated whether this intervention reduced mortality and permanent disability. METHODS In Bangladesh, Ghana, and Tanzania, patients with suspected severe malaria who could not be treated orally were allocated randomly to a single artesunate (n=8954) or placebo (n=8872) suppository by taking the next numbered box, then referred to clinics at which injections could be given. Those with antimalarial injections or negative blood smears before randomisation were excluded, leaving 12 068 patients (6072 artesunate, 5996 placebo) for analysis. Primary endpoints were mortality, assessed 7-30 days later, and permanent disability, reassessed periodically. All investigators were masked to group assignment. Analysis was by intention to treat. This study is registered in all three countries, numbers ISRCTN83979018, 46343627, and 76987662. RESULTS Mortality was 154 of 6072 artesunate versus 177 of 5996 placebo (2.5%vs 3.0%, p=0.1). Two versus 13 (0.03%vs 0.22%, p=0.0020) were permanently disabled; total dead or disabled: 156 versus 190 (2.6%vs 3.2%, p=0.0484). There was no reduction in early mortality (56 vs 51 deaths within 6 h; median 2 h). In patients reaching clinic within 6 h (median 3 h), pre-referral artesunate had no significant effect on death after 6 h or permanent disability (71/4450 [1.6%] vs 82/4426 [1.9%], risk ratio 0.86 [95% CI 0.63-1.18], p=0.35). In patients still not in clinic after more than 6 h, however, half were still not there after more than 15 h, and pre-referral rectal artesunate significantly reduced death or permanent disability (29/1566 [1.9%] vs 57/1519 [3.8%], risk ratio 0.49 [95% CI 0.32-0.77], p=0.0013). INTERPRETATION If patients with severe malaria cannot be treated orally and access to injections will take several hours, a single inexpensive artesunate suppository at the time of referral substantially reduces the risk of death or permanent disability.

Abstract
Five alternative techniques for diagnosis of malaria were evaluated in 124 clinically diagnosed cerebral malaria cases admitted in a tertiary hospital in Bangladesh. Clinical diagnosis of cerebral malaria was done by WHO criteria. The tests were conventional routine malaria microscopy; prolonged microscopy; dipstick antigen capture assay (Para Sight TM-F test); pigments in peripheral leucocytes and routine microscopy repeated at 12 hours interval. First four tests were done at 0 hours of hospital admission and repeat routine microscopy was added at 12 hours interval. Diagnostic capability of the test was 64%, 65%, 69%, 27% and 63% respectively. None of the tests except pigments in peripheral leucocytes was superior at initial evaluation. Only the dipstick test added 5% more diagnostic possibility compared with routine microscopy as standard. Stratification of diagnostic capability in different ways improved diagnosis 15% and 11% in smear negative cases by dipstick and prolonged microscopy respectively. It was increased by 50% (5/10 patients) with dipstick test in the smear negative patients with history of anti-malarials prior to hospital admission.

Abstract
Cerebrovascular disease (CVD) is one of the leading causes of morbidity and mortality worldwide and places a huge burden on the health care system. The most common forms of CVD are ischemic cerebrovascular disease (ICVD) and hemorrhagic cerebrovascular disease (HCVD). Since, the treatment, prognosis and rehabilitation of CVD is frustrating, prevention of CVD by properly addressing its modifiable risk factors might be the spearhead to combat the burden. There are several established risk factors associated with CVD, but a newer modifiable risk factor, hyperhomocysteinemia has created a new window for limiting the occurrence of CVD. Homocysteine is potentially vasculotoxic because of its association with endothelial dysfunction and impairment of fibrinolytic system. A total of 248 subjects were included in this case control study. Among them 104 were diagnosed CVD cases (ICVD-59, HCVD- 45) and 144 were age and sex matched healthy controls. Serum total homocysteine was measured in all the study subjects. Mean total homocysteine was found 12.95+/-6.20 micromol/L, 15.55+/-7.35 micromol/L in controls and cases respectively and 15.70+/-7.82 micromol/L, 15.34+/-6.78 micromol/L in ICVD and HCVD respectively. Homocysteine found to be significantly raised in CVD cases compared to controls but sub groups of CVD (ICVD & HCVD) did not differ between themselves with respect to serum homocysteine.

Abstract
BACKGROUND This study sought to describe and quantify microcirculatory changes in the mucosal surfaces of patients with severe malaria, by direct in vivo observation using orthogonal polarization spectral (OPS) imaging. METHODS The microcirculation in the rectal mucosa of adult patients with severe malaria was assessed by use of OPS imaging, at admission and then daily. Comparison groups comprised patients with uncomplicated falciparum malaria, patients with bacterial sepsis, and healthy individuals. RESULTS Erythrocyte velocities were measured directly in 43 adult patients with severe falciparum malaria, of whom 20 died. Microcirculatory blood flow was markedly disturbed, with heterogeneous obstruction that was proportional to severity of disease. Blocked capillaries were found in 29 patients (67%) and were associated with concurrent hyperdynamic blood flow (erythrocyte velocity, >750 mm/s) in adjacent vessels in 27 patients (93%). The proportion of blocked capillaries correlated with the base deficit in plasma and with the concentration of lactate. Abnormalities disappeared when the patients recovered. In healthy individuals and in patients with uncomplicated malaria or sepsis, no stagnant erythrocytes were detected, and, in patients with sepsis, hyperdynamic blood flow was prominent. CONCLUSION Patients with severe falciparum malaria show extensive microvascular obstruction that is proportional to the severity of the disease. This finding underscores the prominent role that microvascular obstruction plays in the pathophysiology of severe malaria and illustrates the fundamental difference between the microvascular pathophysiology of malaria and that of bacterial sepsis.

Abstract
Bangladesh faces growing levels of Plasmodium falciparum resistance to chloroquine (CQ) and sulfadoxine-pyrimethamine (SP). Alternative antimalarial therapies, particularly combination regimens, need to be considered. Therefore, the efficacy of three antimalarial combination therapies was assessed in Chittagong Hill Tracts. A total of 364 P. falciparum patients were recruited and randomly assigned to either CQ + SP, mefloquine + artesunate (MQ + AS) or lumefantrine + artemether (Coartem). Results showed that CQ + SP therapy was less effective than the two artemisinin-based combination therapies. The day 42 PCR-corrected efficacy rate was 62.4% for CQ + SP, 100% for MQ + AS and 97.1% for Coartem. Failures occurred at a shorter interval after CQ + SP treatment than after Coartem. The artemisinin-based therapies effectively prevented development of gametocytes, whereas CQ + SP did not. All three therapies were well tolerated, although reports of mild complaints during treatment appeared higher with MQ + AS. We conclude that CQ + SP is not a viable option for replacing CQ monotherapy as first-line P. falciparum treatment in this area of Bangladesh. A change to artemisinin-based combination therapy is recommended. Both Coartem and MQ + AS appear to be good options, effective in curing P. falciparum malaria and in preventing recrudescences following treatment.

Abstract
The study was an open randomized controlled trial to compare the outcome at 8 weeks with two different modalities in the treatment of 'Frozen shoulder'. Clinical cases with painful limitation of movement of shoulder were randomized to receive physical therapies alone versus physical therapies and shoulder arthrography with intra-articular steroid in a sequential randomization process. Cases suspected of having a concomitant illness and has potential to cause secondary frozen shoulder were excluded, such as, history of trauma to shoulder over the last 6 months, symptomatic clinical cervical degenerative diseases, and causes in and around the shoulder (infective and non-infective). Physical Therapies provided to all patients were therapeutic exercises, transcutaneous electrical nerve stimulation (TENS) and infra-red radiation (IRR). Outcome measures were improvement of pain on a Visual Analogue Scale (VAS) score and range of motion measured by Goniometer at 8 weeks. Patients were followed weekly for 8 weeks and outcome parameters were recorded on every evaluation. The baseline range of motion in the two groups was comparable. At 8 weeks a statistically significant difference in outcome were observed in the two groups. The chi-square means difference of improvement in range of motion for abduction was p <0.00 and for external rotation was p <0. 00. The pain reduction on VAS score was not significant in the two groups (p <0. 40). In the present small series, the distension arthrography with intra-articular (IA) steroid plus physical therapy was superior over physical therapy alone in the functional improvement of the frozen shoulder. Further studies with larger sample size are required to confirm the observations.
