Estimation of Vitamin D levels among Physicians Working in a Tertiary Level Hospital of Bangladesh

Vitamin D is essential for the body to regulate calcium and phosphate levels and mineralization of bone. It is synthesized in the skin after ultraviolet radiation exposure or obtained in the diet to a less extent. Vitamin D deficiency is attracting attention due to higher prevalence in different populations. Physicians of Bangladesh are supposed to be vulnerable to low Vitamin D levels owing to long indoor work hours in both government and private settings. The study was conducted to evaluate Vitamin D status among physicians working in a tertiary level public hospital of Bangladesh. The cross sectional descriptive study was carried out at Mymensingh Medical College Hospital during the period of January 2018 to June 2018. Data were collected from purposively selected 102 doctors of different levels using a case record form. Interview, measurements and laboratory investigations were done accordingly. Vitamin D levels were categorized as deficient (<20.00ng/L), Insufficient (20.00-29.00ng/L), Sufficient (30.00-100.00ng/L) and Potential Toxicity (>100.00ng/L). Among 102 doctors 79(77.5%) were male and 23(22.5%) were female. Maximum (60.8%) were in the age group of 31 years to 50 years. Mean±SD age of the subjects was 49.9±3.61years. Vitamin D deficiency was found in 19(18.6%) subjects and insufficiency was in 49(48.0%) of the subjects. On the other hand 34(33.3%) subjects had sufficient Vitamin D levels. Potential Vitamin D toxicity was not found in any of the subjects. Vitamin D deficiency was found more in female (30.4%) than male (15.2%) but insufficiency was found more in male (50.6%) than female (39.1%). The study revealed that 66.6% physicians had either deficiency or insufficiency of Vitamin D. Exposure to sunlight, dietary intake and Vitamin D supplementation should be considered to increase the status of Vitamin D levels in Physicians of Bangladesh.

Immune response to temperature stress in three bivalve species: Pacific oyster Crassostrea gigas, Mediterranean mussel Mytilus galloprovincialis and mud cockle Katelysia rhytiphora

Summer mortality of some bivalve species is often associated with the change of environmental temperature. This study compares the response of immunological parameters to temperature change in three marine bivalves: Pacific oyster Crassostrea gigas, Mediterranean mussel Mytilus galloprovincialis and mud cockle Katelysia rhytiphora. Each species was exposed to three temperatures, 15 °C, 20 °C and 25 °C for 14 days. The total haemocyte count (THC), phagocytosis, reactive oxygen species (ROS) and the activity of antioxidant enzymes such as superoxide dismutase (SOD) and catalase (CAT) were used as indicators to measure the response of each species to different temperatures. The highest temperature (25 °C) significantly increased the THC and phagocysis of haemocytes in all species. The SOD and CAT activities in the haemocytes of M. galloprovincialis and K. rhytiphora rapidly increased with temperature elevation, concomitantly with the increase of ROS ions. In contrast, the increases of ROS and SOD in C. gigas only occurred from 20 °C to 25 °C, suggesting that this intertidal species is more adaptive to different temperature levels. This study indicates that the activities of antioxidant enzymes can reflect the immune response of marine bivalves to thermal stress. Intertidal species such as Pacific oysters have a greater tolerance to thermal stress than subtidal species (e.g. Mediterranean mussel) and demersal species buried in sand (e.g. cockle).

Haemophagocytic Lymphohistiocytosis in a 16-Year-Old Boy

Haemophagocytosis encompasses phagocytosis of erythrocytes, leukocytes, platelets and their precursors by macrophages in bone marrow and other tissues. Haemophagocytic lymphohistiocytosis (HLH) usually presents with high fever, pancytopenia, splenomegaly, lymphadenopathy, haemophagocytosis in bone marrow, liver, lymphnodes or CSF. We report coagulase negative Staphylococcus induced HLH in a 16 year old boy presenting with high grade fever, lymphadenopathy, hepatosplenomegaly, pancytopenia with neutropenic sepsis in the department of Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh on 28th November 2016. He responded to high dose dexamethasone and management of neutropenic sepsis. This might give a guidance in the management of haemophagocytic syndrome at the earliest time to prevent morbidity and mortality.

Response of Proliferative Lupus Nephritis with Pulse Cyclophosphamide Therapy during Induction Period: A Single Centre Study in Bangladesh

This prospective study was conducted to assess the response of proliferative lupus nephritis with pulse cyclophosphamide therapy during induction period in the department of Nephrology of Dhaka Medical College, Dhaka, Bangladesh from December 2012 to November 2013. A total of 35 clinically diagnosed SLE patients of class III/IV lupus nephritis were included. But 3 patients were dropped out during follow-up, therefore finally 32 patients (class III = 4, class IV = 28) were studied. The patients were evaluated for response on the basis of proteinuria, serum creatinine & active sediment in urine after 6th cycle of cyclophosphamide and 62.5% patients achieved complete response, 25% patients achieved partial response & 12.5% patients achieved no response. The factors favored complete response was early clinical presentation (7 months duration), proteinuria ≤3gm/day& normal renal function during their initial presentation. And higher anti ds DNA titre was an independent predictor for partial response/no response.

Pyrolysis of water hyacinth in a fixed bed reactor: Parametric effects on product distribution, characterization and syngas evolutionary behavior

In this investigation, the effect of operating parameters on product distribution for the conversion of water hyacinth into most valuable product bio oil as well as char and gases are investigated. To observe the parametric effect on product distribution, the temperature was varied 300-600 °C, heating rate 10-50 °C/min, particle size of the feed <0.5-2.5 mm and carrier gas nitrogen flow rate 0-12 lpm. The highest bio-oil yield of 44.9 wt% was obtained at 350 °C, 30 °C/min, particle feed size less than 0.5 mm and 6 lpm. The results show that the product yield is strongly influenced by the temperature variation whereas weakly affected by the heating rate. The biomass and the products were characterized by ultimate, proximate, DTG, FTIR, ¹H NMR, and GC-MS. Syngas evolution increase with the increase of temperature except CO₂. The quality of bio-oil is perspective as a source of value-added chemicals and char is a promising source for the production of carbonaceous materials as well as solid fuel.

Role of Liver Biopsy in the Diagnosis of Neonatal Cholestasis due to Biliary Atresia

Biliary atresia is the commonest cause of cholestatic jaundice. Early diagnosis & surgical correction helps long time survival & prevent development of cirrhosis. This study was conducted to find out the role of liver biopsy in the diagnosis of biliary atresia having positive hepatobiliary scintigraphy as there is chance of false positivity. This cross sectional study was carried out in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh at Paediatric Gastroenterology & Nutrition Department from January 2014 to June 2015. All admitted patients with the diagnosis of neonatal cholestasis were evaluated clinically and by scintigraphy for biliary atresia. Having positive hepatobiliary scintigraphy but highly suggestive of biliary atresia were enrolled for this study. A total of 108 cases were initially selected. Among them 33 patients showed no excretion of tracer during hepatobiliary scintigraphy. Liver biopsy was done in these 33 cases. All cases (100%) had history of passage of pale or acholic stool. Fractionated serum bilirubin of >2mg/dl was found all of the cases. Histological scoring system reveals typical features of biliary atresia in 27(81.8%). Two had no conclusive histology of biliary atresia, four had features of neonatal hepatitis (12.1%). In this study, percutaneous liver biopsy with histological analysis by scoring system was found useful for the correct diagnosis of biliary atresia.

The mitochondrial Nod-like receptor NLRX1 modifies apoptosis through SARM1

NLRX1, the mitochondrial NOD-like receptor (NLR), modulates apoptosis in response to both intrinsic and extrinsic cues. Insights into the mechanism of how NLRX1 influences apoptosis remain to be determined. Here, we demonstrate that NLRX1 associates with SARM1, a protein with a toll/interleukin-1 receptor (TIR)-containing domain also found in adaptor proteins downstream of toll-like receptors, such as MyD88. While a direct role of SARM1 in innate immunity is unclear, the protein plays essential roles in Wallerian degeneration (WD), a type of neuronal catabolism occurring following axonal severing or damage. In non-neuronal cells, we found that endogenous SARM1 was equally distributed in the cytosol and the mitochondrial matrix, where association with NLRX1 occurred. In these cells, the apoptotic role of NLRX1 was fully dependent on SARM1, indicating that SARM1 was downstream of NLRX1 in apoptosis regulation. In primary murine neurons, however, Wallerian degeneration induced by vinblastine or NGF deprivation occurred in SARM1- yet NLRX1-independent manner, suggesting that WD requires the cytosolic pool of SARM1 or that NLRX1 levels in neurons are too low to contribute to WD regulation. Together, these results shed new light into the mechanisms through which NLRX1 controls apoptosis and provides evidence of a new link between NLR and TIR-containing proteins.

Comparison among Different Culture Media for the Detection of Dermatophytes

Dermatophytes are a group of closely related fungi that have the capacity of invading the keratinized tissue of human to produce infections known as dermatophytosis which is commonly referred to as ringworm. Other than routine microscopy, different culture media are available for the detection of dermatophytes from patient's specimen. This cross sectional study was designed to evaluate the outcome of three different culture media and microscopy for the detection of dermatophytes from clinical samples. Skin, hair and nail samples from 84 clinically suspected cases of dermatophytosis who attended at OPD of Dermatology Department, Sylhet MAG Osmani Medical College Hospital, Sylhet, Bangladesh from July 2014 to June 2015 were screened by direct microscopic examination using potassium hydroxide (KOH) mount. All the samples were inoculated for culture in Sabouraud's Dextrose Agar (SDA), Dermatophytes Test medium (DTM) and Sabouraud's Cycloheximide Chloramphenicol Agar (SCCA). The percentage of samples positive by microscopy was 37.5%, whereas the rate of positivity by culture was 47.6% which showed that culture was more sensitive than microscopy for the diagnosis of dermatophytosis. The efficiency of SDA and SCCA was found to be almost equal. There was no statistically significant difference between SDA and DTM in primary isolation of dermatophytes, though isolation rate was slightly higher in DTM. Though direct examination by microscopy is an efficient screening technique, culture should be done for accurate diagnosis. As DTM is easy to evaluate even without handling the growth of culture in the laboratory, it is recommended to use as screening medium for the detection of dermatophytes.

Prevalence of Microalbuminuria and Overt Proteinuria in Diabetes Mellitus and their Association with Renal Function

This cross sectional observational study was conducted in the Department of Nephrology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from April 2009 to March 2010. Samples were collectedfrom rural area of Khalishaur union of Purbadhala upazilla in Netrakona District, 30km away from Mymensingh Town. The main objective of the study was to find out the prevalence of microalbuminuria as well as overt proteinuria in diabetes mellitus in a rural population and to observe their association with renal function. In this study 1048 adult participants of 18 to 65 years in a rural area of Netrakona were included purposively as study subjects. Among them 54% were male and 46% were female. Mean age of study subjects was 42.4±13.4 years. Prevalence of microalbuminuria among diabetic participants was 29.72% where as in non diabetic non hypertensive participants it was 6.62%. Diabetic persons 9.45% and 3.9% of non diabetic participants showed overt proteinuria by dipstick test. Prevalence of hypertension in diabetic and non diabetic participants was 45.94% and 16.52% respectively. The mean eCCr of the diabetic patients and non-microalbuminuric healthy persons was 78.4±25.4 ml/min/1.73m² and 94.67±24.8 ml/min/l.73m² respectively according to Cock Croft-Gault equation. The mean eCCr of diabetic participants with overt proteinuria was 57.44±28.33 ml/min/l.73m² but diabetic patients with microalbuminuria had better mean eCCr 80.62±21.17 ml/min/1.73m² which justifies the importance of detection of microalbuminuria for early intervention. By regression analysis it was found that degree of microalbuminuria had linear relation with renal function and random blood sugar level. Neither BMI nor duration of diabetes showed any correlation with urine microalbumin. There was no effect of sex on the prevalence of microalbuminuria in diabetes mellitus. Microalbuminuria is the first sign of renal involvement in diabetic patients which is a risk factor for overt nephropathy. Monitoring of this condition is important because early treatment of microalbuminuria can prevent or postpone overt nephropathy.

Comparison of Outcome of Eclamptic Patient Following Vaginal Delivery versus Caeserian Delivery by Spinal Anaesthesia

Eclampsia is a common problem in pregnancy in Bangladesh. It is a severe form of preeclampsia which affects 5 to 7% of pregnancies is a significant cause of maternal & neonatal morbidity & mortality. Pre-eclampsia when complicated with generalized tonic-clonic convulsions and/or coma is called eclampsia. The term eclampsia is derived from a Greek word, meaning "like a flash of lightening". It may occur quite abruptly, without any warning manifestations. Eclampsia is a major cause of maternal mortality & morbidity as well as foetal loss worldwide, particularly in the third world. Appropriate measures & effective treatment of eclamptic patient in proper time reduce maternal mortality & morbidity. The mainstay of treatment of eclampsia is delivery of the foetus. Two methods are usually applied for delivery of foetus in eclampsia i.e. vaginal delivery & caesarean delivery. This study was done in the department of Gynae & Obs and department of Anaesthesiology, Mymensingh Medical College Hospital from 1st January 2016 to 30th June 2016 to observe the incidence, complications (morbidity) & mortality of eclamptic patients & which method (vaginal delivery versus caesarean delivery by spinal anaesthesia) is safe, better for the eclamptic patients as well as foetal mortality. Successful vaginal delivery is dependant on complex interactions of three variables (3 P) that is power (uterine contraction), passenger (foetus) & passage (birth canal) but power is less effective in eclamptic patient than normal partuents. Vaginal delivery requires prolong times compared with cesarean delivery. Anaesthetic technique is also an important factor for maternal mortality & morbidity of caesarean delivery. Spinal anaesthesia is widely regarded as a reasonable anaesthetic option for caesarean delivery in eclamptic patients. Currently the safety of spinal anaesthesia is well established and it can provide better obstetrical outcome when chosen properly. In this observation caesarean delivery by spinal anesthesia is safer, less complications, less maternal & neonatal mortality than vaginal delivery in eclamptic patients.

Association between Serum Apolipoprotein-B and Acute Ischaemic Stroke

Stroke is one of the leading causes of death and disability in developed as well as developing countries like Bangladesh. There is a crucial need to identify additional risk factors that are easily measurable and treatable in general population. Role of serum lipids, lipoproteins and lipoprotein related variables in the prediction of stroke is less clear. Abnormalities in plasma lipoproteins are the most firmly established and best understood risk factors for atherosclerosis and they are probable risk factors for ischaemic stroke, largely by their link to atherosclerosis. High serum apolipoprotein-B (Apo-B) levels may predict an increased risk for ischaemic stroke. Aim of the study was to evaluate the association between serum Apo-B level and acute ischaemic stroke and to measure and compare serum Apo-B level in ischaemic stroke and normal subjects. A cross-sectional comparative study was carried out in the department of Neurology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2013 to June 2015. A total number of 100 subjects within 18-70 years were considered for the study. Fifty (50) subjects with stroke (both clinically as well as CT scan of head or MRI of brain proven) were taken as the cases and 50 age and sex matched nearly healthy individuals without stroke were taken as the controls by using non-probability sampling procedure. Total cholesterol, HDL cholesterol and triglycerides were estimated by enzymatic method using Semiautoanalyser. LDL cholesterol was estimated by Friedewald formula. Apo-B was estimated by immunoturbidimetric method using Semiautoanalyser. Finally collected data were analyzed by using SPSS software Version 20. Student 't' test was used to compare the data between cases and controls. P value was set <0.05. Diagnostic validity tests were conducted to assess the diagnostic efficiency of Apo-B. Total cholesterol, LDL cholesterol and triglycerides are significantly increased in cases compared to controls. HDL-cholesterol was significantly decreased in cases compared to controls. Apo-B was significantly increased in cases compared to controls. The result was statistically significant. Apo-B may be used as predictors of ischaemic stroke components.

Mechanisms underlying the lack of endogenous processing and CLIP-mediated binding of the invariant chain by HLA-DP84Gly

While the principles of classical antigen presentation via MHC class II are well-established, the mechanisms for the many routes of cross-presentation by which endogenous antigens become associated with class II molecules are not fully understood. We have recently demonstrated that the single amino acid polymorphism HLA-DPβ^84Gly (DP^84Gly) is critical to abrogate class II invariant chain associated peptide (CLIP) region-mediated binding of invariant chain (Ii) to DP, allowing endoplasmic reticulum (ER)-resident endogenous antigens to constitutively associate with DP^84Gly such as DP4. In this study, we demonstrate that both the CLIP and N-terminal non-CLIP Ii regions cooperatively generate an Ii conformation that cannot associate with DP^84Gly via the CLIP region. We also demonstrate the ability of DP4 to efficiently process and present antigens encoded in place of CLIP in a chimeric Ii, regardless of wild type Ii and HLA-DM expression. These data highlight the complex interplay between DP polymorphisms and the multiple Ii regions that cooperatively regulate this association, ultimately controlling the presentation of endogenous antigens on DP molecules. These results may also offer a mechanistic explanation for recent studies identifying the differential effects between DP^84Gly and DP^84Asp as clinically relevant in human disease.

The Pattern of Serum Calcium, Phosphate and Parathyroid Hormone Levels in Pre-Diagnosed Chronic Kidney Disease Patients

Chronic kidney disease (CKD) is an international health problem affecting 5-10% of the world population. Patients with chronic kidney disease were known to have higher prevalence of changes in serum calcium, phosphate and parathyroid hormone in Western countries, but data on the impact of CKD on serum calcium, phosphate and parathyroid hormone in our country are scarce. This cross-sectional type of descriptive study was conducted in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from March 2016 to September 2016. The aim of this study is to estimate serum calcium, phosphate and parathyroid hormone levels in chronic kidney disease (CKD) patients for early recognition of abnormalities, understanding of their patho-physiological consequences & planning management strategies to prevent their progression, thus reducing the morbidity & mortality. This study shows Hypocalcemia, hyperphosphataemia and elevated serum PTH levels are noted in later CKD stages & worsen with disease progression.

Dog Sperm Cryopreservation in Glucose-Fructose or Sucrose Supplemented Glycerol-Free Tris: Effect of Post-Thaw Incubation Time on Gene Expression Related to Apoptosis and Motility

　　OBJECTIVE: The study evaluated the effects of glucose-fructose or sucrose supplementation in glycerol-free Tris (GFT) solution on motility, viability, the level of reactive oxygen species (ROS), as well as the level of apoptosis (BAX and BCL2) and motility (SMCP)-related gene expression of dog spermatozoa.

MATERIALS AND METHODS

Spermatozoa (5×10⁷ sperm/ml) were cryopreserved in GFT containing 86 mM glucose and 86 mM fructose (GF-GFT) or 100 mM sucrose (S-GFT). Progressive motility, viability, ROS (H₂O₂) level and mRNA gene expression of spermatozoa were evaluated 0 h, 3 h or 6 h post-thaw at 24°C.

RESULTS

The motility of spermatozoa cryopreserved in GF-GFT was increased throughout the post-thaw incubation time. The motility of spermatozoa cryopreserved in S-GFT was increased at 3 h of post-thaw incubation. The sperm ROS level in the GF-GFT group was inconsistent during the post-thaw incubation time; however, the ROS level in the S-GFT group was gradually increased with progression of the post-thaw incubation period. The post-thaw incubation had no substantial effect on the mRNA expression of the BAX, BCL2, and SMCP genes of spermatozoa in both the GF-GFT and S-GFT groups.

CONCLUSION

The supplementation of glucose and fructose improves progressive sperm motility during 6 h of post-thaw incubation while maintaining similar sperm viability. The addition of GF to GFT for cryopreservation and post-thaw incubation would yield more functional spermatozoa for future assisted reproduction practices.

Correlation of Ball Circumference with Body Weight in 5-10 Years Aged Bangladeshi Children

This cross sectional, descriptive and analytic study was conducted among 5-10 years aged 109 Bangladeshi children (70 male and 39 female) at different areas of Mymensingh district (Fulpur, Muktagacha, Fulbaria, Trisal and Haluaghat), Bangladesh from January 2016 to December 2016. Sample collection was done by nonrandom purposive sampling technique. Any kind of congenital and acquired foot deformity was excluded to construct standard measurement. The present anthropometric study was designed to construct data of 5 to 10 years aged Bangladeshi children regarding ball circumference, to measure its correlation with body weight and this attempt has been made out to grow interest among the researchers for future study and also to compare the data with the data of the people of other races. Weight of the subject was measured with the digital weighing machine and ball circumference was measured using flexible measuring tape. The children were asked to stand with weight distributed equally on both feet. The legs were perpendicular to the feet. The mean ball circumference of right side of 5, 6, 7, 8, 9 and 10 years aged male were 16.93±1.05cm, 17.00±0.72cm, 18.10±1.28cm, 18.33±.99cm, 19.37±1.12cm and 19.94±1.30cm respectively and those of female were 16.27±1.10cm, 16.85±0.59cm, 17.44±0.92cm, 18.02±0.82cm, 18.00±1.58cm and 19.23±1.40cm respectively. The mean ball circumference of left side of 5, 6, 7, 8, 9 and 10 years aged male were 16.86±1.05cm, 16.94±.70cm, 18.02±1.29cm, 18.26±.99cm, 19.27±1.12cm and 19.87±1.29cm respectively and those of female were 16.18±1.10cm, 16.77±0.62cm, 17.36±0.92cm, 17.98±0.87cm, 17.90±1.58cm and 19.13±1.40cm respectively. In this study on both sides, ball circumference showed non-significant positive correlation with body weight in 5 years old male and female, 6 years old male and female, 7 years old male and female, 8 years old female, 9 years old male and female and 10 years old male and female. In case of 8 years old male, it showed non-significant negative correlation with body weight.

Evaluation of Intraoral Burning Sensation in Response to Heat-Cured and Self-Cured Acrylic Resin Denture Base Material

The objective of this prospective experimental clinical trial was to evaluate intraoral burning sensation in response to heat-cured and self-cured acrylic resin denture base material and carried out in the department of Prosthodontics of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from February 2014 to September 2015. Forty eight patients were evaluated in this study; of them 35(72.92%) patients were male and 13(27.08%) patients were female with age range from 24 to 70 years. In this study 48 patients were evaluated in term of burning sensation, of them 24 patients were provided with heat-cured acrylic resin denture and were considered as Group A and 24 patients were provided with self-cured acrylic resin denture and were considered as Group B. In Group A 14(58.4%) at 1st week, 2(8.4%) at 1st month, 10(41.8%) at 3rd month and 5(21.0%) at 6th month developed burning sensation. On the other hand the values were 18(75.0%), 22(91.6%), 14(58.2%) and 2(8.4%) at 1stweek, 1st month, 3rd month, and 6th month respectively. Chi-square test was done for statistical analysis and p value was <0.05. So, results were statistically significant.

Magnetic Resonance Imaging in Evaluation of Sinonasal Masses with Histopathological Correlation

Sinonasal mass is the abnormal growth of tissue from nasal cavity and mucosa of the paranasal sinuses. The growth may be benign or malignant. The benign lesion grows slowly and does not metastasize. The malignant lesion grows rapidly and metastasizes early. The aim of this study is to evaluate and diagnose the various types of sinonasal masses with MRI and its correlation with histopathological findings. This cross sectional descriptive study was carried out for a period of 02 years, from July 2015 to June 2017. The patients were selected from the ENT outpatient department and from the department Radiology & Imaging of Mymensingh Medical College Hospital, Mymensingh, Bangladesh who were reported as case of sinonasal masses. Thirty three (33) patients (17 males and 16 females) with sinonasal masses were included after fulfilling exclusion & inclusion criteria which was confirmed by proper clinical examination & were subjected to MRI and histopathological examination. The age range was 11 to 85 years. The nasal cavity was the most commonly involved site with sinonasal malignancies (were 4 cases, 12.12%) followed by the maxillary sinuses (were 2 cases, 6.06%). The least commonly affected site was the frontal sinuses (was 1 case, 3.03%). Histopathological findings shows benign sinonasal tumors were present in 25 cases. The most common benign lesion was sinonasal polyposis 10 cases (30.30%), followed by inverted papilloma 6 cases (18.18%) & juvenile nasopharyngeal angiofibroma 6 cases (18.18%), adenoma 02 cases (6.06%), and one case was rhinosporidiosis (3.03%). Malignant sinonasal tumors were present in 8 cases. Most common malignant tumors were nasopharyngeal carcinoma in 4 cases (12.12%), adenoid cystic carcinoma in 3 cases (9.09%) and non-Hodgkin lymphoma was present in 01 case (3.03%). MRI report shows benign masses in 23 cases of which nasopharyngeal polyposis was 10(30.30%), inverted papilloma 6(18.18%), juvenile angiofibroma 4(12.12%), adenoma 02(6.06%) & rhinosporidiosis 1(3.03%). Among 10 malignant tumors nasopharyngeal carcinoma were 6(18.18%), adenoid cystic carcinoma 3(9.09%) & non-Hodgkin lymphoma 1(3.03%). MRI findings of malignant sinonasal masses revealed that sensitivity 87.5%, specificity 40.0%, positive predictive value (PPV) 70% & negative predictive value 66%. Statistically significant association was observed between histopathology & MRI findings, p value was 0.305. Statistically significant association was found between histopathology & MRI findings.

Prevalence of GERD in Type II Diabetes Mellitus Patients Admitted in A Tertiary Care Hospital of Bangladesh

Gastroesophageal reflux disease (GERD) is defined as symptoms or complications associated with regurgitation from the stomach and/or the duodenum to the esophagus. Patients with type II diabetes mellitus (DM) were known to have higher prevalence of GERD in the Western countries, but data on the impact of GERD on DM patients in our country are scarce. The aim of this cross-sectional study was to evaluate the presence of GERD in type II DM patients admitted at the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from April 2015 to September 2015. A total of 137 type II DM cases were purposively collected. Reflux Disease Questionnaire (RDQ) was used to check the presence of GERD. Patient's characteristics, laboratory data, face-to-face interview data were analyzed. Out of 137 type 2 DM patients 108 were suffering from GERD giving a prevalence rate of 78.8% which is quite high. Pathophysiological factors like age, sex, duration of DM, weight, waist circumference (WC) had no significant difference between GERD-DM and non-GERD-type II DM patients. Only hypertension and frequent eating fatty food were found to have significant differences between the two groups. From the study findings it could be said that the higher rate of GERD in patients with type II DM may be associated with lifestyle factor and some pathophysiological factors like hypertension. Psychiatric factors may also play role in contributing GERD. Further in-depth and large scale studies are necessary in our country in this regard.

Acute Kidney Injury in Patients with Acute Viral Hepatitis: A Study in a Tertiary Care Hospital

This cross sectional observational study was done in the Department of Medicine, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from May 2013 to April 2014 to find out the proportion of acute kidney injury among patients with acute viral hepatitis and to identify risk factors associated with development of acute kidney injury (AKI). A total of 100 patients with acute viral hepatitis were included purposively as study subjects. Among them 61 were male and 39 were female. They were divided into AKI group (n=6) and non-AKI group (n=94) on the basis of development of AKI. There was no significant difference in mean age (39.0±13.1 years vs. 32.2±10.8 years, p=0.335) and sex (67% vs. 61% & 33.0% vs. 39.0%) p=0.769) between AKI group and non-AKI group. There were 27% acute viral hepatitis A, 21% acute viral hepatitis B and 52% acute viral hepatitis E but no case of acute viral hepatitis C was found in this study. Acute kidney injury (AKI) developed in 6 of 27 patients with acute viral hepatitis A. This study showed that 22.2% patients with acute viral hepatitis A developed acute kidney injury but patients with acute viral hepatitis B (HBV) and hepatitis E (HEV) did not develop acute kidney injury. Majority of the patients with acute kidney injury were smokers and hypertensive with elevated mean arterial pressure (p=0.0001) at presentation and had higher total bilirubin (p=0.0001), alanine aminotranseferase values (p=0.040), prolonged prothrombin time (INR) {p=0.0001}, lower albumin (p=0.0001), lower haematocrit level (p=0.0001), high CRP concentration (p=0.0001), leucocytosis (p=0.0001) and thrombocytopenia (p=0.0001) at presentation than patients without acute kidney injury. It is evident from the study that acute kidney injury is not a rare complication in patients with acute viral hepatitis.

Outcome of Pregnancy Related Acute Kidney Injury Observed in a Tertiary Care Hospital

This prospective case control study was carried out in Mymensingh Medical College Hospital (MMCH) from April 2011 to March 2012. The main objective of the study was to determine the short term maternal outcome of pregnancy related Acute Kidney Injury and to identify aetiological factors and to observe clinical features of pregnancy related Acute Kidney Injury. Total 60 pregnant women with AKI were included in the study as sample and equal (60) number of pregnant women with normal renal function was taken as control. Mean ages (±SD) of study and control group were observed 31.6±6.9 years and 25.5±4.7 years respectively. It was observed that most patients were from rural area with low income group. Most women were multiparous and presented in third trimester and postpartum period. Majority of the study subjects did not receive antenatal care at any stage of pregnancy. Fifty (86.7%) of the study subjects were oligo-anuric, forty-nine (81.7%) were edematous and fifty one (85%) were anaemic. Twenty-five (41.7%) patients presented with abnormal vaginal bleeding. Sepsis (including septic abortion and puerperal sepsis) was responsible for of Pregnancy Related AKI (PR-AKI) in more than two fifths of cases. Haemorrhage (APH & PPH combined) was the next common cause of Pregnancy Related AKI (PR-AKI). Toxemia of Pregnancy was responsible in one fourth of cases. Dialysis (HD & IPD combined) was required for two fifths of the patients. Rest patients were treated conservatively with antibiotics, blood transfusion, maintenance of fluid and electrolytes balance etc. Maternal outcome of Pregnancy related acute kidney injury was considered for the period of patient's hospital staying. 56.6% patients recovered completely, 15.0% patients recovered partially, 6.7% did not recover at the time of hospital discharge; while 21.7% died. So it can be concluded that, pregnancy related acute kidney injury is a critical condition, associated with worse prognosis.

Psychiatric Disorders in Drop out from Educational Attainment Attending Mental Health Facilities: A Descriptive Cross Sectional Study

Studies of the impact of mental disorders on educational attainment are rare. Mental disorders, those beginning in childhood or adolescence may increase the risk of early drop out from education. The latter has been shown to have adverse life-course consequences on individuals such as greater demand on social welfare entitlements. A descriptive cross sectional study was carried out at the department of Psychiatry, Comilla Medical College, Comilla, Bangladesh. All cases were selected from patients attending at Comilla Medical College Hospital and Private Mental Health Facilities in Comilla City from March 2015 to February 2016. We found out the psychiatric disorders and socio-demographic status of patients with educational drop out over the early life course. A total of 50 dropout patients aged 10 to 30 years who fullfiled the enrolment criteria included in the study. Sociodemographic questionnaires, diagnostic information (DSM-5 and ICD-10) as well as an account of a various level of education were used as research instruments. The Frequency tables, summary tables and appropriate graphs were prepared to describe the population characteristics and study finding. The most of the psychiatric morbidity presents in male (62%) and age group of 18-24 years (54%). In this study, anxiety disorders was 8%, behaviour/ impulse control disorders was 8%, mood disorders was 16%, substance use disorders was 24%, schizophrenia spectrum disorders was 12% and composite psychiatric disorders was 32%. Among drop out patient's non- completion of primary education was 14%, non-completion of secondary education was 20%, non- completion of higher secondary education was 24%, not entry to tertiary education was 12% and non-completion of tertiary education was 30%. Among behaviour/impulse control disorders non-completion of primary education was 6%, substance use disorders non-completion of higher secondary education was 10%, mood disorder both non-completion of higher secondary education and non-completion of tertiary education were 6%. Among composite psychiatric disorders non-completion of secondary education, non-completion of higher secondary education and non-completion of tertiary education were 8%, 6% and 12% respectively. Onset of mental disorders and subsequent drop out from education was found in this study. Further multi-centered prospective and population-based studies should be designed to find out the exact situation.

Quality of Life in Children with Asthma in Bangladesh

Asthma is a public health problem that adversely affects different aspects of quality of life. Childhood asthma is common in Bangladesh affecting their lifestyle. The objective of the study was to assess health-related quality of life in children with bronchial asthma. A descriptive, cross-sectional study was carried out from January 2014 to December 2014 at the Outpatient Department of National Asthma Centre, Mohakhali, Dhaka among hundred sixty-two purposively selected children of both sexes with bronchial asthma aged from 7 to 17 years. Data were collected through interview with children or their parents using an interviewer-administered questionnaire based on Pediatric Asthma Quality of Life Questionnaire (PAQLQ). Data were analyzed by computer software SPSS version 16.0. The mean age was 12.5 years with a standard deviation (SD) of 2.9 years. Overwhelming majority 157(96.9%) of children were literate, while only 5(3.1%) children were illiterate. Eighty (49.4%) children were male, while 82(50.6%) female. As many as 148(91.4%) children were students, while 10(6.2%) children were engaged in some type of job and 4(2.5%) children had no occupation. Parents of 145(89.5%) children were currently married, while 10(6.2%) children had single parent and 7(4.3%) children's parents were divorced or separated. Quality of life in children with asthma decreases with age as the disease intensity increases with age. Female asthmatic children had lower overall score of Quality of life (p=0.017), as well as lower activity domain score (p<0.001). Emotional domain score was found lower in children with single parent (p=0.021) and low monthly family income (p<0.001). Furthermore, children with lower monthly family income and working children had lower Quality of life score in all domains.

Outcome of Upper Gastrointestinal Surgery With or Without Nasogastric Intubation

Nasogastric intubation is a common procedure with both merits and demerits. Controversies exist about the routine use of nasogastric intubation following upper gastrointestinal surgery. Good numbers of literatures were published in favour of selective nasogastric intubation pointing out some complications of routine use of nasogastric tube. In 1995, Cheatham et al. concluded in a meta-analysis that although patients may develop abdominal distension or vomiting without a nasogastric tube, this is not associated with an increase in complications or length of hospital stay. For every patient requiring insertion of a nasogastric tube in the postoperative period, at least 20 patients will not require nasogastric decompression. In July 2004, Cochrane database of systemic review published the result of their systemic review on the prophylactic decompression after abdominal surgery, that review was revised and updated in 2007. According to this database, routine nasogastric intubation should be abandoned in favour of selective use of nasogastric tube. In our country some surgeons are practicing it routinely and some are not. This observation prompted us to conduct this study in order to see and compare the outcome of upper gastrointestinal surgery with and without nasogastric intubation. This will help us to make decision whether nasogastric intubation will be done routinely or not following upper gastrointestinal surgery.

Multimodality Treatment Outcome of Hepatoblastoma in a Resource Limited Country

Our objective is to review the records of management of hepatoblastoma (HB) at the Paediatric Haematology and Oncology (PHO) department in the Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2004 to December 2012. This is a retrospective study of clinical, radiological and pathological data of hepatoblastoma patients treated at our institution. Thirteen patients were treated for HB between 2004 and 2012. The records of clinical presentations, chemotherapy tolerance and response, surgical procedure undertaken, and complications were analyzed. Median age of the study population was 12 months (3-60 months) and male: female was 3.3:1. Nine patients were treated with neoadjuvant chemotherapy consists of cisplatin and adriamycin. Primary surgery was done in four patients. Extent of hepatic resection in the operated patients varied. Mixed type was the predominant histopathological diagnosis. Adjuvant chemotherapy was well tolerated with no morbidity or mortality. Five-year event-free survival (EFS) and overall survival (OS) of all the 13 patients is 76.9%. All the nine patients who could complete multimodality treatment are alive with no evidence of disease or complications with median follow-up of 63 months (46-122 months). Treatment of HB with multidisciplinary approach was well tolerated. OS and EFS of patients were comparable with published studies.
