ABSTRACT
Infections due to hepatitis A (HAV), hepatitis B (HBV), hepatitis C (HCV) and hepatitis E (HEV) viruses are the major causes of hepatitis and are associated with significant morbidity and mortality in developing countries like Bangladesh. The aim of this study was to assess the distribution pattern of serological markers in patients of acute viral hepatitis. This was a hospital based observational cross sectional study among purposively selected 107 patients admitted with acute viral hepatitis in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from April 2017 to September 2017. Data were collected by face-to-face interview of the patients, clinical assessment and investigations of biochemical and serological parameters using a structured questionnaire. Descriptive analysis was done using the analytic software SPSS version 21.0. The mean age of the patients was 33.35±12.97 years. Majority was male (68.2%), Muslim (87.9%), married (72.9%) and came from urban area (63.6%) with different level of educational qualifications. The prevalence of viral hepatitis is higher in male (68.22%) than female (31.78%). The common clinical presentations were dark coloured urine (100.0%), yellow colouration of the sclera (100.0%), anorexia (90.6%), nausea/vomiting (79.4%) and abdominal pain (68.2%). Of the 107 patients, 51.40% (n=55) had acute viral E hepatitis, 36.40% (n=39) had acute viral B hepatitis, 12.15% (n=13) had acute viral A hepatitis. Mixed infection with both hepatitis E and A viruses was 1.87% (n=2). HEV and HBV are common in relatively older age while HAV is common in relatively younger age to cause acute viral hepatitis. The study revealed a high prevalence of HEV followed by HBV and HAV in the Bangladeshi population suspected of having suffered from acute viral hepatitis.

BACKGROUND: Little is known about whether and to what extent gender differences affect the stimulation children receive at home, which is crucial to child development. The aim of this study was to document the differences, if any, in the quality of psychosocial stimulation boys and girls receive at home in middle childhood in rural Bangladesh. METHODS: This study was done as a part of a long-term follow-up study of a cluster randomized controlled trial in 2015. The Middle Childhood-Home Observation for Measurement of the Environment (MC-HOME) was adapted and used to measure the quality of home stimulation. Post hoc analysis of the long-term follow-up study was done. Data were analysed using t-test and chi-squared test for continuous and dichotomous variables, respectively. Multiple regression analysis was conducted to control for confounders. RESULTS: A total of 372 child-mother dyads participated in the study. Socio-economic and anthropometric characteristics of the boys and girls did not differ except that more girls had electricity at home (p = .027). Girls were found significantly advantaged over boys in total MC-HOME scores (p = .014) at age around 8 years. CONCLUSIONS: These findings will play a role for child development policy formulation in Bangladesh. However, though the difference is statistically significant, the strength of relationship is very weak and may not be of functional importance.

Family structure is an important factor for children's overall development. In this cross sectional study, we explored how single parenting relates to child's language development in slums of Dhaka city, Bangladesh from 31st August 2010 to 9th February 2011. Children aged 10 to 24 months (n=133), living with mother only and those living with both parents were included. Children's comprehensive and expressive language development was assessed using the Bengali version of Mac Arthur's Communicative Development Inventory (MCDI). Family care indicators (FCI) were used to assess quality of psychosocial stimulation at home, maternal depression was assessed using Centre for Epidemiological Studies - Depression (CES-D) questionnaire and socioeconomic status (SES) of the family was determined using a previously tested questionnaire. We analyzed the data using multivariate analysis. Maternal depression scores were higher in single mothers compared to those living with their husband and more depressed mothers provided less stimulating environment for the child. Children in the single parent families had lower scores on FCI and their comprehension and expression scores were slightly lower. Multiple regressions analysis showed that children's comprehension {B (95%CI), 0.19 (0.07, 0.32), p=0.003} and expression {0.18 (0.02, 0.35), p=0.032} scores were significantly higher in those living with both parents. Steps to educate parents on the importance of a healthy family life needs to be taken in order to ensure development of children to achieve their full potentials. Further long-term effects of living without father on children's development needs to be explored in Bangladesh.

In an atmospheric pressure surface barrier discharge the inherent physical separation between the plasma generation region and downstream point of application reduces the flux of reactive chemical species reaching the sample, potentially limiting application efficacy. This contribution explores the impact of manipulating the phase angle of the applied voltage to exert a level of control over the electrohydrodynamic forces generated by the plasma. As these forces produce a convective flow which is the primary mechanism of species transport, the technique facilitates the targeted delivery of reactive species to a downstream point without compromising the underpinning species generation mechanisms. Particle Imaging Velocimetry measurements are used to demonstrate that a phase shift between sinusoidal voltages applied to adjacent electrodes in a surface barrier discharge results in a significant deviation in the direction of the plasma induced gas flow. Using a two-dimensional numerical air plasma model, it is shown that the phase shift impacts the spatial distribution of the deposited charge on the dielectric surface between the adjacent electrodes. The modified surface charge distribution reduces the propagation length of the discharge ignited on the lagging electrode, causing an imbalance in the generated forces and consequently a variation in the direction of the resulting gas flow.
ABSTRACT
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.

Esophageal varices are a serious consequence of portal hypertension in patients with chronic liver diseases. Several studies have evaluated possible noninvasive markers of esophageal varices to reduce the number of unnecessary endoscopies in patients with chronic liver disease. Aim of this study was to identify clinical and laboratory predictors of esophageal varices in children with chronic liver disease. This cross sectional observational study was done at Pediatric Gastroenterology and Nutrition Department of Bangabandhu Sheikh Mujib Medical University, Dhaka, over a period of 6 months. Fifty (50) consecutive cases of chronic liver disease patient under 15 years of age were evaluated clinically, biochemically and endoscopically. Esophageal varices were classified into 4 grades according to Conn's grading system. Based on endoscopic findings (presence/absence of esophageal varices) all the patients were categorized into two groups; Group I: Chronic liver disease with esophageal varices and Group II: Chronic liver disease without esophageal varices. Most (51.5%) of the patients in Group I belong to age 10-12 years and majority 35.3% of Group II patients belong to ≤2 years. More than half of the (51.5%) patients had grade III varices followed by 24.2% grade II, 21.2% grade I and only 3.0% had grade IV. All patients had splenomegaly in Group I and 70.6% of Group II, which was significantly (p<0.05) higher in Group I. Jaundice, spider angioma, hepatomegaly and ascites werealmost alike between two groups. Platelet count <1,50,000/mm³ in 72.73% patients of Group I and 41.18% in Group II, which was significantly (p<0.05) higher in Group I. Similarly, Serum albumin <3.5mg/dl in 78.79% patients of Group I and 47.6% of Group II, was also significantly (p<0.05) higher in Group I. Serum bilirubin, serum alanine aminotransferase and International normalized ratio (INR) were almost similar between two groups. Wilson's disease was found in 42.4% of chronic liver disease with esophageal varices and 35.3% of Chronic liver disease without esophageal varices. Hepatitis B virus infections were 6.1% and 5.9% in Group I and Group II respectively. Unknown cause was found 42.4% and 17.6% in Group I and Group II respectively. Splenomegaly, Platelet count <1,50,000/mm³ and serum albumin <3.5mg/dl are important predictors of esophageal varices. These three parameters can be used independently to predict esophageal varices in children with chronic liver disease.

The objective of this study was to identify different barriers to healthcare access for international students in China. The study employed a cross sectional descriptive study using both qualitative and quantitative method. A representative sample of international students of a reputed university in China completed a mail back survey having a response rate of 7.5%. Identified barriers are classified as Cognitive, Financial and Structural barriers. One third (36.9%) international students perceived their health condition in China as bad in comparison with their home countries. More than two third of the students did not know their health insurance coverage. Around 71% students agreed that language was a barrier to health care access in China and majority of them think that interpreter service should be available at hospitals. To improve healthcare access - formal interpreter services, translated materials, reconsideration of health insurance should be taken into account. As per our knowledge, this is the first study to investigate healthcare access barriers for international students in China. Further large scale study should be undertaken.

Obesity is increasing in developed as well as in developing countries. This analytical cross sectional study was carried out to document the relation between blood pressure, serum creatinine and body mass index in female and to assess potential health differences among obese female and normal weight female. This study was done in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2012 to June 2013. Seventy female persons volunteered as subjects. Among them 35 were within normal weight (BMI 18.5-24.9kg/m²) and 35 were obese (BMI≥30kg/m²). Non probability purposive type of sampling technique was used to select the subjects. Measurement of body mass index and blood pressure were done as per procedure. Serum creatinine level was estimated by enzymatic colorimetric method. The results were calculated and analyzed by using SPSS (statistical package for social science, version 17.0), scientific electronic calculator and simultaneously with a computer assisted program like Microsoft excel. Unpaired 't' test was applied to find the significance of difference regarding serum creatinine and blood pressure levels in obese female. The value of p was 1% to indicate highly significant and 5% to indicate simply significant or statistically significant. The mean±SE of systolic blood pressure, diastolic blood pressure and serum creatinine levels were 135.71±1.58mmHg, 88.74±0.95mmHg and 1.03±0.01mg/dl respectively; significant at 1% level for obese group of BMI (p<0.0001). The examinations and biochemical investigations revealed that high BMI is significantly related to increased levels of serum creatinine & blood pressure in obese female which indicate the obese subjects are prone to cardiovascular & metabolic risk.

This cross-sectional observational study was conducted in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh over a period of 6 months from October 2011 to April 2012 and was carried out to evaluate the relation of different grades of esophageal varices with Child-Pugh classes of cirrhosis of liver patients. A total 37 patients were included. Child-Pugh score and esophageal varices of each patient were noted. Relation was carried out using the Chi-square test through determining the association of different variables. P value <0.05 was considered significant. Among 37 patients, 27(73%) were male and 10(27%) were female and their frequency of age were found, 7(18.9%) from 18-38 years, 18(48.7%) from 39-59 years and 12(32.4%) from 60 years of age and above. The etiology of liver cirrhosis revealed 18(48.7%) hepatitis B virus, 3(8.1%) hepatitis C virus and 16(43.2%) others causes. Child-Pugh classes were observed 3(8.2%) Class A, 17(45.9%) Class B and 17(45.9%) Class C and grades of esophageal varies were 13(35.1%) F1, 20(54.1%) F2 and 4(10.8%) F3 patients among total. A statistically significant positive relation was found that higher grade of esophageal varices was seen in the more advanced class of Child-Pugh classes with a p value 0.001.

This cross sectional descriptive study was done to find out common clinical presentations, etiologies and laboratory investigation abnormalities in patients of periodic paralysis. Study was carried out in 30 patients with an age range from 8 to 70 years who were enrolled from July 2008 to June 2009 in Mymensingh Medical College Hospital (MMCH) medicine unit. Individuals who were admitted with sudden onset generalized muscle weakness, had history of previous attack and serum potassium level <3mmol/l or >5.5mmol/l were included in this study. In this series, majority of the patients were male (66.67%). Male: female ratio was approximately 2:1. The mean age of the patients was 27.4±4.5 years. Majority (26.67%) of them were in age range of 31-40 years. About 30% of the patients experienced the first attack of paralysis at the age of 20-24 years. Majority of patients (53%) were from middle class family with occupation of private service (26.66%) and farmer (20%). Positive family history was reported in 20% of patients. Regarding the precipitating factors, majority of patients (83.3%) were related to high carbohydrate meal, 56.67% related to temperature, 41.67% to exercise. Flaccid muscle weakness with variables muscle power (MRC grade 4/5 to 2/5 in 60% and 1/5 to 0/5 in 40%) was found. Cerebellar functions, all modalities of sensations and functions of cranial nerves were intact in all patients. In this series, laboratory investigations revealed reduced serum potassium level (<3mmol/l) in 90% of patients. Serum potassium value >5.5mmol/l was found in only 3.33% of patients. Creatine kinase (MM) was raised in 23% of the patients and Thyroid stimulating hormone (TSH) level was 0.8-2mmol/l in 6% of the patients. More than half of the patients (56%) showed variable ECG changes. Impaired nerve conduction function was found in 28.00%. So, careful history taking, meticulous clinical examination and simple laboratory investigations is sufficient to make a prompt diagnosis and rapid management of patients with periodic paralysis.

Contrast induced nephropathy (CIN), an acute decline in renal function after the administration of intravenous contrast in the absence of other causes, is the third leading cause of acute renal failure in hospitalized patients. Antioxidant N-acetylcysteine prevents acute contrast nephrotoxicity in patients with impaired renal function who underwent coronary angiography (CAG) and percutaneous coronary intervention (PCI). Hydration is the cornerstone in preventing CIN. N-acetylcysteine has additive preventive affect. We compared N-acetylcysteine plus hydration with hydration alone in preventing CIN. Patients were assigned to receive either premedication with hydration with normal saline (1ml/kg/hour-12 hour before and 12 hour after CAG and intravenous PCI) alone or to receive both hydration and oral N acetylcysteine (600mg bid for 2 days, starting day before CAG and PCI). Main out come was occurrence of ≥25% or ≥0.5mg/dl increase in serum creatinine level within 24 to 48 hours after contrast administration; change in creatinine clearance and serum creatinine level. Six patients (12%) of hydration group i.e. Group A and none of the patients of N-acetylcysteine All group i.e. Group B develop CIN (p=0.012). Baseline serum creatinine level was slightly higher in N-acetylcysteine group than hydration group (1.52±0.32 and 1.44±0.22). After 24 hours of CAG and PCI serum creatinine level lower than base line in N-acetylcysteine group but slightly higher than base line in hydration group (1.42±0.39 and 1.51±0.38). Difference in serum creatinine in both the groups were statistically significant (p=0.006 in N-acetylcysteine group and p=0.029 in hydration group). Creatinine clearance rate significantly improved in N-acetylcysteine group after coronary intervention. In conclusion, N-acetylcysteine and hydration prevent CIN better than hydration alone in high risk patients.

Contrast induced nephropathy is the third leading cause of acute renal failure in hospitalized patients. However, its incidence and risk factors in Bangladeshi population undergoing coronary angiogram and percutaneous coronary intervention is not clear. This study was to assess the incidence of contrast induced nephropathy in patients, with or without pre existing renal impairment, undergoing coronary angiogram and percutaneous transluminal coronary angioplasty in Bangladeshi population. Two hundred patients undergoing coronary angiogram and percutaneous were included in the study .Patients having history of contrast allergy and patients on renal dialysis were excluded from the study. Serum creatinine level was estimated before the undergoing procedure. Creatinine clearance rate was calculated by applying Cockcroft Gault formula to the preprocedure serum creatinine level. Patients were assigned to one of the two groups, that is with or without chronic renal insufficiency. Serum creatinine levels were again estimated at the end of 24 hours of contrast exposure. The rise of serum creatinine by ≥0.5mg/dl or ≥25% occurring within 24 hours of contrast administration was defined as contrast induced nephropathy. The incidences of Contrast induced nephropathy (CIN) in these groups were compared. We tried to analyze whether there is relation between the incidence of CIN with contrast volume, chronic renal insufficiency, diabetes mellitus, and coronary procedures undergone. We enrolled 120 pre existing chronic renal insufficiency patients and 80 patients without pre existing chronic renal insufficiency. In this study 21.7% of pre existing chronic renal insufficiency group and 6.3% of no pre existing chronic renal insufficiency group developed contrast induced nephropathy (p=0.003). Contrast induced nephropathy is an iatrogenic disorder and pre existing renal impairment is one of the risk factors for developing contrast induced nephropathy.

Development of perilobular hepatic fibrosis in rabbits after experimental ligation of the common bile duct was studied by microscopy. Twelve hours after the ligation, the lobular boundaries assumed prominence by appearance of row(s) of congested sinusoids around the distended perilobular canals of Hering. Seven days later, the lobular laminae limitans around such canals of Hering revealed myxomatous ballooning degeneration forming well defined inter-lobular bands (ILBs). On day 15 post-ligation, the residual sinusoidal endothelial-lining cells in the ILBs manifested hyper chromasia and occasional mitotic activity. It was followed, on days 25 and 35, by proliferation (hyperplasia) of the sinusoidal endothelium cells forming the portal tract like fibrotic tissue in the perilobular bands. These findings, showed the course of interlobular bridging necrosis along the bile preductules at the lobular circumferences and subsequently indigenous origin of the fibrotic tissue in the ILBs from the residual cells in the affected parenchyma independent of the portal tracts.
