Prevalence of Underweight and Effect of Nutritional Status on Academic Performance of Primary School Children in Chapainawabganj District, Bangladesh

The high prevalence of underweight among children is a serious health concern in Bangladesh. Nutritional status influences students' academic performance directly or indirectly. This study aimed to determine factors that affect the academic performance of students in primary schools. Methods: Data were collected from several schools and madrasahs in Chapainawabganj district, Bangladesh using multistage stratified sampling with proportional allocation technique. Results: The prevalence of underweight children was 32.3%, with 43.0% of them being girls and 21.4% boys. Multiple logistic regression analysis demonstrated that normal weight children were more likely (p3.50) than underweight children. Children with gestational age of 39 to 41 weeks were more likely to obtain good results than those whose gestational age was 37 and 38 weeks. Children who were breastfed for 3.50) compared to their counterparts. Children whose parents had a higher income or higher education had a significantly better chance of obtaining good results compared to their counterparts. Conclusion: These results suggest that childhood nutritional status, parents' education and economic level are significant common factors which affect children's academic performance. Consequently, under-nutrition and poverty can be considered as the major problems for good academic performance of Bangladeshi children and requires attention

Off Pump CABG along with Resection of Giant Thymoma : A Case Report.

Coronary artery disease is the most common form of heart disease and the single most important cause of premature death world-wide. Thymomas are anterior mediastinal neoplasms, characterized by epithelial cells and lymphocytes. Although they are often encapsulated and well differentiated tumors, they can show local invasion, pleural invasion or extrathoracic metastasis. In this article, we report the case of a rare patient who underwent thymectomy along with off-pump coronary artery bypass graft surgery.

War and the Development of Cardiac Surgery.

Despite all the devastating effects, wars have made some very significant positive impact in the development of cardiac surgery. Heart is an organ that cannot be stopped even for a minute, there by making it very difficult for the surgeons to operate. The wars of the Twentieth Century, particularly the two Great wars produced a significant number of patients with heart injury to reach surgeons’ operating tables. This gave the surgeons a unique opportunity to study, operate, practice and research cardiac surgical patients. Notable names including Wilfred Bigelow, Walton Lillehei, John Gibbon, Christian Cabrol, Vasilii Kolessov and Alexander Vishnevsky all were world war veterans and utilized their wartime experience later on in the development of cardiac surgery. Had there not been the two great wars, the development of cardiac surgery would have been delayed probably by years.

An experimental study of phage mediated bactericidal selection & emergence of the El Tor Vibrio cholerae.

Background & objectives: Factor causing the elimination of the classical biotype of Vibrio cholerae O1, and its replacement by the El Tor biotype causing the 7th cholera pandemic are unclear. Possible ability of the El Tor strains to adapt better than the classical strains to undefined environmental forces have been largely implicated for the change. Here we describe an environmental bacteriophage designated JSF9 which might have contributed to the range of factors. Methods: Competition assays were conducted in the infant mice model and in microcosms between representative El Tor and classical biotype strains in the absence or in the presence of JSF9 phage. Results: The JSF9 phage was found to kill classical strains and favour enrichment of El Tor strains, when mixtures containing strains of the two biotypes and JSF9 phage were subjected to alternate passage in infant mice and in samples of environmental water. Spontaneous derivatives of the classical biotype strains, as well as transposon mutants which developed resistance to JSF9 phage were found to be defective in colonization in the infant mouse model. Interpretation & conclusions: These results suggest that in addition to other factors, the inherent ability of El Tor biotype strains to evade predation by JSF9 or similar phages which kill classical biotype strains, might have enhanced the emergence of El Tor strains as the predominant pandemic biotype.

Patients with Left Ventricular (LV) Dysfunction: Is OPCAB Advantageous over Conventional CABG in our settings.

Objective: Off-pump CABG (OPCAB) is a well established surgical procedure in Bangladesh now. Majority of Bangladeshi patients having CABG are undergoing OPCAB procedures these days. Patients with left ventricular dysfunction are known to be particularly at risk of complications after surgical coronary revascularization. Off-pump procedure can be considered in these patients, avoiding the potentially damaging effect of cardiopulmonary bypass (CPB). Patients with left ventricular dysfunction are thus thought to be ideal OPCAB candidates. This study is undertaken to check the advantage of OPCAB over conventional CABG of Bangladeshi patients with left ventricular dysfunction. Methods: This is a prospective clinical trial done in National Institute of Cardiovascular Diseases (NICVD), Dhaka during the period of January 2006 to Dec 2007. Among the 52 patients 26 patients underwent OPCAB with preoperative ejection fraction (EF) 35.2±3.2% and rest 26 patients had conventional bypass (CCABG) with preoperative EF 33.4±3.8%. Different variables were evaluated and compared. Echocardiography was used both pre and postoperatively to assess the LVEF, LVIDd and LVIDs and regional wall motion abnormality and to assess the presence or absence of ischemia or infarction. Data were collected by interview schedule and checklist. Data were analyzed by standard statistical methods. Results: In this small series of patients with left ventricular dysfunction, off-pump CABG was carried out with good early outcome; with low mortality and morbidity and significant improvement in postoperative left ventricular function. There was no significant difference between the groups in terms of change in EF, LVIDd and LVIDs. Conclusion: From this study it can be concluded that both the surgical strategies improved the myocardial function and early outcome in patients with left ventricular dysfunction. However OPCAB surgery has a somewhat better result regarding ventilation time and ICU stay. Thus both OPCAB and on pump surgery can be performed safely and effectively in patients with left ventricular dysfunction with good results and low mortality.

Feeding pattern of children under two years in some selected villages.

Objective: The present study was aimed to find out the feeding pattern of children less than two years of age in rural areas. Methodology: The study area consisting of three villages of Muradnagar Upazila under the district of Comilla. Families having children under-two years of age were included in the study. A total number of 54 families finally entered in the study. Respondents were interviewed using structured questionnaire regarding initiation of breast feeding of the new born, their breast feeding pattern and weaning of the children. Socio-demographic characteristics of the respondents were recorded. Data were presented as number and percentage. Results: Out of the 54 respondents 52 (96.3%) were mothers and 2 (3.7%) fathers. Of the total 50 (92.6%) respondents was housewife. Among 54 respondents 36 (66.7%) were in the age group of 18 to 25 years. Thirteen (24.1%) respondents were illiterate and among the rest 27 (50%) had primary level and 2 (3.7%) had bachelor level of education. Twenty six (48.1%) respondents said newborns were given breast milk first and rest 28 (51.9%) mentioned about giving of honey, cow’s milk and sweet water made of sugar or sugar product. Twelve (22.2%) mothers started breast feeding within 15 minutes after birth, 28 (51.9%) after 1 hour or more. Twenty one 21 (38.9%) had given exclusive breast feeding to the children for six months and 33 (61.1%) given additional stuff during that time. Thirty (55.6%) mothers started weaning before reaching 6 months of age, 13 (24.0%) between 6 months to 12 months and 1 (1.9%) started after 12 months. Commonly used weaning foods were rice, shuzi, khichuri, cow’s milk, infant formula, fish, egg, meat, honey, vegetables and fruits especially banana. Conclusion: The data suggest wide range of variability still exists in allowing colostrums to the newborn, breast feeding itself and also weaning practice.

Hyper reactive malarial splenomegaly (HMS).

Hyper reactive malarial splenomegaly (HMS) is a relatively rare chronic complication of malaria. Previous name of the disease was Tropical splenomegaly syndrome (TSS). It is seen in endemic zone of malaria. In Bangladesh it is very rare. It is more prevalent in Africa, India, Sri Lanka, Thailand etc. It is due to abnormal immune response to malaria. Recently we got a typical case of HMS in our pediatric department of Community Based Medical College Hospital (CBMCH) Mymensingh. The patient, a seven years old boy came from Haluaghat, Mymensingh, which is a hyper endemic zone of malaria. The boy had history of repeated attack of malaria with huge chronic splenomegaly for five years. Antibody to malaria was positive & titer was markedly raised. Other causes of massive splenomegaly namely chronic Kala azar, Typhoid, congenital hemolytic anemia, Leukaemia, Lymphoma etc were excluded by laboratory examination. The boy was discharged with malaria prophylaxis for a long time & advised to come to our unit every month for further follow up.

Molecular comparison of toxigenic clinical & non-toxigenic environmental strains of Vibrio cholerae O1 Ogawa isolated during an outbreak of cholera in south India.

BACKGROUND & OBJECTIVES: While investigating a cholera outbreak in south India, toxigenic and nontoxigenic strains of Vibrio cholerae O1 were isolated from patients and from the environment, respectively. This study was performed to compare the genetic relatedness of the patient and environmental strains to determine clonal relationships among these strains and thereby determine the source of the cholera outbreak. METHODS: The 16 strains of V. cholerae isolated from hospitalized patients and 8 environmental V. cholerae strains isolated from the environment were phenotypically and genotypically characterized using a variety of standard techniques. RESULTS: Sixteen toxigenic clinical strains and 2 nontoxigenic environmental strains belonged to O1 serogroup, Ogawa serotype and El Tor biotype. The remaining 6 nontoxigenic environmental strains were classified as non-O1, non-O139 V. cholerae. The drug resistance pattern of the clinical and environmental strains of V. cholerae showed marked differences with the patient strains being resistant to more number of drugs as compared to the environmental strains. DNA fingerprinting of the strains showed considerable diversity between toxigenic clinical and nontoxigenic environmental O1 Ogawa isolates and between the O1 and non-O1, non-O139 isolates. INTERPRETATION & CONCLUSION: In this outbreak of cholera, the O1 strains of V. cholerae from clinical and environmental sources belonged to two different clones and the environmental strains could perhaps be the future cholera outbreak causing clones.
