Resumo: Neste relato buscamos apresentar uma experiência realizada durante um projeto denominado Cinemática-Cinema e Debate. O objetivo central do relato é descrever como ocorreu a experiência. O objetivo do projeto foi de promover o que denominamos de “dessilenciamento”, ou seja, promover a argumentação dos participantes, professores e estudantes, acerca de temas apresentados em sessões fílmicas com temáticas relativas às práticas escolares docentes. O projeto, que optou por utilizar uma abordagem qualitativa de pesquisa, contou com a participação de dois pesquisadores, um orientado e uma bolsista que organizavam as sessões para que os debates pudessem ocorrer. Nossas leituras e fundamentações teóricas ao longo da experiência se basearam em investigações de Coelho e Viana (2013), Viana (2009; 2010; 2011) e Viana, Rosa e Orey (2011) e auxiliaram a estruturar as sessões em busca do desenvolvimento de criticidade e “dessilenciamento”. Os principais resultados foram proporcionar espaços para debates, a partir de filmes que envolviam o cotidiano de professores, envolver a comunidade acadêmica para exercitar outros olhares e dar vozes aos estudantes por meio de suas argumentações.Palavras-chave: “Dessilenciamento”; Cinema; Argumentação.

Resumo: Analisamos na tradução feita para o inglês, por Elisabeth Carter, em 1739, a obra de Francesco Algarotti “Sir Isaac Newton’s philosophy explain’d for the use of ladies. In six dialogues on light and colours”. Buscamos compreender os aspectos que a caracterizam como uma publicação para damas e identificar possíveis questões de gênero. Identificamos na obra uma tendência machista na ciência e elementos que evidenciam um imaginário de que a mulher não teria as qualidades necessárias para compreender a ciência, elementos esses coerentes com a transição de um período em que as mulheres eram consideradas inferiores em todos os aspectos para um outro no qual a construção do papel materno aparece como fundante de uma concepção de mulher não mais inferior, mas fundamentalmente diferente do homem e com papeis complementares a ele. Podemos dizer que esses imaginários podem influenciar as possibilidades de participação das mulheres na empreitada científica.Palavras-chave: Educação em Ciências; História da Ciência; Ciência e Sociedade (Gênero). History of Science and gender relations: a publication of “Sir Isaac Newton’s philosophy explained for de use of ladies. In six dialogues on light and colours”Abstract: We analyze Elisabeth Carter's 1739 translation of Francesco Algarotti's "Sir Isaac Newton's philosophy explain'd for the use of ladies. In six dialogues on light and colors. "We seek to understand the aspects that characterize it as a publication for ladies and to identify possible gender issues. We identified in the work a macho tendency in science and elements that evidence an imaginary that women would not have the qualities necessary to understand science, elements that are consistent with the transition from a period in which women were considered inferior in all respects to a another in which the construction of the maternal role appears as the founder of a conception of woman no longer inferior but fundamentally different from man and with roles complementary to him. We can say that these imaginary can influence the possibilities of participation of women in the scientific enterprise.Keywords: Science Education, History of Science; Science and Society (Gender).

Published: January 2019

Introduction: Inappropriate use of antibiotic may create several problems including emergence of drug resistant microorganisms, the rising costs of health-care services and the development of side effects. Misconceptions regarding antibiotic can lead to misuse of antibiotics. So, consumers’ knowledge towards antibiotic may play a vital role in the success of treatment process.
Objectives: To investigate the level of basic knowledge towards antibiotics among troops of Bangladesh Army and their relatives in Rangpur, Bangladesh.
Materials and Methods: This cross-sectional study was conducted from January to March 2015 for 12 weeks using the structured questionnaire involving 389 respondents attending outdoor of various departments of Combined Military Hospital (CMH), Rangpur. A random knowledge score system was used to assess basic knowledge based on the answers provided.
Results: The mean age of the respondents was 30.434 years (SD=6.5365) with male (53.47%) predominance. Out of 389 respondents, 219(56.30%) respondents had a moderate level of knowledge. Most of the respondents (89.72%) could correctly identify that antibiotics are indicated for the treatment of bacterial infections. However, 348(89.46%) respondents incorrectly thought that antibiotics are also used to treat viral infections. Most of the respondents wrongly believed that antibiotics are indicated to relieve pain (68.69%) and reduce fever (77.38%). About 270(69.41%) respondents were aware of antibiotic resistance phenomena in relation to overuse of antibiotics. Age, sex and educational level were significantly associated with knowledge towards antibiotic.
Conclusion: Educational intervention is needed to promote prudent use of antibiotic.

Authors: Perveen Rosy , Islam AFMS , Rahman Habibur , Khan Ruksana P 
Published: January 2019

Introduction: Acute appendicitis is one of the most common causes of abdominal pain of adult patients referred to the emergency department. Despite its prevalence, the diagnosis of appendicitis can be elusive and fraught with pitfalls because of the absence of a pathognomonic sign or symptom and the poor predictive value of laboratory testing. So following the significant advances in accuracy, ultrasonography has become an important part of the modern work-up of acute appendicitis.
Objective: To evaluate the role and accuracy of ultrasonography in the diagnosis of acute appendicitis. Materials and Methods: A total number of 110 cases (65 men and 45 women), with clinical suspicion of appendicitis, were subjected to abdominal ultrasonographic examination. All ultrasonographic positive cases and a few of ultrasonographic negative cases were subjected to operative intervention.The accuracy of ultrasonography in the diagnosis of appendicitis was compared with the clinical diagnosis, operative findings and histopathological examination reports. The statistical analysis was done by using SPSS10.
Results: Among 110 cases, 77 cases were sonographically positive for appendicitis and 5 cases were appendicular masses. The cardinal signs were right lower abdominal tenderness, rebound tenderness and positive Rovsing’s sign. The specificity of Ultrasound was 74.28%, sensitivity 90.66%, positive predictive value 88.31%, negative predictive value 78.79% and accuracy was 85.45% in the diagnosis of acute appendicitis.
Conclusion So far the cost reduction of treatment and negative laparotomies are concerned, the ultrasonography is still an useful tool in the diagnosis of appendicitis in spite of more recent investigations like CT abdomen and Laparoscopy.

Authors: Tabassum Rehnuma , Mithun Sangita , Irfan SM Nurul 
Published: January 2019

Introduction: Hypertension is independent and the most powerful predictor of cardiovascular morbidity and mortality. Sympathetic overdrive may be related to essential hypertension. Heart Rate Variability (HRV) analysis is one of the most quantitative markers of autonomic activity in hypertensive patients.
Objective: To assess the cardiac autonomic nerve function status by heart rate variability in essential hypertension.
Materials and Methods: This cross sectional study was carried out to observe the HRV in 60 hypertensive male patients with age ranging from 40-60 years (group B) in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU) from 1st July 2008 to 30th June 2009. Based on treatment, hypertensive patients were divided into B1 (untreated patients on their 1st day of diagnosis) and B2 (patients with antihypertensive therapy for less than 5 years). For comparison, 30 apparently healthy normotensive subjects (group A) matched by age sex were also studied. The study group was selected from the Out Patient Department of Cardiology, BSMMU, Dhaka and the control group was selected by personal contact. Heart Rate Variability parameters were assessed by Polygraph (RMS Polyrite D, version2.2) and for statistical analysis Independent sample t-test, One-way ANOVA test, Chi-square test and Pearson’s correlation coefficient tests were done as applicable.
Results: LF/HF(Low Frequency/High Frequency) ratio and LF norm (normalized unit) were significantly (p<0.001) higher and HF norm was significantly (p<0.001) lower in untreated hypertensive patients in comparison to those of healthy normotensive subjects. parameters were observed between treated hypertensive and healthy control subjects. The LF/HF ratio and LF norm showed positive correlations and HF norm showed negative correlations with SBP (systolic blood pressure) and DBP (diastolic blood pressure) in both the hypertensive groups. However, all these findings were more marked in untreated hypertensive patients than those of treated group.
Conclusion: Hypertensive patients may have sympathovagal imbalance and is usually characterized by higher sympathetic as well as lower vagal modulation of the heart rate.

Authors: Hasan Md Amirul , Quashem Md Abul , Jahan Sharmin 
Published: January 2019

Introduction: The Mean Platelet Volume (MPV) is a marker of platelet size with increased platelet activation. An elevated MPV is associated with major cardiac adverse events after Coronary Artery Bypass Graft (CABG) surgery. Effect of preoperative MPV on outcome of in-hospital patients after coronary artery bypass graft surgery was investigated in this study.
Objective: To investigate the association of preoperative MPV with in-hospital outcome of patients after CABG surgery.
Materials and Methods: An observational prospective study was carried out in the Department of Cardiovascular Surgery, National Institute of Cardiovascular Diseases (NICVD), Dhaka during the period from July 2012 to June 2014. Preoperative mean platelet volume was obtained prospectively in 81 consecutive patients undergoing conventional coronary artery bypass surgery. The patients were divided into two groups according to normal and elevated MPV at 10.60 femtolitre (fL) cut off level. Postoperative mortality and major adverse events were recorded in the early postoperative period.
Results: Combined adverse events including post operative Myocardial Infarction (MI), arrhythmia, bleeding and death occurred in 27 patients (33.3%) during the early follow-up. The preoperative mean platelet volume levels were found to be associated with postoperative adverse events (p<0.05). In multivariate logistic regression models, the preoperative mean platelet volume levels was found strong independent predictor of combined adverse events after surgery (OR 1.968, p=0.008).
Conclusion: Mean platelet volume is simple, readily available and cost effective tool and useful in predicting the postoperative adverse events in patients undergoing coronary artery bypass graft surgery.

Published: January 2019

Introduction: Irritable bowel Syndrome (IBS) is a functional disorder of abdominal pain or discomfort associated with altered bowel habit. Microscopic colitis is a chronic inflammatory condition associated with non bloody diarrhoea and characteristic histological finding. The subset of diarrhoea predominant IBS is having similarity in presentation with microscopic colitis.
Objective: To assess the prevalence and characteristics of microscopic colitis in Diarrhoea predominant Irritable Bowel Syndrome (IBS-D).
Materials and Methods: This observational study was conducted at the department of Gastroenterology, Combined Military Hospital, Dhaka during the period of January 2011 to June 2011. Initially 100 cases of diarrhoea predominant IBS who met Rome III criteria were included. Among those 100 cases, 57 were male and 43 were female. Mean age was 46 years ±2.8 SD(range 18-72). Six patients were subsequently excluded because of some macroscopic abnormalities at colonoscopy. Finally 94 patients of clinical IBS-D whose colonoscopy were normal, biopsy specimens were taken from caecum, transverse colon, descending colon, sigmoid and rectum. Microscopic colitis was diagnosed on the basis of evidence of increased intraepithelial lymphocytes of ≥20/100 inter cryptal epithelial cells and infiltration of lamina propria by mixed inflammatory cells. Overlap of other symptoms between Microscopic Colitis (MC) and IBS-D were also evaluated. Results: Among the 94 patients of clinical IBS-D, 23(24%) patients were histologically proved to have microscopic colitis. Besides Rome III criteria, there was significant overlap of other symptoms. Occasional fever and infrequent arthralgia 7% and 26% vs 4% respectively) but tenesmus, passage of excessive mucus and heart- burn were more prevalent in IBS-D than MC (35% vs 13%, 32% vs 4% and 32 vs 9% respectively). Among the 23 cases of MC, 13(57%) patients were female and 10(43%) patients were male. Mean age of microscopic colitis was 56 years ±2.6 SD (range 25-72). Regarding subtypes of microscopic colitis, 21(91%) patients had lymphocytic colitis (LC) and 2 (9%) patients had collagenous colitis (CC). Of the lymphocytic colitis 11 were female and 10 were male and of the 02 cases of collagenous colitis all were female. MC affected mostly the transverse colonie 11(48%) cases and the next common site was caecum ie 8(35%) cases.
Conclusion: A good percentage of diarrhoea predominant IBS are actually having microscopic colitis. MC is more common in female and elderly persons. In all elderly patients of IBS-D full colonoscopy should be done and biopsy should be taken from multiple sites to exclude microscopic colitis.
