Trend and Epidemiological Profile of Dengue Fever/Dengue Haemorrhagic Fever in Ahmedabad City, Gujarat, India

Introduction: Correct perceptions of young Dental and Unani students towards Reproductive and Sexually Transmitted Infections (RTIs and STIs) Management are not only essential; for the prevention of Occupational Exposures to RTIs and STIs( including HIV/AIDS) to them from their Clinical Practice, but also for effective management of such cases in their future clinical practice as evident from their Improper attitudes currently existing in literature. Objective: To understand In-depth about perceptions towards RTI and STI Management among Dental Students and Unani Medical College students in their colleges study curriculums. Method : A Cross sectional Bi-centric Study was done at 2 Institutions on 1000 Students (500 Dental( BDS) and 500 Unani(BUMS) students of all batches for 7 months from Jan 2018 to July 2018. The Students Qualitative data was obtained by Semi-structured E-questionnaire sent to them via emails. Key RTIs and STIs were included in this study such as: HIV, Hepatitis B, Hepatitis C , Human Pappiloma Virus (HPV), Chlamydia, Gonorrhoea etc. The data were analyzed by software Epi-info(version 7.2.2.2). Results: The Dental students of (BDS) had significantly better knowledge and attitudes as to compared Unani (BUMS ) students( p< 0.001) in both the understanding of importance of socio-cultural factors in RTI/STI causation and key diseases management strategy towards RTI/STI in their respective setups. Conclusion: RTI and STI management needs priority both in BDS as well as BUMS courses. However BUMS-Unani students needs improvement knowledge and proper attitudes towards RTI/ STI management from their Study Curriculum. This attitude issue needs more consideration in their clinical teaching.

Role of hybrid operating room in surgery for the right atrial thrombus, pulmonary thrombi, and ventricular septal rupture after myocardial infarction.

Free‑floating right heart thrombi are uncommon and need emergency treatment in view of their tendency to dislodge and cause pulmonary embolism. We report a successful surgical management of a patient who had large mobile right atrial thrombus, bilateral pulmonary thrombi, coronary artery disease, and postmyocardial infarction ventricular septal rupture (VSR). The patient underwent coronary angiography, inferior vena cava filter placement, removal of thrombi from the right atrium and pulmonary arteries, repair of VSR, and coronary artery bypass graft surgery in a hybrid operating room.

Cardiac surgery during pregnancy: Continuous fetal monitoring using umbilical artery Doppler flow velocity indices.

The fetal death rate associated with cardiac surgery with cardiopulmonary bypass (CPB) is as high as 9.5‑29%. We report continuous monitoring of fetal heart rate and umbilical artery flow‑velocity waveforms by transvaginal ultrasonography and their analyses in relation to events of the CPB in two cases in second trimester of pregnancy undergoing mitral valve replacement. Our findings suggest that the transition of circulation from corporeal to extracorporeal is the most important event during surgery; the associated decrease in mean arterial pressure (MAP) at this stage potentially has deleterious effects on the fetus, which get aggravated with the use of vasopressors. We suggest careful management of CPB at this stage, which include partial controlled CPB at initiation and gradual transition to full CPB; this strategy maintains high MAP and avoids the use of vasopressors. Maternal and fetal monitoring can timely recognize the potential problems and provide window for the required treatment.

Predictors of operative mortality following primary coronary artery bypass surgery.

BACKGROUND: Although quality assessment of coronary artery patients can be done by 30 days risk-adjusted operative mortality, it is still insufficient to study the outcome after primary coronary artery bypass graft surgery (CABG). In our study, we attempted to determine the factors, which can help predict operative mortality before and after CABG. METHODS: The study population consisted of 1000 prospective patients who underwent primary isolated CABG. Assessment was done by dividing the patients into two groups, i.e. non-survivors ( n= 12) and survivors ( n= 988). Data were analyzed using both univariate and multivariate models. RESULTS: On univariate analysis, recent acute myocardial infarction, intra-aortic balloon counterpulsation (IABC), left ventricular ejection fraction (LVEF) <25%, ventilator-associated pneumonia (VAP), tracheostomy, re-exploration, ventricular arrhythmias, low cardiac output (CO), multiple blood transfusions, post-operative renal dysfunction and longer intensive care unit and hospital stay were found as risk factors for mortality. Multivariate analysis showed that LVEF <25%,VAP, ventricular arrhythmias and low CO independently predicted mortality. Prior knowledge of these risk factors can help not only in predicting the outcome and the risks but also helps to plan the surgical and post-operative course of the patients to improve the morbidity and mortality. CONCLUSION: Our data suggest that operative mortality can be predicted prior to and after surgery considering factors such as LVEF, use of IABC, onset of ventricular arrhythmias and low CO.

Post-operative outcome of ventricular reshaping by septal exclusion in patients with severe left ventricular dysfunction.

BACKGROUND: Post-myocardial infarction, anteroseptal dysfunction or akinesia is treated by septal reshaping to improve the surgical outcome in patients with severe left ventricular dysfunction. METHODS AND RESULTS: Between February 2003 to December 2003, 30 consecutive patients with previous anterior wall myocardial infarction and severe ventricular dysfunction underwent septal reshaping. All the dyskinetic and akinetic septal areas were excluded using an oval dacron patch which was sutured from the healthy septal area to the anterior wall, resulting in formation of a new apex. There were two mortalities in the group. After a mean follow-up of 4.2 +/- 1.6 months (1-7 months) it was seen that this procedure resulted in significant reduction of ventricular volume, increase in ejection fraction, an improvement in New York Heart Association class from 2.9 +/- 1.1 to 1.7 +/- 0.3, and a better apical geometry. CONCLUSIONS: In selected patients with left anterior descending artery occlusion resulting in anteroseptal dyskinesia or akinesia, septal exclusion technique provides good clinical and morphological results with significant improvement in left ventricular function.

Beating heart versus conventional reoperative coronary artery bypass surgery.

BACKGROUND: The incidence of reoperative coronary artery bypass grafting is increasing with an increase in the number of patients undergoing coronary artery bypass surgery. The clinical outcome of redo coronary artery bypass grafting without cardiopulmonary bypass and conventional coronary artery bypass grafting using cardiopulmonary bypass are different. METHODS AND RESULTS: We compared clinical parameters in patients who underwent off-pump (n=156) versus on-pump (n=194) redo coronary artery bypass grafting performed between January 1995 and December 2001 in our institute, to determine if off-pump surgery has improved the surgical outcome of redo coronary artery bypass grafting and emerged as an ideal technique. Patients who underwent on-pump redo surgery required more postoperative blood transfusion (86.53% on-pump v. 12.82% off-pump. p=0.001), prolonged ventilatory support (>24 hours) (16.49% on-pump v. 7.7% off-pump, p=0.021) and higher inotropic support (23.71% on-pump v. 10.89% off-pump, p=0.003). On-pump redo coronary artery bypass grafting was also associated with a prolonged stay in the intensive care unit (40+/-6.2 hours on-pump v. 20+/-4.1 hours off-pump, p=0.001) and longer hospital stay (9+/-4.2 days on-pump v. 5+/-3.4 days off-pump, p=0.001). In-hospital mortality was higher in on-pump patients than in off-pump ones (7.7% v. 3.2%); however, this was not statistically significant (p=0.114). CONCLUSIONS: Off-pump redo coronary artery bypass grafting is a safe method of myocardial revascularization with lower operative morbidity and mortality, less requirement of blood products and early hospital discharge, compared with conventional on-pump redo coronary artery bypass grafting.
