Abstract Background Tobacco smoking issues in developing countries are usually taught non-systematically as and when the topic arose. The World Health Organisation and Global Health Professional Student Survey (GHPSS) have suggested introducing a separate integrated tobacco module into medical school curricula. Our aim was to assess medical students' tobacco smoking habits, their practices towards patients' smoking habits and attitude towards teaching about smoking in medical schools. Methods A cross-sectional questionnaire survey was carried out among final year undergraduate medical students in Malaysia, India, Nepal, Pakistan, and Bangladesh. An anonymous, self-administered questionnaire included items on demographic information, students' current practices about patients' tobacco smoking habits, their perception towards tobacco education in medical schools on a five point Likert scale. Questions about tobacco smoking habits were adapted from GHPSS questionnaire. An 'ever smoker' was defined as one who had smoked during lifetime, even if had tried a few puffs once or twice. 'Current smoker' was defined as those who had smoked tobacco product on one or more days in the preceding month of the survey. Descriptive statistics were calculated. Results Overall response rate was 81.6% (922/1130). Median age was 22 years while 50.7% were males and 48.2% were females. The overall prevalence of 'ever smokers' and 'current smokers' was 31.7% and 13.1% respectively. A majority (> 80%) of students asked the patients about their smoking habits during clinical postings/clerkships. Only a third of them did counselling, and assessed the patients' willingness to quit. Majority of the students agreed about doctors' role in tobacco control as being role models, competence in smoking cessation methods, counseling, and the need for training about tobacco cessation in medical schools. About 50% agreed that current curriculum teaches about tobacco smoking but not systematically and should be included as a separate module. Majority of the students indicated that topics about health effects, nicotine addiction and its treatment, counselling, prevention of relapse were important or very important in training about tobacco smoking. Conclusion Medical educators should consider revising medical curricula to improve training about tobacco smoking cessation in medical schools. Our results should be supported by surveys from other medical schools in developing countries of Asia.

Background: Vernix caseosa is a naturally occurring substance covering the skin of the newborn babies. Chemical composition of Vernix caseosa has been studied. But the antibacterial properties have not been explored phenotypically. There has been only a few studies related to the properties of Vernix caseosa (VC) and most of them focused on deciphering the chemical nature of VC. These studies found that VC has enzymes such as lysozyme, cathelicidin, lactoferrin, defencins, etc, but no study has proved their presence phenotypically. Aim: To know the anti-bacterial and mechanical barrier properties of VC. Materials and Methods: A cross-sectional study done at Government Lady Goshen Hospital, Mangalore, India. Subjects- 63 healthy infants born by LSCS (Lower Segment Caesaren Section) (Confidence interval- 95%, Power- 90%). In lab, sterility of Vernix caseosa was determined. Lawn culture of S.aureus and E.coli on nutrient agar was done and wells were made in it. Vernix broth was prepared using Tween 80 and was put into the well. It was incubated overnight at 37°C and observed for area of Decreased Bacterial Growth (DBG) around the well. Filter papers impregnated with VC were used for testing for mechanical barrier properties. Statistical Analysis: Data was entered in SPSS 12.0 version and analysed. The zone of inhibition (in mm) in case of bacterial growth was expressed as mean with standard deviation. Student's independent t-test was used to compare the means across the groups (males and females). Results: There was no significant difference in the anti-bacterial property based on gender. DBG {mean (SD)} for E.coli and S.aureus was 18.06 mm (1.56) and 13.34 mm (1.94) respectively (p-value <0.000). Result for mechanical barrier was inconclusive due to limitations explained in the article. Conclusion: Vernix caseosa has antibacterial properties. But further studies are needed to explore the mechanical barrier properties against bacteria. [ABSTRACT FROM AUTHOR]
