The status of pediatric cardiology at a tertiary center in Lebanon.

PROBLEM: Cardiac disease, both congenital and acquired, contributes significantly to morbidity and mortality in children. METHODS: This article describes the status of pediatric cardiology at the Children's Heart Center in the American University of Beirut Medical Center. It addresses the available clinical services as well as the research and educational activities that are present at a tertiary center in Lebanon, a developing country with a population of 4 million. RESULTS: Lebanon has witnessed major developments in the field of pediatric cardiology over the past few years. About 650 babies are born with heart disease every year, with more than 425 needing treatment. Nearly all types of interventional catheterization procedures are currently being performed. About 300 open and closed pediatric cardiac surgeries are performed per year in Lebanon. In 2008, the in-hospital surgical mortality rate at our center was 2.6%, reflecting the good level of care in the treatment of children with congenital heart disease (CHD) in Lebanon. Basic research in the field of pediatric cardiology is emerging at our center. Our team has been studying the effect of chronic hypoxemia on the neonatal myocardium in an animal model of chronic hypoxia, as well as the study of molecular basis of CHD. CONCLUSION: Appropriate identification of cardiac disease, its epidemiology, and outcome is of utmost importance in guiding adequate care. Centralization of facilities is important to improve results and level of care.

Prevalence of asthma, allergic rhinitis and eczema among Lebanese adolescents.

OBJECTIVE: Studies on allergic diseases remain scarce in Lebanon. The aim of the present study was to determine prevalence and characteristics of asthma, allergic rhinitis and eczema among Lebanese school children. METHODS: The study was cross-sectional in design performed on a convenient sample of 3,115 students (13-14 yr) selected from 13 schools in 5 Lebanese provinces. Students were asked to complete the Arabic version of the International Study of Asthma and Allergies in Childhood questionnaire. Logistic regression was performed to assess the characteristics of having asthma, allergic rhinitis and eczema in the past year. RESULTS: The prevalence of ever having asthma, rhinitis and eczema was 8.3%, 45.2% and 12.8% respectively, while the prevalence of the symptoms of these diseases in the past year was 24.1%, 38.6% and 20.9%, respectively. Residing in the South and the North provinces of Lebanon and living in a busy area increased the likelihood of developing asthma and rhinitis. Higher rates of asthma and eczema, however, was noted among students going to private schools (Odds Ratio (OR) = 1.6, 95% confidence interval (CI): 1.3-2.1 and OR = 1.3, 95% CI: 1.0-1.7, respectively). Passive smoking was significantly associated with asthma only (OR = 1.3, 95% CI: 1.1-1.7). In addition to the above, the odds of having any of the three outcomes increases to at least 2.4-fold when accompanied by another allergic disease. CONCLUSIONS: Allergic diseases are highly prevalent in Lebanon and are catching up with the rates of developed countries. Moreover, the role of each of the three diseases in the existence of the other two had the greatest impact on their prevalence.

Determinants of university students physical exercise: a study from Lebanon.

BACKGROUND: Studies to assess the patterns of physical exercise among University students in Lebanon are lacking. The current study looks at the prevalence of physical exercise among university students in Beirut and predictors of performing physical exercise. METHODS: In a cross-sectional study, a proportionate random sample of university students selected from five major universities were asked to complete a self-administered questionnaire related to physical exercise, demographic, scholastic, and health risk behavioral characteristics. Physical exercise was divided into: "No"" (< 0.5 h) and "Yes" (> 0.5 h) per week. Chi-square tests and binary regression were conducted to determine the predictors of performing physical exercise. RESULTS: Of 2,013 students, only 26.4% engaged in physical exercise. Predictors of performing physical exercise for males, were adoption of exercise as the method of weight control, while for females, they were living abroad, drinking excessive alcohol, and adopting exercise for weight control. CONCLUSION: The prevalence of physical exercise among Lebanese university students is low. Weight control remains the most important predictor of physical activity in males and females.
