Background:The extensive use of computers as medium of teaching and learning in universities necessitates introspection into the extent of computer related health disorders among student population.Aim:This study was undertaken to assess the pattern of computer usage and related visual problems, among University students in Ajman, United Arab Emirates.Materials and Methods:A total of 500 Students studying in Gulf Medical University, Ajman and Ajman University of Science and Technology were recruited into this study. Demographic characteristics, pattern of usage of computers and associated visual symptoms were recorded in a validated self-administered questionnaire. Chi-square test was used to determine the significance of the observed differences between the variables. The level of statistical significance was at P < 0.05. The crude odds ratio (OR) was determined using simple binary logistic regression and adjusted OR was calculated using the multiple logistic regression.Results:The mean age of participants was 20.4 (3.2) years. The analysis of racial data reveals that 50% (236/471) students were from Middle East, 32% (151/471) from other parts of Asia, 11% (52/471) from Africa, 4% (19/471) from America and 3% (14/471) from Europe. The most common visual problems reported among computer users were headache - 53.3% (251/471), burning sensation in the eyes - 54.8% (258/471) and tired eyes - 48% (226/471). Female students were found to be at a higher risk. Nearly 72% of students reported frequent interruption of computer work. Headache caused interruption of work in 43.85% (110/168) of the students while tired eyes caused interruption of work in 43.5% (98/168) of the students. When the screen was viewed at distance more than 50 cm, the prevalence of headaches decreased by 38% (50-100 cm – OR: 0.62, 95% of the confidence interval [CI]: 0.42-0.92). Prevalence of tired eyes increased by 89% when screen filters were not used (OR: 1.894, 95% CI: 1.065-3.368).Conclusion:High prevalence of vision related problems was noted among university students. Sustained periods of close screen work without screen filters were found to be associated with occurrence of the symptoms and increased interruptions of work of the students. There is a need to increase the ergonomic awareness among students and corrective measures need to be implemented to reduce the impact of computer related vision problems.
The prevalence of the herbal medicines use is on the rise across the world, especially amongst pregnant women. The scenario in the Middle Eastern region was reviewed to explore the prevalence, usage pattern, motivation, and attitude towards use of herbal medicine by pregnant women. Literature published up to December 2012 showed the prevalence of herbal medicine use varied between 22.3-82.3%, implying a rising trend in the utilization of herbal medicine during pregnancy. The most common herbs used were peppermint, ginger, thyme, chamomile, sage, aniseed, fenugreek, and green tea. The most common reasons for use included the treatment of gastrointestinal disorders and cold and flu symptoms. The majority of women used these products during their first trimester, and did not reveal this information to their physician. Most women were advised by family and friends to use herbal medicines and believed they were more effective and had fewer side effects than modern medicine especially during pregnancy. In conclusion, the use of herbal medicine is prevalent among pregnant women in the Middle Eastern region and healthcare providers need to seek information pertaining to their use.
Background -The concept of psychosomatic medicine has gained popularity, with yoga racing ahead in the field. The present study was conducted to assess the effectiveness of yoga as an intervention in
Advances in technology have led to the replacement of animal based laboratories with computer based simulations. This pedagogical approach has the advantages of being less costly in terms of time and money, more accessibility for self study, repeatability of the intervention, ability to alter variables in isolation and needing less expert time for implementation. As medical educators we need to look beyond benefits of this intervention in terms of cost or time required for implementation and look closely at the educational impact of this change. This paper looks at the educational advantages of computer simulations on the basis of the principles of teaching and learning
