ABSTRACT
BACKGROUND: Leukotriene receptor antagonists have been used to prevent virus-induced asthma exacerbations in autumn. Its efficacy, however, might differ with age and sex. OBJECTIVE: This study aimed to investigate whether pranlukast added to usual asthma therapy in Japanese children during autumn, season associated with the peak of asthma, reduces asthma exacerbations. It was also evaluated the effect of age and sex on pranlukast's efficacy. METHODS: A total of 121 asthmatic children aged 1 to 14 years were randomly assigned to receive regular pranlukast or not according to sex, and were divided in 2 age groups, 1–5 years and 6–14 years. The primary outcome was total asthma score calculated during 8 weeks by using a sticker calendar related to the days in which a child experienced a worsening of asthma symptoms. This open study lasted 60 days from September 15 to November 14, 2007. RESULTS: Significant differences in pranlukast efficacy were observed between sex and age groups. Boys aged 1 to 5 years had the lower total asthma score at 8 weeks (p = 0.002), and experienced fewer cold episodes (p = 0.007). There were no significant differences between pranlukast and control group in total asthma score at 8 weeks (p = 0.35), and in the days in which a child experienced a worsening of asthma symptoms (p = 0.67). CONCLUSION: There was a substantial benefit of adding pranlukast to usual therapy in asthmatic children, especially in boys aged 1 to 5 years, during autumn season.

The preparation for influenza pandemic has become very important. However, no standardized educational package against pandemics has been established to date. We developed a simulation–based education drill for Japanese medical students based on the package developed by U.S. medical school. The drill was adapted to 201 medical students, and was evaluated by self–administered questionnaires.<br>1)More than 90% of the students indicated that the use of this drill is appropriate to experience a simulated pandemic situation, and to learn skills and attitudes such as teamwork and communication.<br>2)Up to 65% of the students answered they learned a "very clear image" for the "Importance of working as a team with other professionals".<br>3)The results suggest that this simulation–based education drill make the students aware not only of the need for the preparation for pandemic but also the importance of team–based approach.
