Background. Formal education in primary care can reduce asthma exacerbations. However, there are few studies in hospitalized children, with none originating in Latin America. Methods. A prospective randomized study was designed to evaluate whether a full education with self-management plan (ESM) was more effective than an education without self-management plan (E) in reducing asthma hospitalization. Children (5 to 15 years of age) who were hospitalized for an asthma attack were divided in two groups. Children in the E group received general instructions based on a booklet. Those in the ESM group received the same booklet plus a self-management guide and a puzzle game that reinforces the lessons learned in the booklet. Patients were interviewed every 3 months, by telephone, for one year. Interviewers recording the number of hospitalizations, exacerbations, and emergency visits for asthma and oral steroid burst uses. Results. From 88 children who met the inclusion criteria, 77 (86%) completed one year of follow-up (41 from E and 36 from ESM group). Overall, after one year, the hospitalization decreased by 66% and the inhaled corticosteroids therapy increased from 36% to 79%. At the end of the study, there was no difference in exacerbations, emergency visits, oral steroid burst uses, or hospitalizations between the two groups. Conclusions. Asthma education with or without a self-management plan during asthma hospitalization were effective in reducing exacerbations, emergency visits, oral steroid burst uses, and future rehospitalizations. This evidence supports the importance of providing a complete asthma education plan in any patient who is admitted for asthma exacerbation.

ALA-PDT offers promise as an alternative treatment for moderately severe inflammatory acne that has a higher effectiveness than the combination of doxycycline and adapalene gel in reducing noninflammatory and total lesions at 6 weeks. There were significantly superior reductions at 12 weeks in the combination of PDT group followed by adapalene gel in total, inflammatory, and noninflammatory lesions.
