Objective: analyze the prevalence of recurrent wheezing and its risk factors. Method: systematic literature review, guided by the research question “what is the prevalence of recurrent wheezing and its risk factors?”. The search was performed in the databases MedLine and LILACS, in April and May 2013. The inclusion criteria were: scientific study, fully available, published between 2002 and 2013, with free access. Results: wheezing presents a higher prevalence in developing countries, possibly due to poor socioeconomic conditions. Among its risk factors, we find heredity, mother’s education level, attendance of day nursery, smoking during pregnancy, breastfeeding for < 3 months, animals in the household of children, among others. Conclusion: in Latin America, the prevalence of wheezing shows to be high and the use of non-standardized instruments hampers its treatment.

To investigate the relationship between Body Mass Index (BMI) and asthma symptoms in adolescents between 13 and 14 years, to estimate the prevalence of obesity in this age group. This is a crosssectional study with a quantitative approach which was rated the Body Mass Index (BMI) and applied the Questionnaire International Study of asthma and Allergies in Childhood (ISAAC) phase III (asthma module) to determine the prevalence of asthma and related symptoms, as well as its severity in 85teenagers. According to the assessment of asthma in relation to BMI, it was found that there were significant findings, as well as in males and females. However, the association between BMI and asthma symptoms, there was a significant association to present as disturbed sleep and impaired speech. Conclusions: In this sample the prevalence of obesity was low, this fact may have contributed to the nonsignificant findings betweenasthma and BMI.

The intense valuation of an esthetic pleasant smile guided the dentistry to bleached tooth due the popularity of whitening treatments. The consequence of it is an increasing interest in searching the effect of peroxides in hard dental tissues. The aim of this work was to analyze qualitatively in vitro the human enamel after three different bleaching treatments: Opalescence PF 10%, White Class 7.5% and Opalescence Xtra Boost 38%, correlating the structural changes in the surface of the enamel with its respective pH. A total of 40 sound human pre-molars were randomly divided into four groups of 10 elements, which had been immersed in artificial saliva during all the experiment. Bleaching protocols followed the recommendations of the respective manufacturers. Each bleached sample and control group were submitted to a scanning electronic microscopy analysis and compared with one another. Bleaching agents used in this experiment had modified the morphologic aspect of the surface of the dental enamel; however, it did not have correlation between the degrees of severity of the alterations and pH. There is a correlation between hydrogen peroxide concentration and changes in the enamel, where G4 showed more severe alterations, followed for G3 and G2.
