OBJETIVO: Estimar a prevalência de bronquite aguda, rinite e sinusite em crianças e adolescentes e identificar fatores associados. MÉTODOS: Estudo transversal, de base populacional. Foi realizado inquérito domiciliar com 1.185 crianças e adolescentes de São Paulo, SP, de 2008 a 2009. Os participantes foram selecionados a partir de amostragem probabilística, estratificada por sexo e idade e por conglomerados em dois estágios. Para análise ajustada foi realizada regressão múltipla de Poisson. RESULTADOS: Dos entrevistados, 7,3% referiram bronquite aguda, 22,6% rinite e 15,3% sinusite. Após análise ajustada, associaram-se à bronquite aguda auto-referida: idade de zero a quatro anos (RP = 17,86; IC95%: 3,65;90,91), cinco a nove anos (RP = 37,04; IC95%: 8,13;166,67), dez a 14 anos (RP = 20,83; IC95%: 4,93;90,91), referir ter alergia (RP = 3,12; IC95%: 1,70;5,73), cor da pele preta/parda (RP = 2,29; IC95%: 1,21;4,35) e morar em domicílio com um a três cômodos (RP = 1,85; IC95%: 1,17;2,94); à rinite auto-referida: idade dez a 14 anos (RP = 2,77; IC95%: 1,60;4,78), 15 a 19 anos (RP = 2,58; IC95%: 1,52;4,39), referir ter alergia (RP = 4,32; IC95%: 2,79;6,70), referir ter asma (RP = 2,30; IC95%: 1,30;4,10) e morar em apartamento (RP = 1,70; IC95%: 1,06;2,73); à sinusite auto-referida: idade cinco a nove anos (RP = 2,44; IC95%: 1,09;5,43), dez a 14 anos (RP = 2,99; IC95%: 1,36;6,58), 15 a 19 anos (RP = 3,62; IC95%: 1,68;7,81), referir ter alergia (RP = 2,23; IC95%: 1,41;3,52) e apresentar obesidade (RP = 4,42; IC95%: 1,56;12,50). CONCLUSÕES: As doenças respiratórias foram mais prevalentes em grupos populacionais com características definidas, como grupo etário, doenças auto-referidas, tipo de moradia e obesidade.

Introduction: sexually transmitted diseases (DST) can represent an important impact on teenager’s health due its consequences. Objective: to identify the perception and knowledge of teenagers about DST, its transmission forms and contraception. Methods: it was made a cross-sectional study type investigation, with 136 teenager students from a Technical Education Public Institution in a middle-sized city. It was used a tested instrument, self answered, with opened and closed questions about theme and sociodemographic data. The same data were stored and analyzed by Program Epi Info version 3.5.1. Results: 97,1% affirmed to know male condoms, 89,0% oral contraceptives, 87,5% female condoms, 74,3% postcoital contraceptives, 47,8% natural family planning methods, 41,9% hormonal injection, 33,1% intrauterine devices, 31,6% coitus interruptus and 1,5% other contraceptive methods. According with them, the information was gave principally on high school (46,1%), by friends or partners (20,3%), doctor (10,9%), television (10,2%). In relation to DST, 98,5% affirmed that diseases can be transmitted during coitus. The aids (91,2%) and herpes (72,8%) were the most cited diseases. Just 31,6% of teenagers affirmed that run the risk to acquire some DST, and 88,4% of them, due no use of condoms, 30,2% due their partner make relation with other people, 18% due have many sexual partners and 9,3% due other causes. Conclusion: even teenagers knowing many contraceptive methods and sexually transmitted diseases, the teenagers have not prevented theirselves yet. It’s necessary that the high school reinforce the use of contraceptive methods, because the school is an important source of educative information on health area.

The association of Helicobacter pylori with different gastric diseases has been continuously discussed in the literature, whereas the last 20 years a large body of publications was intended to characterize the ecological niches and habitats of this pathogen being the mouth a possible habitat for that rod. The present study aimed to discuss the occurrence of this organism as part of the supplemental or transient microbiota of the mouth. Thus, an extensive review of literature covering the period 1990-2014 was carried out with different databases, yielding 5024 articles discussing transmission and occurrence of H. pylori, in English or Portuguese. Articles were selected according to the inclusion and exclusion criteria and data were tabulated and analyzed. Despite the significant heterogeneity of the literature, it was found this microaerophilic has a worldwide distribution, even in the mouth, which behaves as a reservoir for gastric reinfection. The role of oral hygiene and periodontal disease in the distribution of this microorganism remains unclear, but most studies support the hypothesis that oral biofilms and inflammation of periodontium may facilitate the installation of this pathogen in the mouth. Studies suggest that this microorganism could collaborate as a predisposing factor for oral cancer.

Periodontal disease has been increasingly associated as a supporting factor, and even a precursor to some systemic diseases. Just aim of this paper was to analyze by reviewing the literature, the possible mechanisms involved in the etiopathogenesis of periodontal disease that are common to the current systemic diseases such as obesity, atherosclerosis, diabetes and rheumatoid arthritis. The articles were analyzed with in the publication period of the years 2006 to 2011 and were surveyed in the databases PubMed, LILACS and SciELO. Of a total of 907 articles found by searching the indices and their associations, were selected by inclusion criteria 93 articles. For the preparation of this literature review, only 24 articles were selected because they are based on inflammatory mechanisms, metabolic and infectious, where the considerations for the strongest associations in the literature. This literature review reinforces the association of periodontal disease with systemic diseases analyzed due to presence of inflammatory and immunological mechanisms and similar synergism betwen the two diseases, but some hypotheses still need further clarification. The professional should stick to recent discoveries associations to promote periodontal treatment in preventing the development of systemic diseases, as well as in maintaining the systemic health of patients already suffering from chronic systemic diseases.
