Abstract: the aim of this paper was to investigate the experience of dental caries in a population of young adults from salvador - ba, and to associate the prevalence of caries with the utilization of topical fluoride. a cross-sectional study was carried out with a sample of 493 persons aged 12-20 years, from salvador - ba. data were obtained from interviews and clinical examinations and they were analyzed through backward logistic regression. the dmft was 4.44 (sd 3.71), and, for subjects aging 12-13 years, it was 2.72 (sd 2.75). a hundred and forty adolescents reported that they had participated in oral health programs (30%), and the majority felt that they were unable to maintain their own oral health. topical fluoride was not a significant factor in the decrease of the prevalence of caries among these young adults (rp = 0.9). there was a decline in dental caries in this group. however, it is necessary to review the surgical-restorative model of dental practice in order to achieve better results in the promotion of oral health.

Abstract: Os objetivos deste trabalho foram: descrever a experiência de cárie dental em adolescentes de 12 a 20 anos de Salvador - BA e testar a associa o entre a severidade da cárie e o uso do flúor tópico na forma de gel ou bochechos. Realizou-se um estudo transversal e análise de regress o logística n o condicional, pelo método "backward", com uma amostra de 493 adolescentes escolares do Distrito Sanitário Barra-Rio Vermelho. As variáveis de desenho foram obtidas a partir de questionário semi-estruturado e exame bucal. O CPOD correspondeu a 4,44 (DP 3,71), sendo de 2,72 (DP 2,75) aos 12-13 anos. Cento e quarenta e quatro adolescentes participaram de a es de promo o de saúde bucal (30%) e a maioria declarou-se pouco apta a manter a própria saúde oral. O flúor tópico n o se mostrou como um fator de prote o significativo na redu o da cárie dental nesta popula o (RP = 0,9). Houve redu o dos índices de cárie dental nos adolescentes do Distrito, embora exista a necessidade de reformula o do modelo cirúrgico-restaurador de aten o à saúde bucal, para maior controle da cárie dental e melhor efetividade dos métodos de promo o e prote o à saúde bucal.

Abstract: the present study is aimed to describe the mortality in the county of salvador in 1980, as distributed over different areas, by using overall mortality coefficients, proportional mortality ratios, proportional mortality curves and guedes & guedes indicators. death certificates from residents in salvador during 1980, available in the health state office of bahia, were used as data sources. they were grouped according to census tracts as defined by conder (company for the development of salvador) as well as socio-economic indicators gathered from several sources in different public offices. correlation analyses between mortality measures and selected socio-economic indicators were used. a marked variation of indicators among different city sectors was found, even considering the use of an indicator with low discriminant power as the overall mortality coefficient. the indexes of moraes and swaroop-uemura and guedes & guedes scoring system pointed out evident inequalities in the distribution of deaths among different sectors of salvador. high levels of correlation were found between proportional mortality ratio and income, water supply, and population density, reinforcing the idea that at the basis of such mal-distribution is the economic structure as a generator of inequalities.
A concep??o de "espa?o" na investiga??o epidemiológica

Abstract: epidemiology's conceptual and methodological shortcomings have placed constraints on the study of health phenomena related to human communities, thus posing a challenge to the field. this paper presents some basic principles resulting from the observation of the field of geography in defining its object - space - and the application of this object to medicine and epidemiology. such principles state the pertinence of a conceptual and methodological strategy focusing on an approach to geographic space as expressing the population's living conditions. application of this concept to epidemiological studies is still limited, although such proposals have already been developed in other areas of knowledge. ecological studies, whose unit of analysis is the group, and the ecological model, based on the idea of an inter-relationship of factors, if improved, could become a promising alternative in this direction. the authors emphasize that researchers should have wholeness as their scientific reference in order to guarantee the non-separation of the complex interactive processes determining health phenomena in the population.

Abstract: As atuais fragilidades conceituais e metodológicas da epidemiologia s o fatores que têm restringido o estudo dos fen menos de saúde das coletividades humanas. Neste artigo alguns princípios básicos s o apresentados como resultado da observa o do percurso da geografia na defini o do seu objeto - o espa o - e da sua aplica o na medicina e na epidemiologia. Esses princípios fundamentam a pertinência da estratégia conceitual e metodológica que tem como perspectiva a abordagem do espa o geográfico-social, já que este é entendido como express o das condi es de vida da popula o. A aplica o desse conceito na prática da investiga o epidemiológica ainda é limitada, embora outras áreas do conhecimento já tenham desenvolvido propostas de supera o. Os estudos de agregados, cuja unidade de análise é o grupo, mais freqüentemente os agregados espaciais, e o modelo ecológico que se baseia na idéia de inter-rela o de fatores, se aperfei oados, podem vir a ser uma alternativa promissora nesta dire o. Destaca-se que a totalidade deve ser a referência científica, visando garantir o n o afastamento dos complexos processos interativos determinantes dos fen menos de saúde na popula o.

Abstract: an ecological study was performed to identify patterns in the spatial distribution of neonatal mortality and risk areas as well as associated factors in salvador, bahia state, brazil, 2000-2006. a thematic map was constructed, and techniques were used for formal assessment of spatial dependence. no spatial and spatial regression models were used to assess possible relationships between selected factors and spatial distribution of neonatal mortality. spatial autocorrelation was observed in neonatal mortality (i = 0.17; p = 0.0100), so its distribution was non-random. the analysis showed a spatial pattern in which the highest risk (> 9.0/1,000 live births) was concentrated in the downtown areas and peripheral neighborhoods with the highest concentration of low-income families, and this was associated with the target risk factors. the proportion of low birth weight newborns was the only variable that was significantly associated with neonatal mortality. living conditions may have contributed to the uneven spatial distribution of neonatal mortality in this city.

Abstract: an ecological study was carried out using information zones as units of analysis in order to assess the evolution of socio-spatial inequalities in mortality due to external causes and homicides in salvador, bahia state, brazil, in 2000 and 2006. the brazilian institute of geography and statistics (instituto brasileiro de geografia e estatística - ibge) and the city health department (secretaria municipal de saúde) provided the data sources, and causes of death were reviewed and reclassified based on reports from the institute of legal medicine (instituto médico legal). the information zones were classified into four social strata according to income and schooling. the ratio between mortality rates (inequality ratio) was calculated and confirmed a rise of 98.5% in the homicide rate. in 2000, the risk of death due to external causes and murders in the stratum with the worst living conditions was respectively 1.40 and 1.94 times greater than in the reference stratum. in 2006 these figures were 2.02 and 2.24. the authors discuss the implications for inter-sectoral public policies, based on evidence from the study's findings.

Abstract: an ecological study was carried out with the aim of analyzing the evolution of inequalities in mortality in salvador, bahia state, brazil, between 1991 and 2006. the city was divided into four social strata from 95 geographic information zones. the variables used for social stratification were education level and income of heads of households. crude and age-standardized mortality rates, age specific mortality rates, proportional infant mortality and the proportional mortality ratio, were calculated for each zone and social strata. data was obtained from death certificates and the populational census. although differences between strata were smaller in 2000 than in 1991, they persist and are still high, ranging from 28.7% to 65.5%. the differences between information zones were as much as 575%. the authors discuss the shortcomings of information systems, recommending that health indicators should be estimated by social classes and pointing out the limits and possibilities of the methodology used here.

Abstract: an ecological study was conducted to describe the urban spatial distribution of mortality attributable to tuberculosis in salvador, bahia, brazil in 1991, 1994, and 1997. the unit of analysis was the health district (hd). the hd with the highest standardized rates was subúrbio ferroviário in 1991, 1994, and 1997, with 15.7, 10.6, and 10.6/100.000 inhabitants, respectively. inequalities in mortality between hds were high. the year 1997 showed the lowest standardized rates. the proportional mortality ratios for tuberculosis when compared with total deaths from infectious diseases were 20.7%, 18.2%, and 16.9% for 1991, 1994, and 1997 respectively. the highest rates were observed in the age group over 65 years. the authors argue the possibilities of using the results for the implementation of equitable local health policies and health surveillance measures, since the methodology identified both the hd with the highest risk and the most heavily affected age groups.
Dengue and dengue hemorrhagic fever epidemics in Brazil: what research is needed based on trends, surveillance, and control experiences?

Abstract: dengue epidemics account annually for several million cases and deaths worldwide. the high endemic level of dengue fever and its hemorrhagic form correlates to extensive domiciliary infestation by aedes aegypti and multiple viral serotype human infection. this study analyzed serial case reports registered in brazil since 1981, describing incidence evolutionary patterns and spatial distribution. epidemic waves followed the introduction of every serotype (den 1 to 3), and reduction in susceptible individuals possibly accounted for decreasing case frequency. an incremental expansion of affected areas and increasing occurrence of dengue fever and its hemorrhagic form with high case fatality were noted in recent years. in contrast, efforts based solely on chemical vector control have been insufficient. moreover, some evidence demonstrates that educational measures do not permanently modify population habits. thus, as long as a vaccine is not available, further dengue control depends on potential results from basic interdisciplinary research and intervention evaluation studies, integrating environmental changes, community participation and education, epidemiological and virological surveillance, and strategic technological innovations aimed to stop transmission.
