[Sensitivity and specificity of epidemiological criteria for the case definition of congenital syphilis in a retrospective cohort in BrazilSensibilidad y especificidad de los criterios epidemiológicos para la definición de los casos de sífilis congénita en una cohorte retrospectiva en Brasil].

Objective: To assess the sensitivity and specificity of the modified criteria for case definition of congenital syphilis implemented in 2017, which excluded treatment of the sexual partner as a necessary condition for adequate maternal treatment.

Methods: This retrospective cohort study involved epidemiological monitoring of 503 children born in 2018 and living in Porto Alegre, Brazil: 412, including miscarriages and stillbirths, had been reported as congenital syphilis cases; 91, who had been exposed to syphilis during pregnancy, were no longer considered cases after partner treatment was excluded as a criterion for adequate maternal treatment. The study involved observation of treatment at birth, laboratory follow-up with non-treponemal tests up to age 18 months or treponemal tests after age 18 months, and symptom-based screening for cohort closure.

Human leptospirosis in Porto Alegre, Rio Grande do Sul, Brazil, 2007-2013: characterization of confirmed cases and spatial distribution.

Objective: to characterize confirmed human leptospirosis cases resident in Porto Alegre, Rio Grande do Sul, Brazil, between 2007 and 2013, and their spatial distribution.

Methods: this was a descriptive study of cases registered on the Notifiable Diseases Information System; we investigated neighborhoods and areas in the catchment area of Health Units (US) with highest case occurrence, using spatial analysis as per the Kernel technique.

Results: 228 cases were confirmed in the period, with cumulative incidence of 2.

Factors associated with not having Pap Smears in São Leopoldo, Rio Grande do Sul, Brazil, 2015: a cross-sectional population-based study.

Methods: this was a cross-sectional study with women aged 20 to 69 years living in São Leopoldo, RS, Brazil, in 2015; prevalence ratios (PR) were calculated using Poisson regression.

Results: among 919 women, prevalence of delayed testing was 17.

[HIV and syphilis coinfection in pregnancy and vertical HIV transmission: a study based on epidemiological surveillance data].

Objective: To estimate the rate of HIV and syphilis coinfection among pregnant women living in Porto Alegre, Brazil, as well as the association of coinfection with vertical HIV transmission and socioeconomic variables.

Method: This analytical retrospective cross-sectional study employed data from the regular epidemiological surveillance system for the period from 2010 to 2013. Data were obtained regarding pregnant women with HIV and exposed children, syphilis in pregnancy, and congenital syphilis.

[The distribution of tuberculosis in Porto Alegre: analysis of the magnitude and tuberculosis-HIV coinfection].

Objective: Analyzing the geographical distribution of the tuberculosis (TB), its incidence and prevalence and TB-HIV coinfection in the districts of Porto Alegre from 2007 to 2011.

Method: An ecological, descriptive study of time series that used descriptive and geoprocessing techniques.

Results: In total, were recorded 3,369 incident cases and 3,998 prevalent cases of pulmonary TB.

The Porto Alegre paradox: social determinants and tuberculosis incidence.

Introduction: The incidence of tuberculosis (TB) is strongly associated with social and economic factors.

One would expect that the incidence of tuberculosis in such a place were low.

Surveillance of mother-to-child HIV transmission: socioeconomic and health care coverage indicators.

Objective: To identify clustering areas of infants exposed to HIV during pregnancy and their association with indicators of primary care coverage and socioeconomic condition.

Methods: Ecological study where the unit of analysis was primary care coverage areas in the city of Porto Alegre, Southern Brazil, in 2003. Geographical Information System and spatial analysis tools were used to describe indicators of primary care coverage areas and socioeconomic condition, and estimate the prevalence of liveborn infants exposed to HIV during pregnancy and delivery.

[Estimate of HIV prevalence in pregnant women by means of spatial analysis in Southern Brazil].

Spatial analysis techniques were used to estimate the interurban differential HIV prevalence among pregnant women in the city of Porto Alegre, Southern Brazil. The estimates were produced through the spatial smoothing of residence pinpoints with live newborns and HIV infected pregnant women for the year of 2003. The overlay of high prevalence areas in city slums was identified.
