RESUMO
AIM: Determine the risk indicators of caries lesion activity in a child sample from Porto Alegre, Brazil. MATERIALS AND METHODS: Study design: cross-sectional study included 97 individuals aged between 3 and 12-years who sought treatment at the Paediatric Clinic at the Dental Teaching Hospital at the Federal University of Rio Grande do Sul, between 2017 and 2018. Questionnaires recorded sociodemographic data, frequency of sugar intake, and toothbrushing frequency. Clinical examination included the visible plaque index, gingival blood index, and caries lesion activity. RESULTS: s The mean of surfaces with active caries lesions was 9.81 (IC 95% = 8.47-11.15). Children who presented a frequency of sugar intake of twice/day (PR = 1.62, IC 95% = 1.30-2.03), three times/day (PR = 1.68, IC 95% = 1.37-2.08), and four or more times/day (PR = 1.59, IC 95% = 1.26-2.01), were likely to have active lesions. Ages between 8 and 12-years were associated with a lower probability of active carious lesions (PR = 0.77, IC 95% = 0.66-088). STATISTICS: Poisson regression analysis was used to estimate the child's relative risk of developing new active caries lesions. CONCLUSIONS: The monitoring of sugar intake should be considered a strong instrument for the strategies of control of dental caries in children.

OBJECTIVE: It is to describe outbreaks of salmonellosis reported from July 1993 through June 1997 in the Northwest region of S. Paulo State, Brazil, one of the areas where several foodborne outbreaks of salmonellosis have been recently detected. METHOD: Data of 19 epidemiological investigations were analysed; 87 stool specimens and 38 food samples (including 12 of shell eggs) were processed for microbiological analysis. Salmonella strains were identified by serotyping, phagetyping and antimicrobial susceptibility testing. RESULTS: There were 906 ill persons including 295 hospitalized patients. Phage type 4 (PT 4) Salmonella Enteritidis strains were isolated from 80.5% of stool samples, from all food samples and from 41.7% of eggs. Of the outbreaks, 95.7% were associated with the consumption of food containing raw or undercooked eggs. All strains were susceptible to the 13 antimicrobials, except the strains from the nosocomial outbreak. CONCLUSIONS: The results obtained show the need for the implementation of control measures regarding egg and storage, as well as for guidance to the public as to the risks involved in the consumption of inadequately prepared eggs.
