Effects of surface hydration state and application method on the bond strength of self-etching adhesives to cut enamel.

Purpose: To evaluate the effect of surface hydration state and application method on the microtensile bond strength of one-step self-etching adhesives systems to cut enamel.

Materials And Methods: One hundred ninety-five bovine teeth were used. The enamel on the buccal side was flattened with 600-grit SiC paper.

Neonatal screening for cystic fibrosis in São Paulo State, Brazil: a pilot study.

Cystic fibrosis is one of the most common autosomal recessive hereditary diseases in the Caucasian population, with an incidence of 1:2000 to 1:3500 liveborns. More than 1000 mutations have been described with the most common being F508del. It has a prevalence of 23-55% within the Brazilian population.

Cystic fibrosis and neonatal screening.

The clinical and diagnostic aspects of cystic fibrosis have been extensively reviewed, with an emphasis on neonatal screening. This systematic literature review involved a search for relevant contributions in the PubMed and SciELO databases. The first references to cystic fibrosis date to the Middle Ages.

Susceptibility profile of 200 bloodstream isolates of Candida spp. collected from Brazilian tertiary care hospitals.

We evaluated the antifungal susceptibility profile of 200 recent bloodstream isolates of Candida spp. sequentially obtained from patients admitted to five tertiary care hospitals in Brazil. Isolates were identified by classical methods and the antifungal susceptibility profile was determined by the NCCLS microbroth assay method.

Phenotypic and genotypic characterization of VanA Enterococcus isolated during the first nosocomial outbreak in Brazil.

We report the phenotypic and genotypic characterization of 50 VanA Enterococcus clinical isolates from infected patients and 97 isolates from colonized patients obtained during a nosocomial outbreak in a single hospital in São Paulo, Brazil during 1998. The identification of strains to the species level by conventional biochemical and phenotypic tests and by multiplex PCR assay had 100% agreement. Both E.
