- Isolation and Genotyping of Rubella Virus From a Case of Congenital Infection in Brazil(2011) ANDRADE, J. Q.; FIGUEIREDO, C. A.; OLIVEIRA, M. I.; CARVALHO, M. H. B.; SCHULTZ, R.; ZUGAIB, M.The incidence of CRS and CRI has decreased markedly worldwide with the implementation of efficient vaccination programs. We report a congenital rubella case with fetal death occurred at 29th week of gestation. RV was confirmed in placenta. The results of phylogenetic analysis showed that the RVs/Sao-Paulo01.- BRA/08.CRI belongs to the genotype 2B of RV. J. Med. Virol. 83:2048-2050, 2011. (C) 2011 Wiley-Liss, Inc.
- Ultrasound detection rate of single umbilical artery in the first trimester of pregnancy(2011) LAMBERTY, Clarissa O.; CARVALHO, Mario Henrique Burlacchini de; MIGUELEZ, Javier; LIAO, Adolfo Wenjaw; ZUGAIB, MarceloObjective To determine accuracy of first trimester detection of single umbilical artery (SUA). Methods The number of vessels in the umbilical cord was examined in a prospective cohort of 779 singleton, low-risk, unselected pregnancies, in the first (11-13 weeks) and second (17-24 weeks) trimesters, using both power and color Doppler and after delivery, by placental histopathologic exam. Concordance between first and second trimester findings to postnatal diagnoses was compared by calculating kappa coefficients. Results There was medium concordance between the findings in the first trimester and the postnatal diagnoses (kappa = 0.52) and high concordance (kappa = 0.89) for the second trimester scan. Sensitivity, specificity, positive and negative predictive values for the findings in the first trimester were 57.1, 98.9, 50.0 and 99.2% and for the second trimester were 86.6, 99.9, 92.9 and 99.7%. Conclusion Sensitivity and positive predictive value of first trimester scan to identify an isolated SUA in a prospective unselected population was poor. Diagnosis of isolated SUA as well as a definitive judgment about the presence of associated anomalies would still require a scan in the second trimester.
