RESUMEN
BACKGROUND: The aim of this study was to assess whether the presence of grade 3 placenta <36 weeks of pregnancy is associated with adverse perinatal outcomes. METHODS: Retrospective cohort study in which patients were separated into the following three groups: 1) grade 3 placenta <36 weeks, 2) grade 3 placenta >36 weeks, 3) no occurrence of grade 3 placenta throughout pregnancy. The χ2 and general linear model tests were used to compare adverse perinatal outcomes. Binary logistic regression model was used to estimate the odds ratio (OR) for adverse perinatal outcomes. Receiver operating characteristic (ROC) curve was used to determine the cut-off of the middle cerebral artery Pulsatility Index (MCA PI) in the detection of births <37 weeks in grade 3 placentas <36 weeks. RESULTS: Significant association was observed between grade 3 placenta <36 weeks and birth <37 weeks (P<0.001), birth weight <10th percentile (P=0.001), 5-min Apgar Score <7 (P=0.014), admission to neonatal intensive care unit (P<0.001), and fetal death (P=0.002). Grade 3 placenta <36 weeks was significant predictor for birth <37 weeks (OR: 2.6; 95% CI: 1.74-3.92), pre-eclampsia (OR: 1.8; 95% CI: 1.02-3.27), birth weight <10th percentile (OR: 2.1; 95% CI: 1.39-3.10), fetal death (OR: 5.6; 95% CI: 1.65-18.78), and composite perinatal outcomes (OR: 2.2; 95% CI: 1.51-3.17). The MCA PI showed an area under ROC curve of 0.641 (95% CI: 0.546-0.728) in the detection of births <37 weeks. CONCLUSIONS: Grade 3 placenta <36 weeks was associated with a higher prevalence of adverse perinatal outcomes.

Os aspectos clínicos, a epidemiologia, a etiopatologia e o diagnóstico da doença foram apresentados e debatidos pelos relatores do grupo de trabalho e médicos que participaram da reuniäo na qualidade de assistidos. As formas clínicas mais comuns no Brasil foram mencionadas, destacando-se o escofuloderma, a tuberculose cutânea indurativa de Bazin e a tuberculide papulóide necrótica. Criticou-se a ficha epidemiológica da Divisäo de Pneumologia Sanitária do Ministério da Saúde, em que a tuberculose cutânea näo aparece especificada, sendo registrada no item Outros. Uma revisäo dos principais estudos etiopatogênicos, o polimorfismo lesional e o grande acontecimento dos imunodeprimidos, principalmente os portadores da Aids, mereceram atençäo especial dos participantes. No diagnóstico foi ressaltada a grande contribuiçäo da técnica da PCR, que permite identificar a presença de raríssimas micobactérias, contribuindo para a precisäo diagnóstica.
