PURPOSE: to compare the maternal factors, clinical aspects and perinatal results in placental abruption during two periods. METHODS: retrospective analysis of placental abruption cases that occurred from January 1, 1994 through December 31, 1997 (period 94-97), and from April 4, 2001 through March 3, 2005 (period 01-05), in singleton delivery with birthweight higher than 500 g and after 20 weeks of gestation. The following factors were analyzed: maternal age, previous obstetric history, prenatal care, premature rupture of membranes, obstetric and/or clinical intercurrent events, vaginal bleeding, uterine tonus, fetal anomaly, mode of delivery, hemoamnion and maternal complication (hysterectomy, uterine atony, disseminated intravascular coagulation, acute renal failure, and maternal death), and the perinatal results. RESULTS: the rate of placental abruption was 0.78% (60 cases) in the period 94-97 (n=7692 deliveries), and 0.59% (51 cases) in the period 01-05 (n=8644 deliveries), without significant difference. A significant difference was observed between the periods 94-97 and 01-05 regarding mean number of previous gestations (3.5±2.4 and 2.6±1.8, p=0.04), patients without prenatal care (13.3 and 2.0%, p=0.03) and maternal intercurrences (38.3 and 64.7%, p=0.01). No significant difference was observed related to vaginal bleeding, tonus abnormalities and perinatal results, between the periods, but a higher proportion of hemoamnion in 94-97 was found when compared to 01-05 (28.3 and 11.8%, p=0.03). CONCLUSIONS: in spite of obstetrical advances, maternal complications and perinatal results were similar in the analyzed periods. The severity and the unexpected results emphasize the importance of prevention and adequate control of associated factors, when this pathology is approached.

Purpose: to determine the feasibility of early ultrasonographic identification of fetal gender. Methods: a prospective study in a University Department of Obstetrics and Gynecology. A total of 592 women underwent ultrasonography at 11-14 weeks of gestation. Fetal gender was identified according to genital tubercle position (vertical or horizontal) at sagittal plane and confirmed at birth or by karyotype analysis. Results: the overall accuracy of correctly assigning fetal gender was 84%. The success of identification increased with gestational age, being 72%, 85% and 89% at 11, 12 and 13 weeks, respectively. The accuracy of correctly identifying fetal sex significantly changed with operator training, being 83.5% at the beginning and 93.6% at the end of the study. Conclusion: ultrasound determination of fetal gender is feasible, with good accuracy and may be of potential use to avoid invasive testing in family histories of X-linked disorders.
