We investigated Ureaplasma urealyticum genital tract colonization rates in an Australian population to determine whether colonization was associated with adverse pregnancy outcome. Women attending an antenatal clinic were evaluated for lower genital tract colonization at their first antenatal visit (162 women) and at 28 weeks' gestation (120 women). Placentas from 92 women were cultured. U. urealyticum was the predominant isolate from the lower (57.4%) and upper (17.4%) genital tract in this population of pregnant women. U. urealyticum was a persistent colonizer during mid-trimester of pregnancy (in 88% of women colonized) whereas M. hominis, G. vaginalis, and Group B streptococcus were present as transient flora of the lower genital tract. Lower genital tract colonization during pregnancy was not directly associated with adverse pregnancy outcome. However preterm delivery in afebrile, asymptomatic women, could possibly be associated with chorioamnionitis (4 of 16 preterm births). Screening of women with a history of preterm birth may prevent upper genital tract infections and preterm delivery.

Four hundred-microgram misoprostol PV can be recommended for the medical management of miscarriage on an outpatient basis.

Controversy reigns over the role of Ureaplasma urealyticum in determining pregnancy outcome. U. urealyticum infection of the chorioamnion is strongly associated with chorioamnionitis (1-3), premature birth (2-4), and perinatal morbidity (4-6). We present 4 cases of U. urealyticum chorioamnionitis and associated morbidity and mortality.

The Caesarean section rate in consecutive years was decreased from 20.5% to 11.1% of total public deliveries (p < 0.0001). On retrospective analysis the emergency Caesarean section rate decreased from 10.9% to 6.0% (p < 0.0001) and elective Caesarean section rate from 9.6% to 5.1% (p < 0.0001) in consecutive years. Interventions which have accounted for the decrease were 3-fold. Firstly, vaginal birth after Caesarean delivery was encouraged, secondly, the active management of labour and thirdly, extensive, regular peer review were introduced as unit policy. The decrease in the Caesarean section rate was not achieved at the expense of the fetus as judged by perinatal mortality rates and 5-minute Apgar scores of less than 7.
