Histologic chorioamnionitis increases major perinatal morbidity through its association with preterm birth and is independently associated with neonatal death. In the presence of histologic chorioamnionitis, antenatal steroids significantly decreased the incidence of RDS, intraventricular hemorrhage and periventricular leukomalacia, major brain lesions, and neonatal mortality, without increasing neonatal sepsis.

Placenta accreta is a complication that is rising in incidence. The reported experience of methotrexate treatment in the conservative management of placenta accreta is scant. Three cases of placenta accreta managed with methotrexate are presented. Case 1: A woman had an antenatal diagnosis of placenta percreta. A successful manual placental removal occurred on post-cesarean day 16. Case 2: A woman had retention of a placenta accreta after a term vaginal delivery. Successful dilation and curettage were performed on postpartum day 37. Case 3: A woman had an antenatal diagnosis of placenta previa-percreta with bladder invasion. A simple hysterectomy was performed on post-cesarean day 46. Conservative management and methotrexate treatment resulted in uterine preservation in two of our three patients; however, this treatment did not prevent significant delayed hemorrhage. In view of the rapid resolution of vascular invasion of the bladder, methotrexate may have an important role in the management of placenta percreta with bladder invasion. The utility of methotrexate treatment with the conservative management of placenta accreta requires further evaluation.

Women with preterm labor and intact membranes that delivered within 7 days had higher AF concentrations of pro-inflammatory cytokines than those who delivered after 7 days of the amniocentesis regardless of the AF culture results.
