Study Design: A retrospective cohort study was performed on women undergoing IOL. Early ROM was defined as ROM at a modified Bishop score less than 5, cervical dilation less than 4 cm, or cervical effacement less than 80%. The rate of clinical chorioamnionitis was compared between women with early and late ROM. Results: The rate of clinical chorioamnionitis was 8.6% (24/279). ROM at an effacement of less than 80% was associated with a rate of clinical chorioamnionitis of 15.4% (12/78) compared to 6.0% (12/201) at an effacement of equal to or greater than 80%, p = 0.017. The rate of cesarean delivery was higher for patients with early ROM by any definition: 32% compared to 17.5% by modified Bishop score (p = 0.031), 32.4% versus 18.2% by cervical dilation (p = 0.049), and 33.3% versus 14.9% by cervical effacement (p = 0.001). Conclusions: In patients undergoing IOL, early ROM may be associated with an increased rate of clinical chorioamnionitis when performed at a cervical effacement of less than 80% and an increased rate of cesarean delivery.展开更多

Maternal colonization by GBS can cause amniotic infection and thus fetal infection, sometimes causing fetal death. This infection generally occurs in association with premature rupture of membranes. We present here an infrequent case of GBS chorioamnionitis in full-term gestation with intact amniotic membranes. The curiosity of the case lies in the integrity of the amniotic membranes, the asymptomatic clinical presentation, and the adverse result (term fetal death).展开更多

Methods: A total of 80 pregnant women with premature rupture of membranes were selected as PROM group and 80 normal pregnant women as control group. The PROM group was subgrouped into HCA group (n=45) and non HCA group (n=35) according to the presence or absence of HCA. Matrix metalloproteinases (MMP-8, MMP-9) and cytokines (IL-8, IL-10, TNF-α) in pregnant women were compared. Results: The level of IL-8, TNF-αwere (420.45±110.26) ng/L, (413.53±125.19) ng/L in the PROM group, which were significantly higher than those in the control group;the levels of IL-10 were(332.07±48.12) ng/L in the PROM groups, which were significantly lower than the control group. The levels of IL-8 and TNF-α in PROM combined with HCA group were significantly higher than those in non-HCA group, the levels of IL-10 were significantly lower than those in non-HCA group. The level of MMP-8, MMP-9 were (11.02±2.48) ng/mL, (648.42±73.35) ng/L in the PROM group, which were significantly higher than the control group. The levels of MMP-8, MMP-9 in PROM combined with HCA were significantly higher than those in non-HCA group with the difference was statistically significant. Conclusion: When premature rupture of membranes and chorioamniositis occurring, pregnant women were accompanied by the level changes of cytokines and matrix metalloproteinases, so timely monitoring of these indicators can offer basis for the early diagnosis the premature rupture of membranes and chorioamnionitis, which will help to reduce morbidity and mortality of the perinatal pregnant women and newborns with important clinical value.展开更多
