BACKGROUND Preterm premature rupture of membranes (PPROM) complicates 1% of all pregnancies and occurs in one third of all preterm deliveries. Midtrimester PPROM is often followed by spontaneous miscarriage and elective termination of ongoing pregnancies is offered in many countries. The aim of this retrospective descriptive cohort study was to investigate the natural history of midtrimester PP...
Purpose: The aim of this study was to investigate the mRNA expression level p16, CDK4, CDK6, Cyclin D, RB1, and E2F genes in preterm premature rupture membrane (PPROM) cases their roles etiopathogenesis PPROM. 
 Materials Methods: Twenty-one pregnancies with PPROM before 34th gestational weeks (study group) were compared twenty no complication, who gave birth after 37th gestational-week (c...
Objective The aim of this study was to assess which characteristics and results of vaginal examination are predictive for delivery within 7 days, in women with threatened preterm labor after initial treatment. Study Design A secondary analysis of a randomized controlled trial on maintenance nifedipine includes women who remained undelivered after threatened preterm labor for 48 hours. We develo...
OBJECTIVE Bacterial colonization of the fetal membranes and its role in pathogenesis of membrane rupture is poorly understood. Prior retrospective work revealed chorion layer thinning in preterm premature rupture of membranes (PPROM) subjects. Our objective was to prospectively examine fetal membrane chorion thinning and to correlate to bacterial presence in PPROM, preterm, and term subjects. ...
OBJECTIVES Preterm premature rupture of membranes (PPROM) is defined as a rupture of the amniotic membranes occurring before 37 weeks of gestation and before the onset of labor. Extreme PPROM occurs prior to 26 weeks gestation and contributes to an increased risk of prematurity, leading to maternal and fetal complications. This study aims to estimate the risk factors associated with various mat...
The problem Unfortunately there are too many examples in obstetrics of very important conditions for which there is no consensus of professional opinion about definition, diagnosis, risks, and above all, management. Preterm prelabour rupture of the membranes (PPROM) is such a case. The best, most widely used, and simplest definition of PPROM is membrane rupture occurring before the onset of reg...
BACKGROUND Preterm prelabour rupture of the fetal membranes (PPROM) precedes 30% of preterm births and is a risk factor for early onset neonatal sepsis. As PPROM is strongly associated with ascending vaginal infection, prophylactic antibiotics are widely used. The evolution of vaginal microbiota compositions associated with PPROM and the impact of antibiotics on bacterial compositions are unkno...
BACKGROUND Infection induced-inflammation and other risk factors for spontaneous preterm birth (PTB) and preterm premature rupture of membranes (pPROM) may cause a redox imbalance, increasing the release of free radicals and consuming antioxidant defenses. Oxidative stress, in turn, can initiate intracellular signaling cascades that increase the production of pro-inflammatory mediators. The obj...
BACKGROUND The clinical significance and management of preterm premature rupture of membranes (PPROM) remains a topic of a controversy. Although PROM is associated with a low rate of complications, PPROM may lead to significant neonatal and maternal morbidity. METHODS We performed a retrospective study of 714 women who presented to Jiangsu Province Hospital with third trimester PPROM or PROM ...
INTRODUCTION Our previous study revealed that anti-inflammatory cytokine gene polymorphisms increase the risk of spontaneous preterm delivery (PD) in a population of Polish women. Different genetic background of PD due to preterm premature rupture of membranes (pPROM) than PD without pPROM has been suggested. The aim of this study was to examine the relationship between the maternal carriage of...
