Abstract
OBJECTIVE The authors evaluated the effectiveness and safety of "neo-metoro" or 'mini-metoro" metreurynters plus oxytocin for labor induction and assessed differences in parturition outcomes, according to the metreurynter used at induction initiation. MATERIALS AND METHODS The authors retrospectively reviewed 146 consecutive women with live singleton pregnancies, and who underwent induction. Parturition outcomes were vaginal delivery achieved within the planned schedule (VDPS), vaginal delivery finally achieved (VDF), and induction-to-delivery interval (IDI). Women were divided into neo-metoro, mini-metoro, and without metreurynter groups based on metreurynter use at induction initiation. The authors examined the relationships of metreurynter groups with factors, parturition outcomes, and adverse events. In 113 women who underwent two-day induction, the authors calculated IDI and adjusted odds ratio (AOR) for achieving delivery per unit time. RESULTS VDPS rates were 65% in nulliparous and 81% in multiparous women. VDF rates were 78% in nulliparous and 96% in multiparous women. AORs for VDPS were 0.30 in nulliparous women and 0.18 in Bishop score (BS) 1-3 class. AORs for VDF were 0.04 in BS1-3 class and 0.14 in BS4-5 class. In 113 women undergoing two-day induction, AORs for achieving delivery per unit time were 0.45 in nulliparous women, 0.46 in obese women, and 0.48 in BS1-3 class. Neo-metoro use at induction initiation tended to reduce IDI. CONCLUSIONS Labor induction using these metreurynters plus oxytocin is safe and effective. The advantages of neo-metoro over mini-metoro use at induction initiation remain unclear; neo-metoro use at induction initiation may reduce IDI.

Abstract
AIM This study aimed to determine whether mechanical cervical dilatation with a laminaria tent in women with premature rupture of membranes (PROM) at term may influence the maternal/neonatal outcomes. METHODS We reviewed the medical records and histopathologic results of the placenta in 782 women with PROM at term. Of the 486 women seen prior to 2010 (group 1), 85 had Bishop scores of 5 or less and underwent insertion of laminaria tents (group A). In the 296 women admitted after 2010 (group 2), 27 had Bishop scores of 5 or less and underwent labor management without insertion of laminaria tents (group B). The patient characteristics, delivery course and neonatal outcomes were compared between the groups. RESULTS There were no significant differences in the maternal age, percentage of nulliparas, body mass index, gestational age at delivery or Bishop score between the groups. The Bishop score improved from 2.5 to 6.1 after laminaria tent insertion in group A. However, there were no significant intergroup differences in the frequency of use of labor-inducing agents or the time interval from PROM to delivery. The incidence of clinical/pathological chorioamnionitis was not higher in group A than in group B. No significant differences were found in the Apgar scores, umbilical artery pH or frequency of asphyxia neonatorum between the groups. Mechanical cervical dilatation by laminaria tent insertion neither increased the incidence of infection nor contributed to improvement of the perinatal prognosis. CONCLUSION Mechanical cervical dilatation does not provide any benefit for women with PROM at term.

Abstract
OBJECTIVE Preterm prelabor rupture of membranes is responsible for approximately one third of all preterm deliveries. The most common complications associated with this pregnancy pathology are microbial invasion of the amniotic cavity, intraamniotic inflammation, intraamniotic infection and histological chorioamnionitis. This article explains these complicatioss and their relation to the optimal management of preterm prelabor rupture of membranes. DESIGN Overview study. SETTING Department of Obstetrics and Gynecology, Charles University in Prague, Faculty of Medicine and University Hospital Hradec Kralove. METHODS To analyze current knowledge and our own experiences regarding inflammatory complications of preterm prelabor rupture of membranes. CONCLUSION Inflammatory complications of preterm prelabor rupture of membranes are associated with risk of development of early onset sepsis. Nevertheless, gestational age is a main confounder affecting neonatal morbidity and mortality.

Abstract
OBJECTIVE This study aims to treat patients with preterm premature rupture of the membranes (PPROM) and anhydramnion using continuous amnioinfusion through a subcutaneously implanted port system. METHODS An amniotic fluid replacement port system was implanted in seven patients with PPROM and anhydramnion starting at the 20th week of gestation (range, 14-26 weeks) for long-term amnioinfusion. Saline solutions (2 L/day; Jonosteril(®), Sterofundin(®), isotonic NaCl 0.9% solution, lactated Ringer's solution) and a hypotonic aqueous composition with reduced chloride content similar to the electrolyte concentration of human amniotic fluid were used for the continuous amnioinfusion. RESULTS The mean duration of the PPROM delivery interval continued for 49 days (range, 9-69 days), with 3 weeks of amnioinfusion via the port system (range, 4-49). The newborns showed no signs of lung hypoplasia. CONCLUSION Long-term lavage of the amniotic cavity via a subcutaneously implanted port system in patients with PPROM and anhydramnion may help prolong the pregnancy and avoid fetal lung hypoplasia. A hypotonic aqueous composition with reduced chloride content similar to human amniotic fluid can be safely used for amnioinfusion. Prospective randomized studies are ongoing.

Abstract
Over a 20-month period we identified several cases of neonatal pneumonia associated with prelabour rupture of membranes (PROM) at term. PROM complicates 8%-10% of all pregnancies, yet 60% of cases occur at term. Ascending infection is a contributing factor and the incidence of chorioamnionitis in these patients is relatively high, especially with prolonged membrane rupture. The signs and symptoms NICE recommends patients look out for are not always present as the majority of infections are subclinical, yet associated maternal and neonatal morbidity of chorioamnionitis is potentially devastating. A survey of maternity units in the West Midlands reveals significant variance in management of these cases. Given the lack of consensus and clear evidence on optimal management of PROM at term, we believe early detection of developing infections could be enhanced by using a combination of investigations (at presentation, 12 and 24 h), as well as current advice to self-monitor temperature and vaginal loss.

Abstract
OBJECTIVE Late-preterm (LPT) neonates account for over 70% of all preterm births in the US. Approximately 60% of LPT births are the result of non-spontaneous deliveries. The optimal timing of delivery for many obstetric conditions at LPT gestations is unclear, likely resulting in obstetric practice variation. The purpose of this study is to identify variation in the obstetrical management of LPT pregnancies. STUDY DESIGN We surveyed obstetrical providers in North Carolina identified from North Carolina Medical Board and North Carolina Obstetrical and Gynecological Society membership lists. Participants answered demographic questions and six multiple-choice vignettes on management of LPT pregnancies. RESULT We obtained 215/859 (29%) completed surveys which are as follows: 167 (78%) from obstetrics/gynecology, 27 (13%) from maternal-fetal medicine, and 21 (10%) from family medicine physicians. Overall, we found more agreement on respondents' management of chorioamnionitis (97% would proceed with delivery), mild pre-eclampsia (84% would delay delivery/expectantly manage) and fetal growth restriction (FGR) (80% would delay delivery/expectantly manage). We found less agreement on the management of severe preeclampsia (71% would proceed with delivery), premature preterm rupture of membranes (69% would proceed with delivery) and placenta previa (67% would delay delivery/expectantly manage). Management of LPT pregnancies complicated by preterm premature rupture of membranes, FGR and placenta previa vary by specialty. CONCLUSION Obstetrical providers report practice variation in the management of LPT pregnancies. Variation might be influenced by provider specialty. The absence of widespread agreement on best practice might be a source of modifiable LPT birth.

Abstract
OBJECTIVE The purpose of this study was to review systematically the efficacy of transabdominal amnioinfusion (TA) in early preterm premature rupture of membranes (PPROM). STUDY DESIGN We conducted a literature search of EMBASE, MEDLINE, and ClinicalTrials.gov databases and identified studies in which TA was used in cases of proven PPROM and oligohydramnios. Risk of bias was assessed for observational studies and randomized controlled trials. Primary outcomes were latency period and perinatal mortality rates. RESULTS Four observational studies (n = 147) and 3 randomized controlled trials (n = 165) were eligible. Pooled latency period was 14.4 (range, 8.2-20.6) and 11.41 (range -3.4 to 26.2) days longer in the TA group in the observational and the randomized controlled trials, respectively. Perinatal mortality rates were reduced among the treatment groups in both the observational studies (odds ratio, 0.12; 95% confidence interval, 0.02-0.61) and the randomized controlled trials (odds ratio, 0.33; 95% confidence interval, 0.10-1.12). CONCLUSION Serial TA for early PPROM may improve early PPROM-associated morbidity and mortality rates. Additional adequately powered randomized control trials are needed.

Abstract
OBJECTIVE To evaluate current knowledge about the management of preterm premature rupture of the membranes (PPROM). DESIGN Review article. SETTING Perinatological center, Department of Gynecology and Obstetrics, General Faculty Hospital and 1st Medical School of Charles University, Prague. METHODS AND RESULTS Expectant management in case of PPROM increases the incidence of infection/ inflammation but does not statistically increase mortality and serious morbidity of the infants. The incidence of infants morbidity corresponds with gestational age. The most serious complications occur in the lower gestational age. It is necessary to take an individual approach. The acute management increases the number of operative deliveries and respiratory distress syndrome (RDS) in the infants. The combination of RDS, extremely prematurity and hypoxia during the labour decreases the infants survival rate. CONCLUSIONS The prolongation of the latency period in pregnancies above 28th week does not deteriorate the neonatal mortality or morbidity.

Abstract
OBJECTIVES Premature rupture of the membranes (PROM) in pregnancy refers to rupture of membranes of the amniotic sac and chorion. The aim of the study was to review the literature and analyze the course of pregnancy (primipara) complicated by the premature rupture of the membranes, and consequent loss of amniotic fluid after 19 weeks of gestation. STUDY DESIGN A 27-year old primiparous patient was admitted to the Gynaecology and Obstetrics University Hospital in Poznań on 9 December 2010, due to suspected premature rupture of the membranes. On presentation, foetal development was at 19 weeks gestation. Standard clinical investigations included ultrasonography, amniotic fluid index measurements and laboratory blood tests. RESULTS Ultrasonography confirmed the size of the foetus to be normal for the gestational age. However, no amniotic fluid pockets were visible and the amniotic fluid index was 0 cm. The patient was hospitalized on multiple occasions and as a result a decision was made to end the pregnancy prematurely by means of a caesarean section at 32 weeks of gestation. Longer-term observation of the newborn indicated that one year following delivery, the development of the baby was normal, and thus far no neurological injuries or complications have been observed. CONCLUSION The pregnancy was ultimately successfully completed with the delivery of a healthy newborn at 32 weeks of gestation. A regime involving rigorous bed rest and antibiotic administration can positively extend the duration of pregnancies complicated by premature rupture of the membranes.

Abstract
Management of preterm premature rupture of membranes (PPROM) is a very challenging issue for the obstetricians. We report two cases of PPROM occurring in early gestation remote from term (both < 26 weeks) with exiguous amniotic fluid (amniotic fluid index of < or =2 cm) that were managed successfully by conservative treatment and resulted in a latency period of almost two months. This treatment option might be feasible in carefully selected patients following meticulous evaluation and warrants further research.

Abstract
BACKGROUND Preterm premature rupture of membranes (PPROM) is a leading cause of perinatal morbidity and mortality. Amnioinfusion aims to restore amniotic fluid volume by infusing a solution into the uterine cavity. OBJECTIVES The objective of this review was to assess the effects of amnioinfusion for PPROM on perinatal and maternal morbidity and mortality. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2011). SELECTION CRITERIA Randomised trials of amnioinfusion compared to no amnioinfusion in women with PPROM. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trials for inclusion. Two review authors independently assessed trial quality and extracted data. Data were checked for accuracy. MAIN RESULTS We included five trials but we only analysed data from four studies (with a total of 241 participants). One trial did not contribute any data to the review.Transcervical amnioinfusion improved fetal umbilical artery pH at delivery (mean difference 0.11; 95% confidence interval (CI) 0.08 to 0.14; one trial, 61 participants) and reduced persistent variable decelerations during labour (risk ratio (RR) 0.52; 95% CI 0.30 to 0.91; one trial, 86 participants).Transabdominal amnioinfusion was associated with a reduction in neonatal death (RR 0.30; 95% CI 0.14 to 0.66; two trials, 94 participants), neonatal sepsis (RR 0.26, 95% CI 0.11 to 0.61; one trial, 60 participants), pulmonary hypoplasia (RR 0.22; 95% CI 0.06 to 0.88; one trial, 34 participants) and puerperal sepsis (RR 0.20; 95% CI 0.05 to 0.84; one trial, 60 participants). Women in the amnioinfusion group were also less likely to deliver within seven days of membrane rupture (RR 0.18; 95% CI 0.05 to 0.70; one trial, 34 participants). These results should be treated with circumspection as the positive findings were mainly due to one trial with unclear allocation concealment. AUTHORS' CONCLUSIONS These results are encouraging but are limited by the sparse data and unclear methodological robustness, therefore further evidence is required before amnioinfusion for PPROM can be recommended for routine clinical practice.

Abstract
OBJECTIVE With the increased use of invasive fetal procedures, the number of patients facing postprocedure membrane rupture is increasing. We aimed to describe the use of platelets and fresh frozen plasma for sealing iatrogenic fetal membrane defects. PATIENTS AND METHODS We describe the mechanisms of action of the amniopatch procedure as well as published experience. RESULTS Amniopatch effectively sealed the fetal membranes in over two thirds of published cases (n=44). There is a risk of 17% of in utero fetal death, which may occur remotely from the procedure and is often unexplained. DISCUSSION AND CONCLUSION In case of early onset but persistent amniotic fluid leakage following an invasive fetal procedure, amniopatch may be offered.

Abstract
OBJECTIVE To outline possibility of successful treatment of spontaneous previable rupture of membranes in the second trimester of pregnancy. INTRODUCTION Spontaneous previable rupture of membranes (SPROM) in the second trimester of pregnancy is one of the most alarming problems in current obstetrics. Perinatal mortality is about 60 %, one third of which represents intrauterine fetal demise. Surviving neonates suffer from various complications. There are different clinical approaches regarding treatment of SPROM. MATERIAL AND METHODS We present a case of a 30 year old secundigravida with a history of SPROM at 19+1 weeks gestation. Ultrasonographic examination revealed anhydramnios. Genital cultures and laboratory studies ruled out infectious etiology of SPROM. Due to expected poor neonatal outcome, decision to attempt amniopatch as an experimental therapeutic alternative was made at 21+1 weeks gestation (two weeks after SPROM had occurred). Autologous concentrated platelets followed by autologous cryoprecipitate were administered into the amniotic cavity transabdominally under ultrasound guidance. After 3 days sonographic examination showed normal volume of amniotic fluid. On 22 postoperative day, patient notice some leaking of fluid vaginally. Fetal growth was appropriate, amniotic fluid volume was decreased, however, oligohydramnios never progressed to anhydramnios. Pregnancy ended with primary cesarean delivery at 33+1 weeks gestation. Live born male infant with 1750 g birth weight was delivered. Postnatal development was within normal limits. CONCLUSION Intraamniotic application of "amniopatch" may represent a possibly successful treatment of spontaneous previable rupture of membranes. This case reports the longest stop of the leaking of amniotic fluid and total prolongation of pregnancy with favorable perinatal outcome after "amniopatch" treatment of spontaneous previable rupture of membranes in the second trimester so far published in available literature.

Abstract
Spontaneous rupture of membranes before the onset of labor at term is commonly referred to as PROM (either premature or preterm rupture of membranes) and occurs in about 8% of term pregnancies. PROM is associated with an increased risk of infection. Many controversies exist regarding the optimal management of PROM, including the choice of induction or expectant management, use of digital vaginal exams, and routine administration of antibiotics. This article reviews the literature on PROM and illustrates some of the management issues encountered by presenting approaches used in three midwifery services.

Abstract
BACKGROUND/AIM Our aim was to evaluate the impact of in vitro cultured amnion cells, injected and/or seeded in different scaffolds, on in vivo fetal membrane repair. MATERIALS AND METHODS Amnion cells, isolated from allogeneic fetal membranes, were cultured on three different scaffolds for 14 to 21 days. In 33 mid-gestational rabbits, fetoscopic access sites were randomly allocated to four closure study groups: conventional collagen plug, as well as collagen plug, collagen foil, and fibrin glue as scaffolds for the cultured amnion cells. All membrane access sites were sealed with fibrin glue, and the myometrium closed with sutures. Fetal survival, amnion membrane integrity, and the presence of amniotic fluid were evaluated one week later. RESULTS Cultures showed good survival in the collagen scaffolds. The use of collagen plug as a scaffold for the in vitro cultured amnion cells improved the integrity of fetal membranes to 80%, better than that of any other study group. CONCLUSION Despite the need for additional studies, the present data suggest that amnion cells can be a practical and important source of cells for the engineering of constructs for sealing of the fetal membrane.

Abstract
OBJECTIVE To investigate safety and efficacy of dinoprostone suppositories (0.8 mm) used in cervical ripening and labor induction in women with term premature rupture of the membranes. METHODS One hundred women of term monocyesis with premature rupture of the membranes, head presentation, bishop score less than 6 (test group) and 180 women with intact fetal membranes (control group) were enrolled into this multicenter, prospective clinical study. The vaginal delivery system was inserted into the posterior fornix, and the patients were recumbent for 2 hours after insertion. The interval time from using dinoprostone suppositories to uterine contraction, to labor and delivery were recorded. The following index were also recorded and compared, including the mean inserted time of dinoprostone suppositories, fetal heart beat, meconium stained amniotic fluid, hyperstimulation of uterus and the other complications, mode of delivery, stage of labor, postpartum hemorrhage, status of neonates. RESULTS Three cases in test group and 23 cases in control group weren't in labor within 24 hours. The rate of labor within 24 hours in test group was significant higher than that in control group (97.0% vs. 87.2%, P < 0.01). It was observed that 73 cases undergoing vaginal deliveries (75.3%, 73/97) and 24 cases undergoing cesarean section deliveries (24.7%, 24/97)in test group and 107 cases undergoing vaginal delivery (68.2%, 107/157) and 50 cases undergoing cesarean section delivery (31.8%, 50/157) in control group, when compared the rate of vaginal or cesarean section deliveries between two group, it didn't reach statistical difference (P > 0.05). It had no significant difference in the interval time from using dinoprostone suppositories to labor starting and the mean inserted time and the total labor time between two groups (P > 0.05). The incidence of uterine tachysystole was 11.3% (11/97) in test group and 19.1% (30/157) in control group (P > 0.05), which did not reach statistical difference (P > 0.05). There wasn't neonatal asphyxia in both groups. CONCLUSION It was safe and efficient to use dinoprostone suppositories for cervical ripening and induction of term pregnancy with premature rupture of the membranes, however, monitoring should be intensified.

Abstract
BACKGROUND Preterm prelabour rupture of membranes (PPROM) is associated with increased risk of maternal and neonatal morbidity and mortality. Women with PPROM have been predominantly managed in hospital. It is possible that selected women could be managed at home after a period of observation. The safety, cost and women's views about home management have not been established. OBJECTIVES To assess the safety, cost and women's views about planned home versus hospital care for women with PPROM. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (January 2010) and the reference lists of all the identified articles. SELECTION CRITERIA Randomised and quasi-randomised trials comparing planned home versus hospital management for women with PPROM before 37 weeks' gestation. DATA COLLECTION AND ANALYSIS Two review authors independently assessed clinical trials for eligibility for inclusion, risk of bias, and carried out data extraction. MAIN RESULTS We included two trials (116 women) comparing planned home versus hospital management for PPROM. Overall, the number of included women in each trial was too small to allow adequate assessment of pre-specified outcomes. Investigators used strict inclusion criteria and in both studies relatively few of the women presenting with PPROM were eligible for inclusion. Women were monitored for 48 to 72 hours before randomisation. Perinatal mortality was reported in one trial and there was insufficient evidence to determine whether it differed between the two groups (risk ratio (RR) 1.93, 95% confidence interval (CI) 0.19 to 20.05). There was no evidence of differences between groups for serious neonatal morbidity, chorioamnionitis, gestational age at delivery, birthweight and admission to neonatal intensive care.There was no information on serious maternal morbidity or mortality. There was some evidence that women managed in hospital were more likely to be delivered by caesarean section (RR (random-effects) 0.28, 95% CI 0.07 to 1.15). However, results should be interpreted cautiously as there is a moderate heterogeneity for this outcome (I(2) = 35%). Mothers randomised to care at home spent approximately 10 fewer days as inpatients (mean difference -9.60, 95% CI -14.59 to -4.61) and were more satisfied with their care. Furthermore, home care was associated with reduced costs. AUTHORS' CONCLUSIONS The review included two relatively small studies that did not have sufficient statistical power to detect meaningful differences between groups. Future large and adequately powered randomised controlled trials are required to measure differences between groups for relevant pre-specified outcomes. Special attention should be given to the assessment of maternal satisfaction with care and cost analysis as they will have social and economic implications in both developed and developing countries.

Abstract
OBJECTIVE To evaluate the effect of transabdominal amnioinfusion on prolongation of pregnancy, and maternal and neonatal outcomes in preterm premature rupture of membranes (pPROM). METHODS We conducted a prospective randomized controlled study of women with pPROM during singleton live pregnancy-between 26 and 33+6weeks-whose amniotic fluid index (AFI) was less than the 5th percentile. The study group underwent transabdominal amnioinfusion at admission and then weekly if their AFI fell below the 5th percentile again. The control group received expectant management. RESULTS The difference in the mean interval from pPROM to delivery between the groups was not statistically significant. Neonatal and maternal outcomes were significantly improved in the study group compared with the control group (fetal distress [10% vs 37%]; early neonatal sepsis [17% vs 63%]; neonatal mortality [17% vs 63%]; spontaneous delivery [83% vs 53%]; and postpartum sepsis [7% vs 33%]). CONCLUSION Transabdominal amnioinfusion reduced fetal distress, early neonatal sepsis, and neonatal mortality. In the study group, more participants delivered spontaneously and there were fewer cases of postpartum sepsis, although the pPROM-delivery interval was not increased.

Abstract
BACKGROUND Preterm premature rupture of membranes is responsible for one third of all preterm births and is associated with significant maternal, foetal and neonatal risks. The objectives were to compare the foeto-maternal outcome in patient with and without preterm premature rupture of membranes. METHOD This prospective comparative study was conducted in Gynae-C Unit of Ayub Teaching Hospital from Sep 2005 to Mar 2006. Total 170 cases were recruited in the study out of which 85 had Preterm Premature Rupture of Membranes (PPROM), and 85 had preterm labour without PROM. Patients' data were recorded on a performa. Maternal outcome was measured on the basis of presence of fever and mode of delivery. Foetal outcome was measured on the basis of weight of the baby, and presence of infection (fever), APGAR score and neonatal death. Analysis was performed using SPSS-10. RESULTS The primary data arranged in groups was divided into PPROM and no-PPROM groups. The PPROM was found to be frequent in younger age group between 15-25 years while no-PPROM was common among the age group between 26-35 years (p = 0.002). Lower socioeconomic class and history of previous one or more preterm delivery was significantly associated with PPROM (p = 0.001). Maternal fever was also significant in the PPROM group (p = 0.01). Low birth weight was statistically significant in the PPROM group. Majority of the babies born to mother were either extremely low birth weight or low birth weight, i.e., between 1-25 kg (p = 0.005). Low APGAR score at the time of delivery (p = 0.01) and foetal infection (p = 0.002) between the PROM and no-PPROM group was found to be statistically significant Neo-natal deaths was also higher in the PPROM group as compared to no PPROM group (11 verses 2) (p = 0.009). CONCLUSION In our study premature rupture of membrane had increased neonatal morbidity and mortality as compared to preterm birth. Strategies should be developed for its prevention.

Abstract
OBJECTIVE Obesity has been associated with chronic inflammation. We hypothesized that body mass index may be inversely related to latency and directly related to infectious complications after preterm premature rupture of membranes. STUDY DESIGN This secondary analysis of a randomized trial of antibiotics for preterm premature rupture of membranes had information available for 562 subjects. We analyzed the association between body mass index and latency, the occurrence of chorioamnionitis, endometritis, and maternal infectious morbidity after controlling for gestational age at rupture and treatment group. Survival analysis, regression, and test of proportions were used as appropriate. RESULTS When evaluated as a categorical or continuous variable, body mass index did not reveal any significant associations. Latency to delivery was affected by gestational age at rupture of membrane and antibiotic therapy but not by body mass index group. CONCLUSION Body mass index was not associated with latency or the occurrence of maternal infectious complications during conservative management of premature rupture of membranes before 32 weeks' gestation.
