RESUMEN
BACKGROUND: In twin pregnancies, the cord prolapse of either fetus during the pre-viable period leads to fetal death but can also cause an intrauterine infection, leading to death or prematu-re birth of the remaining fetus. However, there are no validated protocols to prolong the gestational period or decrease the morbidity and mortality of the remaining fetus. CASE PRESENTATION: The present cases were PPROM and cord prolapse very early during the second trimester (around 17 weeks in the first case and 19 weeks in the second case). The first fetus was evacuated, and cervical cerclage was performed at 23 and 20 weeks in the two cases, respectively. After maintaining the pregnancy, the second baby was born around 27 and 39 weeks in the first and second cases, respectively. The delivery interval between the first and second fetuses was 46 days in the first case and 126 days in the second case. CONCLUSION: If cord prolapse is identified at a pre-viable time in twin fetuses, evacuation and cerclage should be performed as soon as possible after the cord prolapse to reduce intrauterine infection and increase the survival chances of the remaining fetus.

OBJECTIVE: To assess differences in the perioperative complication rate between patients with placenta accreta spectrum (PAS) with and without complicating factors. METHODS: This retrospective cohort study included subjects who underwent cesarean hysterectomy with histology-proven PAS between 23 0/7 and 42 0/7 weeks gestational age (GA) from 1 July 2008 to 11 April 2017. Perioperative outcomes were compared between those with uncomplicated PAS and "complicated PAS," defined as PAS subjects who experienced ≥2 bleeding episodes, preterm premature rupture of membranes (PPROM), or premature contractions requiring tocolysis. RESULTS: Overall, 26 complicated PAS and 27 uncomplicated PAS cases were compared; no difference in the rate of perioperative complications was identified. An increased proportion of complicated PAS cases required blood product transfusion before delivery: 2 (40%), 3 (27.3%), and 2 patients (20%) for those with PPROM, preterm contractions, and ≥2 bleeding episodes respectively, compared to patients with uncomplicated PAS, having no transfusions (p = .001). Time of delivery was earlier for patients with complicated compared to uncomplicated PAS (median GA 30.9 [Q1 = 27.9; Q3 = 31.9] and 34.9 [Q1 = 32.1; Q3 = 35.7], p < .001). Median birthweights were lower (p < .0144) and maternal length of stay longer (p < .0012) for complicated PAS. CONCLUSION: Patients with complicated PAS were not at higher risk for perioperative complications but were associated with earlier delivery, required more antenatal blood transfusions, and had a longer LOS.

OBJECTIVE: Spina bifida (SB) is a congenital birth defect defined as a failure of the neural tube formation during the embryonic development phase. Fetoscopic repair of SB is a novel treatment technique that allows to close spinal defect early and prevent potential neurological and psychomotor complications. CASE REPORT: We present a case report of a 32-year-old-multigravida whose fetus was diagnosed with lumbosacral myelomeningocele at 23rd week. Fetoscopic closure of MMC was performed at 26 weeks. At 32 weeks, due to premature amniorrhexis and placental abruption, an emergency C-section was performed. Newborn's psychomotor development was within normal limits. CONCLUSION: Although intrauterine treatment has an increased risk of premature labor, placental abruption, prenatal closure is associated with improved postnatal psychomotor development. Prenatal surgery decreases the risk of Arnold-Chiari II malformation development and walking disability. Fetoscopic closure of SB is becoming a choice for treatment with beneficial outcomes for mother and fetus.

BACKGROUND: Amniotic band syndrome is a rare phenomenon, but it can result in serious complications. We report herein our experience of amniotic band syndrome in a monochorionic diamniotic twin pregnancy where rupture of the dividing membrane occurred early in the second trimester. CASE PRESENTATION: A 29-year-old nulliparous woman was referred to us for management of her monochorionic diamniotic twin pregnancy at 10 weeks of gestation. When we were unable to identify a dividing membrane at 15 weeks of gestation using two-dimensional ultrasonography, we used three-dimensional ultrasonography to confirm its absence. Both modalities showed that the left arm of baby B was swollen and attached to a membranous structure originating from the placenta at 18 weeks of gestation. Tangled umbilical cords were noted on magnetic resonance imaging at 18 weeks of gestation. Emergency cesarean delivery was performed at 30 weeks of gestation because of the nonreassuring fetal status of baby A. The left arm of baby B had a constrictive ring with a skin defect. Both neonates had an uncomplicated postnatal course and were discharged around 2 months after delivery. CONCLUSIONS: Attention should be paid to the potential for amniotic band syndrome if rupture of the dividing membrane between twins is noted during early gestation.

Preterm prelabor rupture of membranes (PPROM) is the main cause of preterm delivery, resulting in increased perinatal morbidity and mortality. Several techniques have been studied for the healing of ruptured membranes, with some success. Before new techniques using tissue/organ engineering are applied in clinical practice, these techniques must be validated in clinical trials. To address this issue, the objective of this study was to summarize the current literature on interventions to seal or heal the amniotic membranes after PPROM. An electronic search was conducted using the keywords "fetal membranes," "premature rupture," "amnion," "tissue engineering," "fibrin tissue adhesive," "regenerative medicine," "tissue adhesive," "wound healing," and "fetoscopy" through the MEDLINE, Embase, and Cochrane CENTRAL databases, with the limitation of English-language studies. Through a review of the identified studies, it was found that spontaneous healing of the fetal membrane has not been successful. Several efforts have been made to seal membranes before or after rupture using different methods, including amniopatches, collagen, tissue patches, fibrin sealant, mussel-mimetic sealant, engineered cell matrix, and immunological supplements. However, most studies have been conducted in ex vivo or in vivo settings, so the safety and applicability of these techniques to spontaneous rupture of membranes in clinical settings have not been sufficiently tested. Overall, the current evidence is limited regarding the safety and effectiveness of interventions against PPROM.

OBJECTIVE: The aim of this study was to estimate if preterm premature rupture of membranes in women with cerclage is due to the cerclage itself or rather the underlying risk factors for preterm birth in this population. STUDY DESIGN: This was a retrospective cohort study of singleton pregnancies who underwent Shirodkar cerclage by a single maternal-fetal medicine practice between 2005 and 2019. The control group was an equal number of randomly selected women with a singleton gestation who had a prior preterm birth and were treated with 17-OH-progesterone but no cerclage. Patients with major uterine anomalies or fetal anomalies were excluded. The primary outcome was preterm premature rupture of membranes prior to 34 weeks. Chi-square and logistic regression were used. RESULTS: A total of 350 women with cerclage (154 [44%] history-indicated, 137 [39%] ultrasound-indicated, and 59 [17%] exam-indicated) and 350 controls were included. Preterm premature rupture of membranes prior to 34 weeks did not differ between the groups (8.9% in cerclage vs. 6.0% in controls, p = 0.149, adjusted odds ratio 0.62, 95% confidence interval: 0.24-1.64) nor between the different cerclage indications (9.1% of history-indicated, 7.3% of ultrasound-indicated, and 11.9% of exam-indicated, p = 0.582). This study had 80% power with an α error of 0.05 to detect an increase in preterm premature rupture of membranes prior to 34 weeks from 6.0% in the control group to 12.0% in the cerclage group. CONCLUSION: Cerclage does not increase the risk of preterm premature rupture of membranes prior to 34 weeks compared with other women at increased risk of preterm birth. The observed association between cerclage and preterm premature rupture of membranes is likely due to underlying risk factors and not the cerclage itself. The risk of preterm premature rupture of membranes prior to 34 weeks in women with cerclage is 10% or less and does not appear to differ based on cerclage indication. KEY POINTS: · Cerclage does not increase the risk of PPROM.. · Risk of PPROM with cerclage is approximately 10%.. · Risk does not appear to vary by indication..

Preterm prelabor rupture of membranes (PPROM) is the most frequent complication of fetal surgery. Strategies to seal the membrane defect created by fetoscopy aiming to reduce the occurrence of PPROM have been attempted with little success. The objective of this study was to evaluate the ex-vivo mechanical sealing properties and toxicity of four different bioadhesives integrated in semi-rigid patches for fetal membranes. We performed and ex-vivo study using term human fetal membranes to compare the four integrated patches composed of silicone or silicone-polyurethane combined with dopaminated-hyaluronic acid or hydroxypropyl methylcellulose (HPMC). For mechanical sealing properties, membranes were mounted in a multiaxial inflation device with saline, perforated and sealed with the 4 combinations. We measured bursting pressure and maximum pressure free of leakage (n = 8). For toxicity, an organ culture of membranes sealed with the patches was used to measure pyknotic index (PI) and lactate dehydrogenase (LDH) concentration (n = 5). All bioadhesives achieved appropriate bursting pressures, but only HPMC forms achieved high maximum pressures free of leakage. Concerning toxicity, bioadhesives showed low PI and LDH levels, suggesting no cell toxicity. We conclude that a semi-rigid patch coated with HPMC achieved ex-vivo sealing of iatrogenic defects in fetal membranes with no signs of cell toxicity. These results warrant further research addressing long-term adhesiveness and feasibility as a sealing system for fetoscopy.

PURPOSE: To compare pregnancy outcomes in women with pPROM and a cervical cerclage in whom the cerclage was removed within 24 h and those in whom the cerclage was retained in situ. METHODS: A two-center retrospective cohort study of women with a singleton gestation with pPROM at < 340/7 weeks of gestation in the presence of cervical cerclage (January 1, 2012-July 30, 2016). Maternal and perinatal outcomes were compared between women in whom cerclage was removed within 24 h from pPROM and those in whom cerclage was retained until the onset of delivery. The primary outcome was time from pPROM to delivery. RESULTS: Seventy women met inclusion criteria. Cerclage was left in situ in 47 (67.1%) and removed in 23 (32.9%) women. Women in the cerclage retention group had a higher pPROM-to-delivery interval (7.0 ± 7.2 vs. 6.0 ± 10.9 days, p = 0.03), and were more likely to have a latency period > 48 h (87.2% vs. 65.2%, p = 0.03; aOR 3.9, 95% CI 3.1-4.9) or > 7 days (29.8% vs. 8.7%, p = 0.04; aOR 7.0, 95% CI 2.5-19.6) compared with women in whom cerclage was removed. Furthermore, chorioamnionitis rate was lower in the cerclage retention group compared to cerclage removal group (aOR 0.7, 95% CI 0.5-1.0). There were no differences between the groups in early neonatal sepsis, severe brain injury, or composite neonatal outcome. CONCLUSION: In women with pPROM and cervical cerclage, retention of cerclage may be associated with a longer latency period, and a lower chorioamnionitis rate, without an associated increase in the risk of neonatal infectious morbidity. Presentation information: The abstract of this study was presented as a poster at the 38th SMFM (Society of Maternal and Fetal Medicine) annual meeting, February 2018, Dallas, Texas, USA.

For women with a history of cervical insufficiency, treatment with transvaginal (TV) or abdominal (TA) cerclage is often recommended; however management of pregnancy complications necessitating uterine evacuation in the second trimester are challenging. We present a patient at 17â¯weeks 3â¯day gestation with preterm premature rupture of membranes, and chorioamnionitis with an abdominal cerclage in situ. She desired uterine evacuation via dilation and evacuation. This case report reviews the clinical considerations for uterine evacuation in the second trimester in patients with an abdominal cerclage in situ and discusses options for cervical preparation prior to dilation and evacuation for this unique patient population.

BACKGROUND: Preterm premature rupture of membranes (PPROM) is associated with high neonatal morbidity and mortality. However, the influences of cesarean section (CS) on neonatal outcomes in preterm pregnancies complicated with PPROM are not well elucidated. The aim of this study was to investigate the influence of delivery modes on neonatal outcomes among pregnant women with PPROM. METHODS: A retrospective cross-sectional study was conducted in 39 public hospitals in 14 cities in the mainland of China from January 1st, 2011 to December 31st, 2011. A total of 2756 singleton pregnancies complicated with PPROM were included. Adverse neonatal outcomes including early neonatal death, birth asphyxia, respiratory distress syndrome (RDS), pneumonia, infection, birth trauma, and 5-min/10-min Apgar scores were obtained from the hospital records. Binary variables and ordinal variables were respectively calculated by binary logistic regressions and ordinal regression. Numerical variables were compared by multiple linear regressions. RESULTS: In total, 2756 newborns were involved in the analysis. Among them, 1166 newborns (42.31%) were delivered by CS and 1590 newborns belonged to vaginal delivery (VD) group. The CS proportion of PPROM obviously increased with the increase of gestational age (χâ=â5.014, Pâ=â0.025). Compared with CS group, VD was associated with a higher risk of total newborns mortality (odds ratio [OR], 2.38; 95% confidence interval [CI], 1.102-5.118; Pâ=â0.027), and a lower level of pneumonia (OR, 0.32; 95% CI, 0.126-0.811; Pâ=â0.016). However, after multivariable adjustment and stratification for gestational age, only pneumonia was significantly related with CS in 28 to 34 weeks group (OR, 0.34; 95% CI, 0.120-0.940; Pâ=â0.038). There were no differences regarding to other adverse outcomes in the two groups, including neonatal mortality, birth asphyxia, Apgar scores, RDS, pneumonia, and sepsis. CONCLUSIONS: The proportion of CS of pregnant women with PPROM was very high in China. The mode of delivery does not affect neonatal outcomes of pregnancies complicated with PPROM.

Postpartum hemorrhage is a leading cause of maternal and fetal mortality. Although rare, peripartum splenic rupture (PSR) is a lethal cause of bleeding due to variable presentation and delayed diagnosis. A 22-year-old gravida 2, para 0, abortus 1 (G2P0A1) woman presented for premature rupture of membranes and was diagnosed with Influenza A and chorioamnionitis. She underwent emergent cesarean delivery under general anesthesia. Postoperatively, her condition worsened despite treatment for presumed sepsis. She was taken to the operating room for an exploratory laparotomy, and a splenectomy was performed for splenic rupture. We discuss management, risk factors, challenges, and importance of prompt treatment of PSR.

BACKGROUND To study the clinical effective of emergency cervical cerclage (ECC) in pregnant women who have cervical insufficiency with prolapsed membranes. MATERIAL AND METHODS This study was devised as a retrospective cohort in a single medical center, in which we collected clinical data from patient records. Inclusion criteria were: physical examination indicated ECC was performed at 15 to 25 gestational weeks at the Sixth Medical Center of the PLA General Hospital, and singleton pregnancy. The collected clinical data included: duration of pregnancy at delivery, interval between ECC and delivery, neonatal weight, neonatal mortality, neonatal morbidity, and Neonatal Intensive Care Unit (NICU) admission. RESULTS We included 50 women with singleton pregnancies. No surgical complications occurred in any patients. The gestational age at cerclage was 21.3±2.2 weeks. No patients had membrane damage due to surgery. No surgical complications were reported. Five (10%) patients underwent chorioamnionitis. The time interval between ECC and delivery was 11.2±7.1 weeks. The mean gestational age at delivery was 34.1 weeks. The rate of vaginal delivery was 96%. Ten patients had pregnancy lasting longer than 36 weeks. The mean neonate delivery weight was 2510.7 g. Twenty neonates were admitted to the Neonatal Intensive Care Unit (NICU), and the mean NICU stay was 21 days. CONCLUSIONS ECC has good perinatal results. Our results provide clinical evidence for the efficacy and risks of ECC.

BACKGROUND: Herlyn-Werner-Wunderlich syndrome (HWWS) is an uncommon congenital anomaly of the female urogenital tract, characterised by uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis. We reported the difficult pregnancy course complicated by an extremely rare and unique case of this syndrome associated with ectrodactyly, a clinical combination never described in literature. CASE PRESENTATION: A 28- year-old nulliparous woman previously diagnosed for HWWS associated with ectrodactyly of the right foot and with a history of abdominal left hemi-hysterectomy, ipsilateral salpingectomy, vaginal reconstruction when she was an adolescent. She suffered from threats of abortion in the first trimester, recurrent urinary tract infections during all pregnancy. At 33 weeks + 5 days of gestational age, she was hospitalized for premature rupture of the membranes and uterine contractions and a caesarean section was performed because of breech presentation. Postpartum period was complicated by a pelvic abscess resolved with parental antibiotic therapies. CONCLUSIONS: Our literature review shows an unusual aspect in our case: HWWS is not classically associated with skeletal anomalies. Moreover, the most frequent urogenital side affected is the right, not left side as in this woman. Preterm spontaneous rupture of membranes and fetal abnormal presentation represent frequent complications and probably post-caesarean infections are related to pregnancies in the context of this syndrome.

BACKGROUND: The increase in number of cesarean section (CS) operations has resulted in an increase in cases of isthmocele development. The objective of this study is to determine the risk factors for isthmocele development after CS. METHODS: Isthmocele measurements were taken for 404 women with a history of at least one low transverse CS. The following potential risk factors were investigated: patient's age at CS, cause of CS, weeks of gestation at CS, premature rupture of membrane (PROM), phase of labor, type suture (single/double layer), operation time, uterine flexion (anteversion/retroversion), and blood transfusion during operation. A transvaginal ultrasound was carried out to examine the isthmocele in the uterus after CS, including the shape of the isthmocele, residual myometrial thickness, depth and width of isthmocele, cervical thickness, location of the isthmocele, and clinical characteristics. RESULTS: In our study population, the isthmocele had a prevalence of 73.8%. Most isthmocele had a triangular (65.4%) or semicircular shape (10.4%). The presence of an isthmocele was significantly associated with repeat CS, premature rupture of membrane (PROM), short operation time, and extent of cervix dilatation at CS. The risk of isthmocele was low in women who had placenta previa totalis (PPT), twin, a long operation time, or a transfusion during the operation. CONCLUSIONS: In our study, isthmocele development was significantly associated with repeat CS, PROM, a short operation time, and the extent of cervix dilatation at CS. Therefore, PROM prevention and a more careful uterine closure are needed to reduce the risk of developing an isthmocele after CS.

OBJECTIVE: To describe the outcomes of patients transferred to King Edward Memorial Hospital (KEMH) with signs of labour at preterm gestations. DESIGN: A retrospective observational study of the 69 cases transferred to KEMH during 2015. SETTING: Patient transfers from all locations across Western Australia (WA) to the sole tertiary perinatal centre in Perth. PARTICIPANTS: Pregnant women within WA with threatened or actual preterm labour (PTL) or preterm prelabour rupture of membranes (PPROM) between 23 and 32 weeks gestation. MAIN OUTCOME MEASURES: The occurrence of delivery during the admission and time-to-delivery as well as length of admission and association between clinical factors and time-to-delivery. RESULTS: The percentage of the study population delivered during the admission following transfer was 72.5%. Eighty-six per cent of those who delivered did so within 72 hours of transfer. The median time from transfer to delivery was 1 day. Sixty-three per cent of those who did not deliver during the admission progressed to 36 weeks gestation. Patients transferred with PPROM were less likely to deliver during the admission compared to those with uterine activity (50% versus 19.6%, P = 0.007) and nulliparas were more likely to deliver (93.5% versus 55.3%, P < 0.001). CONCLUSION: The majority of women transferred with signs of PTL progress to delivery during the same admission with the highest risk of delivery being the first 72 hours following transfer. If the pregnancy is ongoing at 72 hours, there is a reasonable chance of progression to late preterm gestation supporting the return of woman to their place of origin for antenatal care following discharge.

OBJECTIVE: The purpose of this study is to investigate the factors associated with successful amniopatch treatment in patients with iatrogenic preterm premature rupture of membranes (iPPROM) or spontaneous PPROM (sPPROM) before 23 weeks' gestation. MATERIALS AND METHODS: This cohort study included 28 women who received amniopatch treatment due to iPPROM or sPPROM at 15-23 weeks' gestation. Patients' clinical characteristics before performing the amniopatch, factors associated with the procedure, pregnancy and neonatal outcomes were compared between the iPPROM and sPPROM groups, and also between the successful and failed groups. RESULTS: The amniopatch was successful in 6 of 28 patients (21.4%) with a success rate of 36.4% (4/11) and 11.8% (2/17) in the iPPROM group and sPPROM group (P = 0.174), respectively. The success group had a longer PPROM-to-delivery interval, fewer cases of clinical chorioamnionitis, larger birth weight, and lower neonatal intensive care unit admission rate than the failed group. The success rate of amniopatch procedure was proportional to maximal vertical pocket prior to procedure, which showed statistically significant association (adjusted odds ratio: 3.62, 95% confidence interval: 1.16-11.31, P = 0.027). CONCLUSION: The amniopatch treatment success rate was higher in the iPPROM group than the sPPROM group, but was not statistically significant. The neonatal outcome was more favorable when the amniopatch was successful. However, the only predictive factor associated with successful amniopatch was a larger amniotic fluid volume before the procedure.

OBJECTIVE: Difficulties often encountered during intubation in extremely low birth-weight (ELBW) neonates requiring resuscitation at birth because of the smaller airway and the pressure from the limited number of attempts before hemodynamic instability occurs. CASE REPORT: We evaluated two pregnant women at 26 weeks of gestation with premature rupture of membranes and evidence of chorioamnionitis and applied the concept of ex utero intrapartum treatment, which involved delaying cord clamping (DCC) after establishing a secured airway with adequate ventilation during cesarean delivery. The resuscitative procedure was smooth and all three neonates had favorable outcomes at one month of age. CONCLUSION: When cesarean delivery is indicated in ELBW infants and intubation after birth is anticipated, DCC after establishing a secured airway may help maintain neonatal cardiovascular stability and allow physicians to resolve the technical difficulties of intubation.

BACKGROUND: Most very low birth weight (VLBW, birth weight <1500 g) infants receive empiric antibiotics for risk of early-onset sepsis (EOS). The objective of this study was to determine the characteristics of VLBW infants with culture-confirmed EOS at a single center during 25 years and to identify opportunities for antibiotic stewardship. METHODS: Retrospective cohort study includes VLBW infants admitted from 1990 to 2015. EOS was defined as isolation of a pathogen in blood or cerebrospinal fluid culture obtained at <72 hours of age. Clinical and microbiologic characteristics of EOS case infants were obtained by review of medical, laboratory and administrative records. Blood culture, antibiotic initiation and maternal discharge code data were available for all VLBW infants born between 1999 and 2013. RESULT: One-hundred nine EOS cases (20.5/1000 VLBW births) occurred during the study period. Preterm labor, preterm rupture of membranes and/or the obstetrical diagnosis of chorioamnionitis were present in 106/109 cases (97%). Obligate anaerobic organisms accounted for 16% of cases. Time to culture positivity was 36 hours for 88% and 48 hours for 98% of cases. From 1999 to 2013, 97% of VLBW infants were evaluated for EOS and 90% administered empiric antibiotics; 22% of these infants were born by cesarean section to mothers with preeclampsia and without preterm labor or chorioamnionitis and had a 12-fold lower incidence of EOS compared with the remaining infants. CONCLUSION: Decisions to initiate and discontinue empiric antibiotics among VLBW infants can be informed by the delivery characteristics of infected infants and by local microbiologic data.
