Objective: Second and early third-trimester uterine rupture in a non-laboring woman is a very rare and life-threatening condition for both mothers and newborns. However, there are scant epidemiologic data on this event., Study Design: Literature searches using Medical Subject Headings (MeSH) and non-MeSH terms were conducted in the PubMed/MEDLINE, Google Scholar and Embase databases from 1988 to 2020. Abstracts were reviewed and selected if they reported on uterine rupture in the second and third trimester. Uterine rupture was characterized as a full-thickness uterine wall defect. A total of 80 singleton intrauterine pregnancies between gestational ages of 14 and 34 weeks' gestation were included., Results: The mean gestational age at diagnosis of uterine rupture was 22.4 ± 5.4 weeks. The associated events in obstetric history for uterine rupture were: ≥1 previous cesarean section (45%; 36/80 of the cases), previous uterine rupture (10%; 8/80), previous classical uterine incision (7.5%; 6/80), myomectomy (25%; 20/80) and congenital uterine malformations (16.3%; 13/80 of the cases). Uterine ruptures were associated with a short IP interval in 13.7% (11/80) and 43.7% (35/80) were associated with abnormal placentation: placenta accreta spectrum (PAS) disorders ( n  = 26), placenta previa ( n  = 2) and placenta previa and PAS ( n  = 7). The rate of related prenatal ultrasound findings was 67.5%. Cesarean hysterectomy was performed in 27% of the cases. Maternal death was reported in 2.5% (2/80). For the neonates delivered ≥24 weeks' gestation ( n  = 27) peripartum fetal death was reported in 33.3% (9/27)., Conclusions: Midgestational pre-labor spontaneous uterine rupture is not an anecdotal event and may follow the worldwide increasing rate of cesarean sections. Health care providers should be familiar with the associated factors, presenting symptoms and complications of this obstetric emergency.

Due to a concern of severe adverse neonatal and maternal complications, fundal pressure (FP) maneuver has been discouraged by several national obstetric guidelines as well as the World Health Organization. In this manuscript, we argue that previously published evidence pointing to unfavorable effects of FP might not be relevant to the common practice. Our main concern is that the inherent limitations of published studies undermining the association of FP with various obstetric complications, in conjunction with fear of medical-legal implications, might lead to an absolute avoidance of this procedure, with a potential subsequent increase in vacuum-assisted and cesarean deliveries. We suggest establishing standardized guidelines for FP application, intend to prevent application of uncontrollable and aggressive pressure, assist the obstetricians in case of legal claims, and yet to preserve the use of gentle and respectful FP application to benefit the delivery., (© 2022.

Objective: Placenta Accreta Spectrum (PAS) disorders have become a major iatrogenic obstetric complication worldwide. Data on the accuracy of ultrasound examination diagnosis are limited by incomplete confirmation and variability in the description of the different grades of PAS at delivery. The aim of this study was to compare our prenatal routine sonographic screening and diagnostic scoring system with a standardized clinical grading system at birth in patient at risk of PAS., Study Design: This is a retrospective cohort study of 607 pregnant patients with at least one prior cesarean delivery between December 2013 and December 2018. All patients were assessed for PAS using our institutional prenatal sonographic scoring system and the corresponding ultrasound findings were compared with those of a standardized clinical intra-operative macroscopic grading system of the degree of accreta placentation at vaginal birth or laparotomy., Results: PAS was diagnosed clinically at birth in 50 (8.2%) cases, 17 of which were confirmed by histopathology. A low (score ≤ 5), medium (score 6-7), high (score ≥ 8) probability for PAS was reported in 502, 61 and 44 cases, respectively. The probability score increased significantly ( p  < .001) in women ≥2 prior cesarean deliveries, with an anterior low-lying/placenta previa, with absent clear space, increased in retroplacental vascularity and with the size and numbers of lacunae. The number of cases classified clinically as grade 1 (non-PAS) and 3 (adherent PAS) was significantly ( p  < .001) lower in women with a high probability score whereas the rates of the other grades was significantly ( p  < .001) higher. The widest discrepancy between ultrasound probability score and clinical grade was found for grade 2 which, describes a partial placental adherence and grades 4 and 5 which, refer to placental percreta which describes tissue having invade trough the uterine serosa and beyond., Conclusions: Both ends of the spectrum of accreta placentation remain difficult to diagnose antenatal and clinically at birth, in particular when no histopathologic confirmation is available. There is a need to develop ultrasound accuracy score systems that can differentiate between the different grades of PAS and which are validated by standardized clinical and pathology protocols.

Objective: To investigate whether the severity of isolated oligohydramnios at term is associated with increased rates of adverse perinatal outcome., Study Design: A retrospective study conducted in a single medical center from 2017 to 2019. All low-risk pregnancies with incidental isolated oligohydramnios at term were included. The degree of oligohydramnios was arbitrarily classified into mild (AFI = 41-50 mm), moderate (AFI = 21-40 mm) and severe (AFI = 0-20 mm)., Result: A total of 610 women were included: 202 with a mild (33.1%), 287 moderate (47.0%), and 121 severe oligohydramnios (19.8%). Non-reassuring monitor requiring immediate delivery and worse composite neonatal outcome were more common among severe than mild or moderate oligohydramnios (14.0% and 6.4%, 7.3% respectively; p  = .039 and 19.8%, 10.9% and 11.8%, respectively; p  = .048)., Conclusion: Low-risk pregnancies with isolated severe oligohydramnios at term have a higher tendency toward non-reassuring fetal monitoring requiring prompt delivery and adverse neonatal outcomes, this calls for close intrapartum surveillance.

Objectives: The aim of this study is to assess the procedure-to-delivery interval (PDI), the obstetric complications, and the early neonatal outcome in patients that did or did not receive glucocorticosteroids (GCSs) before third-trimester amniocentesis (TTA)., Methods: A retrospectively analysis of 445 TTA procedures divided into two groups based on the administration (study group = 220 patients) or not (control group = 225 patients) of GCSs before TTA. The PDI was calculated for all patients. Obstetric and neonatal outcomes were compared between the groups., Results: The rate of procedure-associated complications was similar between the groups. The mean PDI was 47.2 ± 16.8 days. The overall incidence of preterm birth was 11.7%; 9% delivered between 34 and 37 weeks and 2.7% between 28 and 34 weeks. Only nine patients (2%) delivered within seven days following TTA. The incidence of respiratory distress syndrome in the study and control groups was 1.8% and 1.3%, p  = .71, respectively. There were no significant differences in other neonatal outcomes in term and preterm deliveries between the study and control groups., Conclusions: In the present study, the administration of glucocorticoids prior to TTA did not reduce the rates of neonatal complications, which was similar in both groups and not higher than the general population.

Introduction: Preeclampsia (PE) is a major pregnancy complication, posing considerable morbidity and mortality. The maternal serum angiogenic factors - PlGF and sFlt-1, and their ratio appear to be promising markers to predict PE. Aims: To assess whether the evaluation of PlGF and sFlt-1 adds to the clinical workup of women with suspected PE, and to estimate the cost/benefit., Methods: We prospectively enrolled pregnant women with suspected PE who were admitted to the Maternal-Fetal Medicine Unit (MFM) at Shamir Medical Center. Pregnancy and delivery records were collected from their computerized electronic medical records. PlGF<150pg/ml and sFlt-1/PlGF>38 measured prospectively were used to predict PE., Results: Of 105 women included, 28 were in the control group with unrelated complications and none developed PE. Among 66 women with suspected PE, 27(41%) developed the syndrome, with a positive predictive value (PPV) of 90.3% for PlGF<150 pg/ml and 88.9% for sFlt-1/PlGFabove 38. Out of 11 women with suspected intrauterine growth restriction (IUGR), six developed the syndrome, and among them, the negative predictive value (NPV) was ~ 90%., Conclusions: Angiogenic factors are reliable in predicting PE near delivery. Of 8355 annual deliveries, 584 were admitted for suspected PE. The annual test cost was NIS 66,576 (NIS 140 per single test). Cost-saving was NIS 2.18 million, the ratio of cost saved vs. test cost was 32.7., Discussion: The angiogenic factors are efficient and cost-saving in PE prediction near delivery. A larger study is necessary to determine the inclusion of angiogenic factors in the workup for suspected PE.

Objective: The ideal time for birth in pregnancies diagnosed with vasa previa remains unclear. We conducted a systematic review aiming to identify the gestational age at delivery that best balances the risks for prematurity with that of pregnancy prolongation in cases with prenatally diagnosed vasa previa., Data Sources: Ovid MEDLINE, PubMed, CINAHL, Embase, Scopus, and Web of Science were searched from inception to January 2022., Study Eligibility Criteria: The intervention analyzed was delivery at various gestational ages in pregnancies prenatally diagnosed with vasa previa. Cohort studies, case series, and case reports were included in the qualitative synthesis. When summary figures could not be obtained directly from the studies for the quantitative synthesis, authors were contacted and asked to provide a breakdown of perinatal outcomes by gestational age at birth., Methods: Study appraisal was completed using the National Institutes of Health quality assessment tool for the respective study types. Statistical analysis was performed using a random-effects meta-analysis of proportions., Results: The search identified 3435 studies of which 1264 were duplicates. After screening 2171 titles and abstracts, 140 studies proceeded to the full-text screen. A total of 37 studies were included for analysis, 14 of which were included in a quantitative synthesis. Among 490 neonates, there were 2 perinatal deaths (0.4%), both of which were neonatal deaths before 32 weeks' gestation. In general, the rate of neonatal complications decreased steadily from <32 weeks' gestation (4.6% rate of perinatal death, 91.2% respiratory distress, 11.4% 5-minute Apgar score <7, 23.3% neonatal blood transfusion, 100% neonatal intensive care unit admission, and 100% low birthweight) to 36 weeks' gestation (0% perinatal death, 5.3% respiratory distress, 0% 5-minute Apgar score <7, 2.9% neonatal blood transfusion, 29.2% neonatal intensive care unit admission, and 30.9% low birthweight). Complications then increased slightly at 37 weeks' gestation before decreasing again at 38 weeks' gestation., Conclusion: Prolonging pregnancies until 36 weeks' gestation seems to be safe and beneficial in otherwise uncomplicated pregnancies with antenatally diagnosed vasa previa., (Copyright © 2022 Elsevier Inc.

Introduction: Preterm labor involves about 7.4% of live births in Israel and constitutes over 85% of morbidity and mortality in newborns. Risk factors for preterm labor include a history of preterm delivery shortening of the uterine cervix, cervical procedures, uterine malformations, polyhydramnios, intrauterine growth restriction, preeclampsia, multiple gestations, and more. Progesterone is an essential hormone in the process of fertilization and is involved in the menstrual cycle, implantation and preservation of pregnancy. Due to its various functions in the prevention of preterm labor, the use of progesterone as a preventive treatment has been extensively studied since the second half of the last century and tested in various forms of administration, mainly intramuscular injection and vaginal root. For years, women with a history of preterm labor were treated with intramuscular progesterone once a week between 16 to 36 weeks' gestation or until birth. Recently, vaginal progesterone treatment was initiated in women with cervical length > 25 mm measured by ultrasound between 18-24 weeks gestation. Studies have shown that progesterone treatment reduces the incidence of preterm labor given in the proper indication. This update overview examines progesterone treatment for the prevention of preterm labor.

Objectives: To evaluate the new ultrasound-based signs for the diagnosis of post-cesarean section uterine niche in nonpregnant women., Methods: We investigated prospectively a cohort of 160 consecutive women with one previous term cesarean delivery (CD) between December 2019 and 2020. All women were separated into two subgroups according to different stages of labor at the time of their CD: subgroup A (n = 109; 68.1%) for elective CD and CD performed in latent labor at a cervical dilatation (≤4 cm) and subgroup B (n = 51; 31.9%); for CD performed during the active stage of labor (>4 cm)., Results: Overall, the incidence of a uterine niche was significantly (P < .001) higher in women who had an elective (20/45; 44.4%) compared with those who had an emergent (21/115; 18.3%) CD. Compared with subgroup B, subgroup A presented with a significantly (P = .012) higher incidence of uterine niche located above the vesicovaginal fold and with a significantly (P = .0002) lower proportion of cesarean scar positioned below the vesicovaginal fold. There was a significantly (P < .001) higher proportion of women with a residual myometrial thickness (RMT) > 3 mm in subgroup A than in subgroup B and a significant negative relationship was found between the RMT and the cervical dilatation at CD (r = -0.22; P = .008)., Conclusions: Sonographic cesarean section scar assessment indicates that the type of CD and the stage of labor at which the hysterotomy is performed have an impact on the location of the scar and the scarification process including the niche formation and RMT., (© 2021 American Institute of Ultrasound in Medicine.)

Objective: To evaluate the incidence of chromosomal aberrations and the clinical outcomes following the prenatal diagnosis of isolated perimembranous ventricular septal defect (pVSD)., Methods: This retrospective study was composed of a cohort of pregnant women whose fetuses were diagnosed with isolated pVSD. Complete examinations of the fetal heart were performed, as well as a postnatal validation echocardiography follow-up at 1 year of age. The collected data included: spontaneous closure of the pVSD, need for intervention, chromosomal aberrations and postnatal outcome., Results: Fifty-five pregnant women were included in the study. 34/55 (61.8%) of the fetuses underwent prenatal genetic workup which revealed no abnormal results. No dysmorphic features or abnormal neurological findings were detected postnatally in those who declined a prenatal genetic workup during the follow-up period of 2 years. In 25/55 of the cases (45.4%), the ventricular septal defects (VSD) closed spontaneously in utero, whereas in 17 cases of this group (30.9%) the VSD closed during the first year of life. None of the large 3 VSDs cases (>3 mm), closed spontaneously., Conclusion: Prenatally isolated perimembranous VSD has a favorable clinical outcome when classified as small-to-moderate size, children in our cohort born with such findings had no macroscopic chromosomal abnormalities., (© 2022 The Authors.

Objective: To determine the clinical pregnancy rate following sequential hydrosonography and hysterosalpingo-foam sonography (HyFoSy) in tubal patency assessment among women undergoing infertility work-up., Study Design: Prospective follow-up of women referred to our department between July 2019 and October 2020. Sequential hydrosonography and HyFoSy were carried out., Results: Out of 250 having the procedure, 100 women were excluded from study due to limited infertility, semen abnormal or not examined, evaluation for social egg freezing or they were single. Of the remaining 150 women, 48 (32%) conceived during a 10-24 months follow-up period: 17 (11%) conceived naturally and 7 (4.7%) by IUI. The mean time to conception was 5.5 ± 5.4 months and the pregnancy rate was 52% within 6 months. Among the spontaneous pregnancies 47% occurred within a month and 76% within 3 months., Conclusion: Sequential hydrosonography and HyFoSy is a promising method for assessing the uterine cavity and tubal patency in women undergoing infertility workup. The findings suggest that the procedure may increase the chance of a spontaneous pregnancy following the procedure. Given the other known advantages of sequential hydrosonography and HyFoSy, this test is worth including in the initial workup for infertile patients., (Copyright © 2022 Elsevier B.V.

Background: Suspicion of retained products of conception (RPOC) often arises after delivery and still poses a diagnostic and management challenge., Purpose: To prospectively evaluate a sonographic classification for the management of patients with suspected RPOC after delivery., Material and Methods: Based on grayscale and Doppler ultrasound parameters, patients were classified into high, moderate, or low probability of RPOC. For the low and moderate probability groups, an ultrasound follow-up at the end of the puerperium was recommended. For the high probability group, a follow-up examination was conducted 10-14 days after the first ultrasound, and patients with persistent high probability findings were referred for surgical intervention., Results: The sample was composed of 215 patients at risk of RPOC. Of these, 100, 93, and 22 patients were classified as having a low, moderate, or high probability of RPOC, respectively. Rates of RPOC were 55%, 2%, and 2% in the high, moderate, and low probability categories, respectively. When the categorization was based on the most recent ultrasound obtained during the puerperium, the adjusted RPOC prevalence rates were 71% in the high, 6% in the moderate, and 0% in the low probability groups., Conclusion: This study confirms the effectiveness of our sonographic classification for managing patients with suspected RPOC after delivery. In all three categories, it is recommended to adhere to a conservative management protocol in clinically stable women until the end of the puerperium. This approach provides good predictability for RPOC and can reduce unnecessary surgical interventions.

Research Question: What is the efficacy of sequential two-dimensional transvaginal ultrasound (2D-US) and hysterosalpingo-foam sonography (HyFoSy) after methotrexate (MTX) treatment for tubal pregnancy among patients who desire a future pregnancy?, Design: A prospective trial conducted between May 2019 and November 2020. Patients who had a suspected tubal ectopic pregnancy diagnosed by ultrasound and treated by MTX were included. These patients underwent sequential transvaginal 2D-US assessment of the pelvic organs and a complementary HyFoSy for tubal patency. The primary outcome was tubal obstruction in the affected side., Results: A total of 360 women underwent sequential transvaginal 2D-US assessment of the pelvic organs and a complementary HyFoSy for tubal patency. Of these, 40 (11.1%) women fulfilling the inclusion criteria were enrolled. In six out of 40 (15%), hydrosalpinx of the affected tube was found during the initial transvaginal ultrasound examination and were excluded from further investigation. In the remaining 34 (85%) patients, HyFoSy was carried out. Tubal block was found in 10 out of 34 (29.4%) patients. Of these, eight out of 34 (23.5%) and two out of 34 (5.9%) had a proximal block of the affected tube and bilateral proximal obstruction, respectively. Hysterosalpingography confirmed the tubal obstruction in all the affected cases. No procedure-related complications were documented., Conclusions: Forty per cent of women who were treated by MTX for tubal pregnancy were diagnosed with tubal obstruction. We recommend that sequential transvaginal ultrasound and HyFoSy become part of routine follow-up for these women, thus offering them timely referral to the appropriate specialist., (Copyright © 2021 Reproductive Healthcare Ltd.

Objectives: A comparative examination of the clinical, laboratory, ultrasound findings, and operative characteristics of rare site located ectopic pregnancies., Methods: Retrospective analysis of all department cases of rare site located ectopic pregnancies diagnosed and treated from December 2006 to December 2019., Results: Thirty rare ectopic pregnancies were identified. Of these, 11 were ovarian, 10 were interstitial and 9 were tubal stump. The patients treated for ovarian pregnancy had significantly lower human chorionic gonadotropin (hCG) levels than patients treated for interstitial or stump pregnancies (2025 ± 1105 mIU/ml, 18,424 ± 2579 mIU/ml and 11,204 ± 9221 mIU/ml, respectively, p = 0.003). The main presenting symptom in patients with an ovarian pregnancy was abdominal pain (90.9%, 60.0% and 44.4%, respectively, p = 0.031). Signs of abdominal peritoneal irritation (i.e., rebound tenderness and guarding) were more frequent upon physical examination in patients with an ovarian pregnancy (72.2%, 30.0% and 22.2%, respectively, p = 0.044) who also exhibited the highest rates of syncope and hypovolemic shock upon admission compared to patients with an interstitial or stump pregnancy (54.5%, 10.0% and 11.1%, respectively, p = 0.031). Ovarian pregnancies were associated with the lowest sonographic detection rates (9.1%, 80.0% and 100%, respectively, p = 0.0001) and with free fluid in the pouch of Douglas (72.7%, 20.0% and 22.2%, respectively, p = 0.02). Ovarian pregnancies experienced the highest rupture rate during surgery compared to interstitial or stump pregnancies (66.9%, 16.7% and 44.4%, respectively, p = 0.028), had a significantly higher estimated blood loss (1081 ± 647 ml, 760 ± 597 ml and 343 ± 318 ml, respectively, p = 0.003) and required blood transfusions in the perioperative period (63.6%, 20.0% and 11.1%, respectively, p = 0.025) significantly more often., Conclusions: Ovarian pregnancy remains the most challenging diagnosis compared to interstitial and tubal stump ectopic's. Health care providers should recognize these rare site ectopic pregnancies and to handle these gynecological emergencies promptly., (Copyright © 2021 Elsevier Inc. All rights reserved.)

This systematic review and meta-analysis evaluated the diagnostic accuracy of hysterosalpingo-foam sonography in suspected cases of tubal occlusion. The combined sensitivity and specificity estimates were 0.99 (95% confidence interval [CI], 0.89-0.99) and 0.91 (95% CI, 0.53-0.98), respectively, with positive and negative likelihood ratios of 11.5 (95% CI, 1.5-87.5) and 0.006 (95% CI, 0.0003-0.12), respectively. The diagnostic odds ratio was 1931.008 (95% CI, 69.7-53,460.8). These findings confirm hysterosalpingo-foam sonography as a highly accurate test for the diagnosis of tubal occlusion and show that it is on a par with standard tests., (© 2020 American Institute of Ultrasound in Medicine.)

Study Objective: To evaluate the efficacy of flushing the uterine cavity with lidocaine before hysterosalpingo-foam sonography (HyFoSy) to reduce procedure-related pain., Design: A double-blind randomized controlled trial was conducted at the Department of Obstetrics and Gynecology, Shamir Medical Center, Israel between June 2020 and September 2020 involving 80 women undergoing a HyFoSy procedure., Setting: University-affiliated medical center., Patients: A total of 40 women were assigned randomly to the lidocaine group and 40 to the saline (placebo) group using a predetermined randomization code. Intrauterine instillation before the procedure consisting of either lidocaine 2% or normal saline alone was conducted, respectively., Interventions: The primary outcome measure was the visual analog scale (VAS) pain score during the phase of intrauterine foam instillation reported by the women after the procedure. The VAS consisted of a 10-cm line ranging from 0 to 10 (anchored by 0 = no pain and 10 = very severe pain). On the basis of the VAS scores, the pain level ratings were classified as mild (rated 1-3), moderate (4-6), or severe (7-10)., Measurements and Main Results: The patient characteristics and obstetric data were found to be similar in both groups. Comparison of the VAS pain scores experienced during the procedure showed that women in the lidocaine flushing group rated the procedure less painful than the women in the saline group (3.0 ± 1.3 vs 6.3 ± 1.5, respectively; p = .001). The incidence of severe pain was significantly lower in the lidocaine group than the saline group (2.5% and 45.0%, respectively, p = .001)., Conclusion: Lidocaine flushing of the uterine cavity before HyFoSy significantly decreased the pain known to be caused by this procedure and had the advantage of no side effects. It is easily applied, relatively inexpensive, and may affect compliance with this procedure., (Copyright © 2020 AAGL. Published by Elsevier Inc. All rights reserved.)

Pregnant women may be at higher risk of severe complications associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which may lead to obstetrical complications. We performed a case control study comparing pregnant women with severe coronavirus disease 19 (cases) to pregnant women with a milder form (controls) enrolled in the COVI-Preg international registry cohort between March 24 and July 26, 2020. Risk factors for severity, obstetrical and immediate neonatal outcomes were assessed. A total of 926 pregnant women with a positive test for SARS-CoV-2 were included, among which 92 (9.9%) presented with severe COVID-19 disease. Risk factors for severe maternal outcomes were pulmonary comorbidities [aOR 4.3, 95% CI 1.9-9.5], hypertensive disorders [aOR 2.7, 95% CI 1.0-7.0] and diabetes [aOR2.2, 95% CI 1.1-4.5]. Pregnant women with severe maternal outcomes were at higher risk of caesarean section [70.7% (n = 53/75)], preterm delivery [62.7% (n = 32/51)] and newborns requiring admission to the neonatal intensive care unit [41.3% (n = 31/75)]. In this study, several risk factors for developing severe complications of SARS-CoV-2 infection among pregnant women were identified including pulmonary comorbidities, hypertensive disorders and diabetes. Obstetrical and neonatal outcomes appear to be influenced by the severity of maternal disease.

Aim: Ectopic pregnancy implantation on the tubal stump after salpingectomy is a rare location for extrauterine pregnancy, whose pathogenesis is still unknown. The purpose of this study was to examine whether the time interval elapsed from salpingectomy may predispose the embryo to implantation on the tubal stump in the next pregnancy subsequent to tube removal., Methods: Nine women operated for stump pregnancy (study group) between 2008 and 2019 were retrospectively identified. For each case in the study group, 12 consecutive cases that underwent laparoscopic salpingectomy constituted the control group. A sample size of 100 control patients was calculated to achieve statistical power (97.8%) and an α of 0.05. The control groups were triple-matched with the study group for patients' age, indications for salpingectomy (tubal pregnancy or hydrosalpinx prior to in vitro fertilization treatment) and mode of conception of the subsequent pregnancy following salpingectomy., Results: Nine women underwent surgery for stump pregnancy during the study period. All women had a surgical history of laparoscopic salpingectomy. The time interval from prior salpingectomy to subsequent pregnancy was significantly shorter in study group than in the control group (4.3 ± 2.1 months vs. 15.6 ± 13.7 months, respectively, p = 0.016)., Conclusion: A possible association between the short time interval from prior salpingectomy to ectopic implantation on the tubal stump in the subsequent pregnancy was found. The clinical implications of these findings and in particular whether patients should be advised to wait at least 4 months from the salpingectomy to the subsequent pregnancy remain unclear., (© 2021 Japan Society of Obstetrics and Gynecology.)

Purpose: Preterm birth is the leading cause of perinatal morbidity and mortality. Vaginal progesterone cervical cerclage and Arabin cervical pessary are considered as preventive treatments in women at risk for preterm birth. However, there is less evidence as to which of these interventions is the preferred management. The current study aims was to compare the outcome of pregnancy in women with a short cervical length managed with 4 different treatment protocols: therapy with vaginal progesterone, cervical cerclage and an Arabin cervical pessary (group A), Arabin cervical pessary and vaginal progesterone (group B), cervical cerclage and vaginal progesterone (group C), or vaginal progesterone alone (group D)., Methods: A retrospective cohort study of singleton pregnancies managed in three tertiary medical centers between September 2011 and December 2017., Results: In the study period, 286 pregnant women underwent vaginal ultrasonography between 15 and 29 weeks gestation. They all had a short cervical length (≤25 mm). Of these, 18 (6.3%), 120 (41.9%), 38 (13.3%) and 110 (38.5%) patients received treatment classifying them into groups A, B, C, and D, respectively. A significantly higher rate of patients in group A had either a history of cervical incompetence (44.4 versus 9.2 versus 7.9 and 0.9%, respectively, p = .0001) or a cervical procedure (61.1 versus 37.5 versus 28.9 and 27.3%, respectively, p = .027) compared to patients in group B, C, and D. Despite having a shorter cervical length at recruitment in group A (median (range); 14.5 (0-25) versus 15 (0-25) versus 15.5 (0-25) and 19 (2-25) mm, respectively, p = .002) the rate of spontaneous preterm delivery <37-week gestation was similar across groups (44.4 versus 32.5 versus 36.8 versus 32.7%, respectively, p = .665)., Conclusion: A combined rescue therapy involving vaginal progesterone, cervical cerclage, and Arabin cervical pessary emerges as a promising management strategy in pregnant women who have a short cervical length and a high background risk for preterm delivery. This combination may prolong their pregnancy and safely bring them near term. Additional studies are needed to confirm these preliminary findings.

Study Objective: To describe the incidence of ovarian dermoid cysts associated with paraneoplastic encephalitis syndrome due to N-methyl-D-aspartic acid (NMDA) receptor antibodies among women undergoing surgical resection of dermoid cysts., Design: Retrospective cohort study., Setting: University-affiliated department of obstetrics and gynecology., Patients: All patients with pathology-proven ovarian dermoid cysts who underwent surgical resection in our department between January 2008 and December 2019. Their demographic, clinical, and surgical characteristics are described, with emphasis on cases diagnosed with anti-NMDA receptor encephalitis., Interventions: Ovarian dermoid cyst resection by cystectomy or salpingo-oophorectomy., Measurements and Main Results: A total of 233 patients were operated on for ovarian dermoid cysts, comprising 2 cases diagnosed with anti-NMDA receptor encephalitis (0.85%). Among the women without NMDA receptor encephalitis, the mean age was 33.3 ± 14.9 years, 84.0% were of reproductive age, 5.2% were premenarchal, and 10.8% were menopausal. The mean diameter of the dermoid cyst in this group was 77.3 ± 33.3-mm. The 2 patients diagnosed with anti-NMDA receptor encephalitis were 21 years old and 42 years old. The diameters of their dermoid cysts were 15-mm and 80-mm, respectively. The patients with anti-NMDA receptor encephalitis were managed with laparoscopic resection, plasmapheresis, intravenous immunoglobulins, and corticosteroids; 1 patient also received immunosuppressive treatment. Both recovered without significant neurologic sequela., Conclusion: Paraneoplastic syndrome due to NMDA receptor antibodies is a rare complication of dermoid cysts. This complication may occur in younger or older women, as well as in small- or large-diameter cysts. Thus, a high index of suspicion is required to correctly diagnose and treat women presenting with neurologic symptoms in the presence of dermoid cysts., (Copyright © 2020.

Background: To evaluate the efficacy of virtual reality (VR) as a distraction technique in the management of acute pain and anxiety during amniocentesis., Study Design: A randomized controlled trial was conducted between September 2020 and October 2020 involving 60 women undergoing mid-trimester amniocentesis. Thirty women were assigned randomly to the VR intervention (immersive video content as a distraction method) group and 30 to the standard care group using a predetermined randomization code. The primary outcome measure was the visual analog scale (VAS) pain score, along with the women's ratings of their extent of anxiety experienced during the procedure. The VAS consisted of a 10 cm line ranging from 0 to 10 (anchored by 0 = no pain and 10=very severe pain). Anxiety was assessed on Spielberger's state-trait anxiety inventory (STAI) questionnaire., Results: The patients' characteristics and obstetric data were similar in both groups. The ratings on the VAS indicated that the VR intervention was associated with significantly less pain than the ratings in the standard of care group; namely, 2.5 ± 1.5 vs. 3.8 ± 1.7, respectively (95 % CI 0.44-2.13; p = 0.003). There were no significant differences in maternal anxiety levels before and after amniocentesis., Conclusion: The VR intervention as a distractive technique emerged as effective in reducing pain during amniocentesis. It is easy to use, relatively inexpensive, has the advantage of no serious side effects, and may decrease the fear of pain that can affect patients' experiences and compliance with this procedure., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier B.V.

Introduction: The COVID-19 pandemic posed unique challenges to medical teams in general and in the field of obstetrics in particular, where the provision of medical services could not be postponed. Optimal care during the COVID-19 outburst required rapid adjustment to changes, ensuring staff and patients' safety while maintaining close and direct contact with patients., Objectives: To explore obstetricians' experiences during the first outburst, focusing on their challenges, needs and ways of coping., Methods: Semi-structured in-depth interviews were conducted online with 13 senior physicians and residents (7 women, 6 men) from four hospitals, who worked in obstetrics. The interviews were analyzed using the Immersion/Crystallization method developed in medicine focused on their experiences., Results: The findings revealed that alongside the impressive mobilization of the teams during this period, physicians encountered various challenges. These included being overwhelmed with the ever-changing and often conflicting guidelines; a feeling of lack of transparency and loss of trust in the system that did not always protect them nor provided their basic needs; difficulty in maintaining daily needed routines, such as communication within the team; dealing with patients' and their families anxiety; and striving to maintain a positive childbirth atmosphere along with having to set boundaries and keep distance. The teams felt the need for training in dealing with patients' and staff's emotional needs as well as finding ways to maintain a professional-friendly relationship among team members., Conclusions: The COVID-19 period forced obstetricians to change procedures and conduct themselves differently. They demonstrated a great commitment to assuring that women have a positive childbirth experience, even within the limitations of COVID. They experienced great difficulty as they themselves were dealing with fears of the virus, distancing from others, and addressing new emerging needs., Discussion: Reports from around the world and the findings of the current study indicate the importance of developing processes that will enhance physicians' and patients' trust, to allow physicians to feel safe and cared for and to be able to provide high-quality care Identifying the challenges, needs and strengths of the medical teams can help in dealing with this and future pandemics. This requires caring for physicians, as individuals, as family members, as team members, along with provision of training that can help them communicate well to provide high-quality safe care.

Objective: During the 2020 COVID-19 pandemic there was a decrease in emergency room arrivals. There is limited evidence about the effect of this change in behavior on women's health. We aimed to evaluate the impact of the COVID-19 pandemic on the diagnosis, treatment and complications of women presenting with a tubal Ectopic Pregnancy (EP)., Study Design: This is a single centre retrospective cohort study. We compared the clinical presentation, treatment modalities and complications of all women presenting in our institution with a tubal EP during the COVID-19 pandemic between 15 March and 15 June 2020, with women who were treated in our institution with the same diagnosis in the corresponding period for the years 2018-2019., Results: The study group included 19 cases of EP (N = 19) that were treated between the 15 March 2020 and 15 June 2020. The control group included 30 cases of EP (N = 30) that were admitted to in the corresponding period during 2018 and 2019. Maternal age, parity, gravity and mode of conception (natural vs. assisted) were similar between the two groups. There was no difference in the mean gestational age (GA) according to the last menstrual period. In the study group more women presented with sonographic evaluation of high fluid volume in the abdomen than in the control group (53 % vs 17 %, P value 0.01). This finding is correlated with a more advanced disease status. In the study group there was a highly statistically significant 3-fold increase in rupture among cases (P < 0.005) and a 4-fold larger volume of blood in the entrance to the abdomen (P < 0.002). We found that there were no cases of ruptured EP in the group of women who were pregnant after assisted reproduction., Conclusion: We found a higher rate of ruptured ectopic pregnancies in our institution during the COVID-19 pandemic. Health care providers should be alerted to this collateral damage in the non-infected population during the COVID-19 pandemic., Competing Interests: Declaration of Competing Interest None., (Copyright © 2021 Elsevier B.V.

Objective: We examined the potential value of combining ultrasound and non-invasive prenatal screening (NIPS) of maternal blood to screen for major aneuploidies as an early approach before selective fetal reduction from twin pregnancy to singleton., Study Design: The sample was composed of pregnant women with di-chorionic di-amniotic twins who chose to undergo fetal reduction to singleton at 12-24 weeks of gestation. These women were asked to provide a blood sample for cell-free fetal DNA (cffDNA) testing prior to fetal reduction., Results: A total of 24 pregnant women with a twin pregnancy prior to fetal reduction to singleton were enrolled. There were 8 cases with structural anomalies (33.3%) in one twin that dictated fetal reduction. The proportion of patients who underwent selective fetal reduction for fetal abnormalities was larger than in several other studies. The NIPS identified 1 case of Trisomy 13 (4.2%). The other 15 cases (62.5%) had no structural or chromosomal anomalies. The decision to undergo elective reduction of twin pregnancy to singleton was made for social reasons or upon the parents' request. Given the 33% of structural anomalies in the cohort, a cost analysis indicated that this procedure was 6.6-fold less expensive (vs. 4.6-fold with 4% structural anomalies in other publications) than conducting invasive procedures for the entire cohort., Conclusion: The findings suggest that an early anatomical scan and cffDNA can increase the overall safety margin and reduce interventional procedures before elective reduction of twin pregnancy to singleton. However, a larger cohort is needed to confirm these results., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier B.V.

Background: Second-trimester and early third-trimester uterine rupture in a nonlaboring woman is a very rare and life-threatening condition for both mothers and newborns. We aimed to present clinical characteristics, prenatal findings, and maternal and neonatal outcomes following second-trimester and early third-trimester spontaneous antepartum uterine rupture in our institute., Method: The medical records of all women with full-thickness second-trimester and early third-trimester uterine rupture treated in our department from 1988 to 2019 were retrieved from the institutional database and reviewed. Small uterine defects, incomplete ruptures, and silent uterine incision dehiscence were excluded., Results: From 1988 to 2019, 213 665 deliveries were recorded in our institute. Of these, 12 patients experienced second-trimester or early third-trimester spontaneous uterine rupture. Obstetric history revealed that 50% of the women in each period had undergone previous classical uterine incisions and 50% had a short interpregnancy (IP) interval. The mean age at diagnosis of uterine rupture was 26.3 ± 5.1 weeks. The ruptures were associated with abnormal placentation in 10 cases (83.3%): placenta previa (n = 7); and placenta previa and percreta (n = 3). No maternal mortality occurred. Seven of the 10 (70%) viable newborns survived., Conclusions: The increasing rates of cesarean births (CB) may lead to iatrogenic complications including midgestational prelabor spontaneous uterine rupture, an obstetric emergency, which is hard to diagnose. Maternal and neonatal outcomes can be optimized by a greater awareness of the risk factors, recognition of clinical signs and symptoms, and the availability of ultrasound to assist in establishing a diagnosis to enable prompt surgical intervention., (© 2020 Wiley Periodicals LLC.)

Objective: The 2020 COVID-19 pandemic has been associated with excess mortality and morbidity in adults and teenagers over 14 years of age, but there is still limited evidence on the direct and indirect impact of the pandemic on pregnancy. We aimed to evaluate the effect of the first wave of the COVID-19 pandemic on obstetrical emergency attendance in a low-risk population and the corresponding perinatal outcomes., Study Design: This is a single center retrospective cohort study of all singleton births between February 21 and April 30. Prenatal emergency labor ward admission numbers and obstetric outcomes during the peak of the first COVID-19 pandemic of 2020 in Israel were compared with the combined corresponding periods for the years 2017 to 2019., Results: During the 2020 COVID-19 pandemic, the mean number of prenatal emergency labor ward admissions was lower, both by daily count and per woman, in comparison to the combined matching periods in 2017, 2018, and 2019 (48.6 ± 12.2 vs. 57.8 ± 14.4, p  < 0.0001 and 1.74 ± 1.1 vs. 1.92 ± 1.2, p  < 0.0001, respectively). A significantly ( p  = 0.0370) higher rate of stillbirth was noted in the study group (0.4%) compared with the control group (0.1%). All study group patients were negative for COVID-19. Gestational age at delivery, rates of premature delivery at <28, 34, and 37 weeks, pregnancy complications, postdate delivery at >40 and 41 weeks, mode of delivery, and numbers of emergency cesarean deliveries were similar in both groups. There was no difference in the intrapartum fetal death rate between the groups., Conclusion: The COVID-19 pandemic stay-at-home policy combined with patient fear of contracting the disease in hospital could explain the associated higher rate of stillbirth. This collateral perinatal damage follows a decreased in prenatal emergency labor ward admissions during the first wave of COVID-19 in Israel., Key Points: · Less obstetrical ER attendance is observed during the pandemic.. · There is a parallel increase in stillbirth rate.. · Stillbirth cases tested negative for COVID-19.. · Lockdown and pandemic panic are possible causes.., Competing Interests: None declared., (Thieme.

Background: Determination of the clinical characteristics associated with adnexal torsion involving paraovarian cysts in pediatric and adolescent populations., Methods: Retrospective review of all cases of paraovarian cysts operated on in our department between 2007 and 2019. Demographic characteristics, clinical and sonographic findings were reviewed., Results: The cohort was composed of 39 pediatric and adolescent patients with an operative diagnosis of adnexal masses located in the paraovarian area. The patients were classified into two groups: 19 girls (48.7%) with a confirmed operative diagnosis of adnexal torsion and 20 girls (51.3%) without torsion. The preoperative diagnosis of adnexal torsion was correct in ≈70% of the cases. The mean BMI were similar in both groups. The preoperative sonographic detection rate of paraovarian cysts was also similar (11/19 [57.9%] vs. 14/20 [70.0%]; P = 0.514). The mean cyst diameter did not differ between groups, nor did the classification into cyst size groups (≤50 mm, 51-99 mm and ≥100 mm)., Conclusion: Adnexal torsion is a common complication diagnosed in girls undergoing surgery for paraovarian cysts, and is not associated with sonographic appearance or cyst diameter. In order to prevent torsion, surgical removal of paraovarian cysts should thus be considered in young girls undergoing surgery for paraovarian cysts., Type of Study: Retrospective case series., Level of Evidence: IV., (Copyright © 2020 Elsevier Inc.

Objectives: The study aimed to assess the fetal heart defects that led to termination of pregnancy (TOP), the weeks' gestation that the defect was first diagnosed, whether TOP was conducted and the timeline of events that led to the decision. This is in order to encourage pregnant women to conduct sonographic screening tests that are recommended during pregnancy., Methods: All pregnant women with singleton pregnancy who underwent TOP in our institute because of fetal heart defects as an only finding between 2000-2017 were included. TOPs preformed because of multisystem defects, abnormal karyotype and chromosomal or genetic defect were excluded. The patients were stratified into late TOP (≥24 weeks' gestation) and early TOP (<24 weeks' gestation)., Results: There were 3469 TOP and 228 (6.5%) cases because of fetal heart defects as the only abnormal finding. Of these cases, 191 (83.7%) and 37 (16.3%) were conducted before and after 24 weeks' gestation respectively. The mean weeks' gestation during which the heart defect was first diagnosed and TOP was conducted was 18.7±4.1 and 20.6± 3.7 respectively. The single most common heart defect was of the ventricular outflow tract that was found in 102 cases (44.7%), followed by functionally univentricular heart in 79 cases (34.6%). A combination of two defects was found in 5 cases (2.2%) and was mostly diagnosed after 24 weeks' gestation. Out of all cases 16.8% did not go through early fetal anomaly scan (conducted between 14-16 weeks' gestation), compared to 66.7% of late TOP cases; 22.2% of cases were not diagnosed during routine anomaly scans., Conclusions: In most cases the fetal heart defect was diagnosed during routine 14-16 gestational weeks anomaly scan., Discussion: This information should encourage pregnant women to perform timely sonographic scanning.

Objective: In 2011, the Israeli Ministry of Health (MOH) published standard guidelines for the follow-up of pregnant women infected by CMV, recommending that amniocentesis be performed in cases of maternal serum viral seroconversion or abnormal sonographic findings suggestive of CMV, in order to prove fetal infection before electing for pregnancy termination., Methods: A retrospective cohort study was performed, describing 448 pregnant women from 2006 to 2017. We collected data from all women that elected to continue their pregnancies after seroconversion and also of those who chose to undergo pregnancy termination. Subsequently, a telephone survey was then conducted to record outcomes of the newborns of women with CMV seroconversion during pregnancy., Results: 325 (73%) women chose to continue their pregnancy, while 123 (27%) opted for termination of pregnancy. We found that pregnancy termination due to CMV infection was reduced by 7%, from 72 cases (32%) to 51 cases (25%) after the implementation of the MOH guidelines in 2011. In addition, 182/305 (60%) of women responded to our telephone questionnaire regarding newborn outcomes. Of these women, 45/305 (14%) reported complications, and no correlation was found between the prenatal findings and postnatal outcome among those who have responded to our survey., Conclusion: Implementation of the new MOH guidelines has reduced the rate of pregnancy termination, without increasing the rate of neonatal complications in Israel with a similar outcome of complication rate as reported in the literature., (© 2020 S.

Background: Adnexal torsion in pregnancy is often associated with functional adnexal cysts, especially in pregnancies conceived by ovulation induction (OI) or in-vitro fertilization (IVF). During laparoscopy for adnexal de-torsion, drainage of the functional cysts can be attempted, although this procedure may cause bleeding., Objectives: To investigate the characteristics of ovarian torsion in pregnancy associated with functional cysts and to compare the rate of torsion recurrence following de-torsion alone versus cyst drainage., Methods: All cases of surgically diagnosed adnexal torsion occurring during pregnancy between January 2007 and April 2019 in our department were retrospectively analyzed. The cases of torsion associated with presumed functional ovarian cysts were selected. The rate of recurrent torsion during the same pregnancy was compared for de-torsion alone versus de-torsion and cyst aspiration., Results: Of the 113 women who experienced adnexal torsion during pregnancy, 71 (67.0%) of torsion cases were caused by presumed functional ovarian cysts. Among women with torsion of functional ovarian cysts, the rate of torsion recurrence was significantly higher in patients who underwent de-torsion alone (n=28) compared to women who underwent aspiration and drainage of the ovarian cysts (n=43) (14.3% vs. 0, P = 0.021). There were no cases of intra- or post-operative bleeding in the study cohort., Conclusions: Functional ovarian cysts are the most common adnexal pathology encountered in pregnant women with torsion. Intra-operative cyst aspiration and drainage may reduce the risk of recurrent torsion. Further multi-center studies are required to validate our data prospectively.

Introduction: Preterm labor is defined as delivery before 37 weeks of gestation. Up to 17% of twin pregnancy are preterm. Arabin cervical pessary has been proven as preventing preterm labor in singleton pregnancies. The benefit of it in twin pregnancy is controversial., Objectives: The purpose of this study was to compare the rate of preterm delivery in twin gestation with short cervical length in Israel- one center utilized the combined treatment of Arabin cervical pessary and vaginal progesterone (study group) and the others utilized vaginal progesterone approach (control group)., Methods: Multi-center retrospective cohort study, including "Shamir", "Wolfson", "Shaare Zedek" and "Galilee" medical centers, between the years 2012-2016. Inclusion criteria were twin gestations and short cervical length (<25mm) between 16-28 weeks' gestation., Results: The study group included 68 women, the control group 78 women. The study group had shorter cervical length at intervention in comparison to the control group (13.6 ± 5.9 vs. 16.5 ± 5.7, respectively, p = .002). The treatment started later for the study group compared to the control group (23.2 +2.2 vs 22.6 +3.0)., Conclusions: Despite having shorter cervical length at recruitment, the rate of spontaneous delivery < 34-weeks' gestation was similar in both groups (36.8 vs. 37.2%, respectively)., Discussion: Considering the conclusion in this research it seems that the combination of the mechanical effect of the pessary by embracing the cervix, keeping the cervical mucus, bending it in a way that the pressure is towards the anterior cervical wall together with the progestative effect which increases the estrogen/progesterone ratio, creating uterine quiescence and keeping the structural connective tissue of the cervix have an added benefit. It seems that the combined use of Arabin cervical pessary and vaginal progesterone in twin pregnancy with short cervical length have a synergic effect which may have a benefit in preventing preterm labor. The combination of cervical pessary and progesterone does not negatively affect twin pregnancy outcome and does not cause preterm birth.

Background: Epidemiological data on obstetric and oncologic complications in twin pregnancies combining a complete hydatidiform mole (CHM) coexisting with a normal fetus and placenta are limited., Objectives: To evaluate perinatal and obstetric outcomes for mother and fetus and risk of gestational trophoblastic neoplasia (GTN) in twin pregnancies including a CHM., Search Strategy: PubMed, MEDLINE and EMBASE and the grey literature were searched for articles published between May 1980 and May 2019 using a protocol designed a priori and registered on PROSPERO (CRD42018112524)., Selection Criteria: Observational cohort studies of four or more cases confirmed by histopathology and providing data on pregnancy outcomes and GTN., Data Collection and Analysis: Two reviewers independently reviewed abstracts and full-text articles. The quality of the studies was assessed with the Newcastle-Ottawa scale and a meta-analysis was performed., Main Results: Of the 344 abstracts identified, 14 studies (244 cases) met the eligibility criteria. The incidence of maternal complication in ongoing pregnancies was 80.8% and included vaginal bleeding, hyperthyroidism and pre-eclampsia. There were overall 91 (50%) live births in ongoing pregnancies and 83 (34%) of the total cases were subsequently diagnosed with GTN. Substantial and significant (P < 0.001) heterogeneity was found for the incidence of preeclampsia indicating variability in reporting the incidence of some obstetric complications between studies., Conclusions: Patients diagnosed with a twin pregnancy combining a CHM and an apparently normal fetus have a high risk of perinatal complications, low live-birth rates and around a third of them will develop a GTN and should be managed by specialised multidisciplinary teams., Tweetable Abstract: Our study indicates a high rate of obstetric and oncologic complications in patients presenting with a complete hydatidiform mole and coexistent normal fetus., (© 2020 The Authors.

Purpose : To compare the rate of preterm delivery in pregnant women with a short cervical length managed with Arabin cervical pessary and vaginal progesterone versus vaginal progesterone alone. Methods: This was a retrospective cohort study of singletons pregnancies managed in two tertiary medical centers between September 2011 and May 2017. One center utilized the combined treatment of Arabin cervical pessary and vaginal progesterone (study group) and the second utilized vaginal progesterone approach (control group). Results: During the study period, a total of 202 pregnant women who underwent vaginal ultrasonography between 15 and 29 weeks gestation. They all had short cervical length (≤25 mm). Among them, 94 (46.5%) and 108 (53.5%) patients were in the study and control group, respectively. A significantly higher rate of patients in the study group had either a history of cervical incompetence (9.6 vs. 0.9%, respectively, p  = 0.006) or cervical surgery (7.9 vs. 0%, respectively, p  = .003). Despite having shorter cervical length at recruitment (14.3 ± 5.9 vs. 16.9 ± 5.7, respectively, p  = .002) the rate of spontaneous delivery < 34-week gestation was lower in the study group (7.4 vs. 17.6%, respectively, p  = .036) and they delivered 1-week later compared to the control group (37.2 ± 2.1 vs. 36.2 ± 3.7, respectively, p  = 0.02). Conclusion: We found that for pregnant women with singletons and who had a short cervical length, the combined treatment of Arabin cervical pessary and vaginal progesterone had lower rate of preterm delivery < 34 weeks of gestation and prolonged gestation compared to those women who were treated with vaginal progesterone alone. Our preliminary findings warrant randomized control studies in order to further illuminate our results.

Objective: To investigate the rates of intrauterine adhesion following hysteroscopy for removal of RPOC associated with surgical termination of pregnancy., Methods: We conducted a retrospective cohort study of all cases of removal by hysteroscopy of RPOC associated with surgical termination of pregnancy carried out at the Yitzhak Shamir (Assaf Harofe) Medical Center from January 2013 to December 2018. The rates of postoperative intrauterine adhesion were assessed by follow-up hysteroscopy., Results: Our study involved 85 cases of removal by hysteroscopy of RPOC associated with surgical termination of pregnancy. The mean size of the RPOC was 1.9 ± 0.9 cm, and the mean time from termination of pregnancy to hysteroscopy was 1.5 ± 0.9 months. Two patients (2.4%) were readmitted for postoperative complications (fever). Postoperative follow-up information was available for 49 cases (57.6%). A total of 47 of these women had a normal uterine cavity (95.9%) while 2 women (4.1%) were diagnosed with mild intrauterine adhesions., Conclusions: Hysteroscopy for removal of RPOC following surgical termination of pregnancy is associated with low rates of postoperative intrauterine adhesions. Additional studies may determine whether this is the procedure of choice in these cases., (Copyright © 2020 The Society of Obstetricians and Gynaecologists of Canada/La Société des obstétriciens et gynécologues du Canada.

Purpose:  Conservative surgical management of adnexal torsion in pre- and post-menarchal girls by de-torsion and adnexal conservation is the current standard of care. The aim of this study is to investigate the long-term outcome of adnexal torsion in this population in terms of ultrasound appearance and ovarian volume., Methods:  Patients who were surgically treated for adnexal torsion and were < 18 years old at time of surgery were prospectively invited for ultrasound follow-up. The ultrasound exam included measurements of ovarian volume and grayscale appearance including identification of ovarian follicular activity., Results:  84 cases of torsion in this population were identified, and 37 of them were included in the study. Of those, the affected ovary could not be demonstrated on follow-up scan in six (16.2 %) cases. A difference of ≥ 2 cm 3 in ovarian volume between the affected and non-affected ovaries was diagnosed in 12 (32.4 %) cases, but follicular activity was observed in 10 of those. Thus, possible ovarian injury (including cases of non-demonstrated ovary and volume difference of ≥ 2 cm 3 between the affected and non-affected ovaries) was found in 18 (48.6 %) cases. Of the clinical and surgical parameters (including age at time of torsion, duration of pain prior to admission, cystectomy procedure and intraoperative "bluish" appearance of the ovary), only the presence of fever on admission was significantly associated with possible ovarian injury (p = 0.01)., Conclusion:  Long-term ultrasound follow-up of pre- and post-menarchal girls with a history of adnexal torsion may identify patients with adversely affected ovarian volume. The significance of this finding in terms of fertility is unknown., Competing Interests: The authors declare that they have no conflict of interest., (© Georg Thieme Verlag KG Stuttgart · New York.)

Purpose: Management of patients with placenta accreta spectrum (PAS) varies widely, and scarce data exist concerning its management. The current study compared two different surgical approaches in the management of PAS: the B-lynch approach (Group A) compared to the endovascular balloon catheters (Group B) Methods: A retrospective cohort study in two tertiary university-affiliated hospitals between the years 2004 and 2015. Elective cesarean section was planned at 35-37 weeks of gestation. One center utilized the B-lynch approach and the second utilized the endovascular balloon catheter approach. Results: The cesarean hysterectomy rate was significantly higher in the Group A approach compared to Group B (36.1 versus 29.2%, p  = .00). The number of packed cells units administered during and postoperatively were higher in the Group A compared with Group B ( p  = .006 and .043, respectively). Overall, surgery length and hospitalization duration were shorter in patients who underwent cesarean hysterectomy compared with those who underwent uterine preservation (B-lynch or endovascular balloon catheters) ( p  = .000 and p  = .004, respectively). Conclusions: The endovascular balloon technique seems to be a better option for uterine preservation due to less blood loss and higher postoperative hemoglobin level. Nevertheless, for those women who have completed their family planning, cesarean hysterectomy with the placenta left in situ is the safer and more suitable option.

Introduction: Preeclampsia (PE) is a major obstetric complication affecting 3-5% of pregnancies and a major contributor to fetal and maternal morbidity and mortality. The level of placental growth factor (PLGF) >150pg/ml in the third trimester was reported to predict PE occurrence within the next 14 days., Aims: We have conducted a preliminary study among pregnant Israeli women in order to evaluate whether maternal serum PLGF test at admission with suspected PE could rule-out the risk for developing PE., Methods: We prospectively enrolled pregnant women who were admitted to the high-risk pregnancy department at Shamir Medical Center with suspected PE. The women signed an informed consent form and blood samples were drawn, separated into serum, and taken for PLGF immuno-diagnostic test. All women with suspected PE were managed according to local protocol. The medical staff was blinded regarding PLGF results. All patients' computerized medical records, including developing of PE within 14 days and patients' computerized medical records were collected and a telephone interview was held to verify whether post charging events occurred., Results: Of the 29 women who were enrolled in the study, the group with PLGF<150 pg/ml included 19 women, who had mean PLGF=44.7pg/ml [(95%CI: 6.5-95.3], of which 14 developed PE (positive predictive value 73.7%). There were ten women in the PLGF>150pg/ml group, with mean PLGF=528.7 pg/ml [(95% CI:168-1300, P<0.001)] of which one developed PE (negative predictive value 90%). The sensitivity for ruling out PE by PLGF>150pg/ml was 93%, and the specificity=64.3., Conclusions: Incorporating blood testing of PLGF into the evaluation triage of pregnant women in Israel who admitted to the delivery clinic with suspected development of PE has generated high efficacy and negative predictive value (NPV) as was previously published Our findings are in accordance with results reported elsewhere but need validation in Israel with larger studies., Discussion: Assuming that at least 7% of ~184,450 (2018) live births in Israel are admitted to the high risk departments for evaluating suspected PE, implementing a PLGF test has a cost-benefit ratio of ~1/8.28 with a cost of NIS 2.52M for test performance of all women attending the delivery clinic with suspected PE over saving NIS 21.37M on unnecessary hospital days.

Introduction: Obstetrics Gynecology Department, "Shamir" ("Assaf Harofeh") Medical Center, Tzrifin There are 2 methods to perform amniocentesis in twin pregnancy. The widespread method is the two-punctures technique (1 for each sac). The other is a single uterine puncture through the intertwin membrane. No method is known to be superior. The main procedure-related complications are increased risk for fetal loss, amniotic fluid leakage and infection. The information regarding complications in twin pregnancy is limited and the method is not described., Objectives: To demonstrate whether a single uterine puncture is an acceptable alternative to the double uterine puncture method., Methods: A retrospective cohort study of 112 twin pregnancies which underwent amniocentesis by a single operator at "Shamir" ("Assaf Harofeh") Medical Center between the years 2010-2018. We compared a single uterine puncture (intervention group) to a double uterine puncture (control group)., Results: Eighty-six patients (76.7%) underwent a single uterine puncture and 26 (23.3%) underwent a double uterine puncture. Most pregnancies were uncomplicated in both groups (80.2% vs. 76.9% respectively); no statistical difference was seen in any complication. The most common complication was seeking medical help due to bleeding or contraction (12.8% in single puncture group vs 19.2% in double puncture group). PPROM, infection and loss of pregnancy were rare., Conclusions: Only a few studies have related to the method of amniocentesis and compared the results of these 2 methods. A single uterine puncture does not bear an increased risk of complications compared to the double puncture.

Study Objective: To investigate whether hysteroscopic features can contribute to the diagnosis of malignancy in endometrial polyps., Design: Retrospective review., Setting: Obstetrics and gynecology department., Patients: All women who underwent operative hysteroscopy for the removal of endometrial polyps between January 2012 and September 2017. Their medical records were reviewed, and information on medical, surgical, and obstetric history and hysteroscopic findings (including the number, size, and vascular appearance of the polyps) were abstracted., Interventions: Operative hysteroscopy with resection or biopsy of endometrial polyps., Measurements and Main Results: Five hundred fifty-six women were included in the study. Their mean age was 55.4 ± 12.4 years, and 322 (57.9%) were menopausal. Endometrial carcinoma was found in 26 (4.7%) cases, whereas endometrial hyperplasia was found in 5 (0.9%) cases. Endometrial carcinoma or hyperplasia was significantly associated with patients' age, menopausal status, increased polyp vascularity on hysteroscopy, and the presence of 3 or more polyps on hysteroscopy (p <.01 for all comparisons). However, the size of the largest polyp was not associated with endometrial carcinoma or hyperplasia. On logistic regression analysis, only increased polyp vascularity was associated with endometrial carcinoma or hyperplasia (odds ratio =13.5; 95% confidence interval, 5.6-32.3; p <.001). The sensitivity, specificity, positive predictive value, and negative predictive value of polyp vascularity for the diagnosis of polyps of nonbenign pathology were 51.6%, 94.3%, 34.8%, and 97.1%, respectively., Conclusion: Hysteroscopic findings of increased vascularity of endometrial polyps and numerous endometrial polyps may suggest the diagnosis of malignant polyps, in addition to demographic parameters such as age and menopausal status., (Copyright © 2019.

Purpose: In this study, we aimed to assess the distribution of genetic abnormalities leading to termination of pregnancy and its fluctuation during the past 8 years in light of those technical advances., Methods: Our cohort consisted of all pregnant women who underwent termination of pregnancy because of genetic aberrations in their fetuses from January 2010 through April 2018 in our medical center. The information that was gathered included: maternal age, results of the nuchal scan, results of the first- and second-trimester biochemical screening, ultrasonographic findings, reasons for conducting a genetic evaluation, gestational age at which termination of pregnancy was carried out, and the type of genetic aberration., Results: 816 women underwent termination of pregnancy at our institution due to genetic aberrations, most of them because of positive biochemical screening (n = 297, 36%) or because of maternal anxiety (n = 283, 35%). Findings in chromosomal microarray led to termination of pregnancy in 100 women (100/816, 12%). Chromosomal microarray had been performed due to maternal choice and not because of accepted medical indications among most of the women who underwent termination of pregnancy due to findings on chromosomal microarray (69/100, 69%)., Conclusion: Performing chromosomal microarray on a structurally normal fetus and identifying abnormal copy number variants may give the parents enough information for deciding on the further course of the pregnancy.

Importance: Infantile myofibromatosis (IM) is a benign neoplasm with a reported incidence of 1:150,000. The "solitary" type is characterized by a single lesion in the skin, muscle, or bone, whereas the "multicentric" type may also involve the viscera., Objective: This report describes the prenatal diagnosis of IM and recommendations for future pregnancy follow-up., Evidence Acquisition: This systematic search of the English literature yielded 8 reports documenting prenatal diagnosis of IM between 1999 and 2018., Results: Fetal age at diagnosis ranged from 13 to 38 weeks of gestation. Seven cases were diagnosed in the third trimester (30-34 weeks). Five cases were of the "solitary" type, and all successfully underwent surgical removal of the tumor with a good outcome. Three were of the "multicentric" type, and the 1 infant presenting with diffuse disease died several weeks after delivery., Conclusion and Relevance: The prenatal diagnosis of IM is often not made until the third trimester following a normal second-trimester anomaly scan, likely due to development of this lesion over time. Women should be referred for genetic counseling and consideration of preimplantation genetic diagnosis following the delivery of an affected child with the autosomal recessive form of the disorder and identified causative pathogenic variants.

Background: Complete hydatidiform mole and a co-existing normal fetus (CHMCF) is associated with a high complication rate. A possible association with assisted conception might increase the prevalence of CHMCF., Objectives: To study the potential association between assisted conception and the risks of CHMCF., Methods: Case series at a single university hospital from 2008 to 2018 are presented and contrasted with data from a comprehensive literature review (1998-2018). Cases were identified from the institutional database that matched the sonographic criteria for CHMCF. A literature review showed comparable cases., Results: None of the three pregnancies presented in this article resulted in a viable fetus, all were aborted. One of the three patients needed chemotherapy due to gestational trophoblastic neoplasia (GTN). A literature search identified 248 reported cases in which 22 fetuses (9%) reached term, 88/248 (35%) progressed to GTN, and 25/120 (21%) were conceived following assisted conception. From 2008 until 2018 at our medical facility, there were 3144 twin pregnancies of which 1667 (53%) were conceived using assisted conception. In our cohort, there was no statistical trend for assisted conception as an etiological factor for CHMCF., Conclusions: No association between assisted conception and the risk for CHMCF was established at our hospital, although approximately one-quarter of all reported CHMCF pregnancies are attributed to assisted conception technology. However, these data are not always reported, making it difficult to draw definitive conclusions.

Purpose: Retained products of conception (RPOC) may occur as the result of a morbidly adherent placenta. In these cases, the hysteroscopic removal of RPOC may be technically challenging, and may require more than one hysteroscopic procedure. We sought to compare the clinical, surgical, and postoperative characteristics of cases managed by either a one-step hysteroscopy procedure or a two-step hysteroscopy approach., Methods: A retrospective review of all RPOC cases managed by hysteroscopy from 1/2013 to 3/2018. We included cases of RPOC occurring following delivery and medical or surgical pregnancy terminations. The rates of postoperative intrauterine adhesions were assessed by office hysteroscopy., Results: A two-step procedure was required in 11 (3.9%) of the 358 women who underwent hysteroscopy for removal of RPOC during the study period. Comparison between the two-step and the one-step procedure groups revealed that the women in the two-step group were significantly older and the mean RPOC size was significantly larger (35.5 ± 4.1 years versus 30.7 ± 5.9 years, respectively, p = 0.01, and 38.6 ± 9.8 mm versus 22.3 ± 7.5 mm, p < 0.001, respectively). While the rates of intraoperative complications were similar between groups, readmission for postoperative fever was more common in the two-step group (18.2% versus 2.0%, respectively, p = 0.03). Postoperative intrauterine adhesions were diagnosed in 20.0% and 5.2%, respectively (p = 0.05)., Conclusions: The two-step hysteroscopic approach enabled the complete removal of larger RPOC masses without the use of uterine curettage. The women who underwent the two-step procedure, however, were at increased risk for postoperative fever and postoperative intrauterine adhesions.

Objectives: Vasa previa (VP) is a congenital placentation disorder in which fetal vessels run across the internal os of the cervix under the fetal presentation. This rare condition is associated with a high rate of perinatal morbidity and mortality when undetected before delivery. Roughly 85% of all cases of VP can be associated with one or more identifiable risk factors including in-vitro fertilization (IVF), multiple gestations, bilobed, succenturiate or low-lying placentas, and velamentous cord insertion (VCI). Recent evidence indicates the need for standardized prenatal targeted scanning protocols of pregnancies at risk of VP. The present study reports on pregnancies that began with multiple gestations but ended with a single fetus diagnosed with VP., Study Design: We retrospectively collected and reviewed medical records from 2006 to 2018 of early multiple pregnancies that ended with a single fetus diagnosed with VP in our medical center, including three cases of twin gestation complicated by a vanishing twin and a case of multifetal reduction in triplet pregnancy. This retrospective cohort study was approved by our Institutional Clinical Research Committee., Results: The database search identified 50 pregnancies that started as multiple gestations but continued as singletons. Of these, 4 pregnancies were diagnosed with VP, for a prevalence of 8.0%. For two of the four cases, the diagnosis was made during delivery as expressed by a low Apgar score at 1 and 5 min, a low cord blood pH value, newborn resuscitation, blood product transfusion, and NICU supervision. There was a statistically significant difference in the prevalence of VP in pregnancies that started as multiple gestations but continued later as singletons compared to multiple pregnancies (8.0% vs. 0.2% respectively, p < 0.0001). The OR for VP in pregnancies that started as multiple gestations but continued as singletons was 41.1 (95% CI, 12.77-131.94)., Conclusions: Our findings suggest there is an increased risk of VP in conceptions that started as viable multiple gestations but continued later as singletons. If our findings supported by others, it may be prudent to consider all twins at the beginning of pregnancy to be at risk for VP, irrespective of the actual number of life fetuses at later stages of gestation., (Copyright © 2019 Elsevier B.V.
