Medical treatment for early pregnancy loss following in vitro fertilization compared to spontaneous pregnancies.

BACKGROUND: Misoprostol is a well-studied medical treatment for early pregnancy loss (EPL), with success rates ranging between 70 and 90%. However, treatment failure is associated with major patient discomfort, including the need for surgical intervention to evacuate the uterus. It was previously reported that medical treatment was especially successful among women who conceived after in vitro fertilization (IVF). We aimed to study if there is a difference in rates of medical treatment failures for EPL between pregnancies conceived by IVF and spontaneous pregnancies. METHODS: In this retrospective cohort study, we included all women who underwent medical treatment for EPL at our institute between 07/2015 and 12/2020. Treatment outcome was compared between IVF and spontaneous pregnancies. Treatment failure was defined as a need for surgical intervention, namely, dilation & curettage (D&C) and/or hysteroscopy, due to retained products of conception, which was defined as a gestational sac or endometrial thickness greater than 15 mm in a TVS scan. RESULTS: Overall, 775 patients were included, of which 195 (169/775 = 25.1%) ultimately required surgical intervention. There was no difference between the study groups in the rate of treatment failure. However, among IVF pregnancies, the rate of emergency D&C was lower (3.6% vs. 9.8%, p = 0.001), compared to spontaneous group. CONCLUSION: In cases of medical treatment for EPL, IVF pregnancies had no differences in rates of treatment failure compared to spontaneous pregnancies. That being said, IVF pregnancies have lower chances to undergo emergency D&C, compared to spontaneous pregnancies.

Failure Rate of Medical Treatment for Miscarriage Correlated with the Difference between Gestational Age According to Last Menstrual Period and Gestational Size Calculated via Ultrasound.

Objective: To study whether the interval between gestational age calculated using the last menstrual period (GA-LMP) and gestational age calculated via ultrasound (GA-US) is correlated with the success rate of medical treatment in cases of miscarriages. Methods: This was a retrospective cohort study conducted in a gynecology unit in a tertiary medical center. Women who underwent medical treatment with Misoprostol for miscarriage at the Edith Wolfson Medical Center between 07/2015 and 12/2020 were included. Incomplete or septic miscarriages, multiple pregnancies, patients with irregular periods, and cases of missing data were excluded. Failure of medical treatment was defined as the need for surgical intervention due to a retained gestational sac, severe bleeding or retained products of conception. The cohort study was divided into two groups: patients with successful treatment and patients for whom surgical intervention was eventually needed. We performed both a univariate and multivariate analysis in order to identify whether a correlation between GA-LMP and GA-US interval is indeed a factor in the success rate of a medical abortion. Results: Overall, 778 patients were included in the study. From this cohort 582 (74.9%) had undergone a successful medical treatment, while 196 (25.1%) required surgical intervention due to the failure of medical treatment, as defined above. The GA-LMP to GA-US interval (in weeks) was 2.6 ± 1.4 in the success group, while the GA in the failure group was 3.1 ± 1.6 (p < 0.001). After performing a multivariant regression analysis, we were able to show that the GA-LMP to GA-US interval was found to be independently correlated with an increase in the treatment failure rate (aOR = 1.24, CI 95% (1.01-1.51), p = 0.03). Conclusions: In cases of miscarriage, longer GA-LMP to GA-US interval has been shown to be an independently correlated factor to lower success rate of the medical treatment option.

Long-term development of surgical outcome of laparoscopic sacrohysteropexy with anterior and posterior mesh extension.

INTRODUCTION AND HYPOTHESIS: Long-term durability and functional outcome of laparoscopic sacrohysteropexy (LSH) remains to be confirmed. We set out to assess the development of surgical outcome in women with increasing minimal follow-up. METHODS: All women after LSH with anterior and posterior mesh extension operated for advanced apical uterine prolapse at Geoffroy Saint-Hilaire clinic from July 2005 to June 2020 were enrolled in this retrospective study. Last known follow-up information was used for the analysis and allocation into groups. The surgical success was defined as no prolapse beyond hymen, no symptomatic recurrence or no retreatment. Functional outcome was evaluated from validated questionnaires and presence of pelvic floor disorders. The outcomes were compared with preoperative state using chi-square and Fisher's test; p < 0.05 was considered significant. RESULTS: In total, 270 patients after LSH with a follow-up of up to 14.5 years were enrolled and divided into groups according to their last follow-up length: ≥ 1 year 242, ≥ 3 years 112, ≥ 5 years 76, ≥ 7 years 45 and ≥ 10 years 18 women. Increase of minimal follow-up was associated with gradual decrease in surgical success. Rates of stress urinary incontinence were unchanged by the surgery, while anal incontinence and constipation rates decreased significantly; 14.5% of women were operated on for SUI in the follow-up. The PFDI-20, PFIQ-7 and VAS bother scores decreased significantly regardless of minimal follow-up length. CONCLUSIONS: LSH with anterior and posterior mesh extension is a safe, effective and durable surgery with a positive long-term effect on quality of life. Although the surgical success gradually decreases, LSH remains a surgical success in most women.

Outcomes of sacrocolpopexy/sacrohysteropexy with mesh placement targeted to affected compartment.

OBJECTIVE: No recommendation regarding the number of meshes to be implanted in laparoscopic genital prolapse surgery exists. Is it necessary to implant a mesh into a compartment that is not affected to prevent its prolapse in the follow-up? Our objective was to compare the long-term outcomes of laparoscopic sacrocolpopexy according to compartments where mesh was implanted. STUDY DESIGN: This is a retrospective cohort study of 328 patients after laparoscopic sacrocolpopexy at our centre in 7/2005 - 3/2021. 294 patients with perioperative data and POP-Q and/or prolapse symptoms in mean follow-up of 42.8 months was available for the outcome analysis. Surgical failure was defined as prolapse beyond hymen, subjective recurrence or retreatment. The women were divided into four groups depending on compartments, where the mesh was implanted. Group A - anterior, group P - posterior, Group AP - compound of patients with anterior or posterior single arm mesh placement and (B), with anterior and posterior arm placement. Groups AP and B were compared for feasibility of single compartment mesh implantation. Comparison of groups A and P allowed assessment of non-inferiority of single anterior vs. posterior compartment placement. The data were compared using Wilcoxon Two Sample test, Chi-square test or Fishers Exact test, p-value < 0.05 was considered statistically significant. RESULTS: A single compartment mesh implantation was associated with shorter operating time and hospital stay and comparable incidence of complications. A statistically significant difference in all POP-Q points in favour of group B was observed, however, with comparable rate of prolapse beyond hymen(6.3%AP vs. 7.8%B). Similar frequency of surgical failure (17.5%AP vs. 13.8%B) and incidence of de novo pelvic floor disorders or pain was observed. Comparison of groups A and P showed higher suspension of point C in group P(-2.6 vs. -4.0, p < 0.05) with no difference in points Ba, Bp, surgical failure rate and de novo pelvic floor disorders. CONCLUSION: Implantation of a single sheet of mesh was not associated with inferior outcome to implantation of mesh to both compartments. Laparoscopic sacrocolpopexy with a single mesh arm placed into the affected compartment along with apical suspension does not induce a de novo prolapse in unoperated compartment.

Effect of Age on Complications Rate and Surgical Outcomes in Women Undergoing Laparoscopic Sacrohysteropexy and Sacrocolpopexy.

STUDY OBJECTIVE: To compare perioperative and long-term outcomes of laparoscopic sacrohysteropexy/sacrocolpopexy in different groups of age. DESIGN: This was a retrospective cohort study. Patients were evaluated preoperatively and postoperatively (starting from 1 month after surgery and then annually). SETTING: The department of functional pelvic surgery and oncology, a tertiary care center. PATIENTS: All patients who underwent laparoscopic sacrohysteropexy/sacrocolpopexy, between July 2005 and December 2019. INTERVENTIONS: Laparoscopic sacrohysteropexy/sacrocolpopexy. MEASUREMENTS AND MAIN RESULTS: The study population was divided into 3 groups, according to age at the time of surgery: group 1, <65 years; group 2, between 65 and 75 years, and group 3, >75 years. The primary outcome was the rate of perioperative complications. The secondary outcome was the comparison of long-term results among the groups. A total of 330 patients were included: in group 1, 183 patients (mean age 53.4 ± 8.2), in group 2, 92 patients (mean age 69.2 ± 2.9), and in group 3, 55 patients (mean age 79.3 ± 3.5). The overall perioperative complications rate (up to 30 days after surgery) was 5.7%. No differences among the groups in operative details and rates of perioperative complications were observed. During the follow-up period, 37 patients (11.2%) presented with prolapse recurrence (objective and/or subjective); the rates of prolapse recurrence and long-term complications were similar among the groups. Similarly, the groups did not differ in postoperative functional results except for postoperative stress urinary incontinence. A surgery for stress urinary incontinence was more common among patients in group 3 (group 1, 13.4%; group 2, 11.9%; group 3, 31.3%; p = .008). CONCLUSION: Laparoscopic sacrohysteropexy/sacrocolpopexy is associated with low rates of perioperative and long-term complications. We did not find a difference in rates of complications and/or long-term outcomes, between different age groups.

Placental abnormalities differ in small for gestational age neonates in relation to their prenatal sonographic abdominal circumference measurements.

BACKGROUND: Antenatal detection of abdominal circumference (AC) <10th percentile, among small for gestational age (SGA) neonates, probably reflects the severity of their growth restriction. We aimed to study neonatal outcome and placental pathology among SGA neonates in correlation to their AC measurements. METHODS: Maternal and neonatal computerized medical records and placental histopathology reports of all SGA neonates, (neonatal birth-weight ≤10th percentile), born between 24 and 42 weeks, during 2015-2018 were reviewed. Included cases with fetal biometric measurements conducted up to 7 days prior labor. Results were compared between cases with sonographic antenatal AC <10th percentile and neonates with sonographic antenatal AC ≥10th percentile. Placental lesions were classified according to "Amsterdam" Placental workshop criteria. RESULTS: The AC <10th percentile group (n = 148) was characterized by higher rate of nulliparity (p = .003), and induction of labor (p = .009), as compared to the AC ≥10th percentile group (n = 41). There were no between groups differences in the rate of maternal BMI (kg/m2), hypertensive disorders, diabetes or smoking. Neonatal hypoglycemia was more common in the AC <10th percentile group as compared to the AC ≥10th percentile group (p = .04). Placentas from the AC <10th percentile group were smaller (p < .001), with more MVM lesions (p = .02) and chronic villitis (p = .04). By multivariate regression analysis, AC <10th percentile and maternal hypertensive disorders, were found to be independently associated with placental MVM lesions, aOR = 2.43 (95% CI 1.04, 5.88) and aOR = 3.15 (95% CI 1.06, 9.31), respectively. CONCLUSIONS: Higher rate of placental maternal malperfusion lesions, chronic villitis, and more neonatal hypoglycemia characterize SGA neonates with AC <10th percentile, pointing to the importance of AC measurement as an indicator for placental insufficiency.

Long term outcomes of laparoscopic sacro/colpo-hysteropexy with and without rectopexy for the treatment of prolapse.

INTRODUCTION AND HYPOTHESIS: Laparoscopic sacrohysteropexy (LSH), sacrocolpopexy (LSC) and ventral rectopexy (LVR) with mesh are advocated for surgical treatment of pelvic and rectal prolapse. Our study aims at showing the feasibility of concomitant laparoscopic prolapse repair by comparing perioperative and long-term outcomes of LSH or LSC with and without LVR. METHODS: This is a retrospective study carried out on 348 women operated on between July 2009 and July 2019. Patients were divided into four groups: (1) LSH only, (2) LSC only, (3) LSH + LVR and (4) LSC + LVR. POP-Q scores and satisfaction questionnaires were recorded at baseline and then annually. Outcomes were defined as subjective failure (vaginal/rectal prolapse symptoms), objective failure (prolapse to/beyond the hymen, full thickness rectal prolapse) or retreatment for prolapse. Complications were collected and graded according to the Clavien-Dindo classification. RESULTS: Three hundred forty-eight women underwent laparoscopic repair for pelvic and rectal prolapse (219, 44, 66 and 19 in group 1, 2, 3 and 4, respectively). Median follow-up was 24 (4-174) months. Success rate for both rectal and pelvic prolapse was 90.2%. Recurrence rates were not significantly different between the groups (12.3%, 6.8%, 9.1% and 10.5% for groups 1, 2, 3 and 4, respectively). Significant improvement was noticed in satisfaction questionnaires in all groups. There was no difference in perioperative and late complications. CONCLUSION: The combined laparoscopic procedure appears to be safe and efficient in treating pelvic and rectal prolapse. Appropriate patient selection and available surgical expertise should determine whether to perform these procedures combined or separately.

The effect of preemptive local anesthesia on postoperative pain following vaginal hysterectomy: A randomized controlled trial.

OBJECTIVE: We aimed to study the effect of preemptive local anesthetic without adrenaline on postoperative pain following vaginal hysterectomy and concomitant trans obturator tape (TOT). STUDY DESIGN: This was a double-blinded, randomized, controlled trial. Women who undergone elective vaginal hysterectomy were included. Solutions of either Bupivacaine-Hydrochloride 0.5%, or Sodium-Chloride 0.9% as a placebo, were prepared prior to surgery, according to randomization. The chosen solution was injected before incision, in a circumferential manner, to the cervix. The amount of fluid administered was 10 ml. When colporrhaphy was also performed, an additional 5 ml of solution were injected in the midline of the vaginal wall prior to each incision line. We conformed to the CONSORT recommendations. By utilizing the 10 cm Visual-analogue-scale (VAS) we assessed post-operative pain at rest at 3, 8, and 24 h, and during ambulation at 8 and 24 h. We estimated that the intervention would cause a 25% reduction in the primary outcome. The required total sample size was calculated to be 30 patients women for each group. We used ANOVA for continuous variables and the Chi-square or Fisher exact tests for categorical variables. RESULTS: A total of 30 women were included in each group. The level of postoperative pain, as assessed by VAS, was not significantly different between the groups, in all points of time. In addition, there was no difference between the groups in opioid based analgesics during recovery, nor in postoperative analgesic use. CONCLUSION: Preemptive local anesthesia was not shown to be efficient in reducing postoperative pain after vaginal hysterectomy and TOT.

Anatomic Asymmetry in Sentinel Lymph Node Detection in Endometrial Cancer.

STUDY OBJECTIVE: To determine whether the concomitant use of indocyanine green (ICG) with technetium-99m-filtered sulfur colloid (Tc99m-FSC) improves bilateral sentinel lymph node (SLN) detection rate in endometrial cancer and whether anatomic concordance of pelvic lymph nodes exists and can be used to predict SLN location in cases of unilateral mapping failure. DESIGN: Retrospective cohort study. SETTING: Tertiary academic medical center in Holon, Israel. PATIENTS: Patients diagnosed with endometrial cancer, who underwent SLN mapping with Tc99m-FSC, ICG, or both, at our center between 2014 and 2019. INTERVENTIONS: A total of 111 patients were included in the study. SLN mapping using Tc99m-FSC was performed in 101 (91.9%) patients, and ICG injection was given to 64 (57.6%) patients of whom 55 (49.5%) received both. We compared SLN detection rates (unilateral and bilateral) and anatomic symmetry for each method alone and for a combination of the 2. MEASUREMENTS AND MAIN RESULTS: The overall detection rate for unilateral SLNs was 96.4%; 96.9% with ICG, 93.1% with gamma-probe, and 98.2% by combining both methods. The total bilateral detection rate was 72.1%, with ICG performing better as a single tracer than Tc99m-FSC (75% vs 63.4%, respectively). In 55 women in whom both tracers were used, the bilateral detection rate was significantly higher compared with Tc99m-FSC alone. Symmetric pelvic anatomic concordance of SLN was found in only 35 of 80 patients with bilateral SLN detection (43.8%). CONCLUSION: The combination of preoperative radioisotope injection and intraoperative ICG administration may yield the best bilateral SLN detection rate. In cases of unilateral mapping failure, one cannot rely on the anatomic location of the ipsilateral SLN detected to harvest the complementary node because the symmetric concordance is poor.

[PUSTULAR PSORIASIS DURING PREGNANCY: WHEN IS THE RIGHT TIME TO DELIVER?]

INTRODUCTION: General pustular pruritus psoriasis (GPPP), also known by the name impetigo herpetiformis, is a rare type of pustular dermatosis which typically occurs in pregnant women during the 3rd trimester and usually regresses after birth. The disease is characterized by acute abruption of erythematous plaque with a disseminated spread of sterile pustule, and may progress to sepsis and even death. Notably, it also carries obstetric complications and is associated with an increase in neonatal morbidity and stillbirth. We present a case report of a patient, and discuss the importance of proper management in this rare condition.

The association between the number of vaginal examinations during labor and perineal trauma: a retrospective cohort study.

PURPOSE: To study the association between the number of vaginal examinations (VEs) performed during labor and subsequent severe perineal trauma. METHODS: This is a retrospective cohort study. We included all women admitted to the delivery ward between 2008 and 2017, in active labor. Exclusion criteria included preterm deliveries (< 37 weeks), Cesarean deliveries and episiotomy during delivery. The primary outcome, severe perineal trauma, was defined as perineal tears grades 3-4. The cohort was divided into 4 groups, based on the number of VEs performed during labor: Group 1-up to two VEs (n = 4588), Group 2-three to four VEs (n = 5815), Group 3-five to six VEs (n = 4687), and Group 4-seven or more VEs (n = 7297). RESULTS: Overall, 22,387 women were included in the study. The rate of severe perineal trauma in groups 1, 2, 3 and 4 was 0.4%, 0.1%, 0.8%, and 0.4%, respectively (p < 0.001). Performing five or more VEs during labor was associated with a higher risk of severe perineal trauma (0.26% vs. 0.53%, p < 0.01), as compared to four VEs or less. Using a logistic regression model, we found that performing five or more VEs during labor (aOR = 1.72 CI 95% (1.21-2.47), p < 0.001) or performing an instrumental delivery (aOR = 2.65 CI 95% (1.72-4.07), p < 0.001) were directly associated with the risk for severe perineal trauma. Applying epidural anesthesia showed an inverse association with severe perineal trauma (aOR = 0.54 CI 95% (0.38-0.77), p < 0.001). CONCLUSION: Performing five or more VEs during active labor is associated with an increased risk for severe perineal trauma.

Laparoscopic management of pelvic organ prolapse recurrence after open sacrocervicopexy.

In this narrated video we present a case of pelvic organ prolapse (POP) recurrence 12 years after sacrocervicopexy, outline our management and suggest an optimal laparoscopic surgical technique that may reduce the risk of future recurrence. A 71-year-old patient, who had undergone an open sub-total hysterectomy with sacrocervicopexy 12 years previously, complained of a bulging sensation in her vagina, of 12 months' duration. On physical examination, a Pelvic Organ Prolapse Quantification (POP-Q) stage III prolapse was diagnosed, with marked apical, anterior and posterior compartment prolapse. On laparoscopy we identified the old mesh attached to the promontory and to the vaginal apex, without any fixation of the vaginal walls. Complete mesh excision was performed, followed by vaginal dissection to facilitate implantation of two new meshes and performing a new sacrocolpopexy. No postoperative complications occurred. Over 6 weeks of post-operative follow-up, there was no pelvic pain, dysuria or dyschezia. A good anatomical result was noted without any prolapse. Laparoscopy appears to be an effective approach to complete mesh excision. For the treatment of prolapse recurrence, complete excision of the old mesh with new pelvic mesh-augmented reconstruction is recommended. Thorough dissection of the vesico-vaginal and recto-vaginal spaces followed by mesh fixation to the relevant vaginal walls may reduce recurrence.

None, One, or Both Placentas Involved with Malperfusion Lesions in Twin Pregnancies Complicated by Preeclampsia-Does It Matter?

We aimed to study the association between the number of placentas with vascular malperfusion lesions in dichorionic twin pregnancies complicated by preeclampsia and the severity of the disease and pregnancy outcomes. Dichorionic twin pregnancies with preeclampsia (n = 125), from January 2007-June 2018, were reviewed. Affected placenta was defined as the presence of maternal/fetal vascular malperfusion lesions. Maternal demographics, pregnancy characteristics, and neonatal outcomes were compared between three groups: no pathological placentas, one pathological placenta, and two pathological placentas. Composite adverse neonatal outcome was defined as ≥ 1 early neonatal complication. Regression analysis models were used to recognize independent associations with the number of involved placentas. The two pathological placenta group (n = 57 pregnancies), the one pathological placenta group (n = 40 pregnancies), and the no pathological placenta group (n = 28 pregnancies) differed in terms of gestational age (GA) at delivery (p < 0.001, p = 0.008) and the rates of severe features (p = 0.028, p = 0.047). Neonates born to the two pathological placenta group (n = 114), the one pathological placenta group (n = 80), and the no pathological placenta group (n = 56) were characterized by lower birth weights (p < 0.001, p = 0.031), higher rates of small for gestational age (SGA) (p = 0.017, p = 0.748), neonatal intensive care unit admission (p = 0.004, p = 0.013), and composite adverse neonatal outcome (p < 0.001, p = 0.025). By regression analyses, the presence of two pathological placentas was found to be independently associated with severe features (aOR = 5.1), GA at delivery < 32 weeks (aOR = 2.0), SGA (aOR = 2.5), and composite adverse neonatal outcome (aOR = 2.7). In dichorionic twin pregnancies, there is an association between the presences of placental vascular malperfusion lesions in none, one, or both placentas and the development of early and severe preeclampsia, as well as with SGA and adverse neonatal outcome.

The association between isolated oligohydramnios at term and placental pathology in correlation with pregnancy outcomes.

INTRODUCTION: Isolated term oligohydramnios (ITO) is an obstetrical complication of which the etiology, management, and clinical importance are controversial. In attempt to deepen our understanding, we aimed to study placental pathology and pregnancy outcomes in pregnancies complicated by ITO. MATERIALS AND METHODS: - Maternal demographics, neonatal outcomes, and placental histopathology reports of all pregnancies complicated by ITO at 370/7 to 410/7 weeks were reviewed. Excluded were cases complicated by hypertensive disorders, intrauterine fetal growth restriction, placental abruption, and deliveries of undiagnosed small for gestational age neonates. Results were compared between the ITO group and a control group matched for gestational age and mode of delivery. Placental lesions were classified according to the current "Amsterdam" criteria. Composite adverse neonatal outcome was defined as one or more of the following early complications: neonatal intensive care unit admission, sepsis, blood transfusion, phototherapy, respiratory morbidity, cerebral morbidity, necrotizing enterocolitis, or death. RESULTS: The study group included 108 patients with ITO that were compared to matched controls. Placentas from the ITO group were characterized by higher rates of placental weights <10th centile (p < 0.001), abnormal cord insertion (p < 0.001), and maternal vascular malperfusion (MVM) lesions (p < 0.001). Neonates from the ITO group had lower birth weights (p < 0.002), and worse composite adverse neonatal outcome (p = 0.028) compared to controls. CONCLUSION: - The current study demonstrates higher rates of placental MVM lesions, and worse neonatal outcome in pregnancies complicated by ITO. These novel findings suggest that ITO should be seen as part of the "placental insufficiency" spectrum.

Rectal injury during laparoscopic mesh removal after sacrocervicopexy.

In this video we present a case of rectal injury, which occurred during laparoscopic mesh removal following sacrocervicopexy. Four years after sub-total hysterectomy with laparoscopic sacrocervicopexy, a 64-year-old patient still suffered from intense proctalgia and pain while sitting. On physical examination, intense pain could be triggered by palpating the left aspect of the levator ani muscle, raising the suspicion of an association with the mesh and leading to the decision for its removal. The left posterior arm of the mesh was removed completely laparoscopically. During this procedure, a rectal lesion was diagnosed and immediately repaired by a double layer of interrupted sutures. There was an immediate and complete resolution of the symptoms after surgery, with no short-term prolapse recurrence or postoperative complications. Laparoscopy appears to be an efficient approach to mesh excision. A high level of alertness to recognize intraoperative injuries is warranted.

The association between abnormal coagulation testing in preeclampsia, adverse pregnancy outcomes, and placental histopathology.

Objective: We aimed to determine whether abnormal coagulation laboratory testing results in preeclampsia, are associated with adverse pregnancy outcomes and placental histopathology lesions. Methods: Demographic, labor, laboratory-testing, and placental histopathology reports of pregnancies complicated by preeclampsia were compared between those with and without abnormal coagulation profile (ACP). Results: Of 348 cases of preeclampsia 16.1% had ACP. There were no differences between the groups in GA at delivery, severe features, placental-abruption, SGA, composite adverse neonatal outcome and placental histopathology lesions. Conclusion: ACP in pregnancies complicated by preeclampsia was not associated with any of the studied outcomes. Our data question the usefulness of routine coagulation tests in the initial assessment of women presenting with preeclampsia.

Pregnancy outcomes in correlation with placental histopathology in subsequent pregnancies complicated by fetal growth restriction.

OBJECTIVE: In attempt to shed new light on the etiopathogenesis of fetal growth restriction (FGR) we aimed to compare pregnancy outcomes and placental histopathology in cases of first vs. subsequent FGR occurrence. STUDY DESIGN: Pregnancy and placental reports of FGR pregnancies (defined by birth weight <10th percentile), born between 2008 and 2018 were reviewed. Included only cases with recurrent FGR, in two consecutive pregnancies, thus each subject served as her own control in two FGRs consecutive pregnancies. Neonatal outcome and placental histopathology were compared between the first FGR delivery (first FGR group) and the subsequent FGR delivery (subsequent FGR group). Composite adverse neonatal outcome was defined as one or more early neonatal complications. RESULTS: Included in the study a total of 96 cases with recurrence of FGR pregnancies. Placentas from the first FGR group were characterized by higher rate of maternal vascular malperfusion (MVM) lesions as compared with the subsequent FGR group (71.8% versus 55.2%, respectively, p = 0 .02). Adverse neonatal outcome was more prevalent in the first FGR group as compared to the recurrent FGR group (41.6% versus 25%, respectively, p = 0.02). After controlling for confounders, using multivariate regression analysis, placental MVM lesions (aOR = 1.36, 95% CI = 1.12-1.45) and composite adverse neonatal outcome (aOR = 1.18 95% CI = 1.09-1.55) were found to be independently associated with the first FGR group. CONCLUSION: First event of FGR is associated with a higher rate of placental MVM lesions and adverse neonatal outcome as compared to FGR in subsequent pregnancies.

Placental histopathological lesions in correlation with neonatal outcome in preeclampsia with and without severe features.

OBJECTIVE: We aimed to compare pregnancy outcome and placental histopathology in women with preeclampsia (PE) with and without severe features. METHODS: The medical records and placental pathology reports of all pregnancies complicated by PE during 2008-2016, were reviewed. Results were compared between those with and without severe features (severe PE vs. mild PE groups), according to current ACOG guidelines. Placental lesions were classified to maternal/fetal vascular supply lesions, and maternal/fetal inflammatory responses. Small for gestational age (SGA) was defined as neonatal birth-weight ≤10th%. Composite adverse neonatal outcome was defined as one or more of the following: sepsis, transfusion, phototherapy, respiratory morbidity, cerebral morbidity, NEC, or death. RESULTS: The severe PE group (n = 284) was characterized by lower gestational age at delivery (p < 0.001), and higher rates of antenatal corticosteroid use (p = 0.003), and cesarean deliveries (p < 0.001) as compared to the mild PE group (n = 151). More placentas <10th% and more composite maternal vascular malperfusion (MVM) lesions were observed in the severe PE group as compared to the mild PE group (p < 0.001 for both). In multivariate analysis, composite placental MVM lesions were independently associated with severe PE (aOR = 1.75, 95%CI 1.4-4.9). Higher rates of SGA (p = 0.016), and composite adverse neonatal outcome (p = 0.002) characterized the severe PE group. In multivariate analysis, adverse neonatal outcome was independently associated with gestational age (aOR = 0.54, 95%CI 0.49-0.68), SGA (aOR = 1.75, 95%CI = 1.15-3.59), severe PE (aOR = 1.8, 95%CI = 1.13-3.54) and placental MVM lesions (aOR = 2.13, 95%CI = 1.05-4.39). CONCLUSION: More pronounced placental pathology and higher rate of adverse neonatal outcome characterize preeclampsia with severe features as compared with the milder form of the disease.

Placental Component and Pregnancy Outcome in Singleton versus Twin Pregnancies Complicated by Preeclampsia.

OBJECTIVE: To compare placental histopathological lesions and pregnancy outcomes in singleton and twin pregnancies complicated by preeclampsia (PE). METHODS: Maternal characteristics, neonatal outcomes, and placental histopathology reports of pregnancies complicated by PE between January 2008 and October 2016 were reviewed. Results were compared between singletons (singleton group) and dichorionic-diamniotic twins (twin group). Placental lesions were classified into maternal and fetal vascular supply lesions. Small for gestational age (SGA) was defined as birth weight ≤10th percentile. Composite adverse neonatal outcome was defined as one or more early neonatal complications. RESULTS: Compared to the twin group (n = 67), the singleton group (n = 275) was characterized by lower maternal age (p = 0.003), higher gestational age (p < 0.001), higher rates of previous PE (p = 0.017), chronic hypertension (p = 0.036), and severe features (p < 0.001). Placentas from the singleton group were characterized by higher rates of maternal vascular malperfusion lesions (p < 0.001) and fetal vascular supply lesions (p = 0.002). Using multivariable regression analysis, composite maternal and fetal vascular malperfusion lesions were independently associated with singletons (aOR = 2.7, 95% CI = 1.2-7.8, p < 0.001, and aOR = 1.2, 95% CI = 1.2-5.6, p = 0.025, respectively). SGA was more common in the singleton group (p = 0.002). Neonatal outcome did not differ between the groups. CONCLUSION: Placentas from singleton pregnancies complicated by PE were characterized by higher rates of maternal and fetal vascular lesions compared to those from twin pregnancies, suggesting that different mechanisms participate in the development of PE in these two groups.
