Objective: To assess the risk of adverse pregnancy outcomes in subsequent pregnancies among women treated with methotrexate for ectopic pregnancy., Methods: In a retrospective single-center study, data were assessed for women treated with methotrexate for ectopic pregnancy at Asaf Harofe Medical Center, Zerifin, Israel, between May 2004 and May 2014., Results: Overall, 226 women were treated with methotrexate for ectopic pregnancy and subsequently conceived. The median time from treatment to conception was 10 months (range 1-120 months), and 127 women conceived within 12 months of treatment. Except for early missed abortion-which affected 23 (10.2%) pregnancies-adverse pregnancy outcomes such as fetal malformations were rare. The frequency of early abortion was lowest for women who conceived within 6 months of treatment with methotrexate (3/93, 3.2%), increased between 6 and 23 months (15/83, 18.1%), and remained high thereafter (7/50, 14.0%; P=0.006)., Conclusion: The frequency of fetal malformation in a subsequent pregnancy was low among women treated with methotrexate for ectopic pregnancy. The frequency of early missed abortion was lowest during the first 6 months after treatment with methotrexate., (© 2017 International Federation of Gynecology and Obstetrics.)

Objective: The article aimed to assess the spectrum of fetal renal tract abnormalities as a major finding leading to termination of pregnancy (TOP)., Method: The study population included all pregnant women with singleton pregnancy who underwent TOP in our institute because of fetal renal tract indications between 1998 and 2015. We specifically excluded TOPs performed because of multiple pregnancies, multisystem defects, abnormal karyotype and chromosomal or genetic defect not related to renal tract abnormalities. The patients were stratified into late TOP (≥24 weeks' gestation) and early TOP (<24 weeks' gestation)., Results: There were 97 (3.5%) cases of TOP because of fetal renal abnormalities and are the subjects of this study. Of these cases, 19 (19.6%) were at ≥24 weeks' gestation. Renal cystic disease was the leading indication for late TOP compared with early TOP group (31.8% vs 21.8%, respectively, p = 0.001). Routine prenatal care raised suspicion of abnormalities in 11 (50.9%) cases, and diagnosis was established by additional tests. Abnormal findings were either missed in one (5.3%) case or developed later in two (10.5%) cases. No routine prenatal screening was performed in the remaining five (26.3%) cases., Conclusions: We found a different distribution for fetal renal tract abnormalities leading to late versus early TOP. As many of renal tract malformations could have been diagnosed earlier (~32%), timely scanning may reduce the need for late TOPs in some cases. © 2016 John Wiley & Sons, Ltd., (© 2016 John Wiley & Sons, Ltd.)

Objective: The objective of this study was to compare the associations of crown-rump length (CRL) discrepancy with birthweight discordance in spontaneous versus in vitro fertilization (IVF) monochorionic (MC) twin pregnancies., Method: This is a multicenter retrospective study on women with twin pregnancies assessed for nuchal translucency between January 1997 and July 2013. The study group was subdivided into MC twins conceived spontaneously and after IVF. Pregnancies with later fetal death or twin transfusion syndrome were excluded. A large-weight discordance was defined as a difference of birthweights of >15%., Results: The study group included 171 pregnancies; of them, 142 (83%) were spontaneous and 29 (17%) were IVF conceived. In the entire cohort, we found a significant correlation between birthweight discordance and CRL discrepancy (r = 0.173, P < 0.05). While a significant correlation was found between CRL discrepancy and birthweight discordance in spontaneous-conceived pregnancies (n = 142, r = 0.24, P = 0.005), such correlation was not present in IVF pregnancies (n = 29, r = -0.7, P = 0.724). A logistic regression analysis found significant odds of larger-weight discordance for each increase of 1% in CRL discrepancy among spontaneously conceived pregnancies (odds ratio = 1.1, confidence interval = 1.03-1.2, P = 0.005). A receiver operating characteristic (ROC) for large-weight discordance in the spontaneously conceived pregnancies demonstrated an area under the ROC curve of 0.613 (P = 0.039)., Conclusion: The significant correlation between CRL discrepancy and birthweight discordance in spontaneous versus IVF MC twin pregnancies might suggest differential monozygotic twinning process., (© 2015 John Wiley & Sons, Ltd.)

Objective: To compare the reproductive outcome of women who underwent blind dilatation and curettage (D&C) with those who underwent hysteroscopic resection of pathologically confirmed retained products of conception (RPOC)., Methods: Medical records of women who underwent either D&C or hysteroscopic resection of RPOC at Assaf Harofeh Medical Center, Israel, between 2000 and 2010 were retrospectively reviewed., Results: A total of 177 women with pathologically confirmed RPOC underwent either D&C (n=94, 53.1%) or hysteroscopy (n=83, 46.9%). Mean time to conception was significantly shorter after hysteroscopy than after D&C (7.4±7 vs 12.9±16.8 months, P=0.037). Rate of occurrence of a newly diagnosed infertility problem was significantly higher following D&C than hysteroscopy (23 [24.5%] vs 10 [12.0%]; P=0.034). Etiology of the new problem was mechanical, including tubal occlusion and intrauterine adhesions. Logistic regression comparing both methods revealed that hysteroscopic resection was associated with a significant reduction in the occurrence of a new infertility problem compared with D&C (OR 0.42; 95% CI, 0.18-0.96, P=0.04)., Conclusion: Hysteroscopic removal of RPOC is associated with a shorter mean time to further conception and a lower rate of occurrence of newly diagnosed infertility problems than D&C., (Copyright © 2014 International Federation of Gynecology and Obstetrics.

Objective: This study aimed to compare the associations of crown-rump length (CRL) discrepancy with birthweight discordance in spontaneous versus vitro fertilization (IVF) conceived dichorionic twin pregnancies., Method: A computerized retrospective study of women referred to our ultrasonographic unit for nuchal translucency examination between January 1997 and December 2011. The study group was subdivided into twins conceived after IVF, non-IVF fertility treatment and spontaneously conceived twins. Birthweight discordance was defined as a difference of birthweights of >20%., Results: A total of 688 dichorionic twin pregnancies were included, all of them ending in live birth of both twins. IVF-conceived pregnancies were associated with a significant increased risk of extreme birthweight discordance compared with spontaneous-conceived twin pregnancies (OR = 2.3; CI = 1.4-3.8, P < 0.001). A significant correlation was found between CRL discrepancy and birthweight discordance in spontaneous-conceived pregnancies (r = 0.15, P < 0.05). In contrast, there was no significant correlation between CRL discrepancy and birthweight discordance in both IVF and fertility treatment-conceived pregnancies., Conclusion: Because birthweight discordance in IVF-conceived twins did not correlate with CRL discrepancy, we assume that it emerges later in pregnancy, maybe related to maternal underplaying complications, for which IVF was indicated in the first place., (© 2014 John Wiley & Sons, Ltd.)

Objective: To address the consequences of surgical curettage following failed medical abortion., Methods: A retrospective case-control study was performed in a tertiary gynecologic department. The case group comprised 104 women who underwent surgical curettage following failed medical abortion; the control group included 104 women who underwent early surgically induced abortion. Clinical characteristics and surgical findings were examined. The extent of inflammation was quantified following immunohistochemical staining for cell-surface markers characteristic of T lymphocytes, B lymphocytes, and macrophages. The extent of necrosis was evaluated morphologically., Results: Abnormal findings during surgical curettage were significantly more prevalent among women in the case group than in the control group (10.6% versus 1.9%; P=0.019). The most frequent abnormality in the case group was the presence of intimately adherent products of conception, necessitating sharp curettage. The extent of inflammation (represented by increased numbers of T and B lymphocytes) was greater in the case group than in the control group (P=0.046 and P=0.001, respectively), as was the extent of necrosis (P<0.05)., Conclusion: Curettage following failed medical abortion harbors particular difficulties, which may be attributed to an inflammatory response. The long-term consequences of curettage following failed medical abortion warrant further investigation., (Copyright © 2012 International Federation of Gynecology and Obstetrics.

Objective: To characterize the clinical and laboratory features of coagulopathy following second-trimester surgical abortions. DESIGN. Retrospective study., Setting: Gynecologic unit of a university-affiliated medical center., Population: 1249 consecutive women underwent late second-trimester (16-24 weeks) surgical abortions between January 2002 and June 2010. Of those, 20 women (1.6%) were diagnosed with excessive bleeding accompanied by coagulopathy., Methods: Women were divided into two groups based on whether the abortion was performed for fetal demise (n=14) or pregnancy termination (n=6)., Main Outcome Measures: Gestational age, indication for abortion, blood clotting tests, number of blood products and coagulation factors administered., Results: Women who had pregnancy termination began to bleed significantly earlier than those with fetal demise (p<0.05). A significantly higher number of women with fetal demise had a gradual deterioration of the clotting test, compared with women who had pregnancy termination (p<0.05). In women with fetal demise, early bleeding was associated with a more severe clinical presentation., Conclusions: Coagulopathy following surgical abortion manifests differentially in women who have fetal demise and those who have pregnancy termination, implying a different pathophysiology. Women with fetal demise suffering from excessive bleeding following surgical abortion accompanied with mild clotting test abnormalities should be carefully monitored to diagnose and treat an impending disseminated intravascular coagulation., (© 2011 The Authors Acta Obstetricia et Gynecologica Scandinavica © 2011 Nordic Federation of Societies of Obstetrics and Gynecology.)

Objective: To assess the distribution of fetal indications leading to termination of pregnancy (TOP) in our institute., Methods: All pregnant women with singleton pregnancies who underwent TOP due to fetal abnormalities in our institute between January, 1998 and December, 2004 were divided between early TOP (<23 weeks' gestation) and late TOP (> or =23 weeks' gestation)., Results: There were 328 (71%) and 134 (29%) early and late TOPs, respectively. The TOPs were performed at a mean gestational age of 20.1 +/- 4.8 weeks. The groups varied significantly in the indications for TOP (p = 0.04), which were primarily structural abnormalities (mostly CNS) followed by chromosomal/genetic defects. Fetal structural abnormalities were more common in the late TOP group (62.7% vs 54.2%) while chromosomal-genetic defects were more common in the early TOP group (40% vs 29.1%, respectively). Fetal infection (mostly cytomegalovirus) was similar ( approximately 4%) for both groups. The early TOP group had significantly more hydrops, gastrointestinal, face and neck abnormalities, while the late TOP group had significantly more cardiovascular abnormalities (p < 0.01)., Conclusions: The impact of early chromosomal/genetic screening contributes to early TOPs, while midgestation anomaly and cardiac scanning significantly contribute to late TOPs. Fetal infection contributes equally to both categories of TOPs.

Background: The Israeli Ministry of Health reported an increased rate of twin pregnancies among all cases locally diagnosed as having open neural tube defects. The current study aimed to evaluate whether the etiology of this phenomenon could be attributed either to the twinning or to the mode of conception., Methods: Women admitted to our hospital between January 1997 and July 2004 for termination of pregnancy because of severe fetal abnormality enrolled into this retrospective case series study. They were further subdivided according to mode of conception (spontaneous, in vitro fertilization (IVF) or intracytoplasmic sperm injection (IVF-ICSI) pregnancies)., Results: Three-hundred and eighty consecutive pregnancies, of which 340 (89%) were singletons, participated in our study. Anencephaly was diagnosed in 26 cases: 19 singletons and 7 twins. In the entire twin population, they were all dichorionic twins and only one co-twin was affected. Five of the twins were conceived by IVF-ICSI. All the anencephalic IVF-ICSI twins had normal karyotypes. All IVF-ICSI study women had taken folic acid 400 mcg/day 3 months before conception and throughout the first trimester of pregnancy. In order to find out the cause of the high rate of anencephaly found in IVF-ICSI pregnancies (33.3%), either the twinning or the IVF-ICSI process, a logistic regression analysis was used. A significant correlation was found only between anencephaly and twinning (p = 0.001, CI = 1.86-12.63), with a risk ratio of 4.85., Conclusions: Our case series data suggest a comparatively higher rate of anencephaly in IVF-ICSI pregnancy secondary to twinning and not because of the assisted reproductive technology. It is suggested that larger epidemiologic studies are conducted to validate our preliminary results., (Copyright 2005 John Wiley & Sons, Ltd.)
