The study was conducted to investigate the association of placental morphological and histopathological features with term, singleton pregnancies obtained by assisted reproductive technologies (ART). The study group comprised 45 consecutive women with a singleton pregnancy, obtained by ART, who delivered at term. For each subject in the study group, the consecutive, matched-for-age-and-parity woman, with a term singleton, spontaneously conceived pregnancy served as the controls. The placentae of both groups were subject to a detailed morphological and histopathological investigation by one pathologist, who was blinded to specimen origin. Pregnancy complications, fetal weight and perinatal outcome were similar in both groups. No differences in morphological or histopathological features of the placenta were observed between the groups. Nevertheless, the placentae of the study group showed a borderline, significantly higher placental weight and placental:fetal weight ratio, and placental thickness was significantly higher. Abnormal umbilical cord insertion was significantly more prevalent in the study group. Neither the specific ART method employed, nor the infertility factor affected the results, suggesting that multiple embryo transfers and/or ovulation induction protocols may account for these differences.

The study was conducted to determine whether altered plasma concentrations of soluble selectins are involved in the pathogenesis of pre-eclampsia. Maternal plasma samples were collected from 20 patients with pre-eclampsia, and from 20 matched normotensive patients with uncomplicated pregnancies. Samples were assayed for soluble endothelial selectin (sES), platelet selectin (sPS) and leukocyte selectin (sLS) by specific enzyme-linked immunosorbent assay. The three soluble selectins were detectable in the plasma of all pre-eclamptic and control patients. The mean plasma concentrations of sPS and sLS were comparable between the groups. However, the mean plasma concentration of sES was significantly higher in the pre-eclamptic group compared with the control group (61 ng/ml ± 30 ng/ml compared with 40 ng/ml ± 17 ng/ml; P < 0.01). The selective increased plasma concentrations of sES in patients with pre-eclampsia provide specific evidence for endothelial activation and may reflect distinct pathways for neutrophil activation in pre-eclampsia.

Objective: To examine maternal and neonatal outcomes of isolated proteinuria and define maternal characteristics for progression to pre-eclampsia., Study Design: Retrospective cohort study. Data from all hospitalized pregnant women between 2009 and 2014 with new onset isolated proteinuria of over 300 mg/24 h at admission were obtained. Follow-up was performed from the time of admission to the hospital to the time of discharge postpartum. Obstetrical, maternal and neonatal outcomes were obtained., Result: Ninety-five pregnant women diagnosed with new onset isolated proteinuria were followed to term. Thirteen women developed pre-eclampsia during pregnancy and eight developed pre-eclampsia postpartum. Maternal characteristics for progression to pre-eclampsia were greater maximal values of proteinuria. Earlier pre-eclampsia onset was associated with early-onset proteinuria and multiple gestation. Although greater values of proteinuria were associated with increased risk for intrauterine growth restriction and lower Apgar scores, maternal outcome was favorable, regardless of pre-eclampsia progression. Isolated proteinuria progressing to pre-eclampsia was associated with late pre-eclampsia onset and favorable maternal and neonatal outcomes., Conclusion: A significant proportion of women with new onset isolated proteinuria will develop pre-eclampsia. In these women, close follow-up is recommended until after delivery.

Background: The effects of consecutive pregnancies on the course of idiopathic intracranial hypertension (IIH) are unclear in view of the scarce published data., Objectives: To evaluate the course and management of visual and pregnancy outcomes of consecutive pregnancies with IIH., Methods: The medical records of women with IIH in consecutive pregnancies were reviewed for neuro-ophthalmological findings, management, and visual and pregnancy outcomes., Results: The study group comprised eight women with at least two consecutive pregnancies (mean age 27.3 +/- 5.3 years). The mean duration of IIH prior to the first pregnancy was 3.4 +/- 3.16 years. One woman with IIH pre-pregnancy symptoms and three women with clinical features of IIH during the second trimester of pregnancy (gestational week 21.7 +/- 4.04) were treated with acetazolamide (250 mg every 8 hours). Symptoms resolved, resulting in uncomplicated first deliveries for all four. The first deliveries of four other women were by cesarean section due to obstetric indications. Only one woman developed symptoms and signs of IIH during her second pregnancy and was thus treated with acetazolamide. Two women who completed three pregnancies had no IIH symptoms during their pregnancies. The course and outcome of those pregnancies were normal., Conclusions: IIH apparently does not worsen or even become symptomatic in consecutive pregnancies. The appropriate management of IIH in pregnant women is similar to management for non-pregnant women; neither the course nor the obstetric outcome of first and consecutive pregnancies is influenced by the presence of IIH.

Background: Pregnant women with pathological conditions requiring a neurosurgical intervention pose a unique therapeutic challenge. Changes in normal physiology add to the complexity of patient management. We describe our experience in treating various neurosurgical diseases in parturient women., Methods: Thirty-four pregnant and early postpartum women were treated at our center between 2003 and 2010. The general guideline used in these patients (now deserving re-evaluation based on the presented data) was to postpone surgery until the patient reached term (weeks 34-38 of gestation) unless there was evidence of a life- or function-threatening condition, in which case surgery was promptly performed., Results: Sixteen patients underwent neurosurgical intervention during pregnancy between 11 to 34 weeks of gestation (7 tumor, 3 vascular, 2 VP shunt, 2 spinal, 2 trauma). Thirteen women underwent a neurosurgical procedure after delivery (12 tumor, 1 spine), and 5 women were treated conservatively (2 vascular lesions, 3 trauma). Three patients underwent abortions (one spontaneous and two elective). The other 31 women delivered at 30-42 weeks' gestation. Of 12 patients whose definitive neurosurgical procedure was initially delayed, 5 were not able to complete their pregnancy naturally. Of 21 patients that underwent a cesarean section (CS), 3 were performed urgently. Although two pairs of twins and two singletons had an initial low Apgar score (<7), the outcome for all the neonates was good. Neurosurgical outcome was satisfactory., Conclusions: Our experience demonstrates the safety of neurosurgical intervention and anesthesia during pregnancy. Delaying intervention often resulted in maternal deterioration and urgent intervention. Thus, pregnancy by itself should not be considered a major contraindication for performing a neurosurgical procedure, which should be considered early rather than late in most patients.

This paper reports a case of S. constellatus chorioamnionitis in a pregnant Crohn's disease patient who was taking azathioprine. Chorioamnionitis is a major cause of perinatal morbidity. Azathioprine, an immunosuppressive antimetabolite, is widely used to treat inflammatory bowel disease. Streptococcus constellatus is a Gram-positive bacterium that has not previously been associated with chorioamnionitis. A high index of suspicion for chorioamnionitis and unusual pathogens should be maintained in the management of obstetric patients on immunosuppressive agents.

Background: Foreign workers in Israel are not covered by the comprehensive medical insurance that all Israelis receive. They have national insurance and injury-related coverage, which does not include routine pregnancy follow-up, Objectives: To compare perinatal outcome between partially insured non-resident migrants in Israel and comprehensively insured Israeli women., Methods: Parameters of perinatal outcome were compared between 16,012 Israeli and 721 foreign women living in Israel. Outcome measures included birth weight, distribution of gestational age at delivery, neonatal complications, cesarean section, neonatal intensive care unit admission, intrauterine fetal death rates, and duration of post-partum hospitalization., Results: Deliveries prior to 28 weeks gestation occurred more frequently among non-residents (1.3% vs. 0.6%, P < 0.001). Gestational diabetes and preeclamptic toxemia were significantly more prevalent among non-residents (3.2% vs. 1.9%, P < 0.05 and 4.9% vs. 3.1%, P < 0.05, respectively). The cesarean rates were 18% and 35% for residents and non-residents, respectively (P < 0.001), and the post-cesarean recovery period was longer among non-residents (4.8 vs. 3.6 days, P < 0.05). The mean birth weight was similar in the two groups (3,214 vs. 3,231 g), although macrosomia (>4,000 g) was more prevalent among non-residents, who also had higher rates of NICU admission ((9.6% vs. 8%, P < 0.05) and intrauterine fetal death (6.6/1,000 vs. 3.7/1,000, P < 0.05)., Conclusions: Non-resident parturients in Israel are more susceptible to an adverse perinatal outcome than their Israeli counterparts. We suggest that government subsidization of non-residents' health expenditures would reduce the differences in perinatal outcome between these two groups.

Background: We investigated whether hereditary thrombophilia is more prevalent in women with recurrent IVF-embryo transfer failures., Methods: This case-control study was conducted in an academic tertiary care hospital and compared 45 women with a history of four or more failed IVF cycles (group A) with 44 apparently healthy women matched for age and ethnic origin (group B). All participants were tested for inherited thrombophilias: mutations of prothrombin, factor V Leiden and methylene tetrahydrofolate reductase (MTHFR), and protein C, protein S and antithrombin III deficiencies., Results: Excluding homozygotic MTHFR, the incidence of thrombophilia in group A, was 26.7% compared with 9.1% in group B (P = 0.003; odds ratio 2.9; 95% confidence interval 1.02-8.4). The incidence of thrombophilia in women with unexplained infertility in group A was 42.9% (9/21), compared with 18.2% in group B (P < 0.002)., Conclusions: These data suggest that inherited thrombophilia may play a role in the aetiology of repeated IVF failures, particularly in the subgroup with unexplained fertility.

Pregnancy is hypercoagulable state. The field of thrombophilia; the tendency to thrombosis, has been developed rapidly and has been linked to many aspects of pregnancy. It is recently that severe pregnancy complications such as severe preeclampsia intrauterine growth retardation abruptio placentae and stillbirth has been shown to be associated with thrombophilia. Recurrent miscarriage and has also been associated with thrombophilia. Finally, thromboembolism in pregnancy as in the non-pregnant state is linked to thrombophilia. In this review all aspects of thrombophilia in pregnancy are discussed, and also all prophylactic and therapeutic implications.

Objectives: To assess the contribution of additional examiners to: the average discrepancy between estimated and actual fetal weights; the correlation between estimated and actual fetal weights; the reduction in major (> 10%) discrepancies between estimated and actual fetal weights., Design: Three experienced sonographers independently measured fetal biparietal diameter, head circumference, abdominal circumference and femur length in 39 fetuses at term. The estimated fetal weights were calculated for each examiner. Fetal biometric measurements were analyzed to obtain the source of differences in estimations among the examiners. Discrepancy, correlation and number of major (> 10%) discrepancies between the estimated and actual fetal weights were calculated for each examiner, and the contribution of additional examiners was analyzed., Results: The differences in measurements of the biparietal diameter and femur length were lower than those of the head and abdominal circumferences. For each of the three examiners, the average discrepancy between the estimated and actual fetal weights was 6.1%, 5.9% and 6.3%. When the estimation was based on two examiners, the discrepancy decreased to 4.8-5.6%. The contribution of a third examiner was nil. Major (> 10%) discrepancies between estimated fetal weight and actual birth weight were found in seven, eight and nine estimations of the examiners. Estimation by two examiners decreased the number of major discrepancies, and estimation by all three examiners further decreased by approximately 50% the number of major discrepancies between the estimated and actual fetal weights., Conclusion: Measurements by multiple examiners changes only slightly the average number of discrepancies between estimated and actual fetal weights. However, the reduction in major (> 10%) discrepancies is statistically and clinically significant.

Objectives: To conduct a prospective evaluation of the incidence and neonatal outcome of fetuses with persistent right umbilical vein. This condition had traditionally been considered to be extremely rare and to be associated with a very poor neonatal prognosis, but later evidence has raised some doubts about the veracity of these contentions., Methods: Between August 1995 and November 1998, 8950 low-risk patients were prospectively evaluated at two medical centers. The sonographic diagnosis of a persistent right umbilical vein was made in a transverse section of the fetal abdomen when the portal vein was curved toward the stomach, and the fetal gall bladder was located medially to the umbilical vein., Results: Persistent right umbilical vein was detected in 17 fetuses during the study. Four of them had additional malformations, of which three had been detected antenatally., Conclusions: We established that the incidence of persistent right umbilical vein in a low-risk population is 1 : 526. We believe that the sonographic finding of this anomaly is an indication for conducting targeted fetal sonography and echocardiography. When the persistent right umbilical vein is connected to the portal system and other anomalies are ruled out, the prognosis can generally be expected to be favorable.

Background and Purpose: The aim of our study was to investigate the association of transient ischemic cerebrovascular events during pregnancy and inherited thrombophilias., Methods: The study group comprised previously healthy pregnant women who had their first ischemic event during pregnancy (n=12). The control group included 24 healthy women matched with the study women for age, ethnicity, and smoking status. All women were evaluated for factor V Leiden mutation, methylenetetrahydrofolate reductase C677T gene mutation, the G20210A mutation in the prothrombin gene, and deficiencies of plasma proteins C and S and antithrombin III., Results: Inherited thrombophilia was detected in 83% of women with transient neurological manifestations compared with 17% of the control group (P<0.001)., Conclusions: Transient cerebrovascular ischemic events during pregnancy are associated with a high rate of inherited thrombophilias. Pregnant women with focal neurological symptoms should be evaluated for thrombophilia.

Objective: To determine whether plasma and peritoneal fluid levels of soluble vascular cell adhesion molecule-1 (sVCAM-1) and soluble intercellular adhesion molecule-1 (sICAM-1) are altered in women with ovarian hyperstimulation syndrome (OHSS)., Design: Prospective, case-control study., Setting: Lis Maternity Hospital and the Sara Racine IVF Unit, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel., Patient(s): The study group comprised 16 women with severe OHSS. The control groups comprised 10 women treated with controlled ovarian hyperstimulation and 8 women with normal findings at diagnostic laparoscopy., Intervention(s): Plasma samples were obtained from the study group and the first control group. Peritoneal fluid samples were obtained during paracentesis from the study group and during diagnostic laparoscopy from the second control group., Main Outcome Measure(s): Samples were assayed by specific ELISA for sVCAM-1 and sICAM-1., Result(s): The mean peritoneal fluid levels of sVCAM-1 and sICAM-1 and the mean plasma levels of sVCAM-1 were significantly higher in the women with OHSS than in the control groups. However, the mean plasma levels of sICAM-1 were comparable. A positive correlation was demonstrated between the levels of sVCAM-1 and plasma E2 at the time of hCG administration and between the levels of sICAM-1 and number of ova retrieved., Conclusion(s): Our findings suggest that soluble cell adhesion molecules may have a role in the pathogenesis and progression of OHSS.

Klippel-Trénaunay-Weber syndrome is a rare congenital deep-vein malformation. Pregnancy in patients with this syndrome is rare and only a few cases have been reported. Known obstetrical risks in pregnant patients with this syndrome include bleeding from angiomata in the genitalia, and coagulation disturbances. We present a 31 year old woman with this syndrome who, on two occasions, delivered small-for-gestational-age neonates. This may have been due to placental insufficiency caused by angiomatosis related to the syndrome.

Objective: This study was to determine the significance of meconium in the amniotic fluid of pregnancies complicated by preterm premature rupture of membranes (PPROM) without labor., Methods: A case-control study of 31 pregnancies complicated by PPROM at 27-36 weeks gestation with meconium present (study group) and 93 pregnancies complicated by PPROM but without meconium was performed. The patients were matched for year of delivery, gestational age, race, and parity. Pregnancy and neonatal outcome variables of the 2 groups were compared., Results: The incidence of early onset neonatal sepsis was significantly increased in the study group (16.1% vs. 1.1%; P < 0.001). Similarly, chorioamnionitis (48.3% vs. 22.5%; P < 0.01), cesarean delivery for a nonreassuring fetal heart rate pattern (19.4% vs. 3.2%; P < 0.01), a 5-min Apgar score < 7 (22.5% vs. 8.6%; P < 0.05), and fetal growth retardation (FGR) (12.9% vs. 2.2%; P < 0.05) were also more common in pregnancies complicated by PPROM with meconium. The mean umbilical cord arterial pH was significantly lower in these pregnancies (7.18 +/- 0.07 vs. 7.28 +/- 0.08; P < 0.001). After controlling for confounding variables with multiple logistic regression analysis, we found that meconium in the amniotic fluid remained associated with early onset neonatal sepsis., Conclusions: The presence of meconium in the amniotic fluid of pregnancies complicated by PPROM is associated with an increased incidence of early onset neonatal group B beta-hemolytic streptococcus (GBBS) sepsis.
