STUDY DESIGN: The comparison was made between 52 twin pregnancies conceived by ART and 80 spontaneous twins, deliv ered between y ears 2002 and 2004. Statistical analysis was perf ormed by the SPSS program, v ersion 11.5. RESULTS: Rates of nulliparity, preterm labor, incidence of caesarean section, hospitalization time and neonatal mortality were signif icantly higher in the ART group. ART itself was not a risk f actor for specif ic pregnancy complications such as pregnancy-induced hy pertension, gestational diabetes mellitus and premature rupture of membranes. Gestational age at deliv ery, the birth weights of both the first and second twins were comparable between the groups.

Study design: In a cross-sectional case–control study, 40 women with ICP were compared with 40 gestational age-matched healthy controls. The isovolumetric contraction time (ICT), isovolumetric relaxation time (IRT), and ejection time (ET) were measured using the Doppler signals of the opening and closing of the mitral and aortic valves. LMPI was calculated as (ICT + IRT)/ET. An adverse perinatal outcome was defined with at least one of the following: non-reassuring fetal heart rate tracing, umbilical cord pH <7.20, the presence of meconium in amnion, and neonatal intensive care unit (NICU) admission. Results: Mean gestational age at delivery and mean birth weight were significantly lower and the incidences of cesarean section rate, non-reassuring fetal heart rate tracing, the presence of meconium in amnion, and NICU admission were significantly higher in the ICP group (p < .01). Mean LMPI, ICT, and IRT values were significantly higher in the ICP group (p < .01). The area under the receiver operating characteristic (ROC) curve for LMPI in prediction of adverse perinatal outcome was 0.740 (95% CI: 0.607–0.873, p = .001) and a cut-off LMPI of 0.41 conferred a sensitivity of 85% and a specificity of 61%. Conclusions: There is an impaired global ventricular function in ICP fetuses demonstrated by increased LMPI. High LMPI is associated with adverse perinatal outcome in ICP.

This study was conducted on 60 women with PPROM, 50 women with TPL and 47 healthy pregnant women. Laboratory parameters (including complete blood count, C-reactive protein (CRP)) of all the participants were recorded. The neutrophil-to-lymphocyte ratio (NLR) values were significantly higher in PPROM group than TPL group and healthy control group (6.1 ± 3.9, 4.4 ± 1.7, 4.4 ± 2.2, p = .007, p = .018, respectively). At a cut-off level of 5.14, NLR accurately predicted occurrence of neonatal sepsis (AUC = 0.717 (95% confidence interval 0.610–0.824), p = .001) with sensitivity and specificity rates of 69.7% and 72.0%, respectively. In the management of the patients with PPROM, NLR can be used as a more cost-effective method than other blood parameters that require the use of a kit. IMPACT STATEMENT What is already known on this subject? There is only one study in the literature evaluating blood count parameters (such as platelet-to-lymphocyte ratio (PLR), NLR) in PPROM pregnancies. That study demonstrated PLR and NLR were both higher in the PPROM group. What do the results of this study add? The present study demonstrates that only NLR is higher in the PPROM group. Furthermore, we have also demonstrated distinctively that NLR can predict occurrence of neonatal sepsis. What are the implications of these findings for clinical practice and/or further research? High values of NLR may be useful for predicting adverse outcomes in PPROM and TPL patients as a cost-effective method. Further studies are needed to determine whether these parameters can be used to predict if a pregnant woman who is at risk of preterm labour will result in adverse perinatal outcome.

Material and methods A total of 93 cesarean section deliveries after 34 + 0/7 gestational week (GW) were evaluated. The study (n = 50) and control (n = 43) groups consisted of type III and type I nonstress test (NST) according to the 2008 National Institute of Child Health and Human Development workshop report on electronic fetal monitoring. The serum levels of ProBNP II, S100-B, CK-MB, and cTnT were measured in cord blood and were evaluated according to the NST results, cord-blood gas analyses (pH and base-excess values) and 1- and 5-minute Apgar scores. Exclusion criteria for both groups included congenital abnormalities, multiple pregnancy, chorioamnionitis, oligohydramnios, polyhydramnios, intrauterine growth retardation (IUGR), and placental abruption. Results Mean age, weight, height, gestational age, and birth weight were comparable in type I and III NST groups. 1- and 5- minute Apgar, umbilical artery and vein pH values, and base deficiency were significantly lower in type III NST group compared to the type I NST group. The serum 100B (1616 ± 119 versus 533 ± 95 ng/L, p < .001), CK-MB (28.67 ± 21.17 versus 14.20 ± 11.26 ng/L, p < .001), cTnT (657 ± 396 versus 230 ± 132 ng/L, p < .001) and proBNP (1727 ± 379 versus 1069 ± 721 ng/L, p < .001) levels were significantly elevated in the NST type III compared to the NST type I group. The serum 100B, CK-MB, cTnT and proBNP levels were significantly elevated in the cord pH < 7.00 (n = 10) compared to pH = 7.00–7.15 group (n = 18). The serum 100B and proBNP were significantly elevated in the cord pH = 7.00–7.15 compared to the pH > 7.15 group (n = 65), whereas serum cTnT and proBNP levels were comparable in the latter two groups. In the study group, S100B, cTnT, and proBNP had negative correlations with 1- and 5-minute Apgar scores. All of the four markers showed negative correlations with A. umbilicalis pH and base excess. Conclusions Mean S100B, CK-MB, cTnT, and NT-proBNP were significantly higher in the study group compared to the control group. The serum 100B, CK-MB, cTnT, and proBNP levels were significantly elevated in the cord pH < 7.00 compared to pH = 7.00–7.15 group. The serum 100B and proBNP were significantly elevated in the cord pH = 7.00–7.15 compared to the pH > 7.15 group.

Retinoic acid embryopathy is well defined in the literature. Case Report: The mother was referred for a fetal posterior fossa abnormality, first detected at 20 weeks of gestation. The mother used isotretinoin until 18 weeks gestation. Ultrasound examination revealed hypertelorism, cerebellar hypoplasia, vermian agenesis, truncus arteriosus, anotia, thymic aplasia, corpus callosum hypoplasia. An intrauterine diagnosis of fetal retinoid syndrome was confirmed by fetopsy after termination of pregnancy. Conclusion: The typical findings of fetal retinoid syndrome can be visualized with ultrasound in early second trimester.

MATERIAL AND METHODS This prospective study included 42 pregnant women with a possible diagnosis of intrauterine growth restriction based on obstetrical grayscale and Doppler ultrasonography and 42 women with a normal pregnancy during the 2nd and 3rd trimester. During follow-up examinations, seven fetuses showed an increased growth and were delivered with a birth-weight above the 10 percentile. However, for statistical purposes we included these seven patients in the IUGR group due to prospective nature of the study. All patients initially underwent obstetrical grayscale and Doppler ultrasonography with measurement of resistivity and pulsatility indices from uterine arteries. Subsequently, elasticity values of the peripheral and central part of the placentas from fetal and maternal surfaces were measured by shear-wave elastography. Following delivery, Apgar scores at 1st and 5th minute, birth weight were collected. For statistical analysis, Mann-Whitney U test was used. ROC curves were plotted and cut-off values for elasticity values were analyzed. RESULTS Median elasticity values of the central part of the placentas from maternal (28kPa vs 6kPa) and fetal sides (21.5kPa vs 5kPa) were significantly higher in IUGR pregnancies compared to the control group (p<0.001). Similarly, median elasticity values of peripheral part of placentas from maternal (22kPa vs 5.35kPa) and fetal sides (22.5kPa vs 5.3kPa) were significantly higher in IUGR pregnancies compared to the control group (p<0.001). CONCLUSION Placental stiffness values are significantly higher in patients with IUGR. Shear-wave elastography can be used as a non-invasive, complementary method to gray-scale and Doppler ultrasound for diagnosing IUGR.

To-date, only a few small studies have documented prenatal detection of aortic arch anomalies. In this article, we share our experience in detecting aortic arch anomalies. Foetal echocardiograms, clinic and genetic histories of 33 patients who had been diagnosed with aortic arch anomaly from 2007 to 2015 were reviewed. In 15 patients, right aortic arch with mirror image branching; in 13 patients, right aortic arch with left ductus arteriosus and aberrant left subclavian artery; in three patients, left aortic arch with aberrant right subclavian artery; in one patient bilateral ductus and right aortic arch with aberrant left subclavian artery and in one patient double aortic arch were detected. In a patient with isolated right aortic arch, 22q11 microdeletion had been revealed. Given this data, we strongly suggest foetal karyotype analysis when aortic arch anomalies are identif...

This cross-sectional study was conducted on 27 women with EO-PE, 27 women with LO-PE, and 26 healthy normotensive pregnant controls matched for gestational age. Maternal levels of serum HIF-1 α, progranulin, and syndecan-1 were measured with the use of an enzyme-linked immunosorbent assay kit. Statistical analysis revealed significant differences between the control and the PE groups in progranulin (p &lt; .001) and syndecan-1 (p &lt;.001) levels. There were no significant differences in the serum HIF-1 α levels between these groups (p= .069). When PE patients were evaluated by considering subgroups; statistical analysis revealed significant inter-group differences in all biomarkers. Serum progranulin levels were significantly higher in LO-PE compared with the other two groups (EO-PE versus LO-PE and LO-PE versus controls p = .000). Control group presented significantly higher syndecan-1 levels, than EO and LO-PE (p &lt; .001). HIF-1 α levels positively correlated with progranulin levels (r = .439, p= .000). Serum progranulin may have potential to be used as a biomarker for the differentiation of EO-PE and LO-PE. The co-operative action between HIF-1 α and progranulin might play a key role in the pathogenesis of LO-PE. The predominant feature of LO-PE seems to be an inflammatory process, whereas in EO-PE placentation problem seems to be the main pathology.

It is accepted that no correlation exists between fetal or neonatal platelet counts and mother’s thrombocytopenia. Actually spontoneus vaginal delivery without antepartum or intrapartum fetal platelet determination was the most reasonable method of delivery for pregnant with ITP. If there is any obstetrical indication cesarean delivery is preferred.

Thirty-three pregnant women with GDM according to the current criteria of the American Diabetes Association and 43 healthy pregnant women who were admitted to the antenatal clinic were recruited for this case-control study. Elasticity values of both the peripheral and the central parts of the placentas of the patients in both groups were determined by shear wave elastography (SWE) imaging. Mean elasticity values of both the central and the peripheral part of the placentas were significantly higher in GDM pregnancies (p < 0.001). No difference was observed in the mean elasticity values of the central and the peripheral part of the placentas in two groups (p > 0.05). SWE imaging technology might provide a quantitative assessment of the morphological pathologies of placentas in pregnant women with GDM.
