The aim of this study was to investigate the effect of maternal serum Vitamin D levels on the elasticity of placenta. Seventy-four spontaneously conceived singleton pregnancies in their first trimester were enrolled into this study. Fifty-one of them had Vitamin D deficiency (<20 ng/mL), while 23 pregnancies had Vitamin D levels ≥20 ng/mL. The placental elasticity was measured by the transabdominal Point Shear Wave Elastography (pSWE) method. In each case, the mean of 10 consecutive measurements was accepted as the mean placental elasticity value. The mean pSWE values did not significantly differ between the Vitamin D deficient group and the control group ( p  > .05). Placental elasticity was not found to be different in the pregnancies with Vitamin D deficiency during the first trimester.IMPACT STATEMENT What is already known on this subject? The pSWE technique provides opportunity to determine the elasticity of any interested tissue. Placental elasticity has been found to be changed in inflammatory and fibrotic conditions such as in preeclampsia, intrauterine growth restriction or diabetes. On the other hand, Vitamin D deficiency is linked with several comorbidities such as autoimmune disorders, cancer and cardiovascular disorders. Vitamin D also plays a role in placental angiogenesis in the first trimester. Maternal Vitamin D levels are shown to be related with adverse pregnancy outcomes. What do the results of this study add? To the best of our knowledge, this study is the first assessing the association between Vitamin D levels and placental elasticity. Placental elasticity was not found to be changed by Vitamin D deficiency. What are the implications of these findings for clinical practice and/or further research? Our pilot study revealed that Vitamin D deficiency does not have any impact on placental elasticity in the first trimester. However, longitudinal studies concerning placental elasticity in subsequent trimesters are needed to support our findings.

Purpose: Prenatal anxiety has negative effects on pregnancy and neonate. Both screening tests and invasive diagnostic tests are associated with elevated anxiety level. But a normal fetal karyotype result could improve the anxiety level in high-risk patients. We hypothesized that patients who prefer follow-up without karyotyping may experience increased anxiety and sleep impairment until delivery. Our aim was to determine the effect of invasive diagnostic test decision on anxiety and sleep quality in women with a positive screening result., Methods: 132 women were included for the study and three groups were described. The invasive group consisted of women who underwent invasive procedure after a screen-positive test result, the follow-up group consisted of women who preferred non-invasive follow-up after a screen-positive result and the control group consisted of women with screen-negative test results. Participants were evaluated with the State-Trait Anxiety Inventory (STAI) and the Pittsburgh Sleep Quality Index (PSQI) after genetic counseling. They were asked for completing the same questionnaires in the third trimester to establish the course of anxiety and sleep quality throughout pregnancy., Results: STAI scores were significantly higher in both screen-positive groups than in the control group in the first evaluation ( p  < 0.001). STAI scores decreased in the invasive group and controls while PSQI scores did not significantly change during the course of the pregnancy. However, the anxiety level and sleep quality were worsened over time in the follow-up group., Conclusion: Screen-positive women who preferred to follow up had higher anxiety level and worse sleep quality in the later stages of pregnancy. We concluded that invasive prenatal diagnostic tests could improve anxiety and sleep quality in pregnant women with a screen-positive result for aneuploidy.

Objectives: Increased placental stiffness is associated with various pathological conditions. Our objective was to evaluate the relation between the second-trimester placental elasticity value in low-risk pregnant women and poor obstetric outcomes., Methods: A total of 143 pregnant women were enrolled. Placental elasticity values were measured using the transabdominal point shear wave elastography method. 10 random measurements were obtained from different areas of the placenta. The mean was accepted as the mean placental elasticity value. Logistic regression analyses were performed to identify independent variables associated with obstetric outcomes., Results: Second-trimester placental elasticity value was significantly and positively associated with the poor obstetric outcomes (p=0.038). We could predict a poor outcome with 69.2% sensitivity and 60.7% specificity if we defined the placental elasticity cut-off as 3.19 kPa. Furthermore, in the multiple regression model, the placental elasticity value added significantly to the prediction of birth weight (p=0.043)., Conclusions: Our results showed that the pregnancies with a stiffer placenta in the second trimester were associated with an increased likelihood of exhibiting poor obstetric outcomes. Also, placental elasticity was independently associated with birth weight., (© 2020 Walter de Gruyter GmbH, Berlin/Boston.)

We aimed to assess the potential utility of myometrial and cervical elasticity measurement in the diagnosis of ectopic pregnancy (EP), which could facilitate the diagnosis process. Myometrial and cervical elasticity values were measured in women with EP, women with early intrauterine pregnancy (IP) and non-pregnant women. Transabdominal point shear wave elastography (pSWE) was used for elasticity measurements. A reliability study was performed in 20 patients of the non-pregnant group. Cervical pSWE showed poor reliability and high measurement failure rate; thus, we excluded cervical elasticity assessment from the study. In this study, 32 women with EP, 28 women with early IP and 38 non-pregnant women were enrolled for myometrial elasticity assessment by pSWE. Myometrial elasticity values were statistically significantly lower in EP (8.31 kPa [5.1-27]) and early IP (8.83 kPa [4.5-46.2]) groups than in non-pregnant women (14.85 kPa [5.1-28]) (p = 0.003). However, myometrial pSWE results were not significantly different between EP and early IP groups. In light of this data, quantitative assessment of the uterus elasticity using pSWE does not seem to be an adequate diagnostic method for EP., (Copyright © 2020 World Federation for Ultrasound in Medicine & Biology.

Objective: To investigate serum cortistatin levels in women with gestational diabetes mellitus (GDM) and women with uncomplicated pregnancies. Material and methods: This case-control study consisted of 40 pregnancies with GDM and 41 healthy singleton pregnancies matched for maternal and gestational age. The maternal serum levels of cortistatin were measured with enzyme-linked immunosorbent assay and compared between groups. Results: Cortistatin levels were significantly lower in GDM group (48.85 ± 20.18 versus 65.84 ± 33.98 ng/ml, p  = .008). There was a statistically significant difference in cortistatin levels between different treatment modalities and control group ( χ 2 (2) = 8.828, p  = .012). Pairwise comparisons showed that diet group had significantly lower CST levels than control group ( p  = .012). Serum cortistatin levels were negatively correlated with serum insulin and glucose levels and HOMA-IR ( r  = -0.358, p  = .001; r  = -0.303, p  = .006; r  = -0.444, p  < .001, respectively). Conclusion: Cortistatin levels were significantly lower in GDM pregnancies and related to serum insulin and glucose levels and HOMA-IR in pregnancy. This may help to better clarify the mechanism of GDM pathogenesis.

Objective: The current study aimed to investigate renal cortical elasticity (RCE) in early- and late-onset preeclampsia patients and compare the results with healthy controls. Materials and methods: The study consisted of 136 pregnant women. Three groups were identified as; the late-onset preeclampsia (LOP) group ( n  = 40), the early-onset preeclampsia (EOP) group ( n  = 32) and the control group ( n  = 64). RCE values were measured by point shear wave elastography (pSWE). Nine measurements were taken for each kidney and the mean of nine measurements was accepted as the mean RCE value for each kidney. The arithmetic mean of left and right RCE values was accepted as the overall RCE value of a subject. Groups were compared in terms of clinical and biochemical parameters, ultrasonography findings and pSWE values. Results: There was a statistically significant difference between groups in terms of overall RCE values (F[2,133] = 17.96, p  < .001). Post hoc comparisons indicated that both preeclampsia groups exhibited significantly higher RCE values than the control group. However, overall RCE values were not significantly different between the EOP and LOP groups. Overall RCE values were significantly and positively correlated with systolic blood pressure ( r  = 0.363, p  < .001), diastolic blood pressure ( r  = 0.347, p  < .001), proteinuria ( r  = 0.343, p  < .001), serum creatinine level ( r  = 0.181, p  = .035), serum uric acid level ( r  = 0.243, p  = .004) and blood urea nitrogen ( r  = 0.27, p  = .001). Conclusion: Our study demonstrated that maternal renal cortical stiffness increased in women with preeclampsia. The increased RCE values may be indicative for the severity of preeclampsia due to positive correlations between renal cortical stiffness and systolic - diastolic blood pressure and serum creatinine level.

Objective: Fetal hydronephrosis (FH) is the most common fetal renal pathology encountered in daily obstetric practice. Urinary and serum carbohydrate antigen 19-9 (CA 19-9) concentrations are elevated in obstructive renal pathologies. Our aim was to assess maternal urinary and serum CA 19-9 concentrations in pregnancies with FH and compare results with controls., Material and Methods: Twenty pregnancies with severe FH, 20 pregnancies with mild-moderate FH, and 20 healthy singleton pregnancies were included in this descriptive, case-control study. The diagnosis and classification of FH was based on the anterioposterior diameter of fetal renal pelvis. Maternal urinary and serum CA 19-9 concentrations were measured and compared between groups., Results: Severe FH cases had significantly higher maternal urinary CA 19-9 concentrations compared to controls (median: 75 vs 24 U/mL; respectively; p=0.014). Concentrations of CA 19-9 did not differ between the mild-moderate FH group and control group. No statistically significant difference was found between the groups with respect to maternal serum CA 19-9 concentrations., Conclusion: Our results show that maternal urinary CA 19-9 concentration is significantly higher in pregnancies with severe FH. However, no difference was detected in serum CA 19-9 concentrations between pregnancies with severe FH, mild-moderate FH and controls. If the mechanisms of transplacental passage and maternal urinary excretion are clarified, maternal urinary CA 19-9 may be a potential marker for indicating fetal kidney damage.

Objective : Perlecan is an extracellular matrix proteoglycan suggested to maintain endothelial functions. We aimed to measure maternal serum perlecan levels in different preeclampsia phenotypes. Methods : This study included 50 women with preeclampsia and 30 healthy pregnant women. Results : Serum perlecan levels were significantly higher (p = 0.016) in preeclamptic women with severe features(n = 23) than preeclampsia patients(n = 27). There were no statistically significant differences in serum perlecan levels between the early-onset preeclampsia(n = 25), late-onset preeclampsia(n = 25), and healthy pregnancies. Conclusion : Our findings suggest that preeclamptic women with severe features have higher serum perlecan levels than women with preeclampsia.

Spexin is a peptide that is involved in energy homeostasis and its expression is influenced by altered glucose metabolism. Gestational diabetes mellitus (GDM) is associated with increased insulin resistance (IR) and pregnancy is a progressive insulin resistant state. We hypothesized that spexin may have an effect on the pathophysiology of GDM which further could help to identify the disease. The aim of this study was to investigate spexin levels in the third trimester pregnancies with GDM and healthy controls. Thirty-nine women with GDM and 39 healthy singleton pregnancies were enrolled in this case-control study. Serum spexin concentrations were measured and correlated to biochemical and clinical parameters. Serum spexin levels were significantly higher in women with GDM (3686.25 ± 348.37 vs. 3472.33 ± 293.93 pg/ml, p =.004). Spexin levels ​​did not differ significantly according to treatment modality. Moreover, spexin levels were significantly positively correlated with homeostasis model assessment of IR (HOMA-IR). Spexin levels were significantly higher in women with GDM and closely related to HOMA-IR in the third trimester pregnancy. This may help to better clarify the pathophysiological role of spexin in GDM.

Background Placental elasticity varies in different diseases. Our objective was to evaluate placental elasticity using point shear wave elastography (pSWE) in pregnancies with intrauterine growth restriction (IUGR). Methods A total of 66 pregnant women with IUGR and 81 healthy pregnant women were enrolled. Placental elasticity was measured using the transabdominal pSWE method. Ten measurements were made, and the mean was accepted as the mean placental elasticity value in each case. The results for IUGR pregnancies and controls were compared. Results The mean pSWE values were significantly higher in pregnancies with IUGR, which means that women with IUGR have stiffer placentas (P < 0.001). Furthermore, the pSWE values were significantly and positively correlated with Doppler indices and adverse perinatal outcomes. Conclusion The pregnancies with IUGR had stiffer placentas than the healthy controls. The utilization of pSWE for placental elasticity may be useful in the diagnosis and management of IUGR as a supplement to the existing ultrasonography methods.

Aim: To study the efficacy of pirfenidone for prevention of postoperative adhesion formation in an adhesion rat model., Materials and Methods: Eighteen female Wistar rats were subjected to right-sided parietal peritoneum and right uterine horn adhesion model. Rats were randomized into three groups: group 1 (control) (closure of midline abdominal incision without any agent administration), group 2 (closure of incision after intraperitoneal administration of pirfenidone), and group 3 (closure of incision and only oral administration of pirfenidone for 14 days). Relaparotomy was performed 14 days after the first surgery. Effect of pirfenidone on adhesion formation was assessed on light microscopy by scoring vascular proliferation, inflammation, fibrosis, and collagen formation in the scarred tissue. Effect of pirfenidone on inflammation was assessed by measurement of transforming growth factor-β and interleukin-17 levels in scarred tissue., Results: The degree of vascular proliferation (1.32 ± 0.39 versus 2.34 ± 0.46, p < 0.001), inflammation (1.60 ± 0.70 versus 2.60 ± 0.52, p < 0.01), and fibrosis (1.50 ± 0.53 versus 2.40 ± 0.52, p < 0.01) were less prominent in group 2 compared to group 1, respectively. Only vascular proliferation was found to be less prominent in group 3 compared to group 1 (1.60 ± 0.42 versus 2.34 ± 0.46, p < 0.01). Intraperitoneal and oral administration of pirfenidone reduced tissue levels of inflammatory markers (TGF-β and IL-17) in parietal and visceral peritoneum compared to control group. Intraperitoneal administration of pirfenidone compared to oral administration was more effective in reducing tissue levels of inflammatory markers., Conclusion: Pirfenidone is an effective agent on the prevention of postoperative vascular proliferation, inflammation and fibrosis in scarred tissue particularly with intraperitoneal administration.

Objectives: We aimed to evaluate the placental volume and placental mean gray value in gestational diabetes mellitus (GDM) and healthy placentas using three-dimensional (3D) ultrasound and Virtual Organ Computer-aided AnaLysis (VOCAL)., Methods: This case-control prospective study consisted of 39 singleton pregnancies complicated by GDM and 42 healthy singleton pregnancies matched for gestational age, maternal age and parity. Placental volume and placental volumetric mean gray values were evaluated. The placental volume (cm(3)) was analyzed using the VOCAL imaging analysis program and 3D histogram was used to calculate the volumetric mean gray value (%)., Results: Placental volume was significantly larger in GDM (411.59 ± 170.82 versus 343.86 ± 128.94 cm(3); p = 0.046). There was no significant difference in mean gray value between GDM and healthy placentas (36.65 ± 7.02 versus 38.71 ± 7.91, respectively; p = 0.277). Placental volume was significantly correlated with gestational week (r = 0.219, p = 0.035) and parity (r = 0.228, p = 0.048). There was negative significant relation between placental volume and umbilical artery systolic/diastolic ratio, pulsatility index and resistance index (r = -0.278, p = 0.007; r = -0.315, p = 0.002; r = -0.322, p = 0.001, respectively)., Conclusions: Placental volume increases significantly in GDM, whereas mean gray values do not alter significantly. These data may reflect the placental changes in GDM placentas that may help to understand the pathophysiology better.

Objective: We aimed to determine the normal ranges for biorbital (BOD) and interorbital distances (IOD) during the second trimester in Turkish women with normal pregnancies and to assess the correlation between BOD, IOD, and other fetal craniofacial structures and biometric parameters., Material and Methods: Our retrospective study comprised 1328 women with singleton normal pregnancies who had undergone ultrasonography (USG) examinations at 19-23 weeks of gestation in the second trimester screening. The measurements of BOD and IOD were obtained with the coronal section of the fetal face at the plane of orbits., Results: Mean BOD was 3.4±0.33 cm, whereas mean IOD was 1.28±0.24 cm. Correlation analysis revealed that BOD was significantly correlated with IOD, transcerebellar diameter (TCD), cisterna manga (CM), nuchal fold (NF), nasal bone (NB), biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), femur length (FL), and gestational week. There was a significant relation between IOD and the lateral ventricle posterior horn, TCD, CM, NF, NB, BPD, HC, AC, and FL., Conclusion: The reference ranges obtained in our study enabled accurate evaluation of BOD and IOD in the second trimester of normal pregnancies. USG detection of fetal orbital biometric anomalies may alert the clinician for different anomalies associated with abnormal development of eye.

Objectives: We aimed to evaluate the placental volume and placental mean gray value in preeclampsia and healthy placentas by using three-dimensional (3D) ultrasonography and Virtual Organ Computer-aided AnaLysis (VOCAL)., Methods: This case-control prospective study consisted of 27 singleton pregnancies complicated by preeclampsia and 54 healthy singleton pregnancies matched for gestational age, maternal age and parity. Placental volume and placental volumetric mean gray values were evaluated. The placental volume (cm(3)) was analyzed using the VOCAL imaging program, and 3D histogram was used to calculate the volumetric mean gray value (%)., Results: Preeclamptic and control group consisted of 27 (mean age: 28.90 ± 5.95 years, mean gestation: 32.0 ± 4.55 weeks) and 54 (mean age: 29.48 ± 5.78 years, mean gestation: 32.61 ± 4.23 weeks) singleton pregnancies, respectively. Placental volume was significantly smaller in preeclampsia (250.62 ± 91.69 versus 370.98 ± 167.82 cm(3); p = 0.001). Volumetric mean gray value of the placenta was significantly higher in preeclampsia (38.24 ± 8.41 versus 33.50 ± 8.90%; p = 0.043). Placental volume was significantly correlated with the estimated fetal weight (r = 0.319; p = 0.003). There was negative significant relation between placental volume and umbilical artery pulsatility index, resistance index and systolic/diastolic ratio (r = -0.244, p = 0.024; r = -0.283, p = 0.005; r = -0.241, p = 0.024, respectively)., Conclusions: Placental volume diminishes significantly in preeclampsia, whereas volumetric mean gray values increases. This may reflect the early alterations in preeclamptic placentas, which may help to understand the pathophysiology better.

The aim of this study is to evaluate the relationship between three-dimensional (3D) ultrasound measurements of placenta at 11-13(6) weeks' gestation and maternal serum levels of pregnancy associated plasma protein-A (PAPP-A), free beta human chorionic gonadotrophin (fβhCG), Doppler parameters in early pregnancy. This prospective study consisted of 334 singleton pregnancies at 11-13(6) weeks' gestation. Placental volume and placental volumetric mean grey values were evaluated. The placental volume (cm(3)) was analysed using the Virtual Organ Computer-aided AnaLysis (VOCAL) imaging program and 3D histogram was used to calculate the volumetric mean grey value (%). Mean maternal age was 28.35 ± 7.55. Mean gestational age was 12.29 ± 0.68 weeks. Placental volume was 77.04 ± 35.74 cm(3). Mean grey value of the placenta was 34.38 ± 8.02%. Correlation analysis revealed that placental volume was significantly correlated with the crown-rump length (r = 0.173, p = 0.002), gestational week (r = 0.116, p = 0.036), ductus venosus pulsatility index (r = -0.101, p = 0.04) and maternal weight (r = 0.099, p = 0.037). There was a significant relation between the mean grey value of the placenta and maternal age (r = 0.131, p = 0.02), nuchal translucency (r = -0.109, p = 0.048), PAPP-A (r = 0.108, p = 0.04) and fβhCG (r = 0.104, p = 0.042). Volumetry of the placenta can be carried out with a high percentage of 1st trimester pregnancies. Volumetry during the 1st trimester could be helpful because of the less advanced state of placentation. This examination is easy to perform and the measurements can be acquired correctly and quickly.

Objective: This is a case of a prenatally diagnosed non-immune hydrops fetalis (NIHF) associated with translocation t(5;11)(q22;p15). An association between NIHF and this translocation has not been reported previously., Case Report: The patient was referred to the perinatology clinic with hydrops fetalis diagnosis at 23 weeks' gestation. We noted that the fetus had bilateral pleural effusion, ascites, widespread subcutaneous edema, membranous ventricular septal defect, hypoplastic fifth finger middle phalanx, clinodactyly, single umbilical artery. We performed cordocentesis. Chromosomal analysis on blood showed a balanced translocation between the long arm of chromosome 5 and the short arm of chromosome 11 with karyotype of 46,XX,t(5;11)(q22;p15)., Conclusion: We present prenatal diagnosis of a de novo translocation (5;11) in a hydropic fetus with ultrason abnormalities. In our case, karyotype analysis of the fetus, mother and father provided evidence of a de novo translocation, that might explain the NIHF.

Objective: To evaluate the outcomes and management options in pregnancies with early onset oligohydramnios., Materials and Methods: The file datas of all pregnancies diagnosed as oligohydramnios or anhydramnios before 27 gestational weeks between January 2006 and September 2013 were evaluated retrospectively. The underlying pathology and associated anomalies, karyotype analysis, the outcome of the pregnancy (either termination or labour), and gestational week at the time of diagnosis were analyzed., Results: A total of 54 pregnancies were evaluated; mean gestational week at the time of the diagnosis was 19.8 ± 4.6. Mean maternal age was 27.28 ± 6.03. Thirty-seven pregnancies were anhydramniotic, 13 fetuses had associated anomalies, five of them had multicyctic dysplastic kidney, five had bilateral renal agenesis, one had hypoplastic right heart syndrome, one had clubfoot, and one had ventricular septal defect and cleft palate. Karyotyping was normal regarding the fetuses with structural anomalies. Nineteen patients had premature preterm rupture of membranes and 39 patients had termination of pregnancy., Conclusion: The prognosis of early onset oligohydramnios is poor. Main determinant is gestational week at the time of the diagnosis.

We aimed to evaluate the volumetric and echogenic alterations in placentas between the intrauterine growth restriction (IUGR) and normal pregnancies using three-dimensional ultrasound and virtual organ computer-aided analysis (VOCAL) software. This case-control prospective study consisted of 48 singleton pregnancies complicated by IUGR and 60 healthy singleton pregnancies matched for maternal age, gestational age and parity. Placental volume (PV) and placental volumetric mean grey values (MGV) were evaluated. PV (cm(3)) was analysed using the VOCAL imaging analysis program, and 3D histogram was used to calculate the volumetric MGV (%). PV was 278.50 ± 63.68 and 370.98 ± 97.82 cm(3) in IUGR and control groups, respectively (p = 0.004). MGV of the placenta was 38.24 ± 8.41 and 38.24 ± 8.41 in IUGR and control groups, respectively (p = 0.30). receiver operator curve (ROC) curve analysis revealed that area under curve was 0.731 for PV. Correlation analysis revealed that PV was significantly associated with estimated fetal weight (r = 0.319, p = 0.003), biparietal diameter (r = 0.346, p = 0.002), head circumference (r = 0.269, p = 0.019), abdominal circumference (r = 0.344, p = 0.002) and femur length (r = 0.328, p = 0.004). PV was inversely related to the umbilical artery pulsatility index (r = - 0.244, p = 0.017). To the best of our knowledge, this is the first study evaluating volumetric MGV in IUGR placentas by comparing them with healthy pregnancies. Our study showed that PV diminishes significantly in IUGR pregnancies, whereas volumetric MGV does not alter significantly.

Aim. Comparison of the rate of wound complications, pain, and patient satisfaction based on used subcuticular suture material. Methods. A total of 250 consecutive women undergoing primary and repeat cesarean section with low transverse incision were prospectively included. The primary outcome was wound complication rate including infection, dehiscence, hematoma, and hypertrophic scar formation within a 6-week period after operation. Secondary outcomes were skin closure time, the need for use of additional analgesic agent, pain score on numeric rating scale, cosmetic score, and patient scar satisfaction scale. Results. Absorbable polyglactin was used in 108 patients and nonabsorbable polypropylene was used in 142 patients. Wound complication rates were similar in primary and repeat cesarean groups based on the type of suture material. Skin closure time is longer in nonabsorbable suture material group in both primary and repeat cesarean groups. There was no difference between groups in terms of postoperative pain, need for additional analgesic use, late phase pain, and itching at the scar. Although the cosmetic results tended to be better in the nonabsorbable group in primary surgery patients, there was no significant difference in the visual satisfaction of the patients. Conclusions. Absorbable and nonabsorbable suture materials are comparable in cesarean section operation skin closure.

Objectives: The aim of the study was to evaluate the effeot of parity on uteroplacental blood flow during the first trimester in low-risk singleton pregnancies., Materials and Methods: Uterine artery Doppler examinations were performed in 190 singleton pregnancies between 11-14 gestational weeks. Twenty-five pregnancies were excluded from the study due to history ci preeclampsia, diabetes mellitus or inherited thrombophilia. A total of 165 low-risk singleton pregnancies were included in the study Mean uterine artery pulsatility index (P1) was recorded and compared between nulliparous and multiparous women. The relation between maternal age, gestational week, maternal weight, parity biochemica, markers and abnormal uterine artery Doppler flows was evaluated. T-test and logistic regression analyses were used for the statistical analysis., Results: A total of 165 singleton pregnancies without any risk factors for uteroplacental insufficiency were includec in the study Of them, 58 (36.7%) were nulliparous and 107(63.3%) were parous. Correlation analysis revealed that the uterine artery pulsatifity indices during the first trimester were not affected by maternal age and parity:, Conclusions: Mean uterine artery pulsatility indices are not different in nulliparous and multiparous low nisA pregnancies at 11-14 weeks of gestation.

Objective: To measure the intracranial translucency (IT) by establishing reference ranges in uncomplicated singleton Turkish pregnancies and to evaluate the association of IT with maternal serum biochemistry, gestational week, crown-rump length (CRL) measurement, nuchal translucency (NT) and ductus venosus Doppler velocimetry., Materials and Methods: 190 uncomplicated singleton pregnancies were included in the study. IT, NT and CRL measurements between 11-14 gestational weeks were obtained with mid-sagittal plane. Two independent measurements were taken and averaged to obtain the final measurement used in the calculations. Statistical analysis was performed with SPSS for Windows 20.0 software package. Correlation analysis was used to determine the association between IT and NT pregnancy-associated plasma protein-A (PAPP-A), free β-human chorionic gonadotropin (β-hCG) and CRL length. A p-value of <0.05 was considered statistically significant., Results: The assessment rate of IT was 167/190 (87.89%). The mean CRL length, gestational week, NT and IT measurements were 63.63±10.05 mm, 12.28±0.75 weeks, 1.23±0.43 mm (range: 0.20-2.68) and 2.29±0.49 mm (range: 0.18-3.80), respectively There was no significant correlation between IT and maternal serum PAPP-A MoM (r=-0.34, p=0.698) or maternal serum free β-hCG MoM (r=-0.79, p=0.363), respectively. There was weak but statistically significant correlation between IT with with maternal weight (r=0.172, p=0.047), CRL length (r =0.301, p<0.001), gestational week (r=0.286, p=0.001) and NT measurement (r=0.224, p=0.007), respectively. There was no significant association between IT with ductus venosus Doppler pulsatility index (r=0.108, p=0.213)., Conclusion: IT can be easily measured while scanning for NT. This study shows normal range values in healthy Turkish pregnancies. Consistent with recent data, our results show positive correlation with gestational week and CRL length. Maternal serum biochemistry does not have any effect on IT. Besides, our study highlights that IT is correlated with NT and adds newly to the literature that there is no correlation of IT with ductus venosus pulsatility index.

Gestational diabetes is a condition which is seen in 7% of pregnancies and have potential risks for both mother and fetus. Despite its importance, there is not any golden standard approaches to the diagnosis and management of the disease. The aim of this review was to investigate the advances in the diagnosis and management of gestational diabetes in recent years.

Objective: We aimed to evaluate ductus venosus Doppler waveforms before and after amniocentesis in order to investigate any effect of amniocentesis on fetal myocardial hemodynamics. We also evaluated the umbilical artery, uterine artery and fetal mid-cerebral artery Doppler waveforms in order to investigate any relationship with ductus venosus Doppler changes., Methods: The study population consisted of 56 singleton pregnancies having genetic amniocentesis. Twenty seven of them had transplacental needle insertion; whereas 29 of them had non-transplacental amniocentesis. Uterine artery, umbilical artery, mid-cerebral artery and ductus venosus pulsatiliy index and resistance index were measured just before and after amniocentesis., Results: Amniocentesis does not cause any significant changes in fetal ductus venosus Doppler waveforms. There is also no significant changes in uterine artery, umbilical artery, mid-cerebral artery pulsatility and resistance index., Conclusion: Amniocentesis-whether transplacental or not- does not cause any significant effect on fetal myocardial hemodynamics.

Objective: To analyze fetal abdominal defects diagnosed during the prenatal period in the perinatology department in a tertiary center in Turkey., Methods: This retrospective study consisted of 27 cases diagnosed with fetal abdominal wall defects between January 2011 and February 2014 in the perinatology outpatient clinic of Celal Bayar University, Manisa, Turkey., Results: Eighteen (66.7%) cases were diagnosed with omphalocele, 6 (22.2%) had gastroschisis, and 3 (11.1%) had limb body wall defects. Twenty-one (77.7%) patients diagnosed either as omphalocele or limb body wall defect were offered karyotype analysis; 11 (52.4%) of them accepted the intervention, and 2 of the 11 patients (18.2%) had abnormal karyotype. Regarding the omphalocele cases; 12 (66.6%) cases had isolated omphalocele, whereas 6 of the 18 cases (33.3%) had associated anomalies. Expectant management was performed in 8 (66.7%) of 12 isolated omphalocele cases. Two of the isolated omphalocele group (16.7%) had missed abortion, the other 2 (16.7%) had termination of the pregnancy because of the associated chromosomal anomaly (47,XXY and 45,X0). Three of the gastroschisis group (50%) had missed abortion, and the other 3 (50%) had expectant management with cesarean delivery between 38-39 gestational weeks. Cases with limb body wall defect were terminated due to the lethal condition., Conclusion: The prenatal diagnosis of fetal abdominal wall defects is important, because they differ greatly in terms of perinatal and neonatal morbidity and mortality due to underlying chromosomal abnormalities and associated structural anomalies.

We aimed to identify knowledge about cervical cancer (CC) and Pap test (PT) and the barriers why women do not have Pap test done. The study was conducted with a sample of 1,036 women. Overall, 64.4 % had heard of CC, 43.1 % had heard about PT and 24.7 % had had a test at least once. It was determined that women had moderate knowledge of cervical cancer but poor knowledge of Pap test. Knowledge of CC and PT was significantly better among employed and single women, who had higher education, no prior delivery, a higher income level and regular gynaecological examination. Common barriers to PT were lack of awareness, being uncomfortable with the procedure and not knowing where to go for a PT. Utilization of the PT will not increase unless knowledge is improved and barriers are eliminated. Healthcare professionals are the key persons to provide both knowledge and facilities towards the goal of CC prevention.

There are various factors related to postpartum depression. In this study we have aimed to determine the effect of mode of delivery on the risk of postpartum depression. A total of 318 women who applied for delivery were included in the study. Previously diagnosed fetal anomalies, preterm deliveries, stillbirths, and patients with need of intensive care unit were excluded from the study. Data about the patients were obtained during hospital stay. During the postpartum sixth week visit Edinburgh postnatal depression scale (EPDS) was applied. There was no significant difference between EPDS scores when compared according to age, education, gravidity, wanting the pregnancy, fear about birth, gender, family type, and income level (P > 0.05). Those who had experienced emesis during their pregnancy, had a history of depression, and were housewives had significantly higher EPDS scores (P < 0.05). Delivering by spontaneous vaginal birth, elective Cesarean section, or emergency Cesarean section had no effect on EPDS scores. In conclusion healthcare providers should be aware of postpartum depression risk in nonworking women with a history of emesis and depression and apply the EPDS to them for early detection of postpartum depression.

Objective: To investigate the effects of GnRH antagonist (GnRH-ant) and agonist (GnRH-a) in the prevention of postoperative pelvic adhesions by a visual scoring system and immunohistochemical methods in a rat uterine horn model., Design: Controlled experimental animal study., Setting: Animal laboratory at an academic research environment., Animal(s): Twenty-one Wistar albino rats., Intervention(s): Rats were randomized into three groups. One week before the operation the rats received either GnRH-ant or GnRH-a or saline solution; they then underwent surgical laparotomy, and both uterine horns were traumatized by a scalpel. Three weeks later, all rats were sacrificed and extension and severity of the adhesions in each group were scored by a visual scoring system. Adhesion tissues were evaluated immunohistochemically for vitronectin and u-PAR., Main Outcome Measure(s): Scores of extend and severity of adhesions and staining of vitronectin and u-PAR., Result(s): The extent of adhesion scores were 1.85 ± 0.86, 0.78 ± 1.05, and 0.42 ± 0.64, and the severity of adhesion scores were 1.71 ± 0.91, 0.57 ± 0.85, 0.50 ± 0.75 for control, GnRH-ant, and GnRH-a groups, respectively. The extent and severity of adhesions were significantly lower in both GnRH-ant and GnRH-a groups when compared with the control group. Adhesion extent scores in the GnRH-a group were lower than in the GnRH-ant group, but this difference was not significant. vitronectin and u-PAR staining were significantly greater in both the GnRH-ant and GnRH-a groups than in the control group., Conclusion(s): GnRH-ant as well as GnRH-a reduced postoperative adhesion formation in a rat model. This finding was supported immunohistochemically by vitronectin and u-PAR staining., (Copyright © 2011 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.)

Objective: The goal of this study was to detect endometrial leptin expression in proliferative and secretory phases and then to compare the results with that of hyperplastic endometrium., Material and Methods: Seventeen proliferative, 23 secretory phase and 18 hyperplastic endometrial tissues diagnosed in our hospital between 2002 and 2007 were included in the study. These samples were stained with leptin antibody using an immunohistochemical method. Endometrial glandular and surface epithelium and stroma were evaluated for staining distribution and intensity., Conclusion: Staining intensity seen in early proliferative phase samples (2.33±0.51) increased significantly throughout the middle (2.40±0.54) and late phases (2.83±0.40) (p<0.05). Early secretory phase samples had the least staining intensity (1.42±0.53), while it increased significantly in later periods (2.38±0.51) (p<0.05). There was no difference in staining intensity among proliferative, secretory and hyperplastic tissues (p>0.05)., Conclusion: Although endometrial leptin expression was observed in a differential manner throughout the whole menstrual period, no difference was seen in endometrial hyperplasia. We consider that leptin does not play a role in hyperplastic transformation of the endometrium.

Aim: The management of gynecological cancer patients mainly aims at prolonging survival but modern therapy focuses on good survival combined with a good quality of life (QoL). The aim of this study was to evaluate QoL and identify its associated factors in Turkish women with gynecologic cancer., Method: The study included 119 women diagnosed with endometrial, cervical, ovarian or vulvar cancer and treated at the Gynecologic Oncology Department of Celal Bayar University Faculty of Medicine. The data were collected between January and June 2011. QoL was measured with EORTC QLQ-C30 version 3.0. Relationships between clinical and socio- demographic characteristics and QoL scores were analyzed using the Mann-Whitney U, Kruskal Wallis and t-tests., Result: Global health status, physical and role function scores were found higher in women under the age of 60 years. Role function scores were found lower, and emotional and social scores were found to be higher in single women than in married women. Physical scores were found higher in women who had graduated from secondary school or above. Women with ovarian cancer had the highest while women with cervical cancer had the lowest global health score (65.3 ± 24.7 and 43.0 ± 24.1, respectively). Women with endometrial cancer were found to have better role function, and social well being than those with vulvar, cervical or ovarian cancer. Global, physical, role function, cognitive and social scores were found higher in women who had been treated with surgery., Conclusion: Gynecological cancer and treatment processes cause significant problems that have negative effects on physical, emotional, social and role function aspects of QoL. Health care providers play a key role in the identification and treatment of the complications of cancer therapy. Minimizing the effect of the symptoms of gynecologic cancer may positively impact on patient QoL.

Fetal goiter can be the result of maternal hyperthyroidism treated with antithyroid drugs. Polyhydramnios may be the presenting symptom and can be diagnosed prenatally by sonography. We report a case of fetal goiter diagnosed at 30 weeks of gestation and fetal hypothyroidism confirmed by cordocentesis. Intra-amniotic levothyroxine was administered. Onset of preterm labor could not be prevented. The risks and benefits of intrauterine treatment of fetal goitrous hypothyroidism are discussed.

Objective: To compare the mechanism of action of raloxifene and gosereline induced shrinkage of leiomyomas via estrogen receptor, progesterone receptor, bcl-2 and p53 expression immunohistochemically., Study Design: Thirty-two premenopausal women affected by uterine leiomyomas were randomized into two equal groups. Group A was treated with gosereline (3.6 mg subcutaneous injection monthly) and group B was treated with raloxifene (60 mg daily per os) for 3 months before undergoing surgery. At entry and at the end of the treatment the leiomyoma volume was measured ultrasonografically and the volume change was calculated. Immunohistochemical detection of estrogen receptor (ER), progesterone receptor (PR), bcl-2 and p53 were performed on leiomyoma tissue samples from group A, group B and the matched-control group. H-scores for ER, PR, bcl-2 and p53 were calculated. The mean volume changes of leiomyomas and immunohistochemical H-score differences of ER, PR, bcl-2 and p53 were compared between groups., Results: The leiomyoma volume decreased significantly after treatment in gosereline group from baseline of 65 cm(3) to 35 cm(3), and in raloxifene group from 68 cm(3) to 50 cm(3), p<0.05. The difference between the before and after treatment leiomyoma volumes between the two treatments was not statistically significant. H-score of ER expression was significantly lower in gosereline group compared to control group (54.4 versus 113.2, p = 0.001), whereas H-score of PR expression was significantly lower with both gosereline and raloxifene groups compared to control group (64.8 for gosereline versus 94.6 for control, 73.6 for raloxifene versus 94.6 for control, p = 0.001). The bcl-2 expression was higher in both gosereline and raloxifene groups compared to control group (173.7 for gosereline versus 94.7 for control, 179.7 for raloxifene versus 94.7 for control, p = 0.001). The p53 expression was only lower with gosereline than the control group (169.4 versus 205.6, p = 0.001), whereas there was no significant change between the raloxifene group and the control group (201.9 versus 205.6) (p>0.05)., Conclusion: Raloxifene was as effective as gosereline in reducing leiomyoma volumes. Decreased PR expression may be a mechanism for tumor growth reduction in raloxifene treatment. In both treatment modalities, the mechanism of shrinkage of leiomyomas could not be increased apoptosis mediated by bcl-2 and p53 expression and should be investigated by further studies.

Aim: The postmenopausal period is associated with increased risk for coronary atherosclerosis, and the effect of hormone replacement therapy in reducing this risk is controversial. Previous studies reported that nitric oxide synthetase (NOS) level might be important for the development of atherosclerosis, but no study has shown the interaction between hormone replacement therapy and endothelial NOS and inducible NOS intensity on coronary arteries yet. Our goal was to find out the immunostaining intensity of endothelial NOS and inducible NOS in ovariectomized rats which received oestradiol and norethisterone treatment., Methods: We performed bilateral ovariectomy in 15, female, 90-day-old Wistar rats with an average weight of 250 grams. After waiting for 4 weeks for the menopausal state, they were divided into 3 groups to receive either placebo, 0.1 mg/day 17-beta-oestradiol (group E2), or 0.1 mg/day 17-beta-oestradiol + 0.1 mg/day norethisterone acetate (group E2-NETA) for 5 weeks. Another group included 5, normal, adult, female intact rats and served as controls. At the end of the treatment, all rats were sacrificed and coronary arteries were stained with inducible NOS and endothelial NOS polyclonal antibodies using streptavidin-biotin technique., Results: The immunostaining of inducible NOS was prominent in perivascular connective tissue of the ovariectomized group but not in the control group. The inducible NOS immunostaining immunoreactivity was not detected in either treated groups. Immunostaining intensity of endothelial NOS did not differ in any 4 groups with similar staining., Conclusion: The present findings indicate that hormone replacement therapy down-regulates iNOS expression in coronary arteries of ovariectomized rats, and reduced iNOS may likely be involved in estrogen's beneficial effects.

Introduction: Dilatation of the fetal intra-abdominal umbilical vein is a rare entity. It is unclear whether prenatally diagnosed umbilical vein dilatation is associated with an increased risk of fetal anomalies or poor perinatal outcome. Umbilical artery waveform notching may be a predictor of cord abnormalities. It seems reasonable following the baby closely after the diagnosis of both conditions., Case Report and Discussion: We present here a new case diagnosed by ultrasonography at 30 weeks of gestation with normal fetal outcome and discuss the clinical features and the management of these rare abnormalities.

In premenopausal women ovaries are the major sites of estrogen production, while in postmenopausal women estrogen is produced by aromatization of ovarian and adrenal androgens in extragonadal sites, mostly in adipose tissue. Aromatase is a cytochrome P450 hemoprotein-containing enzyme complex that catalyzes the rate-limiting step in the conversion of androstenedione and testosterone to estrone and estradiol (E2). Aromatase inhibitors (AIs) have been developed primarily for use in either natural or surgical postmenopausal patients. In premenopausal women, the ovary can overcome the estrogen blockade by reflex increments of luteinizing hormone (LH) and follicle stimulating hormone (FSH), so AIs must be combined with a gonadotropin releasing hormone (GnRH) agonist to prevent the reflex LH and FSH increments. In advanced hormone-dependent breast cancer treatment, AIs have been shown to be superior to tamoxifen. Preliminary evidence also suggests superiority in the adjuvant, neoadjuvant settings and also for breast cancer prevention. AIs have been used in infertility and can increase ovulation rate. Reducing FSH dose, estrogen levels, improving response to FSH, implantation rates, and developing multiple follicles that can be used in in vitro maturation procedures are potential areas that AIs might be used in in assisted reproductive technologies (ART), besides simple ovulation induction. AIs are reported to be successful in treatment of endometriosis, an estrogen-dependent process. The use of AIs in gynecomastia, puberte precox, leiomyoma uteri, some estrogen-dependent cancers (ovarian), endometrial cancer and male infertility are reported; some of the results are promising but more clinical trials are needed. AIs are predicted to become the gold standard in the treatment of estrogen-dependent diseases in reproductive medicine in the near future.

Objective: The goal of this study was to search the effect of hormone replacement therapy (HRT) on tear function changes in postmenopausal women., Methods: Following initial ophtalmic evaluation and tear sample collection, the subjects were given daily 0.625 mg conjugated estrogen, and either continuous combined or cyclic 5 mg medroxyprogesterone acetate was added. Eye examination included visual acuity, slit-lamp examination, fundus examination, tonometry, Schirmer's test, and break up time (BUT) evaluation. Six months later, control examination was done and repeat tear samples were obtained. Tear immune globulin A (IgA) and lysozyme levels were measured by gel electrophoresis. The pictures of the bands were evaluated by digital image analysis with Scion Image program., Results: Conjunctival vascular congestion, laxity and corneal desquamation did not change before and after HRT (P>0.05). A significant improvement was noted in meibomian gland inflammation (P=0.034). We have not observed any significant difference in burning, foreign body sensation, and tearing (P>0.05). In addition, no significant difference was noted in BUT (P=0.370) and Schirmer's test values (P=0.271). Though both lysozyme and IgA levels were elevated following the therapy, only IgA levels increased significantly (P=0.04)., Conclusion: HRT decreased meibomian gland inflammation and increased tear lysozyme and IgA levels in postmenopausal women.

Insulin plays a major role in polycystic ovary syndrome (PCOS). Insulin resistance and resultant hyperinsulinemia stimulate both the ovary and adrenal to produce androgens. Oral antidiabetic agents have been used to alleviate the symptoms and to induce ovulation in women with PCOS. This review focuses on the relation between insulin and PCOS and discusses the use of oral antidiabetic agents.

Objective: The goal of this study was to search the effects of two different doses of tibolone on endometrial IGF-1 and IGFBP-1 levels in ovariectomized rats., Methods: Eighteen adult, female, 80-90-days-old, Wistar rats with an average weight of 250 g underwent bilateral ovariectomy under general anesthesia. After waiting for 4 weeks, they were randomized into three groups to receive either oral tibolone in two different doses or placebo. The treatment was continued for 5 weeks, and then the rats were sacrificed and the endometria were analyzed., Results: Low columnar epithelium of the endometrial surface, longer epithelium and stratified squamous epithelium were seen in the control, low-dose and high-dose groups, respectively. The staining intensity of IGF-1 was mild in control, and moderate in both treatment groups, the difference between control the treatment groups was significant (P=0.015 for group L, and P=0.03 for group H). The staining intensity of IGFBP-1 was moderate in control, and strong in groups L and H. Again the difference was significant between control and both treatment groups (P=0.039 for grup L, and P=0.03 for group H). No significant difference was noted between each treatment group for both IGF-1 and IGFBP-1., Conclusion: Tibolone caused histological changes in endometrium and stimulated IGF-1 and IGFBP-1 staining. Both low and high dose treatments led to moderate and strong staining intensities for IGF-1 and IGFBP-1, respectively. The strong staining intensity of IGFBP-1 is likely due to the progestagenic effect of tibolone.

The aim of this study was to compare endometrial leukemia inhibitory factor (LIF) levels in spontaneous and clomiphene citrate (CC)-induced cycles of patients with unexplained infertility. The patients were followed in two consecutive cycles. Endometrial samples were obtained 7 days after ultrasonographic evidence that ovulation has occurred during the spontaneous cycle, then the patients were induced with CC from day 5 to day 9 during the subsequent cycle with 50 mg/day, and ovulation monitoring and endometrial biopsy were performed in the same manner. The samples were obtained using a Pipelle biopsy device without using local anesthesia, and kept in formaldehyde solution until the day of measurement. Then they were homogenized in phosphate buffered distilled water, and LIF levels were detected in the homogenized fluid by ELISA method. Endometrial LIF levels were 470 +/- 52 and 501 +/- 45 pg/1 gram wet tissue in spontaneous and CC-induced cycles respectively, revealing no significant difference. Ovulation induction with CC did not adversely affect endometrial LIF levels.

The objective of the study was to determine the changes in the plasma activities of protein C and protein S that occur during normal pregnancy In this prospective cross-sectional study, plasma activities of protein C and protein S were measured in 32 normal pregnant women in the first, second and third trimester and 6 weeks after delivery There was a significant fall in protein C and protein S activities during normal pregnancy compared with the post-puerperal period. The activities of protein C and protein S also gradually decreased throughout pregnancy (p < 0.01). Increasing plasma volume during normal pregnancy and its dilutional effect might play some role in the low activities of protein S observed. The normal falls in protein S and protein C activities make it difficult to diagnose protein S and C deficiency during pregnancy. Based on our findings, if a woman has a thromboembolic event during pregnancy, testing for a definitive diagnosis of protein C or protein S deficiency or functional failure should be delayed until at least 6 weeks postpartum.
