Fetal cloacal dysgenesis sequence presented with first trimester megacystis and associated umbilical cord abnormalities.

Cloacal dysgenesis sequence occurs as a result of complete developmental failure of the urorectal septum. Typically, the sequence is featured by a smooth perineum, without any urethral, genital or anal openings. Its clinical manifestation differs throughout gestation. We report an interesting case of first trimester megacystis with associated umbilical cord abnormalities in a female fetus having cloacal dysgenesis sequence. This rare association reflecting high urinary pressure should first suggest urethral atresia. Our case highlights the importance of routine inspection of umbilical cord in the workup of early megacystis in terms of both etiology and fetal diagnosis.

Can myometrial thickness/cervical length ratio predict preterm delivery in singleton pregnancies with threatened preterm labor? A prospective study.

OBJECTIVE: To investigate whether myometrial thickness (MT) to cervical length (CL) ratio could be used in the prediction of preterm birth (PTB) in singleton pregnancies presented with threatened preterm labor (TPL). METHODS: After 48 h of successful tocolysis, MT was measured transabdominally from the fundal, mid-anterior walls and the lower uterine segment (LUS) in 46 pregnancies presented with TPL. MT measurements were divided into CL, individually. The main outcome was PTB before 37 weeks of gestation. RESULTS: The patients were divided into two groups as women delivered ≥ 37 weeks (38.68 ± 1.01 weeks) (n = 25) and those delivered < 37 weeks (34.28 ± 2.53 weeks) (n = 21). The mean ± SD CL in the preterm delivery group was significantly shorter than the term delivery group (23.77 ± 9.23 vs 29.91 ± 7.03 mm, p < 0.05). Fundal, mid-anterior or LUS MT values were similar in both groups. However, in those who delivered preterm, the ratios of fundal MT-to-CL (p = 0.026) and mid-anterior MT-to-CL (p = 0.0085) were significantly different compared to those delivered at term. The optimal cutoff values for CL, fundal MT-to-CL and mid-anterior MT-to-CL ratios in predicting PTB were calculated as 31.1 mm, 0.19 and 0.20, respectively. Fundal MT-to-CL ratio predicted preterm delivery with 71% sensitivity, 72% specificity, 68% positive and 75% negative predictive values. For mid-anterior MT-to-CL ratio, respective values were 76, 76, 73 and 79%. CONCLUSION: Measurement of MT along with CL may offer a promising method in the management of women presented with TPL.

Effects of betamethasone on fetoplacental and maternal hemodynamics in preterm pregnancies.

OBJECTIVE: To evaluate the possible effects of prenatal steroid administration on Doppler parameters of the umbilical artery, uterine artery, middle cerebral artery, and ductus venosus, the cerebroplacental ratio, and the amniotic fluid index in preterm fetuses. METHODS: The present prospective observational study was performed at the Perinatology Department of Trakya University, Edirne, Turkey, between June 1, 2015, and September 1, 2016. It included patients with healthy singleton pregnancies who had received betamethasone at 24-34 weeks of pregnancy. Doppler parameters were measured before (0 hours) and 24, 48, and 72 hours after the administration of betamethasone (two intramuscular doses of 12 mg each, administered 24 hours apart). RESULTS: There were 68 patients included. Pairwise comparisons demonstrated that, at 72 hours after betamethasone administration, the umbilical artery resistance index (P=0.038), the middle cerebral artery systolic/diastolic velocity ratio (P=0.007), and the amniotic fluid index (P=0.017) were reduced, whereas the end-diastolic velocity of the middle cerebral artery was increased (P=0.012), compared with baseline values. CONCLUSION: Betamethasone had favorable effects on fetal cerebral circulation, with increased end-diastolic velocity in the middle cerebral artery; this could represent a positive effect on cerebral blood circulation and decreased flow resistance in the umbilical artery.

Relationship between second-trimester amniotic fluid levels of Prokineticin-1 and Matrix Metalloproteinase-2 with adverse pregnancy outcome.

To investigate the levels of Prokineticin-1 (PROK1) and matrix metalloproteinase-2 (MMP-2) in second-trimester amniotic fluid (AF). AF samples were investigated in 81 patients. AF-PROK1 and AF-MMP-2 were not significantly associated with adverse pregnancy outcomes (preeclampsia, intrauterine growth retardation, spontaneous preterm birth, gestational diabetes, gestational hypertension). AF-PROK1 levels in patients with abnormal first-trimester screening were significantly higher than those who underwent amniocentesis due to abnormal second-trimester screening tests (p = .04). AF-PROK1 or AF-MMP-2 do not have a role in the prediction of adverse pregnancy outcomes.

Long-term postpartum health problems in Turkish women: prevalence and associations with self-rated health.

OBJECTIVE: To examine the frequency of physical and emotional health problems associated with labor and their relationship with self-rated health measures. METHODS: Four hundred women were enrolled. Data collection was accomplished through the completion of a form on sociodemographic and obstetric characteristics, a questionnaire that measured the self-rated health level as well as physical health problems, and Edinburgh Postpartum Depression Scale. RESULTS: Most commonly reported health problems in the initial six-week period were fatigue (77.5%), sleep disturbance (76.0%), and dysuria (61.3%). At one-year postpartum, fatigue (33.9%), sleep disturbance (32.8%) and constipation (15.5%) were the most commonly reported complaints. Those who self-reported a "poor health" at six weeks and one year comprised of 40.0% and 19.8% of the participants, respectively. CONCLUSION: Further studies in other populations are warranted to better delineate the prevalence rates, which will provide useful data for developing policies aimed at improving postpartum care.

Tetrasomy 18p in a Twin Pregnancy with Diverse Expression in Both Fetuses.

Tetrasomy 18p, characterized by the presence of four copies of the short arm of chromosome 18, is considered to occur with the nondisjunction in meiosis II after the errors in the meiotic and early postmeiotic mitotic division in the centromere. It is accompanied by various abnormalities including congenital heart defects, lower extremity abnormalities, micrognathia, high arched palate, kyphoscoliosis, microcephaly, myelomeningocele, hernia and renal anomalies. We present the first case of a dichorionic diamniotic twin pregnancy in which both fetuses were affected by tetrasomy 18p, but with discordant morphology, detected in one twin in the first but in the other in the second trimester.

The effects of ritodrine and magnesium sulfate on maternal and fetal Doppler blood flow patterns in women with preterm labor.

OBJECTIVE: To determine the effects of ritodrine and magnesium sulfate on maternal-fetal blood flows. STUDY DESIGN: A total of 85 pregnant women between 26th and 36th weeks with preterm labor, and 83 healthy pregnant women were included. Patients in the study group were randomly assigned to receive either ritodrine (with the addition of verapamil) (n=46) or magnesium sulfate (n=39). Blood flow examinations on the umbilical artery (UA), middle cerebral artery (MCA), bilateral uterine arteries (Ut.A) and ductus venosus (DV) were performed before and 48 h after initiating therapy. RESULTS: UA pulsatility index (PI) significantly differed in women receiving tocolysis compared to controls after 48 h. DV PI increased in women receiving MgSO(4), whereas it decreased in the ritodrine and control groups. Ut.A values did not significantly change after 48 h in the groups. In women between the 26th and 32nd weeks, UA, MCA and DV PI did not significantly change after 48 h in the three groups. However, in women between the 32nd and 36th weeks UA and MCA PI significantly differed in the treatment groups compared to controls after 48 h. DV PI increased in women receiving MgSO(4), whereas it decreased in the ritodrine and control groups. CONCLUSIONS: MgSO(4) and ritodrine affect blood flow patterns after 48 h in some maternal-fetal vessels. These effects on blood flow are particularly significant in women between 32nd and 36th weeks. The effects of both drugs on fetal and maternal Doppler flows seem similar, except the increased resistance to flow in DV in women receiving MgSO(4).

The assessment of nuchal translucency and serum markers for down syndrome screening with ductus venosus Doppler measurements in the first trimester.

OBJECTIVE: The aim of the study was to improve nuchal translucency (NT) and serum marker Down syndrome (Tri21) screening methods by including fetal ductus venosus (DV) Doppler measurements. MATERIAL AND METHODS: A total of 213 pregnant women were screened consecutively by combining maternal age, fetal NT and maternal serum pregnancy associated plasma protein A (PAPP-A) and free ß-human chorionic gonadotropin (f ß-HCG) values at 11-14 weeks of gestation. Also, a DV Doppler analysis was performed for the contribution to the screening for Tri21 and other fetal anomalies or adverse pregnancy outcomes. RESULTS: Twelve fetuses had DV PI measurements above the 95th percentile and two (17%) developed intrauterine growth retardation. DV PI values negatively correlated with birth weight (p=0.013, r=0.171). Two patients had T 21 among the study group (0.9%) with abnormal biochemical screening results. In these with Tri21, the combined test risk was above the suggested limit (>1/250). PAPP-A was <0.4 MoM in 23, and f ß-HCG was >1.91 MoM in 49 patients. The rates of false positivity were 10% for PAPP-A and 22% for f ß-HCG. The sensitivity, specificity, positive and negative predictive values of the combined test was 100%, 95%, 20% and 100%, respectively. CONCLUSION: The combined test has high sensitivity and specificity for Tri21 detection. The addition of DV Doppler ultrasound in the first trimester might have the advantage of predicting some adverse pregnancy outcomes. However, in the Turkish population, further studies with larger numbers of patients will be needed to establish the usefulness of DV for the detection of Tri21 or the prediction of some major cardiac anomalies.

Do routine preoperative imaging techniques facilitate the operation in endometrial cancer?

OBJECTIVE: To assess the role of routine intravenous pyelography (IVP), rectoscopy and additional imaging techniques like computed tomography (CT) and abdominal ultrasonography (USG) for the evaluation of patients with endometrial cancer. MATERIALS AND METHODS: A total of 97 women with endometrial cancer (82 endometrioid and 15 non-endometrioid type) of all stages (Stage I = 65, II = 14, III = 13, IV = 5) were included in the study. Of these, 50 women were admitted because of postmenopausal bleeding, 24 with irregular vaginal bleeding and 7 with pain and leucorrhea, whereas the others had no complaints. Only one patient had symptoms related to the gastrointestinal system, but none for the urinary system. Preoperative CT (n = 45), IVP (n = 78), rectoscopy (n = 46), and USG or colonoscopy (n = 37) were performed on our patients. All the women had total abdominal hysterectomy and bilateral salpingo-oophorectomy, with/without pelvic (n = 81) and paraaortic (n = 34) lymphonodectomy, and omentectomy (n = 35). RESULTS: In 39 of 45 women who had CT, it had no effect on the operation and did not facilitate the operation. In two women there were pathological findings on CT and some interventions (resection and anastomosis) were performed on the gastrointestinal tract in these patients. However, CT had overcome pathological findings related with the gastrointestinal or urinary systems in four women, who needed interventions to these systems during the operation. CT was not performed on six women who needed interventions to the gastrointestinal system during the operations. Three patients had pathological findings (fissure, external compression) in rectoscopy, but only one patient had ileo-transverstomy, in which rectoscopic finding had not predicted the necessity of that procedure. Out of 78 IVP, the only finding was external compression to the bladder in 38 patients, and this finding had no contribution to the operation. Among women who had USG or colonoscopy (n = 37) performed, five had pathological findings that contributed to the extensiveness or the mode of the operations (liver nodules, polyps in the colon). CONCLUSIONS: Routine preoperative computed tomography, intravenous pyelography, rectoscopy or abdominal USG and colonoscopy have little impact on the decision and the prediction of the extensiveness of the operation.

Correlation between maternal plasma thrombomodulin and infant birth weight in hypertensive disorders of pregnancy.

OBJECTIVE: To evaluate the association between maternal plasma thrombomodulin levels and infant birth weights in pregnancy-induced hypertension. STUDY DESIGN: Plasma thrombomodulin levels were measured in 80 pregnant women living in the Trakya region of Turkey. Of these patients, 30 were with severe preeclampsia, 10 with HELLP syndrome, 10 with eclampsia, and 30 were normotensive healthy pregnant women. Plasma thrombomodulin levels were determined by the enzyme-linked immunosorbent assay method. The correlation analysis between thrombomodulin and birth weight and placental weights was done using analysis of variance and Bonferroni test (significance at P < .05). Kruskal-Wallis statistical analysis was performed in comparison of the descriptive and laboratory data (significance at P < .05). RESULTS: The plasma thrombomodulin values in hypertensive disorders in pregnancy were found to be highly correlated with the infant birth weights (P < .001). In HELLP syndrome, the highest thrombomodulin levels (94.69 + 10.41 ng/mL) were associated with the lowest infant birth weight (1509.70 + 187.55 g) in the study population. Thrombomodulin in eclampsia (81.37 + 3.59 ng/mL) showed an association with infant birth weight (2078 + 132.65 g). Although thrombomodulin levels in severe preeclampsia (67.15 + 3.72 ng/mL) were associated with the values (1748.20 + 132.62 g) in infant birth weight, thrombomodulin levels of the control group demonstrated the mean (48.06 + 2.45) with the highest infant birth weight (3228.85 + 84.83) in the total group. CONCLUSION: Elevated plasma thrombomodulin levels in hypertensive disorders of pregnancy were well correlated with related infant birth weights of these pathologies. Plasma thrombomodulin levels might point out placental vascular endothelial damage reflecting on infant birth weights.

Pregnancies complicated by adnexal masses: a case series.

INTRODUCTION: Adnexal masses>or=5 cm in diameter are rare during pregnancy. MATERIALS AND METHODS: We present our experience on six pregnant women with adnexal masses diagnosed and operated during pregnancy and/or at the time of cesarean section. RESULTS: Carefully selected cases with a unilateral mass and a solid component with normal tumor marker result can be followed until term and adnexectomy can be performed during cesarean section. On the contrary, gross adnexal masses, even with normal tumor marker levels should be operated when diagnosed, but these women might deliver small for gestational age infants. CONCLUSION: By depending upon restricted criteria according to tumor markers, ultrasound or other radiological imaging techniques, some patients with an adnexal mass carrying an important risk factor for malignancy may be overlooked.

The association of triple-marker test results with adverse pregnancy outcomes in low-risk pregnancies with healthy newborns.

OBJECTIVE: This study was designed to investigate the relationship between the second trimester maternal serum markers and adverse pregnancy outcomes in healthy newborns. MATERIALS AND METHODS: A total of 749 women who delivered in our institution with complete follow up and second-trimester triple marker test data available were included in the study. Women with multiple pregnancies, chronic diseases, diabetes mellitus, obesity, smokers and infants with chromosomal and congenital abnormalities were excluded. Maternal serum alpha-fetoprotein (AFP), human chorionic gonadotropin (HCG) and unconjugated estriol (uE(3)) values were investigated in our cohort who developed preeclampsia (n = 28), gestational diabetes (GM) (n = 69), preterm labor-birth (n = 100), oligohydramnios (n = 37) and macrosomia (n = 59) by using receiver operating characteristic (ROC) curve analysis, with chi-square and Pearson's correlation tests. RESULTS: Women with uE(3) < or = 1.26 MoM (P = 0.001, AUC = 0.666), HCG > 1.04 MoM (P = 0.032, AUC = 0.599) or AFP < or = 0.69 MoM (P = 0.049, AUC = 0.600) values significantly developed oligohydramnios. Also, macrosomic infants were observed in women who had HCG values > 0.86 MoM (P = 0.047, AUC = 0.578). Patients with HCG > 1.04 MoM (P = 0.04, AUC = 0.565) and uE(3) < or =0.88 MoM (P = 0.049, AUC = 0.571) developed GDM. HCG levels > or =2.5 or > or =3 MoM were significantly associated with the development of oligohydramnios [P = 0.005; OR = 4 (95% CI: 1.7-9.7)], [P = 0.008; OR = 4.9 (95% CI: 1.7-13.7)], respectively. When women with adverse (n = 237) and normal (n = 512) outcomes were compared there were significant differences in maternal serum AFP (1.40 +/- 0.84 vs. 1.23 +/- 0.75 MoM, P = 0.006) and uE(3) values (1.38 +/- 1.42 vs. 1.45 +/- 0.98 MoM, P = 0.001). CONCLUSIONS: Serum estriol, AFP or HCG values in triple test results may be associated with development of oligohydramnios, gestational diabetes and macrosomia in women with healthy and normal appearing fetuses.

Isolated fetal intracardiac hyperechogenic focus associated with neonatal outcome and triple test results.

OBJECTIVE: To investigate the relationship between isolated intracardiac hyperechogenic focus (IHF) in the mid trimester of pregnancy with neonatal outcomes and triple test results. MATERIALS AND METHODS: The study included low-risk pregnant women who came for routine follow-up to our antenatal clinic between years 2000 and 2005. A detailed structural survey by ultrasound (USG) of the fetal heart was performed on each fetus in the mid-trimester of pregnancy. All patients had mid-trimester triple tests performed between the 16th and 18th weeks' of pregnancy. We recruited a total of 40 pregnancies that had fetal IHF in the level II USG examination and a control group of 100 healthy pregnant women those which were followed-up during the same period. Twenty-nine fetuses (72.5%) had left, 8 (20%) had right whereas 3 (7.5%) had bilateral ventricular IHF. We compared the perinatal and neonatal outcomes and triple test results of the fetuses that had right and left IHF, and the controls. RESULTS: Cytogenetic amniocentesis was performed to 6 (15%) women in the study and 5 (5%) in the control group and all were normal. During follow-up IHF spontaneously disappeared in 30 fetuses [right (n: 5), left (n: 23) or bilateral (n: 2)]. We did not observe any cardiac problem in the postnatal period in all newborns. Only one infant (2.5%) in the study group was admitted to neonatal intensive care unit because of prematurity. Median delivery weeks (P = 0.023), head circumference (P = 0.013), 5-min Apgar score (P = 0.021] and apnea (P = 0.042) were significantly higher in fetuses with right IHF. Compared to the controls, median delivery weeks (P = 0.038) was significantly higher in fetuses with right IHF, but head circumference (P = 0.004), 1-min (P = 0.003) and 5-min (P < 0.001) Apgar scores were lower in fetuses with left IHF. However no difference was observed in second-trimester serum human chorionic gonadotropin (HCG), alpha-fetoprotein (AFP) and estriol (E(3)) levels, in the three groups. There was no correlation between serum HCG, AFP and E(3) levels and the presence of IHF. CONCLUSIONS: Isolated IHF in the fetal heart in the mid-trimester of pregnancy seems not associated with adverse neonatal outcome and does not correlate with triple test results.

Third trimester maternal plasma total fibronectin levels in pregnancy-induced hypertension: results of a tertiary center.

The aim of this study was to evaluate maternal plasma total fibronectin values in pregnancy-associated hypertension in women in the third trimester of pregnancy. A total of 125 pregnant women at the 24th week of gestation participated in this study. Nonpregnant normotensive women were included as control group (n = 30). Plasma samples for fibronectin were obtained at the 24th, 28th, and 32nd weeks of gestation from all pregnant patients. From this cohort, 10 patients met the criteria for the diagnosis of gestational hypertension and 15 women met the stringent requirements of preeclampsia, whereas 100 patients were normotensive later in gestation. Plasma total fibronectin levels were determined by radial immunodiffusion technique. Data were analyzed using the SPSS program. The mean plasma fibronectin levels of the pregnant women in whom gestational hypertension and preeclampsia developed were significantly higher at the 24th, 28th, and 32nd weeks in comparison to normotensive pregnant women (p < 0.001). However, throughout the period from the 24th to 32nd weeks of pregnancy, plasma total fibronectin levels did not exhibit a significant change in normotensive pregnant patients or in patients with preeclampsia and gestational hypertension. There was also no correlation between plasma fibronectin levels and gestational age, mean arterial pressure, birth weight, and 5-minute Apgar scores in all groups (p < 0.05). The elevated maternal plasma fibronectin level over 40 mg/dL is capable of predicting preeclampsia with a sensitivity of 73% and a specificity of 92%. These results suggest that serial plasma fibronectin measurements before 24 weeks' of gestation may be helpful in the early detection of preeclampsia in normotensive gravid women who are destined to become clinically preeclamptic.

Evaluation of natural coagulation inhibitor levels in various hypertensive states of pregnancy.

OBJECTIVE: To evaluate the role of natural coagulation inhibitors in various classifications of pregnancy associated hypertension in Turkish population living in Trakya region of Turkey. STUDY DESIGN: Serum uric acid levels, plasma protein C (PC), protein S (PS), antithrombin III (AT III) activities and activated protein C resistance (APCR) were measured in 80 pregnant women with hypertension (preeclampsia, n = 32; severe preeclampsia, n = 25; eclampsia, n = 14; chronic hypertension, n = 9) and 58 healthy pregnant women. Tukey and Tamhane multiple comparison tests, Kruskal-Wallis, chi2 and Fisher's exact tests were performed for comparison of means and/or medians. RESULTS: Serum uric acid levels were significantly elevated in women with preeclampsia and severe preeclampsia, but PS activity decreased in women with severe preeclampsia (33.2 +/- 18.9% versus 50.4 +/- 22.7%, p = 0.015) and chronic hypertension (29.5 +/- 14.5% versus 50.4+ /- 22.7%, p = 0.045) compared to healthy controls. There was no significant difference in APCR, and PC or AT III activity between the groups. Platelet counts were significantly lower in women with severe preeclampsia, compared to controls and women with chronic hypertension. CONCLUSION(S): Serum uric acid levels and plasma protein S activity may be useful as indices of severity of pathology in pregnancy associated hypertension.

Oral nifedipine maintenance therapy after acute intravenous tocolysis in preterm labor.

AIMS: Our aim was to evaluate the efficacy of maintenance oral nifedipine in pregnant women initially treated with intravenous ritodrine plus verapamil for preterm labor. METHODS: The study included 73 patients with preterm labor with intact membranes. Patients were randomized to receive either maintenance oral nifedipine therapy (n=37) administered 20 mg every six hours or no treatment (controls, n=36) after discontinuation of acute intravenous tocolysis. RESULTS: Compared to the control group, the mean +/- SD time gained from initiation of maintenance therapy to delivery (26.65 +/- 18.89 vs. 16.14 +/- 12.91 days, p=0.007) and the gestational age at delivery (37.03 +/- 2.06 vs. 35.1 +/- 3 weeks, p=0.003) were higher in the nifedipine maintenance therapy group. The proportion of patients who required one or more courses of subsequent intravenous therapy and perinatal outcomes were similar in the maintenance therapy and control groups. CONCLUSIONS: The gestational age and time gained from initiation of maintenance therapy to delivery were longer in women receiving oral maintenance tocolysis with nifedipine. However, maintenance therapy did not decrease the recurrence of preterm labor episodes or improve perinatal outcomes.
