Adnexal masses and pregnancy: a single-center experience of 9 years.

PURPOSE: This study aims to analyze the experience of a tertiary health center about the management of adnexal masses that have been diagnosed during pregnancy or detected accidentally during cesarean delivery. METHODS: This is a retrospective review of 160 women who underwent concurrent surgery for adnexal mass during cesarean section, 24 women who delivered vaginally and subsequently had surgery due to the prenatal diagnosis of adnexal mass and 10 women who underwent surgery for adnexal mass during pregnancy. Corresponding to the delivery and surgery times, 200 women who had no diagnosis of pregnancy-associated adnexal mass served as controls. RESULTS: The women in the control group and study groups had statistically similar gestational age at delivery, birth weight and preterm delivery (p > 0.05 for all). Miscarriage was significantly more frequent in women undergoing surgery for adnexal mass during pregnancy (p = 0.001). The women who had surgery for adnexal mass during pregnancy, at the time of cesarean section and following delivery were statistically similar with respect to surgery type and histopathological diagnosis (p > 0.05 for both). Malignancy was detected in none of the patients who underwent surgery for adnexal mass during pregnancy. Acute abdomen was the indication for the emergency surgery in six patients (3.5%) who had surgery for adnexal mass during pregnancy. Four patients (2.4%) had surgery for adnexal mass during pregnancy due to the high index of suspicion for malignancy. CONCLUSION: The risk of malignancy was relatively lower in this cohort of adnexal masses detected during pregnancy and cesarean delivery. Surgical management of adnexal masses should be postponed to postpartum period as such management leads to an increased risk of miscarriage. Unless there is a need for emergent surgery or cancer staging, vaginal delivery should be encouraged in women diagnosed with adnexal mass during pregnancy.

Complementary Approaches in Fetal Genetic Diagnosis: Decision-Making Process and Alternative Choices for Clinicians in a Secondary Health Care Institution.

OBJECTIVES: The aim of this study was to determine indications of invasive, genetic results of conventional karyotyping and chromosomal microarray analysis and culture failure rates to discuss possible solution options and guide our clinical choices. MATERIALS AND METHODS: Fetal samples were analyzed by conventional karyotyping, array comparative genomic hybridization, fluorescence in situ hybridization. RESULTS: Failure rates of chorionic villus sampling (CVS) and amniocentesis were as follows, respectively: 4.5% and 0.4%. The rates of abnormal genetic results in fetuses with only thickened nuchal translucency and thickened nuchal translucency + USG abnormality were %4.2 and %40, respectively. CONCLUSIONS: Abnormal genetic results showed a significant increase in cases of thickened nuchal translucency accompanied by USG abnormalities. Although culture failure rates in the CVS were higher, none of the cases remained inconclusive. Centers with prenatal invasive genetic diagnosis should offer a wide spectrum of genetic tests by medical genetics specialists.

Nifedipine increases fetoplacental perfusion.

AIM: Our aim is to evaluate the effect of nifedipine on fetoplacental hemodynamic parameters. METHODS: A retrospective study was conducted at a tertiary center with 30 patients for whom nifedipine treatment was used as a tocolytic therapy for preterm labor. Initiation of this treatment was at 31.6±2.5 weeks of gestation. We combined the pulse Doppler imaging parameters with grayscale imaging via the Bernoulli theorem, which is called the "continuity equation", to get the fetoplacental perfusion (FPP). Evaluated parameters were the resistance index (RI), the pulsatility index (PI), systole/diastole ratios (S/D), the velocity-time integral of the umbilical artery (VTI), the radius of the umbilical artery, the peak systolic velocity and the mean pressure gradient in the umbilical artery. From these parameters, the FPP was acquired. RESULTS: We found that the RI, the PI and the S/D ratio did not change after treatment with nifedipine. The mean pressure gradient, the VTI and the peak systolic velocity increased after treatment with nifedipine. Nifedipine increases FPP from 166±73.81 beat.cm3/min to 220±83.3 beat.cm3/min. DISCUSSION: Although nifedipine had no effect on the PI, the RI or the S/D, it increased the mean pressure gradient, the VTI and FPP.

A new mathematical formula to predict the foetal weight in twin pregnancies: A comparison of it with 19 different formulas.

One hundred and seventy-two twin-pregnant patients were enrolled. The estimated foetal weight was calculated using 19 different formulas. Ong's formula (0.954 (95%CI = 0.938/0.966)), which was designed specifically for twins, produced the highest Cronbach's alpha value followed by Hadlock II (0.952 (95%CI = 0.935/0.965)), Hadlock I (0.952 (95%CI = 0.935/0.964)), Hadlock III (0.952 (95%CI = 0.935/0.964)), Hadlock IV (0.952 (95%CI = 0.935/0.964)) and our formula (0.952 (95%CI = 0.935/0.964)), which produced the same Cronbach's alpha values for twin A. For twin B, our formula produced the highest Cronbach's alpha value (0.961 (95%CI = 0.948/0.972) followed by Hadlock II (0.960 (95%CI = 0.946/0.971)), Hadlock I (0.960 (95%CI = 0.946/0.970)), Hadlock III (0.960 (95%CI = 0.946/0.970)) and Hadlock IV (0.960 (95%CI = 0.946/0.970)). In conclusion, our formula (AC, FL) performed well in predicting the foetal weights in twin pregnancies (>24 weeks) in our study. However, it should be tested in other populations. Hadlock II (AC, FL) produced a comparable performance to Hadlock I (BPD, HC, AC, FL), Hadlock III (BPD, AC, FL) and Hadlock IV (HC, AC, FL). Hadlock II may be preferable in twin pregnancies since it is based on AC and FL only.

To what extent do the presentation of fetus, amniotic fluid index and fetal weight at term affect the cardiac axis?

OBJECTIVE: To analyse the change in cardiac axis with advancing gestational age and the factors that may affect it. METHODS: 45 healthy pregnant women in 20th weeks of gestation were enrolled to the study. The cardiac axis was noted for each participant. The same group was once more assessed at term and the change in cardiac axis was calculated with the difference of cardiac axis at term and the 20th gestational weeks. Change in cardiac axis with advancing gestational weeks and factors that may affect it such as amniotic fluid index (AFI), estimated fetal weight (EFW) at term, actual birth weight and presentation of the fetus at term were evaluated. RESULTS: The median of ages was 28.0 (IQR=12.0)years within a range of 18-39years. The median of change in cardiac axis was 11.0 (IQR=9.0) degrees within a range of 3.0-47.0 degrees. The change in cardiac axis in regard to the fetal presenting part was 11.0 (IQR=8.0) degrees in vertex presentation and 23.50 (IQR=21.0) degrees in breech presentation. 81.1% of the variation in change in cardiac axis was found to be due to the actual birth weight and fetal presentation, with each 100g increase in actual birth weight leads to an increase of 0.375 degrees in cardiac axis. CONCLUSION: EFW at term, presentation of the fetus and the actual birth weight were all found to be significant in predicting the change in cardiac axis, but not AFI. These findings may have future potential value in evaluating electrocardiogram (ECG), especially of pregnants with extremes of left axis deviation (polyhydramnios, large fetus or breech presentation). Clinicians should be cautious during the interpretation of the ECG in pregnants, especially in those with extremes of left axis deviation because of either polyhydramnios, large fetus or breech presentation.

Obstetric outcomes of isolated oligohydramnios during early-term, full-term and late-term periods and determination of optimal timing of delivery.

AIM: Our aim was to evaluate the obstetric outcomes of isolated oligohydramnios during the early-term, full-term, and late-term periods, and to determine the optimal timing of delivery. METHODS: A retrospective study was performed at a tertiary center. Isolated oligohydramnios cases were divided into early-term, full-term, and late-term groups. Evaluated outcomes were fetal birthweight, 5-min Apgar score < 7, meconium-stained amniotic fluid, neonatal intensive care unit admission, transient tachypnea of newborn (TTN), requirement of ventilator, newborn jaundice, mode of delivery, induction of labor, and undiagnosed small-for-gestational-age fetus before delivery. Composite outcome was defined as perinatal outcomes taken together (neonatal intensive care unit admission, TTN, requirement of ventilator, and newborn jaundice). RESULTS: The study period included 1213 cases of term isolated oligohydramnios. Within this cohort there were 347 early-term, 781 full-term and 85 late-term patients. The cesarean rate and the rate of newborn jaundice were higher in early-term cases (37.8% and 3.5%, respectively) than in full-term cases (30.1% and 0.9%, respectively). Meconium-stained amniotic fluid was higher in late-term than full-term cases. Timing of delivery did not affect occurrence of TTN, 5-min Apgar score < 7, ventilator requirement, or composite outcome. In total, 15-17% of isolated oligohydramnios cases involved undetected small-for-gestational-age fetuses. CONCLUSION: As this study was not a randomized controlled trial, a decisive conclusion may not be possible. However, until well-designed controlled studies are conducted, expectant management may be appropriate up to the full-term period and induction of labor may be appropriate management when the full-term period is reached.

Risk factors for clavicle fracture concurrent with brachial plexus injury.

PURPOSE: The aim of this study was to evaluate the risk factors for clavicle fracture concurrent with brachial plexus injuries. METHODS: A retrospective study was conducted at a tertiary centre. The hospital records of 62,288 vaginal deliveries were evaluated retrospectively. There were 35 cases of brachial plexus injury. Of these patients, nine had brachial plexus injuries with clavicle fracture and 26 without clavicle fracture. The analysed risk factors for clavicle fracture concurrent with brachial plexus injury were gestational diabetes, labour induction and augmentation, prolonged second stage of labour, estimated foetal weight above 4000 g, birth weight above 4000 g, risky working hours, and the requirement of manoeuvres to free the impacted shoulder from behind the symphysis pubis. RESULTS: Labour augmentation with oxytocin increased the risk of clavicle fracture in cases of brachial plexus injury (OR 6.67; 95% CI 1.26-35.03). A birth weight higher than 4000 g also increased the risk of clavicle fracture. Risky working hours, gestational diabetes, estimated foetal weight higher than 4000 g, and requirement of shoulder dystocia manoeuvres did not increase the risk of clavicle fracture. CONCLUSIONS: Labour augmentation and actual birth weight higher than 4000 g were identified as risk factors for clavicle fracture in cases of brachial plexus injury.

Intrapartum, postpartum characteristics and early neonatal outcomes of idiopathic polyhydramnios.

This paper investigates the effect of idiopathic polyhydramnios on the intrapartum and postpartum characteristics of labour and early neonatal outcomes. In this study, intrapartum and early neonatal outcomes of 207 women with idiopathic polyhydramnios and 336 matched healthy pregnant patients were evaluated. In the case of idiopathic polyhydramnios, the active phase of labour became longer when compared to the control group (5.76 ± 3.56 h vs. 4.38 ± 2.8 h, p: 001). The risk of preterm birth (OR 5.23; 95% CI: 2.04-13.42) and caesarean section (OR 2.26; 95% CI: 1.56-3.28) was higher in women with IP. Patients with IP had a higher rate of transcient tachypnoea of the newborn (TTN), newborn resuscitation, admission to neonatal intensive care unit (NICU), ventilator requirement, newborn jaundice, newborn hypoglycaemia and structural anomalies. IP did not cause any appreciable maternal risk during the intrapartum or postpartum periods. However, neonatal morbidity and post-natal anomaly rates were higher in the case of IP.

Effects of Surgical Anatomical Correction of Pelvic Anterior Compartment Defect on Lower Urinary Tract Symptoms.

OBJECTIVE: To evaluate the effects of surgical anatomical correction on lower urinary tract symptoms (LUTS) in patients with a pelvic anterior compartment defect (PACD). METHODS: This prospective study was carried out on 30 women who had stage II-IV PACD. The women were questioned regarding LUTS symptoms such as urgency, urge incontinence, frequency, hesitancy, abnormal emptying, nocturia and dysuria pre and postoperatively. After a 7-month follow up, the comparison of LUTS symptoms with respect to their healing, existence or de novo appearance was performed using the McNemar and Bowner and Wilcoxon signed-rank tests. RESULTS: For the repair of ACD, 15, 8 and 7 women were operated on using site-specific surgery, transvaginal mesh placement and anterior colporrhaphy, respectively. Surgery has significantly improved the LUTS: urgency (100 vs 26.7%, urge incontinence (70 vs 16.7%), frequency (76.7 vs 13.3%), abnormal emptying (56.7 vs 10%), hesitancy (30 vs 6.7%), nocturia (83.3 vs 60%) and dysuria (30 vs 6.7%). The differences were statistically significant (P < 0.05). CONCLUSIONS: The correctional surgery on anterior compartment defects not only maintains the anatomy but also significantly heals the LUTS.

The Effect of the Amniotic Fluid Index on the Accuracy of Ultrasonographic-Estimated Fetal Weight.

BACKGROUND: Fetal weight estimation is one of the most important aspects of antenatal care. The effects of amniotic fluid volume on the accuracy of estimated fetal weight (EFW) depend on the amount of fluid, in particular whether it is polyhydramnios or oligohydramnios. Previous studies have reported conflicting results of the effects of amniotic fluid volume on EFW accuracy. AIM: The aim of the study was to evaluate the effects of isolated oligohydramnios cases and polyhydramnios on the accuracy of EFW. MATERIALS AND METHODS: A retrospective study was conducted at a tertiary center. The study groups consisted of 1069 term isolated oligohydramnios cases, 182 term isolated polyhydramnios cases, and 392 term-matched cases with a normal volume of amniotic fluid. Estimated fetal weight error was determined and expressed in terms of systematic error, calculated from mean percentage error and random error. RESULTS: The systematic error did not differ significantly between polyhydramnios and oligohydramnios cases (-3.60 [8.94%] vs -2.73 [9.7%]). The random error was 8.94% in polyhydramnios cases and 9.7% in oligohydramnios cases. The overestimation rate was 63.6% in polyhydramnios cases and 66.3% in oligohydramnios cases. CONCLUSIONS: There were no significant differences in the accuracy of EFW between oligohydramnios and polyhydramnios. However, there was a tendency for overestimation in both types of cases.

The significance of anthropometric and endocrine parameters in ovulation induction with clomiphene citrate in women with polycystic ovary syndrome.

OBJECTIVES: To investigate factors associated with the response to ovarian stimulation in patients with polycystic ovary syndrome. Methods: The records of patients with polycystic ovary syndrome and infertility who underwent ovulation induction with clomiphene citrate were reviwed between January 2011 and December 2014 in Etlik Zübeyde Hanim Women's Health Training and Research Hospital Ankara, Turkey. The anthropometric and endocrine factors of patients who were resistant to treatment at a dose of 150 mg/day (n=84) were compared with those who responded with growth of at least one graaffian follicle at a dose of 50 mg/day (n=342). Results: Of the parameters examined, body mass index, luteinizing hormone level, and luteinizing hormone/follicle stimulating hormone ratio were significantly higher in the clomiphene citrate-resistant group compared with the responsive group. Conclusion: Reproductive treatment in patients with polycystic ovary syndrome show different outcomes. Significantly higher body mass index, luteinizing hormone level, and luteinizing hormone/follicle stimulating hormone ratio observed in clomiphene citrate resistant group can be a possible explanation for this impedance.

Obstetric outcome of second trimester antenatal bleeding.

OBJECTIVE: To evaluate the clinical significance of vaginal bleeding in pregnant women between 14th and 22th gestational weeks. METHODS: This retrospective case-control study was conducted between September 2010 and December 2013. Two-hundred nineteen pregnant women with vaginal bleeding between 14th and 22th gestational weeks were compared with 325 pregnant women without vaginal bleeding for their maternal and early neonatal outcomes. RESULTS: Mean gestational age and birth weight of study group were significantly different from those of the control group respectively (37.9 ± 2.8 versus 38.9 ± 1.4 and 3071 ± 710 versus 3349 ± 446 for groups p < 0.001). Vaginal bleeding between 14th and 22th gestational weeks had increased risk of having preterm birth (PB) and preterm premature rupture of membranes (PPROM) (OR: 10.8, 95% CI: [4.5-26.1]; OR: 12.0, 95% CI: [3.5-40.6], respectively). Gestational diabetes mellitus (GDM) and polyhydramnios ratio in the study group was significantly higher than the control respectively (4.1% versus 1.2%, p = 0.031; 1.9% versus 0%, p = 0.025). CONCLUSION: Pregnant women with vaginal bleeding was a significantly risk factor for PB, PPROM, GDM, and polyhydramnios. Consequently, these pregnancies should be closely followed up for maternal and fetus complications.

The effect of serum and follicular fluid anti-Mullerian hormone level on the number of oocytes retrieved and rate of fertilization and clinical pregnancy.

OBJECTIVE: The objective of this study was to evaluate the relationship between oocyte yield, fertilization, and clinical pregnancy (CP), and anti-Mullerian hormone (AMH) level in serum and follicular fluid during in vitro fertilization treatment. METHODS: Forty-four infertile women who underwent IVF treatment using multiagonist protocol were included in this study. Baseline level of AMH in serum and follicular fluid was measured on third day of menstrual cycle. AMH level in serum and follicular fluid was then measured again on day of oocyte pick-up. Pearson correlation and binary regression tests were used for statistical analysis. For Type 1 error, p=5% was selected as cut-off value for statistical significance. RESULTS: Serum AMH level was positively correlated with total number of oocytes retrieved and rate of fertilization and CP (r=0.397, p=0.008; r=0.401, p=0.007; and r=0.382, p=0.011, respectively). There was significantly negative correlation between serum level of follicle-stimulating hormone (FSH) and fertilization rate (r=-0.320; p=0.034), as well as serum FSH level and CP rate (r=-0.308; p=0.042). There were no significant correlations between AMH level in follicular fluid and IVF treatment outcomes. CONCLUSION: Serum AMH levels may be more reliable for prediction of total number of oocytes retrieved and rate of fertilization and CP than AMH levels in follicular fluid.

Predictivity of mean platelet volume in severe preeclamptic women.

INTRODUCTION: To evaluate the predictive and clinical utilization of the mean platelet volume (MPV) in severe preeclamptic women. MPV is known as platelet size and associated with platelet activation or new platelet synthesis. Platelet count is decreased by vascular endothelial damage in cases of severe preeclampsia. It leads to increased turnover of platelets. METHODS: The severe preeclamptic women with and without preeclampsia during pregnancy were divided into subgroups depending on the gestational birth week early, (<34), late (34-37) preterm birth and term (≥37) gestational weeks. Their MPV was measured 24 hours prior to birth and compared with all subgroups according to the gestational week. RESULT: The study subgroups were performed from early (n = 87), late (n = 48) preterm and term (n = 76) birth with severe preeclampsia, whereas early (n = 69), late (n = 63) and term (n = 228) without gestational hypertensive disorders were recruited in the control subgroups. The MPV of the early, late preterm and term preeclamptic subgroups was statistically higher than that of the control subgroups (9.4 ± 1.3fL vs 8.6 ± 1.2 fL, p < 0.001; 9.5 ± 1.0 fL vs 8.5 ± 0.9 fL, p < 0.001 and 10.2 ± 1.1 fL vs 8.9 ± 1.2 fL, p < 0.001), whereas the mean platelet count of all the study subgroups was significantly lower (237.3 ± 81.3 × 109 /L, 270.0 ± 83.9 × 109/L, p = 0.015; 232.3 ± 80.1 × 109/L vs 268.8 ± 92.7 × 109/L, p < 0.001 and 221.8 ± 70.3.9 × 109/L vs 232.9 ± 82.3 × 109/L, p = 0.03). The sensitivity and specificity of the cut-off MPV for all the subgroups were each less than 80%. CONCLUSION: The MPV may be a predictive marker of severe preeclampsia.

Influence of threatened miscarriage on pregnancy and early postpartum period: a case-control report.

OBJECTIVE: To evaluate the influence of threatened miscarriage on obstetric complications during pregnancy and early postpartum period. METHODS: In this case-control study, hospital records of 12,050 first-trimester patients between January 2011 and December 2012 at the Research and Educational Hospital in Ankara, Turkey, were used. Of the 12,050 patients, 481 threatened miscarriage patients were evaluated. The control group was formed by age- and body mass index-matched cases without first trimester bleeding. Abortion, intrauterine foetal demise, preterm birth, preeclampsia, antenatal haematoma, uterine atony placental abruption and low birth-weights were compared between the study and the control group. RESULTS: When compared with the control group, the risk of having a preterm birth (p = 0.014; OR: 1.95; 95% CI: 1.15-3.24), low-birth-weight infant (p = 0.001; OR: 2.33; 95% CI: 1.45-3.83) and abortion (p = 0.00; OR: 2.55; 95% CI: 1.62-3.91) increased in cases of threatened miscarriage. However, the risk of uterine atony was decreased (p = 0.006; OR: 0.09; 95% CI: 0.12-0.7) in the threatened miscarriage group when compared with the control group. Threatened miscarriage did not increase the risk of placenta praevia, placental abruption or intrauterine foetal demise. CONCLUSION: Increased complications after threatened miscarriage is probably due to the persistence of a triggering mechanism. As preterm birth and abortion rate increased, whilst uterine atony rate decreased, one of the mechanisms causing threatened miscarriage might be increased uterine contractility.
