Assessment of utero-cervical angle and cervical length as predictors for threatened preterm delivery in singleton pregnancies.

OBJECTIVES: The aim of this study was to evaluate the relationship between the cervix and the threat of preterm labor in singleton pregnancies between gestational weeks less than 37 and greater than 37 weeks in correlation with utero-cervical angle (UCA) and cervical length (CL) measurements. MATERIALS AND METHODS: We conducted a prospective cohort study with UCA and CL measurements in patients with threatened preterm labor (TPL). Primary outcome was differences in UCA and CL measurements in relationship to maternal characteristics and perinatal outcome between groups. Secondary outcome evaluated measurement results and influencing factors for delivery within 7 days, between 1 and 4 weeks and beyond 4 weeks. RESULTS: Overall 152 patients were divided into as study/preterm group (<37 weeks; n = 56) and the control/term group (≥37 weeks; n = 96). Mean gestational age at admission was similar in both groups (30.98 ± 2.83 vs. 30.36 ± 2.63 weeks, p = 0.149) with similar CL (33.9 ± 6.34 vs. 32.02 ± 8.88 mm, p = 0.132), but wider UCA in the preterm group (81.65 ± 16.81° vs. 99.21 ± 22.33°, p < 0.001). Multivariate logistic regression analysis for preterm delivery was significant for nulliparity and UCA measurement. The factor for delivering before 37 gestational weeks within 7 days was the gestational week at admission (p = 0.046). UCA and CL measurements were statistically significant for distinguishing patients for delivery within 7 days and beyond 4 weeks (p = 0.001 for CL and p = 0.0001 for UCA). NPV was found 92.5, 92.2, and 92.3 for UCA >105°, CL ≤30 mm, and Bishop score >3, respectively. CONCLUSION: Combined measurement of TV UCA and CL represents stronger predictors for sPTB ultrasonographically, demonstrating the uterocervical sub-segment maturation before the active onset of labor.

Successful prenatal treatment with continuous chronic maternal hyperoxygenation therapy in hypoplastic left heart in two pregnancies: Case report.

Maternal hyperoxygenation (MH) has been studied as a diagnostic tool to evaluate pulmonary vasculature and as a treatment option to improve the growth of fetal left heart in fetuses with left-sided cardiac defects. Chronic maternal hyperoxygenation (CMH) therapy leads to an improvement in fetal pulmonary blood flow resulting in an enhanced venous return to the left heart with increased gestational age. With this manipulation it is anticipated to augment blood flow directed remodeling of the left heart structures and to improve left heart growth spanning from the mitral valve to the aortic isthmus. However, there are concerns about CMH therapy with regard to fetal complications with growth restriction and fetal brain development. Now, with two successful cases we try to discuss this fetal treatment option and related concerns.

Threatened miscarriage and recurrent miscarriage: Expert opinions on progesterone therapy and treatment challenges.

It is crucial to gain a better understanding of threatened and recurrent miscarriages, including the existing knowledge and unknowns, as well as to discuss medical approaches and assess the situation. These issues are outstanding problems, causing significant physical and emotional burdens on women and their families, not only in Turkey but also worldwide. This article aims to explore the topic of miscarriages, including the implications, challenges, and potential therapeutic approaches in Turkey. Nineteen statements were presented to 6 Turkish perinatologists and obstetricians and gynecologists to evaluate the management of threatened and recurrent miscarriage and to compare the results with literature recommendations in an expert opinion meeting. Turkish perinatologists and obstetricians & gynecologists provided their responses using a 5-point Likert scale and discussed every statement. Progesterone use, particularly oral dydrogesterone, was supported by most of the experts. Opinions varied on the preference for dydrogesterone in recurrent miscarriage treatment. Experts unanimously agreed on the efficacy and safety of dydrogesterone and its recommendation in guidelines for threatened and recurrent miscarriage. Regarding progesterone therapy, vaginal progesterone was not associated with an increased rate of live births. Side effects of vaginal and oral micronized progesterone were acknowledged, and compliance with oral progesterone treatment was generally agreed upon. Dydrogesterone activity and effectiveness in threatened miscarriage received positive responses, while opinions on its effectiveness in recurrent miscarriage were divided. The loading dose of dydrogesterone and the practice of checking blood progesterone levels had different opinions among experts.This manuscript provides valuable insights in the management of threatened and recurrent miscarriages, highlighting the role of progesterone therapy, specifically dydrogesterone, and the need for adherence to relevant guidelines. Further research and a national Turkish guideline are warranted to address areas of uncertainty and optimize the management of these conditions.

Predicting previable preterm premature rupture of membranes (pPPROM) before 24 weeks: maternal and fetal/neonatal risk factors for survival.

We sought to compare maternal and neonatal risk factors in cases with previable premature rupture of membranes (pPPROM, between 14-24 weeks) for optimal counselling. Therefore, 192 pregnancies of 485 cases which met selection criteria and agreed to follow-up were retrospectively analysed. Mean gestational age at pPPROM was 20.45 weeks. Live births occurred in 171 cases, but 67 (39.2%) of them died in the neonatal period (neonatal death group) and 104 cases (60.8%) constituted surviving neonate group. Of the surviving neonates, 37 (33.7%) experienced at least one complication. Most seen maternal complications were chorioamnionitis (24.48%) and placental abruption (8.33%). Although amniotic fluid volume, length of pPPROM period, completing antibiotherapy and CRP values were significant, amniotic fluid volume and length of pPPROM showed also significance for multivariate regression analysis for maternal risk factors. Risk factors for birth were gestational age at pPPROM, gestational age at birth, new-born weight at birth, 1st and 5th minute Apgar scores, umbilical cord pH value and need for neonatal resuscitation. Furthermore, development of respiratory distress syndrome, necrotising enterocolitis, intraventricular haemorrhage and retinopathy of premature were additional risk factors for neonate. Of them, gestational age at birth, new-born weight at birth, respiratory distress syndrome and retinopathy of prematurity were also significant in multivariate regression analysis.Impact StatementWhat is already known on this subject? Management of previable premature rupture of membranes is controversial and there is no definite consensus on the approach. The factor that best predicts neonatal survival is the gestational age at birth (Deutsch et al. 2010).What do the results of this study add? Appropriate counselling for pPPROM cases is important especially during antenatal period (maternal factors) and postpartum period (neonatal factors). Maternal infection risk is increased with an increased latency period of PPROM. As the gestational age at birth increases, the survival rate increases and neonatal complication rates decrease. Other important determinants of neonatal survival and well-being are the presence of oligo-anhydramnios and latency period of previable PPROM to delivery.What are the implications of these findings for clinical practice and/or further research? Counselling the patient with previable PPROM about pregnancy complications and paediatric outcome is challenging because of the small size, different gestational age ranges, and retrospective nature of the multiple studies on this subject. The most important feature of our study was the relatively high number of patients compared to other series. Thus, we can counsel pregnant women with PPROM prior to 24 weeks of gestation about the maternal antenatal factors and neonatal postnatal factors with related outcomes and help make an informed decision regarding termination or conservative follow-up. Nevertheless, there is a need for larger multicentric prospective studies to validate our data and to establish the prognosis of previable PPROM for both mother and foetus.

Maternal serum procalcitonin levels in prediction of chorioamnionitis in women with preterm premature rupture of membranes.

INTRODUCTION: Chorioamnionitis is one of the most important maternal complications in the expectant management of patients with preterm premature rupture of membranes (PPROM). Procalcitonin (proCT), the precursor of the hormone calcitonin, is used to differentiate bacterial infections from non-bacterial ones. The objective of the study was to determine the efficacy of maternal serum procalcitonin levels in the early prediction of chorioamnionitis in women with PPROM. MATERIAL AND METHODS: The study was conducted in 76 pregnant women hospitalized due to PPROM at the maternal-fetal medicine unit of a tertiary center in Istanbul. Patients were followed up with white blood cell (WBC), C-reactive protein (CRP) and proCT levels every 2 days. The values of investigated parameters were recorded at the diagnosis of PPROM and at the time of delivery. The maximum values during the follow-up period were also recorded. RESULTS: Out of the 76 patients with PPROM, 15 (19.73%) developed clinical chorioamnionitis. No significant difference could be detected in the gravidity, parity, duration of hospitalization and gestational week at diagnosis between those patients who developed clinical chorioamnionitis and those who did not. The WBC at the time of hospital admittance and before delivery, and CRP levels before delivery were statistically higher in the chorioamnionitis group (p < 0.05). No difference in the proCT levels could be detected either at the time of hospital admittance or before delivery between the two groups. CONCLUSIONS: Maternal proCT was not found to be predictive of chorioamnionitis. However, since there are reports in the literature that contradict these results, further studies are warranted to determine the true efficacy of proCT in the prediction of clinical chorioamnionitis.

Investigation of fetal cardiac function using tissue doppler imaging in fetuses compromised by growth restriction.

OBJECTIVES: The primary aim of this study was to evaluate fetal cardiac systolic and diastolic function using the tissue Doppler technique in pregnancies with complications of fetal growth restriction (FGR) and to examine the relationship between FGR with umbilical artery Doppler parameters and fetal cardiac function in complicated pregnancies. MATERIAL AND METHODS: This study included 30 pregnant women with FGR complications and 46 pregnant women without FGR complications. Both groups were at 24-34 gestational weeks. Fetal cardiac examination was performed using pulsed Doppler and tissue Doppler imaging (TDI) in all pregnancies. In the analysis of myocardial tissue by tissue Doppler, the tracing obtained from the junction of the tricuspid valve annulus with the right ventricle was recorded by measuring the duration of the isovolumetric contraction wave (IVC), ejection time (ET), and isovolumetric relaxation time (IVR). Furthermore, we calculated the myocardial performance index (MPI) and then measured and recorded the early diastolic annular rate. RESULTS: Based on the TDI studies, the mean IVC and IVR values were significantly longer and the ET values were significantly shorter in the study group than those in the control group. The study group also had significantly longer MPI measurements. CONCLUSIONS: Because TDI is a considerably more sensitive method than cardiac sonographic evaluation using pulsed Doppler, tissue Doppler parameters facilitate the detection of cardiac dysfunction at a relatively early stage. In addition, TDI and myocardial evaluation in fetuses with FGR can be noninvasively performed in clinical practice.

A comparison of obstetric outcomes in adolescent pregnancies and adult pregnancies.

Introduction: Adolescent pregnancies are associated with adverse maternal and fetal outcomes including preeclampsia, preterm birth, and fetal growth restriction compared to adult pregnancies. The purpose of our study is to compare the incidents of obstetric outcomes between the adolescent pregnancies and adult pregnancies.Materials and methods: This retrospective case-control study was conducted between January 2013 and January 2018 at Kanuni Sultan Suleyman Research and Training Hospital, Istanbul, Turkey. The institutions' medical records were screened for women with pregnancies after 24 weeks of gestation. Women under 19 years of age were included as the adolescent group and women between the ages of 20 and 29 were included as the control group. Obstetric outcomes were compared between the groups.Results: There were 3875 adolescent pregnancies in the case group and 3875 adult pregnancies in the control group. Even after adjusting for confounders in our adolescent pregnant cohort, the odds of intrauterine growth restriction, preterm birth and premature rupture of membranes were higher than in our adult pregnant cohort. On the other hand, we found low incidents of preeclampsia and gestational diabetes mellitus in pregnant women younger than 19 years of age.Conclusions: Adolescent pregnancies should be closely followed up as they have higher preterm birth rates as well as the risk of intrauterine growth restriction.

Urinary neutrophil gelatinase-associated lipocalin is associated with preeclampsia in a cohort of Turkish women.

Purpose: We investigated the optimal cut-off level for urinary neutrophil gelatinase-associated lipocalin (NGAL) in preeclamptic patients to confirm the diagnosis. Methods: Urinary NGAL concentrations were measured by specific enzyme-linked immunosorbent assay (ELISA). Results: Patients with preeclampsia had significantly higher urinary NGAL concentrations than controls (mean: 387 ng/ml vs. 188 ng/ml, respectively; P< 0.001). Using a cutoff value 252 ng/ml for urinary NGAL to confirm diagnosis of preeclampsia, sensitivity, and specificity were 92% and 91%, respectively. Conclusion: Urinary NGAL concentrations were significantly elevated in women with preeclampsia versus normotensive controls.

Characteristics of total laparoscopic hysterectomy among women with or without previous cesarean section: retrospective analysis.

BACKGROUND: The number of hysterectomized patients with previous cesarean sections (CSs) has increased due to increasing CS rates. A previous history of CS has been demonstrated to be an important risk factor for major complications in total laparoscopic hysterectomy. The aim here was to evaluate the major complications and safety of TLH in patients with previous CS. DESIGN AND SETTING: Retrospective analysis in a tertiary-level center. METHODS: The medical records of 504 total laparoscopic hysterectomy patients operated between May 2013 and May 2017 were reviewed retrospectively. Data on age, parity, surgical indications, duration of operation, length of hospital stay, histopathological diagnosis and major intra and postoperative complications were gathered. The patients were categorized into two groups according to their CS history, namely those with and those without previous CS. Major complications were defined as the presence of lower urinary tract injury (bladder or ureter injury), enterotomy/colostomy, bowel serosal injury or vascular injury. RESULTS: There was no difference between the groups in terms of parity, duration of operation, hospital stay or pre and postoperative hemoglobin levels. The conversion rates to laparotomy in the previous CS and no CS groups were 2% and 1.7%, respectively. The rates of major complications in the previous CS and no CS groups were 5% and 1.3%, respectively, and these results did not differ significantly (P > 0.05). CONCLUSION: TLH could be performed safely in the previous CS group, since the complication rate was not different from that of the patients without previous CS.

Evaluation of cesarean scar after single- and double-layer hysterotomy closure: a prospective cross-sectional study.

BACKGROUND: We aimed to determine if there is a difference in the size of the cesarean scar defect using saline infusion sonography (SIS) performed on the postoperative third month in patients who underwent single- or double-layered unlocked closure of their uterine incision during their first cesarean delivery. METHODS: This study was conducted as a prospective cross-sectional study between February 2015 and January 2016 in patients admitted to the labour ward of the Kanuni Sultan Suleyman Training and Research Hospital who subsequently underwent their first delivery by cesarean section. Patients with a previous history of cesarean delivery, preterm pregnancies less than 34 gestational weeks, patients lost to follow-up or those who had an IUD inserted after delivery were excluded from the study. Out of the 327 patients who underwent primary cesarean delivery, 280 were included into the study. Patients were divided into two groups according to the single- (n:126) or double-layered (n:156) closure of their uterine incision. The maternal age, height, weight, obstetric and gynecologic histories, medical histories, indications for their cesarean delivery, technique of uterine closure, birth weight of the baby, duration of the cesarean delivery, need for extra suturing and transfusion were recorded. A Saline infusion sonography (SIS) was performed 3 months postoperatively to determine the presence, depth and length of the cesarean scar. The residual myometrial thickness overlying the scar defect and the fundal myometrial thickness were recorded. RESULTS: No difference was detected between the groups with respect to patient characteristics, whether the operation was elective or emergent, the type of anesthesia used, need for extra suturing, incidence of bladder injuries or uterine atony, need for blood transfusions, duration of labour or cervical dilatation and effacement between the two groups. No statistically significant difference was detected between the two groups with respect to the length and depth of the scar defect. CONCLUSION: Single- or double-layered closure of the uterus does not seem to affect the size of the uterine scar defect detected on SIS 3 months following the first cesarean delivery.

Risk factors for surgical site infection after hysterectomy.

INTRODUCTION: The aim of the study was to define the clinical and laboratory characteristics of patients who had surgical site infection (SSI) after hysterectomy. METHODOLOGY: This study was a retrospective cohort study. The patient data of 840 subjects who had undergone any type of hysterectomy and reported SSI after surgery were obtained from the archives of a tertiary referral center. The different types of hysterectomy procedures performed on these patients included total abdominal hysterectomy (TAH), laparoscopic hysterectomy (LH), and vaginal hysterectomy (VH). In addition, age, body mass index (BMI), preoperative and postoperative blood parameters, gravidity, and parity were also documented. RESULTS: TAH, LH, and VH were performed on 63.2% (n = 531), 21.6% (n = 181), and 15.2% (n = 128) of patients, respectively. Overall, SSIs were observed in 3.7% (n = 31) of all hysterectomy patients. Among them, 4.5% of TAH patients, 1.7% of LH patients, and 3.1% of VH patients had SSIs after the hysterectomy operation. Analysis of the data revealed that the patients with SSIs had significantly higher BMIs, lower preoperative hemoglobin, lower postoperative hemoglobin and hematocrit, and higher postoperative platelet counts compared to patients who did not have any SSIs. CONCLUSIONS: High BMI, blood loss during surgery, low hematocrit levels, and resulting anemia increased the incidence of SSI after hysterectomy. Among the different types of hysterectomy, LH was found to be relatively better than TAH and VH in preventing the occurrence of SSI.

The effectiveness of double incision technique in uterus preserving surgery for placenta percreta.

BACKGROUND: Placenta percreta is a life-threatening condition that places patients at risk of massive bleeding. It necessitates very complicated surgery and can result in mortality. Caesarean hysterectomy is the accepted procedure worldwide; however, recent studies discussing conservative treatment with segmental resections have been published. Foetal extraction and segmental resection can be performed through the same incision (single uterine incision) or through two different incisions (double uterine incision). In this study, we aimed to evaluate the effectiveness and results of the double incision technique. METHODS: Twenty-two patients with a diagnosis of placenta percreta who underwent conservative surgery were included. Segmental resection was performed via single incision in ten patients and double incision in twelve patients. RESULTS: There was no difference between the patients who underwent segmental resection via single and double incision in terms of age, gravida, number of previous caesarean deliveries, gestational age at delivery, or rate of elective surgeries. The operation time, transfusion requirement, intensive care unit admission, total hospitalization and success of conservative surgery were comparable between the groups. CONCLUSIONS: Based on the outcomes of our study, double uterine incision allows for the safe extraction of the foetus during uterus-preserving surgery in patients with placenta percreta without worsening the results compared to single uterine incision. TRIAL REGISTRATION: NCT02702024 , Date of registration: February 26, 2016, retrospectively registered.

Analysis of HbsAg positivity rate before and after vaccination in Turkish and Syrian refugee pregnant women.

INTRODUCTION: In this study, we aimed to investigate the vaccination rate in Turkish and Syrian pregnant women who gave birth in our hospital, research the difference before and after vaccination, compare these results with other studies conducted in our country and be beneficial to physicians in the follow up of this patient group, who we started to encounter rather frequently in recent months. METHODOLOGY: The data of pregnant women who were referred to Kanuni Sultan Suleyman Education and Research Hospital between January and December 2015 were retrospectively investigated. RESULTS: A total of 4186 pregnant women, 2158 of Syrian and 2028 of Turkish, were included in this study. The rate of hepatitis B surface antigen (HbsAg) positivity was 1.4% among all pregnant women. This value was found to be 1.8% among Turkish women and 1.1% among Syrian women. Evaluation of age distribution showed that there were 30 Turkish pregnant women born after the inclusion of vaccine into the program (1998 and later), of which one was HbsAg positive. While out of 958 Syrian women born in 1991 and later, 10 were HbsAg positive. CONCLUSION: This study shows that the surveillance of hepatitis among pregnant women, including refugees and locals is important to protect fetus and guide in planning of preventive measures such as administration of vaccines and immunoglobulins. Timely prevention may decrease morbidity and mortality caused by hepatitis viruses.

The utility of first trimester uterine artery Doppler, placental volume and PAPP-A levels alone and in combination to predict preeclampsia.

In this study, we aimed to evaluate the detection of pre-eclampsia (PE) by integrating uterine artery Doppler, placental volume, and pregnancy-associated plasma protein A (PAPP-A) levels in the first trimester. We prospectively recruited 602 women that underwent 11-13weeks' aneuploidy screening. The mean pulsatility index (PI) of the uterine arteries and the placental volume were measured by ultrasonography. Measurement of PAPP-A levels has been performed at the same day of ultrasonographic examinations. The 90th percentile of uterine artery PI and the 10th percentile of placental volume and PAPP-A levels were used as cut-offs. Uterine artery PI, placental volume, and PAPP-A levels had similar sensitivities in predicting PE (53.66%, 63.41%, and 70.73%, respectively). Use of the parameters in combination had better sensitivity. If one parameter was positive, the sensitivity was 92.68% with 85.20% specificity. If at least two parameters were positive, the sensitivity was 85.37% with 98.89% specificity. In conclusion, the combination of increased PI of uterine artery with low placental volume and low PAPP-A levels in the first trimester achieved better results than either test alone in the prediction of PE.

Suction curettage as first line treatment in cases with cesarean scar pregnancy: feasibility and effectiveness in early pregnancy.

OBJECTIVE: A cesarean scar pregnancy (CSP) is an extremely rare form of an ectopic pregnancy, which is defined as the localization of a fertilized ovum surrounded by uterine muscular fiber and scar tissue. The objective of this study was to discuss the management options for CSPs in a singleton center. In the current study, we discussed the current management options for CSPs based on our 6 years of experience. MATERIAL AND METHODS: A retrospective evaluation of diagnosed and treated 26 patients with CSPs in Istanbul Kanuni Sultan Suleyman Training and Research Hospital during a 6-year period was discussed. Suction curettage was performed as first-line treatment in patients with a gestation <8 weeks and myometrial thickness >2 mm. RESULTS: Twenty-two (84.6%) patients with CSPs were initially treated surgically (curettage and hysterotomy) and four (15.4%) patients were treated medically with methotrexate injections. Vacuum aspiration was performed in 19 patients as a first-line treatment, six of them needed an additional Foley balloon catheter to be inserted for tamponade because of persistent vaginal bleeding. Suction curettage was successful in 12 patients. The treatment rate for suction curettage with or without Foley balloon catheter tamponade was 16 of 19 (84.2%). CONCLUSION: The early diagnosis of a CSP (7-8 weeks gestation) with a ß-hCG level <17.000 mIU/ml and a myometrial thickness >2 mm can be treated with suction curettage with or without placement of a uterine Foley balloon as curative treatment.
