Effect of Nifedipine Used in the Treatment of the Threat of Preterm Labor on Total Uterine Artery Blood Volume Flow Rate.

PURPOSE: Evaluation of the effect of maternal nifedipine treatment on total uterine artery blood volume flow rate (TVFR). METHODS: In this prospective study, 43 women who were admitted to the Perinatology Department of the University of Health Sciences Etlik Zübeyde Hanim Gynecology Training and Research Hospital, with the diagnosis of the threat of preterm labor, and 40 healthy pregnant women, who were randomly selected as the control group, were evaluated between July 1, 2018, and September 1, 2018. A transabdominal ultrasound examination of uterine arteries was performed both before and 48 hours after administration of oral nifedipine for TVFR measurement. For the final analysis, the TVFR levels of the group diagnosed with the threat of preterm labor and the control group were compared. RESULTS: There was no significant difference in either uterine artery pulsatility index or resistance index values as well as the diameters of the uterine arteries after nifedipine treatment (p>0.05 for all). Total uterine artery blood volume flow rate (TVFR) was 424.66±236.74 mL/min before and 543.39±309.68 mL/min after treatment with nifedipine and was statistically significantly higher (p < 0.05). CONCLUSIONS: Our study showed a statistically significant increase in total uterine artery blood volume flow rate 48 hours after oral nifedipine treatment.

Value of shear-wave elastography and cerebral-placental-uterine ratio in women diagnosed with preeclampsia and fetal growth restriction in prediction of adverse perinatal outcomes.

PURPOSE: The aim of this study was to measure placental stiffness with shear-wave elastography technique and to evaluate the relationship with cerebral-placental-uterine ratio (CPUR) and adverse perinatal outcomes in patient groups diagnosed with preeclampsia (PE) and fetal growth restriction (FGR) in the second and third trimesters compared to the control group. MATERIALS AND METHODS: This prospective cross-sectional study was conducted at our hospital between March 2019 and March 2020. The study groups were divided into three groups: PE, FGR, and low risk pregnancy (LRP) group. The study population had singleton pregnancies and the placental site was at the anterior wall. Both shear-wave elasticity (SWE) and shear-wave velocity (SWV) were measured in the placenta during pregnancy. CPUR was calculated for each group. RESULTS: A total of 147 patients were included in this study. The mean SWE (kilopascals) values in the PE group were significantly higher than in the FGR and controls (difference of means = 3.67, 9.45; 95% CI (1.23-6.1, 7-11.8); p < .05), respectively. The mean SWV values were significantly higher in PE and FGR groups than controls (p < .05). CPUR showed correlation with central maternal surface of placenta (p: .02, r: -0.184), central fetal surface of placenta (p < .001, r: -0.288), peripheral maternal surface of placenta (p: .002, r: -0.252), and peripheral fetal surface of placenta SWE values (p: .03, r: -0.181). NICU admission was correlated with central fetal surface of placenta SWE values (p: .002, r: 0.258). CONCLUSION: In conclusion, we demonstrated increased placental stiffness in both the PE and the FGR group. Also, this difference was found to be more prominent in preeclampsia. This technique seems useful for assessment of placental function and may strengthen the utility of Doppler parameters for predicting adverse perinatal outcomes in high-risk pregnancies.

Fetal pulmonary artery Doppler parameters in pregnancies complicated with intrahepatic cholestasis of pregnancy: a prospective case-control study

Objective: The primary aim of this study was to determine whether pulmonary artery acceleration time (AT) to ejection time (ET) ratio (PATET) was altered in fetuses of mothers with intrahepatic cholestasis of pregnancy (IHCP). The secondary aim was to investigate the association between fetal pulmonary artery Doppler parameters with neonatal outcomes in pregnancies complicated by IHCP. Material and Methods: This prospective case control study was conducted in a tertiary perinatal-neonatal center. A total of 18 fetuses whose mothers' pregnancies were complicated by IHCP were included as the study group and a total of 37 fetuses of mothers with healthy pregnancies were selected as controls. Fetal pulmonary artery Doppler parameters (AT; ET; AT/ET ratio) were assessed and neonatal outcomes were evaluated. Results: Mean pulmonary artery AT, ET and PATET were significantly different between the groups (p=0.001, p=0.024 and p=0.003, respectively). The mean PATET value in the IHCP group was 0.217±0.029 while in the control group it was 0.180±0.020. While PATET values were correlated with gestational age at birth, respiratory distress and need for neonatal intensive care admission were not correlated with PATET. Conclusion: Higher values of PATET may be a useful biomarker of fetal lung damage, secondary to IHCP.

Role of derived neutrophil-to-lymphocyte ratio, uric acid-to-creatinine ratio and Delta neutrophil index for predicting neonatal outcomes in pregnancies with preeclampsia.

We aimed to compare the maternal and neonatal systemic inflammatory markers, platelet indices and new indices in biochemical parameters in women with preeclampsia and healthy controls. The secondary aim was to investigate whether there was a relationship between maternal hematological markers and neonatal outcomes. A retrospective case control study was conducted in a tertiary hospital. Maternal demographic and birth characteristics, complete blood count indices, derived neutrophil to lymphocyte ratio (dNLR), Delta neutrophil index (DNI), uric acid-to-creatinine (Cre) ratio and uric acid-to-alanine transaminase ratio, neonatal hematological parameters were compared between the preeclamptic group and control group. The study consisted of 170 cases (84 preeclampsia and 86 control). Neutrophil-to-lymphocyte ratio (NLR), dNLR, blood urea nitrogen (BUN), creatinine (Cre), uric acid, LDH, aspartate transaminase (AST) and alanine aminotransferase (ALT), uric acid-to-Cre ratio and uric acid-to-ALT ratio were higher and statistically significant in the preeclamptic group than in control ones (p: 0.000 - BUN, Cre, uric acid, LDH, p: 0.001 - AST, p: 0.004 - ALT, p: 0.000 - uric acid-to-Cre ratio, p: 0.009 - uric acid-to-ALT ratio, respectively). NLR and platelet-to-lymphocyte (PLR) ratio were significantly higher in newborns of preeclamptic mothers (p: 0.039; p: 0.004, respectively). A low-moderate correlation between maternal uric acid-to-Cre ratio and neonatal PLR was detected (r: 0.193; p: 0.013). Moreover, moderate negative correlations between maternal PLR (r:-0.231, p: 0.002), uric acid (r: 0.332, p:0.000) and adverse neonatal outcomes were found. Uric acid and PLR, which can be easily calculated clinically may predict adverse neonatal outcomes.IMPACT STATEMENTWhat is already known about this topic? Preeclampsia is known as a significant cause of maternal morbidity and mortality. Haematological indices have been evaluated for the prognosis of many kinds of disease.What do the results of this study add? This study has focussed on new combined haematological-biochemical indices and its relationship with neonatal outcomes. Both higher NLR, derived NLR, DNI and lower PLR were recorded as useful markers for preeclampsia.What are the implications of these findings for clinical practice and/or further research? Some indices that were calculated by assessing basic and simple blood parameters may help clinicians to predict clinical outcomes of preeclampsia.

Experience of a tertiary pandemic centre on the labour and delivery of 337 pregnant women with COVID-19: a prospective cohort study from Turkey.

The aim of the present study is to share the experience of a tertiary reference pandemic centre on the labour and delivery of pregnant women with coronavirus disease 2019 (COVID-19). This prospective cohort study was conducted on pregnant women with COVID-19 (n = 337). Patients were divided into two groups based on their severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR) positivity (n = 103 positive and n = 234 negative) during the delivery. Thereafter, clinical characteristics and perinatal outcomes were compared between the groups. Moreover, delivery characteristics and clinical features were compared between primary caesarean section (n = 117) and normal spontaneous vaginal delivery cases (n = 100). Labour induction was performed in 16% of cases with a failure rate of 35%. Caesarean rate was 70% and the most common indication was worsening in maternal condition. Significant, positive and moderate correlations were observed between COVID-19 severity at admission (r = 0.422, p<.001), radiologic findings consistent with COVID-19 (r = 0.400, p<.001), the necessity for oxygen support during the delivery (r = 0.406, p<.001) and postpartum worsening in maternal condition. A significant, positive weak correlation was found between caesarean delivery and postpartum worsening in maternal condition (r = 0.176, p<.001). COVID-19 seems to be associated with increased rates of obstetric complications and caesarean delivery.Impact StatementWhat is already known on this subject? Increased rates of foetal distress and caesarean section were reported in pregnant women with COVID-19. Appropriate management of labour and delivery in infected pregnant women is crucial to obtain favourable perinatal outcomes.What do the results of this study add? COVID-19 seems to be associated with increased rates of obstetric complications and caesarean delivery. PCR positive group had significantly higher primary and prelabor caesarean delivery rates. Severe/critic COVID-19 infection rate was significantly higher in the primary caesarean group. Significant, positive and moderate correlations were observed between COVID-19 severity at admission, radiologic findings consistent with COVID-19, the necessity for oxygen support during the delivery and postpartum worsening in maternal condition. A significant, positive weak correlation was found between caesarean delivery and postpartum worsening in maternal condition.What are the implications of these findings for clinical practice and/or further research? Management and delivery of pregnant women with COVID-19 should be individualised. The findings of the present study may lead to the establishment of future obstetric protocols in this special population.

Maternal mortality due to valvular heart disease: a population-based study in Turkey.

BACKGROUND/AIM: To assess the clinical and demographic features of maternal mortality cases among patients with cardiac valvular diseases between 2012 and 2019. METHODS: Maternal mortality due to valvular heart disease between January 2012 and December 2019 in Turkey was retrospectively analyzed. The cases were classified according to New York Heart Association (NYHA) classification based on the severity of the heart disease. NYHA classification groups were divided into two; as class I-II (n = 34) and class III-IV (n = 31). Two groups were compared in terms of demographic and clinical characteristics. RESULTS: Valvular heart disease was diagnosed in 41 (63.1%) of the cases before pregnancy. It was found that 100% (n = 21) of the warfarin users had switched to low molecular weight heparin treatment due to concerns about warfarin embryopathy after the diagnosis of pregnancy, and only 14.2% (n = 3) of them had been monitorized with Antifactor Xa activity to evaluate the effectiveness of the medication. Two NYHA groups had similar clinical characteristics. Intensive care unit admission rate, frequency of prosthetic valve, rate of thromboprophylaxis, type of valvular disease and reasons of maternal death were similar between the NYHA groups (p < 0.05). CONCLUSION: Maternal mortality may be observed in cases with NYHA class I-II in almost similar rates with NYHA class III-IV. Therefore, it is crucial to adequately assess the mortality risk of pregnant women with cardiac valvular pathologies and to achieve early diagnosis and appropriate treatment in order to reduce maternal mortality.

Evaluation of Fetal Serum Thiol/Disulfide Homeostasis and Ischemia-Modified Albumin Levels in Fetal Distress.

Aim: We investigated the association of fetal serum thiol/disulfide homeostasis and ischemia-modified albumin (IMA) levels with fetal distress (FD). Methods: Umbilical cord blood for native thiol, total thiol, disulfide, albumin, and IMA analysis was obtained from 44 pregnant women over 34 weeks gestation undergoing cesarean section due to non-acute FD, and from 61 healthy pregnant women who underwent elective cesarean section Results: Native thiol and total thiol levels were significantly lower in the FD group (p = 0.02 and p = 0.014, respectively). Although disulfide/native thiol and disulfide/total thiol ratios were higher in the FD group, the difference was statistically insignificant (p = 0.805). The IMA levels were significantly higher in the FD group (p = 0.013). Conclusion: The thiol-disulfide homeostasis shifts toward the oxidant direction during the FD pathogenesis and the increased IMA levels may be the best indicator of an underlying non-acute ischemic condition.

Role of cervical length and placental alpha microglobulin-1 to predict preterm birth.

INTRODUCTION: Preterm labor is the leading cause of premature mortality and morbidity. Therefore, to rule-in and rule-out preterm delivery is a very important issue in our clinical practice. OBJECTIVE: The aim of this study was to investigate the value of placental alpha microglobulin-1 (PAMG-1) molecule positivity in cervicovaginal secretions of women who have a CL <25 mm and presenting with preterm labor symptoms to predict spontaneous preterm birth within seven days. MATERIALS AND METHODS: This was a prospective cohort study conducted in Ankara University Department of Obstetrics and Gynecology between August 2017 and February 2019 on the patients who had Preterm labor symptoms, <25 mm transvaginal cervical length (CL), clinically intact membranes. The primary outcome of the study was the power of CL and PAMG-1 positivity on the prediction of preterm birth in seven days. RESULTS: Sensitivity and specificity values of PAMG-1 in our study population to predict spontaneous preterm birth in seven days were calculated 52.94% and 98.84%, respectively, negative predictive value (NPV) and positive predictive value (PPV) were calculated 91.4% and 90%, respectively. When we investigated our data according to different CL cutoffs, sensitivity and NPV for 20 mm cutoff were 88.24% and 96.3% that was better than PAMG-1, but specificity and PPV were 60.47% and 30.61%, respectively, that was more ineffective than PAMG-1. If we calculate the values according to 15 mm and 10 mm CL cutoffs sensitivity values were 58.8% and 23.53%, specificity values were 81.4% and 91.86%, NPV were 90.9% and 85.87%, PPV were 38.46% and 36.36%, respectively. Finally, accuracy value of PAMG-1 to predict spontaneous preterm birth in seven days was 91.26% that was better than other CL cutoffs (20 mm, 15 mm, and 10 mm). CONCLUSION: PAMG-1 molecule with high NPV and PPV (91.4% and 90%) combination will contribute our clinical decision on the population who had preterm labor symptoms and a CL shorter than 25 mm.

Evaluation of the relationship between placental stiffness measured by shear wave elastography and perinatal outcomes in women with gestational diabetes mellitus.

BACKGROUND: Recently, studies on placental elastography in high-risk pregnancies continue to increase. The shear wave technique can contribute to the management of gestational diabetes mellitus (GDM) and improve perinatal outcomes by measuring placental stiffness.Purpose: To evaluate the relationship between placental stiffness measured by shear wave elastography (SWE) and perinatal outcomes in women with GDM.Material and Methods: This prospective cross-sectional study was conducted at our hospital between March and October 2020. The participants were divided into three groups: GDM-A1 group (regulated by dietary modifications); GDM-A2 group (needed pharmacologic treatment); and low-risk pregnancy (LRP) group. Both SWE and shear wave velocity (SWV) were measured in the placenta during pregnancy. RESULTS: In total, 111 women were included in the study. The mean SWE (kPa) values for the GDM-A1, GDM-A2, and LRP groups were 10.4 (range 3.1-23.3), 13 (range 4.3-29.6), and 8.3 (range 3.2-15.1), respectively. The mean HbA1c and fasting glucose values of diabetes groups showed strongly positive correlation with mean SWE and SWV values (P < 0.001, r=0.875; P < 0.001, r=0.856; P < 0.001, r=0.791; P < 0.001, r=0.740), respectively. The SWE values of central maternal and fetal surfaces of the placenta (P=0.01, r=0.242; P < 0.001, r=0.333) showed a moderately positive correlation with admission to the neonatal intensive care unit. CONCLUSION: Placental stiffness has increased in the GDM-A2 group when compared to the GDM-A1 and LRP groups. We also observed a strong positive correlation between HbA1c, fasting glucose values, and increased elasticity values in diabetic patients with metabolic dysregulation that may have clinical value.

Neurosonographic assessments of corpus callosum related structures in growth-restricted fetuses.

PURPOSE: The aim of this study was to evaluate whether corpus callosum length (CCL), corpus callosum-fastigium length (CCFL) and the angle between CCL-CCFL (CCFA) were altered in growth-restricted fetuses. METHODS: This prospective case-control study was conducted in a tertiary center. A total of 80 singleton fetuses were included in the study, classified as 36 late-onset growth-restricted fetuses and 44 adequate-for-gestational-age fetuses. All biometric measurements and Doppler assessments of umbilical artery, middle cerebral artery, and ductus venosus were performed via the trans-abdominal route. CCL, CCLF, and CCFA were assessed via the trans-vaginal route. RESULTS: Late-onset growth-restricted fetuses showed significantly reduced CCL and CCFL. There was no statistically significant differences in terms of CCFA. Moderate-high correlations between CCL and biparietal diameter, head circumference, abdominal circumference, FL and gestational age were detected (r: 0.482 p: 0.000; r: 0.537 p: 0.000; r: 0.488 p: 0.000; r: 0.519 p: 0.000; and r: 0.472 p: 0.000, respectively). CONCLUSION: This study adds to the literature that CCFA has not changed despite the decrease in CCL and CCFL in late-onset fetal growth restriction that might be a result of the redistribution of cerebral blood flow. To clarify the prognostic implications of these results in terms of neural and cognitive functions in postnatal life, there is a need for larger prospective studies.

The effect of real-time polymerase chain reaction cycle threshold values on perinatal outcomes of pregnant women with COVID-19.

OBJECTIVE: To evaluate the effect of cycle threshold (Ct) values on the pregnancy outcomes of women with coronavirus disease 2019 (COVID-19). MATERIALS AND METHODS: This prospective cohort study was conducted on pregnant women with COVID-19. A real-time polymerase chain reaction (RT-PCR) assay of a nasopharyngeal and oropharyngeal specimen was used for the diagnosis. Initial Ct values for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RT-PCR tests were recorded. 22.9 was the 50th percentile Ct value of the study population. The study population was divided into two groups based on their Ct values: (1) Cases with Higher Ct values (Ct > 22.9)(n = 50) and (2) Cases with lower Ct values (Ct ≤ 22.9)(n = 55). Demographic features, clinical characteristics, disease progression, laboratory test results and pregnancy outcomes were compared between the groups. A receiver operating characteristic (ROC) curve was used to assess the performance of Ct values in predicting obstetric complications. RESULTS: Obstetric complication rate was significantly higher in cases with lower Ct values (p < .001). A significantly lower lymphocyte count together with higher ESR, procalcitonin and IL-6 values were observed in the cases with lower Ct values (p > .05). Additionally, a significantly higher NICU admission rate and longer hospital stays were present in the cases with lower Ct values (p > .05). The value in ROC curves with the best balance of sensitivity/specificity was 22.5 (85.7% sensitivity, 63.6% specificity). CONCLUSION: Lower Ct values may be associated with an increased rate of obstetric complications in pregnant women with COVID-19. Physicians should be cautious in the management of cases with Ct levels below 22.5.

Can Derived Neutrophil-to-Lymphocyte Ratio, Platelet-to-Lymphocyte Ratio, and Delta Neutrophil Index Predict Spontaneous Abortion?

OBJECTIVE: To evaluate the efficacy of complete blood count indices for the prediction of miscarriage. MATERIALS AND METHODS: A retrospective case-control study was conducted in a tertiary hospital. This study consisted of 389 cases (32 elective and 193 spontaneous abortions, 164 healthy pregnancies). Maternal demographic characteristics, complete blood cell (CBC) parameters, neutrophil-lymphocyte ratio (NLR), derived NLR, systemic inflammatory immune index (SII), platelet-to-lymphocyte ratio (PLR), and delta neutrophil index (DNI) that were in the routine first trimester CBC were compared between groups. RESULTS: There were no significant differences among groups in terms of demographic and obstetric characteristics. Statistically significant differences were observed for Hb, white blood cell (WBC), lymphocyte (L), NLR, SII, and PLR between the subgroups (p=0.003, p=0.045, p=0.000, p=0.002, p=0.043, p=0.010, respectively). There were no significant differences among groups in terms of the remaining parameters. When healthy pregnancies and spontaneous abortions were compared, statistically significant differences were detected for NLR, SII, PLR (p=0.001, p=0.039, and p=0.000, respectively). Moreover, when healthy pregnancies and elective abortions were compared, only NLR was found as statistically different (p=0.050). Area under curve (AUC) was calculated for PLR as 0.659 (%95 CI: 0.582-0.735) and a cut-off value of 158.1 was found with highest sensitivity and specificity (60.6 % and 61.6%, respectively) according to the results obtained from Youden's index. AUC was calculated for NLR as 0.591 (%95 CI: 0.507-0.675) and a cut-off value of 3.135 was found with highest sensitivity and specificity (56% and 54.5%) according to the results obtained from Youden's index. CONCLUSION: In conclusion, decreased PLR and NLR levels may be used as practical and cost-effective markers for the prediction of miscarriages.

Investigating the risk of maternal-fetal transmission of SARS-CoV-2 in early pregnancy.

INTRODUCTION: The possibility of vertical transmission of SARS-CoV-2 from the mother to the fetus is one of the most crucial issues regarding the COVID-19 effects on pregnancy. In this study, we aimed to explore the risk of maternal-fetal transmission before 24 weeks of gestation, through analysis of abortion materials collected from PCR-positive women with pregnancy loss. To the best of our knowledge, apart from case reports, this study is the first prospective work on the vertical transmission of SARS-CoV-2 in early pregnancy. METHODS: The patients who had attended our clinic with the diagnosis of pregnancy loss before 24 weeks of gestation were screened for COVID-19. Vertical transmission in PCR-positive women was assessed through the presence of SARS-CoV-2 RNA in fetal-placental tissues by rt-PCR test. RESULTS: 24 of 210 (%11,4) pregnant women participating in the study had positive rt-PCR results. Placenta and curettage material samples of these PCR-positive patients were analyzed and all valid test results (21 samples) were negative for SARS CoV-2 RNA. In three cases, the rt-PCR results were invalid due to failed internal controls. DISCUSSION: In the literature, the possibility of intrauterine vertical transmission of SARS-CoV-2 is still controversial. The findings of the present study did not reveal any evidence of vertical transmission of SARS-CoV-2 in early pregnancy.

Skin Color May Predict Intra-Abdominal Adhesions During Repeated Caesarean Section Deliveries.

OBJECTIVE: Caesarean rates have increased rapidly for various reasons recently. One of the important reasons among these is medicolegal problems. Our aim with this study was to preoperatively predict abdominal adhesion density by combining the scar tissue morphology formed in the post-caesarean Pfannenstiel incision line and the skin color scoring of the patients. MATERIAL AND METHODS: Patients who had undergone one caesarean section previously, completed their terms (37-39 weeks) and were under 35 years old were included in the study. Skin color scoring of the patients was performed using the Fitzpatrick skin color scale. Intra-abdominal adhesion scoring of the participant patients was performed using Nair's adhesion scoring system. RESULTS: The change in abdominal adhesion scores was evaluated based on the Fitzpatrick color scale. Adhesion scores per the Nair intra-abdominal adhesion scoring system were found to be 0.04±0.209 in the FP1 group, 0.35±0.662 in the FP2 group, 1.58±0.923 in the FP3 group, and 2.33±0.577 in the FP4 group (p<0.05). These results showed a significant increase in adhesion density with increasing skin color darkness. Based on these results, it was observed that the abdominal adhesion scores and the frequency of depressed skin scar were significantly increased with increasing Fitzpatrick scores (p<0.05). CONCLUSION: The aim of this study was to increase the prediction rates by adding the skin color scoring to the scar tissue characteristics, which have been used in previous studies. The results of this study indicate that the combination of these two parameters may be more effective in predicting intra-abdominal adhesions. Nevertheless, there is a need for studies with a much higher number of patients and multiple parameters to be able to predict intra-abdominal adhesion density preoperatively with greater accuracy.

Maternal deaths with epilepsy: A population-based study in Turkey.

OBJECTIVE: To evaluate the clinical characteristics of maternal deaths with epilepsy in Turkey. STUDY DESIGN: This epidemiological population-based study was conducted on all consecutive early maternal deaths with epilepsy in Turkey from 2012 to 2019. Maternal deaths accompanied by epilepsy as a comorbidity (n = 13) were evaluated separately. Epilepsy related maternal deaths were divided into two groups: 1) status epilepticus (n = 19) and 2) Sudden unexpected death in epilepsy (n = 19). Two groups were compared in terms of demographic features and clinical characteristics. RESULTS: Maternal deaths with epilepsy ranged between 2.5 % and 5.3 % among total maternal deaths. Pulmonary embolism (32 %), cerebrovascular event (23 %), and cerebral vein thrombosis (15.4 %) were the leading mortality reasons in maternal deaths accompanied by epilepsy. Epilepsy duration, the time interval between pregnancy and the last epileptic seizure, compatibility with medication, rates of preconceptional counseling, and regular antenatal follow-up were all significantly higher in the sudden unexpected death in epilepsy group. The perinatal complication rate was significantly higher in the status epilepticus group (p > 0.05). CONCLUSION: Physicians who deal with pregnant women with epilepsy should be attentive for severe complications and the increased risk of maternal mortality in these cases should be kept in mind.

The Effect of Anesthesia Type During Delivery on Neonatal Otoacoustic Emission Hearing Test Results: A Tertiary Center Experience.

BACKGROUND: Hearing is essential for the healthy development of an infant as language is one of the main stimulants of intellectual capacity. We investigate the effect of anesthesia type during delivery on neonatal otoacoustic emission (OAE) hearing test results. METHODS: This retrospective cross-sectional study includes 1,493 healthy, full-term (39/0-40/6 gestational weeks) newborns of healthy women and who were delivered by cesarean section. Newborns were divided into 2 groups based on their anesthesia type during delivery: 1) general anesthesia group (n=160), and 2) spinal anesthesia group (n=1333). Maternal age, anesthesia type, birth weight, gestational age at birth, neonatal gender, 1st-5th minute APGAR scores, and OAE results were compared between the groups. RESULTS: 1287 (86.2%) newborns were reported to have passed the first step of OAE; 206 (13.8%) newborns were reported to have failed the first step and passed the second test. In the general anesthesia group, 133 (83.1%) of the newborns passed the first OAE test and 27 (16.9%) newborns had false-positive results. In the spinal anesthesia group, 1,154 (86.6%) of the newborns passed the first OAE test and 179 (13.4%) newborns had false-positive results. The difference between the 2 groups by false-positive values was found to be statistically significant (p<0.001). CONCLUSIONS: Type of delivery anesthesia may have an effect on the false-positive rates of OAE test results.

Impact of timing on wound dressing removal after caesarean delivery: a multicentre, randomised controlled trial.

We compared wound dressing removal at 24 hours versus 48 hours following low-risk caesarean deliveries. This multicentre, randomised, controlled study included patients 18-44 years of age with low-risk term, singleton pregnancies. The randomisation was done weekly. Scheduled caesarean deliveries without labour were included. For comparison, the Additional treatment, Serous discharge, Erythema, Purulent exudate, Separation of deep tissues, Isolation of bacteria, Stay in hospital > 14 days (ASEPSIS) score for wound healing assessment was modified. The absolute scores were obtained based on a one-day reading rather than the five-day reading used in ASEPSIS. Zero ("0") was assigned as a complete healing. Higher scores were associated with more severe disruption of healing. The patients were enrolled between March 2015 and February 2017. The demographics were not statistically different. The wound scoring was similar in the groups at discharge and first-week evaluation. At the six weeks post-surgery, the wound scoring was significantly less in the 48-hour (3.9%) versus the 24-hour group (9%; p = .002). Dressing removal at 48 hours had a lower scoring in the low-risk population with scheduled caesarean deliveries.IMPACT STATEMENTWhat is already known on this subject? Surgical dressings are used to provide suitable conditions to heal caesarean incisions. There has been a limited number of studies on the evaluation of ideal timing on wound dressing removal after a caesarean delivery. These studies concluded there are no increased wound complications with removal at six hours versus 24 hours or within or beyond 48 hours after surgery.What do the results of this study add? The postoperative removal of the wound dressing at 48 hours had a lower wound score at six weeks than the removal at 24 hours for women with uncomplicated scheduled caesarean deliveries.What are the implications of these findings for clinical practice and/or further research? Early discharge after caesarean delivery is becoming more common. Dressing removal at 24 hours versus 48 hours becomes more crucial and needs to be clarified. Besides, high-risk populations, different skin closure techniques, and patients in labour should be addressed separately.

Selection of a correct treatment protocol in caesarean scar pregnancies.

OBJECTIVE: This study aims at assessing the effectiveness of various treatment protocols with the help of some parameters in caesarean scar pregnancies. METHODS: A total of 26 patients were assessed in the study. The patients were divided into 4 groups. Group 1 consisted of those who had a wedge resection (n = 7), group 2 those who had a suction curettage (n = 10), group 3 those who had a systemic methotrexate (MTX) (n = 5) and group 4 those who had a systemic + local MTX (n = 4). The ßHcg half-lives, haemoglobin levels at the time of admittance and discharge, and hospital stays of the groups were compared. RESULTS: The difference between group 1 and group 4 was found significant (p = 0.002) with respect to days of hospital stay. There was no statistically significant difference between the groups with respect to ßHcg half-lives and haemoglobin values. CONCLUSION: The results of our study showed that there were no significant differences between treatment outcomes when appropriate protocols were employed. Therefore, the important point in CSPs is to assess correctly the type of CSP, the myometrial thickness and the patient's hemodynamic condition and select the most appropriate protocol accordingly rather than trying to establish a single standard treatment protocol.

Analysis of cystic hygroma diagnosed in the first trimester: Single-center experience

Objective: To evaluate the obstetric outcomes of fetuses with cystic hygroma other than karyotype abnormalities and structural malformations. Material and Methods: We conducted a retrospective study based on the review of medical records of pregnant women in whom ultrasonographic diagnosis of fetal cystic hygroma was established in the first trimester from January 2014 to October 2018. All patients were offered genetic counselling and prenatal invasive diagnostic procedures to obtain fetal karyotype. For ongoing pregnancies fetal echocardiography and detailed second trimester sonographic anomaly screening was performed by a perinatologist/pediatric cardiologist. The demographic characteristics of the women and the results of the karyotype analysis were obtained from the database of our hospital and correlated with the obstetric outcomes. Results: Within a five-year period, there were 106 cases of fetal cystic hygroma. Of those, fetal cardiac malformations were detected in four and micrognathia in one fetus. Eighty-five women underwent fetal invasive procedures and karyotype abnormalities were detected in 52 of the cases. Fetal outcomes of 33 cases with normal karyotype and 21 cases in whom karyotyping analysis were not performed due to patient refusal were enrolled into the study. Obstetric outcomes of 21 women who refused karyotyping consisted of 13 livebirths, seven missed abortions, and one fetal death, whereas those of 33 women with normal karyotype were; 12 livebirths, 12 missed abortions, two hydrops fetalis, and five fetal deaths. Nineteen of 33 fetuses with a normal karyotype and eight of 21 fetuses in whom karyotyping was not performed were terminated. Conclusion: The presence of cystic hygroma carries a high risk for fetal karyotype abnormalities and cardiac malformations. The postnatal outcomes of the fetuses with cystic hygroma appeared to be correlated with the absence of structural malformations and karyotype abnormalities.

Fetal fibular hemimelia with focal femoral deficiency: A case report.

Fibular hemimelia (FH) is a congenital deficiency in which a part or all of the fibular bone is hypoplastic or aplastic and associated with hypoplastic tibia and foot anomalies. The main differential diagnoses include proximal focal femoral dysplasia, Femur-Fibula-Ulna syndrome, and Femoral Hypoplasia-Unusual Facies syndrome. Proximal focal femoral dysplasia, which has a short, angulated femur with normal mineralization may be associated with FH. We report a case of unilateral FH with focal femoral deficiency detected at 18 weeks of gestation during a routine ultrasonographic anatomic screening. Sonographic findings were a unilateral short femur (1.8 cm, 3 weeks shorter than expected for gestational weeks), agenesis of ipsilateral fibula and angulation of ipsilateral tibial shaft. During a routine ultrasonographic anatomic scan, all the long bones are carefully measured and evaluated. Long bone shortness can be a part of syndrome or an isolated finding.
