RESUMO

PURPOSE: Cirrhosis is a diffuse pathology characterized by fibrosis of the liver and is the last stage of chronic liver diseases. It is a serious medical condition which seriously impacts reproduction and reproductive life span. The aim of this study is to evaluate the outcomes of pregnancies complicated with liver cirrhosis. METHODS: Retrospective chart review of the fetal and maternal results of 20 pregnant women with liver cirrhosis who had undergone antenatal follow-up and delivery at a tertiary center in a 12-year period was performed. RESULTS: Chronic hepatitis B was found to be the leading cause of liver cirrhosis in the study group, with a rate of 25% (n: 5/20). The average MELD score was calculated as 8.8 ± 3.5. Only three patients developed hepatic decompensation during pregnancy. Fetal demise was observed in 10% of the cases (n: 2/20, MELD scores 8 and 17). MELD score was significantly higher in the patients with adverse perinatal outcomes. CONCLUSION: Even though pregnancy is rarely observed in women with liver cirrhosis, many patients are able to achieve favorable maternal and fetal results without developing hepatic decompensation with appropriate management and close follow-up. The Model for End-Stage Liver Disease (MELD) score is a clinical tool utilized to estimate the severity and survival for chronic liver disease and was previously found to be associated with unfavorable outcomes in pregnant patients. Our study confirms this finding with the current experience from a tertiary care center.

RESUMO

Objective: To investigate the maternal, neonatal outcomes of the patients with short interdelivery interval (IDI) considering initial pregnancy outcomes. Materials and Methods: Women with two consecutive deliveries between 2016 and 2020 were included in the study. The maternal and neonatal outcomes of both pregnancies were reviewed. The time interval between consecutive deliveries was calculated. The patients were divided into two groups in terms of IDI either less or more than 24 months. Results: The number of patients with short IDI (≤24 months), and normal IDI was 1.915 and 1.370, respectively. About 15% of the women in both groups had at least one obstetric morbidity. The rates of uterine rupture, placenta previa, and peripartum hysterectomy were higher in women with short IDI. The number of patients with low birth weight, very low birth weight, and stillbirth was higher in the short IDI group. Conclusion: Patients with short interpregnancy intervals should be considered high-risk pregnancy. Adequate contraceptive methods should be used to prevent unintended pregnancies.

RESUMO

Objective: Fetal arrhythmias complicate 1-2% of all pregnancies. Ultrasound evaluation and Doppler technology are indispensable in both diagnosis and management. Digoxin, sotalol, flecainide and amiodarone are widely accepted antiarrhythmic agents that are frequently. We reviewed the maternal and fetal outcomes in cases with fetal arrhythmia in a tertiary care center in the last decade. Materials and Methods: Fetal arrhythmias were classified under three main groups: Irregular rhythms, tachyarrhythmia and bradyarrhythmia. Detailed anatomical evaluation and fetal echocardiography were performed in all cases to determine whether a structural cardiac and extracardiac anomaly accompanied fetal arrhythmia and the type of fetal arrhythmia. Digoxin was started primarily as first-line therapy in patients with persistent fetal tachyarrhythmia. In cases, not responding to digoxin, other antiarrhythmic agents (sotalol, flecainide) were combined with treatment without discontinuing digoxin. Results: Fetal arrhythmia was detected in 36 cases during the study period. 50% (n=18/36) of the cases had supraventricular tachycardia, whereas 28% (n=10/36) of them were fetal bradyarrhythmia and 22% (n=8/36) of them were with various irregular rhythms. Transplacental therapy was initiated in 13 patients with persistent supraventricular tachycardia and atrial flutter regardless of the presence of hydrops. The success rate in transplacental therapy was 77% (n=10/13). Conclusion: Successful transplacental therapy was achieved in approximately 80% of cases and delivery could be postponed to advanced gestational weeks, confirming the crucial role of this treatment for the management of tachyarrhythmia.

RESUMO

Abstract Objective To evaluate clinical characteristics, maternal and fetal outcomes in pregnant women who underwent surgery for adnexal torsion (AT). Methods All patients, who underwent surgical operation due to AT during pregnancy at the Department of Obstetrics and Gynecology, School of Medicine, Ege University between 2005 and 2020 were retrospectively investigated. Main clinical and perioperative outcomes were evaluated. Results A total of 21 patients who underwent surgery due to AT during pregnancy were included. Of all patients, 61.9% underwent laparoscopy and the remaining 38.1% underwent laparotomy. The most common surgical procedure was adnexal detorsion in both groups (48%). Mean gestational age at the time of diagnosis, duration of surgery and hospitalization were significantly lower in the laparoscopy group, when compared with the laparotomy group (p=0.006, p=0.001, and p=0.001, respectively.) One of the patients had an infection during the postoperative period. Spontaneous abortion was only observed in one case. Conclusion It can be concluded that the surgical intervention implemented for the exact diagnosis and treatment of AT (laparotomy or laparoscopy) did not have an unfavorable effect on pregnancy outcomes such as abortion, preterm delivery, and fetal anomaly. However, laparoscopy may be superior to laparotomy in terms of advantages.

RESUMO

OBJECTIVE: Tetrasomy 9p is a rare fetal condition. Cases are usually mosaic. Here, we present a non-mosaic tetrasomy 9p case with cytogenetic analysis, fluorescence in situ hybridization, microarray data, ultrasound findings, and phenotypic presentation. CASE REPORT: A pregnancy was referred to cytogenetic analysis because of increased nuchal translucency in prenatal ultrasound at 13 weeks of gestation. Prenatal laboratory analysis revealed an extra marker chromosome with a non-mosaic pattern. Ultrasonographic findings were unilateral cleft lip and palate, micrognathia, and atrioventricular septal defect at the 17th week; additionally, ventriculomegaly, left axis deviation of the fetal heart, and a single umbilical artery were determined at the 23rd week. CONCLUSION: Phenotypic severity in non-mosaic tetrasomy 9p widely differs depending on the chromosomal content. We recommend performing appropriate genetic tests in those pregnancies with the suspicion of tetrasomy 9p, evaluating the mosaic state, and following those cases with detailed ultrasonographic examinations.

RESUMO

OBJECTIVE: The purpose of this study was to analyze the clinical and perinatal outcomes along with ultrasonographic characteristics of fetuses with a cardiac tumor. METHODS: The data were obtained retrospectively between January 2010 and December 2019 in a tertiary referral center. The Cardiovascular Profile Score (CVPS) was used for the diagnosis of heart failure. Clinical outcomes of the cases identified in the postnatal period were analyzed. RESULTS: Fourteen cases were evaluated with the fetal cardiac tumor. One case made the decision to terminate the pregnancy. Perinatal death was seen in 4 (30.7 %) cases out of 13 cases. In 3/14 (21.4%) cases, a solitary cardiac tumor was found while multiple cardiac tumors were found in 11/14 (78.6%) cases. All living cases 9/9 (100%) had the diagnosis of tuberous sclerosis complex (TSC). When the cases which survived were compared with the cases which died during the prenatal period, a significant difference in tumors' biggest diameters (16.44 ± 5.12 mm vs. 32.25 ± 9.28 mm; p: .011, respectively) was found. No statistically significant difference was found in the number of the tumor(s) and heart failure. CONCLUSION: Fetal cardiac tumors can have serious perinatal mortality. The cardiac tumor size was found to be associated with perinatal mortality. The survival is not different between the cases with solitary and multiple tumors and those with and without congestive heart failure.

RESUMO

OBJECTIVE: Pulmonary hypertension (PH) is a rare maternal cardiac disorder associated with high maternal and fetal mortality. The objective of our study was to evaluate the maternal and fetal outcomes in pregnant women with PH in a single health center. STUDY DESIGN: 45 pregnant patients with PH, who had undergone antenatal follow-up and delivery at the department of gynecology and obstetrics at a referral center were retrospectively investigated. Maternal and perinatal outcomes were evaluated and descriptive statistics were reported. RESULTS: According to the WHO classification; 35 patients (78%) were in Group 1; 9 patients (20%) in Group 2 and one patient (2%) were in Group 3. Thirty-three of the cases (73%) had mild, 8 (18%) moderate and 4 (9%) severe PH. The mean delivery week was 35.5. Twenty-four of the cases (56%) delivered before the 37th week and the remaining 19 cases (44%) in the 37th week or later. Rate of cesarean section delivery was 88%. Only one case of maternal death was reported, who was initially diagnosed with PAH during pregnancy. This patient had severe PH and was in Group 1 according to the WHO classification. CONCLUSION: While the mortality rates related to PH were reported to be between 30% and 56% several decades ago, recent studies have reported the mortality rates between 5% and 25%. It is believed that the decline in the maternal mortality depended on the developments in the treatment alternatives and multidisciplinary management. However, PH is still a serious condition which requires a multidisciplinary approach and a well-planned obstetric management.

RESUMO

Systemic lupus erythematosus (SLE) is associated with a higher risk of complications in pregnancy. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been evaluated in numerous inflammatory diseases. We evaluated the possible role of these markers in SLE pregnancies. Forty-six pregnant patients with an already established diagnosis of SLE were included in the study. Complete blood counts were obtained upon admission for delivery. Seven patients were diagnosed with a flare and managed with multiple medications, whereas rest of the patients were not on any treatment or managed with monotherapy. NLR and PLR values were also evaluated between two groups and no statistically significant difference was found (p=.44 and p=.80, respectively). This study is the first to evaluate the possible role of NLR and PLR in pregnant SLE patients in the literature. Further studies are warranted for an elaborate evaluation of NLR and PLR in lupus pregnancies.Impact StatementWhat is already known on this subject? Pregnancy in the setting of SLE is associated with a higher risk of complications. Active disease increases the risk of adverse outcomes further.What the results of this study add? This study is the first to evaluate NLR and PLR in pregnancies complicated by SLE. No significant association between the course of the disease in pregnancy and NLR/PLR was documented.What the implications are of these findings for clinical practice and/or further research? Further studies on the markers to predict prognosis of SLE in pregnancy are required to improve the maternal and neonatal outcomes in this exclusive group of high-risk patients.

RESUMO

BACKGROUND: Placental accreta is a serious obstetrical entity and its management is challenging. The aim of this study was to evaluate and define our uterus sparing surgical technique in patients with placenta accreta spectrum. METHODS: The data of 21 patients who underwent uterine segmental resection during cesarean section with a preliminary diagnosis of placenta accreta spectrum at Ege University between January 2017 and December 2018 were evaluated retrospectively. RESULTS: Twenty-one patients were successfully treated with the segmental resection technique. In all cases, resected tissues were evaluated by histopathologically and the diagnosis of placenta accreta spectrum was confirmed. Hysterectomy was performed in two cases due to peri-partum hemorrhage that disrupted hemodynamics. None of the patients had complications such as visceral organ injury and wound infection. CONCLUSION: Our technique of uterine sparing surgery seems to be safe and effective in the management of placenta accreta spectrum without increasing complication rates.

RESUMO

PURPOSE: In this study, we aimed to compare the changes in the number, yield, and the percentage of karyotyping indications of the invasive prenatal diagnostic tests between the periods before and after cell-free fetal DNA was introduced to clinical use. METHOD: The number of invasive prenatal diagnostic procedures such as amniocentesis and chorionic villus sampling, indication percentages and karyotype results in the periods before (January 1, 2009-December 31, 2010), (n = 1412) and after (January 1, 2016-December 31, 2017), and (n = 593) the introduction of cell-free fetal DNA was retrospectively evaluated. RESULTS: When compared with the period before cell-free fetal DNA came into clinical use, the number of invasive prenatal diagnostic tests decreased by 58% while their yield was found to have increased (4.4% vs. 10.3%) in the period after cell-free DNA began to be used (p < 0.001). While there was a decrease in the indications due to advanced maternal age, an increase was found in ultrasonography indications for structural anomaly and the risk of a single-gene disorder (p < 0.001). Amniocentesis rate was found to have decreased in invasive prenatal diagnostic procedure types, while an increase was reported in CVS rates (p < 0.001). CONCLUSIONS: Invasive prenatal diagnosis gradually decreases over the years, but the yield of invasive prenatal diagnostic tests increases. In parallel with the rapid development of modern molecular technologies and cheaper and easier access to the tests, we think that the number of invasive prenatal diagnostic tests will experience a more dramatic decrease in the following years.

RESUMO

BACKGROUND: Keratitis-ichthyosis-deafness (KID) syndrome is a congenital ectodermal disorder characterized by keratitis, ichthyosis, and deafness. This syndrome affects multiple systems and can be fatal. CASE: A 34-year-old G2, P1 woman was admitted to the Ege University School of Medicine in Izmir, Turkey because of a rapid increase in abdominal circumference at 32 weeks gestation. Fetal anatomic screening revealed complete chorioamniotic separation, hypoplasia of the cerebellar vermis, and dysmorphic facial findings such as frontal bulging. After the delivery, the baby's whole body had granular thickened skin. Bilateral dry eye, corneal edema, and bilateral retinopathy of prematurity were diagnosed. CONCLUSION: This case report highlights the importance of prenatal diagnosis through ultrasonography and magnetic resonance imaging. This is the first case report that has antenatal ultrasonographic features in the literature.

RESUMO

INTRODUCTION: Twin-to-twin transfusion syndrome (TTTS) is a potentially lethal condition that affects pregnancies in which twins share a single placenta. The definitive treatment for TTTS is fetoscopic laser photocoagulation, a procedure in which placental blood vessels are selectively cauterized. Challenges in this procedure include difficulty in quickly identifying placental blood vessels due to the many artifacts in the endoscopic video that the surgeon uses for navigation. We propose using deep-learned segmentations of blood vessels to create masks that can be recombined with the original fetoscopic video frame in such a way that the location of placental blood vessels is discernable at a glance. METHODS: In a process approved by an institutional review board, intraoperative videos were acquired from ten fetoscopic laser photocoagulation surgeries performed at Yale New Haven Hospital. A total of 345 video frames were selected from these videos at regularly spaced time intervals. The video frames were segmented once by an expert human rater (a clinician) and once by a novice, but trained human rater (an undergraduate student). The segmentations were used to train a fully convolutional neural network of 25 layers. RESULTS: The neural network was able to produce segmentations with a high similarity to ground truth segmentations produced by an expert human rater (sensitivity = 92.15% ± 10.69%) and produced segmentations that were significantly more accurate than those produced by a novice human rater (sensitivity = 56.87% ± 21.64%; p < 0.01). CONCLUSION: A convolutional neural network can be trained to segment placental blood vessels with near-human accuracy and can exceed the accuracy of novice human raters. Recombining these segmentations with the original fetoscopic video frames can produced enhanced frames in which blood vessels are easily detectable. This has significant implications for aiding fetoscopic surgeons-especially trainees who are not yet at an expert level.

RESUMO

BACKGROUND: The only definitive treatment for twin-to-twin transfusion syndrome is minimally invasive fetoscopic surgery for the selective coagulation of placental blood vessels. Fetoscopic surgery is a technically challenging operation, mainly due to the poor visibility conditions in the uterine environment. We present the design of an algorithm for the computerized enhancement of fetoscopic video and show that the enhanced video increases the ability of human users to identify blood vessels within fetoscopic video rapidly and accurately. METHODS: A computer algorithm for the enhancement of fetoscopic video frames was created. First, optical fiber artifacts were removed via a modification of unsharp masking. Second, image contrast was increased via Contrast Limited Adaptive Histogram Equalization (CLAHE). Third, the effect of contrast enhancements on stationary features was removed by normalizing to a windowed mean of the video frames. Fourth, color information was reincorporated by combining the mean-normalized result with the unnormalized contrast enhanced image using the soft light blending algorithm. Medical trainees (n = 16) were recruited into a study to validate the algorithm. Subjects were shown enhanced or unenhanced fetoscopic video frames on a screen and were asked to identify whether a randomly placed marker fell on a blood vessel or on background. The accuracy of their responses was recorded. RESULTS: On the subset of images where subjects had the lowest mean accuracy in identifying the placement of the marker, subjects performed better when viewing video frames enhanced by the computer (accuracy 74.27%; SE 0.97) than when viewing unenhanced video frames (accuracy 63.78%; SE 2.79). This result was statistically significant (p < 0.01). CONCLUSION: Real-time computerized enhancement of fetoscopic video has the potential to ease the readability of video in poor lighting conditions, thus providing a benefit to the surgeon intraoperatively.

RESUMO

The aim of the study was to evaluate the fatty acid-binding protein-4 (FABP4) and irisin concentrations in women with polycystic ovary syndrome (PCOS). Forty-nine women with PCOS, diagnosed according to Rotterdam criteria and 39 healthy women matched for body mass index (BMI) and age. Serum irisin and plasma FABP4 concentrations were measured in both groups. The association of irisin and FABP4 concentrations with metabolic parameters were also tested. Women with PCOS had significantly lower mean serum irisin concentrations than control subjects (158.5 ± 123.3 versus 222.9 ± 152.2 ng/ml, p < 0.05). Concentrations of FABP4 in PCOS and control groups were not significantly different (10.5 ± 4.4 versus 10.9 ± 4.2 ng/ml, p > 0.05). FABP4 concentrations were correlated with BMI, waist-hip ratio (WHR) and HOMA-IR (r = 0.57, p = 0.001; r = 0.26, p = 0.03; r = 0.26, p = 0.03, respectively). No associations between irisin and all the others parameters except serum levels of LH were found. Serum irisin concentrations of women with PCOS were lower compared to the controls. Moreover, there were no difference in plasma FABP4 concentrations between women with PCOS and controls.

RESUMO

To evaluate placental elasticty in women with gestational diabetes mellitus (GDM) and non-diabetic controls. Thirty-three pregnant women with GDM according to the current criteria of the American Diabetes Association and 43 healthy pregnant women who were admitted to the antenatal clinic were recruited for this case-control study. Elasticity values of both the peripheral and the central parts of the placentas of the patients in both groups were determined by shear wave elastography (SWE) imaging. Mean elasticity values of both the central and the peripheral part of the placentas were significantly higher in GDM pregnancies (p < 0.001). No difference was observed in the mean elasticity values of the central and the peripheral part of the placentas in two groups (p > 0.05). SWE imaging technology might provide a quantitative assessment of the morphological pathologies of placentas in pregnant women with GDM.

RESUMO

The aim of this study was to determine whether homocysteine (hcy) concentrations in embryo culture media correlate with pregnancy outcome in assisted reproductive technology (ART) cycles. Forty patients who underwent single embryo transfer at the infertility clinic of a tertiary care center were recruited for this case-control study. Spent embryo culture media from all patients were collected after single embryo transfer on day 3 (n = 40). Hcy concentrations in embryo culture media were analyzed by enzyme cycling method. Patients were grouped according to the diagnosis of a clinical pregnancy. Sixteen patients were pregnant while 24 patients failed to achieve conception. Mean Hcy levels in the culture media were significantly different between the groups (p < 0.003), as 4.58 ± 1.31 µmol/l in the non-pregnant group and 3.37 ± 0.92 µmol/l in the pregnant group. Receiver operator curve analysis for determining the diagnostic potential of Hcy for pregnancy revealed an area under the curve of 0.792 (confidence interval: 0.65-0.94; p < 0.05). A cut-off value of 3.53 µmol/l was determined with a sensitivity of 83.3%, and a specificity of 68.8%. Lower hcy levels were associated with a better chance of pregnancy and better embryo grades. Hcy may be introduced as an individual metabolomic profiling marker for embryos.

RESUMO

OBJECTIVE: Early-onset pre-eclampsia is primarily associated with placental dysfunction, whereas late-onset pre-eclampsia is defined as a maternal constitutional disorder. As a protein cosynthesized with vasopressin, copeptin is a potential marker of metabolic syndrome and insulin resistance, which shares similar risk factors with pre-eclampsia. The aim of this study was to investigate the copeptin levels in patients with early-onset and late-onset pre-eclampsia. MATERIALS AND METHODS: A total of 80 pregnant women receiving antenatal and obstetric care were recruited. The patients were subdivided into four groups: Early-onset pre-eclampsia (n = 20), late-onset pre-eclampsia (n = 20), and two control groups of similar gestational ages for both pre-eclamptic groups (n = 20 in each group). The maternal serum copeptin levels were measured using an enzyme-linked immunosorbent assay. RESULTS: The mean copeptin levels were 0.92 ± 0.57 ng/mL and 1.65 ± 0.95 ng/mL in the early-onset and late-onset pre-eclampsia groups, respectively. These values were higher compared with the control groups (0.54 ± 0.25 ng/mL and 1.15 ± 0.94 ng/mL, respectively). However, the difference was only statistically significant in the early-onset pre-eclampsia group (p = 0.011). Copeptin levels were associated only with gestational age and systolic-diastolic blood pressure. CONCLUSION: Our results suggest that copeptin levels might be useful in the evaluation of the severity of pre-eclampsia. However, copeptin might be involved in early- rather than late-onset pre-eclampsia.

RESUMO

Adenomyosis is described as the benign invasion of endometrium into the myometrium, with endometrial glands and stroma surrounded by the hypertrophic and hyperplastic myometrium. It may affect 20% of female population and most widely seen among perimenopausal and multiparous women. Its etiopathogenesis, diagnosis, clinical findings and current various treatment options will be discussed in this article.

RESUMO

PURPOSE: To establish a reference range for the intracranial translucency (IT). METHODS: In this prospective study, we examined 596 singleton fetuses at 11-14 weeks of gestation using transabdominal ultrasonography. The distribution curves of the anterior-posterior diameter of the IT were established according to the gestational weeks, and the percentiles for 11-14 weeks of gestation were calculated. Regression analysis was performed to estimate the relationship between the anterior-posterior diameter of the IT and other fetal biometric parameters. RESULTS: The mean anterior-posterior diameter of the IT was 1.8 ± 0.4 mm. From 11 to 14 weeks of gestation, the IT diameter increased linearly with advancing gestation. The linear regression equation for the IT × crown-rump length (CRL) was IT = CRL × 0.0184 + 0.575 (R = 0.385, p < 0.001). The linear regression equation for the IT × biparietal diameter (BPD) was IT = BPD × 0.0532 + 0.632 (R = 0.346, p < 0.001). The linear regression equation for IT × gestational age (days) (GA) was ICT = GA × 0.024 - 0.339 (R = 0.25, p < 0.001). The linear regression analysis revealed significant correlations of the IT with CRL, BPD, and GA. CONCLUSION: The IT increases linearly with increasing CRL, BPD, gestational age in weeks, and gestational age in days.
