RESUMO

Our aim in this study was to investigate whether there is an association between large-for-gestational age (LGA) fetuses and myocardial performance index (MPI). This is a cross-sectional study conducted from July 2022 to July 2023. Prospectively gathered data from 65 LGA cases and 65 age and gestational-age (GA)-matched controls were analyzed. Presence of polyhydramnios and diabetes were recorded in the study group. Fetal left ventricular mod-MPI, peak systolic velocity (PSV) of E and A waves, umbilical and middle cerebral artery (MCA) pulsatility indexes (PI) were sonographically measured. Association between these sonographic measures and LGA fetuses were sought. The LGA group had 33 diabetic cases (22 GDM and 11 PGDM). The LGA group had greater mod-MPI (0.51 vs. 0.45, p = 0.0048). The LGA group also had prolonged isovolumetric contraction time (ICT), compared to controls (37 ms vs. 33 ms, p = 0.008). ICT was longer in LGA fetuses with non-diabetic mothers (38 ms vs. 33 ms, p = 0.009). LGA fetuses with polyhydramnios but without diabetic mothers had also longer ICT (39 ms vs. 33 ms, p = 0.002). Mod-MPI was similar in controls and LGA without diabetes/LGA with polyhydramnios but without diabetes subgroups. Our results indicate that fetal mod-MPI values are higher in LGA fetuses and ICT is prolonged among LGA fetuses irrespective of presence of maternal diabetes.

RESUMO

This study aims to define the associated anomalies with PLSVC, and to compare single PLSVC and bilateral superior vena cava in terms of accompanying anomalies and pregnancy outcomes. This was a retrospective study of the fetuses diagnosed with single and/or bilateral SVC at a tertiary fetal medicine center during 8 years. We detected 16 cases of single PLSVC and 84 cases of bilateral SVC. We found an association between the PLSVC and cardiac and extracardiac anomalies. Comparison between single PLSVC and BSVC cases revealed significant differences in the occurrence of heterotaxy and right isomerism. The study highlights the importance of prenatal diagnosis in PLSVC cases. Isolated PLSVC with situs solitus may be considered a benign finding, but larger studies are needed to understand the clinical implications of PLSVC in relation to chromosomal anomalies. Routine screening protocols should include three-vessel and trachea views to detect PLSVC.

RESUMO

OBJECTIVE: To assess the accuracy of prenatal echocardiography in defining pulmonary vasculature in pulmonary atresia with VSD (PAVSD). The second aim is to compare the perinatal and postnatal outcomes of different pulmonary blood supply types. STUDY DESIGN: The cases prenatally diagnosed with PAVSD between 2017 and 2022 in a single tertiary fetal medicine center were identified on the electronic database. Fetal echocardiography reports and images were reviewed retrospectively. Postnatal outcomes were acquired from the hospital records of relevant pediatric cardiology and cardiovascular surgery clinics. Fetal echocardiography results were compared with postnatal results. Perinatal and postnatal outcomes were compared between the different pulmonary vascular supply types. RESULTS: Among the 24 PAVSD cases, six were diagnosed with major aortopulmonary collateral arteries (MAPCA) dependent, eleven were diagnosed with ductus arteriosus (DA) dependent pulmonary supply, and seven were diagnosed with double pulmonary supply (MAPCA + DA) on prenatal echocardiography. Seventeen cases were live-born and have undergone postnatal investigations. Fetal echocardiography was 88.2% accurate about the type of pulmonary supply. The accuracy of fetal echocardiography regarding pulmonary vascular anatomy was 82.3%. Postoperative survival was 69.2%. Mortality before surgery and postoperative survival did not differ between pulmonary supply groups. Survival was impaired by the extracardiac anomalies. The need for early interventions was significantly higher in the DA group. CONCLUSION: Pulmonary vascularization in PAVSD can be defined precisely on fetal echocardiography. The source of pulmonary blood supply does not impact postnatal short-term outcomes significantly but it impacts the management. The associated anomalies highly contribute to postnatal mortality.

RESUMO

OBJECTIVES: To estimate factors affecting survival in prenatally diagnosed omphalocele, factors predicting genetic abnormalities, and association of omphalocele and specific groups of anomalies. METHODS: A retrospective observational study was performed, analyzing data of all omphalocele cases diagnosed prenatally in the perinatology clinic of a referral center. Demographic data, characteristics of the omphalocele (size, content, associated anomalies), results of genetic testing, pregnancy outcomes and postnatal outcomes were analyzed. RESULTS: Sixty-nine fetuses with omphalocele were included. The prevalence of omphalocele in livebirth was 0.007 %. Overall survival during the study period was 73.9 %. Twenty-eight (71.7 %) out of 39 cases with associated anomalies who were born live, survived, whereas survival was 85.7 % in the isolated cases. The most common anomaly associated with omphalocele were cardiac defects with 42 %; followed by placental or umbilical cord anomalies (28.9 %), skeletal defects (27.5), genitourinary anomalies (20.2 %), central nervous system (18.8 %) and facial anomalies (7.2 %), respectively. Eighty-five percent of the fetuses had at least one additional anomaly or ultrasound finding. Skeletal abnormalities and staged surgical repair of omphalocele were associated with survival. Associated skeletal anomalies and staged repair significantly increase the risk of postnatal death (OR: 4.6 95 % CI (1.1-19.5) and (OR: 10.3 95 % CI (1.6-63.9), respectively). CONCLUSIONS: Associated skeletal abnormalities and staged surgical repair are negatively associated with postnatal survival.

RESUMO

OBJECTIVES: This study aims to assess the diagnostic accuracy of targeted ultrasound examination in prenatal diagnosis of hypospadias and to evaluate the predictive values of defined ultrasonographic findings of hypospadias. METHODS: The cases diagnosed with hypospadias in our fetal medicine center were identified on an electronic database. The ultrasound reports, images and hospital records were reviewed retrospectively. The predictive value of prenatal ultrasound diagnosis and the predictive values of each sonographic finding were assessed according to the postnatal clinical examinations. RESULTS: Thirty-nine cases were diagnosed with hypospadias on ultrasound during the 6 years. Nine fetuses with missing postnatal examination records were excluded. Twentytwo of the remaining fetuses had their prenatal diagnosis of hypospadias confirmed in postnatal examinations, indicating a 73.3 % positive predictive value. Normal external genitalia was detected in postnatal examinations of three fetuses. Five fetuses were diagnosed with other external genital abnormalities, including micropenis (n=2), clitoromegaly (n=2), and buried penis with bifid scrotum (n=1) in postnatal examinations. The positive predictive value of prenatal ultrasound for any external genital abnormality was 90 %. CONCLUSIONS: Although the positive predictive value of ultrasound for genital anomalies is satisfying, it is slightly lower for the specific diagnosis of hypospadias. This reflects overlapping ultrasound findings of different external genitalia anomalies. Standardized, systematic evaluation of the internal and external genital organs, karyotyping and genetic sex determination are essential to achieve a precise prenatal diagnosis of hypospadias.

RESUMO

PURPOSE: To analyze postnatal abnormalities in idiopathic polyhydramnios and to estimate whether there was an association between the severity of polyhydramnios and postnatally diagnosed abnormalities. METHODS: This was a retrospective cohort study of all idiopathic polyhydramnios cases delivered at our center between 2017 and 2021. Cases were identified as idiopathic after excluding known fetal genetic or structural abnormalities (including soft markers for aneuploidies), Rh isoimmunization, fetal anemia, multifetal pregnancies, pregestational or gestational diabetes, and known infection with TORCH group agents. The primary outcome was the association between polyhydramnios degree and any abnormalities detected after birth. Additional outcomes were the odds of specific groups of abnormalities based on polyhydramnios degree. RESULTS: The prevalence of idiopathic polyhydramnios was 14.7%. Outcomes of 242 pregnancies with idiopathic polyhydramnios were analyzed. At least one neurodevelopmental, structural, or genetic abnormality was diagnosed in 16.1% of children born to women with idiopathic polyhydramnios. Moderate and severe polyhydramnios are significantly associated with at least one abnormality diagnosed after birth (45.9%, and 41.6%, respectively, p < 0.05). Neurodevelopmental disorders were the most frequent abnormality (5.4%), followed by genetic abnormalities (4.1%) and gastrointestinal abnormalities (2%). Odds of genetic abnormalities and neurodevelopmental disorders in moderate polyhydramnios were significantly higher compared to mild [OR 2.6; 95% CI 1.1-4.3 and aOR 2.4 (95% CI 1.1-3.6) respectively]. As expected, gastrointestinal anomalies were significantly associated with severe polyhydramnios [OR 3.2 (95% CI 1.9-5.5)]. CONCLUSION: Moderate and severe idiopathic polyhydramnios are associated with anomalies diagnosed after birth. Particularly high risks include neurodevelopmental disorders, genetic abnormalities, and gastrointestinal atresias.

RESUMO

Hydrometrocolpos is a pelvic cystic mass representing the distension of the vagina and uterus due to a lower genital tract obstruction causing accumulation of utero-cervical-vaginal secretions or urine in the vagina and endometrial cavity. Prenatal diagnosis is uncommon and differential diagnosis of the underlying etiologies is quite challenging in the prenatal period. We present three cases of female fetuses with hydrometrocolpos and discuss the prenatal differential diagnoses in the light of ultrasound findings along with postnatal diagnoses and outcomes.

RESUMO

AIM: Fetal growth restriction (FGR) has significant consequences on cardiac functions. This study aims to evaluate cardiac functional parameters in late-onset (FGR) fetuses and compare those appropriate for gestational age (AGA) fetuses. MATERIAL AND METHODS: Fifty-six singleton pregnancies were involved in this prospective case-control study. Delphi consensus was used to define late-onset FGR. We compared the E/A ratio, left myocardial performance index (MPI) and tricuspid annular plane systolic excursion (TAPSE) in late-onset FGR cases and gestational age-matched AGA fetuses. RESULTS: Twenty-eight late-onset FGR and 28 AGA fetuses were enrolled. The mean gestational age in the late-onset FGR group was 34.1 ± 2.3 weeks and 34.4 ± 2.1 in controls. The E/A ratio was 0.88 ± 0.09 in AGA fetuses, 0.79 ± 0.11 in the late-onset FGR group, and significantly lower in late-onset FGR fetuses (p: 0.012). Left MPI was 0.51 ± 0.09 in AGA and 0.62 ± 0.11 in the late-onset FGR group. Left MPI was markedly higher in late-onset FGR fetuses (p: 0.024). TAPSE was 7.4 ± 2.9 mm in controls and 5.2 ± 1.8 in the late-onset FGR group, and it was significantly shorter in the late-onset FGR fetuses (p: 0.016). CONCLUSION: Late-onset FGR is associated with cardiac remodeling and dysfunction. Fetal echocardiography may be beneficial to detect those subtle cardiac changes.

RESUMO

OBJECTIVES: Possible primary sites of pelvic serous cancers are, fallopian tubes, ovaries or peritoneum. Recent studies have revealed that a portion of these tumors originates from serous tubal intraepithelial carcinoma (STIC) at the distal end of fallopian tubes. In this study, the association of STIC with pelvic serous carcinomas and the pathologic parameters that indicate the tubes as the primary site were assessed. METHODS: In total, 495 pairs of fallopian tubes obtained via total abdominal hysterectomy and bilateral salpingo-oophorectomy between 2011 and 2013 were examined according to SEE-FIM protocol. Hematoxylin and eosin-stained slides were examined by pathologists. Suspicious areas were immunostained with p53 and Ki-67 to diagnose STIC precisely. RESULTS: Of the 495 cases, 110 cases were malignant. Among 34 cases of non-uterine serous carcinomas, 13 were diagnosed with STIC. STIC was located at the fimbrial end of the fallopian tubes in 12 cases. No STIC was identified in the gynecologic malignancies other than non-uterine serous pelvic carcinomas and benign gynecologic pathologies. Comparison of the ovarian and tubal cancer cases with and without STIC did not reveal a factor that helps to define the primary site. STIC was an important factor associated in a higher portion of the cases with bilateral ovarian cancer. CONCLUSION: The role of STIC in carcinogenesis continues to be discussed as it is unknown whether STIC is the precursor lesion or just associates with the malignancies. Discovering the accurate precursor lesions and tumor carcinogenesis is essential to prevent these malignancies and to develop early diagnostic methods.

RESUMO

Hypertensive disorders of pregnancy are significant contributors to maternal and perinatal morbidity and mortality. The definition, classification, and management of these disorders have evolved over time. Notably, the disease classification enables caretakers to manage the disease as well as safeguard maternal and fetal health. The approach and management for pregnancies with gestational and chronic hypertension or pre-eclampsia with or without severe features should be adequately elucidated to mitigate adverse perinatal outcomes. This review aimed to present the most recent definition and classification of hypertensive disorders of pregnancy to address their management, determine the optimal timing of birth, and establish short- and long-term follow-up protocols following parturition.

RESUMO

BACKGROUND: Pregnancy is a dynamic process associated with changes in vascular and rheological resistance. Maternal maladaptation to these changes is the leading cause of pregnancy complications such as preeclampsia. OBJECTIVE: This study aimed to assess the hemorheological alterations in pregnancies with a high risk for preeclampsia in the first trimester. METHODS: Ninety-two pregnant women were allocated into the high preeclampsia risk group (37 cases) and control groups (55 cases). Plasma and whole blood viscosity and red blood cell morphodynamic properties, including deformability and aggregation were assessed by Brookfield viscometer and laser-assisted optical rotational cell analyzer (LORRCA) at 11-14 gestational weeks. RESULTS: Whole blood viscosity was significantly higher in the high-risk group at all shear rates. Plasma viscosity and hematologic factors showed no differences between the groups. Hematocrit levels positively correlated with high blood viscosity only in the high-risk group. There were no significant changes in the other deformability and aggregation parameters. CONCLUSIONS: Changes in the whole blood viscosity of pregnant women with high preeclampsia risk refer to impaired microcirculation beginning from the early weeks of gestation. We suggest that the whole blood viscosity is consistent with the preeclampsia risk assessment in the first trimester, and its measurement might be promising for identifying high-preeclampsia-risk pregnancies.

RESUMO

Objective: The aim of the study was to retrospectively analyze the indications Techniques and complications of pregnancy termination performed in a tertiary center. Materials and Methods: All cases between 10 and 33 weeks of gestation between January 2021 and June 2023 were retrospectively analyzed. The patients were divided into two groups as group 1 with 11+0 to 21+6 gestational weeks and group 2 for those at 22+0 and 33+0 gestational weeks. Results: A total of 568 pregnancy terminations were included in the study. Among all terminations the most common fetal indications were central nervous system anomalies (148 cases, 26%) and trisomy 21 (53 cases, 9%) and the most common maternal/obstetrical Indication was previable premature rupture of the membranes (179 cases, 31.5%). Abnormal genetic results were found in 50 of 173 cases (28.9%) with a termination indication of Structural malformation who accepted invaziv genetic testing. The number of terminations with fetal indications performed after 22 weeks were 148 (41%) and 11 (7.4%) cases of these late terminations of pregnancy were anomalies expected to be diagnosed in the first trimester. Complication rates (12.4%) and abdominal termination rates (3.5%) were significantly higher in group 2 than in group 1 (p<0.05). Conclusion: Improvements in prenatal genetic screening and diagnostic techniques will undoubtedly decrease the gestational ages in terminations of pregnancies. However, there will always be cases that can neither be diagnosed earlier nor can be treated due to the nature of the anomaly. In the management of such cases, terminations will always occupy an important place in prenatal care.

RESUMO

BACKGROUND/AIM: Histopathological examination is crucial for the effective management of endometrial polyps. Immunohistochemical markers such as p16 and c-Kit may facilitate the differential diagnoses of benign and malignant polyps. The aim of the present study was to explore the expression levels of c-Kit (CD117) and p16 in endometrial polyps of postmenopausal women. MATERIALS AND METHODS: Twenty-five hysterectomy specimens with malignant endometrial polyps and hysterectomy or polypectomy specimens featuring 55 benign polyps were studied. The polyps were immunohistochemically stained for p16 and c-Kit, and differences in the expression levels of these proteins in the glandular and stromal components of benign polyps and the benign regions of the malignant polyps were assessed by using Fisher's exact test. RESULTS: The glandular components of malignant polyps exhibited significantly more intense p16 immunostaining than did benign polyps. Most immunoreactive cells were glandular cells exhibiting tubal metaplasia. The stromal components of either type of polyp did not differ in terms of p16 immunostaining. The extent of c-Kit immunostaining in benign and malignant polyps was similar. CONCLUSION: The extensive tubal metaplasia in and the p16 immunoreactivity of the glandular components of malignant polyps may be useful to distinguish such polyps from benign polyps.

RESUMO

BACKGROUND: Sarcoma botryoides of cervix is a rare variant of rhabdomyosarcomas (RMS) of female genital tract. It is usually diagnosed in first or second decade of life. In this case report, we aimed to present a 21 year-old nulligravid patient who was diagnosed with embryonal RMS of the cervix, to discuss the treatment options that have been stated in the literature, and to highlight the advantage of fertility sparing management in these young patients. CASE: We report a 21-year-old nulligravid woman complaining about a mass protruding from introitus, which was represented with a 8×7 cm "grape-like" cervical polyp on speculum examination. The histopathologic examination of the biopsy taken was combined with immunohistochemical staining with desmin, myogenin, S100, vimentin, and myoglobin. Colposcopy, second biopsy, and positron emission tomography were used during the follow-up. The histopathologic examination revealed embryonal RMS of cervix. She received three cycles of combination chemotherapy, doxorubicin and ifosfamide. She refused to have a surgery because of an unplanned, desired pregnancy at two months after the chemotherapy. She was lost during the follow-up. After having an uneventful pregnancy and a successful delivery, she reapplied at postpartum 6(th) month. Colposcopic evaluation revealed a local polypoid area, the histopathologic examination of biopsy suggested recurrence even though positron emission tomography scans were unremarkable. Therefore complementary treatment was planned as conization and pelvic lymphadenectomy. The histopathology revealed no residual tumor on the conization material and no involvement of pelvic lymph nodes. CONCLUSION: Fertility sparing management, including doxorubicin and ifosfamid combination in chemotherapy step, can be management option. Pregnancy and successful delivery is possible during the treatment. Colposcopy has importance for early detection of recurrences.
