Background
Frontonasal dysplasia (FND) is a rare congenital anomaly resulting from the underdevelopment of the frontonasal process, and it can be syndromic or nonsyndromic. The typical features of FND include a deformed nose and ocular hypertelorism, which are sometimes associated with cleft lip and/or palate. Only approximately 10 cases of prenata...

Background
Congenital intracranial tumors as a group are quite rare, representing only 0.5% to 1.5% of all pediatric brain neoplasms.

Introduction
Urorectal septum malformation sequence (URSMS) is a rare congenital abnormal syndrome that is caused by the incomplete division of the cloaca. Based on whether the cloaca membrane breaks down or not, the URSMS are classified as full and partial forms. The prenatal diagnosis of URSMS remains challenging because of poor recognition to th...
The aims of this study were to evaluate the contribution of chromosomal microarray analysis (CMA) in the prenatal diagnosis of fetuses with central nervous system (CNS) anomalies but normal chromosomal karyotype. A total of 46 fetuses with CNS anomalies with or without other ultrasound anomalies but normal karyotypes were evaluated by array-based c...
The aims of our study were to evaluate the usefulness of array-based comparative genomic hybridization (aCGH) for prenatal genetic diagnosis of congenital heart disease (CHD), with and without associated anomalies, and to explore the relationship between submicroscopic chromosomal aberrations and CHD.
Seventy-six consecutive singleton fetuses with...

... For normal first trimester ultrasound screening, the four fetal brain planes that make up the standardized anatomical procedure were advised. [20] In the comparative analysis between NSG and MRI, concordance and correctness were achieved in 86.5% of cases. MRI, requested for confirmation or additional anomalies, provided clinically relevant information in 7.9% of cases. ...

... At the same time, there is growing evidence that nonoptimal temperatures increase the risk of cardiovascular and perinatal diseases 6,27 . For example, recent studies on hypertensive disorders in pregnancy have shown that heat exposure at 1-20 weeks of gestation increases the odds of preeclampsia and gestational hypertension [28][29][30] . Moreover, the change in BP for pregnant women is a U shape; it falls first and then rises, and the 20th week of gestation is an inflection point 31 . ...

... One of the large-sample studies reporting the normal ranges of fetal mMPI is based on cross-sectional data from 730 women conducted in Spain [12]. Another study was conducted in China, involving 2,081 women with singleton pregnancies [13]. ...
... Termed the "brain sparing effect," this in-utero modulation of brain vascular resistance ensures cerebral perfusion is maintained [8]. Fetal ventriculomegaly, the most commonly identified abnormality of the fetal CNS, has been associated with elevated levels of mMPI [9]. ...
... On sagittal section of the fetal cerebellar vermis, it has a shape of orange petals. The integrity of the cerebellar vermis can be judged by morphologic observation (orange petals, primary fissure, and secondary fissure) [8]. In recent years, three-dimensional ultrasound has provided a new method for observing sagittal sections of the fetal cerebellar vermis, which has improved the diagnosis of posterior fossa malformation to an accuracy of 90% [9]. ...
... When fetal cardiac parameters measured at 7 a.m. and 7 p.m. were compared, there were no significant differences. Studies on MPI, previously used to assess fetal cardiac function, have been shown that Oral Glucose Tolerance testing does not affect MPI (34), but some conditions such as fetal growth restriction (35), oligohydramnios (36) and maternal diabetes (tip 1, tip 2 and unregulated GDM) (37) increase MPI. ...

... A 6 cm long linear array is lined on the side of the transducer, so the acoustic beam is perpendicular to pelvic organs, which could significantly improve the detection rate and resolution of imaging. This transducer had been proved to be useful in visualizing fine structures of anterior department when used in transvaginal way [7,8]. Until recently, it has not been used in transrectal way to evaluate POP, especially middle compartment prolapse. ...
... deletion syndrome. Deletions within 16p13.3-13.2 or RBFOX1 were reported in three boys with different presentations of syndromic UDT (Ramanathan et al., 2010;Milone et al., 2016;Pei et al., 2016), in one case associated with an anogenital anomaly, and in a case of Müllerian aplasia (Sandbacka et al., 2013). Similarly, RBFOX1 duplication was reported in a female with cloaca and associated renal anomalies (Harrison et al., 2014), supporting a functional role for this gene in urogenital development. ...
... Associated congenital anomalies can be present in 14-20% of cases, including anomalies of the corpus callosum in case of a pericallosal/midline lipoma and cleft lip and palate in case of teratoma [1]. Brain tumors can be part of a tumor predisposition syndrome or genetic disarrangement and genetic testing should be considered, even more in the presence of associated anomalies [4,5,13,[18][19][20]. Different tumor types can be found before birth and exhibit a different prognosis for the fetus itself and the mother to be. ...
... In this study, 20 cases were found to have abnormalities, including trisomy 21, trisomy 18, partial trisomy 22, Klinefelter syndrome, and CNVs in 2, 1, 1, 1, and 15 cases, respectively, and 2 CNVs were reportedly associated with intellectual disability or developmental delay. Compared with conventional karyotyping, chromosomal microarray analysis (CMA) improves the prenatal detection rates and can identify additional, clinically significant cytogenetic information in fetuses with CNS anomalies and a normal karyotype [29]. Therefore, it is recommended that CMA be used for prenatal diagnosis and karyotype analysis of mild VM fetuses. ...
