Skeletal dysplasias (SDs) are a heterogeneous group of heritable disorders that affect development of bone and cartilage. Because each SD is individually rare and because of the heterogeneity within and among disorders, prenatal diagnosis of a specific SD remains challenging. Molecular genetic diagnosis involves invasive testing, which some patients are not amenable to. Further, genetic analysis is time consuming, and results may not become available in time to make pregnancy management decisions. Low-dose fetal CT can aid in the prenatal evaluation of SDs...

Introduction Higher-order fetal gestation is associated with adverse pregnancy outcomes, and monochorionic (MC) pregnancies have unique complications. Multifetal pregnancy reduction (MPR) by radiofrequency ablation may be used to optimize the outcomes of a single fetus. The purpose of this study was to determine whether pregnancy outcomes differ for elective reduction compared to reduction for medically-complicated MC multifetal pregnancies. Methods This was a retrospective cohort of patients with MC twins and higher-order multiples who underwent MPR via radiofrequency ablation at a single institution between 2008-2021...

Early identification of fetal sex is possible due to both improved ultrasound resolution and the incorporation of cell-free DNA (cfDNA) testing into routine prenatal screening services. Whilst ultrasound assessment of the external genitalia generally suffices, there are instances where identification of the internal genitalia becomes vital to allow accurate prenatal diagnosis and comprehensive counseling. This manuscript outlines the methodology and clinical utility of assessing fetal genitalia beyond conventional sonography, from the second trimester onwards and is the first to describe direct visualization of the fetal vagina...

INTRODUCTION: Primary microcephaly (MCPH) is not an uncommon disorder with multiple etiologies. There is a growing number of MCPH-related genes discovered due to the extensive application of whole-exome sequencing (WES) in clinical and research settings. Biallelic mutations in the SASS6 gene cause an extremely rare MCPH, type 14. To date, only two families with SASS6 gene-related microcephaly have been reported. CASE DESCRIPTION: We report a case of recurrent congenital microcephaly in a Chinese family...

INTRODUCTION: Autosomal recessive renal tubular dysgenesis (ARRTD) is a rare disorder of renal tubular development. ARRTD is a severe condition with high risk of fetal demise and early neonatal death with only limited case reports of survival over two years [1]. Prenatal diagnosis of ARRTD is challenging and diagnosis has only previously been confirmed after postnatal or post-mortem investigation. CASE: To the best of our knowledge, we describe the first reported case of utilising targeted genetic testing on the chorionic villous sample (CVS) to identify a homozygous variant in the angiotensinogen (AGT) gene...

INTRODUCTION: The benefits of fetal surgery are impaired by the high incidence of iatrogenic preterm prelabor rupture of the fetal membranes (iPPROM), for which chorioamniotic separation has been suggested as a potential initiator. Despite the urgent need to prevent iPPROM by sealing the fetoscopic puncture site after intervention, no approach has been clinically translated. METHODS: A mussel-inspired biomimetic glue was tested in an ovine fetal membrane (FM) defect model...

Most cases of bronchopulmonary sequestration ( BPS) regress. Prenatal intervention is needed in cases of fetal hydrothorax or hydrops. Laser is commonly used to ablate the feeding artery Case presentation: Radiofrequency ablation ( RFA) was used to ablate the feeding artery from descending aorta in a case of extralobar BPS at 29 weeks gestation. The fetus had significant pleural effusion causing mediastinal shift and collapse of lung. The effusion and tumor started decreasing from day 3 after procedure. By the time patient delivered at 36 weeks gestation, the lesion had almost resolved Conclusion : with proper technique , RFA can be safely used to ablate feeding artery in BPS...
