X-linked hypophosphataemia (XLH) is a rare metabolic bone disorder caused by pathogenic variants in the PHEX gene, which is predominantly expressed in osteoblasts, osteocytes and odontoblasts. XLH is characterized by increased synthesis of the bone-derived phosphaturic hormone fibroblast growth factor 23 (FGF23), which results in renal phosphate wasting with consecutive hypophosphataemia, rickets, osteomalacia, disproportionate short stature, oral manifestations, pseudofractures, craniosynostosis, enthesopathies and osteoarthritis. Patients with XLH should be provided with multidisciplinary care organized by a metabolic bone expert.

Background: The landscape of co-occurring birth defects among infants with congenital diaphragmatic hernia (CDH) remains underexplored.
Aims: This study aims to elucidate the complex patterns of co-occurring defects in Chinese population.
Materials And Methods: We analyzed cases from the Chinese Birth Defects Monitoring Network (2007-2019) with CDH that presented along with at least one additional defect but without a syndromic diagnosis.

Pregnant women with congenital heart disease carry a high risk of complications, especially when cardiac function is suboptimal. Increasing evidence suggests that impaired right ventricular (RV) function has a negative effect on placental function, possibly through venous congestion. We report a case series of hepatic and renal venous flow patterns in pregnant women with right ventricular dysfunction after repaired Tetralogy of Fallot (ToF), relative to those observed in normal pregnancy and preeclampsia.

The authors aimed to characterize the incidence of syrinxes and the pattern of congenital anomalies in pediatric patients with VACTERL association, with a specific focus on the presence of idiopathic syrinxes in this population.
Methods: An institutional database was retrospectively queried for all pediatric patients with VACTERL association.

Retroperitoneal teratomas are rare neoplasms in neonates, presenting with nonspecific symptoms and variable clinical features, making diagnosis challenging. Radiological investigations, particularly fetal ultrasound and contrast-enhanced computed tomography, play a critical role in their detection. Differential diagnoses include neuroblastoma, adrenal hemorrhage, and congenital cystic lesions, which share overlapping clinical and imaging features.
