An unexpected cause of severe and refractory PTH-independent hypercalcemia: case report and literature review

Archives of Endocrinology and Metabolism
Hypercalcemia is a common condition in the internal medicine practice. Sometimes its cause is not readily apparent, so extensive investigation is appropriate. Here we report an unexpected cause for hypercalcemia in an elderly woman.

Percutaneous Deployment of the Sinus‐SuperFlex‐DS Stent for Hybrid Stage I Palliation in Neonates Weighing ≤ 2.5 kg: A Multicenter Study

Catheterization and Cardiovascular Interventions, Volume 108, Issue 2, Page 644-652, August 1, 2026.
ABSTRACT Background Hybrid stage I palliation (HS1P) has developed as an alternative to the Norwood stage I palliation for neonates with hypoplastic left heart and related left‐sided obstructive lesions. HS1P is currently used in various clinical settings, such as single ventricle palliation, bridge to decision, bridge to biventricular repair, or ...
