Primary Hyperparathyroidism, Bone Disease
Bone Architectural Parameters in Postmenopausal Women Affected With Primary Hyperparathyroidism
Bone lesions are frequent in primary hyperparathyroidism (PHPT). Conventional measurement by Dual-Energy X-ray Absorptiometry does not provide enough information about the bone impact of excessive parathyroid hormone (PTH)…

Cystic Fibrosis
Bone Microarchitecture in Young Cystic Fibrosis Patients
Patients with cystic fibrosis are at risk of developing low bone mineral density (BMD) potentially leading to pathological fractures at adult age.
