Introduction: Fibrous dysplasia (FD)/McCune Albright Syndrome (MAS) is a rare disorder affecting bone and hormonal glands. In FDMAS patients, autonomous GH hypersecretion (GH+) is the most common endocrinopathy after Precocious Puberty and has a great impact on the morbidity and complication rate in patients with craniofacial fibrous dysplasia. However clinical and biochemical features of GH over secretion can be subtle and awareness is warranted. We aimed to explore the GH/IG...

Autosomal dominant hypocalcemia type 1 (ADH1), caused by gain-of-function variants in the calcium-sensing receptor (CaSR, gene: CASR) and is characterized by hypocalcemia, hyperphosphatemia, low parathyroid hormone (PTH), and hypercalciuria. Calcilytics (negative allosteric modulators of the CaSR) decrease the sensitivity of activated receptors to extracellular calcium and normalize blood and urine abnormalities in ADH1 rodent models. Encaleret is an oral calcilytic u...

Introduction: Vitamin D insufficiency (25-hydroxy vitamin D <50 nmol/l) is a global health problem. Vitamin D food fortification might be the solution, but knowledge is sparse on whether fortification of various food items affects the bioavailability differently. It is generally assumed that ingesting vitamin D with a fatty meal improves the bioavailability of vitamin D. Furthermore, complex formation with whey protein isolate (WPI) may enhance the stability of vitamin D a...

Background: Focused parathyroidectomy has become the standard procedure for patients with sporadic primary hyperparathyroidism (pHPT) fulfilling the criteria for surgical therapy and requires preoperative localization procedures. Ultrasound imaging (US) and 99mTc-sestamibi-scintigraphy with/without SPECT/CT (SC) are established first line procedures. 18F-choline PET/CT (PET) has emerged as a novel sensitive and specific method. However, current reimbursem...

Background: Bone marrow fat is a unique fat depot that is regulated independently of other fat depots. Estradiol is an important regulator of bone marrow fat. This is illustrated by an increase in marrow fat fraction after menopause and a decrease following estradiol replacement. We hypothesize that estradiol is the major sex steroid that regulates bone marrow fat not only in women, but also in men.Methods: This is an open-label partly randomized interve...

Background: Patients with hypoparathyroidism experience significant physical and cognitive symptoms and reduced health-related quality of life (HRQoL). Conventional therapy for hypoparathyroidism does not fully alleviate diminished HRQoL. The Hypoparathyroidism Patient Experience Scales (HPES) were developed to assess disease-specific physical and cognitive symptoms as well as the impact of hypoparathyroidsm on HRQol. TransCon PTH, an investigational long-acting prodrug of par...

Background: Bioresorbable screws for surgical fracture treatment are of great interest for the orthopaedic community. Such implants are designed to provide stability and compression of the fracture and should dissolve after healing, thereby making removal of surgical material obsolete. Magnesium implants are a new material option. So far, long-term follow-up of fracture healing and material decay has not been studied in human. Here, we present the results of the 2.5 year follo...
