McCune-Albright-Syndrome (MAS) is a rare multisystem disorder presenting with polyostotic fibrous dysplasia accompanied by a list of extraskeletal features including café-aulait spots and various endocrine hyperfunctioning. There is no effective treatment for FD in MAS nowadays. Patients with MAS (n=60, 49 girls(G) and 11 boys (B) have been diagnosed and followed up during 20 years in the Institute of Pediatric Endocrinology. First clinical manifestations were pe...

Objectives: Asfotase alfa (AA), an enzyme replacement therapy, is the only approved medical treatment for pediatric-onset hypophosphatasia (HPP), which is caused by deficient tissue-nonspecific alkaline phosphatase activity. We detail the long-term efficacy of AA observed from the pediatric clinical trial program.Methods: Efficacy data collected to study completion were pooled from 3 open-label, multicenter investigations of children who manifested HPP s...

Objective: Existing case series examining outcomes following spine surgery for patients with skeletal dysplasias demonstrate high rates of complications. Yet, these earlier studies are from a single institution, contain surgeries performed almost 50 years ago, and only include patients with a diagnosis of achondroplasia. The objective is to determine contemporary outcomes after spinal surgery in patients with skeletal dypslasias, focusing on complications and revisions. We pre...

Objectives: Vertebral fractures are common in boys with DMD taking daily corticosteroids. Treatment is usually initiated when vertebral fractures have been identified. However, prophylactic treatment may be possible if reliable risk factors for vertebral fracture can be identified. The aim of this work was to compare the diagnostic accuracy of three different bone strength assessment techniques in a cohort of DMD boys.Methods: Thirty-three boys with DMD ...

Background and aims: Bone and joint infections like osteomyelitis and septic arthritis occur in ~3–12/100.000 children per year in high-income countries with predominance in males. The most common causative pathogen is Staphylococcus aureus, however, only in 50% pathogen detection succeeds. The aim of this study is to describe clinical characteristics of osteomyelitis and septic arthritis in children recruited within the EUCLIDS network (<a href="http://www.eucli...

Bone fractures of patients suffering from type 2 diabetes mellitus (T2DM) represent an emerging socioeconomic problem. Underling mechanisms are poorly understood and therapies are limited. Our previous studies have shown that sulfated hyaluronan (sHA3) suppresses osteoclast activity while supporting osteoblast function in vitro. Hence, we now investigated if sHA3 can improve the delayed fracture healing in rats with T2DM.Porous, cross-linked lactide-base...

Introduction: Cranialfacial fibrous dysplasia (CFD) presents with pain, facial asymmetry and/or neurological complications. It has been suggested that patients with CFD respond favourably to treatment with bisphosphonates, by a decrease in pain and arrest of progression. Therefore, we performed a retrospective study of 56 patients with CFD in our center.Methods: We assessed clinical characteristics and disease course. Furthermore, clinical and biochemica...

Objectives: This study aims to evaluate and compare the preferences of patients and health care professionals for osteoporotic drug treatment.Materials and methods: A discrete choice experiment was conducted among patients and health care professionals (general physicians, rheumatologists, and geriatricians) in Belgium. Participants were asked to choose between two hypothetical unlabelled drug treatments (and an opt-out option) that vary in several attri...

Odanacatib (ODN), a selective oral inhibitor of cathepsin K, is in development for the treatment of osteoporosis. In the primary efficacy analysis of the Phase 3, Long-Term ODN Fracture Trial (LOFT; NCT00529373), ODN significantly reduced fracture risk compared with placebo in postmenopausal women with osteoporosis. Pre-specified subgroup analyses evaluated the efficacy of ODN in patient subgroups.Women aged ≥65 years, without baseline radiographic...

Background: In patients with gout, urate deposition has been observed both adjacent to and within tendons, suggesting that monosodium urate monohydrate (MSU) crystals are likely to be in direct contact with tenocytes, the stromal cells of tendons. The aim of this study was to determine the effects of MSU crystals on tenocyte viability and function.Methods: Cultures of primary rat tenocytes were prepared from Wistar rat tails. Primary human tenocytes were...
