Introduction: McCune-Albright syndrome (MAS) is a rare disease caused by somatic gain-of-function variants in the gene that lead to constitutive activation of the G protein alpha subunit (Gsα). Pathologic consequences can involve several tissues. Fibrous dysplasia (FD), café-au-lait skin macules and hyperfunctioning endocrinopathies are classic manifestations.

Non-steroidal anti-inflammatory drugs (NSAIDs) and conventional analgesics are not very effective in relieving this neuropathic-like pain. Capsaicin, a compound extracted from chilli peppers, is approved for the management of localised neuropathic pain.

Advantages and disadvantages of intermittent versus daily vitamin D supplementation especially in adults with or at risk of osteoporosis are discussed by the Osteoporosis Research and Information Group (GRIO). The analysis of the literature suggests that intermittent long-term high doses vitamin D supplementation (such as 60,000IU/month or more), may increase the risk of falls, fracture and premature death in certain populations, while daily doses of 800-1000IU with calcium decrease falls and non-vertebral fractures in the elderly with vitamin D deficiency. In patients with or at risk of osteoporosis we hence recommend measuring the 25(OH)D concentration prior to supplementation and to provide vitamin D supplementation (with optimization of calcium intake if needed) to obtain a concentration between 30 and 60ng/mL.

RA was associated with an increased fracture risk in men and women, and these data will be used to update FRAX®.
Introduction: RA is a well-documented risk factor for subsequent fracture that is incorporated into the FRAX algorithm.
Background: There is considerable practice variation in labelling, diagnosis and treatment of adults with sterile bone inflammation. We developed a expert consensus recommendations on the disease definition, diagnosis and treatment of this rare condition.
Methods: Systematic literature review and Grading of Recommendations, Assessment, Development and Evaluations-based appraisal of evidence, two Delphi surveys and three digital and in-person consensus meetings with a multidisciplinary expert panel and patient representatives.
Background: A lack of medication adherence among patients with rheumatoid arthritis (RA) has been reported. Inter-professional collaborations seem essential for an optimal therapeutic management of patients. The aim of this study was to analyse the barriers and facilitators of general practitioners (GPs) for the implementation of collaborative support programmes in RA.
View Article and Find Full Text PDFOI, or bone brittle disease, is characterized by increased mineralization of bone matrix independently of clinical severity. So, a beneficial effect of antiresorptive treatments such as bisphosphonates (BP) is questionable. We aim to compare the bone matrix characteristics before and after BP pamidronate (PAM).

The objective of this study was to describe the clinical, functional, and imaging characteristics of interstitial lung disease in patients with anti-Ku antibodies. : This single-center, retrospective observational study was conducted at a tertiary referral institution.

We have evaluated quality of life (QoL) in French Fibrous Dysplasia/MacCune-Albright Syndrome (FD/MAS) patients using a qualitative approach with focus groups to explore perceptions, symptoms and limitations associated with FD/MAS and a quantitative method with the Short Form-36 (SF36) to quantify QoL. Focus groups revealed the heterogeneity of FD forms and allowed for understanding the reasons of reduced QoL.

In this study, we assess the link of the lumbar spine and hip BSI with fracture risk in older men.
Design: Prospective cohort study.

Purpose Of Review: We review the literature about patients 50 years and older with a recent clinical fracture for the presence of skeletal and extra-skeletal risks, their perspectives of imminent subsequent fracture, falls, mortality, and other risks, and on the role of the fracture liaison service (FLS) for timely secondary fracture prevention.
Recent Findings: Patients with a recent clinical fracture present with heterogeneous patterns of bone-, fall-, and comorbidity-related risks. Short-term perspectives include bone loss, increased risk of fractures, falls, and mortality, and a decrease in physical performance and quality of life.

Background: Haemophilic arthropathy (HArt) is a serious complication in patients with hemophilia. Early diagnosis and treatment are essential to minimise the development of HArt. The use of biomarkers may improve early diagnosis of HArt.

However, the Vaccine Coverage Rate of influenza remains low and multifaceted efforts are required to improve it. The aim of this study was to assess the impact on influenza vaccine perception using a digital tool among outpatients and health care workers (HCWs).
View Article and Find Full Text PDFRomosozumab, a humanized monoclonal antibody that binds and inhibits sclerostin, produces a marked increase in bone formation with a concomitant decreased bone resorption. This transient rise in bone formation in the first 2 months of treatment is mainly due to an increased modeling-based bone formation. This requires the recruitment and differentiation of osteoblasts, one possibility being a preferential switch in commitment of precursors to osteoblasts over adipocytes.

Methods: In the screening phase, 768 well-characterized micro-RNAs using Taqman low-density array cards were measured in 30 sera from 10 patients with erosive HOA, 10 patients with non-erosive HOA, and 10 controls without HOA, matched for age and body mass index (BMI). In a second step, we validated the micro-RNAs identified at the screening phase (adjusted p value < 0.
Background: knowledge on the natural history of rare diseases is necessary to improve outcomes. Disease registries may play a key role in covering these unmet needs in the rare bone and mineral community.
Objective: to map existing bone and mineral conditions registries in Europe and their characteristics.
Romosozumab treatment results in a transient early increase in bone formation and sustained decrease in bone resorption. Histomorphometric analyses revealed that the primary bone-forming effect of romosozumab is a transient early stimulation of modeling-based bone formation on cancellous and endocortical surfaces. Furthermore, preclinical studies have demonstrated that romosozumab may affect changes in the remodeling unit, resulting in positive bone balance.

We assessed the link between the baseline levels of bone turnover markers (BTMs) and the prospectively assessed bone microarchitecture decline in men. In 825 men aged 60-87 yr, we measured the serum osteocalcin (OC), bone alkaline phosphatase (BAP), N-terminal propeptide of type I procollagen (PINP), and C-terminal telopeptide of type I collagen (CTX-I), and urinary total deoxypyridinoline (tDPD).
