Goal: The use of intramedullary telescopic constructs for osteosynthesis in surgical correction of bone deformities in children with systemic skeletal disease can be complicated by delayed bony union, and the structural and functional pathology of bone in patients with these disorders do not always make it possible to avoid displacement of bone fragments and effectively correct the deformity.Methods: Analysis of treatment of 11 patients of femoral and ti...

Introduction: Vitamin D is known to be important for bone health. Still, the significance of serum 25-hydroxy vitamin D concentrations (s-25OHD) for hip fracture risk of the elderly is uncertain. Discordant findings may in part be explained by difficulties of RCTs or large cohort studies to reach both the frail and the healthy elderly. The objectives of this study were to determine the risk of hip fractures of the elderly related to s-25OHD, including both the frail and the he...

Introduction: The RANKL/RANK/OPG system has a key role in bone metabolism. Beyond its role in bone loss, its importance was also documented during inflammation which occurrs in inflammatory bowel disease (IBD). The aim of this study was to investigate the expression of the receptor activator of NF-κB ligand (RANKL) and its receptors RANK as well as its decoy receptor osteoprotegerin (OPG) in the colon during experimantal IBD and following BMP7 or corticosteroid therapy.</...

Hypoparathyroidism results in low bone turnover and increased bone mineral density (BMD). Replacing deficient PTH with rhPTH(1–84) has the potential to correct these skeletal abnormalities. To investigate the effect of rhPTH(1–84) on BMD and bone turnover markers (BTMs), data from two studies were assessed.REPLACE, a double-blind, multicenter, placebo-controlled study, randomized 134 patients with hypoparathyroidism to receive once-daily rhPTH(...

Introduction: The effectiveness of intravenous pamidronate was assessed independently and in combination with corrective osteotomy surgery for lower extremity deformities in children with osteogenesis imperfecta.Methods: Orthopaedic treatment was conducted in 21 patients with OI (type I–ten patients, type III–11 patients), including 13 males and eight females with mean age 9.4±0.6. All patients received calcium supplements and active forms...

Introduction: System epidermal nevus with hyperkeratosis (SENHK) – congenital epidermal formation characterized by hyperkeratosis, papillomatosis and acanthosis with elongation of intrapapillary epithelial strands. The main manifestations of metabolic bone disorders are system osteoporosis (SO) and violation of vitamin D metabolism. The urgency message is caused by a combination of the two above mentioned diseases in one patient.Methods: We present ...

Previous studies found a negative correlation between vertebral bone marrow fat (MF) and bone density (BMD). Proposed mechanisms for this include i) a shift in stem cell lineage allocation from osteoblasts towards adipocytes, and ii) an increase in osteoclast-promoting cytokines with greater MF. However, little is known about the relationship between MF and bone markers. To assess these relationships in older adults, we used data from the AGES-Reykjavik cohort. MF was measured...

Standard DXA measurements, including FRAX scores, are limited in assessing fracture risk in type 2 diabetes (T2D). Novel, general applicable biomarkers are therefore needed. MicroRNAs (miRNAs) are secreted into the circulation from cells of various tissues proportional to local disease severity. Serum miRNA classifiers including miR-550a-5p were recently found to discriminate T2D women without and with prevalent fragility fractures with high specificity and sensitivity (AUC&#6...

Introduction: The creatine kinase (CK) is a dimeric enzyme, involved in energetical metabolism. It is present in many tissues, but higher concentration in skeletal and cardiac muscle.Therefore, conditions that involve muscle tissue may increase this serum enzyme. Such enzyme elevation is usually observed in inflammatory myopathies and others autoimmune diseases.Sometimes some elevation in CK is not fully understood out off these co...
