Objective: Patan, is a semi urban area in Gujarat, India where fluorosis is endemic (Fluoride concentration in ground water 1.96–10.85 ppm, Patel et al., 2008). Exposure to fluoride is likely to be higher in lower socio-economic class (SEC) due to lack of access to bottled water. Calcium intake and vitamin D status may modify fluorine absorption. Therefore, the aims of this study were to examine: i) prevalence of dental and skeletal fluorosis in children from upper, middl...

Objective: Bone is one of endocrine organ and osteocytes secretes FGF23, Sclerostin and DKK1. FGF23 inhibits renal phosphate reabsorption and suppresses 1-α hydroxylase activity. Calcitriol stimulates FGF23 synthesis in bone. We aimed to determine the effect of single bolus injection of vitamin D on serum FGF23, DKK1 and Sclerostin concentrations in vitamin D-deficient subjects.Design and methods: The study group was composed of placebo group with s...

Background: On cessation of bisphosphonate treatment, while bone mineral density decreases slowly, bone resorptive markers such as C-terminal telopeptide (CTX) increase more quickly and may be useful in monitoring ‘offset’ of action. Our aim was to analyse changes in CTX on stopping long-term bisphosphonate treatment to guide clinical decision-making on the duration of treatment cessation (‘drug holidays’).Subjects and methods: A tota...

Background: The presence of vascular calcification (VC) is a predictive factor for the development of cardiovascular diseases, especially in the obese population. VC has also been inversely associated with bone mineral density (BMD) but the results have been inconsistent. The main aim of this study was to evaluate the associations between VC, obesity and volumetric BMD (vBMD).Methods: We studied 148 healthy men and women, aged 55–75 years, divided i...

Introduction: Osteogenesis Imperfecta (OI) in children has been treated with different types of biphosphonates between which Pamidronate has been the most used. Zolodronic acid has shown igual efficacy, but few studies have used ibandronic acid infusion in children.Objective: To show efficacy and safety of ibandronic acid infusión in preventing fractures in children with OI.Methods: 12 children with ages between 2 and 6 years ...

Objectives: To compare and contrast the natural history of osteoporosis and response to zoledronate in children and adolescents with Duchene muscular dystrophy (DMD), spinal muscular atrophy (SMA) or other congenital muscular dystrophies (CMD).Methods: A retrospective medical record review of fracture history, treatment and bone mineral densitometry of children managed at a tertiary centre in Sydney over the last 6 years.Results: A...

The aim of this study was to evaluate the trabecular bone score (TBS), bone mineral density (BMD) and body composition in men of various ages.Materials and methods: 300 men aged 40–87 years (mean age – 60.5±0.6 years; mean height – 1.61±0.003 m; mean weight – 84.1±0.9 kg) were examined. The patients were divided into the following age-dependent groups: 40–49 years (n=52), 50–59 years (n=90), ...

The aim of this study was to evaluate the trabecular bone score (TBS), bone mineral density (BMD) and body composition in women of various ages.Materials and methods: 494 women aged 41–89 years (mean age, 63.6±0.4 years; mean height, 1.61±0.003 m; and mean weight, 74.0±0.6 kg) were examined. The patients were divided into the following age-dependent groups: 40–49 years (n=35), 50–59 years (n=130), 60–6...

Background: Pediatric hypoparathyroidism is an orphan disease. Conventional management combines native and active vitamin D, calcium supplementation and sometimes phosphate binders. The use of teriparatide has been reported both in adults (daily or bi-daily subcutaneous infusions) and in children (rather continuous subcutaneous infusion) as second-line therapy.Methods: We present as median (min-max) the results of a retrospective single-centre review of ...

Objectives: Synovial fluid glutamate concentrations increase in various arthritides. Activation of kainate (KA) and AMPA glutamate receptors (GluRs) increase interleukin 6 (IL6) release and cause arthritic pain respectively. GluR antagonists represent potential peripheral treatments for inflammatory arthritis and inflammatory mechanisms that contribute to osteoarthritis (OA). We hypothesised that AMPA and KA GluRs are expressed in arthritic joint tissues and that peripheral ad...
