Association between allopurinol use and hip fracture in older patients discharged from rehabilitation

Basu Ujani , Goodbrand James , McMurdo Marion , Donnan Peter , McGilchrist Mark , Frost Helen , George Jacob , Witham Miles

Background: Allopurinol reduces oxidative stress and interacts with purinergic signalling systems important in bone metabolism and muscle function. We assessed whether allopurinol use was associated with a reduced incidence of hip fracture in older people who had undergone rehabilitation.Methods: Analysis of prospective, routinely-collected rehabilitation and hospitalisation data. Data on patients discharged from a single inpatient geriatric rehabilitati...

Endochrondral ossification, mesenchymal stem cell and Wnt pathway specific loci predict differential skeletal effects in high bone mass

Gregson Celia , Kemp John , Marshall Mhairi , Smith George Davey , Brown Matthew , Duncan Emma , Tobias Jon

Extreme high bone mass (HBM) may be monogenic (e.g. LRP5 mutations) or polygenic, due to variants in the same genes determining bone mineral density (BMD) as found in the general population. We aimed to determine how variation in established BMD loci, in different functional pathways, explains the HBM phenotype.241 unexplained HBM cases (lumbar spine(LS)1+total hip(TH) Z-scores≥+4.4) were recruited from 15 UK centres, by screening...

History of meconium ileus affects bone health and body composition in young patients with cystic fibrosis

Doulgeraki Artemis , Petrocheilou Argyri , Chrousos George , Petrocheilou Glykeria , Monopolis Ioannis , Doudounakis Stavros-Eleftherios , Kaditis Athanasios

Objective: Growth of patients with cystic fibrosis (CF) and meconium ileus is frequently compromised. The aim of this prospective study was to evaluate body composition in this particular group of patients. We hypothesized that history of meconium ileus could predict suboptimal growth, bone, muscle and fat mass, irrespective of other prognostic factors for CF.Methods: CF subjects were investigated over a 3-year period. Their medical records were reviewed...

Loss of the longevity gene SirT1 dysregulates chondrocytes and leads to an arthritic phenotype in vivo, via impaired autophagy

Sacitharan Pradeep Kumar , Zarebska Jadwiga , Gharios George Bou , Vincent Tonia , Edwards James

Ageing is universally linked to skeletal deterioration. Common mechanisms may control both processes, where dysregulation may predispose to bone loss and osteoarthritis (OA). The epigenetic modifier SirT1 controls lifespan and decreases with age. However, the role of SirT1 in joint disease is unclear. Human tissue samples, novel genetically modified mice, a surgical disease model and advanced cellular and molecular studies were employed to explore the hypothesis that SirT1 is ...

Treatment outcomes during teriparatide use in Greece: country sub-analysis of the Exfos Observational Study

Aloumanis Kyriakos , Savvidis Matthaios , Repousis Alexandros-Paris , Lianou Helen , Drossinos Vangelis , Kapetanos George

Scope: Extended Forsteo Observational Study (ExFOS), a multinational, non-interventional, prospective, observational study aims to evaluate fracture outcomes, back pain (BP), compliance and health-related Quality of Life (QoL) in osteoporotic patients prescribed teriparatide (TPTD). We present treatment outcomes for patients (male or female) treated for up to 24 months in Greece.Methods: Of the 440 patients enrolled in the study 416 (mean age 69.9±9...

Chronic intermittent torticollis in a toddler: a rare case of axis (C2) Ewing sarcoma presentation

Papadakis Vassilios , Vlachopapadopoulou Elpis , Antoniadi Kondylia , Tzotzola Vassiliki , Nikas John , Stefanaki Kalliopi , Sfakianos George , Polychronopoulou Sophia

Background: Torticollis in toddlers is most frequently a manifestation of traumatic atlantoaxial rotatory displacement or oropharyngeal inflammation, and rarely due to retropharyngeal abscesses and pyogenic cervical spondylitis. Rarely, intermittent torticollis may be caused by posterior fossa tumors. A very rare case of chronic intermittent torticollis due to upper spine Ewing sarcoma is presented.Presenting problem: A 2.2 year-old girl suffered four ep...

Prevalence of FRAX clinical risk factors: dietary calcium intake habits and osteoporosis screening in Greek women

Bakides Sofoclis , Sakellariadis George , Alevizou Stavroula , Koussi Kleoniki , Rapti Anna , Tsiverdis Panayiotis , Kavvadia Konstantina , Drivas Kyriakos , Ververeli Charilila-Loukia

Introduction: Osteoporosis-related fractures can cause substantial disability and increase health care costs, and mortality. There are many difficulties to access Greek women residing in remote villages and perform the FRAX tool for osteoporosis evaluation, especially, after the global economy crisis.Purpose: To estimate the prevalence of FRAX clinical risk factors, calcium intake habits and perform osteoporosis screening in 275 postmenopausal Greek wome...

What happens to the skeleton at the time of diagnosis of paediatric cancer?

Doulgeraki Artemis , Nikita Maria , Kanaka-Gantenbein Christina , Baka Margarita , Karavanaki Kyriaki , Athanasopoulou Helen , Polyzois George , Tsentidis Charalampos , Kossiva Lydia

Objectives: To evaluate the skeletal profile of paediatric patients with cancer at diagnosis.Methods: Children diagnosed with cancer in our Oncology Centre were recruited during a fifteen-month period and underwent metabolic bone profile and dual-energy X-ray absorptiometry (DXA) at the time of diagnosis. Subsequently, they were divided in two subgroups, according to diagnosis; haematological malignancy vs solid tumour. For comparison, a group of 38 sex ...

A GWAS in an extreme high bone mass population shows excess signal from genes associated with BMD in the normal population

Gregson Celia L , Leo Leo Paul J , Clark Graeme R , Smith George Davey , Brown Matthew A , Tobias Jon H , Duncan Duncan Emma L

Extreme high bone mass (HBM) may be monogenic (e.g. due to mutations in SOST or LRP5) or polygenic, due to variants in the same genes determining bone mineral density (BMD) as found in the general population. We aimed to determine the genetic cause underlying HBM in an extreme HBM population.258 unexplained HBM cases (defined as L1 Z-score ≥+3.2 plus total hip Z-score ≥+1.2, or total hip Z-score ≥+3.2 and L1 <...
