Bone Abstracts

Chronic kidney disease in children causes multiple bone alterations, particularly renal osteodystrophy, which affects both bone quality and size, in turn causing short stature, bone deformities and brittleness. Once they get a transplant, this process starts to revert, and although mineral alterations improve, short stature often requires growth hormone supplementation but bone fragility requires evaluations in order to revert the disease’s effects. DXA is a valuable tool...

Objective: The purpose of this study was to verify the influence of age, body mass and stature on the functionality level of children with Osteogenesis Imperfecta (OI). METHODS: Thirty-eight children (8.21±4.26 years, 19 girls and 52.6% OI type III) were evaluated during their hospitalization for Pamidronate intravenous infusion in the Brazilian Midwest reference hospital for OI treatment (University Hospital of Brasília). Body weight and stature were measured and ca...

Objective: To characterize a group of children with Osteogenesis Imperfecta (OI) followed up at the University Hospital of Brasília (HUB), Brazil.Methods: Data were collected with children and adolescents that were hospitalized in the HUB for intravenous pamidronate infusion treatment. This hospital is an OI reference center of the Midwest region in Brazil. The sample consisted of thirty-eight subjects, of which 50% were female. 52% of the children ...

Objectives: This study aimed to correlate handgrip strength and functionality of children with Osteogenesis Imperfecta (OI).Methods: Thirty-eight children and adolescents with different types of OI were single-timed evaluated during their hospitalization for pamidronate intravenous infusion at the University Hospital of Brasília, Brazil. This hospital is the Brazilian Midwest reference for OI treatment through the national health system. These child...

Aim: Periodontologists all over the world are more and more interested in connection between pathogenesis of aggressive periodontitis (AP) and calcium and vitamin D metabolic disturbances. Vitamin D besides its direct effect on calcium homeostasis, has immunomodulatory action, that makes interesting the study of vitamin D effect on pathogenesis of AP.Materials and methods: We studied 102 (49 males; 53 females) patients with AP (40.32±1.13), 42 patie...

Objective: Turner syndrome (TS) is a chromosomal aberration characterized by total or partial loss of one of the two X-chromosomes, and affects about 1 in every 2500 girls. TS patients can develop the bone disease with decreased bone density and selective reduction in cortical bone thickness, which probably contributes to the increased fracture risk. However, the mechanisms underlying the bone disease remain poorly understood. Thus, the aim of this study was to investigate the...

: This study analyses the long-term effect of rhGH on final height (FH) and bone health in renal transplanted patients.Twenty-one young adult patients, aged 17–26 years, were studied. Group A consisted of 15 patients (12 boys) who received rhGH during 3.0 years before transplantation. After transplantation three boys needed rhGH again for 3.5 years. In group B six patients (three boys) didn’t need rhGH before transplantation, three girls receiv...

Autoimmune hepatitis (AIH) is an immune-mediated chronic inflammatory disease of the liver of unknown origin, that suddenly appears in previously healthy, normally growing children. Standard therapy is long-term prednisone, aimed at avoiding progression to cirrhosis. Considering the inflammatory origin of the disease and the long-term steroid therapy, negative consequences for bone health can be expected, but no data on this complication have been published until now.<p cl...

Introduction: Denosumab monoclonal antibody approved for Osteoporosis’s treatment in Europe union and U.S.A. Dose of 60 mg every 6 months reduces the risk of vertebral, non vertebral and hip fractures. What is more increases BMDMaterial and methods: Descriptive observational study with densitometric characterisques and risk factors of 64 patients in Osteoporosis unit of HGUG Marañón from November 2011 to December 2013. Analyzing occurrence...

Background: Trisomy 9p is a rare abnormality caused by duplication of the short arm of chromosome 9. Translocation t(9;11) is a rarer variant. Both anomalies are compatible with long survival. Clinical manifestations are very variable, and include short height, mental retardation, hypertelorism, strabismus, foot/hand anomalies, delayed bone maturation. Low bone mineral density (BMD) or fragility fractures have never been reported.Presenting prob...
