Type 2 diabetes is associated with fracture risk but, paradoxically, greater bone mineral density. The trabecular bone score (TBS) has been proposed as an index of bone microarchitecture associated with bone quality. This study compared the performance of TBS, bone mineral density (BMD), original and TBS adjusted FRAX scores in the prediction of vertebral fractures (VFs) in diabetic patients. This cross-sectional study enrolled 169 Korean postmenopausal diabetic women. Lateral...

Children and adolescents with inflammatory bowel disease (IBD) have defects in bone mineral density (BMD) and bone structure that do not completely normalize with clinical remission.The objective of the study was to determine bone turnover marker (BTM) concentrations and factors behind altered bone metabolism in a case-control setting.We measured the bone formation marker PINP and bone resorption markers CTX and TRACP5b in 42 adole...

Objectives: To establish the correlations between the body composition, somatotypes and average bone mineral density (BMD) and bone mineral content (BMC) in young (17–18 y.o.) male living in Donbass region (Ukraine).Materials and methods: Anthropometric and skinfold measurements were carried out. Estimations of the calcaneal BMD (g/cm2) and BMC, (r), estimated on ALOKA-5.0 DXA machine among 156 male were done. Total body fat perc...

We analyzed body composition (DXA, Hologic) in 334 young patients (aged 3–24 years) with chronic diseases, most of them on long-term glucocorticoid (GC) treatment, and monitored its changes over 3–14 years (6.9±6.2 years).Bone mineral content (BMC), fat mass (FM) and fat-free mass (FFM) were measured on total body (TB), trunk, upper limbs, lower limbs. BMC, FM, FFM were expressed as percentages and compared with age- and sex-matched health...

Objective: The incidence of eating disorders has increased in 15–19 years old1. There is growing concern as to its impact on bone health during adolescence where peak bone mass acquisition is of paramount importance. This paper describes bone size and size adjusted bone mineral content in an adolescent/young adult eating disorder population.Methods: A total of 68 patients (63 F/5 M, 90% anorexia nervosa and 10% atypical eating disorder), ...

: 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...

We performed a prospective study on 440 young patients (aged 3–20 years), affected by various chronic diseases (cystic fibrosis; juvenile idiopathic arthritis; nephrotic syndrome; systemic lupus erythematosus; Duchenne muscular dystrophy; autoimmune hepatitis; transplants; etc.), with periodical bone mineral density (BMD) evaluations with DXA, for 3–14 years (7.8±6.2).266 patients were on long-term treatment with glucocorticoids (GCs); amo...

In this study, the effect of food restriction of 30% in calorie intake on femurs of rats of different ages was investigated. Male Rattus novegicus albinus rats, Holtzman lineage, aged 38 days, 4 and 16 months were used. The animals were divided into six groups (n=8–10 per group), three being control groups (C38, C4 and C16) and three groups on restricted diet (R38, R4 on R16). The restricted animals were submitted to food restriction of 30% being fed wit...

Background: Hypophosphatasia (HPP) is a rare skeletal disease characterized by defective bone and teeth mineralization and the deficiency of tissue non-specific alkaline phosphatase activity. This disorder is caused by mutations in the ALPL gene, which encodes TNAP. The clinical presentation of HPP varies greatly, ranging from stillbirth without bone mineralization (perinatal form) to findings in later life, such as delayed walking, short stature, skeletal deformities, bone pa...

Purpose: The purpose of this study is to analyse regional differences in the microstructural and mechanical properties of the distal femur depending on osteoarthritic changes using micro-images based on finite element analysis.Materials and methods: Distal femur specimens were obtained from ten donors composed of ten women with OA (mean age of 65 years, ranging from 53 to 79). As controls, the normal distal femur was sampled from age and gender matched d...
