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...

Purpose: The aims of this study were (1) to assess the topographical and chemical changes of Ca and Mg ion implantation procedures using plasma immersion ion implantation and deposition (PIIID) technique and (2) to evaluate cellular response of human bone marrow-derived mesenchymal stem cells (hBMMSCs) to Ca and Mg ion-implanted titanium surface, compared with resorbable blast media (RBM)-treated titanium surface by observing cell attachment, proliferation and gene expression ...

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...

The impact of sex and maturation on trabecular (Tb) and cortical (Ct) microarchitecture in children and young adults has not been well established. The new second-generation high-resolution peripheral quantitative CT (HR-pQCT) scanner (XCT II, Scanco Medical) incorporates three important advances to provide greater spatial resolution, direct measures of Tb thickness and spacing and measures in the Ct midshaft. The aim of this study was to identify sex and maturation effects on...

Objectives: Within the National Health Service there is a recognised need for supporting young peoples transition into adult services1. Focus groups and forums have historically been used to identify how to achieve ‘good’ transition between services, from the perspective of patients, carers and professionals. A recent article recommended an individualised programme supporting transition for young people with osteogenesis imperfecta (OI)2. The ai...
