: 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...

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...

Background: Recently, the prevalence of osteoporosis and sarcopenia in the elderly has dramatically increased. However the relationship between theses disease is not clear.Object: We aimed to determine the independent relations of muscle mass to osteoporosis (femur neck) in relation to body weight, fat mass, and other confounders.Design: We analyzed body composition and BMD data of 570 males and 734 females who are older than 65 ye...

Objection: We compared T-scores of each femoral neck and trochanteric area in the neck fracture patients (NFP) and intertrochanteric fracture patients (IFP). Our hypothesis is that T-score of neck portion in NFP is lower than T-score of neck portion in IFP, and vice versa. We evaluate how FRAX probability is meaningful and sensitive in hip fracture patients.Meterials and methods: From April, 2003 to September, 2012, 18...

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...

Peak bone mass, typically reached in the third decade, is the highest bone mass acquired after completion of normal growth. Attaining a higher young adult bone mass may contribute to a lower risk of fragility fractures later in life. Few studies have specifically investigated quantitative ultrasound (QUS) in relation to peak bone mass in young adult women. The study objectives were to describe normative QUS values for 25 year old women and how extremes of body weight relate to...

The relationships between insulin resistance and BMD are not clear. Therefore, we conducted a cross-sectional study to examine the relationship between insulin resistance and BMD among Korean young adult population. This study is based on the Korea National Health and Nutrition Examination Survey (KNHANES) from 2008 to 2010. BMD and body composition were measured by DXA method. Insulin resistances were obtained by HOMA-IR equation. The relationship between BMD and HOMA-IR were...

Objectives and methods: Exercise induces greatest bone gains during growth, yet reduced bone strength is an age-related phenomenon. This raises the question of whether exercise-induced bone changes when young persist into adulthood. Previous work has suggested exercise-induced gains in bone mass are lost with aging. However, exercise during growth primarily influences bone structure rather than mass to increase strength and mechanisms exist for the maintenance of exercise effe...
