Anorexia nervosa (AN) is an eating disorder characterized by severe undernutrition. Osteopenia is a frequent, often persistent complication of anorexia nervosa (AN) in adolescent girls and occurs during a critical time of bone development. To determine the impact of chronic undernutrition on bone mineral accrual we measured bone mineral density by dual energy x-ray absorptiometry, bone metabolism markers and leptin levels in AN patients (n=19, age 22.67±1.9 years...

Aim: To assess the relationships of serum osteoprotegerin (OPG), receptor-activator of nuclear factor-κB ligand (RANKL) and tumor necrosis factor-alpha (TNF-α) superfamily with bone composition in end-stage COPD.Methods: Body and bone composition, serum OPG, RANKL, TNF-α and its receptors (sTNFR I, sTNFR II), TNF-related apoptosis-inducing ligand (sTRAIL) levels were measured in 48 men end-stage COPD accepted for lung transplantation, and ...

Objective: We have observed sex-specific effects of pregnancy calcium carbonate supplementation in 8–12 year old Gambian children, indicating slower growth after infancy in girls born to calcium-supplemented mothers but faster in boys.1,2 IGF-1 is a key driver of growth and is responsive to calcium supplementation.3 The aim of this study was to determine whether the pregnancy supplement had resulted in sex-specific effects on mid-childhood IGF1 of th...

Purpose: The aim of this study is to determine the chemical information in trabecular bone by Raman spectroscopy in the human distal femur at the microstructural level.Methods: The subchondral trabeculae were obtained from the middle of medial articular surface of the distal femurs in the two cadavers (one is with and the other is without OA). Raman spectroscopy, a non-destructive technique, was employed to determine the chemical information of the trabe...

Background: Although both testosterone and estrogens are considered essential for normal bone growth, epiphyseal maturation and bone mass accrual during adolescence, only very few data concerning the changes of estrogens, bone maturation, bone mineral density (BMD) and bone geometry in healthy boys at different pubertal stages have been published.Objectives: This study aimed to analyze the relationship between sex steroids and more especially estrogens a...

Aim: To determine the response to treatment, clinical and instrumental features in children with partial GH deficiency (pGHD) and severe GHD (sGHD).Methods: We examined retrospectively 30 children with isolated GHD (stage on Tanner 1) in the Endocrinological department of University hospital (Minsk) over 2004–2012 years. Group 1 (G1) – children with pGHD (n=5) mean±S.D., age 6.3±1.4 years; group 2 (G2) – s...

Objectives: Evaluation of influence the structural and functional condition of bone tissue on caries intensity in adolescents living with deficient of fluoride in drinking water (<0.4 mg/l).Methods: It was examined 200 school children (12 and 15 years old) living in Transcarpathian region.Oral examination was done to determine caries intensity in the subjects (DMFT-index). Bone quality was determined using quantitative ultrasou...

The link between scoliotic deformity and bone metabolism in adolescent idiopathic scoliosis (AIS) has not been well researched. Moreover, the data concerning the cross-talk between leptin level and bone markers in this group of patients are lacking. The objective of this study was to correlate the extent of scoliotic-curve severity with the bone turnover and leptin level in girls with AIS. The study encompassed 77 AIS girls, aged 14.7±2.17 years. Scoliotic curve severity ...

Objective: The study evaluated the efficacy of the therapeutic compliance in brittle bone disease applied to frail elderly people affected by osteoporosis and in treatment with Denosumab.Methods: We studied people ≥75; 43 women (mean age 83±3) and 14 men (mean age 85±3), all suffering from femoral osteoporosis T-score <−4. In 34 women and 6 men, we discovered 1–2 vertebral fractures. They have been treated with Den...
