Question: What is the effect of cyclic pamidronate administration on osteoporosis in children with β-thalassemia major? Finding: The dual-energy x-ray absorptiometry scan findings of children with β-thalassemia major and osteoporosis were improved after pamidronate administration. Meaning: Cyclic pamidronate effectively treated osteoporosis in children with β-thalassemia major. |
Question: Does steroid use for 2–6 weeks in children affect bone mineral content (BMC) or density (BMD)? Finding: Steroid use for 2–6 weeks significantly decreased BMC and BMD of the whole body, total body less the head, lumbar spine, and distal radius. A significant negative correlation was observed among BMD, duration, and cumulative dose. Meaning: Steroid use for 2–6 weeks in children negatively affected BMC and BMD. |
To compare different regimens of vitamin D with respect to its serum increment levels and bone mineral accrual in vitamin D-deficient children. Children identified as being vitamin D deficient (serum levels<20 ng/mL) were divided into 3 treatment groups by stratified block randomization (group 1, 4,000 IU/day of vitamin D3 plus 50 mg/kg/day calcium for 12 weeks; group 2, 30,000 IU/wk of... |
As chemotherapy and other sophisticated treatment strategies evolve and the number of survivors of long-term childhood cancer grows, the long-term complications of treatment and the cancer itself are becoming ever more important. One of the most important but often neglected complications is osteoporosis and increased risk of fracture during and after cancer treatment. Acquisition of optimal peak bone mass and... |
Peak bone mass is established predominately during childhood and adolescence. It is an important determinant of future resistance to osteoporosis and fractures to gain bone mass during growth. The issue of low bone density in children and adolescents has recently attracted much attention and the use of pediatric dual-energy X-ray absorptiometry (DXA) is increasing. The process of interpretation of pediatric... |
Purpose : Inhaled corticosteroids (ICS) are used as first-line agents for the treatment of persistent asthma; however, their use is accompanied by apprehension of potential systemic adverse effects. This study aimed to assess the effects of ICS on bone mineral density (BMD) and bone metabolism in children with asthma. Methods : From February 2008 to September 2008, 26 asthmatic children treated... |
Purpose : Long-term administration of anticonvulsants in children with epilepsy may cause short stature, hypocalcemia and low bone mineral density. This study was performed for the early detection of abnormal bone metabolism in children with epilepsy on taking anticonvulsants. Methods : Thirty children aged 5 to 16 years who were diagnosed with epilepsy were enrolled in this study. All had taken... |
Purpose : Dynamics of bone mineral density(BMD) and bone metabolism in children and adolescents with hyperthyroidism have not been thoroughly investigated. The aim of this study was to study how the improvement of thyroid function with antithyroid treatment influenced bone metabolism and BMD in children and adolescents with hyperthyroidism. Methods : Serum levels of osteocalcin(OC), bone-specific alkaline phosphatase(b-ALP), and carboxyterminal telopeptide... |
Purpose : Long-term administration of anticonvulsants for children with convulsive disorder may cause osteomalacia, depending on dosage, duration, types, and combination of anticonvulsants administered. This study was performed to examine the effect of anticonvulsant drugs on bone mineral density in epileptic children. Methods : Forty-eight epileptic children aged 3 to 15 years were enrolled in this study. They were treated with... |
Purpose : Long-term steroid therapy for various glomerular disorders in children has been known to decrease serum Vit D3 level and develop osteomalacia. The aim of this study was to observe the effect of long-term steroid therapy on growth and bone density in children with nephrotic syndrome. Methods : Bone density of 17 steroid-treated nephrotic syndrome was compared with that of... |
Purpose : Estrogen deficiency causes sexual infantilism in Turner syndrome, which could decrease the bone mineral density(BMD) since birth. This decreased BMD might be contributed by the decreased growth hormone(GH) secretion. To improve the decreased BMD, estrogen therapy is recommended, especially after the pubertal age, but estrogen therpay during childhood can accelerate the epiphyseal fusion, resulting in shorter final height. There is... |
Purpose : Osteoporosis and growth failure have been known one of the serious side effects of corticosteroid therapy especially in children. This study was designed to evaluate the effect of long-term administration of steroids on bone mineral density(BMD) in children with nephrotic syndrome and its relationship to cumulative steroid dose, the duration of the rapy and sex. Methods : The BMD of... |
Bone mineral densitometry is a useful procedure for the early detection of metabolic bone diseases and bone density changes caused by long term drug use. Dual energy X-ray absorpt- iometry(DEXA), a recently developed diagnostic radiologic method for evaluating bone mineral density is widely used because of its high sensitivity, easily obtaine results. and low dose radi- ation exposure. The study... |
The long term administration of anti-convulsants on children with convulsive disorders may cause osteomalacia, depending on the dosage, duration, type and combination of anti-convulsants administred. Fifteen children, comprising 10 male and 5 female, dignosed with convulsive disorders and administered with phenobarbital for a long term period of more than 9 months but less than 84 months and 15 healthy children... |
Purpose : This study was conducted to evaluate that long term glucocorticoid treatment in children with the nephrotic syndrome can produce a significant loss of bone mass by measuring of bone mineral density(BMD) Methods : We measured BMD at lumbar vertebra(L2-L4) using dual enegy X-ray absorptiom-etry in 36 patients with the nephrotic syndrome who were administered prednisolone over 6 months and... |
