introduction : acute lymphoblastic leukemia (all) and non-hodgkin's lymphoma (nhl) are the most common malignancies in children and adolescents. therapies such as corticosteroids, cytotoxic and radiotherapy will have harmful effect on bone mineral density (bmd) which can lead to increased possibility of osteoporosis and pathological fractures. subjects and methods: this 3-year cross-sectional s...

OBJECTIVE This study was designed to prospectively examine differential effects of sustained "high" and "low" serum prolactin levels on bone mineral density and peripheral markers of bone metabolism. METHOD A dual-energy X-ray absorptiometer was used to measure bone mineral density. Peripheral markers of bone formation and resorption were used to measure bone metabolism in 14 Caucasian female...

Malnutrition, particularly protein undernutrition, contributes to the occurrence of osteoporotic fracture by lowering bone mass. In this study, the effects of dietary protein on bone mineral density and body weight in protein undernutrition were compared between gelatin and milk casein. When mice were fed for 10 wk with a low protein diet containing 10(%) casein or 6% casein +4% gelatin, there ...

CONTEXT Calcium Nephrolithiasis is a multifactorial disease; in its pathophysiology is involved various minerals and metabolic factors that may be altered, including bone and phosphor-calcium metabolism. OBJECTIVE To establish the scientific evidence and demonstrate the relationship between calcium nephrolithiasis and bone mineral density loss, through the use of bone turnover markers, serum ...

1. The influence of pregnancy, lactation and weaning on bone mineral density in healthy women was investigated during a 2 year prospective study of 59 pregnant and lactating women from the 18th week of gestation. 2. Bone mineral density was measured by dual energy X-ray absorptiometry at the non-dominant radius ultra distally and more proximally in the 18th and 37th weeks of gestation, and 0, 3...

Myelomeningocele causes serious locomotor disability, osteoporosis and pathologic fractures. The aim of this study was to investigate the relationship between body composition, bone mineral density, walking ability and sport activity in myelomeningocele children. 60 patients aged between 5 and 14 yrs with myelomeningocele (22 ambulatory and 38 non-ambulatory), were studied. Fat mass and fat-fre...

BACKGROUND Studies from high income countries (HIC) have generally shown higher osteoporotic fracture rates in urban areas than rural areas. Low bone mineral density (BMD) increases susceptibility to fractures. This review aimed to assess whether urbanicity is consistently associated with lower BMD globally. METHOD Ovid MEDLINE, EMBASE, and Global Health (-April 2013) were searched for articl...

OBJECTIVE To estimate how axial rotation of lumbar vertebrae quantitatively affects bone mineral density, as measured by dual energy X-ray absorptiometry in the anteroposterior plane. DESIGN Observational study. SETTING University teaching hospital, Hong Kong. PATIENTS Cadaver lumbar vertebrae (L2 to L4) were removed from four adults. MAIN OUTCOME MEASURES Using dual energy X-ray absorp...

Chronic use of systemic glucocorticoids results in progressive bone loss and pathologic fractures. This study identified the predictive variables for bone loss and used peripheral quantitative computed tomography (pQCT) to measure changes in cortical and trabecular bone in patients receiving systemic glucocorticoid therapy of prednisone 15.4 g. Eighty-four asthmatic patients were included in th...

Age at menopause has been found to be associated positively with bone mineral density, and age at menarche has been found to be associated negatively with bone mineral density. However, there have been few studies on the relations of timing of menopause and length of the reproductive period with bone mineral density. The purpose of this study was to examine the relations of timing of menopause ...
