BACKGROUND Calcium supplements increase bone mass in children, but the effect does not persist once supplementation is discontinued. OBJECTIVE The objective of this study was to determine whether milk intake during childhood and adolescence, when controlled for current calcium intake, is associated with adult bone mass (ie, bone mineral content), bone mineral density, and the incidence of ost...

BACKGROUND Female adolescent runners have an elevated prevalence of low bone mass for agemdashan outcome that may be partially due to inadequate energy intake. OBJECTIVE The objective was to evaluate diet, menstrual history, serum hormone concentrations, and bone mass in female adolescent runners with normal or abnormal bone turnover. DESIGN Thirty-nine cross-country runners (age: 15.7 plus...

isolated extramedullary relapse of chronic myelogenous leukemia (cml) after allogeneic stem cell transplant is rare. there is a case report of a child who developed a granulocytic sarcoma of the maxillary and sphenoid sinuses and lumbosacral spinal cord mass 18 months after allogeneic bone marrow transplant for cml. he was presented with per orbital edema and neurological deficit of lower extre...

purpose to date, little is known about the effects of a reduced level of jumping exercise regimens on bone turnover markers and mass. this study investigates the effects of different jumping exercise regimens with varying exercise loads on serum bone turnover markers and bone mass in female rats. methods a total of 144 female rats aged 12 weeks, were divided into 12 groups as follows: no exerci...

OBJECTIVE To compare bone mineral density in patients with juvenile-onset Systemic lupus erythematosus and healthy controls. PARTICIPANTS Serial bone mineral density measurements in 27 patients with juvenile-onset systemic lupus were compared to 97 healthy age-matched controls. RESULTS All patients with juvenile-onset had low bone mineral density scores at initial assessment that progressed...

Osteoporotic fractures are the result of low density and especially inferior bone quality (microarchitecture) caused by both internal (genes, hormones) and external (life style) influences. Bone mechanosensors are extremely important for the overall integrity of the skeleton, because in response to mechanical load they activate its modeling, resulting in an increase in bone density and strength...

2. Albertazzi P, Bottazzi M, Steel SA. Bone mineral density and depot medroxyprogesterone acetate. Contraception. 2006;73:577-83. Abstract: INTRODUCTION: Depot medroxyprogesterone acetate (DMPA) suppresses pituitary gonadotrophin output, thus, suppressing ovulation. Estrogen production from the ovary is also strongly inhibited, and the resulting estrogen deficiency has a detrimental impact on b...

Although increased physical activity early in life is recommended for optimizing bone health, no controlled trials on the effect of activity on bone mass accretion during periods of rapid growth have been reported. The purpose of this study was to determine whether infants randomized to a 1 year gross motor activity program had a greater bone mass accretion than infants randomized to a fine mot...
