Background: Failure to maintain bone mass density is a major complication in patients with cystic fibrosis (CF). This study was conducted to evaluate the prevalence of low bone mineral density (BMD) and also identifying associated risk factors in CF patients. Materials and Methods: Present study conducted on 59 CF patients aged 5-35 years referred to respiratory clinic of Masih Daneshvari Hospi...

BACKGROUND Fat mass is variably associated with bone mass, possibly due to differential mechanical and biological effects of fat mass. We examined the association of fat mass with bone mass in a lean population. OBJECTIVE To investigate association between hip bone mineral density and fat and lean mass in a cross-sectional study from southern India. DESIGN The Andhra Pradesh Children and Pa...

background: osteoporosis is a disabling disease characterized by compromised bone strength, which predisposes a patient to increased risk of fracture. the aim of this study was evaluation the pattern of bone mass in iranian healthy population. methods: the study was performed between december 2000 and may 2001 on one thousand three healthy iranian sub jects who currently live in tehran. they we...

introduction: osteoporosis and periodontal diseases are both multifactorial and are mostly associated with aging. the aim of this study was to evaluate the relationship between osteoporosis and periodontal diseases. materials and methods: in this analytical/cross-sectional study, periodontal examinations were carried out on 98 women who had undergone bone mass densitometry. of these cases, cons...

Low bone mineral density (BMD) in adolescents with anorexia nervosa (AN) is associated with a low bone turnover state. Osteoprotegerin (OPG), a cytokine that acts as a decoy receptor for receptor activator of nuclear factor-kappaB ligand, decreases bone resorption by inhibiting differentiation of osteoclast precursors and activation of mature osteoclasts, and by stimulating osteoclast apoptosis...

Osteoporosis is a disorder characterized by reduced bone strength, diminished bone density, and altered macrogeometry and microscopic architecture. Adult bone mass is the integral measurement of the bone mass level achieved at the peak minus the rate and duration of subsequent bone loss. There is clearly a genetic predisposition to attained peak bone mass, which occurs by a person's mid-20s. Bo...

A strong emphasis has been placed on the effects of sports on bone mass and possibility of preventing future osteoporosis1, considering that strenuous physical exercise plays a crucial role in the bone mass gain process2. The load mechanisms from the exercises increase bone mineral density, regardless or gender and age of those who practice them3. Bone tissue dynamically responds to the imposed...

background different clinical and epidemiological studies using dual-energy x-ray absorptiometry have shown an increased prevalence of low bone mineral density in patients with inflammatory bowel diseases.the aim of this study was to assess the correlation between bone density and the disease activity in patients with ulcerative colitis. methods in this cross-sectional study, 52 patients with u...
