simple bone cysts are usual, benign, fluid-filled, cystic lesions that often occur in the metaphysis of the long bones and are rarely detected in vertebrae. a case of a simple bone cyst in the body of the fifth lumbar vertebra in a 28-year-old woman with complaint of intermittent low back pain is described. according to the radiologic findings, the lesion was detected as a simple bone cyst, and...

introduction: low level laser therapy (lllt) also known as photobiomodulation, is a treatment that uses low-level lasers or light-emitting diodes (leds) to change cellular function and is a clinically well accepted tool in regenerative medicine and dentistry. considering the variety of laser, exposure, cells and study types, the exact effects of low level laser therapy seems to be unclear. the ...

  Background: Osteoporosis, or porous bone, is a disease characterized by low bone mass density (BMD) and structural deterioration of bone tissue, leading to bone fragility and increased risk of hip, spine, and wrist fractures. There are numerous risk factors for osteoporosis. While many of these factors are non-genetic in nature, there is a definite genetic component responsible for this condi...

osteoporosis is a skeletal disease characterized by reduction in bone mass and micro architectural changes in the bone, which leads to increased bone fragility. the gold standard for the diagnosis of osteoporosis is the measurement of bone mineral density (bmd) by dual energy x-ray absorptiometry (dxa). periodontal disease is a chronic destructive disease which can occur in adults, young people...

introduction:there is considerable amount of controversy about the long term effects of multiparity and duration of breast-feeding on maternal bone mineral density after menopause. this study was conducted to determine whether multiple pregnancy and prolonged duration of breast-feeding are independent predictors of low bone mass in post-menopausal kurdish women. methods: in a retrospective stud...

using a cluster sampling method, a group of menopausal women from three geographic areas in tehran were asked to participate in the study. demographic data was obtained using a questionnaire. subjects were than referred to perform bone mass densitometry (bmd). the relationship between various variables (i.e. age of menarche, number of years of endogenous estrogen exposure, ... ) with mineral de...

The present study aimed to investigate the imaging characteristics of primary malignant bone tumors in children. The imaging results of 34 children with primary malignant bone tumors confirmed by histopathological diagnosis between March 2008 and January 2014 were retrospectively analyzed. In total, 25 patients had osteosarcoma, with radiography and computed tomography (CT) showing osteolytic b...

Osteoporosis has been previously defined in 1993 as a disease characterized by low bone mass and microarchitectural deterioration of bone tissue leading to enhanced bone fragility and a consequent increase in fracture risk. This definition has been revised in 2001 as a skeletal disorder characterized by compromised bone strength with an increased risk of fracture. The reason for the revision is...

BACKGROUND To identify factors that predict low bone mineral density (BMD) in pediatric patients referred for dual-energy x-ray absorptiometry assessments. METHODS This is a retrospective cohort study of 304 children and adolescents referred for dual-energy x-ray absorptiometry assessments at a tertiary care center. Outcomes included risk factors which predicted a significant low bone density...
