We measured histologic indices of bone remodeling and turnover separately on the cancellous, endocortical, and intracortical subdivisions of the endosteal envelope, and on the combined total surface, in transiliac bone biopsies obtained after double tetracycline labeling in 142 healthy women, aged 20-74 years, 34 black and 108 white, 61 premenopausal and 81(More)
The anti-fracture efficacy of sodium fluoride (NaF) was evaluated in 84 postmenopausal white women with spinal osteoporosis. The dose of NaF used was 75 mg/day and all patients in this prospective, randomized, double-blind, placebo-controlled clinical trial received calcium supplements (carbonate salt) 1500 mg/day in addition to participating in a(More)
In our recently completed sodium fluoride (NaF) clinical trial [1] we observed that only about 25% of vertebral deformities, documented by change in vertebral morphometry on radiographs, were associated with corresponding areas of increased isotope uptake on radionuclide bone scans. This was an unexpected finding. In the initial trial design, we had(More)
From a random sample of our institution's health maintenance organization (HMO), we recruited 250 white women and 112 black women, aged 55-75, all of whom were 10 or more years postmenospause with minimal estrogen exposure and free of osteoporosis, other metabolic bone disease, and medical, surgical, or therapeutic situations that may influence bone loss.(More)
There are few published data on bone mass, measured by dual-energy X-ray absorptiometry (DXA), in healthy white or black men. Similarly, a recently described predictor of hip fracture among white women, hip axis length (HAL), has not been studied in men. We recruited 160 white and 34 black men, aged 23-80 years, and screened for diseases and drug exposures(More)
The purpose of this longitudinal study is to describe bone mass and body composition, and the annual changes in these measurements, among third grade students recruited from a suburban school district. Whole body bone mineral content (WBBMC), bone mineral density (WBBMD), fat, and lean mass were measured by dual-energy X-ray absorptiometry. Bone mass in the(More)
We measured indices of bone volume (cancellous, cortical) and bone surface (cancellous, endocortical, and intracortical) in intact full-thickness transiliac bone biopsies obtained from 144 healthy women aged 20-74 (35 black and 109 white, 62 premenopausal and 82 postmenopausal). The data were analyzed by two-way analysis of variance of the four groups(More)
Osteoporosis is characterized by both a low bone mass and a disruption of the architectural arrangement of bone tissue, leading to decreased skeletal strength and increased fracture risk. Although there are well-known ethnic differences in bone mass and fracture risk, little is known about possible ethnic differences in bone structure. Therefore, we studied(More)
OBJECTIVE To test the hypothesis that bone mineral density (BMD) in periarticular subchondral regions of the knee joint is abnormal in patients with osteoarthritis (OA). METHODS Sixty-two knees from patients with relatively mild OA (primarily radiographic grades 0, 1, 2) of the knee were compared with 62 knees from normal subjects matched for age, sex,(More)
BACKGROUND Despite a surge of interest and literature on depersonalization disorder in recent years, a large series of individuals with the disorder has not been described to date. In this report, we systematically elucidate the phenomenology, precipitants, antecedents, comorbidity, and treatment history in such a series. METHOD 117 adult subjects with(More)
