5. Genetic regulation of bone mass and susceptibility to osteoporosis.
Match Strength: 7.252
Osteoporosis is a common disease with a strong genetic component characterized by reduced bone mass and increased risk of fragility fractures. Twin and family studies have shown that the heritability of bone mineral density (BMD) and other determinants of fracture risk-such as ultrasound properties of bone, skeletal geometry, and bone turnover-is high, although heritability of fracture is modest. Many different genetic variants of modest effect size are likely to contribute to the regulation of these phenotypes by interacting with environmental factors such as diet and exercise. Linkage ...

6. Fat embolism syndrome: history, definition, epidemiology.
Match Strength: 7.228
The first clinical case of fat embolism was described over 100 years ago and significant progress has been made in the understanding of this condition since then. Gurd's criteria, consisting of major and minor clinical features, is the most commonly used diagnostic tool in the literature. Due to the lack of a gold standard for diagnosis, clinical criteria cannot be validated. It is now recognized that although fat embolization occurs in the majority of patients with long bone fractures, clinical signs and symptoms occur only in 1-10% of patients with fractures ...

12. Bone fragility: failure of periosteal apposition to compensate for increased endocortical resorption in postmenopausal women.
Match Strength: 5.825
The increase in bone fragility after menopause results from reduced periosteal bone formation and increased endocortical resorption. Women with highest remodeling had greatest loss of bone mass and estimated bone strength, whereas those with low remodeling lost less bone and maintained estimated bone strength. INTRODUCTION: Bone loss from the inner (endocortical) surface contributes to bone fragility, whereas deposition of bone on the outer (periosteal) surface is believed to be an adaptive response to maintain resistance to bending. MATERIALS AND METHODS: To test this hypothesis, changes in ... Read More »

13. Aromatase inhibitors and bone loss.
Match Strength: 5.320
The aromatase inhibitors (AIs) anastrozole (Arimidex), letrozole (Femara), and exemestane (Aromasin) are significantly more effective than the selective estrogen-receptor modulator (SERM) tamoxifen in preventing recurrence in estrogen receptor-positive early breast cancer. Aromatase inhibitors are likely to replace SERMs as first-line adjuvant therapy for many patients. However, AIs are associated with significantly more osteoporotic fractures and greater bone mineral loss. As antiresorptive agents, oral and intravenous bisphosphonates such as alendronate (Fosamax), risedronate (Actonel), ... Read More »

14. Selective estrogen receptor modulators to prevent treatment-related osteoporosis.
Match Strength: 5.138
The intended therapeutic effect of gonadotropin-releasing hormone (GnRH) agonists is hypogonadism, which is a leading cause of osteoporosis in men. Consistent with this observation, GnRH agonists decrease bone mineral density and increase fracture risk in men with prostate cancer. GnRH agonists markedly decrease serum levels of both testosterone and estrogen. Estrogens play a central role in homeostasis of the normal male skeleton, and the available evidence suggests that estrogen deficiency rather than testosterone deficiency accounts for the adverse skeletal effects of GnRH agonists. The ... Read More »

16. Size-corrected BMD decreases during peak linear growth: implications for fracture incidence during adolescence.
Match Strength: 4.692
Peak adolescent fracture incidence at the distal end of the radius coincides with a decline in size-corrected BMD in both boys and girls. Peak gains in bone area preceded peak gains in BMC in a longitudinal sample of boys and girls, supporting the theory that the dissociation between skeletal expansion and skeletal mineralization results in a period of relative bone weakness. INTRODUCTION: The high incidence of fracture in adolescence may be related to a period of relative skeletal fragility resulting from dissociation between bone expansion and bone mineralization during the growing years. ...

17. Proximal humeral fractures: regional differences in bone mineral density of the humeral head affect the fixation strength of cancellous screws.
Match Strength: 4.624
The purpose of this study was to investigate the 3-dimensional trabecular bone mineral density (BMD) in the humeral head and determine the effects of trabecular BMD on the pullout strength of cancellous screws. Five regions of interest (ROIs) were defined in the humeral head (superior- anterior, superior-posterior, central, inferior-anterior, and inferior-posterior). The trabecular BMD of each ROI was determined by use of peripheral quantitative computed tomography. Cancellous screws were inserted in each ROI and cyclically loaded. The superior-anterior ROI had a lower trabecular BMD than all ... Read More »

18. Safety of adjuvant aromatase inhibitor therapy.
Match Strength: 4.602
The long-term effects of aromatase inhibitors (AIs) on lipids and bone and cardiovascular and gynecological health are of particular interest to clinicians. The safety data of anastrozole, letrozole, and exemestane are limited to trials with follow-up periods of 5 years or less, and much of the data arise from comparisons with tamoxifen, a drug that has both estrogen agonist and antagonist effects. With the lack of extensive long-term data, indirect comparisons between the safety profiles of the AIs provide some insights. Although results from these indirect comparisons should be interpreted ... Read More »
