Answer from Dr. Gruber The answer to your question is not entirely known, although certain factors probably contribute. First however, it is important to recognize that the data indicate that among Asians the rate of hip fractures varies considerably whether one is speaking of Japanese, American-Asians, Koreans, New Zealand, Hawaii, etc. In general, Asian women have higher fracture rates than African-Americans but lower than Caucasians. Presumably racial and ethnic influences on risk for developing osteoporosis and fragility fractures depends on (undefined) genetic factors which govern bone mass, geometry, and size of bones (all contributing to strength), bone turnover rates, overall body composition (both muscle mass and fat lessen fracture rates), and calcium metabolism. In addition, lifestyle issues such as physical activity, smoking, etc. probably play a role although this has not been well studied in terms of its relationship to race and ethnicity. In summary, a wide range in fracture incidence worldwide suggests that many factors enter into the determination of skeletal health. Bone mass itself (i.e., bone density) is only a portion of the risk profile.

We need to define shift mentality simply as a time commitment, not as a measure of our level of care.

Dr. Jain believes this technology has arrived and appears to be safe. Dr. Fritz says no, not yet, for several reasons.

The stiff-upper-lip approach to dealing with medical errors doesn't help your practice, your patients, or you.

Tempted to tell patients when you've made an error but afraid that too much honesty isn't the best policy? Here's how to do it safely.

Can you recognize this menance? Are you familiar with the differences between hospital- and community-based MRSA?

Breast masses are common findings during pregnancy and often difficult to accurately diagnose. That difficulty combined with the false sense of security that a negative ultrasound might impart, can occasionally lull a physician into downplaying what may be a very serious condition.

Considering the amount of experimental evidence to show that adequate amounts of endogenous premenopausal estrogen protect a woman from coronary artery disease, there's reason to believe that the hormone should still play an important role in protecting women after menopause.

The possibility that contraceptives are more likely to fail in obese patients is only one reason why you need to take a different tack when counseling them about their most appropriate birth control options. . .

Recently I had the honor to serve as Acting Chair of a Food and Drug Administration (FDA) advisory committee meeting called to provide advice to the Agency on the creation of new guidelines to improve manufacturer-sponsored clinical trials for hormonal contraceptive (HC) agents. . .

I truly believe that "Protocols for High-Risk Pregnancies" has contributed to improving perinatal care.

True precocious puberty differs from premature adrenarche and premature thelarche. Understanding normal sexual development and these common variants will help ob/gyns make the correct diagnosis and appropriate referrals.

No firm relationship exists between folate intake or blood folate levels and breast cancer risk, according to a recent meta-analysis of prospective and case–control studies on the subject, but discrepancy exists in the findings.

It's never too late to quit smoking when it comes to bone density, according to a recent prospective study of postmenopausal women. And it doesn't take long for benefits to begin to accrue.

The answer appears to be "no," according to the results of a recent observational study.

Women who stop taking alendronate after 5 years do not seem to be at any greater risk for fractures than women who continue treatment, but they do seem to experience a moderate decline in bone mineral density (BMD) and a gradual rise in chemical markers associated with fractures.

Call systems for practicing obstetricians vary widely, with many obstetricians being on call for long hours and most lacking recovery periods after being on call, according to the results of a Wisconsin study published in the January issue of the American Journal of Obstetrics & Gynecology.

Repeating bone mineral density (BMD) scans among postmenopausal women reveals little new information that is helpful in predicting fractures, according to a report in the Jan. 22 issue of the Archives of Internal Medicine.

Children who had nuchal translucency thickening during the first trimester, but a normal karyotype and no structural abnormalities, are clinically and developmentally normal during the first 2 years of life, according to a study in the January issue of the American Journal of Obstetrics & Gynecology.
