The North American Menopause Society (NAMS) 2016 annual meeting mentioned that HRT may have more benefits than risks in women before the age of 60.A consensus expert opinion published by The Endocrine Society stated that when taken during perimenopause or the initial years of menopause, HRT carries fewer risks than previously published, and reduces all cause mortality in most scenarios. The American Association of Clinical Endocrinologists (AACE) has also released position statements approving of HRT when appropriate.Women receiving this treatment are usually post-, peri-, or surgically menopausal. Menopause is the permanent cessation of menstruation resulting from loss of ovarian follicular activity, defined as beginning twelve months after the final natural menstrual cycle. This twelve month time point divides menopause into early and late transition periods known as perimenopause and postmenopause. Premature menopause can occur if the ovaries are surgically removed, as can be done to treat ovarian or uterine cancer. Demographically, the vast majority of data available is in postmenopausal American women with concurrent pre-existing conditions and an average age of over 60 years. Menopausal symptoms
HRT is often given as a short-term relief from menopausal symptoms during perimenopause.
Prevalence of clinical symptoms suggestive of KBD reaches 100% in 5- to 15-year-old children in at least one village. Prevalence rates of over 50% are not uncommon. A clinical prevalence survey carried out in Lhasa prefecture yielded a figure of 11.4% for a study population of approximately 50,000 inhabitants. As in other regions of China, farmers are by far the most affected population group. Eponymy
The condition was named after Russian military physicians Evgeny Vladimirovich Bek (1865–1915) and Nicolai Ivanowich Kashin (1825–1872). Because of varied transliteration from Cyrillic script into the Latin script of both German orthography and English orthography, the disease name has been spelled variously as Kashin–Beck disease, Kashin-Bek disease, and Kaschin-Beck disease. The noneponymous names endemic osteoarthritis, osteoarthritis deformans endemica, and osteoarthritis deformans have also been used. See also
