Osteoporosis and the resulting fractures are major public health issues as the world population is ageing. Various therapies such as bisphosphonates, strontium ranelate and more recently denosumab are available. This clinical guide provides the evidence for the clinical use of selective estrogen modulators (SERMs) in the management of osteoporosis in postmenopausal women. © 2011 Elsevier Ireland Ltd.

Introduction: Venous thromboembolism (VTE), including deep venous thrombosis (DVT) and pulmonary embolism (PE), is a serious cardiovascular event whose incidence rises with increasing age. Aims: To formulate a position statement on the management of the menopause in women with a personal or family history of VTE. Material and methods: Literature review and consensus of expert opinion. Results and conclusions: Randomized controlled trials have shown an increased risk of VTE in oral hormone therapy (HT) users. There are no randomized trial data on the effect of transdermal estrogen on VTE. Recent observational studies and meta-analyses suggest that transdermal estrogen does not increase VTE risk. These clinical observations are supported by experimental data showing that transdermal estrogen has a minimal effect on hepatic metabolism of hemostatic proteins as the portal circulation is bypassed. A personal or family history of VTE, especially in individuals with a prothrombotic mutation, is a strong contraindication to oral HT but transdermal estrogen can be considered after careful individual evaluation of the benefits and risks. Transdermal estrogen should be also the first choice in overweight/obese women requiring HT. Observational studies suggest that micronized progesterone and dydrogesterone might have a better risk profile than other progestins with regard to VTE risk. Although these findings should be confirmed by randomized clinical trials, they strongly suggest that both the route of estrogen administration and the type of progestin may be important determinants of the overall benefit-risk profile of HT. © 2011 Elsevier Ireland Ltd.

Introduction: Premature ovarian failure (also known as premature menopause) is defined as menopause before the age of 40. It can be "natural" or "iatrogenic" such as after bilateral oophorectomy. It may be either primary or secondary. In the majority of cases of primary POF the cause is unknown. Chromosome abnormalities (especially X chromosome), follicle-stimulating hormone receptor gene polymorphisms, inhibin B mutations, enzyme deficiencies and autoimmune disease may be involved. Secondary POF is becoming more important as survival after treatment of malignancy through surgery, radiotherapy and chemotherapy continues to improve. Aim: To formulate a position statement on the management of premature ovarian failure. Materials and methods: Literature review and consensus of expert opinion. Results and conclusions: Diagnosis should be confirmed with an elevated FSH greater than 40 IU/L and an estradiol level below 50 pmol/L in the absence of bilateral oophorectomy. Further assessment should include thyroid function tests, autoimmune screen for polyendocrinopathy, karyotype (less than 30 years of age) and bone mineral density. Untreated early ovarian failure increases the risk of osteoporosis, cardiovascular disease, dementia, cognitive decline and Parkinsonism. The mainstay of treatment is hormone therapy which needs to be continued until the average age of the natural menopause. With regard to fertility, while spontaneous ovulation may occur the best chance of achieving pregnancy is through donor oocyte in vitro fertilization. It is essential that women are provided with adequate information as they may find it a difficult diagnosis to accept. It is recommended that women with POF are seen in a specialist unit able to deal with their multiple needs. © 2010 Elsevier Ireland Ltd. All rights reserved.

Introduction: There is emerging evidence on the widespread tissue effects of vitamin D. Aims: To formulate a position statement on the role of vitamin D in postmenopausal women. Materials and methods: Literature review and consensus of expert opinion. Results and conclusions: Epidemiological and prospective studies have related vitamin D deficiency with not only osteoporosis but also cardiovascular disease, diabetes, cancer, infections and neurodegenerative disease. However the evidence is robust for skeletal but not nonskeletal outcomes where data from large prospective studies are lacking. The major natural source of vitamin D is cutaneous synthesis through exposure to sunlight with a small amount from the diet in animal-based foods such as fatty fish, eggs and milk. Vitamin D status is determined by measuring serum 25-hydroxyvitamin D [25(OH)D] levels. Optimal serum 25(OH)D levels are in the region of 30-90 ng/mL (75-225 nmol/L) though there is no international consensus. Levels vary according to time of the year (lower in the winter), latitude, altitude, air pollution, skin pigmentation, use of sunscreens and clothing coverage. Risk factors for low serum 25(OH)D levels include: obesity, malabsorption syndromes, medication use (e.g. anticonvulsants, antiretrovirals), skin aging, low sun exposure and those in residential care. Fortified foods do not necessarily provide sufficient amounts of vitamin D. Regular sunlight exposure (without sunscreens) for 15 min, 3-4 times a week, in the middle of the day in summer generate healthy levels. The recommended daily allowance is 600 IU/day increasing to 800 IU/day in those aged 71 years and older. Supplementation can be undertaken with either vitamin D2 (ergocalciferol) or vitamin D3 (cholecalciferol) with monitoring depending on the dose used and the presence of concomitant medical conditions such as renal disease. © 2011 Elsevier Ireland Ltd.
