The symptoms can begin in the early, mid or late luteal phase and are not associated with defined concentrations of any specific gonadal or non-gonadal hormone. Although evidence for a hormonal abnormality has not been established, the symptoms of the premenstrual disorders are related to the production of progesterone by the ovary. The two best-studied and relevant neurotransmitter systems implicated in the genesis of the symptoms are the GABArgic and the serotonergic systems. Metabolites of progesterone formed by the corpus luteum of the ovary and in the brain bind to a neurosteroid-binding site on the membrane of the gamma-aminobutyric acid (GABA) receptor, changing its configuration, rendering it resistant to further activation and finally decreasing central GABA-mediated inhibition. By a similar mechanism, the progestogens in some hormonal contraceptives are also thought to adversely affect the GABAergic system. The lowering of serotonin can give rise to PMS-like symptoms and serotonergic functioning seems to be deficient by some methods of estimating serotonergic activity in the brain; agents that augment serotonin are efficacious and are as effective even if administered only in the luteal phase. However, similar to the affective disorders, PMS is ultimately not likely to be related to the dysregulation of individual neurotransmitters. Brain imaging studies have begun to shed light on the complex brain circuitry underlying affect and behaviour and may help to explicate the intricate neurophysiological foundation of the syndrome.

The method involved review of the pertinent published literature. Premenstrual disorders vary in prevalence according to the definition or categorization. The most severe disorder being premenstrual dysphoric disorder (PMDD) affects 3-8% of women of reproductive age. This disorder focuses on psychological symptoms whereas global studies show that the most prevalent premenstrual symptoms are physical. Both psychological and physical symptoms affect women's activities of daily life. A considerable burden of illness has been shown to be associated with moderate to severe premenstrual disorders. In conclusion, premenstrual symptoms are a frequent source of concern to women during their reproductive lives and moderate to severe symptoms impact on their quality of lives.

Although pre...Premenstrual disorders have been recognized as affecting innumerable women for decades but unlike most other medical conditions universally accepted criteria for definition and diagnosis are not established. Although premenstrual syndrome (PMS) occurs throughout reproductive life, there are some women who become particularly troubled. Those approaching the menopause may also have a mixture of PMS and menopause symptoms, not to mention heavy periods. Furthermore, some of the symptoms are similar in nature and so it is a challenge to identify which set of symptoms belongs to which spectrum. This is an area that has not been explored well. Various classifications have been proposed over the last few decades. A further effort towards the classification was made by an international multidisciplinary group of experts established as the International Society for Premenstrual Disorders (ISPMD) in Montreal in September 2008. Their deliberations resulted in a unified diagnosis, classification of premenstrual disorders (PMD) along with their quantification and guidelines on clinical trial design. This classification of PMS is far more comprehensive and inclusive than previous attempts. PMD in the ISPMD Montreal consensus are divided into two categories: Core and Variant PMD. Core PMD are typical, pure or reference disorders associated with spontaneous ovulatory menstrual cycles while Variant PMD exist where more complex features are present. Further, the consensus group considered that PMD may be subdivided into three subgroups predominantly physical, predominantly psychological and mixed. Variant PMD encompass primarily four different types; premenstrual exacerbation, PMD with anovulatory ovarian activity, PMD with absent menstruation and progestogen-induced PMD.

Neverthel...Despite a re-evaluation of risks in recent years, hormone replacement therapy is still surrounded by controversy. Almost 30% of women in a recent survey sought a natural approach to combat climacteric symptoms. Nevertheless, a large proportion of patients felt that they wanted a good safety profile and strong evidence base for treatment. This article seeks to review the evidence supporting non-hormonal approaches to treatment. There is only conflicting evidence at best to support alpha-2 agonists, e.g. clonidine and limited evidence for dihydroepiandrosterone and natural progesterones. There is limited randomized controlled trial data for gabapentin, selective norepinephrine re-uptake inhibitors (SNRIs) and selective serotonin re-uptake inhibitors (SSRIs), many of these studies being related to breast cancer patients. Of the herbal medicinal products, the largest evidence base rests with phytoestrogens. A Cochrane Database review looking at all types of phytoestrogens, e.g. red clover extracts, dietary soya and soya extracts concluded that there was no evidence to support improvement in climacteric symptoms and the meta-analysis of a 178 studies on soy products was inconsistent. Nevertheless, other studies disagree. Mammographic density is not affected by soy or phytoestrogen products and recent in vitro work shows only a weakly proliferative effect of soy isoflavone on breast cancer cells and evidence that soy isoflavone blocks the proliferative effect of estradiol on these cells. There are no studies looking at clinical outcome measures for cardiovascular disease but a number of studies looking at biochemical markers including arterial wall stiffness and apolipo protein B. Recent studies have also looked at the effects of red clover isoflavone on mood and depression, using specific depression rating scales. Finally, it is important to note that herbal medicinal products should not be used without caution. Some may produce quite marked side-effects in high doses and others can interact with pre-existing medication. A strategy for which patients are suitable for herbal medicinal products is reviewed.

Individuals with urogenital atrophy have symptoms that include vaginal dryness, vaginal and vulval irritation, vaginal soreness, pain and burning during urination (dysuria), increased vaginal discharge, vaginal odour, vaginal infections, recurrent urinary tract infections, pain associated with sexual activity (dyspareunia) and vaginal bleeding associated with sexual activity. Despite the frequency and effects of vaginal atrophy symptoms, they are often under-reported and, consequently, under-treated. Therefore, care of a menopausal woman should include a physical assessment of vaginal atrophy and a dialogue between the physician and the patient that explores existing symptoms and their effect on vulvovaginal health, sexuality and quality-of-life issues. The development of the ultra-low-dose 10-µg estradiol vaginal tablets is in line with the requirements of regulatory agencies and women's health societies regarding the use of the lowest effective hormonal dose. Because of its effectiveness and safety profiles, in addition to its minimal systemic absorption, the 10-µg estradiol vaginal tablet can offer greater reassurance to health-care providers and postmenopausal women with an annual estradiol administration of only 1.14 mg.

STUDY DESIGN: Cross-sectional study of consecutive women presenting with postmenopausal vaginal bleeding at a gynaecological oncology centre in the UK. Main outcome measures Endometrial cancer diagnosis. RESULTS: Over a 62-month period, 4847 women were investigated for postmenopausal vaginal bleeding. The majority of women (4097, 84.5%) did not use any HRT preparation at the time of initial referral and 750 (15.5%) women were using combined HRT preparations. A total of 298 (6.1%) women were diagnosed with endometrial carcinoma. Women using HRT preparations were significantly less likely to be diagnosed with endometrial cancer compared with women not using HRT (adjusted odds ratio = 0.229, 95% CI 0.116-0.452; P < 0.0001). The longer duration of HRT use did increase the risk of diagnosing endometrial cancer in women presenting with postmenopausal vaginal bleeding, but this was not statistically significant. CONCLUSIONS: Postmenopausal women presenting with vaginal bleeding and using combined HRT preparations have significantly lower risk of being diagnosed with endometrial cancer when compared with women not using HRT.

Yet very little is known about the impact menopause has on the mental health of women especially severe and enduring illnesses like schizophrenia. A lot of research has shown that estrogen acts as a protective factor due to its antidopaminergic properties, thus providing an explanation for the increase in risk of a new psychotic disorder during the menopause. This has further led to the hypothesis of hormone replacement therapy providing benefits in the management of these disorders in menopausal women. This review article highlights the importance of a clear understanding of this phase of life in patients suffering from or who present with a risk of developing schizophrenia.

Signs and symptoms are categorized as physical and psychological changes, including depression, hot flushes and ageing. Woman's responses to menopause are governed by lifestyle factors. The purpose of this study was to determine how Iranian women experience menopause and hormone therapy. A qualitative inquiry was conducted through semistructured, in-depth interviews to explore study questions in 11 menopausal women. Participants had positive and negative menopause experiences. Negative menopause experiences are due to severity of symptoms. Menopause can be facilitated by increasing women's knowledge about this phase and ways to cope with it.

Age, parity and obesity are the most consistently reported risk factors. Many women can be asymptomatic of prolapse but common symptoms include a sensation of a bulge or fullness in the vagina or urinary, bowel or sexual dysfunction. Management depends upon symptoms and the type and grade of the prolapse as well as any associated medical co-morbidities. Management options include expectant, conservative or surgical approaches. Up to 10% of women having a surgical procedure for prolapse will require a second procedure. It is, therefore, important to consider lifestyle modifications such as weight loss and conservative measures including pelvic floor muscle training, topical estrogens and pessaries as initial management options.

This double-blind, randomized study was performed at Huddinge Hospital of Karolinska Institutet, Stockholm in order to test the effectiveness of topical oxytocin gel in women with postmenopausal vaginal atrophy. METHODS: Twenty postmenopausal women (at least two years after menopause) with symptoms of vaginal atrophy such as vaginal dryness, pain, itching, discomfort and bleeding during intercourse were enrolled in the study when visual inspection of the vagina had confirmed that their mucosa was atrophic. The participants were randomized to intravaginal treatment with either oxytocin or placebo gel for seven days. Before and after treatment, a gynaecological examination and a visual and colposcopic inspection of the vagina were performed, biopsies from the vaginal mucosa were taken and blood samples were collected for analysis of circulating levels of estradiol and oxytocin. RESULTS: Prior to treatment, visual and colposcopic inspection showed that all of the 20 participants had an atrophic vaginal mucosa. After treatment with the oxytocin gel, the examination showed that the vaginal epithelium of seven of the 10 participants in the oxytocin group had become healthier and normalized. No change in these parameters was observed among the 10 participants in the placebo group. This difference between the oxytocin and placebo groups was significant (P= 0.003). Seven participants in the active group and four in the placebo group reported relief of symptoms of vaginal atrophy after seven days of applying the gel. The effect of oxytocin to normalize the morphological appearance of the vaginal mucosa was almost significant when compared with the placebo group (P= 0.07). There was no significant difference between the circulating levels of estradiol and oxytocin in both the oxytocin and placebo groups before and after treatment. None of the participants reported any side-effects. CONCLUSION: Topical treatment with oxytocin appears to improve vaginal atrophy in postmenopausal women. A limitation of this pilot study is that it was based on a small study population hence the results should be regarded with caution. Larger studies are in progress to establish the possibility of using oxytocin as a clinical treatment for vaginal atrophy.

This resulted in a big drop in HRT use and its demotion by regulatory authorities to second-line treatment. Many clinicians now feel that HRT is not safe to use, and recommend various alternatives for the treatment of osteoporosis. But how effective are these alternative therapies, are they any safer than HRT, and how do their costs compare? This review questions the validity of the safety concerns about HRT, and highlights the safety concerns about alternative therapies. It concludes that HRT is as safe as the other treatment options, and its efficacy and low cost demand that it be restored as a first-line treatment for the prevention of postmenopausal osteoporosis. Other therapies are available for use in osteoporosis, and the bisphosphonates are particularly effective for the treatment of the established disease. However, they must be used selectively and with caution, and are best restricted to those patients who are elderly or have severe disease. New treatments are emerging, but again caution must be taken until any long-term adverse effects have been identified.

This paper reviews findings from studies investigating the influence of sex hormones in postmenopausal women with and without hormone therapy (HT). Functional brain organization was investigated using different behavioural tasks in postmenopausal women using either estrogen therapy or combined estrogen plus gestagen therapy and age- and IQ-matched postmenopausal women not taking HT. The results revealed HT-related modulations in specific aspects of functional brain organization including functional cerebral asymmetries and interhemispheric interaction. In contrast to younger women during the menstrual cycle, however, it seems that HT, and especially estrogen therapy, after menopause affects intrahemispheric processing rather than interhemispheric interaction. This might be explained by a faster and more pronounced age-related decline in intrahemispheric relative to interhemispheric functioning, which might be associated with higher sensitivity to HT. Taken together, the findings suggest that the female brain retains its plasticity even after reproductive age and remains susceptible to the effects of sex hormones throughout the lifetime, which might help to discover new clinical approaches in the hormonal treatment of neurological and psychiatric disorders.
