Coronary artery disease (CAD) is the number 1 cause of death and disability in the Western world. The incidence of CAD increases with age, although, on average, women present with symptomatic CAD about 10 years later than men. The belief that hormone replacement therapy (HRT) may reduce the incidence of CAD is based on its favorable effects on (1) vasoreactivity, (2) progression of atherosclerosis, (3) lipids and lipoproteins, (4) hemostasis, and (5) impaired glucose tolerance. However, unopposed estrogen may be related to an increased risk of endometrial cancer. The belief that HRT has an overall beneficial effect on cardiovascular disease comes from the results of prospective cohort studies. The Heart and Estrogen/progestin Replacement Study (HERS), however, showed no beneficial effect of HRT on cardiovascular morbidity and mortality. Uncertainty exists about the duration and optimal type of HRT regimen to use, because different estrogens and progestins have yielded different results. Results of ongoing trials addressing similar questions will be published in future years. The Women's Hormone Intervention Secondary Prevention (WHISP) pilot study, using a different HRT regimen from that used in HERS, will assess the effect of HRT on lipid and hemostatic risk markers of heart disease, and it may provide the rationale for a large trial evaluating the effect of HRT on morbidity and mortality.

Some scientists have shown that the oral contraceptive pill can cause breast cancer and heart disease. But no one is really quite sure about the negative side effects of the pill. Experts are sure that the pill can even prevent some forms of cancer. Studies have shown that users will be more protected from cancer of the ovaries than women who do not take the pill. And the protection lasts even after one stops taking the pill. Through the chemical hormones estrogen and progestogen, the pill sends a message to the ovaries not to produce an egg. When a woman is on the pill, her ovaries get a rest. For that reason, there is less chance for problems like cancer to develop. Also, a woman who takes the pill will be more protected from cancer of the endometrium, because the pill causes her to have lighter periods. In addition, with lighter periods, she will probably have less painful periods, too. Taking the pill also will decrease the risk for getting ovary and breast cysts. Pill users have less chance of developing pelvic inflammatory disease (PID), which, if left untreated, can cause damage to the reproductive organs. The best way to ease any concerns about taking the pill is to talk with health care providers about all the issues of birth control pills and other contraception.

A consensus development conference held at the National Institutes of Health on September 13-14, 1979 addressed the issue of estrogen treatment for postmenopausal women. Conference participants included research scientists, physicians, and consumers. Conclusions reached by the conference participants were: 1) estrogens are more effective than placebos in reducing vasomotor symptoms associated with menopause; 2) therapy should be undertaken only if the patient considers the symptoms to be severe enough to warrant treatment, and the smallest dose possible should be administered; 3) estrogens are effective in treating atrophy of the vaginal epithelium, but the use of estrogen creams to treat localized vaginal areas needs further study; 4) estrogens should not be used to treat primary psychological problems; 5) insufficient data is available for determining whether estrogen therapy decreases the risk of fracture associated with osteoporosis; 6) recent investigations indicate estrogen therapy reduces bone loss, but it is not known if the effect is permanant; 7) estrogen therapy appears to neither increase nor decrease the risk of thromboembolism, stroke, or heart disease; 8) estrogen therapy is associated with an increased risk of endometrial cancer but primarily with low grade endometrial cancers; 9) cystic hyperplasia is associated with unopposed estrogen therapy; 10) yearly endometrial samples should be obtained and checked for endometrial changes for all patients receiving estrogen therapy; 11) evidence supporting an association between estrogen therapy and breast cancer is indecisive; and 12) estrogen therapy is associated with an increased risk of gallbladder disease. In general, many areas need further study and patients themselves will have to assess whether symptom relief is of sufficent importance to them to warrant the acceptance of the possible risks involved in the therapy.

Modern medicine 1st made the oral contraceptive (OC), a combined OC, available to women in 1960, and much progress in improving OCs and reducing risks associated with them has occurred. Approximately 200 million women have used OCs worldwide and about 60 million women are currently using this contraceptive method. OCs are efficacious because the hormones in the OCs alter the physiology of the hypothalamo-pituitary-ovarian/uterine axis at 6 sites, e.g., altering the endometrium so implantation of the blastocyst cannot occur. Despite the effectiveness of OCs (virtually 100% effective) in comparison with other contraceptive methods, they often cause side effects and complications. Some side effects and complications from estrogen and predominantly estrogen OCs include vomiting, hypertension, and venous thrombosis/pulmonary embolism. Possible progestogen and predominatly progestogen OC side effects and complications are leucorrhea, urinary tract infections, epilepsy aggravation, and cholestatic jaundice. In addition, pregnancy, venous thromboembolism, heart disease, and malignancies of the breast and genital tract are absolute contraindications to OCs. On the other hand, OCs provide health benefits, in addition to preventing unwanted pregnancies, such as lowered incidence of pelvic inflammatory disease, acne improvement, and protection against endometrial carcinoma and ovarian epithelial neoplasia. In order to ensure that health benefits of OCs are maximized and the risks minimized, family planning practitioners worldwide must monitor OC users for side effects. Recent OC formulations now include the progestogen only OCs, multiphase OCs, low dose OC called gestodene, and the "morning after pill".

At perimenopausal stage, women start losing their bone mineral density. The bone loss results from accelerated bone absorption due to lower estrogen level which often caused climacteric disorders. Then it is possible to treat both osteoporosis and climacteric disorders with estrogen replacement therapy. However, it is necessary that we properly explain the hormone-related disorders (breast cancer, endometrial cancer and heart disease) and get the informed consent at beginning of this therapy.

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility in United States, affecting 6-10% of females in the reproductive age group. Recent studies have shown that insulin resistance plays an important role in the pathogenesis of PCOS. Traditionally, management of PCOS consisted mainly of ovulation induction, treatment of acne and hirsutism, and prevention of endometrial cancer. However, with mounting evidence showing that PCOS is associated with dysmetabolic syndrome and an increased risk for developing diabetes and heart disease, this can no longer be our sole focus. Current data support a strong recommendation that women with PCOS should undergo comprehensive evaluation for diabetes and recognized cardiovascular risk factors and receive appropriate treatment as needed. Lifestyle modifications remain the first-line therapy for all obese women with PCOS. However, many obese women with PCOS find weight loss difficult to achieve and maintain, and this is not an option for lean women with PCOS. For these reasons, insulin-sensitizing drugs are proving to be a promising and unique therapeutic option for chronic treatment of PCOS.

Polycystic ovary syndrome (PCOS) is the common endocrine disorder of reproductive age women which is characterized by hyperandrogenism, chronic anovulation, and increased risk for infertility, endometrial cancer, developing metabolic dysfunction (type II diabetes, dyslipidemia), hypertension and heart disease. The syndrome is also associated with some skin disorders: hirsutismus, alopecia androgenetica and acne. The successful dermatologic therapy requires the holistic diagnosis of the women with skin disorders described above and use the antiandrogenic treatment with conventional methods and laser depilation in hirsutismus. In this paper we present literature studies and our own experiences.

The PTEN hamartoma tumor syndrome, manifestations of which include Cowden disease and Bannayan-Riley-Ruvalcaba syndrome, is caused by various mutations of the PTEN gene located at 10q23. Its major criteria are macrocephaly and a propensity to develop breast and thyroid cancers as well as endometrial carcinoma. Minor diagnostic criteria include hamartomatous intestinal polyps, lipomas, fibrocystic disease of the breasts, and fibromas. Mutations of PTEN can also be found in patients with Lhermitte-Duclos disease (dysplastic gangliocytoma of the cerebellum). The authors report the case of a 17-year-old girl who had a severe cyanotic cardiac malformation for which surgery was not advised and a heterozygous missense mutation (c.406T>C) in exon 5 of PTEN resulting in the substitution of cysteine for arginine (p.Cysl36Arg) in the protein, which was also found in her mother and sister. The patient presented in the pediatric emergency department with severe spastic paraparesis. A magnetic resonance imaging study of the spine showed vertebral hemangiomas at multiple levels, but stenosis and compression were maximal at level T5-6. An emergency T5-6 laminectomy was performed. The decompression was extremely hemorrhagic because the rapid onset of paraparesis necessitated prompt treatment, and there was no time to perform preoperative embolization. The patient's postoperative course was uneventful with gradual recovery. This represents the first report of an association of a PTEN mutation and multiple vertebral angiomas. The authors did not treat the remaining angiomas because surgical treatment was contraindicated without previous embolization, which in itself would present considerable risk in this patient with congenital cyanotic heart disease.

The polycystic ovary syndrome (PCOS), then called the Stein-Leventhal syndrome, was first described in 1935. Originally, diagnosis required pathognomonic ovarian findings and the clinical triad of hirsutism, amenorrhea, and obesity. During fertility years, women with PCOS are often seen for immediate concerns such as infertility, menstrual irregularity, and symptoms of androgen excess. During the past two decades, however, such patients have been observed to have increased risk of cardiovascular disease, dyslipidaemia, hypertension and diabetes and increased risk for endometrial cancer. The management of polycystic ovary syndrome is now complex and includes life style modifications, dietary-induced weight loss, oral contraceptives, clomiphene citrate, gonadotropins, antiandrogens and insulin-sensitising agents. These observations have led to a unique clinical perspective about PCOS--one that recognizes the need to address the immediate issues of irregular bleeding, hirsutism, and infertility, but also emphasizes the long-term goals of preventing diabetes, heart disease, and cancer.

Chronic inflammation may play an etiologic role in endometrial cancer. Nonsteroidal anti-inflammatory drugs (NSAIDs) reduce inflammatory activity by inhibiting the proinflammatory cyclooxygenase enzymes and, therefore, may decrease cancer risk. However, few studies have examined the association between NSAID use and endometrial cancer. We conducted a prospective study among 72,524 women in the NIH-AARP Diet and Health Study. Women completed a questionnaire in 1996-1997 on lifestyle and health-related factors, including type and frequency of NSAID use within the past year, and were followed through 2003 by linkages to cancer registries and vital status databases. During 488,261 person-years of follow-up, there were 732 incident endometrial cancers. NSAID use, compared with nonuse of NSAIDs, was not significantly associated with endometrial cancer risk [relative risk (RR), 0.90; 95% confidence interval (95% CI), 0.74-1.09]. Null associations were also observed by type of NSAID use [aspirin only: RR, 0.88; 95% CI, 0.70-1.11; nonaspirin NSAID (NA-NSAID) only: RR, 1.01; 95% CI, 0.79-1.29; both aspirin and NA-NSAIDs: RR, 0.85; 95% CI, 0.68-1.06]. Generally, results were not statistically significant by frequency of use for aspirin or NA-NSAIDs. Results did not change when women with a history of heart disease, hypertension, or diabetes were excluded to minimize the potential for confounding by indication. Overall, our data do not support an association between aspirin or NA-NSAID use and endometrial cancer risk.
