Estrogen-related cardiovascular dysfunction was noted in 23 out of 30 patients with prostatic cancer (PC). Coronary subjects with PC suffered from cardiac pain evident on ECG necessitating correction by effective doses of coronary active drugs. PC patients with essential hypertension exhibited frequent headache, progressive edema of the legs, drastic hypertensive reactions. It is held that estrogen therapy for prostatic cancer should be preceded and monitored by therapeutic evaluation responsible for optimal conditions to prevent and early diagnose cardiovascular complications.

Health care practitioners are often faced with the dilemma of whether or not to provide oral contraceptives (OCs) to women who have certain chronic medical conditions. Oral contraceptive use among gestational diabetics who use OCs may be at increased risk for developing insulin- dependent diabetes. It appears that progestins are primarily responsible because they decrease the number of insulin receptors on cell membranes. Norgestrel has a more marked effect on carbohydrate metabolism than norethindrone. Estrogen may also play a role by slowing the uptake of glucose. Findings of available studies show that progestin only OCs, combined, low-dose OCs (35 mcg of ethinyl estradiol), or preparations with norethindrone are relatively safe for gestational diabetics. In mitral valve prolapse (MVP) abnormal hemodynamics at the prolapsed valve may promote formation of thrombi and lead to cerebrovascular accidents (CVAs). Oral contraceptives are also known to increase the incidence of thrombi, especially in the lower extremities. A 1986 study of 11 OC users who had had CVAS found that a specific subject of women with MVP are at risk for CVA, perhaps due to persistent clotting abnormalities, however most could safely use a combined, low-dose pill unless headaches, smoking, and MVP symptoms. Oral contraceptive use has usually been avoided in women with sickle cell disease. The major concern has been the possibility of an additive or synergistic effect of OCs on the blood-clotting mechanism. However sickle cell disease is a relative contraindication. Several studies showed that OC use, even up to 54 months, did not increase sickle cell crises, and only 5 cases of thromboses have been reported. The increase of fetal and maternal mortality, however, is a definite risk, therefore a similar low-dose pill may be safe for women with the sickle cell trait.

Mechanism of action, indications, side effects and contraindications of oral contraceptive agents (OCA) are reviewed. OCA can be divided into two groups: consecutive and combined agents. Combined OCA contain both estrogens and gestagens and are taken for 3 weeks, while consecutive OCA contain only estrogens and are taken for 2 weeks followed by 1 week of combined OCA until the onset of menstruation. Biological activity of synthetic gestagens is estimated by a dosage which results in a delay of menstruation by 2 weeks. Gestagens norethindrone and norethynodrel were shown to be equally effective, while ethinodiol diacetate and norgestrel were 15-30 times more effective. Estrogen component of OCA is represented by ethinyl estradiol or mestranol. Combined OCA are more effective than consecutive OCA; probability of undesirable pregnancy during administration of combined OCA does not exceed 0.2%. The most frequent side-effects of OCA include nausea, headache, uterine hemorrhage, and changes in libido. OCA can affect the endocrine and reproductive systems. Major endocrine effects of OCA include changes in the cortisol metabolism in the adrenal glands, increase in the level of thyroid-binding globulin in the thyroid gland, changes in the glucose metabolism in the pancreas, inhibition of the luteinizing hormone releasing hormone in the hypothalamus with simultaneous decrease in the production of pituitary gonadotropins and inhibition of the ovulation. The most serious side-effects of OCA include cholelithiasis, thrombophlebitis, thromboembolism, liver adenoma, and myocardial infarction. Absolute contraindications to the use of OCA include hypertension, hyperlipidemia, breast or endometrial cancer, pregnancy, cardio-vascular diseases, liver diseases, and kidney insufficiency.

Detailed interview information was obtained from 515 women in connection with a Swedish-Norwegian comparative investigation on possible connections between use of oral contraceptives (OCs) and premenopausal breast cancer. The Norwegian data was reviewed to ascertain the occurrence of mild side effects and how these side effects influence the use of OCs. In all, 63% of those interviewed had used OCs. Side effects were reported in 55.6% of the 629 use periods. The most frequent side effects were weight gain (17.8%), irregular menses (14.0%), nausea (8.9%) and tender breasts (8.8%). The respondents also reported depression, aggressiveness, decreased libido, headache and migraine. Differences in side effects were found for various OCs depending upon quantity of hormone and composition. Estrogen related complaints such as tender breasts and weight gain increased in relation to the estrogen dosage in the pill. Users of the minipills often reported irregular menses. Reports of psychological problems were relatively evenly distributed but users of minipills reported significantly lower rates of side effects for such complaints. Although relatively few use periods were reported for triphasic pills, these also appear to be involved with a number of side effects. 2 out of 5 women who began taking OCs reported that they had to stop because of side effects. This reduced the value of OCs as an effective and easily obtainable means of contraception.

Symptoms due to estrogen deficiency begin in the perimenopausal years and progress as serum levels of this hormone decrease Vasomotor instability, manifested by hot flushes or night sweats, may persist for several months to a few years. Psychologic symptoms include anxiety, tension, depression, insomnia, palpitations, and headaches. Atrophy of the genital epithelium may result in senile vaginitis with symptoms of irritation, burning, pruritus, dyspareunia, and even vaginal bleeding. Even the lower urinary tract mucosa is dependent upon estrogen. Postmenopausal osteoporosis affects 25 to 50% of older women and increases the risk for vertebral, hip, and other fractures. Estrogen therapy for menopausal complaints has received adverse publicity because several reports have indicated that unopposed estrogens increase the risk of endometrial cancer. Added progestogen not only negates this risk but reduces the incidence of endometrial adenocarcinoma in estrogen-progestogen users to less than that observed in untreated women. Estrogen replacement therapy does not increase the risk of breast cancer; the incidence of this malignancy, however, was also less in the estrogen-progestogen users when compared with either the untreated women or from that expected from the national cancer surveys. In evaluating postmenopausal women for hormone replacement, the benefits of estrogen-progestogen therapy must be weighed against possible risks.

Diethylstilbestrol (DES) is a nonsteroidal synthetic estrogen. It has been approved as a "morning-after" contraceptive. It is thought to interfere with the implantation of the fertilized ovum. Among 5593 women treated with DES or other estrogens, 26 pregnancies have been reported. Most of these patients reported midcycle exposures. Of 92 patients with adenocarcinoma of the vagina or cervix, prenatal histories of 66 were obtained. The mothers of 49 of them had taken DES or related nonsteroidal estrogens during pregnancy. In 1 case the mother had received only 1.5 mg daily. Another mother was treated for only 5 days during the first trimester. There is no evidence that the use of DES increases the risk of cancer in the mother. The Food and Drug Administration has approved the use of DES as an emergency treatment only. Early therapeutic abortion is recommended when this use of DES fails, because of the possibility of a teratogenic effect. The recommended oral dosage is 25 mg twice daily for 5 consecutive days, begun within 72 hours after sexual exposure. Severe nausea and vomiting may occur. Headaches and menstrual irregularities have also been reported.

An approach to the management of the climacteric and postmenopausal patient is outlined. Menopause refers to the time at which menstruation ceases; climacteric, the period of transition. Neither is pathological. After the functional life of the ovary terminates when the supply of primary oocytes is exhausted, the feedback mechanism with FSH is disrupted leading to high blood and urinary levels of FSH. Estrogen often continues to be produced for about 10 years postmenopausally. Hormone therapy is indicated to treat vasomotor instability, such as hot flashes, numbness and tingling, vertigo, cold hands and feet, palpitations and headache, dysfunctional uterine bleeding, and senile vaginitis. The psychological changes often noted are functional and not due to estrogen withdrawal. There is currently no proof of the efficacy of long term estrogen replacement as a means of preventing heart diseases or osteoporosis.

A worsening of migraine headaches has been associated with estrogens, given for birth control and menopausal syndrome. It is suggested in this case history report that the same may be true in the male migrainous patient, in whom estrogens are rarely used. 1 week following surgery for prostatic carcinoma a 75-year-old white man who was started on stilbestrol 5 mg daily began to experience severe bifrontal, throbbing headaches with nausea and occasional vomiting. The headaches lasted 4-6 hours and appeared 3 or 4 times weekly. Fortification spectra in both visual fields and language disturbances occurred during the headache period. Stilbestrol was discontinued 4 months later, and the headaches improved. After 1 week without headaches, stilbestrol was begun again and similar headaches promptly recurred. Stilbestro was again discontinued, and the headaches immediately improved. 1 month later the patient was free from headache and has since remained so. Between the periods of headache, neurological examination was normal. The patient had a history of moderate common migraine, but following estrogen medication his symptoms became those of a severe clsssic migraine. The case raises the possiblity that the relation between estrogens and migraines is not limited to a fall in estrogen blood levels; steady or rising levels of estrogens possibly produce a similar effect.

Breakthrough bleeding as a side effect of oral contraceptive (OC) use is considered one of the primary causes if discontinuation of oral contraceptives. In this study, the incidence and pattern of vaginal bleeding is examined and correlated with biologic responses and plasma steroid bioavailability. Between October 1, 1985 and October 15, 1987, subjects were randomly selected from eligible women beginning OC use as patients of the Department of Gynecology and Obstetrics at the Johns Hopkins Medical Institutions. Women were grouped by type of OC as follows: 1) 67 women taking 50 micrograms of ethinyl estradiol and 1.0 mg of norethindrone (OC1);l 2) 61 women taking 35 micrograms of ethinyl estradiol and 1.0 mg of norethindrone (OC2); and 3) 64 women taking 35 micrograms of ethinyl estradiol and .5 mg of norethindrone (OC3). Estrogen and progesterone concentrations in plasma were measured on the 21st day during the third, sixth, and ninth cycles. The samples was taken 24 hours after ingestion of the pill for day 20, and 1 hour after taking the pill on day 21. An extensive interview was also conducted for all study participants. Bleeding was recorded for any amount of bleeding occurring during days 2 through 21, and during days 21 through 28. Cycles were omitted where pills had been forgotten by the patient. An initial slope was calculated with the 1 hour value level and subtracting the 0 hour level over the actual time interval. Linear regression analysis was used to compare the slopes and bleeding days. Of the 316 women enrolled, 61% (192) completed the study. The findings were that the incidence of intermenstrual bleeding was not statistically different among the various preparations. For 59 patients eliminated from the study, 24% experienced intermenstrual bleeding. Those lose to follow-up were not among those unwilling to tolerate their bleeding pattern. There was similar incidence of other side effects among all three preparations: .5% amenorrhea of dysmenorrhea, 7% nausea, 16% headache, 26.5% depressed mood, 16.6% breast tenderness, and 44.3% acne. The low-dose OC3 had the statistically highest rates of intermenstrual bleeding. The bleeding patterns are described. Bleeding patterns were higher than those previously reported in the literature. Further research might focus on controlling for factors such as hormone-binding globulin capacity.

The normal female life cycle is associated with a number of hormonal milestones: menarche, pregnancy, contraceptive use, menopause, and the use of replacement sex hormones. All these events and interventions alter the levels and cycling of sex hormones and may cause a change in the prevalence or intensity of headache. The menstrual cycle is the result of a carefully orchestrated sequence of interactions among the hypothalamus, pituitary, ovary, and endometrium, with the sex hormones acting as modulators and effectors at each level. Estrogen and progestins have potent effects on central serotonergic and opioid neurons, modulating both neuronal activity and receptor density. The primary trigger of menstrual migraine appears to be the withdrawal of estrogen rather than the maintenance of sustained high or low estrogen levels. However, changes in the sustained estrogen levels with pregnancy (increased) and menopause (decreased) appear to affect headaches. Headaches that occur with premenstrual syndrome appear to be centrally generated, involving the inherent rhythm of CNS neurons, including perhaps the serotonergic pain-modulating systems.
