After exploring the possible mechanism of action of oral contraceptives through an estrogen progestin combination, as well as by means of the sequential method, the pathophysiologic and side effects of the pill, as it appears in the literature, is explored in depth. Thromboembolitic disease is the only condition in which there is a definite association with the use of oral contraceptive pill, and there is some doubt as to how strong the association really is. Some studies suggest that mortality from thromboembolic disorders which can be attributed to the pill is about 3/100,000 per year. Studies have also shown that mortality trends from thromboembolitic disease among women of childbearing ages were parallel to the increased use of oral contraceptives among this group of women, however the data may be weak. Data from various sources indicate that the estrogenic component of the pill are primarily responsible for the thrombogenic effect, with estrogen increasing platelet adhesiveness and enhancing coagulability. Progestogens, on the other hand, enhance fibroinolysis and do not alter platelet function or coagulation. Other side effects of the pill such as naseau, headaches, and weight gain are usually not of any serious consequence. According to 1 study, amenorrhea after cessation of the pill has occurred in very small numbers, but 98% of the women are ovulatory within 3 months after cessation of the pill. The oral contraceptive pill may actually have beneficial effects on genital and endometrial cancer due to the pill's progesterone content. Estrogens have shown both a positive and negative influence on cancer of the uterus and breast, depending on the menopausal status of the women. It is generally agreed that the best dosage of hormones in the pill is the lowest possible varying with the size and body weight of the woman, among other factors. Some studies have shown that in Puerto Rico, IUD users have a higher continuation rate than characteristics than the pill users, thereby making the 2 groups incomparable.

A 38-year-old woman complained of headache, visual impairment, and diabetes insipidus for 18 months prior to rapid onset of Cushing syndrome and amenorrhea. An autopsy disclosed a pituitary carchinoma invading the right cavernous sinus and two liver metastases. The tumor cells were chromophobic and agranular, with scarce polymorphism and rare mitoses. A review of the literature showed that the association of Cushing syndrome to pituitary carcinomas increases in direct proportion to the occurence of metastases. Such association was noted in almost half of the reported cases of pituitary carcinomas with extracranial dissemination.

Pregnon is a new low-dosage ovulation-inhibiting agent containing 1 mg of lynestrenol and .05 mg of ethinyl estradiol in each tablet. It is also marketed under the name of Pregnon 28 or Ovostat 28 in which each package contains 22 active plus 6 placebo tablets. Data were collected from Belgian clinics and evaluated by the Medical Unit of Organon in Belgium and the Netherlands. During this study, 639 women of fertile age were monitored through 9159 cycles. The maximum period of treatment was 36 cycles. Clinical and gynecological examinations were made before treatment and then every 2 or 3 months. Treatment was begun by taking the 1st tablet on the 1st day of menstruation. After taking 22 tablets there was a 6-day tablet-free interval during which withdrawal bleeding usually occurred. The intensity of the withdrawal bleeding was normal in 57.3%, slight in 41.7%, and heavy in 1%. Spotting was noted in 3.1% of the cycles and breakthrough bleeding occurred in 2.9%. Usually they occurred in the first 3 cycles. Amenorrhea was observed in 2.9% of the cycles. Body weights were relatively unchanged. Blood pressures remained the same. Side effects were headache, nausea, vomiting, breast tenderness, heavy legs, leucorrhea, nervousness, depression, and decreased libido. Only 46 patients discontinued treatment because of these drug effects yielding an acceptability level of about 93%. Since no pregnancies occurred during this study, the Pearl index was 0.

36 original cases, 24 from the Hopital de Sainte-Anne in Paris and 12 from the surrounding region, of ischemic (30) or hemorrhagic (6) strokes in women taking oral contraceptives are reported. The patients were 20-55 years, half under 30; took various types of pills from 10 weeks to 10 years, mean 28 months; 30 of them for contraception but other for migraine, Reclus disease, amenorrhea, sterility, and endometri osis. 27 women had related history: ischemic vascular accident (5), hyp ertension (5), thromboembolism (4), Basedow disease (3), heavy smoking (3), essential comitiality (2), migraine (1), essential hyperlipidemia (1). The women with ischemic strokes were younger, 61% under 30. A 3rd had premonitory symptoms like headache, progressing rapidly to massive hemiplegia in 17, discrete hemiplegia in 11, loss of consciousness in 6, and convulsions in 3. The cerebrospinal fluid was clear in 11 cases tested. Angiography revealed lesions in the internal carotid in 4, sylvian arteries in 9, posterior cerebral in 1, but no anomaly in 8. Only 5 recovered completely: 3 died and 7 retained major neurologic dysfunction. 6 women had hemorrhagic strokes, 2 intracerebral hematomas, and 4 cerebromeningeal hemorrhages. 5 were operated on, 3 with good results and 2 were left with severe neurologic sequelae. The authors insisted that none of these women had been given any preliminary tests or followed with any attention to their related history while taki ng oral contraceptives.

This study reports a case of allergy to ergot-derived drugs in a patient with a prolactin (PRL)-secreting microadenoma. The anamnesis revealed allergic reactions to the administration of analgesics and antibiotics. The administration of dopamine agonist drugs, such as bromocriptine (BRC; 2.5 mg) or lisuride (0.2 mg), induced after a few minutes the appearance of nausea, vomiting, postural hypotension, headache, edema of the glottis with dispnea and acroedema. The edemas disappeared a few hours after the administration of antihistaminic drugs while nausea, vomiting, postural hypotension and headache persisted for a few days. Therefore, the patient was tested with another dopamine agonist non-ergot-derived drug, quinagolide (CV 205-502), which did not cause side effects or allergic reactions. Furthermore, not only was the responsiveness to the drug optimal but it also normalized the PRL levels, and menses reappeared after more than a 5-year amenorrhea. This report suggests that ergot-derived drugs, such as lisuride and BRC, seldom induce allergic reactions apart from common side effects. Consequently, the feasibility of using a new drug with a different molecular structure (non-ergot derived) effective in the therapy of hyperprolactinemic syndromes represents a good alternative to conventional therapy.

In addition to oral contraceptives (OCs), the morning-after pill, the minipill, and depot preparations also belong to hormonal contraceptives. The latter two contraceptives have not become established among young women because of inadequate cycle control. For postcoital contraception in Austria, Neogynon and Stediril-D, consisting of 0.05 mg of ethinyl estradiol (EE) + 0.25 mg of levonorgestrel, are used within 48 hours of unprotected intercourse. Lower dose OCs have considerably reduced the risks of side effects. Micropills are the optimal OCs with EE under 50 mcg combined with the new generation of gestagens. The beneficial effects include menstrual regularity and the prevention of anemia, ovarian cysts, and fibrocystic mastopathy. Nausea, headache, spotting, and weight gain do occur in individual cases, even among young people. The potential risk of thromboembolism is the most important, although arterial cardiovascular risk is minimal in young age. The probability of postpill amenorrhea is less than 1%. Micropills can be used by young diabetics provided the disease is not beyond 10 years' duration and there is no angiopathy. Acne, seborrhea, and hirsutism are beneficially influenced by a combination of 0.035 mg of EE with 2 mg of cyproterone acetate. The relative risk of endometrial and ovarian cancer are only about half as high among OC users as among nonusers. The risk of breast cancer in young OC users has not been conclusively explained. Regular colposcopy and cytology is recommended for young OC users to preclude the risk of malignancies of the genital tract. Sex education and the use of OCs that are the most suitable and effective for young people can reduce the number of unwanted pregnancies and abortion. The comparison of two 5-year periods in the 1970s and 1980s at the University Obstetrical-Gynecological Clinic in Graz showed that the incidence of births among women under 18 years of age decreased from 3.6% (778) to 1.6% (353).

The Royal Army Medical Corps (RAMC) of the UK is considering offering women in the Army the option of inducing amenorrhea especially those in war. Logistics problems of supplying sufficient sanitary protection makes inducing amenorrhea in these women an advantage. It is important that the Royal Army not force servicewomen ready for war to agree to chemical induction of amenorrhea, however. A survey of civilian women shows that 80% liked the notion of eliminating menstruation. continuous combined oral contraceptive (COC) therapy induces amenorrhea, but it poses some side effects including bleeding and spotting, 2 kg weight gain, breast tenderness, depression, and headaches. 12 weeks of COC therapy costs range form 2 to 6 pounds. The synthetic androgen used to treat endometriosis, danazol, may also induce amenorrhea at daily doses of 800 mg. It causes various side effects including reduced breast size, flushing, sweating, loss of libido, acne, weight gain, edema, hirsutism, and voice change. 12-week danazol therapy costs about 200 pounds. Another drug with androgenic, antigonadotrophic, antiestrogenic, and antiprogestogenic properties which is also used to treat endometriosis, gestrinone, in another possible amenorrhea inducer at 2 doses of 2.5-5 mg/week. Side effects are similar to those of danazol. In 1 study, all 20 patients developed acne and seborrhea. Its 12 week costs are considerably more than danazol and COC therapy (450 pounds). Intermittent administration of 2 gonadotropin releasing hormone (GnRH) analogues, buserelin and goserelin, suppresses production of gonadotropins. Health workers need to inject 3.6 mg goserelin every 28 days while they administer buserelin subcutaneously or intranasally. the leading side effect on both GnRH analogues is not flushes. 12-week therapy is about 375 pounds. Fertility is restored after discontinuation of all the aforementioned therapies. The GnRH analogue goserelin is the most effective therapy, but the cost factor causes the Royal Army to favor COCs.

During the past decade, the development of various gonadotrophin-releasing hormone (Gn-RH) agonists, which induce reversible hypo-oestrogenism has opened a new area in the medical management of endometriosis. In an open, multicentre phase III study, the efficacy, tolerance and safety of the Gn-RH agonist leuprorelin acetate were tested. The preliminary results of 104 women treated in seven German centres are presented. Pelvic endometriosis was diagnosed by laparoscopy and classified according to the American Fertility Society scoring system: 33% of patients had minimal, 22% mild, 28% moderate and 8% severe endometriosis and in 9% no pathological results were obtained. The patients' mean age was 30 +/- 6 years and 66 had infertility problems. Treatment was started within the first 3 days of the menstrual cycle and consisted of a subcutaneous injection of leuprorelin acetate 3.75 mg, repeated once monthly over 24 weeks. A follow-up period of 12 months after the last injection has been completed in 70 patients, including a second laparoscopy. At all visits, symptoms were evaluated, physical examinations performed, and blood samples collected for haematological screening, serum chemistry determinations and measurement of the gonadotrophins oestradiol and progesterone and leuprorelin acetate. The median score at laparoscopy fell from 12 before operation to 8 after operation and 2 after treatment with leuprorelin acetate. Of the total number of patients, 89% had improvements in their endometriosis, 8% a deterioration and 3% no change. Patients reported improvement in the following: dysmenorrhoea 93%, dyspareunia 62% and pelvic pain 70%. However, all women complained of at least one of the following symptoms: hot flushes 86%, sleep disturbance 62%, sweating 61%, headache 41%, nausea 32% and depression 20%. Fifty-five percent of patients reported additional side effects such as vaginal dryness, fatigue and lower abdominal pain. After the third injection, amenorrhoea persisted in 94% of the women. Four weeks after the first leuprorelin acetate injection median concentrations of oestradiol fell from 45 pg/ml to 11 pg/ml, follicle-stimulating hormone from 7 U/L to 3 U/L and luteinising hormone from 5 U/L to 1 U/L and remained almost unchanged over the observation period. During the 6 months' treatment, laboratory parameters showed no significant deviations from normal; only total cholesterol, high-density lipoprotein cholesterol and alkaline phosphatase increased. Treatment results were judged as good and satisfactory in 82% and 11% of cases, respectively. On the basis of this study, it can be concluded that leuprorelin acetate treatment is safe, well tolerated and effective in the medical management of endometriosis and endometriosis-related complaints.

The efficacy and tolerability of a new oral contraceptive, norgestimate/ethinyl estradiol (250 micrograms of norgestimate/35 micrograms of ethinyl estradiol; Cilag GmbH Research, Sulzbach, Germany) were examined in an open-label study of 59,701 women who were evaluated during 342,348 menstrual cycles; 42,022 women completed the planned treatment regimen of six cycles. A use-efficacy (overall) Pearl index of 0.25 pregnancies per 100 woman-years was calculated based on 342,348 cycles. Tolerability was assessed for all women who completed six treatment cycles. Reductions in mean cycle length and duration of bleeding were noted; 32% of the women experienced reductions in the intensity of bleeding by the end of cycle 6. After six cycles of use, amenorrhea occurred in 1%, spotting in 4%, and breakthrough bleeding in 3% of the participating women. Treatment with norgestimate/ethinyl estradiol had minimal effects on weight, blood pressure, pulse, lipid metabolism, and blood glucose. Adverse effects (acne, nausea, or headaches) occurred at low frequencies and in many cases, were reduced compared with pretreatment levels. The results of this large-scale open trial were comparable with results from two other multicenter trials of the same formulation.

A total of 110 nonmenopausal women (mean age 42.1 years) presenting with symptomatic uterine leiomyomata and/or fibromatous uteri have been enrolled in this trial to evaluate the efficacy of the depot formulation of leuprorelin acetate in decreasing uterine volume and minimizing menorrhagia, dysmenorrhoea and pressure over the bladder. All patients were treated with an intramuscular injection of leuprorelin acetate depot 3.75 mg every 4 weeks for 16 weeks. Clinical examinations and hormonal and ultrasound determinations were performed before, during and at the end of treatment. Appropriate follow-up is still ongoing for most patients. At the end of the treatment period, of 88 women with enlarged fibromatous uteri, 33 (37.5%) showed a decrease in uterine volume of greater than or equal to 50% of the original size, while nine (10.2%) remained with unchanged uterine volume. Of 80 fibromas measurable separately, 47 (52.8%) decreased by greater than 50% of the initial volume and 16 (18%) remained unchanged or even increased. During treatment, clinically advantageous effects were observed in the associated symptomatology, mainly in the production of amenorrhoea and restoration of normal haemoglobin levels. Most of the patients were affected by irregular menstrual blood loss with consequent anaemia that in 29 patients was expressed by low levels of haemoglobin (mean 9.2 g/dl; SD 1.5; range 4.5-11.8 g/dl). By the end of the treatment, only one patient still had moderate vaginal blood loss. Haemoglobin levels rose to a mean value of 11.8 g/dl (SD 1.3; range 8.5-14.1 g/dl). Three patients (2.7%) failed to complete the 16-week treatment protocol, because of headache (one patient) and increased blood pressure (two patients). As a result of the treatment, of the 107 patients who were candidates for surgery and who were included in this study, only nine (8.4%) required surgery during leuprorelin acetate treatment. Of these, four operations were vaginal excision of the submucous myomata protruding into the cervix during treatment, and in five hysterectomy performed because of persistence of symptoms. In most patients the achievement of amenorrhoea minimized the fear of surgical emergency, facilitating an increased awareness of their clinical condition. With the exception of the three patients who dropped out, side effects were mild in all patients, consisting mainly of hot flushes, which were easily tolerated. In the following 8-12 months, the regrowth of uterine volume to original size has been usual in most of the 82 patients now in follow-up.(ABSTRACT TRUNCATED AT 400 WORDS)
