[Oral contraceptives--indications and neurological complications (author's transl)].

The influence of oral contraceptive agents on neurologic diseases in not clear. Animal experiments suggest that estrogens lower the seizure threshold whereas gestagens have the opposite effect. In women with epilepsy no change in the pattern of attacks could be observed under oral contraceptives. The inducing effect of hydantions and barbiturates on drug metabolizing enzymes requires the prescription of higher doses of estrogens and gestagens. Otherwise unwanted pregnancy can result, an especially unfavourable event in regard to the teratogenicity of hydantoins and barbiturates and possibly or oral contraceptives, too. An immunosuppressive effect of oral contraceptives - found in animals with EAE--could be favourable in respect to the disturbed immune mechanism of patients with multiple sclerosis and myasthenia. The influence of oral contraceptives on migraine seems to vary. The risk of arterial cerebral thromboembolic disease is increased in women taking oral contraceptives. The correlation to the estrogen content of the drugs remains to be proved.

Virucidal effect of certain chemical contraceptives on Type 2 herpesvirus.

The virucidal effect of several chemical contraceptives was investigated and the findings are rrported. The supension of Type 2 herpes simplex virus, containing 10(6) to 10(7) tissue culture infectious doses per 0.1 ml., was inactivated on exposure to five different chemical contraceptives. For quantitative estimates of virucidal effect, 10 per cent solutions of these chemical contraceptives were tested with an exposure time of 10 minutes at room temperature. The methods for determination of residual infectivity included both virus assays in cultures of Vero cells and human embryo fibroblasts, as well as the intracranial inoculation of mice. Virus infectivity decreased 1,000- to 10,000-fold after contact with chemical contraceptives, indicating a substantial virucidal effect.

Ovarian function after the menarche and hormonal contraception.

The aim of the study was to determine the date of regular ovulation after the menarche to better understand the physiology of female adolescence, especially as it pertains to the use of hormonal contraception. Early morning urine samples were collected from 51 girls in the perimenarche for 9 weeks semi-annually during 2 years. Estrone- and pregnanediol-3-glucuronide values were determined. Cycles lasting 35-40 days at the onset of menses shortened to 28 days after the 23rd-25th cycle. Menses reached a 5.0-5.5 day average length at about the same time. After the 20th cycle, ovulation could be demonstrated in more than 50% of the study patients. Using a scoring system, regular ovulation could be expected on the basis of somatic data with scores of greater than 16. Hormonal contraception may be prescribed 2 years after the menarche, based on scores of greater than 16 and ovulation proven be hormonal cytology and basal body temperature.

Adrenal steroids and the development of osteoporosis in oophorectomised women.

To explore the possibility that the wide variation in bone loss among oophorectomised women might be due to differences in adrenal androgens or their biosynthetic pathways, 18 women (10 with very fast and 8 with very slow bone loss) were selected. Serum levels of nine adrenal steroids, including the major androgens and cortisol, were measured under basal conditions and after overnight suppression followed by acute corticotropin stimulation. In addition, basal serum oestrone, oestradiol, dehydroepiandrosterone sulphate, sex-hormone-binding-globulin, corticosteroid binding globulin, and urinary free cortisol were measured. The only significant differences found were that women who lost bone rapidly had significantly higher urinary free-cortisol excretion (p less than 0.001) and a paradoxically diminished cortisol response to corticotropin. These data make it unlikely that endogenous adrenal androgens or oestrogens are a major factor in preventing bone loss after cessation of ovarian function; cortisol by its catabolic effect, however, may be a significant factor in causing osteoporosis.

The effects of oral contraceptives and parity on ovarian cancer trends in women under 55 years of age.

Mortality from epithelial ovarian cancer is falling in women under 55 years of age in England and Wales. The decline does not appear to be a treatment effect nor to be attributable to changes in the rate of oophorectomy. Case-control studies have shown that high parity and oral contraceptive use are protective against the disease. We suggest that the decrease in mortality is compatible in timing and magnitude with exposure to oral contraceptives. No obvious effect on mortality attributable to parity was apparent in this analysis. Oral contraceptives may prove to be a widely acceptable means of preventing ovarian cancer, providing they do not increase breast cancer risk.

Lipid metabolic studies in women with a polycystic ovary syndrome during treatment with a low-dose desogestrel-ethinylestradiol combination.

Twenty women with the polycystic ovary syndrome (PCO) were treated with a combination of desogestrel and ethinylestradiol (EE) and the effects on lipids and lipoproteins were compared with those induced in a group of 13 regularly menstruating, healthy women. All women were examined before and after 3 months of treatment. Compared with the regularly menstruating women, the PCO women had significantly higher body weights and blood pressure as well as elevated levels of triglycerides in serum and VLDL. During treatment, 14 out of 20 women affected by PCO lost weight. No significant change in blood pressure was observed. In the PCO group, moderate increments were encountered in serum cholesterol, phospholipids and triglycerides. No significant changes were seen in LDL-cholesterol or HDL-cholesterol. The ratio LDL-cholesterol/HDL-cholesterol did not alter. The level of total cholesterol in VLDL rose during treatment. These changes in serum and lipoprotein lipids in PCO patients were of the same type and magnitude as those found in the control group, apart from an increase in HDL-cholesterol in the latter. The only remaining difference after treatment was a slightly higher level of VLDL triglycerides in the PCO women. Thus only moderate changes were induced in lipid and lipoprotein patterns by the combination of desogestrel and EE. A "positive" influence on lipids and lipoproteins cannot be considered as a further advantage, added to the list of indications when hormonal treatment is used in PCO-affected women. The clinical implications of elevated triglycerides remain to be clarified.

Medical aspects of contraception.

It is evident that choice of contraceptive has important medical implications, whether a mechanical or a hormonal method is elected. Each technology has unique benefits and risks, constraints, applicability, and inconvenience. Wise advice in a medical context must be based on thorough familiarity with the options available to each woman.
