[Physiology of the ovary. VI. Anovulatory menstruation].

In 65 patients with menstrual cycle alterations--in it's length and/or amount of bleeding--estradiol-progesterone relationship was studied. The plasma levels of these hormones were correlated with basal temperature, length of menstrual cycle and histologic study of endometrium. The patient- were grouped as follows: I excessive menstrual bleeding; II short menstrual cycles; III long menstrual cycles; IV increment of bleeding period and, V uterine hemorrhage. All patients had an anovulatory menstrual cycle; peripheral concentration of progeseterone was less than 6 ng/ml and mean concentration of estradiol was not statistically higher than that found in normal patients (83+/-23 pg/ml). Based upon these findings, it is postulated that the term of hyperestrogenism or excessive estrogen production should not be used when referring to these menstrual cycle alterations.

[Effect of chlormandinone acetate upon seizures in epileptic children with latent signs of hyperandrogenism].

The effect of chlormadinone acetate (24 mg/day) upon the plasma levels of pituitary gonadotropins and gonadal hormones on the number of generalized convulsions and spike EEG density was investigated in a group of epileptic children with intractable seizures and with clinical signs suggestive of hyperandrogenism. In each case, the effect of chlormadinone was evaluated in relation to hormonal levels and seizures observed during a control period and under the effect of placebo as follows: Control (PC)-Chlormadinone acetate (PCL1)-Placebo (PP)-Chlormadinone acetate (PCL2). In a male child (4MS), the number of convulsive attacks observed in the control period (26/month) was reduced during PCL1 (2/month) increased during PP (12/month) and was reduced again during PCL2 (0/month). Spike EEG density showed a parallel course to the clinical attacks. In this case, control levels of testosterone were markedly elevated (40 ng/ml) and were decreased during PCL1 to 4.0 increased again during PP to 34.0 and decreased again during PCL2 to 1.2 ng/ml. Plasma levels of pituitary gonadotropins were unchanged throughout the entire period of study. In other cases, neither the number of epileptic attacks nor spike EEG density were apparently affected by this regime and plasma levels of pituitary gonadotropins and gonadal hormones were also unmodified. These results suggest that a latent state of hyperandrogenism may be detected in some epileptic patients with intractable seizures and that chlormadinone may reduce convulsive attacks in these patients, probably by decreasing testosterone plasma levels.
