The present study was designed to explore whether changes occur in psychophysiological variables in healthy women not suffering from premenstrual tension. Variations in electroencephalogram frequencies, reaction time, somatosensory evoked potentials, and nerve conduction velocity were examined in a sample of 30 women, in relation to scores from the Hamilton Psychiatric Rating Scale for Depression and the State-Trait Anxiety Inventory. Trials and recordings were done weekly. EEG frequencies decreased before menstruation in all subjects. However, there were no significant changes for reaction time, nerve conduction velocity, HAMILTON nor State-Trait Anxiety scales associated with subperiods of the menstrual cycle. To explore the impact of anxiety, high and low anxiety groups were formed. The high anxiety group showed the highest scores in the A-Trait form, longer reaction time, enlarged latencies of the P100, but shorter nerve conduction velocity. Anxiety scores as well as reaction time increased during the premenstrual period only for the low anxiety group. The authors conclude that for some women premenstrual anxiety may be related to previous and continuous high levels of anxiety, which associated with some subtle neurological differences as compared with women who rated in low scores for anxiety.

The principal psychiatric syndrome seen in patients with premenstrual tension syndrome is depressive disorder. Questions that should be used to evaluate depression are reviewed and the addition of structured questionnaires for the depressive symptoms is not considered useful in this assessment. Other conditions that may or may not be related to the premenstrual period include psychosis (especially depression and mania), alcoholism, anxiety, and bulimia. Brief questioning concerning these conditions can be performed relatively quickly during the clinical evaluation. Second-source information should be obtained when at all possible. If treatable psychiatric illness is identified in those with premenstrual tension, it should be treated as if the psychiatric syndrome alone were present. There is no indication, however, that such treatment will alter the course of the premenstrual condition should it be present as well.

There is a need to better understand the relationship between premenstrual tension syndrome (PMS) and premenstrual depression. This research was designed to determine if severely depressed women experience a different kind of premenstrual dysfunction than nondepressed PMS patients. The nature and severity of premenstrual symptoms in both groups were evaluated and compared. The severely depressed women were found to have higher PMS scores, but did not differ from the nondepressed group in selection or ranking of symptoms. Depression appeared to influence the patient's perception and rating of symptoms, but the underlying premenstrual dysfunction was identical.

We have observed a high frequency of chronic Candida albicans infection and of allergic sensitization to candida among patients with normocalcemic latent tetany (LT). Among 50 LT patients, 34% suffered from recurrent or chronic candida infection by history, 24% showed evidence of active infection and 48% demonstrated type I hypersensitivity to C. albicans extract on intradermal testing. Treatment with oral antifungal drugs and allergy desensitization to Candida produced complete relief of symptoms in 44% of the patients, with remission occurring for symptoms of depression, irritable bowel syndrome, fatigue, premenstrual tension, headache, anxiety and back pain. The complex relationship between candidiasis and Mg deficit is discussed. Patients with LT, refractory symptoms and a history of prolonged antibiotic exposure or recurrent candida infection should be considered for oral antifungal therapy and candida desensitization.

The authors present a case report that provides support for a relationship between estrogen and the menstrual cycle on the 1 hand and affective disorders on the other. The patient in this case, a 35-year old woman, suffered from a rapid cycling affective disorder that was severely affected by her menstrual cycle and responded positively to oral contraceptives (OCs). The patient had a 24-year history of numerous manic and depressive episodes, the 1st of which coincided with menarche. She had noted that, 4 days before menses, she would experience symptoms of premenstrual tension syndrome (PMS) and often the onset of an affective episode. Treatment with a series of psychotropic agents had not been effective in controlling the number of episodes. However, the patient reported that there had been an 8-9-month period in the past when she had taken OCs and had fewer symptoms. Thus, the patient was placed on Ortho-Novum as well as imipramine. At the 9-month follow-up, she reported there had been no further episodes of depression or mania. The exact mechanism behind estrogen's psychotropic effect is unclear, although it increases the central availability of norepinephrine and induces changes in dopaminergic, noradrenergic, and serotonergic receptors. Beta-endorphin levels covary with estrogen levels, and estrogen seems to affect every major neurotransmitter system. The fact that estrogen has not consistently been shown to be effective in this regard may only signify the existence of a distinct subclass of affective disorders closely linked to the menstrual cycle. This subclass may have some type of dysfunction within the hypothalamic-pituitary-gonadal axis that contributes to mood swings.

Noradrenergic (alpha 1 and beta) and serotonergic (5HT1 and 5HT2) receptors were assayed in the brains of ovariectomized female rats treated for 2 weeks with estrogen, progesterone or a combination of both hormones. Estrogen treatment resulted in a decrease in the number of 5HT1 and beta adrenergic receptors, with a concomitant increase in 5HT2 receptors. Progesterone alone caused a smaller increase in 5HT2 receptors, a similar decrease in 5HT1 and had no significant effect on noradrenergic receptors. When given with estrogen, progesterone blocked the estrogen effect on 5HT2 receptors but did not inhibit the estrogen-mediated decrease in 5HT1 and beta adrenergic receptors. alpha 1 adrenergic receptors were not affected by any of the hormone treatment paradigms. beta adrenergic and 5HT2 receptors are often implicated in antidepressant action, and the modulation of these two receptor types by ovarian hormones might be relevant to hormone-linked affective changes such as premenstrual tension and post-partum depression.

Whether the differences in progestin-estrogen formulations of oral contraceptives (OCs) lead to any clinically significant differences is an important question, even though the concept of "tailoring the pill to the patient" has assumed less importance as the hormonal dosages have decreased. Each component can be evaluated individually, but it is often difficult to predict the result of their combined action. All of the new low-dose formulations contain the same estrogen, ethinyl estradiol (EE). Although the type of progestin in low-dose OCs is probably of little significance for efficacy and cycle control, it may be more important in regard to lipid and carbohydrate metabolism. Combined OC therapy acts simultaneously at various levels of the reproductive system, and contraceptive efficacy of pills with less than 50 mcg of estrogen probably results from these combined actions. The action of estrogen and progesterone is synergistic: the sustained estrogen component exerts negative feedback on gonadotropin secretion, provides stability to the endometrium, and increases the potency of the progestational agent, while progestin can influence only estrogen-primed tissue. The progestin suppresses luteinizing hormone secretion; in addition, progestational influence dominates estrogenic influence in affecting the remainder of the reproductive system. Previous OC usage may delay pregnancy by several months but does not impair longterm fertility potential or increase congenital anomalies or abortions if conception occurs subsequent to the 1st post-pill cycle. Breakthrough bleeding, which occurs in 15% of users, is the single most frequent cause of pill discontinuation but appears to be of no medical consequence. Breakthrough bleeding and amenorrhea may be controlled by changing the pill formulation. Depression has been reported in 5% of OC users, but pill use appears to alleviate premenstrual tension. The individual patient's risk-benefit ratio must be considered when noncontraceptive uses of the pill are contemplated. OC use has been cited as a cure for dysmenorrhea, although the mechanism is uncertain. The possible preservation of fertility or prevention of progression of endometriosis with cyclic pill use should be investigated. The controlled sloughing of a uniformily thinning endometrium prevents and controls dysfunctional uterine bleeding, endometrial hyperplasia, and the anemia that results. Use of OCs has been recommended in treatment of hirsutism to suppress ovarian function when the hypersecretion of androgens is documented. Since both adrenal and ovarian androgens are often involved in hirsutism, the combined suppressive actions of OCs frequently are beneficial. Estrogens also decrease sebum production and often result in indirect acne improvement. Cyclic estrogen-progesterone therapy is recommended for inducing sexual maturation in primary amenorrhea secondary to gonadal failure.

The premenstrual symptom complex many women experience in a moderate to severe form can be divided into four subgroups. Because there is more than one syndrome and nervous tension is one of the most common symptoms, the term premenstrual tension syndromes (PMTS) is used. The most common subgroup, PMT-A, consists of premenstrual anxiety, irritability and nervous tension, sometimes expressed in behavior patterns detrimental to self, family and society. Elevated blood estrogen and low progesterone have been observed in this subgroup. Administration of vitamin B6 at doses of 200-800 mg/day reduces blood estrogen, increases progesterone and results in improved symptoms under double-blind conditions. Women in this subgroup consume an excessive amount of dairy products and refined sugar, and progesterone may be of value in them. The second-most-common subgroup, PMT-H, is associated with symptoms of water and salt retention, abdominal bloating, mastalgia and weight gain. The severe form of PMT-H is associated with elevated serum aldosterone. Vitamin B6 at high dosage suppresses aldosterone and results in diuresis and clinical improvement. Vitamin E helps the breast symptoms. Methylxanthines and nicotine should be curtailed and sodium limited to 3 gm/day. PMT-C is characterized by premenstrual craving for sweets, increased appetite and indulgence in eating refined sugar followed by palpitation, fatigue, fainting spells, headache and sometimes the shakes. PMT-C patients have increased carbohydrate tolerance and low red-cell magnesium. Adequate magnesium replacement results in improved glucose tolerance tests and decreased PMT-C symptoms. Deficiency of the prostaglandin PGE1 may also be involved in PMT-C. PMT-D is the least common but most dangerous because suicide is most frequent in this subgroup. The symptoms are depression, withdrawal, insomnia, forgetfulness and confusion. In ten PMT-D patients the mean blood estrogen was lower and the mean blood progesterone higher than normal during the midluteal phase. Elevated adrenal androgens are observed in some hirsute PMT-D patients. Two PMT-D patients with normal blood progesterone and estrogens had high lead levels in hair tissue and chronic lead intoxication. This subgroups needs careful medical attention when the symptoms are severe. Therapy should be individualized according to the results of the evaluation.

A menstrual symptom questionnaire was used to assess the incidence of premenstrual tension (PMT) in 1,395 regularly menstruating women not on hormonal contraceptives or any other hormonal therapy during routine visits to a gynecologic clinic. Nineteen symptoms were divided into four PMT subgroups: PMT-A (anxiety, irritability, mood swings, nervous tension), PMT-H (weight gain, swelling of extremities, breast tenderness, abdominal bloating), PMT-C (headache, craving for sweets, increased appetite, heart pounding, fatigue and dizziness or fainting) and PMT-D (depression, forgetfulness, crying, confusion, insomnia). The ages of the patients ranged from 13 to 54 years, with a mean +/- S.D. of 32 +/- 8.5 years. Using strict criteria for PMT, 702 patients scored positive for at least one subgroup of PMT, giving an incidence of 50%. When the patients were divided into five-year age groups, a peak incidence of 60% was observed in the third decade of life. The most common PMT subgroups were PMT-A and PMT-H, occurring either alone or in combination. The least common subgroup was PMT-D, occurring in only 12 patients and by itself. The mean cycle length in pure PMT-D patients was significantly shorter (p less than 0.05) than in patients without PMT.
