To clarify the mechanisms of gender-related mind/body relationships, the authors analyzed the characteristics of 1,132 outpatients (848 women and 284 men) attending a mind/body medicine clinic. At entry in the program, the patients completed the Medical Symptom Checklist, Symptom Checklist-90 revised (SCL-90R), and Stress Perception Scale. Women reported 9 out of 12 symptoms (fatigue, insomnia, headache, back pain, joint or limb pain, palpitations, constipation, nausea, and dizziness) more frequently than the men did. Being a woman was a predictor of the total number of somatic symptoms endorsed. SCL-90R somatization scores were significantly higher in nonmarried women than in married women. Perceived stress ratings of family and health were higher in women than in men, despite the lower degree of perceived stress concerning work. Women, especially nonmarried women, were more likely to report somatic discomfort. Gender appears to be an important factor in relation to the report of somatic symptoms in stress-related conditions.

The mainstay of treatment is a specialized form of physical therapy that intentionally induces symptoms of dizziness with head movements, moving visual targets, and changes in position. Patients must be motivated to experience discomfort during the early stages of rehabilitation, doing the types of activities that they likely have been avoiding. Time must be spent convincing the patient of the necessity to deliberately provoke dizziness in order for the exercises to work. It is important to not overmedicate with vestibular suppressants, and to treat any co-existing mood or anxiety disorder, as these interfere with the adaptive plasticity that is the basis of successful rehabilitation.

A survey study using questionnaire was conducted in 530 people (270 men, 260 women) living or not in vicinity of cellular phone base stations, on 18 Non Specific Health Symptoms. Comparisons of complaints frequencies (CHI-SQUARE test with Yates correction) in relation with distance from base station and sex, show significant (p < 0.05) increase as compared to people living > 300 m or not exposed to base station, till 300 m for tiredness, 200 m for headache, sleep disturbance, discomfort, etc. 100 m for irritability, depression, loss of memory, dizziness, libido decrease, etc. Women significantly more often than men (p < 0.05) complained of headache, nausea, loss of appetite, sleep disturbance, depression, discomfort and visual perturbations. This first study on symptoms experienced by people living in vicinity of base stations shows that, in view of radioprotection, minimal distance of people from cellular phone base stations should not be < 300 m.

Reactions to oral contraceptive therapy tend to be maximal during the first few months of use. They include nausea or epigastric discomfort, malaise, dizziness, nervousness, fatigue, weakness, leg cramps, headache, and depression. The estrogenic component is thought to be the cause. There may also be a psychogenic basis reflecting apprehension. Breast tenderness is an occasional complaint and intermenstrual spotting or breakthrough bleeding is often reported. Increasing dosage has reduced this symptom. Dysmenorrhea prior to treatment may be improved but occasionally it is aggravated. Drug-induced amenorrhea presents a double problem in that failure to resume medication 7 days after completion of a cycle results in a risk of conception. Episodes of severe uterine bleeding in patients discontinuing use after several months or years have been reported. Other side effects include a skin reaction resembling acne, pruritus, hirsutism, thinning of scalp hair, increased skin pigmentation, and weight gain or loss. Serious vascular complications and hepatic dysfunction have been shown and deviation of thyroid function may be shown by increase of serum protein-bound iodine (PBI). Clinical signs of hyperthyroidism have not been described. Oral contraception is associated with elevated plasma cortisol (hydrocortisone) levels and decreased urinary levels of 17-hydroxycorticosteroids (17-OCHS). Suppression of ovarian activity by oral contraceptives is rapidly reversible. Fear of carcinogenesis has caused much alarm but no proof as of the present time. Safety of long term use will require additional years of experience.

In the 1974-86 period, gossypol acetate was taken as an antifertility measure by 16 men. The initial dose was 20 mg/day, with a maintenance dose of 40 mg/week. Antifertility efficacy was obtained in all 16 cases. Azoospermia persisted in 1 case where the gossypol had been taken for 8 years and discontinued for the past 2 1/2 years. Symptoms experienced in the first 2 weeks of gossypol acetate administration included dizziness, anorexia, nausea, fatigue, and stomach discomfort. Results of examinations of blood and urine; functions of the heart, liver, lung, and liver; electrolytes; external genitalia; and sexual performance were all in the normal range. Measurements of semen, plasma biochemistry, and endocrine changes also were within normal limits. However, in the 9 cases in which the average value of plasma testosterone was near the lower limit of normal, the average value of follicle-stimulating hormone was higher than normal and the testosterone/luteinizing hormone ratio was unusually low. Testis biopsy indicated that long-term gossypol treatment affected both germ cells and Sertoli cells. Leydig cells also demonstrated some damage. Gossypol acetate is, in general, considered an ideal male contraceptive because of its long-term effectiveness, reversibility, and lack of severe toxic side effects.

The acceptability and effectiveness of a progestogen-only oral contraceptive (OC), Ovrette, during lactation were investigated in 200 women recruited from a teaching hospital in Khartoum, Sudan. Ovrette contained 0.075 mg of norgestrel. 69 women (34.5%) had used OCs at some point prior to the index pregnancy. Serious complications (e.g., severe headache, chest pain, leg pain, abdominal pain, blurred vision) were reported by 8 respondents during the 12-month study period. Less serious side effects included dysmenorrhea (49 women), nausea (28 women), dizziness (38 women), vaginal discharge (86 women), headaches (78 women), and breast discomfort (21 women). Overall, 143 women (71.5%) experienced at least 1 side effect. Of the 21 women (10.5%) who discontinued Ovrette use before 12 months, 9 were motivated by menstrual problems and other side effects. The 12-month continuation rate was 89.1%. There were 2 pregnancies, only 1 of which represented method failure. These findings are consistent with previous studies indicating that use of progestin contraceptive agents is associated with more menstrual disturbances and pregnancies than combined OCs. Use of combined OCs is contraindicated during lactation, however.

FDA has approved medroxyprogesterone acetate as Depo Provera Contraceptive Injection, effective for 3 months in preventing pregnancy in women. In clinical studies, the drug's failure rate was less than 1%. However, physicians must ensure that patients receive injections on schedule to prevent pregnancy. The recommended dose is 150 mg administered every 3 months by deep, intramuscular injection in the gluteal or deltoid muscle. Most women in clinical studies of Depo Provera experienced menstrual irregularities. As use continued, amenorrhea became common, reported by 57% of the women by the end of a year of treatment. Other side effects included weight gain, headache, nervousness, abdominal pain or discomfort, dizziness, and asthenia. Physicians should administer the drug only to women found not to be pregnant, because fetal exposure may lead to low birth weight and other problems. Recent data have demonstrated that longterm use may contribute to osteoporosis, and the drug's manufacturer, the Upjohn Company of Kalamazoo, Michigan, will conduct additional research to study this possible side effect. Contraindications are similar to those for other contraceptives and include undiagnosed vaginal bleeding, known or suspected malignancy of breast, thromboembolic disorders, cerebral vascular disease, and liver dysfunction. Depo Provera was developed in the 1960s and has been approved for contraception in many other countries. When FDA first reviewed data on the drug in the 1970s, animal studies raised questions about its potential to cause breast cancer. Since then, longterm controlled clinical studies in other countries have shown a risk of breast cancer comparable to oral contraceptives, and no increased risk for ovarian, liver, or cervical cancer. The studies also showed that the contraceptive injection reduced the risk of endometrial cancer. FDA approved the drug October 29, 1992.

Kava and valerian are herbal remedies that are claimed to have anxiolytic and sedative properties respectively, without dependence potential or any appreciable side effects. In this pilot study, 24 patients suffering from stress-induced insomnia were treated for 6 weeks with kava (LI-150), 120 mg daily. This was followed by a 2-week 'wash-out' period off treatment, and then, five patients having dropped out, 19 received valerian (LI-156), 600 mg daily, for another 6 weeks. Then there was a further 2-week period off treatment, and a final 6 weeks of treatment of these 19 patients with the two compounds combined (kava + valerian). Stress was measured in three areas: social, personal and life events; insomnia in three areas also: time to fall asleep, hours slept and waking mood. Total stress severity was significantly relieved by both compounds individually (p < 0.01), with no significant differences between them; and there was also improvement with the combination, significant in the case of insomnia (p < 0.05). On direct questioning, 16 patients (67%) reported no side effects on kava, 10 (53%) on valerian and 10 (53%) on the combination. The 'commonest' effect was vivid dreams with kava + valerian (4 cases (21%)) and with valerian alone (3 cases (16%)), followed by gastric discomfort and dizziness with kava (3 cases each (3 %)). These results are considered to be extremely promising but further studies may be required to determine the relative roles of the two compounds for such indications.

The aim of this study was to investigate whether a tympanic displacement analyser could detect decreases in cerebral blood flow and intracranial pressure after administration of indomethacin in healthy volunteers. In a double-blind crossover study involving 14 healthy volunteers all subjects first underwent a test-retest evaluation to investigate reproducibility followed by tests performed in sitting and supine positions to confirm intracranial-cochlear pressure transfer. In two further sessions tests were performed before and 90 min after subjects were blindly administered a suppository containing either 100 mg of indomethacin or placebo. It was found that tympanic membrane analysis performed 90 min after administration of such a suppository did not mirror the induced reduction in cerebral blood flow after administration of active drug. After administration of indomethacin eight of the subjects experienced discomfort and dizziness; after placebo none experienced subjective symptoms. After administration of indomethacin a statistically significant decrease in heart rate was demonstrated. The exponential form of the intracranial pressure-volume curve may explain why a decrease in intracranial pressure was not detected using the tympanic membrane displacement method, because the measurements were made in subjects with normal intracranial pressure. More significant findings may be found in patients with elevated intracranial pressure.

A 57-year-old man consulted an herbalist for epigastric discomfort. Four hours after he drank a decoction made from 14 herbs, he developed nausea, epigastric pain, and dizziness. He also had two loose bowel movements. On arrival at the hospital 4 hours later, his blood pressure was 77/46 mm Hg, and his pulse was 60 beats/min. He was given intravenous fluids. In the next 3 hours, his blood pressure gradually returned to his usual level of 100/65 mm Hg. His other gastrointestinal symptoms gradually subsided during the next 24 hours. His white cell count was 17.8 x 109/L but was normal on recheck. Complete cell counts, renal function and liver function tests, and electrocardiogram were otherwise normal. He was discharged home on day 2. Seven of the 14 herbs taken by this patient are known to have vasodilatory or blood pressure-lowering effects, and 3 of these herbs are used to manage hypertension. In traditional Chinese medicine, practitioners often use a combination of herbs in an attempt to improve the efficacy but reduce the adverse effects of treatment. The risk of adverse herbal interactions will also be higher.
