The present investigation was undertaken to establish the relation between climacteric symptoms, ovarian function, ageing, and psychological factors. The subjects were as follows; 1,270 women who received a screening test for cervical cancer and 247 women following hysterectomy. The methods of investigation were Kupperman menopausal index (K-index), Cornell Medical Index (CMI) and YG character questionnaire (YG test). The following results were obtained: 1) the K-index increased until 39 years of age and was constant after 40 years. Five symptoms (chills, nervousness, melancholia, excitability and vertigo) were not influenced by ageing, and seven symptoms (panting, hypesthesia, insomnia, wakefulness, fatigue, palpitation and formication) increased with age. Hot flushes, perspiration, numbness, shoulder stiffness, lumbago, and headache, occurred at peak frequency in the climacteric period. 2) In hot flushes, perspiration, numbness, hypesthesia, shoulder stiffness, lumbago, and formication, a significant difference was found between the control and those patients who had received bilateral oophorectomy. 3) The K-index and CMI score were significantly correlated, and six symptoms (palpitation, panting, excitability, vertigo, wakefulness and formication) in particular were related to CMI. 4) The K-index was lowest in the patients indicated to be the D type by the YG test, and was highest in the patients of the B.E type. Six symptoms (excitability, palpitation, panting, melanchoria, hypesthesia and formication) were thought to be associated with the character of the patients. Results showed that four symptoms (hot flushes, perspiration, numbness, shoulder stiffness and lumbago) were closely related to ovarian function, and three symptoms (panting, excitability, and palpitation) depended largely on mental factors. The relationship between vasomortor symptoms and gonadotropin was investigated.(ABSTRACT TRUNCATED AT 250 WORDS)

The purine analog 2',3'-dideoxyinosine (ddI), which has anti-retroviral activity in vitro was administered for up to 42 weeks to 26 patients with acquired immunodeficiency syndrome (AIDS) or severe AIDS-related complex (ARC). Ten of these individuals were AZT-intolerant. Eight dose regimens were studied. The drug was orally bioavailable and penetrated into the cerebrospinal fluid (CSF). Comparatively little evidence of an effect against human immunodeficiency virus (HIV) was seen at the lowest four doses. However, patients in the four highest dose groups (ddI at 1.6 milligrams per kilogram intravenously and then greater than or equal to 3.2 milligrams per kilogram orally at least every 12 hours or higher) had increases in their circulating CD4+ T cells (P less than 0.0005), increased CD4/CD8 T cell ratios (P less than 0.01), and, where evaluable, more than an 80% decrease in serum HIV p24 antigen (P less than 0.05). The patients also had evidence of improved immunologic function, had reduced viremic symptomatology, and gained a mean of 1.6 kilogram with these comparatively infrequent dosing schedules (every 8 or 12 hours). The most notable adverse effects directly attributable to ddI administration at the doses used in this study included increases in serum uric acid (due to hypoxanthine release) and mild headaches and insomnia. These results suggest that serious short-term toxicity at therapeutic doses is not an inherent feature in the profile of agents with clinical anti-HIV activity. Further controlled studies to define the safety and efficacy of this agent may be worth considering.

Single oral doses of 10 to 160 mg centpropazine, a new antidepressant (synthesized by CDRI, Lucknow, India) were administered to groups of 4-5 male volunteers, each dose being interspersed with placebo in a double blind, non-crossover study by random distribution. The drug was well tolerated. Drowsiness, heaviness, weakness and/or headache were reported only at doses of 120 mg and above. No adverse effect was noted in various laboratory tests, ECG or vital parameters. In a multiple dose study, volunteers received 40 or 80 mg centpropazine daily for 4 wk. Mild restlessness and insomnia were observed in some subjects receiving 80 mg dose. In this study also no effect was observed in various laboratory tests, ECG or vital parameters.

Since the introduction of fenofibrate to European clinical practice in 1975, some 6.5 million patient-years of experience in the treatment of hyperlipidemia have been accumulated. A review of results of clinical trials shows fenofibrate to have a broad spectrum of lipid-lowering activity, reducing the total cholesterol level by 20-25% in type IIa patients and triglycerides by 40-60% in type IIb and IV patients. High levels of low-density lipoprotein cholesterol are reduced and, where low at baseline, high-density lipoprotein levels are increased. An associated activity is a 10-28% reduction in serum uric acid levels. Adverse reactions in the mostly open clinical trials ranged from 2-15%; mild gastrointestinal problems dominated, and occurred with much the same frequency in the placebo-treated groups of controlled trials. There are also reports of fatigue, headache, loss of libido, dizziness, and insomnia. Some excess of skin rash emerged as the only statistically significant unwanted clinical effect in one placebo-controlled trial. Biochemically, there are occasional fluctuations in serum transaminase values, while gamma-glucuronyl transferase and alkaline phosphatase are often decreased, all without apparent clinical significance. Lithogenicity of the bile is often increased above pretreatment levels, but there is no evidence from trials or postmarketing surveillance that the use of fenofibrate is associated with an increase of gallstone formation.

Zidovudine (azidothymidine) is a thymidine analogue antiretroviral drug active against human immunodeficiency virus (HIV). In acquired immunodeficiency syndrome (AIDS) and AIDS-related complex (ARC) patients, orally and intravenously administered zidovudine is effective in reducing the incidence of opportunistic infections and neoplasms, increasing helper T lymphocyte numbers, and improving survival rates and quality of life. Adverse effects include serious haematological abnormalities and severe headache, abdominal discomfort, nausea, myalgia and insomnia. In addition, neutropenia and other anaemias frequently limit zidovudine therapy and may result in a need for multiple blood transfusions, dose reductions or withdrawal of the drug. However, despite these problems and the lack of information about some aspects of zidovudine use, zidovudine provides a major hope for HIV-infected patients, and it has rapidly become the standard therapy for improving the quality and duration of the lives of AIDS and ARC patients.

Forty-eight experimental studies of nonmechanically assisted relaxation techniques used to control a variety of clinical symptoms were synthesized using meta-analysis. Effect sizes for three types of comparisons, experimental-control, experimental-placebo, and pre-post, ranged from .43 to .66, demonstrating that treatment of any type included in the analysis moved the client from the 50th to the 67th percentile of an untreated group at minimum and from the 50th to the 75th percentile at maximum. All treatments included in the analysis except Benson's relaxation technique demonstrated evidence of effectiveness, particularly for nonsurgical samples with chronic problems such as hypertension, headache, and insomnia.

The effect of zolpidem 10 mg p.o. on sleep in patients with persistent psychophysiological insomnia was assessed by polysomnographic recordings. An improvement in sleep with no rebound insomnia was observed during treatment for two weeks. Time awake after the onset of sleep was reduced after one week and increased after two weeks, whereas sleep latency remained reduced. Zolpidem markedly increased the duration of Stage 2 sleep without affecting either slow wave sleep or REM sleep. Subjective evaluation of improvement in sleep was well correlated with sleep laboratory findings. Zolpidem did not impair the immediate memory or psychomotor performance of patients on the morning after its administration. Side-effects during the period of drug administration included drowsiness, fatigue, headache, anxiety and irritability. They were mild or moderate and wore off soon after awakening.

Fluoxetine is an antidepressant drug with a unique chemical configuration which enhances serotoninergic transmission by inhibiting serotonin uptake. The chronic presence of serotonin in the synaptic cleft reduces postsynaptic receptors, a postulated explanation for its antidepressant efficacy. Comparative studies show that the therapeutic effectiveness of fluoxetine is equal to that of imipramine, amitriptyline, and doxepin. A 20 mg morning dose alleviates most depressions. The long half-life of one to three days for the parent compound and seven to 15 days for the active metabolite, desmethylfluoxetine, is largely unaffected by age or renal impairment. Nausea, nervousness, insomnia, and headache are the most common side effects. Therapeutic doses do not affect cardiac conduction or cause orthostasis. A primary benefit of this drug is its significant relative safety in overdoses as compared to other antidepressants.

The effects of pentoxifylline on intermittent claudication were evaluated at a dose of 1200 mg/day in an open-label twelve-week study on geriatric patients with chronic occlusive arterial disease (COAD). Standardized treadmill testing and clinical signs and symptoms of COAD were followed up before and during drug administration. Twenty-four subjects with a mean age of 73.5 years, capable of walking between 20 and 200 meters on the treadmill, were entered into the trial; 22 participated for eight weeks and 19 completed the study in terms of treadmill walking distance measurements at 12 weeks. The mean walking distance for all patients was increased 111% over baseline at week 12. Thirteen subjects were considered drug responders (greater than or equal to 50% increase in treadmill walking distance) and 9 were considered nonresponders (less than 50% increase). Improvements in clinical signs and symptoms of COAD were noted. Decreases in elevated systemic systolic pressures (but not diastolic) were unexpectedly observed in many drug responders. Seven of 19 males reported sexual function improvements while receiving pentoxifylline. Fourteen (58%) of the 24 subjects reported mild side effects of dyspepsia, nausea, vomiting, dizziness, headache, or insomnia; no subjects were withdrawn from the study because of side effects. In summary, pentoxifylline improved function and symptoms in 13 of 22 geriatric patients with intermittent claudication; the drug was safe and well tolerated at the usual dosage in this geriatric patient population.

The safety profile of ofloxacin was evaluated on the basis of adverse reactions and abnormal laboratory values seen in United States clinical trials and phase I studies addressing specific issues. The most frequently reported adverse reactions occurring in 2,197 patients who received three to 10 days of ofloxacin in United States clinical trials were nausea (3.5 percent), insomnia (1.8 percent), headache (1.4 percent), and dizziness (1.2 percent). Adverse reactions were not serious and usually rapidly reversible. The incidence of adverse reactions did not increase with increasing age. There is no clinically significant interaction with methylxanthines (caffeine or theophylline). Crystalluria was not observed. Ofloxacin is a well-tolerated fluoroquinolone antimicrobial agent.
