Bipolar manic-depressive illness is a chronic disease in which patients experience recurrent episodes of mania and depression. Patients often change from a nonverbal, retarded depression of many months' duration to a hyperactive, psychotic, manic condition during the switch. The time required for the switch from depression into mania varies from 5 minutes to a couple of days. Just before it happens, pateints experience marked insomnia and decreased rapid eye movement sleep. It is hypothesized that specific changes in brain monoamine metabolism precede the switch. Alterations in neurotransmitter metabolites, as measured in urine and cerebrospinal fluid, may precede and accompany it. The switch into mania can be precipitated by environmental stresses or by drugs that act by increasing functional brain monoamines. Drugs that reverse the manic state all share the common property of affecting biogenic amines. The switch into mania is viewed in the context of a longitudinal cyclic process and may be further studied with specific pharmacologic agents that block drug-induced maniclike states in man.

Forty two patients (22 adults and 20 children or adolescents) with cerebral dysrithmia were included in a therapeutic trial using barbexaclone: 28 patients suffered from grand mal crises, 2 had associated GM and petit mal and 12 showed disturbances of behaviour without clinical crises. The patients were observed from 6 to 13 months. Four patients failed to complete the trial due to various side effects; 25 patients with GM and 11 with behaviour disturbances showed a very good response; two patients with associated petit mal failed to show any improvement. Side effects such as insomnia and irritability were seen in 8 patients. The authors concluded that barbexaclone is an excellent therapeutic agent in the treatment of grand mal and in patients with behaviour disturbances without convulsive crises.

The term addictive as used by the popular press frequently confuses the more precise concepts of acute and chronic tolerance, physical dependence and withdrawal, and psychologic dependence. Serious physical dependence on psychoactive drugs is rare and is easily managed. In contrast, psychologic dependence, the most important reason for persistent drug use, is much more common and is difficult to treat. Some tactics are available - for example, confrontation and discussion with the patient about how a drug is not going to be effective over long periods. Treating the symptom of a complex problem should, of course, not be expected to solve the problem. The most important tactic is to prescribe dependence-associated drugs only when clearly indicated, when the problem is responsive to drug therapy and for the shortest period necessary, without the option for renewing the prescription. Many problems related to drug use long after the period of expected benefit is past can be avoided by far more restrictive drug prescribing. Barbiturates and nonbarbiturate sedative hypnotics (e.g., ethchlorvynol, glutethimide, meprobamate, methaqualone and methyprylon) should not be prescribed for insomnia, acute reactive anxiety, chronic anxiety neurosis or depressive illnesses, since the safer and equally effective benzodiazepines, which are less associated with dependence, are available.

Intermittent hyperthyreosis occurs under various forms of stress, especially heat stress. The clinician may diagnose such cases as masked or apathetic hyperthyroidism or "forme fruste" hyperthyreosis or thyroid autonomy. As most routine and standard tests may here yield inconsistent results, it is the patients' anamnesis which may provide the clue. Our Bioclimatology Unit has now seen over 100 cases in which thyroid hypersensitivity towards heat was the most prominent syndrome: 10-15% of weather-sensitive patients are affected. The patients complain before or during heat spells of such contradictory symptoms as insomnia, irritability, tension, tachycardia, palpitations, precordial pain, dyspnoe, flushes with sweating or chills, tremor, abdominal pain or diarrhea, polyuria or pollakisuria, weight loss in spite of ravenous appetite, fatigue, exhaustion, depression, adynamia, lack of concentration and confusion. Determination of urinary neurohormones allows a differential diagnosis, intermittent hyperthyreosis being characterized by three cardinal symptoms: 1. tachycardia -- every case with more than 80 pulse beats being suspect (not specific); 2. urinary histamine -- every case excreting more than 90 mug/day being suspect. Again the drawback of this test is its lack of specificity, as histamine may also be increased in cases of allergy and spondylitis; 3. urinary thyroxine -- every case excreting more than 20 mug/day T-4 being suspect. This is the only specific test. Therapy should make use of lithium carbonate and beta-blockers. Propyl thiouracil is rarely required.

Flurazepam hydrochloride was experimented on 43 patients aged 33-83 yr with various forms of insomnia over a period of 4 to 23 days (mean 11.66). There were no changes in the laboratory data and gastroenteric tolerance was also excellent. Chi-square analysis showed that both the quantity and quality of sleep were significantly improved (P less than 0,001). There was no evidence of assuefaction or withdrawal symptoms.

The introduction of a computerized medical information system as part of a project assessing quality in primary care required the coding of drugs prescribed. The development of a simple four-digit system is described, coding drug, therapeutic class, and route of administration. The system allows easy measurement of the use of combined preparations.The drugs used for insomnia and acute bronchitis have been analysed. The results show marked variation with the age of the patient.The potential for medical audit is discussed as it is now possible to link prescribing figures in routine primary care with relevant clinical information.

In this report, the treatment of a 42-year-old female with a complaint of chronic sleep-onset insomnia is described. Following the unsuccessful use of relaxation training, treatment consisted of 11 sessions of EEG theta rhythm (4--7 Hz) biofeedback. Theta density and five sleep indices were monitored throughout baseline, placebo, and treatment sessions. A significant increase in theta density was accompanied by reports of a decrease in sleep latency and an increase in total sleep time. This improvement was maintained after withdrawal of medication and at 3-month follow-up.

Eight patients with mild-to-moderate chronic obstructive pulmonary disease (COPD) and average resting Pao2 of 66 mm Hg were studied clinically and physiologically at sea level and after ascent to 1,920 m. At sea level the patients were symptomatic but not disabled. After ascent the patients had only mild symptoms of fatigue and insomnia, and one had severe headache during exercise on the first day. Funduscopic changes were not observed, nor did cardiac or pulmonary findings change. Resting sea level Pao2 dropped to 51.5 mm Hg within three hours of ascent, and the Paco2 fell from 37.8 to 33.9 mm Hg. Over the next three days, the Pao2 increased to 54.5 mm Hg as hyperventilation continued. At exercise, sea level Pao2 dropped from a mean value of 63 to 46.8 mm Hg at altitude. Pulse rates at rest or exercise did not change. Normal values for 2,3-diphosphoglycerate (2,3-DPG) did not change after ascent at 16 and 42 hours. We believe aircraft flight or travel to moderate altitudes for this type of COPD patient is safe. Preexisting hypoxemia resulting from disease may facilitate the adaptation of patients to severe hypoxia and may prevent symptoms similar to acute mountain sickness.

This clinical study of 62 patients with restless legs syndrome and associated anxious-depressed and other clinical states seems to indicate that caffeine is the major etiological factor in the causation of the restless legs syndrome. Anxiety, while modifying the subjective experience of the dysphoric sensation of restless legs, is not a causative factor. Caffeine is responsible for the increased nervous system arousal as well as for the direct peripheral contractile effect on the striated muscle. This arousal is often reflected psychologically in anxiety and sometimes depressive manifestations, insomnia, heightened proprioceptive awareness and physiologically in the toxic sensory experience of restless legs associated with increased neuromuscular reactivity which may include myoclonus and myokomia.

A survey on rate of illness among 10 500 tourists returning from the tropics and a control group of 1300 from the United States and Canada was performed by a questionnaire completed during the flight back to Switzerland. Only 25% from southern destinations, but 53% from North America, were never incapacitated during their travels. The vast majority of the illnesses were of no consequence, as was reflected by a low rate for bed confinement of 4% and 1% respectively. The most frequent symptoms in the tropics were diarrhea in 34% (mostly of short duration and mild degree), constipation in 14%, upper respiratory illness in 12% and insomnia in 11%. There were significant differences according to sex, age and tropical experience. The influence on pre-existing diseases was assessed. 7% of the tourists returning from the tropics were sick in the course of the year following the journey.
