The purpose of the study was to explore personal fears about AIDS and their consequences in terms of psychological symptoms and behaviour. 1902 individuals, 15 to 64 years old, were selected at random from the Finnish population and interviewed by telephone (94%) or in person (6%). 2.5% regarded AIDS as a personal threat, while 12-13% exhibited psychological symptoms such as insomnia, depression, anxiety or episodes of fear. About 20% had taken measures to prevent HIV infection: 9% had increased their use of condoms, 6% had had themselves tested for HIV, and 5% had taken precautionary measures at work. The psychological status of individuals who feel at risk of AIDS should be assessed within the health care system because persistent feelings of danger may be a sign of incipient psychological decompensation.

A cross-sectional study of insomnia and hypnotic use was performed in a sample of the French population. The quota method was used to select the sample of 1,003 subjects, with less than 3% substitution. Subjects were 15 years old and older and were representative of the French population based on gender, age, marital status and living environment. Subjects were asked questions relevant to the complaint of insomnia and hypnotic use and filled out questionnaires measuring anxiety and depression. The complaint of insomnia is common, even in the 15-24-year-old group. Overall, more women than men were afflicted. The largest group of insomniac subjects, and the group who most often used hypnotics "frequently and chronically", were women 45 years and older. Men presented a sharp increase in hypnotic use after 65 years of age. Ten percent of the entire sample used hypnotics, 8% for more than 6 months and 6.17% on a chronic and frequent basis. Retired and unemployed elderly were also chronic and frequent hypnotic users: aging and social isolation correlate with chronic and frequent hypnotic usage. Higher scores on anxiety and depression scales correlate with more frequent complaints of nocturnal sleep disturbances. Young individuals are a significant complainer group but use hypnotics rarely. A rural environment was associated, overall, with fewer insomnia complaints, but environment had much less impact on complaints and hypnotic use in the elderly than in other age groups. One may question whether, in the French population, hypnotic prescription and intake are not responses to a social rather than a medical problem.

In an epidemiological population study 87 subjects were studied with home sleep recordings. Nineteen subjects had minor psychiatric disorders: six subjects had a minor depression, six subjects had a generalized anxiety disorder, and seven subjects had a mild vegetative discomfort syndrome. Syndrome profiles of the three groups, using the AMDP system, showed a significantly higher degree of insomnia in the anxiety group than in the depressive group. The mean rapid eye movement (REM) latency in the anxiety group was significantly longer than in the other groups, including normals. The study showed a slight tendency towards a reduced REM latency in the minor depressives, but no statistical significance was obtained.

Epidemiological studies and studies of clinical populations suggest that there are primarily two opposite patterns of seasonally recurring depressions: summer depression and winter depression. In addition, there is preliminary evidence that the two seasonal types of depression may have opposite types of vegetative symptoms. In the present study, we prospectively monitored symptoms of depression in 30 patients with recurrent summer depression and 30 sex-matched patients with recurrent winter depression and compared the symptom profiles of the two groups. Consistent with predictions based on the earlier reports, we found that winter depressives were more likely to have atypical vegetative symptoms, with increased appetite, carbohydrate craving, weight gain and hypersomnia, and that summer depressives were more likely to have endogenous vegetative symptoms, with decreased appetite and insomnia. A cluster analysis performed on the patients' symptom profiles without reference to season of occurrence of their episodes separated 78% of the summer depressives and winter depressives from each other on the basis of their symptoms (chi 2 = 19.29, P less than 0.001).

Three 6-8 week comparative studies have shown sertraline to be an effective, safe and well-tolerated treatment for acute depressive illness. The first, a double-blind fixed-dose study, demonstrated the efficacy of sertraline over placebo; the second, a forced upward titration, active- and placebo-controlled, double-blind study, showed that sertraline was of equal efficacy to amitriptyline. The third was a double-blind comparison of sertraline and amitriptyline in elderly depressives, with the dose being increased as necessary and as tolerated. The overall results showed sertraline to be consistently superior to placebo and equivalent in therapeutic effect to amitriptyline on a number of measures including depression, anxiety, insomnia and suicidal ideation. Efficacy was found in both moderately and severely depressed patients whose primary psychiatric diagnoses included single-episode and recurrent major depression, with and without melancholia. Sertraline was also found to be effective in patients with a high baseline anxiety score on the Hamilton Rating Scale for Depression.

Depression is highly prevalent in the elderly and there are difficulties with definition and diagnosis. The signs and symptoms of depression may differ from those in younger patients since the elderly are frequently preoccupied with physical ailments and may have more agitation, insomnia and hypochondriasis. The aetiology and cause of depression and its association with psychosocial and other risk factors are discussed, with particular reference to masked depression, depressive delusional illness and 'pseudo dementia'. A range of treatments have been used in depressive patients, including psychotherapy, cognitive therapy, ECT and various drug treatments. In the elderly drugs may cause more problems than in younger patients. These can be divided into those associated with: pharmacokinetics, polypharmacy, side effects, dosage and lethality. Trials of antidepressants in the elderly are discussed and include trials with tricyclic antidepressants, monoamine oxidase inhibitors and SSRIs. Particular reference is made to a trial of fluvoxamine versus mianserin in the elderly, which demonstrated that fluvoxamine is as effective as mianserin in treating depression, and has fewer side effects.

In order to assess the predictive value of somatic and biological factors in antidepressant trials, non specific parameters, i.e. natural course of illness, life events, placebo effect ... have to be controlled by means of studies vs placebo. Among somatic factors, retardation seems to predict a positive response to antidepressants. The predictive value of other endogenous signs--like insomnia or weight loss--is still questioned. Few biochemical parameters appear relevant when metabolites of central monoamines, their precursors and the enzymatic processes involved are considered. The serotoninergic system is the focus of many studies. Among the neuroendocrine indices, the DST proved too poorly specific of depression. Among the physiological parameters, some characteristics of sleep EEG, like a shortening of REM latency, seem promising. Pharmacological challenges, for instance response to stimulant drugs, gave inconsistent results and should be discussed on ethical grounds. Many studies have been undertaken but presently no routine reliable biological index is available to predict a response to antidepressants.

During the last decade the development of a great amount of knowledge about the menopause has allowed to establish almost standardized hormonal treatments in order to prevent its symptoms and its late sequelae. Nevertheless, up to now the relationship between typical climacteric symptoms and the actual risk of late sequelae has not been assessed. The climacteric symptoms have hence been related to the involutional aspects of the external genitalia and to the levels of the sex steroids and gonadotropin hormones. An inverse relation between neuropsychical manifestations (insomnia, anxiety, depression, reduced memory, reduced libido) and 17-beta-oestradiol and progesterone levels has been shown. On the contrary, FSH and LH levels showed a direct relationship with neurovegetative symptoms. The relationship between the involutional aspects of the external genitalia and the atrophy related and the neuropsychical symptoms shows the need to evaluate these classes of symptoms, which appear to be most related to oestrogen and progesterone deprivation, in decision making toward hormonal replacement therapy.

The physiological imbalances associated with organ insufficiency and the complexity of organ transplant surgery and postoperative care puts patients at risk for psychiatric disorders. The brain is susceptible to a variety of insults as a result of these complex processes, including those secondary to medications and infections. We review literature relevant to organ transplant patients and also include empirical knowledge based on clinical practice. We first describe the physiologic and psychiatric issues for each major organ that is commonly transplanted, including liver, kidney, heart, bone marrow, and pancreas, as well as multiple organ transplantation. We then discuss the pharmacologic treatment and neuropsychiatric side effects of rejection with various immunosuppressants, including cyclosporine, azathioprine, OKT3, FK506, and corticosteroids. Certain bacterial, fungal, viral, and protozoal infections occur more frequently in the transplant population; their relationship to neuropsychiatric dysfunction is discussed. We then present details of psychopharmacotherapy of delirium, other organic mental disorders, depression, mania, anxiety, and insomnia, with attention to drug interactions and differential diagnosis. Particularly cautious monitoring of medication doses and serum levels is recommended in these patients.

P3 latency, a brain event-related potential (ERP) correlate of stimulus evaluation time, was measured in 25 unmedicated depressed patients and 27 normal controls during auditory temporal and spatial discrimination tasks. Patients were divided into two subgroups, one having a typical major depression (melancholia or simple mood reactive depression) and one having an atypical depression. Typical depressives had abnormally long P3 latency for the spatial task but not the temporal task. They also showed an abnormal lateral asymmetry, with longer P3 latency for stimuli in the right hemifield than the left. In contrast, atypical depressives did not differ from normals in either respect. Longer P3 latency correlated with ratings of insomnia, while abnormal lateral asymmetry correlated with reduced right visual field advantage for syllables. The P3 latency findings point to a task-related slowing of perceptual decisions in a subgroup of depression.
