In the mid-nineteenth century opium and its derivatives, such as laudanum and morphine, were the most common poisons in suicides in England and Wales. With legislative restrictions on these ‘dangerous drugs’ such a use declined. This study attempts to show this trend and indicates the large variety of these opium-related suicides.

A sample of 77 women of high and low noise sensitivity, living in areas of high and low exposure to aircraft noise drawn from the 1977 West London Survey, were interviewed in the community in 1980. Women of high, intermediate and low noise sensitivity in 1980 were compared for measures of psychiatric disorder, personality and reactivity to the other sensory stimuli. In addition, the noise sensitivity measures defining the three groups in 1980 were compared with further measures of noise sensitivity. High noise sensitive women exhibited significantly more psychiatric symptoms, higher neuroticism scores, and greater reactivity to other sensory stimuli than intermediate and low noise sensitive women.

A sample of 77 women of high and low noise sensitivity in 1977, living in areas of high and low exposure to aircraft noise, were interviewed in the community in 1980. High, intermediate and low noise sensitive women were compared, using measures of blood pressure, heart rate, skin conductance, hearing threshold, uncomfortable loudness level and magnitude estimation of six tones. These physiological measures did not clearly distinguish different noise sensitivity groups, except that highly noise sensitive women had a consistently slower heart rate. Noise sensitivity was not related to auditory threshold. In the high aircraft noise area there were significantly more skin conductance responses than in the low aircraft noise area, irrespective of noise sensitivity. This may be the result of chronic exposure to high aircraft noise.

The role of primary care physicians in addressing the needs of chronically mentally ill patients is examined from three perspectives: (1) assessing community prevalence; (2) treating chronic medical problems in the context of other human service needs; and (3) treating specific types of chronic mental disorders. About 30% of primary care patients were found to have at least one Research Diagnostic Criteria mental disorder, five-sixths of which had a duration greater than 1 year. However, about 9% of patients had some impairment and 2% had severe impairment associated with a mental disorder. Although affective disorders have the highest overall rates, personality, psychotic, and anxiety disorders contribute the greatest proportion of severe disability.

While depressive reactions appear to be universal, until recently they have seldom been described outside Europe, probably because of their lack of exotic salience, but also because they are seldom identified locally as distinct entities. Where it occurs, such an identification reflects a local preference for the articulation of individual psychological notions, rather than universal moral imperatives. While the symptoms of reactive depression are recognized in rural Trinidad as a common experience, but not especially remarked, they are also identified by Afro-Caribbeans as a specific state, Tabanka, following the loss of a sexual partner to another. Tabanka is characterized by lassitude, anorexia, insomnia, feelings of worthlessness, anger, a loss of interest in work and other activities and, especially, by a preoccupation with the faithless one. It is said to be most common among married men and among the upwardly socially mobile, and to lead to heavy drinking and occasionally madness or suicide. The precipitation of Tabanka provokes hilarity rather than moral indignation, and its humour articulates an egalitarian and individualistic working-class attitude to marriage and social mobility. In contrast, Trinidadians of Asian or Venezuelan origin emphasize moral notions of honour and shame.

A sample of 1150 unemployed 17 year-olds, containing blacks and whites, males and females, was obtained from 11 urban regions in England. Social support was measured in respect of five different forms of help from others. Measures were also obtained of psychological distress, perceived pressure from others to obtain a job, employment commitment, contact with other young people, and contact with other unemployed young people. Two forms of social support (having someone to turn to for help with money, and having someone to suggest interesting things to do) were significantly associated with measures of distress, as were perceived pressure to obtain a job and employment commitment, but not contact with other unemployed young people. The association between distress and having someone to turn to for help with money was greater for those perceiving pressure from others to obtain a job than those not perceiving pressure. Also, the association between distress and having someone to turn to when feeling low was greater for those with a high employment commitment than for those with a low one. Other associations between support and distress were found to be affected by sex and ethnic differences in the sample. The results are discussed in the light of a stress-buffering model of social support; and the need to disaggregate social support into its component parts is emphasized.

Seventy-one men completed a battery of cognitive tests which were designed to reflect verbal analytic and non-verbal holistic functioning. Interest centred around pattern of response. Thirty men were suffering from an affective disorder and forty-one were well. All the men were in prison, the majority awaiting trial. The affective disorder group was subdivided into three categories: men who had a history of manic-depressive illness; a group of unipolar, psychotically depressed men; and men who were regarded as being depressed in reaction to circumstances. All three groups showed specific difficulty in dealing with spatial/holistic tasks, other factors being held constant. They were also found to differ in a number of other respects. The possible significance of these differences is discussed.

Twenty schizophrenic patients with tardive dyskinesia and an equal number of matched controls were tested on a novel cognitive task. The task had two components: cued response and spatial memory. Relative to controls, the dyskinetic subjects showed a superior cued response performance but an equal spatial memory ability. We speculate that this selective facilitation may reflect dopaminergic hyperactivity in the dyskinetic group.

Depressed patients commonly complain of concentration problems, yet these have seldom been the focus of systematic investigation. A structured interview about concentration problems was administered to a group of relatively severely depressed patients. Problems in reading and watching television were the most common, and were highly correlated with each other. Direct report of the number of concentration lapses on a reading task was the most generally satisfactory task-performance correlate of complaints of reading/TV concentration problems. Evidence both from this task and from the interview suggests that depressive concentration problems may often be due to ‘mind-wandering’. The correlations with concentration problems with the severity and endogeneity of depression and with state anxiety were generally similar.

A study was made of the smoking habits of an unselected series of 1129 18-year-old men from the general population. Their smoking habits were related to personality traits, intellectual level and platelet monoamine oxidase (MAO). Regular smokers were found to be extraverts, sensation seekers who were easily bored and with a strong tendency to avoid monotony. They also had a lower than average intellectual level, and were more prone to the abuse of alcohol, glue, cannabis, amphetamine and morphine. Furthermore, they had a low platelet MAO.

The results are discussed in relation to the pharmacological reasons for smoking and favour the hypothesis that tobacco smoking is related to arousal-seeking behaviour. Ex-smokers had personality traits, intellectual levels and platelet MAO of the same magnitude as non-smokers: this may be the reason why they were able to give up smoking.

The monoamine metabolites 5-hydroxindoleacetic acid (5-HIAA), homovanillic acid (HVA) and 3-methoxy-4-hydroxyphenylethyleneglycol (MHPG) were measured in the lumbar cerebrospinal fluid (CSF) of 27 chronic schizophrenic patients who at some time had attempted suicide, and were compared with values from 27 chronic schizophrenic patients without a history of attempted suicide. There were no significant differences between either the violent or non-violent attempters and those without a history of attempted suicide in the mean lumbar CSF concentrations of the serotonin metabolite 5-HIAA, the dopamine metabolite HVA, or the norepinephrine metabolite MHPG. Significantly more of the suicide attempters had a previous major depressive episode, had received a course of ECT, and had significantly more psychiatric admissions than those who had never attempted suicide.

In a group of 20 patients who were to undergo endarterectomy for atherosclerotic occlusive disease of the internal carotid artery, the stenosis did not appear to have resulted in cognitive or motor deficits. Consistent with this finding, surgery could not be shown to have a beneficial effect on cognitive or motor functioning. Control data were supplied by 20 patients who underwent peripheral vascular surgery and 20 healthy subjects. The test-retest interval was 10 weeks.

Antibodies to a variety of foods, and in particular cereals, were measured in serum from 100 patients with acute psychoses and 100 elective surgical patients. For 13 out of 14 foods to which non-IgE antibodies were detected the schizophrenics had slightly more antibodies than the controls. There was an association between a possible secondary mania and the presence of IgE antibodies to wheat or rye. However, neither the schizophrenia nor the mania findings can be regarded as evidence for food allergy causing psychiatric disorder, since the immunological findings in both cases may represent consequences of the illnesses or their treatment, rather than causes of the illness.

The prevalence of thirst, subjective polyuria and related side-effects was investigated in 87 patients attending a lithium clinic and in a group of 52 controls. Thirst was surprisingly common, occurring in 67% of patients, in spite of the fact that they had been maintained on relatively low levels of lithium, and was due principally to the lithium rather than to other psychotropic drugs. Urine flow and impaired renal water absorption correlated with the serum lithium level and the length of treatment in the patients, despite the fact that few were clinically polyuric. The pattern of the results confirms previous suggestions that lithium may stimulate the thirst mechanism directly as well as via an increased renal resistance to vasopressin. The possible implications in terms of clinical response are discussed.

In normal women sedation following intravenous administration of the α2-adrenoceptor agonist clonidine (1·3 μg/kg) was significantly greater following 3 weeks' continuous treatment with the combined contraceptive pill than at the end of the 7-day withdrawal period. In contrast, sedative responses to the dopamine agonist apomorphine (5 μg/kg subcutaneously) were decreased when subjects were taking the contraceptive pill. These findings are in agreement with animal experimental studies, indicating that oestrogen can alter α-adrenoceptor and dopamine autoreceptor sensitivity. Such interactions may be involved in the effects of female sex steroids on mood.

The tests that have been used to assess glomerular and tubular function in patients receiving treatment with lithium have been reviewed. The advantages and disadvantages of these are discussed. The most useful tests are the creatinine clearance, which may be predicted from the serum creatinine using a formula or nomogram, and the measurement of urine osmolality, followed if necessary by assessment of the maximum urine concentrating ability after desamino cys-1–8-D arginine vasopressin.

Health care workers often advise patients with chronic psychiatric disability against marrying each other. A survey of a group of such marriages revealed no evidence of the predicted ill-effects, but rather a trend towards improvement after the marriage. There is a discrepancy between professional expectations and actual outcome of these marriages.
