Suicide is intentional self-killing, and parasuicide an act of deliberate self-harm—either by injury, ingestion or inhalation—not resulting in death (Black et al, 1982). Both are rare under the age of 12 and the rate of suicide in those under 16 remains consistently low. Referrals to psychiatric services reported by Shaffer (1974) indicated that 7–10% were for threatened or attempted suicide, while Hawton (1982) quoted studies giving the incidence as 10–33% for children aged six to 12; in England and Wales (1962–1968), suicide accounted for 0.6% of deaths in the 10–14 age-range. McClure (1984) found that between 1975 and 1980, only ten such deaths were recorded in the 13-and-under range, and 26 deaths in the 14 year-olds, after which the number of suicides rose sharply with each successive year. That study also showed that parasuicide was most common in the 15–24 age-group, but at younger ages there was a higher proportion of undetermined deaths, as against officially recorded suicides. The social taboos associated with suicide may lead to its systematic under-reporting, but even allowing for that, the phenomenon is still a rare one under the age of 16.

A follow-up study of all patients entering the MRC double-blind trial of fluphenazine decanoate in chronic schizophrenic out-patients achieved a trace rate of 94%. In general, these patients were severely disabled, continued under the care of the maintenance clinic, and their diagnoses remained remarkably consistent; more than one-fifth were found to be in acute schizophrenic relapse and in over a half of these cases, the relapse was not known to the treatment agency. The maintenance clinic attenders were little different from those who no longer used such a facility.

Seven years after the completion of the original trial, over 73% of patients were maintained on depot neuroleptics, and 70% had received such medication for over seven years. About 40% had presented with a problem of compliance at some time, and there was a significant correlation between poor compliance and in-patient admissions and schizophrenic relapses. The prevalence of parkinsonian side-effects, akathisia, and tardive dyskinesia was low. Non-psychotic symptoms were common, even in the absence of acute psychosis. Depression was found in a subgroup of patients; it was frequently reported as an indication for admission during follow-up period, and seemed to be part of the schizophrenic illness rather than a result of antipsychotic drug treatment.

The relapse and admission histories revealed a positive correlation between number of schizophrenic episodes and time on maintenance medication, probably reflecting severity of illness. Relapse rates after drug discontinuation rose to 45% within 13 months. There were no differences of predictive value between those relapsing on or off medication. The relationship between relapse rates, drug treatment, and social outcome is complex; antipsychotic drugs may postpone relapse, and frequent relapses might inhibit improvement in social performance long after florid symptoms have been controlled by medication.

Marked differences were found between the reasons chosen to explain overdoses by the closest relatives or friends (the ‘significant others’) of 34 self-poisoners and those reasons chosen by the self-poisoners themselves. Whilst 41% of the latter claimed suicidal intent, in only one case was the significant other in agreement. The significant others were more likely to attribute manipulative reasons, commonly viewing the overdoses as directed at themselves, but the two groups agreed that the overdoses were often a means of alleviating distress. As well as evoking sympathy, the overdoses often caused the significant others to feel considerable guilt and anger. Discrepancies in the way self-poisoners and significant others interpret overdoses, and the strong feelings that overdoses evoke in the latter, should be considered during assessment and treatment of overdose patients.

The association between parental attempted suicide and child abuse was investigated in 114 mothers with children aged five years and under, referred to a general hospital following suicide attempts. The risk was greatly increased in the attempted suicide mothers, compared with both similar mothers at risk for depression and general population control mothers; well-documented risk of child abuse was identified in 29.8% of those who attempted suicide. No major differences were found between the attempted suicide mothers whose children were at risk and those whose children were not at risk. During the general hospital assessment of mothers with young children who attempt suicide, careful enquiry concerning the relationship with the children is essential

Both mates of schizophrenic mothers and a control group consisting of mates of non-schizophrenic mothers were diagnostically examined. The former were more frequently psychiatrically deviant than their controls, both with respect to a life-time syndrome diagnosis and a personality diagnosis. Mating between a schizophrenic mother and a father who suffered from schizophrenia spectrum disorder significantly increased the offspring's risk of developing a schizophrenia spectrum disorder himself. Assortative mating was negatively correlated with age of onset of maternal schizophrenia. It is proposed that defective emotional rapport or sub-psychotic features constitute the phenotypic traits by which assortative mating operates in schizophrenia.

Plasma Cortisol levels were elevated in a large proportion of samples from manic patients. Although a correlation was found between clinical ratings of the severity of mania and the degree of elevation of daytime Cortisol levels, some patients with low clinical ratings had elevated Cortisol levels. During treatment with haloperidol, Cortisol levels returned to normal earlier that the clinical state. The underlying mechanisms are discussed.

Cerebrospinal fluid (CSF) from 20 chronically hospitalised male schizophrenics and from 12 patients admitted with acute schizophrenia were examined for antibodies against cytomegalovirus. A sensitive and specific enzyme-immunoassay was used to detect IgG or I g M classes of antibodies in the CSF of the schizophrenic patients and often orthopaedic patients, who served as controls. No significant amounts of I g M antibody were found in the CSF of either group. A significant titre of IgG was found in only one of the 32 schizophrenics, an acute patient, but in four of the orthopaedic patients. The results do not support an association of cytomegalovirus infection with schizophrenia; if such an association occurs, it must be unusual.

Opioid receptor binding sites were assessed in membrane preparations of caudate nucleus from post-mortem brains of controls and of patients with schizophrenia. There was no difference between the two groups in the total specific binding of 3H-etorphine or in its ‘μ’ and (‘δ+χ’) components. Similarly, the binding of 3H-naloxone did not differ between patients and controls. It is concluded that a previous report of reduced opioid receptors in caudate of schizophrenics is unlikely to prove a consistent finding and that the results of the present study offer no support to the claim that there is a general disturbance in opiate mechanisms in schizophrenia.

Renal function test results in 26 patients on neuroleptic treatment, who had never received lithium or antidepressants, were compared with those in a matched group, treated with lithium; also, their tubular response to DDAVP was compared with that of 25 control subjects. Measurements of serum creatinine, creatinine clearance, and urinary albumin excretion showed no abnormality attributable to either neuroleptics or lithium. The maximum urine concentrating ability after DDAVP was significantly lower in the neuroleptic group than in controls, but significantly higher than in the lithium-treated patients. There was a significant correlation between excretion of urinary ß2-microglobulin and duration of neuroleptic treatment, but mean excretion rates were the same in both treatment groups. The results suggest that neuroleptics as well as lithium impair urine concentrating ability.

To investigate the effectiveness of a new benzodiazepine, alprazolam, and to compare this with amitriptyline (AMT) and with placebo, a trial was undertaken in 65 patients in whom depression was considered to be the dominating feature but not considered to be the primary cause of their condition; it was designed to exclude endogenous depressions. A consistent pattern was found favouring alprazolam over AMT both in rate of response and in total response, as well as significant differences in favour of both alprazolam and AMT over placebo. A comparison of side effects showed a definite trend in favour of alprazolam and placebo over AMT.

Sixty nine patients took part in a double-blind study to investigate the efficacy of bilateral, unilateral, and simulated ECT in the treatment of depressive illness. The findings suggest that both bilateral and unilateral ECT are highly effective treatments for depression and are significantly superior to simulated ECT. There was also evidence that patients receiving bilateral ECT recovered more rapidly than those receiving unilateral ECT and required significantly fewer treatments. The relevance of these findings to clinical practice is discussed.

The efficacy of intramuscular pipothiazine palmitate (PP) in the management of aggressive mentally handicapped patients was examined in a double-blind, placebo-controlled, cross-over study, in which 30 patients received each treatment for 13 weeks. A target symptom scale of aggressiveness (TSA) and a clinical global impression scale of efficacy were rated at monthly intervals, and an extra-pyramidal side-effects scale weekly. The patients showed marked improvement during treatment with PP, which was assessed as superior to placebo. Individual and total TSA scores were also reduced compared to placebo.

One hundred and fifty anxiety neurotic and neurotic depressive twin probands were differentiated into three groups by means of discriminant analysis, 50 in each group. The groups were named: pure anxiety neurosis, mixed anxiety-depression, and pure neurotic depression. Analysis of concordance rates indicated that only pure anxiety neurosis seemed to be influenced by hereditary factors.

Psychomotor retardation is important in some depressed patients. We found that speech pause time (SPT) during a counting test correlated with the reaction time of both depressed patients and controls. It also correlated with global psychomotor retardation measured on Widlocher's scale. We demonstrated increased SPT in unipolar depressives, and also in retarded depressives as a group when compared with controls and with non-retarded depressives. SPT varied diurnally in controls, but not in depressed subjects. It did not correlate with biological markers of depression (REM sleep latency and the dexamethasone suppression test). It did, however, shorten during clinical improvement with antidepressant chemotherapy.

Unusually frequent sinistral motor and sighting dominance have sometimes been reported in schizophrenics, although the majority of patients are still dextral. In this study, assessment of lateral dominance also included a measure of grip strength—a potentially more sensitive index of dominance or lateralised impairment; schizophrenics, non-schizophrenic patients (affective disorder), and normal controls were studied. There were no differences in handedness or sighting dominance. Affective patients, particularly bipolar psychotics, had greater right-handed grip superiority than normals or non-paranoid schizophrenics. Paranoid schizophrenics were similar, being significantly greater in right-sided dominance than non-paranoids, who tended toward a smaller value than normals. Hand grip asymmetry was highly correlated with handedness in normals, but not in patients. The possibility is discussed that these results may reflect asymmetrical patterns of cerebral impairment or attentional bias.

The case of a 17 year-old female with psychogenic polydipsia is reported; 13 out of 18 members of her maternal family were known to have had polydipsia and polyuria, but only two had undergone endocrine investigations—one had diabetes insipidus and one also had psychogenic polydipsia. There are probable contributions of non-genetic family factors including imitation and identification to the development of this patient's condition. Detailed family and developmental histories may be of particular assistance in the understanding of the psychogenesis of the disorder in some patients.

An unusual case of Huntington's Chorea, without dementia, is described. The diagnostic issues are discussed with particular reference to the problems of psychiatric assessment and management of the disease.

We report two cases showing psychiatric symptoms associated with a fear of Acquired Immune Deficiency Syndrome (AIDS). There have now been over 42 cases of AIDS in the United Kingdom (Communicable Disease Surveillance Centre, 1984) since the first case appeared in December 1981, a year after the syndrome was first identified in the United States of America. It was the BBC television programme “Death in the Village” which brought the risks home to many UK homosexual men in mid-1983. Following the programme, the London Gay Switchboard received a high level of telephone calls from men who were afraid that they had AIDS (London Gay Switchboard, 1984).
