A lower incidence of attempted suicide was found for Oxford University students than for other persons of the same age in Oxford City. This may be due to social class differences. Characteristics of the student attempters are reported. On the other hand, the rates for completed suicides of students, over a recent ten-year period, were in excess of those for the rest of their age group.
In a six-month study of psychiatric hospital in-patients, it was found that accidents more often occurred among females and among patients on psychogeriatric wards. Falls were the most common form of accident. Accidents resulting from the aggressive behaviour of other patients usually occurred on long-stay and rehabilitation wards, with middle-aged patients the victims.
Several surveys have confirmed that the majority of patients who take an overdose of drugs have seen their general practitioner within the preceding few weeks; as many as a third attend within the previous week.We studied 130 patients who had taken an overdose and interviewed 122 of the general practitioners. We found that they had identified many interpersonal problems and had usually prescribed psychotropic drugs.We question the wisdom of this response and suggest other ways of handling such problems in general practice.

A sample of individuals who had carried out acts of self-poisoning or self-injury were interviewed and information was also obtained from their general practitioners. More of both the men and the women had visited their general practitioners in the year before the acts than would have been predicted from national statistics, although this was not found to the same extent for persons aged 16-24. Thirty-six per cent of the sample had contacted their general practitioners during the week before the act and over 60% in the month beforehand. Sixty-three per cent had visited them for a variety of psychiatric and social reasons during the preceding year and had nearly all been prescribed psychotropic drugs, usually tranquillizers or sedatives. These were commonly the drugs taken in acts of self-poisoning. Methods of prevention are discussed.

OBJECTIVE: To determine whether patients with "pure" chronic fatigue syndrome (neurasthenia) have sleep abnormalities which may contribute to subjective measures of daytime fatigue. METHOD: Sleep characteristics of 20 patients meeting research criteria for chronic fatigue syndrome (CFS) but not depression, anxiety, or sleep disorder were compared with sleep characteristics of 20 healthy subjects matched for age and sex. Measures of sleep included a) subjective interview reports and sleep diaries and b) home-based polysomnography. RESULTS: Patients with CFS complained of poor quality unrefreshing sleep. They also napped during the day. Polysomnograph data showed no difference in actual nocturnal sleep time between the two groups although patients with CFS spent significantly longer in bed (p < .01), slept less efficiently (p < .03), and spent longer awake after sleep onset (p < .05). The polysomnographs of seven patients with CFS and one healthy subject were regarded as significantly abnormal. Five patients and one healthy subject had difficulty maintaining sleep. One patient had a disorder of both initiating and maintaining sleep and one patient woke early. CONCLUSIONS: Patients with "pure" CFS complain of unrefreshing sleep but only a minority have a clearly abnormal polysomnograph. The most common abnormality is of long periods spent awake after initial sleep onset. Although sleep abnormalities may play a role in the etiology of CFS, they seem to be unlikely to be an important cause of daytime fatigue in the majority of patients. However, pharmacological and behavioral methods that improve sleep quality may be an important component of a pragmatically based treatment package for patients who do have abnormal sleep.
