Mortality was determined in 519 patients with delirium who were seen in psychiatric consultation in two general hospitals. Among 419 patients with simple delirium (DSM-III: 293.00) in-hospital mortality was 26%. As compared to average hospital patients the age adjusted in-hospital excess mortality ratio varied from 6.2 for patients with malignancies to 2.1 for patients with motor system disease. ⋯ As compared to the general population excess mortality was noted in most, but not in all diagnostic subgroups. The age and sex adjusted excess mortality ratio varied from 14.1 for malignancies to 1.3 for motor system disease. The figures underline a general notion that delirium may be an indicator of disorders of grave prognosis, but mortality appears to depend more on the medical condition than on the presence of delirium.

We compared symptomatic, hemodynamic and opioid responses of heart disease patients to exercise testing and a stressful public speaking task. Plasma beta-endorphins were measured at rest and immediately post stress. Nineteen of 50 patients had angina during exercise; 31 had asymptomatic ischemia. No patient had angina during the speech, but two had ECG changes and 39% had radionuclide changes indicating ischemia. Patients with asymptomatic ischemia on exercise had a significantly greater beta-endorphin response than those with angina. Public speaking elicited a significantly larger beta-endorphin increase relative to change in double product (an index of stress) than did exercise. ⋯ (1) Patients with silent vs painful ischemia experience a greater beta-endorphin response to exercise. (2) beta-endorphin response to a speech stressor is greater than to exercise when controlled for an index of stress. (3) Increased beta-endorphin response to a speech stressor may partially explain the predominance of silent ischemia during psychological stress.

Randomized Controlled Trial Clinical Trial
The physiological stress response and the role of cognitive coping in migraine patients and non-headache controls.
Our study investigated physiological response specificity and cognitive coping in migrainous patients during an achievement task situation. Thirty-three migrainous subjects and thirty-two non-headache controls were subjected to 40 min of demanding cognitive tasks and 20 min of recovery during which cranial and peripheral vasomotor responses were registered as well as electrodermal and myographic activity. Subjects of both groups were randomly assigned to two experimental conditions, a so-called 'spontaneous processing condition' and the 'positive coping treatment'. ⋯ The hypothesis that the predicted cranial vasomotor specificity in migraine subjects correlates with negative cognitive coping habits in migraine subjects best revealed in the 'spontaneous processing' condition, was not corroborated. The treatment variation regarding coping produced somewhat paradoxical effects, more relaxed and positive self-evaluation (subjective level) and more arousal (physiological level). Results are discussed for their impact on the psycho-biological model of migraine.

Sleep and fatigue characteristics were evaluated in 72 patients who met major criteria for the chronic fatigue syndrome (CFS), 57 multiple sclerosis (MS) patients preselected for fatigue complaints, and 40 healthy controls. Using previously validated rating scales, CFS patients had significant elevations in fatigue and sleep disturbance compared to the MS and healthy control groups. ⋯ Their sleep disorders included periodic movement disorder (4), excessive daytime sleepiness (3), apnea (2), and narcolepsy (1). We conclude that subjective sleep disturbance is common in CFS and some CFS patients may have objective sleep disorders.

Psychological state, response to pain and style of interpreting everyday experiences were measured in 32 patients who had suffered a whiplash injury 1-84 months before the study. For comparison, measures were also obtained in 15 general practice attenders. Ratings of depression and anxiety were greater in patients than in controls, and patients reported more cold-induced pain during a cold pressor test. ⋯ The findings demonstrate that, like most patients with chronic pain, whiplash injury sufferers are anxious and depressed. Their psychological distress could be aggravated by litigation. Behavioural assessment and treatment of chronic pain syndromes such as whiplash injury could benefit from early evaluation of the patient's psychological state, and response to standard painful stimuli.
