Ten adult patients with psychiatric disorders in the intensive care ward were examined. The length of stay varied from one week to four months and mechanical ventilation was necessary for all patients. Their experience of intensive care and their psychosensorial problems were as follows: temperospatial disorientation, perturbation of the sense of posture, hallucinations which could go as far as oneiric delirium, anguish and symptoms of depression. No psychotic syndrome, literraly speaking, was observed objectively. In the monthes that followed the stay under intensive care many patients presented important psychosomatic disorders. Organic factors are responsible for these complications, though the environment of the intensive care could induce a marked disafferentation. An effort by the attending staff, aimed at orientating or "reafferenting" these patients, could reduce these problems.

Marijuana is widely used, yet few data concerning its actions combined with other drugs exist. Psychologic, respiratory and cardiovascular effects of delta9-tetrahydrocannabinol (THC), the active component of marijuana, combined with oxymorphone (OXM) or with pentobarbital (PBL), were studies in 15 healthy volunteers. Oxymorphone, 1.0 mg/70 kg, iv, caused sedation and ventilatory depression (minute ventilation: 24.9 plus or minus 11.9 SD to 14.1 plus or minus 4.9 1/min with PETCO2 held at 50 torr) in eight volunteers. TCH (27, 40, 60, 90, and 134 mug/kg, iv) increased sedation and further decreased ventilation with each TCH dose to 6.6 plus or minus 3.7 1/min after 134 mug/kg. The combination of OXM and THC decreased the CO2-ventilation slope from 2.23 to 0.88 1/min/torr. When THC, 134 mug/kg, was added to OXM, which alone caused no significant cardiovascular change, cardiac index (4.1 plus or minus 1.3 to 5.0 plus or minus 2.2 1/min/m-2) and heart rate (66 plus or minus 12 to 107 plus or minus 31 beats/min) significantly increased and total peripheral resistance (1,030 plus or minus 260 to 660 plus or minus 200 dynes-sec/cm-5) decreased. Heart rates exceeded 150 beats/min in two subjects after 27 and 134 mug/kg THC. Pentobarbital alone, 100 mg/70 kg, iv, caused no significant ventilatory or cardiovascular change. THC, after PBL pretreatment, induced hallucinations and anxiety in five of seven volunteers; four failed to complete all five doses of THC becuase of the severe psychologic effects. The combination of PBL and 40 to 134 mug/kg THC did not affect ventilation significantly. After PBL pretreatment, THC significantly increased heart rate (76 plus or minus 17 to 130 plus or minus 32 beats/min). Cardiac index also increased (3.8 plus or minus 0.8 to 5.6 plus or minus 1.9 1/min/m-2) and total peripheral resistance decreased (1,070 plus or minus 240 to 720 plus or minus 300 dynes-sec/cm-5). Three subjects developed heart rates esceeding 150 beats/min after 27, 27, and 90 mug/kg THC; in all three, heart rates fell from maximal value with a further dose of THC.

The authors studied the occurrence of depression in 100 randomly selected patients with narcolepsy and in 30 patients with hypersomnia. In the isolated form of idiopathic narcolepsy (without signs of cataplexy, sleep paralysis or hypnagogic hallucinations) depression occurred 28.6 per cent of cases. In idiopathic narcolepsy with cataplexy or other symptoms of sleep dissociation, depression was found in 17.2 per cent of cases. In idiopathic hypersomnia the occurrence of depression was 26.1 per cent. In the majority of cases the endogenous form of depression was observed. In the symptomatic form of narcolepsy and hypersomnia the occurence of depression has not been noted in any case. In most cases a parallel clincial course has been observed between the manifestation of depression and narcolepsy or hypersomnia. During a remission of the depressive state the hypersomniac symptoms decreased or disappeared totally. The authors furter discuss the possible pathophysiological mechanisms of the above mentioned symptoms. They are of the opinion that an important role is played by the secretion and metabolism of the cerebral monamines.

Thirthy-three alcoholics, aged between 31 and 82 years, were treated for 7 to 30 days with tiapride. The dosage was 600 mg/day (200 mg 3 times daily) by mouth or 100 to 800 mg/day I.M. Out of 27 cases of tremor treated, there were 25 favourable results, one average result and one nil result. Insomnia and character disorders, e.g. anguish, depression, nightmares, hallucinations, were improved during the first few days of treatment in 27 cases out of 30. Out of 12 cases of algo-paresthesia of the lower limb treated, the were 9 good or excellent results, 2 average results and 1 nil result. A favourable result was observed in 7 cases out of nine in vomiting, water brash (3 cases out of 4), and in 16 cases out of 20 in anorexia. No clinical or laboratory disturbance attributable to tiapride was noted in our patients whose general health was often very poor.

A total of 24 patients (20 men and 4 women) were treated for varying degrees of alcoholism. Tiapride was administered orally as 300 to 600 mg/day to 22 patients, the other two cases receiving i.v. injections followed by oral doses. Tiapride was extremely well-tolerated and no side-effects were noted. Withdrawal symptoms were effectively reduced, and a significant action was noted against tremor. Tiapride was also effective against depression and anxiety, and hallucinations disappeared in two cases.

A strategy is presented for biological psychosis research with neuroleptics acting as a point of crystallisation like antidepressants do in biological depression research. The neuroleptics chlorpromazine, haloperidol and oxypertine were studied, and it was found that they influence central catecholamine (CA) metabolism in man. An increased central dopamine (DA) turnover was found to occur in psychotic disorders, mostly in the form of motor agitation. As the first of a planned series of studies, chlorpromazine with presumed ability to reduce both DA-ergic and noradrenaline (NA)-ergic transmission and oxypertine as a more selective blocker of NA-ergic transmission were selected for comparison. The overall therapeutic effect of oxypertine was inferior to that of chlorpromazine, whereas oxypertine proved more effective in cases where loss of initiative was predominant. On the other hand, chlorpromazine exerted a more marked influence on extrapyramidal motor functions than oxypertine. In chronic psychotic disorders with inertia, oxypertine thus seems to be a neuroleptic which is strong enough to prevent exacerbation of delusions and hallucinations while at the same time increasing the level of motivation. These findings were in accordance with our predictions. The comparative study is illustrative of the practical significance of the research approach in this study: The biochemical action profile of a neuroleptic seems to be a more reliable indicator of its clinical action than does its chemical structure.

During the last four years we have used a new cardioselective beta-adrenergic blocking substance, ICI 66.082 (atenolol or Tenormin), alone or in combination with other drugs for treatment of hypertension in a total of 104 patients, including 15 with a chronic obstructive lung disease. Fifty-one patients started treatment with atenolol because of side-effects--especially from the central nervous system--during previous treatment with non-selective beta-blockers, mostly propranolol (Inderal). Mean duration of treatment was 16 months (range 8--36) and mean dosage 163 mg/day. In 18 patients treatment with Tenormin was withdrawn, but only in 10 of them could this be referred to side-effects. Of the 51 patients who complained of or showed side-effects from another beta-blocker, 80% were improved after changing to Tenormin. Of the patients with side-effects from the central nervous system, 73% improved, especially those who complained of nightmares, hallucinations, insomnia or mild depression.

We studied 779 walk-in psychiatric patients presenting to 32 first- or second-year residents and 772 patients presenting to 25 third-year residents or attending physicians as to the decision to admit to the hospital or to administer medication to those not admitted. There were no significant demographic or clinical differences between patients presenting to the two groups. The more experienced staff admitted half as many patients and treated serious depression with tricyclics twice as frequently. Inexperienced psychiatrists used hospitalization more frequently when these patients suffered from suicidal ideation, hallucinations, delusions, and inability to cope. When the training procedure was modified and second-year residents were introduced into a more structured setting, their decision-making quickly approached that of third-year residents and attending physicians. We suggest that specific training can modify decision-making, where general clinical experience may not. Implications for resident and medical student training are discussed.

This study suggests that patients receiving daily doses of 40 mg of prednisone or its equivalent, are at greater risk for developing steroid psychosis. Psychotic reactions were twice as likely to occur during the first 5 days of treatment as subsequently. Premorbid personality, history of previous psychiatric disorder, and a history of previous steroid psychosis did not clearly increase the patient's risk of developing psychotic reaction during any given course of therapy. Steroid psychoses present as spectrum psychoses with symptoms ranging from affective through schizophreniform to those of an organic brain syndrome. No characteristic stable presentation was observed in these 14 cases reported here. The most prominent symptom constellation to appear some time during the course of the illness consisted of emotional lability, anxiety, distractibility, pressured speech, sensory flooding, insomnia, depression, perplexity, agitation, auditory and visual hallucinations, intermittent memory impairment, mutism, disturbances of body image, delusions, apathy, and hypomania. Phenothiazines administered in average daily doses of 212 mg produced excellent response in all patients studied. Of particular note was the fact that tricyclic antidepressants produced an exacerbation or worsening of the clinical state in all patients to whom they were administered.

A simple manifestation of the memorial processes is the so called reversed postoptokinetic nystagmus (RPN), a trace phenomenon elicited in the rabbit by prolonged (60 min) optokinetic (OK) stimulation. Electrophysiological analysis of RPN indicated that the underlying neural trace is weakened, but not suppressed by spreading depression in the cerebral cortex or superior colliculus. An asymmetry of RPN is brought about by unilateral 6-OHDA lesion on substantia nigra. Electroconvulsive shock applied immediately after a period of OK stimulation blocks the subsequent RPN without interfering with OKN. About 70 percent of neurons in the vestibular complex changed their activity during OKN and RPK. The changes consisted in most cases of an excitation accompanying OKN and inhibition during RPN. The OKN-RPN related reacti6ns were also abundant in flocculus but significant activity changes during RPN were less frequent in this structure. Units in midbrain reticular formation reacted both during OKN and RPN in a similar fashion as the vestibular ones. On the other hand units in the cerebellar deep nuclei and brachium conjunctivum were only weakly influenced by OKN and/or RPN. It is suggested that the neural trace of RPN develops in the vestibular complex and vestibulocerebellum as a part of the process compensating the effect of continued optokinetic stimulation. Flocculus participates in input processing of the optokinetic stimulation whereas reticular formation mediates signal transmission to oculomotor and higher integrating centers. The trace, revealed by sudden cessation of the eliciting stimulus in absence of visual reference signals is probably the neural substrate of the so called motion habituation and visual hallucinations. As other compensatory phenomena in the motor system, RPN has features of instrumental (it improves the organisms control of environment) and classical (it is automatically established and involuntarily emitted) conditioning.
