There is an increasing occurrence of drug-intoxications in infancy, thus psychopathological changes due to intoxication also occur more frequently in children. 6 children were described with cases of acute and reversible toxic psychoses whose--mainly visual--hallucinations together with conditions of excitation and hyperactivity were the most striking features of the psychopathological picture; in contrast to the more frequent delirious confusion (delirium) disturbances of consciousness and orientation were missing. The phenomenological characteristics of halucinosis in children-a condition so far not specified in the case of infants and children-have been elaborated with regard to other psychotic phenomena during infancy and adult age. Relevant neurophysiological and psychodevelopmental findings lead to the following four theorems: 1. Drugs with hallucinotic effects facilitate the occurrence of "internal" pictures independent of external perceptions which are described phenomenologically as hallucinations. This theory is based on the fact that hallucinogenic drugs intensify the electrical potentials which are evoked by optic stimulation in the visual area, while an intracortical impulse propagation is inhibited. 2. A change in emotion either caused by situation or by exogenous or endogenous factors facilitates the development of hallucinations, especially if emotions dominate to such a degree that rational control of reality is being suppressed. Since hallucinogenic drugs exert their effects not only on the sensory system but also on brain structures which influence directly or indirectly emotional functions, hallucinations might also be evoked via this mechanism. 3. Brain stem has-apart from its importance in emotional processes-a filter effect and a controlling function of sensoric stimuli originating in the periphery. Hallucinogenic drugs can influence this screening function and have a disinhibitory effect which cause an inundation of the brain cortex by sensoric stimuli which again facilitate hallucinations. 4. The neurophysiological actions discussed above which are caused by intoxications have a synergistic effect together with the psycho-developmental facts relevant to infancy. This synergism can explain the frequent occurrence of fever hallucinoses as well as the fact that agents primarily not hallucinogenic as e.g. benzydamine can also cause hallucinations in infancy.

Transient psychotic episodes may result from continuous cerebral epileptiform discharges unaccompanied by clinically observed seizures. Such episodes may mimic depressive, hysterical and schizophrenic psychosis and delirium. I describe two patients here and review eight patient histories from the literature. Diagnosis is established by use of electroencephalography during the psychotic episode. Correct diagnosis is essential because specific treatment is available and additional episodes may be prevented by appropriate long-term anticonvulsant therapy.

A melancholic-schizophrenic mixed psychosis is described in a 64-year-old man. It was diagnosed as a 'rigid (or catatonic) involutional depression' (Medow, 1922), showing besides hypochondriacal, nihilistic and micromanic delusions, a transient delusional syndrome of 'Delirium metabolicum' (Mendel, 1902), with zo-anthropy. An attempt was made to avoid the differential diagnostic classification of that clinical picture into involutional melancholia (296.0) and paranoid psychosis of involutional age (197.1) which, as in so many psychoses of the older age groups, is quite inadequate. Thus the psychopathological phenomena of the psychosis, which after all are the only reliable data, were attributed on the one hand to the senile deterioration and slight but demonstrable arteriosclerosis of the brain, and on the other hand, to the conspicuous premorbid characteristics which correspond to an anankastic psychopathy with a depressive-inadequate basic mood. It was considered as likely that the Delirium metabolicum represented an exogenous (organic) psychotic syndrome, and that the precipitation of the psychosis as well as its development into an enfeebled endstate was due to an organic brain lesion, while the catatoniformpsychomotor phenomena and the melancholic stupor were crystalisations of traits in the premorbid personality.

The gas and electrolyte homeostatic changes in arterialized capillary blood were studied in 51 patients with acute alcoholic psychosis. In 29 patients the blood and fluid data were correlated. It was established that acute alcohol delirium is mostly accompanied by alkalosis of metabolic, respiratory, or mixed origin. Irrespective of the approximate uniformity of blood and fluid changes, there is a distinctly expressed imbalance between the different parameters. After subsidence of psychotic symptoms (7-10 days after admittance) fluid acid-base fluctuations were to some extent still observable. They manifested greater resistance in comparison with blood.

Despite the development of psychopharmaceutical therapy, post partum delirium was difficult to treat. The patients remained psychotic for long periods and the course was of the disease capricious due to the many relapses. A comparative study of two groups, one consisting of 6 patients and the other of 13, all with a typical post partum delirium was carried out. The symptomatic treatment of this syndrome with a combination of perfenazine and lithium carbonate produced relatively favorable results in our clinic. For the time being, at any rate, it seems to be the medication of choice.

During the fiscal year 1 April 1972 to 31 March 1973, 22,210 ECT treatments in 3,438 series were given in Denmark (6-46 treatments per series). Indications for treatment were: endogenous depression, acute delirium, mania, hysterical psychosis, reactive depression and schizophrenia. Unilateral ECT was used in more than half of the departments concerned. Two treatments were given weekly. The types of apparatus and anaesthesia techniques used are described. One death, which had questionable relation to the ECT, was reported, and other complications were few and mild. The advantages of ECT compared to tricyclic antidepressants are described, including the higher percentage of remissions or improvements in the treatment of endogenous depressions (about 80 per cent for ECT compared to about 60 per cent for tricyclic antidepressants). Little risk was found in out-patient administration of ECT. With present techniques and unilateral placement of electrodes out-patient ECT may be recommended for wider use than before.

Long before the era of heart surgery began, "cardiac psychoses" were known and described. They do not differ at all from postoperative psychoses after heart-surgery. On the other hand heart-surgery carries a far higher incidence of psychiatric complications than general surgery (general surgery 0,1--1,0%; heart surgery 10--60%). There is no reason to believe that the intensive care unit plays a decisive role in the origin of postoperative cardiac psychoses. Among 150 patients there were 60=40%, who did not show any psychiatric symptoms after surgery. These were exposed to the same environment of the intensive care unit as were the patients who developped symptoms. There were however correlations of statistical significance between "cardiac psychoses" and 1. an occurrence of endogenous psychoses in the family with first degree relatives or in the life history of the patient himself, 2 higher grade of severity of heart disease, 3. extra corporal circulation, 4. higher age, 5. male sex. Postoperative cardiac psychoses are mainly of the type of exogenous psychoses (akuter exogener Reaktionstyp Bonhoeffer). There is no doubt that psychological, reactive and environmental factors do play a certain role too. This is shown by the character of delusions and hallucinations which frequently reflect the postoperative situation. Persecutory delusions with the fear of being killed and ideas and fears of severe body mutilation are the most common motives. Similar motives are frequently observed in postoperative dreams. The manifestations of mental disease in the family or personal history of the patient is considered a significant presupposition of developing a cardiac psychosis of the type of endogenous depression, acute delirium or with schizophrenia like delusions.

The author examined 20 patients with severe brain damage. Under the influence of hyperbaric oxygen therapy there was a more rapid restitution of consciousness and a relatively short development of soporous and comatose conditions. Disoders of the Korsakoff syndrome type in such conditions had an abortive development as well (4--7 days). In cases of developing delirious states the use of hyperbaric oxygen therapy demonstrated a clearing of consciousness and a disappearance of psychotic disturbances, already following the first session.

Medication with anticholinergic properties are used commonly in family practice. Toxic delirium, which may resemble an acute psychosis, can occur as an adverse drug reaction to properly prescribed anticholingeric medication and to recommended doses of many patent medicines. More frequently it is due to overdosage. The key to diagnosis is the presence of peripheral signs of parasympathetic blockade. Delirium induced by anticholinergic drugs can be treated rapidly and effectively with physostigmine salicylate.

A study was made of burns patients who were referred for psychiatric problems. There were a total of 69 subjects, divided into three groups. The first group comprised thirty-four cases who attempted suicide by burning themselves--there were more women than men, the majority were less than forty years, and Indians were overrepresented. The majority of these were suffering from schizophrenia or a major depressive disorder. The second group of twenty-three patients were those who had a non-psychotic psychological reaction to their burns. The majority were also less than 40 years of age, and the main reactions were anxiety neurosis or reactive depression. The third group of twelve patients were suffering from delirium. All were pyrexic and in eleven, infective agents were cultured. Some of them also had electrolyte abnormalities and two had respiratory burns.
