Oral administration of ET-495 was found to cause worsening of psychiatric status in 4 out of 7 schizophrenic patients, and to induce a paranoid state and a syndrome of auditory hallucinosis in 2 non-schizophrenics. These observations were compatible with the hypothesized role of dopamine in schizophrenia. However, these psychotogenic effects were far less dramatic than those noted in other studies with amphetamine, methylphenidate or L-Dopa. Possible explanations for this differing psychotogenic potency of receptor stimulators versus presynaptic agonists are presented. Intravenous ET-495 and apomorphine did not show psychotogenic effects.

The total number of adults with Down's syndrome living in Leicestershire, ascertained by widespread enquiry, was found to be 378. Of these, 371 were matched with adults with mental handicap due to other pathologies, on the basis of age, sex, and type of residence. Those with Down's syndrome were found to have a different spectrum of mental disorders from those without the syndrome. In particular, Down's syndrome patients were more likely to have been diagnosed as having depression and dementia; the controls were more likely to have been diagnosed as suffering from conduct disorder, personality disorder, or schizophrenia/paranoid state. The same proportion of each group had been given a diagnosis of autism.

Sera from psychiatric patients (32 with senile dementia, 56 with Alzheimer's disease, 189 with schizophrenia, 117 with manic-depressive psychoses, 52 with other nonorganic psychoses, 44 with paranoid state, 58 with neurotic depression and 78 with alcoholic syndrome), normal subjects (112 blood donors) and 43 hospitalized elderly patients with chronic cardiac failures without senile syndrome were examined by means of an enzyme-linked immunosorbent assay (ELISA) for the presence of autoantibodies to human brain S100 protein, neuron specific enolase (NSE) and myelin basic protein (MBP). These varied antibrain autoantibodies occurred at different frequencies. The highest incidence of anti-S100 and anti-NSE antibodies was in Alzheimer's disease and senile dementia, than in manic-depressive and other nonorganic psychoses, and the lowest in paranoid state, neurotic depression, schizophrenia and alcoholic syndrome. The frequency of anti-S100 autoantibodies was higher than that of anti-NSE. Autoantibodies reacting with MBP were revealed in a very small number of psychiatric patients. In healthy individuals and control cardiac patients, the incidence of antibrain autoantibodies was low. These results suggest a differential correlation between antibrain autoantibodies and psychiatric diseases.

Schizophrenia is a chronic mental illness usually considered as one of the most disabling. Its clinical manifestations are characterized by a mental splitting which is a loss of the unity and cohesion of mental activity. A paranoid state or psychomotor disturbance are, sometimes, associated with this mental splitting. The course of the disease may be continuous or oscillating with acute exacerbations. The outcome of schizophrenia is often characterized by a chronic defect state but may be quite good for one half of the patients.

First admission rates to the psychiatric hospital in Kuwait revealed that foreign housemaids as a whole had about five times the rate of Kuwaiti females. According to hospital diagnoses the housemaids had significantly more acute situational disturbances and mania, and less depressive illness and organic mental disorders. Regarding schizophrenia and paranoid state there was no significant difference between the two groups. It is recommended that good interpreters should be appointed as part of an appropriate staffing of the psychiatric hospital.

In this updating review of research on cannabis particular attention has been paid to the increasing number of studies of the disposition of the components of cannabis in man, as well as possible effects on health. Specific binding sites for cannaboids have not been demonstrated. Approximately 80 metabolites of tetrahydrocannabiol (THC) have been discovered, of which 11-OH-THC is the main metabolite, but it contributes little to the overall effect when the drug is smoked or given intravenously. The minimum plasma level of THC associated with the psychotropic effect is 25 ng/ml. Cannabis may produce directly an acute panic reaction, a toxic delirium, and acute paranoid state, or acute mania. Cannabis use may aggrevate schizophrenia, but it is much less certain whether it can lead to sociopathy or even to "amotivational syndrome". Despite widespread use of cannabis in virtually all parts of the world, no catastrophic effects on health have been noted. Cannabis appears to be relatively safe as compared with current social drugs. It is, however, still too early in the history of the present episode of cannabis use to be sanguine about possible bad effects.

Between 1936 and 1950, detailed abstracts were prepared on all patients admitted to The Phipps Psychiatric Clinic from its opening in 1913 through 1950. Of these abstracts, 74% contained follow-up reports. Except for four papers on schizophrenia and affective disorders published between 1939 and 1943, none of this material has ever been analyzed. The present paper, the first of a series, examines the 8172 first admissions from 1913 through 1940, the period of Adolf Meyer's tenure as Clinic Director. Based on discharge diagnoses, we have sorted the patients into eight diagnostic groups with the following frequencies; schizophrenia, 17%; paranoid state, 3%; manic-depressive, 7%; depression, 27%; organic, 20%; neuroses, 15%; substance abuse, 6%; psychopath, 5%. Our manic-depressive group contains cases discharged primarily as hyperthymergasia, mania, or manic depressive insanity (MDI). Of the 349 cases diagnosed MDI at discharge, 10 had neither a history of nor present symptoms of mania, and these were put in the depression group. Frequencies for most of the diagnoses remained remarkably stable over the 28-year period. Only 9% were discharged recovered, whereas 43% were rated unimproved. Mean length of hospitalization was 76 days, with 10% of the patients readmitted. The mean length of follow-up was 9 years. Correlations of diagnoses, year of admission, length of stay, condition at discharge, age, sex, readmissions, change of diagnoses, somatic treatment, length of follow-up, and deaths in the clinic are presented. Meyer's influence on diagnostic practice is discussed.

A classification of chronic psychoses including nonparanoid schizophrenia, paranoid schizophrenia, paranoid state and paranoia (delusional disorder) is presented. This classification is dependent on a systematic increase in number of symptoms with each group. In particular, delusional disorder is examined with regard to family history. It is clear from the data which are presented that delusional disorder is more likely to be associated with a family history of such traits as suspiciousness, jealousy, secretiveness, and the presence of paranoid behavior or delusions. There is evidence that such familial traits are not seen in schizophrenia, only in delusional disorder.

The treated one-year prevalence and point-prevalence of schizophrenia, schizoaffective psychosis, and paranoid state in the city of Salford were derived from the Salford Psychiatric Case Register. The high rates found are attributed primarily to the effects of selective migration from the area. A breakdown of the use of health services in the area by patients with these diagnoses is given; hospital care was found to be the major form of treatment.

The files of 283 hospitalized patients discharged with a diagnosis of schizophrenia, schizoaffective schizophrenia, or paranoid state were examined without knowledge of the patient's subsequent history. These patients, most of whom had originally been diagnosed by DSM-I criteria, were retrospectively diagnosed by New York Research Diagnostic Criteria (RDC), the New Have Schizophrenia Index (NHSI), the St. Louis criteria, Taylor-Abrams 1978 criteria, Schneider's first-rank symptoms (FRS), the Washington IPSS 12-Point Flexible System, Astrup's process/nonprocess distinction, and DSM-III. Kappa values measuring pairwise diagnostic agreement amont the nine systems were typically low except among RDC, DSM-III, and St. Louis criteria. Long-term followup status was not significantly predicted by the FRS, NHSI, or Taylor-Abrams criteria. Diagnosis by means of the other systems, especially the Astrup process/nonprocess distinction, was significantly correlated with followup. However, Astrup's "process" schizophrenia is not operationally defined and could not be expected to be used with the degree of interrater reliability desired by researchers. On the other hand, of the operationally defined systems, DSM-III schizophrenia has the highest correlation with followup and is thus suggested for use by researchers desiring a highly homogeneous, although narrowly defined, population. Investigators wishing to cast a wider net could use a less restrictive system such as the RDC, with or without schizoaffectives included.
