5-HT3 receptors have an exclusive neuronal location and evidence is presented of their involvement in behaviour. 5-HT3 receptor antagonists such as ondansetron, tropisetron and zacopride have provided the critical pharmacological tools to reveal a potent and efficacious ability to regulate disturbed behaviour. Thus the 5-HT3 receptor antagonists will restore to normal rodent and primate behaviour disturbed by increasing limbic dopamine function, aversive situations, cognitive impairments and drug abuse. The remarkable feature of their action is a failure to modify normal behaviour. This unique pharmacological signature has ensured a wide interest in the potential role of the 5-HT3 receptor antagonists in the treatment of schizophrenia, anxiety, age related memory impairment and the problems of withdrawal from drugs of abuse. The preclinical data and preliminary clinical observations are presented.

Based on data from the nationwide Danish Psychiatric Case Register, trends in admission rates and treatment-day rates were studied in two Danish counties between 1977 and 1989. During the observation period, the number of available beds in the counties investigated decreased from 1.78 to 1.10 per 1000 inhabitants aged 15 years or more. Over the same period, the admission rates decreased by 20% for in-patients and 38% for day-patients. At the same time, treatment-day rates for in-patients decreased by approximately 50% and treatment-day rates for day-patients by 32%. The decrease was seen in all age groups both for admission rates and treatment-day-rates. Rates for short-term hospitalization showed a steeper decrease than those for long-term hospitalization. For schizophrenia, admission rates increased except among men under 25 years of age, and treatment-day rates decreased in all age groups. Affective disorders, neuroses, personality disorders, and alcohol and drug abuse showed the most pronounced decreases in admission rates and treatment-day rates. The same trend was seen for treatment-day rates for organic disorders. A marked decrease in admission rates was seen in the provincial towns. Treatment-day rates decreased markedly in city areas, and less so in rural areas.

Abuse of alcohol and other drugs by mental patients has been reported extensively in the past decade, especially in the USA. It has seemed to us that drug abuse has become more common among mental patients treated at this psychiatric hospital and at outpatient clinics in Jerusalem in recent years. Therefore, 100 patients admitted consecutively were questioned with regard to alcohol and drug abuse. A quarter of the male patients were diagnosed as having both a psychiatric disorder and drug abuse. Drug abuse was even more common among male schizophrenics aged 26 to 35, but only 2 reported alcohol abuse. Drugs used were mainly opiates (heroin and methadone) and hashish, and in most cases both. The results indicate that mental patients, especially young men with schizophrenia, may be another risk group for drug abuse in Israel.

The risk of suicide associated with different psychiatric diagnoses was estimated in 80,970 inpatients in Stockholm County (population 1.6 million). All patients discharged with at least one psychiatric diagnosis between 1973 and 1986 were followed by linkage with the cause-of-death registry through 1987. There were 1,115 definite suicides and 467 undetermined suicides among these during the 15-year follow-up. When 12 diagnostic categories were entered in a proportional hazards model, the highest relative risk (RR) of definite suicide, controlling for sex and age, was noted for affective disorders (RR 2.82), followed by unspecified psychoses (RR 2.69), paranoid psychoses (RR 2.60), addiction to prescription drugs (RR 2.38), neuroses and reactive psychoses (RR 1.96), and schizophrenia (RR 1.64). Alcoholism, personality disorders, organic psychoses, and street drug addiction did not have significantly increased risks of suicide. Male sex increased the risk for definite suicide by 1.56, while the risk was somewhat higher among the young. Having more than one diagnosis increased the relative risk by 1.42. When undetermined suicides were included in the analysis, to alcoholism and street drug abuse were attributed significantly increased risks of suicide, probably owing to the greater difficulty of verifying such cases. We conclude that several psychiatric disorders were conductive to suicide, but that the risk did not vary much with the type of diagnosis. Further studies of confounders are needed, such as the reasons for being admitted to inpatient care, and the impact of somatic and psychiatric comorbidity.

Heart transplant programs were surveyed regarding psychosocial evaluation process, criteria, and outcomes. There was considerable disagreement among programs when a patient is rejected on psychosocial grounds with regard to the use of second opinions and how often patients are informed of the reasons. Wide discrepancies in criteria used and rates of patients refused on psychosocial grounds were discovered. More than 70% of all programs excluded patients for transplantation on the grounds of dementia, active schizophrenia, current suicidal ideation, history of multiple suicide attempts, severe mental retardation, current heavy alcohol use, and current use of addictive drugs. Lack of consensus was found for some exclusion criteria (cigarette smoking, obesity, noncompliance, recent alcohol or drug abuse, criminality, personality disorder, mild mental retardation, controlled schizophrenia, and affective disorder). The proportion of patients rejected for transplantation on psychosocial grounds ranged from 0% to 37%, with an average rate of 5.6% in the United States and 2.5% in non-U.S. programs. This survey thus supports the need for research on the validity and reliability of psychosocial selection criteria.

In the period 1985-89, 124 physicians were hospitalized in Norwegian psychiatric institutions. 20-30 physicians are hospitalized every year. The overall rate of admission to psychiatric institutions seems to be relatively higher among other groups of the adult population than among physicians. The physicians suffer from schizophrenia less frequently than others do, and suffer more frequently from affective and other psychoses. Drug abuse is also a typical disorder among hospitalized physicians. 1/4 of the physicians were hospitalized in Modum Bads Nerve Sanatorium, and the author compares the material from this institution with that from the other 33 psychiatric institutions in Norway.

Children with conduct disorder have long been known to be at high risk for developing externalizing disorders, alcohol and drug abuse, and antisocial personality. Relationships of conduct disorder to other adult psychiatric disorders, on the other hand, have not been definitively shown. Taking advantage of the large community sample (N = 19,482) interviewed in the NIMH Epidemiologic Catchment Area Program, the authors examined the effects of childhood conduct problems on ten DSM-III psychiatric disorders: somatization, phobia, panic, obsessive-compulsive, depression, mania, alcohol use disorder, drug use disorder, schizophrenia and antisocial personality. Each of the ten adult disorders showed an increase in prevalence with an increasing number of conduct problems, although effects were stronger for externalizing disorders. The predictive power of conduct problems was similar for males and females. The effect of conduct problems on nonexternalizing disorders was found to be largely mediated through externalizing disorders, particularly for men but direct effects also occurred for both sexes. These findings raise questions about the conventional view of psychiatric disorders as divisible into externalizing and internalizing disorders. They also suggest that the increasing rates of conduct problems in younger cohorts may be responsible in part for the rising rates of other disorders. Thus, prevention of and early intervention with conduct disorder may hold promise for reducing rates of a broad range of disorders.

Gender differences in the specificity of drug versus alcohol transmission were examined among 201 opioid addicts and their 877 first-degree relatives using direct interviews and a structured family history method based on the Schedule for Affective Disorders and Schizophrenia Research Diagnostic Criteria. A strong association of parental alcoholism with alcoholism among the proband addicts was found, suggesting some specificity for drug versus alcohol abuse. We also found that among the 477 siblings, those with alcoholism alone did not have parents with drug abuse and those parents with drug abuse did not have children with alcoholism alone. Rates of parental alcoholism were higher in alcoholic female than in alcoholic male probands, suggesting greater female "loading" was needed in order to become alcoholic. This increased loading in women was also found among the siblings, but alcoholic parents appeared to transmit a nonspecific tendency for either drug or alcohol abuse to their female children. Thus, it may take a greater "dose" of parental transmission for a woman to become a substance abuser, and transmission of alcoholism may be specific in men, but not in women.

During the period 23.11.1987-22.11.1989, a total of 7,906 patients attended the psychiatric outpatient department and observation section on 12,469 occasions. Sixty patients (0.8%) behaved violently on 85 occasions. None of these episodes of violence resulted in injuries to persons requiring medical attention. 90% of the violent patients were men and 70% were in the age group 20-39 years. Approximately 1/5 were psychotic and, of these, approximately half suffered from schizophrenia. Comparison with the non-violent patient revealed that the probability of violence was greater if the patient was a man under the influence of alcohol and who had the diagnoses of narcomania, drug abuse or personality disorders. Significantly fewer violent patients were admitted than non-violent patients. Over 80% of the violent patients had previously been admitted to psychiatric departments. Approximately 60% had behaved violently on previous consultations with the psychiatric outpatient department.

To document the existence of "predatory" (goal-oriented, planned, hidden, or controlled) and "affective" (impulsive, unplanned, overt, or uncontrolled) subtypes of aggression, this study assessed 73 aggressive child and adolescent psychiatric patients for the presence of theoretically predatory and affective behaviors. Cluster analysis, using the reliable items, confirmed the predicted partition, yielding a "predatory" and an "affective" cluster. The scale, with a total score from +5 (fully predatory) to -5 (fully affective), had good internal consistency (alpha = .73). The score distribution tended to be bimodal, with peaks at -3 (predominantly affective) and 1 (mixed). Patients with "affective" aggression were more likely to have lower IQ, to receive neuroleptics or lithium, and to have a chart diagnosis of schizophrenia. History of drug abuse was more frequent among the "predatory" patients.
