RESUMEN
It has been shown that an excess of pregnancy and birth complications (PBCs) does not contribute to the excess rates of schizophrenia reported for the population of Caribbean origin in Britain compared with the native Caucasian British population. We therefore attempted to compare the rate of PBCs between a sample of schizophrenics in Britain with that of a sample from Trinidad where some of the Caribbean migrants to Britain originated. First contact patients with schizophrenia according to the CATEGO system diagnosis were identified in Trinidad and London. Their mothers, where available, were interviewed using the Lewis-Murray scale for pregnancy and birth complications. Data from Trinidad and Tobago concerning 56 patients were compared with those of the Caucasian (n = 61) and African-Caribbean (n = 50) patients in London. The rate of PBCs was similar for the Caucasian British patients (24.6%) and the patients in Trinidad and Tobago (21.7%). The rates were lowest in the African-Caribbean patients in London (14.0%), though this difference was not statistically significant. These findings suggest that pregnancy and birth complications are a risk factor for a substantial minority of patients with schizophrenia in Trinidad and London. It also confirms that the excess rates of schizophrenia reported for the Caribbean population in Britain are not due to these complications.

OBJECTIVE: Sociodemographic factors play an important role in the genesis of mental disorders. High rates of unemployment and other social factors have been reported previously among African-Caribbeans with schizophrenia in London. The aim of the present study was to compare these factors in Trinidad with London African-Caribbeans. METHOD: Using internationally defined criteria, patients with first-onset schizophrenia were recruited in both countries, and information on the onset of symptoms, help-seeking, pathways into care, premorbid personality and educational and employment status were collected. These two samples are compared on a number of these factors. A total of 56 cases of first onset of psychosis coming into contact with psychiatric services in Trinidad were studied. Of these, 46 cases were diagnosed as having schizophrenia using the CATEGO program. Over a period of 2 years, 38 African-Caribbean patients with schizophrenia were recruited in London. RESULTS: African-Caribbean patients with schizophrenia in London were more likely to be admitted for perceived threat to others and to have shown loss of interest and serious neglect and to have assaulted others. A lower proportion were admitted via a psychiatrist and a higher proportion by the police. The unemployment rate among the London sample of African-Caribbeans was much higher than that in the general population, whereas this was not the case for the Trinidad patients. CONCLUSION: These findings are discussed in the context of culture and aetiology of schizophrenia, and suggestions with regard to future research are made.

Perceptions about mental illness among medical practitioners are likely to determine their capacity to recognise, treat appropriately and refer patients who have mental health problems. It is therefore important that training of medical students in psychiatry is undertaken with knowledge of their attitudes to mental health disorders. We determined the perceptions of 108 pre-clinical medical students (69 males, 39 females; mean age 22 years) toward mental illness in Trinidad & Tobago by analysing their responses to a questionnaire based on a case vignette of a young man with a paranoid psychotic illness. 88% felt that medical treatment in hospital was the best means of treating the illness and 86% suggested that discharge should be conditional on regular visits to a doctor. 89% however opposed the patient's marrying into their families and 85% to his teaching their children. This was associated significantly with having a personal relationship with someone having a mental illness (p < 0.03). Surprisingly, 25% believed that mental illness could be caused by supernatural forces, particularly females who were almost twice as likely as males to express this belief.

We present a case of a patient admitted to a psychiatric hospital with psychotic symptoms and cognitive impairment but who was subsequently found to have an anterior interhemispheric falx meningioma. There must be a high index of suspicion for organic brain disease in patients over age 45 years presenting with psychotic symptoms and seizures for the first time.

BACKGROUND: Incidence rates of schizophrenia among UK African-Caribbeans have been reported as high. Various explanations including selective migration and genetic vulnerability have been proposed. METHOD: In one calendar year, all new cases of psychosis presenting to various psychiatric services in two clearly defined geographical catchment areas in Trinidad-one in the rural south and the other an urban area-were studied. Standardised diagnostic instruments were applied and information collected using WHO screening and measurement instruments. RESULTS: A total of 56 cases were collected, giving an incidence rate of 2.2/1000 of broad schizophrenia with a rate of 1.6 for S+ schizophrenia. CONCLUSION: These rates are similar to those from the WHO study in Honolulu and Aarhus, and much lower than the rates for African-Caribbeans in London. The cases were followed up for one year and the poor outcome rate for schizophrenia was 19%. The findings are discussed in a cross-cultural context and suggestions for future research made.

The demographic, ethnic and clinical characteristics of 102 adolescents admitted to the Port-of Spain General Hospital over a 10-month period because of parasuicide were studied. The estimated rate of attempted suicide among adolescents was 94 per 100,000 of the hospital catchment population. Ninety per cent of the sample were females. Fifteen per cent had previously attempted suicide. Twenty-five per cent were clinically depressed, 22% had adjustment reactions, and in 49% no mental illness was detected. In 50% of cases, no further treatment was necessary after the first psychiatric interview. Intra-family conflicts were the most frequent reasons given for the attempted suicides. Girls of East Indian origin attempted suicide more frequently than those of African origin. Adolescents of mixed racial backgrounds attempted suicide less frequently than those of either African or East Indian origins. The findings of the study suggest a need for the adolescent psychiatric services to be upgraded, and for a review of the hospital policy of admitting all parasuicides of whatever degree as this is resulting in unnecessary and costly utilization of hospital beds.

All patients referred for a psychiatric consultation from the adult wards of a General Hospital over a 10-month period were examined. The referral rate was 1.4%. Twice as many female patients were referred as male patients. Parasuicide accounted for 68% of referrals. The most common psychiatric diagnoses were adjustment reaction (41%), depression (23%), alcohol dependence (5%) and schizophrenia (5%). In 30% of referrals, no psychiatric treatment was necessary; 26% were transferred to the psychiatric unit and 17% were discharged to the out-patients' psychiatric clinic. Explanations are offered for the "hidden" psychiatric morbidity in General Hospitals and the high percentage of referrals who did not need psychiatric follow-up. Suggestions are made for a better liaison between physicians and psychiatrists.

The psychiatric inpatients from a defined geographic catchment area of 100,159 were analysed for the year 1986. The inpatient treated prevalence was 5 per 1,000 of the population over 15 years of age. There were 85 long-stay patients and 413 admissions during the year. Thirty-eight per cent of all admissions for 1986 had schizophrenic psychoses, 34% had alcohol and drug disorders, and 15% had affective disorders. Forty-nine per cent of first admissions had alcohol and drug disorders, and 28% had schizophrenic psychoses. Schizophrenic psychosis was the diagnosis in 61% of those patients who had more than 3 previous admissions. Substance abuse, acute schizophrenic psychosis and chronic schizophrenic psychosis accounted for 72% of admissions for 1986. The duration of stay in hospital was longer for female patients than for male patients for each of the main diagnostic categories. The need for epidemiological and hospital utilisation studies to provide essential data for the rational planning of psychiatric services in Trinidad and Tobago is emphasized.

Two hundred and thirty-two psychiatric Outpatients on depot fluphenazine decanoate for more than six months were examined for Tardive Dyskinesia (TD), using the AIMS rating scale, and the prevalence rates of TD at different criteria of severity were assessed. The prevalence rates ranged from 7% for patients with severe TD to 45% for patients with any degree of TD. The sex distribution of patients with TD showed no bias but the female patients were significantly older than the male patients. Increases in prevalence rates of TD were associated with the combination of an anticholinergic anti-Parkinsonian drug with the depot neuroleptic, and with the concomitant use of an oral neuroleptic with the depot preparation. Implications of these findings for the long-term management of schizophrenia are discussed.
