Perceptions about mental illness among pre-clinical medical students in Trinidad and Tobago

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 and Tobago by analysing their responses to a questionnaire based on a case vignette of a young man with a paranoid psychotic illness. 88 percent felt that medical treatment in hospital was the best means of treating the illness and 86 percent suggested that discharge should be conditional on regular visits to a doctor. 89 percent however opposed the patient's marrying into their families and 85 percent to his teaching their children. This was associated significantly with having a personal relationship with someone having a mental illnes (p < 0.03). Surprisingly, 25 percent believed that mental illness could be caused by supernatural forces, particularly females who were almost twice as likely as males to express this belief.(AU)

Psychiatric hospital admission rates in Jamaica, 1971 and 1988

The overall psychiatric hospital admission rates in Jamaica were 136 per 100,000 in 1971 and 69 per 100,000 in 1988. The admission rate for schizophrenia was 69 per 100,000 in 1971 and 35 per 100,000 in 1988. The 49 percent reduction in admission rates over these 17 years is attributed to the introduction of an island-wide community mental health service with psychiatric admission to general parish hospitals in 1972. This admission rate for schizophrenia is five to six times lower than the rate reported for Afro-Caribbeans in the UK by a number of studies, and is more in keeping with the admission rate for schizophrenia reported for the general population in England.

Role of cannabis in psychiatric disturbance

Clinical observation suggests that cannabis is implicated in some types of psychiatric disturbance. A record of admissions to two urban and four rural hospitals in Jamaica is examined along with details of individual cases. One third of male admissions to the psychiatric hospital have used cannabis. Of 74 males admitted to another psychiatric service over a 12-month period, 29 had used cannabis. Ten of these patients were diagnosed as "ganja psychosis" and four others were classified as "marijuana-modified mania." At another psychiatric service, 54 of 223 admissions (24.2 percent) for functional psychosis presented with cannabis usage as a contributory factor. These 54 patients included 14 and seven cases of hypomanic and depressive reactions, respectively. At three other rural general hospitals, psychiatric admissions for psychosis showed 11 of 51, seven of 18, and 39 of 75 patients, respectively, in whom cannabis was considered directly responsible. These findings lend support to the idea of causation of illness or modification of existing illness. The negative findings of controlled studies in the same country are not inconsistent. A suggested classification for adverse reactions to cannabis offerred by one author is recommended, because it is in accord with common local clinical experience.(AU)

Endocrine disease as a cause of mental illness

Two cases of endocrine failure in two sisters were reported. In one, symptoms of acute depression and paranoia followed a severe episode of mumps with complete recovery after thyroid replacement therapy. In the other , symptoms of thyroid and adrenal failure, either primary or due to pituitary failure, were less dramatic but responded to approriate endocrine replacement therapy. The need for adequate facilities for the investigation of endocrine disease in Barbados was stressed, as it was estimated that 0.2 percent of mental or physical disease there is caused by thyroid disorders (AU)
