In 1996 and 1997, 52 patients were admitted to the Princess Margaret Hospital, Nassau, Bahamas, with a confirmed diagnosis of acute myocardial infarction (AMI). The average time to presentation after the onset of symptoms was 18 hours, with 56% of patients presenting within 12 hours. Risk factors identified for ischaemic heart disease were hypertension (77%), obesity (62%), diabetes mellitus (35%), tobacco smoking (25%), a family history of coronary artery disease (17%) and hypercholesterolaemia (8%). ⋯ In hospital post myocardial infarction complications were angina (23%), arrhythmias (12%) and cardiac failure (10%). The average hospital stay was eight days, with a mortality rate of 19%. These results show that there is considerable room for improvement, particularly in the use of thrombolytic therapy, to ensure that all patients receive optimal acute and post myocardial infarction care.

One per cent of all brain tumours and twenty per cent of meningiomas eventually develop an extracranial extension. The least common site is the neck. We report a case of malignant meningioma with extension into the neck of a 39-year-old male.

Case Reports
The prophylaxis of acute rheumatic fever in a pair of monozygotic twins. The public health implications.
Recurrent acute rheumatic fever and rheumatic heart disease can be prevented by antibiotic intervention. We report the case of genetically identical twins, one of whom had overt rheumatic fever, received penicillin prophylaxis and did not have rheumatic heart disease. The other must have had inapparent rheumatic fever, received no chemotherapy prophylaxis and proceeded to develop rheumatic heart disease. ⋯ This case provides further evidence of a genetic predisposition to rheumatic fever and demonstrates the continued value of penicillin in the prophylaxis of acute rheumatic fever. It emphasises the need to maintain the integrity of preventive programmes against rheumatic fever worldwide. Studies which explore the HLA and other genetic linkages with rheumatic fever should be encouraged.

Sera from 111 patients with trauma injuries, who presented to the Accident and Emergency Unit (A&E), University Hospital of the West Indies, during a 3-month period, were screened for blood alcohol. Urine specimens were analysed for metabolites of cannabis and cocaine. Sixty-two per cent (62%) of patients were positive for at least one substance and 20% for two or more. ⋯ Cannabis was the most prevalent substance in all groups. Fifty per cent (50%) and fifty-five per cent (55%) of victims of road accidents and interpersonal violence, respectively, were positive for cannabis compared with 43% and 27% for alcohol, respectively. There was no significant difference in Hospital Stay or Injury Severity Score between substance users and non-users.
