RESUMO
Advanced technology has enhanced our ability to diagnose and treat critically ill patients thereby assisting in prolonging life for many. However, its high cost has been prohibitive, and it may impose more burdens than benefits on some patients. Although technological advances has accelerated social change, many have also fuelled legal and ethical concerns. Consequently, the rationale for the use of advanced technology in the care of criticaly ill patients should be clear and ethically justified.(AU)

A case of a 36-year-old woman with a past history of uterine leiomyosarcoma and an an intracerebral metastasis is reported. The patient presented with a 24-hour history of severe headache with coma, and the CT findings were consistent with a metastatic lesion. Pathological examination of the operative specimen showed features of a leiomyosarcoma. Uterine leiomyosarcoma is an uncommon tumor and metastasis to the brain is rare (AU)

A statistical survey of the incidence, age and sex distribution, and preferential sites of occurrence of tumours of the central nervous system observed at the University Hospital of the West Indies during a 15-year period is presented. Four hundred and seventy-six histologically confirmed neoplasms were recorded. Intracranial tumours were 7 times as common as those of the spinal cord. Of 416 intracranial neoplasms, there were 40 percent neuropithelial tumours, 21 percent meningiomas, 15 percent pituitary adenomas, 9 percent metastatic lesions, 6 percent congenital tumours, 5 percent vasoformative tumours, 3 percent nerve sheath tumours and 1 percent unclassified neoplasms. Men and women were equally affected. Meningiomas and pituitary adenomas were more frequent than in other reported series. Metastases were relatively more frequent in the spinal than in the intracranial group. Of the primary spinal tumours, those of nerve sheath origin were nearly three times as common as the meningiomas (AU)

A large intracranial teratoma which replaced the entire brain is described in an hydrocephalic foetus which was aborted at the 25th week of gestation. This very rare condition is reported for the first time in the Caribbean literature (AU)

The incidence of primary neoplasms of the central nervous system in Trinidad is less than 1 case per 100,000 population per year. There is no significant difference in the sex and age distribution of the cases, but a definite racial difference is seen in the frequency of different CNS neoplasms (AU)

A case is reported of a 21 year old man with polycythaemia and a vascular frontal lobe tumour that was histologically compatible with the diagnosis of haemangioblastoma. On review of the English literature no case could be found of polycythaemia associated with supratentorial haemangioblastoma (AU)
