Heart-brain interactions in cerebral ischaemia: a non-invasive cardiologic study protocol.

The cardiologic evaluation of patients with cerebral ischaemia should be aimed at: (1) identifying potential cardiac sources for cerebral emboli, (2) detecting a coexisting ischaemic heart disease, even asymptomatic. The present data concerns a ten-year experience of a systematic cardiologic evaluation of patients admitted to the 1st Division of Neurosurgery, Bellaria Hospital, Bologna, Italy, for cerebral ischaemia. A two-dimensional echocardiography was carried out in 344 consecutive patients (mean age 53 years), cardiac abnormalities were observed in 92 (28%) out of the 328 cases with technically adequate examination, embologenic lesions in 57 (17%). In 18 cases the cardiac lesion was unknown before the cerebral event. An exercise ECG testing was carried out in 322 patients (mean age 56 years), resulting in abnormal in 69 out of the 258 with adequate examination (17%). A subsequent exercise 201Tl myocardial scintigraphy confirmed the presence of ischaemic heart disease in 58 cases. Among patients unable to perform an adequate exercise, a dipyridamole 201Tl myocardial scintigraphy was performed in 38 cases showing perfusional defects in 23 (60%), while a dipyridamole echocardiography was performed in 25 cases showing wall motion abnormalities in 9 (36%). A 24-h Holter monitoring was performed in 65 cases: arrhythmias were detected in 27 patients (41%), but a correlation with the cerebral event was suggested only in 3 cases with atrial fibrillation. According to our experience patients with recent ischaemia should be submitted to the following non-invasive cardiologic screening: (1) exercise ECG testing followed, if abnormal or indeterminant, by 201Tl myocardial scintigraphy in all patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Intramedullary spinal cord ependymomas--a study of 45 cases with long-term follow-up.

Of the 62 patients with intramedullary spinal cord ependymoma treated surgically at our Neurosurgery Division between January 1951 and December 1990 45 had a follow-up of at least 3 years and the longest 30 years. The 28 conus-cauda equina-filum ependymomas operated during the same period are not considered in this study. An analysis of our cases and of the larger published series shows that favourable prognostic factors, apart of course from total tumour removal, which is now usually possible, are a site below the high cervical segments and a mild pre-operative symptom pattern. Patient age at diagnosis, tumour size and "low dose" (< 40 Gy) radiotherapy seem to have no influence on the prognosis. Aggressive surgical removal is the treatment of choice and also for long-term recurrence.
