Randomized Controlled Trial Clinical TrialFibrinolytic activity after subarachnoid haemorrhage and the effect of tranexamic acid.
Seventy-four patients with recent subarachnoid haemorrhage were randomly allocated to placebo or tranexamic acid treatment. Fibrinolytic activity in the blood and cerebrospinal fluid was assessed before treatment, one week later and two weeks later. The natural history of fibrinolysis following subarachnoid haemorrhage was obtained from analysis of the placebo group. ⋯ Complications such as rebleeding, hydrocephalus or cerebral thrombosis could not be predicted from analysis of fibrinolytic activity. Tranexamic acid treatment resulted in a reduction in cerebrospinal fluid and blood plasminogen activity. The relevance of fibrinolysis in cerebrospinal fluid and blood to the management of subarachnoid haemorrhage is discussed.

Spinal cord stimulation in 112 patients with epi-/intradural fibrosis following operation for lumbar disc herniation.
A total of 112 patients with epi-/intradural fibrosis following operation for lumbar disc herniation were treated by spinal cord stimulation. Lumbosacral spinal fibrosis is seen particularly often after extensive and repeated operations. Radicular pain responds better to stimulation than back pain. ⋯ Among about 5,000 patients who underwent surgical treatment for lumbar disc herniation, an indication for spinal cord stimulation was found in 1.5%. By comparison, the frequency of the "last resort" procedure of microsurgical cordotomy was 0.3%. We no longer use other ablative methods like extirpation of spinal ganglia.

We present a programme of Neurosurgery concerning pre- and post-graduate education. Objectives are divided into general objectives, intermediate and specific. We suggest also a syllabus for students and another for residents, containing a list of theoretical lectures, seminars and guidelines for practical tuition. ⋯ S. We emphasize the need for personal teaching as the only element of general guidance for the programme. We also emphasize the necessity of criticism, change and evolution, in order to perfect the programme we are offering.
