Comparative StudyPreoperative treatment of ruptured intracranial aneurysms with tranexamic acid and monitoring of fibrinolytic activity.
The fibrinolytic activity in cerebrospinal fluid has been monitored by determination of levels of fibrin split products (FSP) in 23 patients with ruptured intracranial aneurysms. In 20 of these 23, FSP was found in the cerebrospinal fluid (CSF), with levels ranging from 10 to 80 micrograms/ml. ⋯ These results suggest that there exists a localized fibrinolytic activity, and monitoring the FSP levels in the CSF may be a simple and accurate method for controlling the efficiency of antifibrinolytic therapy. Thus, treatment could be begun with a lower dose, which could be increased later as deemed necessary from the results of careful monitoring.

Retrospective analysis of 22 patients with chronic pain treated by peripheral nerve stimulation.
Twenty-two patients with chronic pain, chiefly from posttraumatic neuropathy, were treated by implanted peripheral nerve stimulators located proximal to the pain. Thirteen of these (62%) have experienced pain control for an average of 25 months. ⋯ There are theoretical and practical advantages to electrical stimulation and proximal portions of the peripheral nervous system. The surgical technique for implantation is described and the necessity for reoperation in some patients is explained.

Pain reduction in amputees by long-term spinal cord stimulation. Long-term follow-up study over 5 years.
This follow-up study analyzes the results of dorsal column stimulation instituted between 1972 and 1974 for the relief of pain in 84 patients, including 64 amputees. Good results decreased from 52.4% after 2 years of stimulation to 39% after 5 years. Special therapeutic problems in amputees are discussed.
