Canadian training in the clinical neurosciences, neurology and neurosurgery, faces significant challenges. New balances are being set by residents, their associations and the Royal College of Physicians and Surgeons of Canada between clinical service, education and personal time. The nature of hospital-provided medical service has changed significantly over the past decade, impacting importantly on resident training. Finally, future manpower needs are of concern, especially in the field of neurosurgery, where it appears that soon more specialists will be trained than can be absorbed into the Canadian health care system. ⋯ Training in neurology and neurosurgery, as in all medical specialties, has changed significantly in recent years and continues to change. Programs and hospitals need to adapt to these changes in order to ensure the production of fully qualified specialists in neurology and neurosurgery and the provision of optimal care to patients in clinical teaching units.

Review Case Reports
Sarcoidosis presenting as an intramedullary spinal cord lesion.
Sarcoidosis affects the spinal cord in only 0.43% of patients with sarcoidosis. Usually there is systemic involvement prior to the development of cord lesions. We present a case of sarcoid isolated to the intramedullary spinal cord, which was a diagnostic and therapeutic challenge. We review the case and then present a review of the literature with an emphasis on presentation, diagnosis and treatment. ⋯ Fourteen patients have been reported with isolated intramedullary spinal cord sarcoidosis. Current practice supports the role of surgery for biopsy; mainstay of treatment is corticosteroids.

Alteplase for acute ischemic stroke may be the first stroke intervention to have a significant public health impact. In February 1999, this therapy was conditionally licensed in Canada for acute ischemic stroke within three hours of symptom onset. However, considerable controversy exists regarding its safety, its wider applicability outside clinical trials, and its ultimate availability. In this article we review the thrombolytic literature, attempt to answer many of the concerns, provide new guidelines for its use, and cite the need for more information about whom we should and should not be treating with this therapy.

In 1886, Victor Horsley excised an epileptogenic posttraumatic cortical scar in a 23-year-old man under general anaesthesia and discussed his choice of anaesthesia: "I have not employed ether in operations on man, fearing that it would tend to cause cerebral excitement; chloroform, of course, producing on the contrary, well-marked depression." His concerns regarding anaesthesia are reiterated 100 years later as evidenced by the ongoing controversy over the choice of anaesthetic in surgical procedures for epilepsy. The current controversies regarding the necessity for local anaesthesia in temporal lobe epilepsy operations concern the utility of electrocorticography in surgical decision making, its relationship to seizure outcome and the value of intraoperative language mapping in dominant temporal lobe resections. ⋯ Thus, indications which were previously absolute are now perhaps relative. This article reviews the current indications for craniotomy under local anaesthesia in the surgical treatment of temporal lobe epilepsy.
