Two hundred and thirty-five patients suffering from newly diagnosed epilepsy were randomly allocated to treatment with either oxcarbazepine or carbamazepine in a double-blind multi-centre study. After a titration phase (between 4 and 8 weeks), the optimal individual dose of trial medication was determined and treatment with that dose was continued for another 48 weeks. The criteria for assessment were: efficacy--seizure frequency, EEG tracings, global evaluation; tolerability--side effects observed by the patient or the investigator, laboratory tests; other assessments--blood pressure and heart rate, carbamazepine and 10,11-dihydro-10-hydroxycarbamazepine trough serum levels. The results of the study showed the following: no significant difference in seizure frequency between oxcarbazepine and carbamazepine; no correlation between the therapeutic effect and the EEG findings in either treatment group; oxcarbazepine caused significantly fewer (P = 0.04) 'severe' side effects than carbamazepine; global evaluation of tolerability demonstrated a trend towards the better tolerability of oxcarbazepine; no correlation was observed between either efficacy or tolerability and the actual serum trough levels of antiepileptic drugs; clinically relevant abnormal laboratory test findings were observed in 2 patients, both on carbamazepine. The authors consider oxcarbazepine to be a valuable alternative to carbamazepine, particularly in patients who develop side effects which prevent optimal seizure control.

Epilepsy after stroke.

A retrospective follow-up of 200 consecutive stroke patients [ischemic brain infarction (IBI) 157, intracerebral hemorrhage (ICH) 20, subarachnoid hemorrhage (SAH) 23] who were in need of ambulatory rehabilitation was conducted for a mean period of 40 months after stroke. Epilepsy developed in 33 (17%) patients. The occurrence of epilepsy was 14% in IBI, 15% in ICH, and 35% in SAH. Significantly more patients developed epilepsy in the SAH group than in the IBI group (8 of 23 vs. 22 of 157, p less than 0.05). Of the 33 patients, 15% had their first seizures within the first 2 weeks after stroke, and 55% developed epilepsy in 6 months. Forty-eight percent of the patients had generalized seizures. Antiepileptic drug (AED) treatment was started in 28 of 33 patients, of whom 17 still had seizures during follow-up. Epilepsy was an important consequence of stroke among patients who needed rehabilitation, especially in SAH patients. In most, this was due to arterial spasm leading to IBI.

Seizures associated with propofol anesthesia.

Propofol is a new, fast-acting intravenous (i.v.) anesthetic. Involuntary movements or epileptic seizures have occurred during or after propofol-induced anesthesia in approximately 50 reported cases; a third of the patients have had epilepsy. We report 5 patients with seizures in association with propofol anesthesia. A female epileptic patient developed severe status epilepticus; the other patients with short-lasting seizures had no previous epilepsy. Although propofol has been used in treatment of patients of status epilepticus, the risk of precipitation of epileptic seizures warrants consideration especially when planning anesthesia for epileptic patients.

The profile of recovery from stroke and factors influencing outcome.

The recovery from stroke of 154 survivors out of 255 stroke patients was analyzed. The outcomes documented were: discharge from hospital, activities of daily living (ADL) and return to work. A clear improvement in neurological and neuropsychological deficits was seen from the acute stage to three months, and this continued to twelve months, but to a lesser degree. 69% and 78% respectively, of the patients were at home three and twelve months after stroke. Independence in ADL increased from 32% acutely to 62% and 68% by three and twelve months, respectively. Of those gainfully employed prior to stroke, 55% had returned to work after twelve months. As a group, SAH patients seemed to recover better, but, for those that could be age-matched with infarction patients, there was no difference in outcome. Old age, acute stage hemiparesis, impairment of intelligence and memory, visuoperceptual deficits, nonadequate emotional reactions, and living alone all had a major negative influence on outcome. This study suggests that neurological and neuropsychological deficits, as well as emotional reactions, influence the outcomes after stroke, and all should be taken into consideration in prognosis.

Prognosis of patients with unilateral extracranial occlusion of the internal carotid artery.

One hundred fifty-five patients (121 men and 34 women) had an angiographically verified unilateral internal carotid artery (ICA) occlusion immediately after carotid bifurcation. The median follow-up period was 53 months. Forty-five percent of the patients were fully independent in the activities of daily living (ADL), 22% required assistance in ADL, 11% were disabled, and 22% died within the follow-up period. The mortality rate was exceptionally low compared with previous series. A life-table analysis of the material gave a 94% probability of surviving the first year, 84% the third year, and 78% the fifth year. Young age was favorable in regard to functional recovery, but it had no influence on mortality. The condition at the acute stage was the most important clinical sign in predicting the prognosis. The prognosis of mortality and functional recovery was poorer for smokers than for nonsmokers, and hypertension had no effect on prognosis. Cerebrovascular disease and coronary heart disease were found to be the cause of death with equal frequency in this study.

Prognosis of patients with middle cerebral artery occlusion.

The long-term prognosis of 78 stroke patients with occlusion of the middle cerebral artery (MCA) or its branches is described. The mean age of the patients was 44 years. The mortality rate in the acute phase was 5%. The acute and total mortality rates of men were higher than those of women (p less than 0.05). Life-table analysis gave 94% probability for one year's survival, 84% for three years' survival, and 78% for five years' survival. Subsequent strokes were twice as common as cardiovascular events as the cause of death. Seventy-two percent of the survivors became fully independent in activities of daily living (ADL) , 27% required assistance, 1% was totally disabled, and 43% returned to work. Left-sided occlusion was overrepresented in those who died (p less than 0.00(1) and those who returned to work (p less than 0.05), and right-sided occlusion was overrepresented in those who required assistance in ADL (p less than 0.05).
