- OBJECTIVE: To assess the agreement between the Sunnybrook facial nerve grading system and the House-Brackmann and Yanagihara systems. STUDY DESIGN: Prospective clinical facial nerve grading. SETTING: Tertiary referral center. PATIENTS: One-hundred assessments, 94 in patients with Bell's palsy and 6 with herpes zoster. INTERVENTION: Diagnostic. MAIN OUTCOME MEASURES: Evaluation according to the weighted regional Sunnybrook system, the gross House-Brackmann system, and the unweighted regional Yanagihara system. Weighted kappa statistics was used to measure agreement between the grading systems. RESULTS: The average weighted kappa value between the Sunny-brook, House-Brackmann, and Yanagihara grading systems was 0.65; kappa values increased temporally (but not statistically significantly) up to day 180. The highest agreement value, 0.72, was found between the Sunnybrook and Yanagihara grading systems. The weighted kappa value between the Sunnybrook and House-Brackmann systems was 0.59. In Sunnybrook gradings less than 63, there was an overlap between House-Brackmann scores of III to VI. Reliable conversion tables between the gross House-Brackmann system and the regional Sunnybrook and Yanagihara systems could not be established. CONCLUSION: The Sunnybrook system scores at the same agreement level as the House-Brackmann and Yanagihara grading systems. There is an evaluative difference between the weighted regional Sunnybrook and the gross House-Brackmann systems. Substantial agreement was found between the regional Sunnybrook and Yanagihara scales. Sunnybrook grading is easy and quick. By adding objective measurements and additional secondary defects, the Sunnybrook system can be an alternative to the other predominating grading systems.

- To study the electroneurographic facial muscle pattern in Bell's palsy over time, electroneurographic recordings in the frontalis, orbicularis oculi, nasalis, and mentalis muscle regions were performed early (mean, day 11) and 1 and 3 months after the onset of the condition in 30 consecutive patients. The correlation between facial muscle electroneurographic recordings over time was also calculated. An additional aim was to assess whether further prognostic information could be obtained by electroneurographic recordings in more than one facial region. The recovery pattern was similar in all 4 facial regions. Initially, the correlation between the facial recordings was weak (r = 0.20-0.27), but it was improved at follow-up examinations (r = 0.33-0.65). Favorable outcome in 23 of 24 patients (96%) could have been predicted by the initial nasalis and/or mentalis recordings. The gap between patients with favorable outcome and patients with unfavorable outcome increased when the average electroneurography values were calculated from 1, 2, and 4 muscle recordings (4%, 8%, and 15%, respectively). Our results indicate that in Bell's palsy, electroneurographic examination of more than one facial muscle region may add prognostic information and that the degree of degeneration is initially different in the nerve branches.

- Objective - To find evidence of the effectiveness of physicians working in primary care. Design - Systematic literature search in the Medline and Cochrane databases. Material - Out of 7223 titles found in the search, 45 studies, comparing, from different aspects, primary care with specialist care, were extracted. Main outcome measures - Health indicators, health care costs, quality of health care. Results - Primary care contributed to improved public health, as expressed through different health parameters, and a lower utilisation of medical care leading to lower costs. Physicians working in primary care, in comparison with other specialists, took care of many diseases without loss of quality and often at lower cost. The organisation of primary care was important in respect of reimbursement by capita tion, more group practices, higher personal continuity, and having generalists as primary care physicians. Conclusions - To compare the effectiveness of primary care and specialist care is a complex task and there are limitations in all studies. However, we have found evidence that increased accessibility to physicians working in primary care contributes to better health and lower total costs in the health care system. It is also clear that studies with evaluation of how to most effectively organise primary care are far too few. There is an extensive need for future research in this area, a suitable task for collaborative research between the Nordic countries.

- Subarachnoid hemorrhage (SAH) is not an unusual disease in an elderly population. The clinical outcome has improved over time. It has been suggested that elderly SAH patients would benefit from endovascular aneurysm treatment. The aim of this study was to evaluate technical results and clinical outcome in a series of elderly SAH-patients treated with endovascular coil embolization. Sixty-two patients (> or = 65 years) presenting with aneurysmal SAH underwent early endovascular coil embolization at Uppsala University Hospital between September 1996 and December 2000. In all 62 cases included in the study, endovascular coil embolization was considered the first line of treatment. Admission variables, specific information on technical success, degree of occlusion and procedural complications, and outcome figures were recorded. Clinical grade on admission was Hunt and Hess (H&H) I-II in 39%, H&H III in 27% and H&H IV-V in 34% of the patients. The proportion of posterior circulation aneurysms was 24%. Coil embolization was successfully completed in 94%. The degree of occlusion of the treated aneurysm was complete occlusion in 56%, neck remnant in 21%, residual filling in 11%, other remnant in 5% and not treated in 6%. The rate of procedural complications was 11%. Outcome after 6 months was favorable in 41%, severe disability in 36% and poor in 22%. Favorable outcome was achieved in 57% of the H&H I-II patients, 47% of the H&H III patients and 17% of the H&H IV-V patients. Endovascular aneurysm treatment can be performed in elderly patients with SAH with a high level of technical success, acceptable aneurysm occlusion results, an acceptable rate of procedural complications and fair outcome results.
