The goal of successful acoustic tumor surgery is to totally remove the tumor and preserve neurologic function. This paper reviews 132 patients, with particular emphasis on the hospital mortality rate, total removal of the neoplasm, and preservation of facial function and, in 3 instances, hearing.

This paper compares the costs of a categorical clinic model for community hypertension intervention with the costs of two less resource-intensive hypertension programs. Three categories of costs are measured for each program: program costs, patient costs, and time costs. Total costs are expressed in terms of costs per hypertensive patient controlled under each program. When adjusted for differences in hypertension prevalence and screening costs in the three community programs, the cost-effectiveness of the categorical clinic model is questionable. These results suggest that careful analyses of the categorical clinic model in other communities should be conducted before public resources are committed to the establishment of such models on a widespread basis.

The unique medical data resource for the population of Rochester, Minnesota, is centered on the records of the Mayo Clinic and the Olmsted Medical and Surgical Group, which for several decades have provided nearly all medical care in this community. This resource has been utilized in a study of the incidence rates and secular trend in coronary heart disease for the period 1950-1975 among residents of Rochester. A total of 3,080 patients fulfilled the clinical and other criteria for inclusion in this study. The patients, classified by initial manifestation of coronary heart disease, consisted of 1,321 with myocardial infarction, 1,215 with angina pectoris, and 544 with sudden unexpected death. In this paper the background, clinical definitions, and study design are presented.

Beginning in 1974, the Mayo three-community hypertension control program initiated intervention studies in three southeastern Minnesota communities. This paper reports on the blood pressure outcomes 5 years after the inception of graduated programs involving public and professional education, detection, referral, and, in one community, systematic stepped care. Despite differences in local physician-population ratios and organization of medical care, perseverant long-term reductions of blood pressure were noted in all communities. However, the mean diastolic pressures were lower and the number of individuals at goal (diastolic blood pressure 90 mm Hg or less) was higher in the community offering categorical care. These data suggest that while programmatic efforts to control hypertension resulted in favorable blood pressure declines, the outcomes were particularly impressive in the community with a categorical hypertension clinic model offering systematic management of hypertensive patients.
