[Vasospastic angina pectoris following abortion induced by prostaglandin analogue].

A case of vasospastic angina pectoris with loss of consciousness, bradycardia and seizures induced by medical abortion following administration of mifepristone and gemeprost is reported. The patient had a history of smoking and migraine, and former treatment with ergot alkaloids or serotonin agonists had also resulted in chest pain and lipothymia. The case underlines the importance of obtaining a detailed history of vasospastic disorders in women referred for medical abortion.

Internet course on total quality management.

The Internet provides new opportunities to information-based industries such as universities. If a vast majority of potential customers of our programs have access to the Internet, then it is conceivable that many universities will begin teaching Internet courses and that such courses could, in many cases, replace or at least augment existing face-to-face classroom activities. This paper is an account of one such course at Cleveland State University and the type of policy issues raised by the course at this institution.

Treatment of mandibular angle fractures using one noncompression miniplate.

PURPOSE: This study evaluated the results in patients treated for fractures of the mandibular angle with a single miniplate. PATIENTS AND METHODS: Eighty-one patients with fractures of the mandibular angle were treated by open reduction and internal fixation using one noncompression miniplate with 2.0-mm self-threading screws placed through a transoral incision. No patient was placed into postsurgical maxillomandibular fixation. They were prospectively studied for complications. RESULTS: Thirteen patients with angle fractures (16%) experienced complications requiring secondary surgical intervention. Most of the complications (n = 11), however, were minor and could be treated in the office. Most commonly, intraoral incision and drainage and later removal of the bone plate were required. All patients with minor complications had clinical union. Only two complications required hospitalization for intravenous antibiotics and further surgery. One of these patients had a fibrous union requiring a bone graft. CONCLUSIONS: The use of a single miniplate for fractures of the angle of the mandible is a simple, reliable technique with a relatively small number of major complications.

Rating journals in health care administration. The perceptions of program chairpersons.

The perceived quality of a journal is often a heavily weighted factor in the appraisal of faculty performance. We developed a listing of 53 prominent journals in the field of health care administration and surveyed the chairpersons of the 52 accredited graduate programs in the United States, Canada, and Puerto Rico, asking each to rate the level of achievement of a faculty member who published in each journal. Using the chi-square goodness-of-fit method for a multinomial experiment, we were able to identify six distinct "tiers" of journals and show a relationship between the subject category of a journal and its tier ranking. The implications of the study findings for faculty members are addressed, followed by a discussion of the data limitations and suggestions for future research.

Evaluation of health care service diversification options in health care institutions and programs by portfolio analysis: a marketing approach.

Originally conceived as a technique to assess how well current activities contribute to the attainment of organizational goals, portfolio analysis also can be used as a marketing research tool for considering the relative merits of various diversification options under consideration by institutional decision makers. The authors describe the features of portfolio analysis and its use as a tool in the evaluation of health care diversification options. A case study of a hospital that has employed the method in its corporate planning and marketing efforts illustrates the use of this analysis technique.

Integrating knowledge and behavior: development of a management and career development program for graduate health administration education.

How best to integrate cognitive learning and behavioral skills in health administration education has been a concern of both academics and practitioners for many years. Charged with the education of health care administrators, graduate programs are expected to produce persons who are both knowledgeable about the field in which they plan to be employed and skilled in carrying out the many tasks associated with successful performance in their future roles. This article describes the theoretical basis and design of the management and career development offering (MCDO) of Widener University's Graduate Program in Health and Medical Services Administration, the key objectives of which are to integrate cognitive learning with practical experience and to provide a mechanism for the development of needed professional skills in a low-risk academic atmosphere. It was clear that these objectives could not be achieved entirely within a traditional academic curriculum, nor were they always appropriately treated there. However, the complexity of the health care field, the growing demands placed on administrators, and conflicts arising within and between roles increase the necessity to integrate these theoretical and behavioral skills.

Strategic marketing applications of conjoint analysis: an HMO perspective.

The purpose of this article is to demonstrate how data from a conjoint analysis study can be used to help determine the most appropriate marketing mix for an operational HMO which is entering a new market--the geriatric population. Included are two features which are absent in previous articles on health care applications of conjoint analysis: external validation of results, and a demonstration of how conjoint analysis can be used to simulate market responses to changes in the provider's marketing mix.

Measuring consumer preferences for ambulatory medical care arrangements.

This paper describes how conjoint analysis can be applied to health care marketing. Data from a sample of 73 university students were used to estimate part-worth values for different levels of attributes of ambulatory care arrangements. A high degree of comparative validity was found.

Beyond expectancy theory: an integrative motivational model from health care.

Expectancy theory has been criticized for its omission of normative, habitual, and other motivational elements. This paper describes the sources and features of an integrative motivational model from the field of preventive health care that combines expectancy/valence factors with habitual, normative, and conative motivational elements. The model is viewed as having implications for work motivation as well.

Psychosocial determinants of breast self-examination.

To explore the psychosocial determinants of breast self-examination (BSE) among women, we studied a stratified random sample of 264 women students, faculty, and staff in a university community. The dependent variable of the study was self-reported frequency of BSE, and predictors included measures of general health predispositions, variables of the Health Belief Model, the impact of a woman's social network, a set of secondary non-health-related barriers and benefits, and the woman's evaluation of her personal health care system. Analysis of the data showed strong relationships between most of the predictor variables and BSE. Regression analysis showed that variables measuring a woman's recent experience in the health care system were stronger predictors of BSE practice than intrapersonal "health belief" variables. However, the independent variables included in the regression accounted for almost 35 percent of the total variance in BSE practice.
