The unusual osteochondroma: A case of snapping scapula syndrome and review of the literature.

Snapping scapula syndrome is a rare condition characterized by crepitus of the scapula on motion of the ipsilateral upper extremity. It may be quite painful and disabling. The majority of cases are due to bursal and muscular disorders. Snapping scapula syndrome secondary to an underlying osteochondroma is an even more infrequent phenomenon. The case presented highlights the unusual post pubertal growth of an osteochondroma of the scapula that progressed to develop a snapping scapular syndrome. Review of the literature revealed less than fifty reported cases of this phenomenon secondary to an underlying osteochondroma.

A nursing association's leadership in primary health care: policy, projects, and partnerships in the 1990s.

This paper documents the work of one provincial nursing association, the Registered Nurses Association of British Columbia (RNABC), to promote primary health care (PHC) as the foundation of the health-care system. In 1990 the RNABC embarked on a comprehensive policy program to influence change from a nursing perspective. A wide array of strategies was used over a 10-year period to help make PHC a reality in British Columbia's health-care system. Successful strategies used during this period included: writing and distributing policy papers, conducting and evaluating demonstration projects, and developing partnerships with other groups. Some of the projects and their outcomes are highlighted, followed by a critical reflection on lessons learned through the various initiatives. Although remarkable achievements were made from the RNABC's policy work during the 1990s, the advancement of PHC requires further collaborative efforts using multiple strategies.

Effects of angiotensin II on remodelling of the airway and the vasculature in the rat.

Airway remodelling occurs in chronic asthma. Angiotensin II promotes growth in cardiovascular remodelling. Since the renin-angiotensin system is activated in acute severe asthma, we hypothesized that angiotensin II has a role in airway remodelling. A total of 14 young male Wistar rats were randomly divided into two groups. All received 2-week infusions of bromodeoxyuridine, and the experimental group also received angiotensin II. Blood pressure rose in the angiotensin II-infused group [mean levels: pre-infusion, 134.9 (S.D. 14.7) mmHg; post-infusion, 197.1 (22.5) mmHg], and expression of renin mRNA in the renal juxtaglomerular cells was suppressed in these animals. The proportion of bromodeoxyuridine-positive cell nuclei was no different in the airways of control and angiotensin II-infused animals for smooth muscle [mean bromodeoxyuridine index: control, 8. 6% (S.E.M. 1.1%); angiotensin II, 9.3% (1.1%)], epithelium [control, 16.7% (2.3%); angiotensin II, 16.0% (2.2%)] and adventitia [control, 26.4% (2.2%); angiotensin II, 26.6% (2.4%)]. In the arteries, bromodeoxyuridine indices were higher in the angiotensin II-infused rats [18.4% (2.3%)] than in the control animals [9.4% (2.8%)], but no difference was found in the veins [12% (2.9%) and 11.4% (2.6%) respectively]. Morphometry of the airway wall and mesenteric vasculature was no different in the two groups. Therefore a 2-week infusion of angiotensin II increases blood pressure and DNA synthesis in the mesenteric arteries, but does not cause airway remodelling, in the rat.

Public health nursing in Japan: new opportunities for health promotion.

Major changes are taking place in public health nursing in Japan. These include significant developments in employment, education, and roles of public health nurses (PHNs). Demographic and economic factors have prompted the Japanese government to focus health service delivery on community-based care, particularly for the growing elderly population. Public health nurses are redefining their roles and are assuming important functions in planning, implementing, and evaluating community health programs for the elderly. Japanese PHNs are using a variety of health promotion strategies to initiate change at the local level. This article presents two case studies to highlight the leadership role of PHNs in creating new services that foster healthy communities.

Primary health care in action.

In a 40-page report on the Comox Valley Nursing Centre Demonstration Project RNABC says the project showed what nurses can do when they are allowed to practice the full scope of their profession. Overall, the project was a success in making a contribution to understanding the principles of primary health care and community-based nursing practice.

Hospital nurses and health promotion.

This study examined the role of acute-care nurses in health promotion (HP), using a survey designed to measure the knowledge, attitudes, and practices of nurses in relation to HP. Staff nurses in eight British Columbia hospitals surveyed in 1992 responded that HP is an integral part of nursing care, yet several barriers in the hospital environment inhibit their efforts in this domain. The perceived barriers are lack of time, insufficient resources for patient teaching, and lack of continuity of care. Respondents identified positive features as the attitudes of patients and families, supportive colleagues, and hospital support for HP activities. The study concludes that acute-care nurses are an underutilized resource for HP. The challenge is to make more effective use of nurses' knowledge, attitudes, and skills in promoting health in the hospital setting.

Vision for the future of public health nursing: a case for primary health care.

Canada has embraced the goal of the World Health Organization to achieve health for all. This has created a paradigm shift from a focus on direct care to include health promotion and community development, consistent with a primary health care approach. Nevertheless, a clearly articulated vision for the role of public health nurses (PHNs) is lacking. Despite the fact that PHNs make up the largest group of health care workers in the community, their collective opinions and ideas regarding their own practice are seldom sought in a systematic manner. We conducted a survey of public health nurses in British Columbia. Using a two-wave Delphi approach, PHNs were asked to define issues for the future of public health nursing, and to state publicly their preferences for change and transformation. The responses were rank ordered, analyzed, and compared with recent nursing and health care literature to interpret their content. The PHNs' visions for tomorrow agree with concepts of primary health care and community development, and have implications for community health nursing's practice and education.

Public health nurses' vision of their future reflects changing paradigms.

Health care over the past decade has undergone important changes that have implications for public health nursing. The focus of public health has expanded, as a result of the World Health Organization establishing the goal of "Health for All by the Year 2000," with its strategy of primary health care. To be active participants in this expansion, public health nurses must be more explicit about their current contributions to health care systems; develop nursing frameworks consistent with the systems' changing goals; and articulate their visions of the future. It is clear that the medical paradigm of health care services needs to change to one of primary health care. Based on results of a recent public health nursing research study, a conceptual framework for the future practice of public health nursing was developed.

The quality of diabetic care in a London health district.

In order to assess the quality of care in a community-wide sample of diabetic patients, a study was performed on 217 such patients identified in three group practices in an east London health district. Only 46% of the patients were currently attending a hospital. In the two years before review, 64% of patients had had their blood pressure recorded and 59% had had retinal examinations. Levels of glycosylated haemoglobin were significantly higher in patients on insulin than in those on oral regimes (P = 0.0004). The mean level of glycosylated haemoglobin was higher in patients from Social Classes III, IV, and V than in patients from Social Classes I and II (P = 0.005), but there was no difference in level between those patients attending hospital and those attending their general practitioners after accounting for differences in these two populations (P = 0.19). Over 50% of all diabetic patients in this study had levels of glycosylated haemoglobin which may indicate vulnerability to microvascular disease.
