Voices from different places: but why a medical school faculty?

Interdisciplinary collaboration between nursing and medicine is a valued goal, but one which is difficult to achieve. Two nurses who are faculty members in medical schools reflect on their unique roles and how these encompass interdisciplinary research, teaching, and practice.     

Patient-centred evaluation and rehabilitative care

The evaluation of health care outcomes is becoming increasingly important in today's health service The wide range of measures used to evaluate these outcomes often makes clinical audit difficult and the comparison of research papers almost impossible In this paper we will discuss some of the issues surrounding outcome measurement in rehabilitative care, examine one of the most commonly used outcome measures from this area (the Barthel Index) and consider Goal Attainment Scaling, a technique which offers both clinicians and researchers the opportunity to evaluate health care outcomes on the basis of patient-centred practice We have identified certain methodological problems that need to be addressed if Goal Attainment Scaling is to become an acceptable measure in the area of physical rehabilitative care     

A preliminary study into the dental health status of multiple sclerosis patients

Multiple sclerosis (MS) is an inflammatory disease of unknown etiology involving the central nervous system. Since MS affects the whole body, orofacial aspects of the disease must be expected, particularly since loss of muscular coordination may result in a diminished ability to maintain oral hygiene. This preliminary study examined the dental health status of 22 volunteer MS patients. A questionnaire collected data regarding medical and dental histories and socieo-demographic information. Extra- and intra-oral examinations were carried out on all subjects to determine the particular dental treatment needs of this special group. The DMFT and CPITN scores for this group did not indicate that MS patients were more susceptible to dental caries or periodontal disease. However, the prevalence of trigeminal neuralgia and symptoms of TMJ dysfunction in the group studied indicated that these conditions may be manifest in MS patients and warrant further investigations.     

Dexmedetomidine Produces Similar Alterations in the Determinants of Left Ventricular Afterload in Conscious Dogs before and after the Development of Pacing-induced Cardiomyopathy

Background: The authors tested the hypothesis that intravenous dexmedetomidine produces alterations in left ventricular (LV) afterload that are deleterious to cardiac performance in conscious dogs with pacing-induced cardiomyopathy.

Methods: Dogs (n = 8) were fitted with instruments for long-term measurement of LV and aortic blood pressure, aortic blood flow, and subendocardial segment length and received dexmedetomidine (1.25, 2.5, and 5 [micro sign]g/kg) in a cumulative manner before and after 19 +/- 3 (mean +/- SEM) days of rapid LV pacing. LV afterload was measured with aortic input impedance [Zin ([Greek small letter omega]) and quantified with a three-element Windkessel model. Hemodynamics and Zin ([Greek small letter omega]) were assessed under control conditions and 5 and 60 min after administration of each dose.

Results: Dexmedetomidine caused early and late decreases in heart rate, the maximum rate of increase of LV pressure, mean aortic blood flow, and stroke volume in dogs before and after pacing. Dexmedetomidine caused similar early increases in total arterial resistance and decreases in total arterial compliance in dogs before and after pacing. Early dexmedetomidine-induced increases in resistance and decreases in compliance caused similar reductions in mean aortic blood flow in cardiomyopathic compared with healthy dogs. Resistance and compliance returned to control values, and characteristic aortic impedance decreased late after dexmedetomidine in healthy dogs. In contrast, resistance remained elevated late after dexmedetomidine in dogs with dilated cardiomyopathy.     

Transposition of the great arteries and isolated origin of the sinus node artery

We report the cases of 2 newborns who underwent at 7 days of age an arterial switch operation for transposition of the great arteries with a rare coronary anomaly: the left and right coronary arteries originated with a single ostium from sinus 1 and the sinus node artery had an isolated origin from sinus 2. The sinus node artery was reimplanted into the new aorta in both patients. Both babies were discharged in sinus rhythm. Preserving the vascularization of the sinus node may avoid the occurrence of postoperative atrial rhythm disturbances.     

Advancing Nursing Practice with a Unit-based Clinical Expert

Objective: To explore patterns in the practice of nursing and patient outcomes.
Design: Qualitative field research.
Population, Sample, Setting: Populations were critical care nurses and critically ill adult patients in the 10-bed medical critical care unit of a 900-bed teaching hospital. A convenience-purposive sample of 27 nurses and 31 patients was studied in 1985.
Methods: Six months of participant observation, unstructured interviews, and the constant comparison method of grounded theory.
Findings: Markedly different patterns were found in expert and nonexpert practice. The substantive theory of conversion helped explain how the majority of nonexpert nurses advanced their practice. The metaphor of catalyzed conversion captures how a unit-based expert nurse serves as a catalyst to advance the practice of nonexperts. Presence, defined as the way of being within a given clinical context, differentiated nurses.
Conclusions: (a) Expert and nonexpert practices are substantively different, (b) Expert and nonexpert practice results in different patient outcomes, (c) Conversion helps explain changes in nonexpert practice.
Clinical Implications: A unit-based expert nurse can increase patient-focused care.     

Speech-language pathology and dysphagia: A brief historical perspective

In the past decade, speech-language pathologists have taken a leading role in the management of services for patients with oropharyngeal dysphagia. This article presents the historical perspective of this role, the rationale for assuming the responsibility, and suggests directions for continued involvement.     

A Psychosociocultural Perspective, Part 2

Building on the foundation of understanding and comprehensive assessment of battered women, this article addresses service planning and intervention. Strategies are approached within the framework of a Crisis Paradigm developed from field research with battered women and their families. They include mechanisms such as support groups which link crisis service to the long-term needs of battered women, and systematic approaches to removing the obstacles which keep women victimized. An Assessment and Service Planning Guide (ASPG) is proposed for inclusion in routine health care of abused women. The article concludes with strategies for preventing violence at interpersonal and societal levels.
