Job sharing. Part 1.

This article is the first of a three part series discussing the impact of nurses job sharing at University Hospital, London, Ontario. This first article explores the advantages and disadvantages of job sharing for staff nurses and their supervising nurse manager, as discussed in the literature. The results of a survey conducted on a unit with a large number of job sharing positions, concur with literature findings. The second article will present the evaluation of a pilot project in which two nurses job share a first line managerial position in the Operating Room. The third article will relate the effects of job sharing on women's perceived general well being. Job sharing in all areas, is regarded as a positive experience by both nurse and administrators.

[Pacemaker activation by muscular movement].

In recent years impressive progress was achieved in the field of cardiac stimulation. Sometimes atrial systole is not available to increase stroke volume in patients with pacemakers for complete atrioventricular block. We describe a new model of heart pacemaker (Activitrax), which is activated by muscle movement and is responsive to metabolic demands, increasing the pacemaker's firing rate according to exercise. The result which allowed a better quality of life was highly satisfactory.

Lack of type C virus antibodies in systemic lupus erythematosus.

Twelve systemic lupus erythematosus (SLE) and 10 normal sera were similarly reactive in an assay for cytotoxic antibody to type C virus-infected and uninfected cells, but both were less cytotoxic for infected cells. Thus antibodies to type C viruses were not detected in SLE or normal sera, but type C infection may interfere with antibody recognition of other cell membrane antigens.

Diaphragmatic paralysis in motor neurone disease: use of non-invasive investigative and therapeutic techniques.

Two cases of bilateral diaphragmatic weakness are described in which the condition was the presenting feature of motor neurone disease. Inspiratory muscle strength was assessed by a non-invasive technique involving measurements of pressures generated within the mouth. One patient with severe inspiratory muscle weakness is being treated with domiciliary nasal ventilation and has returned to a good-quality life. The other patient with less severe weakness has thus far required no ventilatory support.

[Cryo-treated allo-prosthesis: applications and complications].

From January 1987 to December 1992, fifty two patients aged 1 day to 20 years were implanted cryo-treated homografts into the right-sided position. The patients were diagnosed as having severe Fallot's tetrads, common arterial trunk, transposition of great vessels, vascular bifurcation with pulmonary atresia and isolated pulmonary atresia. The authors implanted 56 homografts, out of them 37 aortic and 19 pulmonary. In the early postoperative period 8 (15.4%) patients died whereas in the late period 1 (1.92%) patient. Out of complications, pseudoaneurysm, calcification with pseudoaneurysm, flap dilatation, and severe prosthesis calcification were found in 1, 1, 1, and 4 patients, respectively. The development of pseudoaneurysms is likely to result from incorrect treatment of donor tissue and to be not so infrequently as previously assumed. To prevent their development is to apply accessory individual sutures to the gaskets in the area of the anterior wall of proximal anastomosis and to use the Gore-Tex material for an external flap.

Acute low back pain findings and management in an academic medical center.

To compare medical records of patients treated for acute low back pain in the departments of Family Medicine, Internal Medicine, Occupational Medicine and Emergency Medicine in an academic medical center to determine if there was variation in patient population, diagnostic and treatment procedures and outcomes. Records were randomly reviewed using a standardized form for patients diagnosed with ICD 9 codes pertaining to back pain. Of the 96 patients with acute back pain seen in outpatient areas, 66 were seen by Family Medicine, 26 by Medical Group Practice (MGP), and four by Occupational Medicine. One hundred seven were seen in the Emergency Department. There was no significant difference in duration or type of pain or the type of findings or treatment. Very few had positive physical findings, (9% outpatient and 10% Emergency Department), but many more, (38% outpatient and 17% ED), had psychosocial findings (smoker, dissatisfaction with work, previous psychiatric history, psychosomatic history, or abnormal social adjustment) documented, Plain films of the lumbrosacral spine done in both practice settings did not change treatment.
