Teleconferencing. Home health administrators and educators enhance graduate education.

In light of the current condition of university budgets, enhancing graduate education can be a challenge for nurse educators. One effective and inexpensive strategy is teleconferencing. This strategy allows graduate students to network with nurse leaders nationwide without the expense of travel. Teleconferencing could also be adapted in other areas to bring service and educational professionals together.

Audit of necropsies in a British district general hospital.

A comprehensive study was made of the value of necropsies carried out over a six month period in Peterborough Health Authority, using a modification of the format proposed by Schned et al in Vermont, United States of America. Cause of death, clinical correlation, clinical factors contributing to death and clinical evaluation of the necropsy were recorded. The principal diseases were cardiac (33%), and neoplastic (29%). The pathologist disagreed with the clinical cause of death in 13% of cases and major unsuspected diagnoses were found in 30%. Seventy nine per cent of necropsies provided additional information, including feedback on clinical investigations. Clinicians' questions were answered fully in 87%. Necropsies were rated as "very valuable" in 44% of cases, "valuable" in 54%, and "of no value" in only 2%. In 14% of cases the clinical consultant stated that the results of the necropsy would affect future clinical practice. These findings underline the essential place of necropsies in both audit and postgraduate education. The format described could conveniently be used by other pathology departments as part of an audit program.

Increased iron absorption in uroporphyrin-treated rats.

Rats were given 59Fe (28 micrograms) together with doses of 0, 2 and 200 micrograms of uroporphyrin III in paired observations. Absorption of 59Fe was determined by comparing whole body counts of the rats 30 min and 7 days after dosing. Prior treatment with 200 micrograms of uroporphyrin twice daily for 3 days was associated with significantly increased 59Fe absorption of 6.2% compared to the absorption of 4.6% without uroporphyrin (control) and 4.6% with a 2-micrograms dose (p less than 0.05).

Congenital tumours of the salivary gland: a case report and review.

A congenital epithelial tumour of the submandibular salivary gland, occurring in a child of 10 months, is described. The lesion appeared benign and consisted of basal type cells, showing ductal and acinar differentiation with myoepithelial cells. The associated fibrous stroma contained blood vessels and small nerve bundles. A few similar lesions have been reported in the past, some of which showed features of malignancy. Although various names have been proposed, we suggest that these lesions represent a single group derived from a primitive cell line and advocate the use of the term sialoblastoma.

Protein gene product (PGP) 9.5 as a reliable marker in primitive neuroectodermal tumours--an immunohistochemical study of 21 childhood cases.

A number of antibodies to neural proteins have been used to demonstrate neuronal differentiation in primitive neuroectodermal tumours. One of them is protein gene product (PGP) 9.5, a neuronal protein isolated from brain, whose function is unknown at present. We have studied differentiation in 21 cases of primitive neuroectodermal tumours of the CNS in children. Immunocytochemical staining was performed for such neuronal markers as: PGP 9.5, neuron specific enolase and synaptophysin, a glycosylated protein associated with synaptic vesicles. Positive staining for PGP 9.5 was present in 16 cases (strong staining in 12), for neuron-specific enolase in 16 cases (strong staining in 10) and for synaptophysin in 10 cases (strong staining in six). Both PGP 9.5 and synaptophysin showed a clear staining pattern with less non-specific background than with neuron-specific enolase. Our findings demonstrate the value of using more than one antibody marker in assessing neuronal differentiation in tumours. The high incidence of positive staining with antibody to PGP 9.5 suggests that this is an essential marker in the panel of antibodies used for the identification of primitive neuroectodermal tumours.

Variant angina pectoris: a clinical and coronary arteriographic spectrum.

The clinical course and coronary arteriographic findings in eight patients with Prinzmetal's variant angina pectoris are reviewed and contrasted to previously reported cases. In six patients with S-T-elevation inferiorly, three had normal coronary arteriograms, one had complete right coronary artery occlusion, one had diffuse triple-vessel disease, and one did not undergo coronary arteriography. In two patients with S-T-elevation anteriorly, severe stenosis of the anterior descending coronary artery was present. Medical treatment in four patients and surgical revascularization of the anterior descending coronary artery in two patients were both accompanied by marked symptomatic improvement. Spontaneous loss of angina occurred in two patients. During 17 months' mean follow-up, seven patients have remained free of angina and one died suddenly. Variant angina pectoris may be accompanied by a variety of coronary arteriographic findings and the prognosis appears more favorable than previously reported.

Nursing research in home health agencies.

It is appropriate and feasible for home care agencies to conduct research. They have a ready population and sample. Many aspects of home care need to be studied to improve the quality of care and the quality of life. The rewards of research can more than justify the burdens. The practical benefits are the strengthening of staff knowledge and expertise through exposure to the process of investigation and to the clinical applications and implications of the findings. The bottom line will be improved patient care.

The ethical dilemmas.

This column has posed the issues and identified resources that home care nurses can use in an attempt to resolve the moral, social, economic, and professional factors that are confronted each day. Ethical dilemmas have been presented. The editor and I invite you to share your success (or lack of it) in resolving the issues you have experienced in caring for your patients. We look forward to hearing from you in an effort to benefit from your experiences.
