Prevalence of autoimmune diseases in islet transplant candidates with severe hypoglycaemia and glycaemic lability: previously undiagnosed coeliac and autoimmune thyroid disease is identified by screening.

AIMS: Autoimmune diseases such as Addison's or coeliac disease can contribute to hypoglycaemia or malabsorption and are more common in Type 1 diabetes (T1DM). This brief report describes the prevalence of known and newly detected autoimmune disease in clinical islet transplant candidates with longstanding T1DM and severe hypoglycaemia and/or glycaemic lability who are routinely screened for coexisting autoimmune disease. METHODS: One hundred and twenty-four C-peptide negative T1DM subjects [77 (62%) female, mean age 44 +/- 9 years, diabetes duration 28 +/- 11 years, body mass index 24.9 +/- 3.5 kg/m(2)] with indications for clinical islet transplantation at the University of Alberta were screened for autoimmune disease by history and measurement of anti-transglutaminase antibodies (positive > 10 U/ml), 09.00 h cortisol (followed by adrenocorticotrophic hormone-stimulation if < 495 nmol/l) and thyroid-stimulating hormone to determine the prevalence of coeliac disease, Addison's disease and autoimmune thyroid disease, respectively. RESULTS: Forty per cent of subjects had one or more coexisting autoimmune disease. The prevalence of autoimmune disease was 35%, coeliac disease 8% and Addison's disease 1.6%. In 11 individuals (9%), one or more autoimmune disease were newly detected (seven coeliac disease and five thyroid disease). Seven of 10 cases of coeliac disease were newly detected. A gluten-free diet in individuals with newly diagnosed coeliac disease reduced gastrointestinal symptoms, but indications for clinical islet cell transplantation persisted. CONCLUSIONS: Coexisting autoimmune disease is common in candidates for clinical islet cell transplantation. Screening in this group identified a substantial number of previously unrecognized cases. Clinicians should consider the presence of autoimmune disease even in the absence of classical symptoms.

Collaboration between nurse educators in Australia and New Zealand extends educational opportunities for nurses

This paper presents a case study style report of a collaborative endeavour between nursing faculty in two institutions, one in New Zealand and the other in Australia. Expertise developed and tested in New Zealand, in teaching through the distance education mode and in the subject area of nursing theory, was able to be applied to assist with establishing a new nursing education programme in Australia. What might have been treated simply as a consultancy situation had greater mutual benefit for all those concerned because of being approached within a collaborative framework. The purpose, process, pitfalls and rewards of the association are described with the hope that others may be stimulated to seek opportunities nationally, and internationally, for pooling resources in the interests of improving the quality and availability of advanced education in nursing.     

Control of intraocular pressure after cataract extraction

We carried out a prospective randomized study in 172 patients undergoing cataract extraction and lens implantation to compare the effects of pilocarpine gel, 1% acetylcholine chloride and 0.01% carbachol on early postoperative intraocular pressure (IOP), to determine the effect of sodium hyaluronate on IOP and to compare the effects of 0.01% carbachol (full-strength) and 0.005% carbachol (half-strength) on IOP, pupil size and brow ache. IOP was measured 3, 6, 9 and 24 hours after surgery, and in the full- and half-strength carbachol groups pupil size and subjective complaints of brow ache were recorded. The mean IOP 3 and 6 hours after surgery was significantly lower in all the treatment groups than in the control groups. At 9 and 24 hours it was significantly lower only in the carbachol groups. The use of sodium hyaluronate was not found to affect the postoperative IOP. There was no difference in postoperative IOP or miosis between the full- and half-strength carbachol groups, but fewer patients in the half-strength group than in the full-strength group reported brow ache at 9 and 24 hours. The results suggest that carbachol is the most effective agent currently available for the management of IOP after cataract extraction.     

The Dartmouth Health Promotion Study: A Failed Quest for Synergy in School Health Promotion

ABSTRACT: The Dartmouth Health Promotion Study was a longitudinal, quasi-experimental field study with a qualitative research arm, designed to learn whether coordinating school health instruction, health services, and a healthful environment enhanced the program's effect on the heart health and mental health of children. The research strategy — the Coordinated Approach — was applied to approximately 300 children in each of two cohorts in grades four to six attending nine trial schools; a further 600 children attended 10 comparison schools in Dartmouth and nine distal comparison schools. Although the qualitative analysis demonstrated that positive feelings were engendered in most areas of the study, when either the classroom or the individual was used as the unit of analysis, the Coordinated Approach did not have a more favorable effect on the heart or mental health of children than did the standard school health program. Thus, the effect of an existing school health program was not directly enhanced through coordinating its components.
