A prospective study of colposcopy in women with mild dyskaryosis or koilocytosis

Summary. Colposcopy was performed in 91 women who had cervical cytology suggesting mild dyskaryosis or showing koilocytosis, all previous cytology having been normal. The final histological diagnosis was C1N III in 22%, CINII in 18%, CINI in 31%, koilocytosis alone in 14% and no abnormality in 15%. These results indicate that even with mild cytological atypia, a high proportion of patients will have more advanced disease when colposcopy-directed punch biopsy is performed.     

Vaginal cones: a conservative method of treating genuine stress incontinence

Summary. A set of weighted vaginal cones designed to exercise the pelvic floor muscles was used by a group of 39 premenopausal patients with genuine stress incontinence who were awaiting corrective surgery. The effectiveness of the exercises in reducing urinary loss was assessed with a standard urine pad test before and after 1 month of training. Of the 30 women who completed 1 month of the exercises 70% felt they were improved or cured and 90% found it an acceptable method of treatment. Of the 30 women only 11 (37%) opted for surgery after training. There was a highly significant correlation (P<0·001, r_s= -0·21) between decreased urine loss and increase in retained cone weight.     

Tympanosclerosis of the stapes: hearing results for various surgical treatments.

When tympanosclerosis involves the tympanic membrane or the lateral ossicles, treatment is usually straightforward and uncomplicated. When the stapes is involved, therapy is more controversial and may be more difficult. We report our results in 154 patients who underwent different surgical procedures for tympanosclerosis of the stapes. Followup was up to 10 years. Pure-tone average threshold was significantly improved (p < 0.05) in patients who underwent mobilization procedures or stapedectomy for definitive treatment. The air-bone gap was less than 20 dB at 6 months postoperative in 72% of patients and less than 30 dB in 90%. At 6 months, 2 years, and 5 years there were no statistically significant differences in hearing results between stapedectomy and mobilization patients, some of whom were followed for up to 10 years. No patient had a profound hearing loss after surgery. Surgical treatment for tympanosclerosis of the stapes is a safe procedure, with hearing results similar to those of surgery for other chronic ear diseases involving the ossicular chain.     

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.
