Diabetic ketoacidosis (DKA) is a common diabetic emergency often managed by general physicians. However, in contrast to its management in children, there was no national guideline/protocol for adults until the recent national protocol was issued for use throughout Scotland. This national protocol was developed from the audit activity described in this article. A prospective audit of the management of DKA and local protocol adherence was carried out at Raigmore Hospital, Inverness (April 2000 to March 2001). This showed deficiencies in the management of DKA with delay in intravenous fluid and insulin administration, and laboratory monitoring being undertaken less frequently than recommended by local guidelines. In addition, 14 DKA management protocols from 17 Scottish trusts were reviewed. The rate and volume of fluid replacement varied slightly between the trusts. There was general agreement within protocols on laboratory monitoring, potassium replacement, insulin administration and bicarbonate usage. The audit showed that there was scope for improvement in the management of DKA and that there were sufficient similarities in protocols used throughout Scotland to allow collaboration on a national protocol. It is anticipated that this will serve to enhance the profile of guidelines and facilitate standardisation and therefore improvement in patient care. Copyright © 2007 John Wiley & Sons.

If the NICE guidance on chest pain of recent onset had been implemented in our study population, the need for change of the offer of specific first line tests (as discussed above) means that, a major re-organisation in both the services in RACPCs and the current process of referral to these specialists cardiac services from the primary care physicians will be required. Whilst acknowledging that regional variations may exist in the proportions of tests needed (depending on the incidence and prevalence of CAD and risk factors), these figures from our study represent a much higher level of need of these specialist tests for patients attending RACPCs than initially suggested by contemporary reviews. We therefore conclude that data from larger studies in many regions may be useful for understanding the degree of regional and national changes required for organising the structure and referrals to specialist cardiac services in Scotland, if an equitable service based on NICE guidance 95 is rolled out throughout United Kingdom in future.

Whilst 20-55% of patients with a diagnosis of Whipple's disease have clinically evident cardiac manifestations, 4 in very few reported cases has the initial presentation been valvular heart disease. 5,6 Paravalvular abscess formation, seen in the present case, does not seem to have been reported in Whipple's endocarditis. Once diagnosed, Whipple's disease can be successfully treated with 1-2 years of agents such as cotrimoxazole.

The causal organism in Whipple's disease, a rare disorder with characteristic duodenal and jejunal changes, was first cultured in 2000. 1 Although cardiac involvement is common in Whipple's, it is seldom an isolated finding.
