Open access gastroscopy--3 year experience of a new service

We have audited the first 3 yr of a new open access gastroscopy service in the Royal Victoria Hospital, Belfast to assess service demands, patient demography and diagnostic trends. Over 3 yr there were 1872 referrals (800 from fundholding general practitioners), 8.8 per cent were non attenders and 5.4 per cent cancelled appointments. Endoscopic diagnostic categories showed no significant change over the 3 yr, 39 per cent non ulcer dyspepsia, 35 per cent gastro-oesophageal reflux disease (GORD), 17 per cent peptic ulcer disease (PUD), 6 per cent GORD and PUD, 1 per cent gastric erosions and 0.8 per cent carcinoma.

General practitioners' habits and knowledge in relation to the management of H. pylori-associated dyspepsia and their views about a locally available 13-carbon urea breath test

We report the results of general practitioners' views on Helicobacter pylori-associated dyspepsia and use of screening tests in the community. The use of office serology tests in screening is of concern as independent validation in specialist units has been disappointing.

The mechanical and rheological characterisation of implantable medical devices formulated from binary mixtures of cellulose derivatives

This study highlights the potential associated with utilising multi-component polymeric gels to formulate materials that possess unique rheological and mechanical properties. The synergistic effect* and interaction between hydroxyethylcellulose (HEC) and sodium carboxymethylcellulose (NaCMC), polymers which are commonly employed as drug delivery platforms for implantable medical devices (1), have been determined using dynamic, continuous shear and texture profile analysis. * The difference between the actual response of a binary mixture and the sum of the two components comprising the mixture Increases in polymer concentration resulted in an increase in G', G? and ?' whereas tan d decreased. Similarly, significant increases were also apparent in continuous shear and texture analysis. All binary mixtures showed positive synergy values which may suggest associative interaction between the two components.

General practitioner deprivation payments in Northern Ireland:is the current system equitable?

The allocation of General practitioners deprivation payments has been a contentious issue since it was first proposed. This paper examines the method of allocation of such payments in Northern Ireland. A more equitable system would be based on enumeration districts, have a lower Jarman score and a closer relationship between Jarman score and remuneration. Unlike other parts of the UK these changes are now possible in Northern Ireland and should be implemented.
