Rapid serological diagnosis of Helicobacter pylori:a need for caution and re-evaluation

Screening for Helicobacter pylori in dyspeptic patients may improve selectivity for gastroscopy. Rapid serological tests based on ELISA technique are cheap, readily available and simple to use in the clinical setting. However local evaluation is essential in order to validate these techniques. Fifty-six dyspeptic patients (aged less than 45 yr) had a rapid serological test (Helisal) performed prior to gastroscopy. At gastroscopy H. pylori status was assessed using culture and histology. The Helisal sensitivity was 80 per cent, specificity 82 per cent. Screening patients with the Helisal test would have missed 6 patients with peptic ulcer disease and 2 with oesophagitis. The Helisal test did not perform satisfactorily as a screening test in selection of patients for gastroscopy.

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.

An audit of hospital admissions for acute upper gastrointestinal haemorrhage

A retrospective survey was made of all 189 patients admitted with acute upper gastrointestinal haemorrhage to the Belfast City Hospital in one year. The commonest single reason for admission was peptic ulcer disease, but this was lower than in other published series from the United Kingdom. Overall mortality was 4.8%. The majority of patients did not require either blood transfusion or surgery. There may be potential benefits of endoscopic haemostatic techniques to deal with this condition.

Compression therapy in leg ulcer management

Led ulcer management is an important consideration for all nurses involved in the care of older people. Non-specialists in tissue viability might not always be aware of the evidence base for best practice. The authors examine the effectiveness of multi-layer and single-layer long or short stretch bandage systems in leg ulcer management.

Recurrent lower gastrointestinal bleeding secondary to cytomegalovirus-associated colonic ulcer in a non human immunodeficiency virus infected patient:Timely diagnosis and treatment averted surgery

Mr C, a 68-year-old Chinese male with diabetes mellitus, previous stroke and ischaemic cardiomyopathy on clopidogrel, presented with haematochezia. Colonoscopy showed a sigmoid ulcer, which was treated endoscopically. Histology of the biopsy from the ulcer revealed non-specific changes. However, he presented with recurrent bleeding from this non-healing sigmoid ulcer. A review of the histologic specimen revealed CMV intranuclear inclusion bodies. He was treated with intravenous ganciclovir, with no further hematochezia.

A prospective randomised trial of a "test and treat" policy versus endoscopy based management in young Helicobacter pylori positive patients with ulcer-like dyspepsia, referred to a hospital clinic

Management of dyspepsia remains a controversial area. Although the European Helicobacter pylori study group has advised empirical eradication therapy without oesophagogastroduodenoscopy (OGD) in young H pylori positive dyspeptic patients who do not exhibit alarm symptoms, this strategy has not been subjected to clinical trial.

Wound and skin team. Impact on pressure ulcer prevalence in chronic care.

1. Decreasing the prevalence of pressure ulcers in a chronic care hospital presents a challenge to care providers. 2. The promotion of staff nurses as educational resources has a positive effect on their participation in a wound and skin care team. 3. When basic prevention practices are not in place, risk factors are less useful indicators to predict the development of pressure ulcers. 4. Educating nurses about pressure ulcer etiology, prevention strategies, and treatments has a positive impact on reducing the number of patients who develop pressure ulcers and the number of pressure ulcers that develop on patients in a chronic care hospital.

Fermentation of heated gluten systems by gut microflora

The Maillard reaction causes changes to protein structure and occurs in foods mainly during thermal treatment. Melanoidins, the final products of the Maillard reaction, may enter the gastrointestinal tract, which is populated by different species of bacteria. In this study, melanoidins were prepared from gluten and glucose. Their effect on the growth of faecal bacteria was determined in culture with genotype and phenotype probes to identify the different species involved. Analysis of peptic and tryptic digests showed that low molecular mass products are formed from the degradation of melanoidins. Results showed a change in the growth of bacteria. This in vitro study demonstrated that melanoidins, prepared from gluten and glucose, affect the growth of the gut microflora.

Delayed post-surgical development of dural arteriovenous fistula after cervical meningocele repair

A 34-year-old female patient presented with an intracranial subarachnoid hemorrhage and was found to have a dural arteriovenous fistula at the site of previous cervical meningocele repair. Subsequent occlusion was achieved with endovascular embolization. To our knowledge, the phenomenon of the development of a spinal dural fistula at the site of a meningocele repair has not been recorded before.
