BACKGROUND: Patients of GPs who have access to community hospitals (CHs) as well as district general hospitals (DGHs) tend to spend on average more days in hospital each year. Increasing attention is being paid to the efficient management of medical admissions; however, there has been no previous prospective study investigating the appropriateness of CH admissions. AIM: To develop a protocol to assess the clinical appropriateness of admission and length of stay of patients in CHs and to simultaneously compare the appropriateness of admissions to all DGHs and CHs in the county. DESIGN OF STUDY: A protocol named Community Hospital Appropriateness Evaluation Protocol (CHAEP) was developed to assess CH admissions through a process of consultation and a series of pilot studies. The appropriateness evaluation protocol (AEP) was also reviewed and used to assess DGH admissions. SETTING: A prospective cohort of 440 DGH admissions from five DGH sites and 440 CH admissions from nine CHs. METHODS: The admissions were assessed and followed for 28 days. If an admission failed to satisfy any of the criteria then the researcher interviewed the clinician to decide whether it was justified to override the protocol and still classify the admission as appropriate. To assess validity, a proportion of these 'clinical overrides' and the researcher's classifications were reviewed retrospectively by a clinical panel. The kappa statistic was used to assess the level of agreement. RESULTS: Applying the CHAEP, 82% of CH admissions satisfied a criterion for admission and a further 3% were given clinical overrides. A lower intensity of care was required for the majority of the remainder while three admissions required DGH care according to AEP criteria. Sixty-eight per cent of bed days satisfied day-of-care criteria within CHAEP and only a further 2% were given clinical override. These results were similar to those found with the AEP at the DGHs where 75% of admissions (plus 16% given clinical override) and 55% of days-of-care (plus 20% given clinical override) satisfied the AEP criteria. The review panel generally did not agree with the clinician's use of the clinical override at the CHs. Agreement between research nurse and review panel was better for the AEP and DGH (kappa = 0.9, 95% confidence interval (CI) = 0.7-1.0) than for the CHAEP and CH (kappa = 0.37, 95% CI = 0.1-0.8). CONCLUSIONS: The CHAEP could be used to audit the appropriateness of admission and length of stay in CHs. Other health communities would need to review the CHAEP before it could be applied within their context.

Ambulatory pH monitoring of the esophagus is carried out by positioning a pH sensor 5 cm above the lower esophageal sphincter (LES). There are several techniques to locate the LES, and each method has a different margin of error. This work used dual pH sensors to monitor simultaneously at two different levels (5 and 10 cm above the LES) in order to establish the possible magnitude of error that could arise from inaccurate placement of a pH probe. Thirty-four patients with symptoms of gastroesophageal reflux (GER) were studied. They were grouped as 20 patients with pathological reflux (GER group) and 14 patients with physiological reflux, based on a reflux score derived by Johnson and DeMeester for distal esophageal pH monitoring. When the reflux scores were compared, the difference between the two monitoring levels was statistically significant in the GER group (p < 0.001) but not in the physiological reflux group (p = 0.09). In the GER group, the difference in the Johnson and DeMeester score accounted for a change in clinical diagnosis in nine of the 20 patients if the pH probe was placed at 10 cm above the upper margin of LES. Proximal reflux episodes (10 cm above LES) were preceded by distal reflux episodes (5 cm above LES) in 97% (878/901) of cases. Accurate probe placement is essential in the diagnosis of GER.

Of 1200 patients referred to the esophageal laboratory at Guy's Hospital for investigation of suspected esophageal motility disorders, 61 (5.1%) were diagnosed as diffuse esophageal spasm. Twenty of these patients whose symptoms were severe did not respond to conservative treatment and were treated by balloon dilatation. Results were good in 14 and poor in six patients, which included one esophageal perforation. Diffuse esophageal spasm was diagnosed where more than 30% nonperistaltic activity was demonstrated by manometry. Lower esophageal sphincter pressure and relaxation were normal in all cases except one. Gastroesophageal reflux was present in four of five poor responders who were examined by 24-h ambulatory pH monitoring, and in only one of 10 good responders. Three of the six patients in whom balloon dilatation was successful proceeded to full-length myotomy, with relief of symptoms in two. The indications for, and results of, balloon dilatation in this condition are discussed, and a new radiological sign is described.

Criteria for diffuse oesophageal spasm(DOS) are dysphagia and chest pain with oesophageal manometry showing retention of peristalsis with the presence of synchronous contractions in response to wet swallows. Because of the intermittent nature of the symptoms, edrophonium was used as a provocative agent to increase diagnostic yield. Three hundred and ninety-six patients underwent transnasal manometry using a Gaeltec system of six internal transducers arranged at 5 cm intervals from the catheter tip; the majority of these patients received 10 mg edrophonium as an intravenous bolus. Reproduction of symptoms with typical manometry of DOS indicated a positive provocation test. There were no significant side effects. DOS was diagnosed in 34 patients who had either the typical manometry or a positive provocation test. Thirty of these patients received edrophonium. Twenty patients had baseline manometry which was diagnostic and ten of this group had a positive provocation test. The remaining 10 patients, who had normal baseline manometry, had positive provocation tests following the injection of edrophonium. Without edrophonium provocation testing, about a third of patients would not have been diagnosed as having DOS.

We report a case of aorto-left renal vein fistula secondary to an aortic aneurysm presenting with flank pain, a left-sided varicocoele and microscopic haematuria. These symptoms and signs should alert the clinician to this rare complication of abdominal aortic aneurysm.

The reactivities of Ca1 and HMFG2 monoclonal antibodies were compared on paraffin wax embedded breast tissues using indirect immunoperoxidase. The expression of Ca antigen, like HMFG2, is not exclusive to malignancy: Ca was present in 41/53 (77%) and HMFG2 in 42/53 (79.2%) non-malignant conditions and both were present in 33/35 (94%) carcinomas. Similar results were obtained when cryostat sections were used. Both antigens showed striking similarities in their topographical distributions, although quantitative differences were seen. Their cellular and sub-cellular localisations were investigated by double labelling immunofluorescence and immunogold electron microscopy, which showed that the expression of Ca and HMFG2 antigens was closely associated on cell membranes but that the epitopes were distinct.
