Abstract
Purpose Berry-derived phenolic compounds found in grapes have been associated with a number of health benefits, including the augmentation of human brain function and cognition. Previous intervention studies of Concord grape juice have demonstrated improvement to memory and driving ability following 3- to 4-month supplementation in middle-aged and older adults. However, no studies to date have demonstrated acute cognitive benefits of grape juice, and investigation of these effects in young adults is lacking. Methods This randomised, placebo-controlled, double-blind, counterbalanced-crossover study, assessed the effects of 230 ml purple grape juice or sugar-matched control in 20 healthy young adults. Computerised measures of episodic memory, working memory, attention and mood were completed at baseline and following a 20-min absorption period. Results Purple grape juice significantly improved reaction time on a composite attention measure (p = 0.047) and increased calm ratings (p = 0.046) when compared to placebo. Order effects also indicated an enduring positive effect on pre-dose memory reaction time (p = 0.018) and post-dose calm ratings (p = 0.019) when purple grape was consumed first. Conclusions These findings in a small sample of healthy young adults suggest that purple grape juice can acutely enhance aspects of cognition and mood. No significant effects of juice were observed on memory measures, suggesting that these may be less susceptible to manipulation following acute supplementation in healthy young adults. Potential mechanisms underlying these effects include modulation of cerebral blood flow, glucoregulation and inhibition of monoamine oxidase activity, all of which require further exploration.

Abstract
BACKGROUND Variceal bleeding is an acute medical emergency with high mortality. Although less common than oesophageal variceal haemorrhage, gastric variceal bleeding is more severe and more difficult to control. The optimal therapy for gastric variceal bleeding remains unclear although endoscopic injection of N-Butyl-2-Cyanoacrylate (Histoacryl) glue is often used. However, its long-term efficacy is poorly described. We studied the immediate and long-term effects of Histoacryl glue injection as treatment for bleeding gastric varices in a large UK hospital. METHOD Endoscopy records and case notes were used to identify patients receiving Histoacryl injection for gastric variceal bleeding over a 4-year period. RESULTS Thirty-one patients received Histoacryl for gastric variceal bleeding. Seventy-four per cent patients had alcohol-related liver disease and 61% of cirrhotics were Childs Pugh grade B or C. Fifty-eight per cent were actively bleeding during the procedure with 100% haemostasis rates achieved. Two patients developed pyrexia within 24 h of injection settling with antibiotics. No other complications were encountered. Mean overall follow-up was 35 months, with mean follow-up of survivors 57 months. Forty-eight per cent patients had endoscopic ultrasound assessment of varices during follow-up with no effect on rebleeding rates. Thirteen per cent required subsequent transjugular intrahepatic portosystemic shunt placement. Gastric variceal rebleeding rate was 10% at 1 year and 16% in total. One- and two-year mortality was 23% and 35%, respectively. CONCLUSION Endoscopic injection of Histoacryl glue appears to be a safe and effective treatment for gastric variceal bleeding. Further data are required to compare it with other therapies in this situation.

Abstract
BACKGROUND AND AIM Endoscopic Ultrasound (EUS) has increased the staging accuracy of oesophageal cancer. The addition of EUS guided fine needle aspiration (EUS-FNA) appears superior to standard EUS for nodal staging. Our aim was to study the impact of EUS-FNA in the management of patients with oesophageal cancer. METHODS We studied patients undergoing EUS for this indication between May 2003 and May 2006. EUS was performed in patients who were candidates for radical therapy following CT scanning. If suspicious non-peritumoural nodes were seen on EUS, EUS-FNA was undertaken. Further staging was performed as appropriate and all cases were discussed at our multidisciplinary meeting. Results and decisions were prospectively recorded. RESULTS One hundred and ninety one patients underwent EUS for staging of oesophageal cancer during this period and 44 EUS-FNA were performed in 42 patients (mean age 62.2 years). Sixty two per cent of patients had adenocarcinoma and 48% sampled nodes were <10 mm diameter. Overall, 48% nodes were positive and two "suspicious" for malignancy. Following a positive EUS-FNA and MDM discussions, 15 patients had palliative and two neoadjuvant therapy. Eleven patients with a negative EUS-FNA underwent radical therapy. Therefore, EUS-FNA appeared to alter management in 28 (67%) patients. CONCLUSION EUS-FNA appears to help direct patients towards appropriate treatment strategies.

Abstract
Drug addiction is a state of altered brain reward and self-regulation mediated by both neurotransmitter and hormonal systems. Although an organism's internal system attempts to maintain homeostasis when challenged by exogenous opiates and other drugs of abuse, it eventually fails, resulting in the transition from drug use to drug abuse. We propose that the attempted maintenance of hormonal homeostasis is achieved, in part, through alterations in levels of processing enzymes that control the ratio of active hormone to pro-hormone. Two pro-hormone convertases, PC1/3 and PC2 are believed to be responsible for the activation of many neurohormones and expression of these enzymes is dependent on the presence of a cyclic-AMP response element (CRE) in their promoters. Therefore, we studied the effects of short-term (24-h) and long-term (7-day) morphine treatment on the expression of hypothalamic PC1/3 and PC2 and levels of phosphorylated cyclic-AMP-response element binding protein (P-CREB). While short-term morphine exposure down-regulated, long-term morphine exposure up-regulated P-CREB, PC1/3 and PC2 protein levels in the rat hypothalamus as determined by Western blot analysis. Quantitative immunofluorescence studies confirmed these regulatory actions of morphine in the paraventricular and dorsomedial nucleus of the hypothalamus. Specific radioimmunoassays demonstrated that the increase in PC1/3 and PC2 levels following long-term morphine led to increased TRH biosynthesis as evidence by increased TRH/5.4 kDa C-terminal proTRH-derived peptide ratios in the median eminence. Promoter activity experiments in rat somatomammotrope GH3 cells containing the mu-opioid receptor demonstrated that the CRE(s) in the promoter of PC1/3 and PC2 is required for morphine-induced regulation of PC1/3 and PC2. Our data suggest that the regulation of the prohormone processing system by morphine may lead to alterations in the levels of multiple bioactive hormones and may be a compensatory mechanism whereby the organism tries to restore its homeostatic hormonal milieu. The down-regulation of PC1/3, PC2 and P-CREB by short-term morphine and up-regulation by long-term morphine treatment may be a signal mediating the switch from drug use to drug abuse.

Abstract
It remains unclear whether any aspect of quality of life has a role in predicting survival in an unselected cohort of patients with gastro-oesophageal cancer. Therefore the aim of the present study was to examine the relationship between quality of life (EORTC QLQ-C30), clinico-pathological characteristics and survival in patients with gastro-oesophageal cancer. Patients presenting with gastric or oesophageal cancer, staged using the UICC tumour node metastasis (TNM) classification and who received either potentially curative surgery or palliative treatment between November 1997 and December 2002 (n=152) participated in a quality of life study, using the EORTC QLQ-C30 core questionnaire. On univariate analysis, age (P<0.01), tumour length (P<0.0001), TNM stage (P<0.0001), weight loss (P<0.0001), dysphagia score (P<0.001), performance status (P<0.1) and treatment (P<0.0001) were significantly associated with cancer-specific survival. EORTC QLQ-C30, physical functioning (P<0.0001), role functioning (P<0.001), cognitive functioning (P<0.01), social functioning (P<0.0001), global quality of life (P<0.0001), fatigue (P<0.0001), nausea/vomiting (P<0.01), pain (P<0.001), dyspnoea (P<0.0001), appetite loss (P<0.0001) and constipation (P<0.05) were also significantly associated with cancer-specific survival. On multivariate survival analysis, tumour stage (P<0.0001), treatment (P<0.001) and appetite loss (P<0.0001) were significant independent predictors of cancer-specific survival. The present study highlights the importance of quality of life (EORTC QLQ-C30) measures, in particular appetite loss, as a prognostic factor in these patients.

Abstract
Habitat and biodiversity differences between matched pairs of organic and non-organic farms containing cereal crops in lowland England were assessed by a large-scale study of plants, invertebrates, birds and bats. Habitat extent, composition and management on organic farms was likely to favour higher levels of biodiversity and indeed organic farms tended to support higher numbers of species and overall abundance across most taxa. However, the magnitude of the response varied; plants showed larger and more consistent responses than other taxa. Variation in response across taxa may be partly a consequence of the small size and isolated context of many organic farms. Extension of organic farming could contribute to the restoration of biodiversity in agricultural landscapes.

Abstract
The Farm Scale Evaluations (FSEs) showed that genetically modified herbicide-tolerant (GMHT) cropping systems could influence farmland biodiversity because of their effects on weed biomass and seed production. Recently published results for winter oilseed rape showed that a switch to GMHT crops significantly affected weed seedbanks for at least 2 years after the crops were sown, potentially causing longer-term effects on other taxa. Here, we seek evidence for similar medium-term effects on weed seedbanks following spring-sown GMHT crops, using newly available data from the FSEs. Weed seedbanks following GMHT maize were significantly higher than following conventional varieties for both the first and second years, while by contrast, seedbanks following GMHT spring oilseed rape were significantly lower over this period. Seedbanks following GMHT beet were smaller than following conventional crops in the first year after the crops had been sown, but this difference was much reduced by the second year for reasons that are not clear. These new data provide important empirical evidence for longer-term effects of GMHT cropping on farmland biodiversity.

Abstract
There is increasing evidence that the presence of an ongoing systemic inflammatory response is associated with poor outcome in patients undergoing resection for a variety of tumours. The aim of the present study was to examine the relationship between clinico-pathological status, preoperative C-reactive protein concentration and cancer-specific survival in patients undergoing resection for gastro-oesophageal cancer. One hundred and twenty patients attending the upper gastrointestinal surgical unit in the Royal Infirmary, Glasgow, who were selected for potentially curative surgery, were included in the study. Laboratory measurements of haemoglobin, white cell, lymphocyte and platelet counts, albumin and C-reactive protein were carried out at the time of diagnosis. All patients underwent en-bloc resection with lymphadenectomy and survived at least 30 days following surgery. On multivariate analysis, only the positive to total lymph node ratio (hazard ratio (HR) 2.02, 95% confidence interval (CI) 1.44–2.84, P<0.001) and preoperative C-reactive protein concentration (HR 3.53, 95% CI 1.88–6.64, P<0.001) were independent predictors of cancer-specific survival. The patient group with no evidence of a preoperative systemic inflammatory response (C-reactive protein ⩽10 mg l−1) had a median survival of 79 months compared with 19 months in the elevated systemic inflammatory response group (P<0.001). The results of the present study indicate that in patients selected to undergo potentially curative resection for gastro-oesophageal cancer, the presence of an elevated preoperative C-reactive protein concentration is an independent predictor of poor cancer-specific survival.

Abstract
There is increasing evidence that the presence of an ongoing systemic inflammatory response is associated with poor outcome in patients with advanced cancer. The aim of the present study was to examine whether an inflammation-based prognostic score (Glasgow Prognostic score, GPS) was associated with survival, in patients with inoperable gastro-oesophageal cancer. Patients diagnosed with inoperable gastro-oesophageal carcinoma and who had measurement of albumin and C-reactive protein concentrations, at the time of diagnosis, were studied (n=258). Clinical information was obtained from a gastro-oesophageal cancer database and analysis of the case notes. Patients with both an elevated C-reactive protein (>10 mg l(-1)) and hypoalbuminaemia (<35 g l(-1)) were allocated a GPS score of 2. Patients in whom only one of these biochemical abnormalities was present were allocated a GPS score of 1, and patients with a normal C-reactive protein and albumin were allocated a score of 0. On multivariate survival analysis, age (hazard ratio (HR) 1.22, 95% CI 1.02-1.46, P<0.05), stage (HR 1.55, 95% CI 1.30-1.83, P<0.001), the GPS (HR 1.51, 95% CI 1.22-1.86, P<0.001) and treatment (HR 2.53, 95% CI 1.80-3.56, P<0.001) were significant independent predictors of cancer survival. A 12-month cancer-specific survival in patients with stage I/II disease receiving active treatment was 67 and 60% for a GPS of 0 and 1, respectively. For stage III/IV disease, 12 months cancer-specific survival was 57, 25 and 12% for a GPS of 0, 1 and 2, respectively. In the present study, the GPS predicted cancer-specific survival, independent of stage and treatment received, in patients with inoperable gastro-oesophageal cancer. Moreover, the GPS may be used in combination with conventional staging techniques to improve the prediction of survival in patients with inoperable gastro-oesophageal cancer.

Abstract
The most common type of esophageal dysfunction associated with chest pain is gastroesophageal reflux, which may be induced by exercise. The effect of exercise on esophageal function has mainly been investigated in normal subjects or trained athletes. Few studies have investigated exercise and esophageal motility disorders. One hundred and thirty-five patients underwent ambulatory esophageal manometry and pH monitoring, before, during and immediately after moderate exercise. Patients were divided into four groups: Normal, nutcracker, diffuse spasm and gastroesophageal reflux disease (GERD). Ambulatory manometry and pH were monitored while exercising on a treadmill during which standardized boluses of water were administered. Nutcracker and diffuse spasm patients demonstrated a significant fall in esophageal wave amplitude during exercise compared to controls, which returned rapidly to pre exercise values after resting. There was no evidence of acid reflux in the non-reflux groups during exercise. Reflux was noted in 13 patients with GERD during exercise, none of whom had evidence of reflux at the onset of exercise. When these patients were classified by reflux type, the majority, 11 patients, were found to come from the combined or supine reflux group. Esophageal amplitude in nutcracker esophagus does not increase during moderate exercise. Moderate exercise provokes reflux in GERD patients with combined or supine reflux.

Abstract
AIMS Intestinal metaplasia and gastro-oesophageal reflux disease typify classical Barrett's oesophagus. Cytokeratin (CK) 7 and 20 phenotypes differentiate intestinal metaplasia in long segment Barrett's oesophagus from gastric intestinal metaplasia. This study examines the relationship between CK7/20 phenotypes and reflux disease in intestinal metaplasia of the distal oesophagus. METHODS AND RESULTS Eighty patients with oesophageal pH studies included 30 with long segment Barrett's, 16 with short segment Barrett's and 34 with intestinal meatplasia of the gastro-oesophageal junction. Representative biopsy specimens were immunostained for CK7 and CK20. All 30 long segment patients demonstrated a Barrett's CK7/20 phenotype. All nine short segment patients with gastro-oesophageal reflux had a Barrett's CK7/20 phenotype, while four of seven short segment patients without reflux had a gastric CK7/20 phenotype (P = 0.019). Of 14 patients with intestinal metaplasia of the gastro-oesophageal junction and reflux, 10 (71%) had a Barrett's CK7/20 phenotype, compared with 11 (55%) of the 20 non-reflux patients. CONCLUSIONS CK7/20 immunoreactivity for patients with intestinal metaplasia of the distal oesophagus without long segment Barrett's oesophagus suggests a heterogeneous group, with an association between Barrett's CK7/20 pattern and gastro-oesophageal reflux disease in both short segment Barrett's and intestinal metaplasia of the gastro-oesophageal junction.

Abstract
Field boundaries are man-made features found worldwide and their multiple functions in agricultural landscapes are now widely recognised. These landscape features have declined drastically in many developed countries as a result of agricultural intensification. In Great Britain, field boundaries are regarded as elements of particular significance in the countryside, both in term of extent and value, whether ecological, cultural, or aesthetic. The Countryside Surveys of Great Britain, a national ecological, surveillance programme initiated in the late 1970s, provides information about the change in extent and ecological condition of field boundaries. In this paper, we present the main results on field boundaries derived from the latest survey, Countryside Survey 2000. These include stock and change of boundaries for the 1990-1998 period as well as an update of the previously published 1984-1990 data. Special attention is given to the evolution of the length of hedges. Applicability of the Countryside Survey methodology to other monitoring programmes and further use of the data is discussed together with the potential ecological consequences of the changes described in the paper.

Abstract
This randomised, double-blind, placebo-controlled study was designed to evaluate the ability of the orally administered matrix metalloproteinase inhibitor, marimastat, to prolong survival in patients with non-resectable gastric and gastro-oesophageal adenocarcinoma. Three hundred and sixty-nine patients with histological proof of adenocarcinoma, who had received no more than a single regimen of 5-fluorouracil-based chemotherapy, were randomised to receive either marimastat (10 mg b.d.) or placebo. Patients were treated for as long as was tolerable. The primary endpoint was overall survival with secondary endpoints of time to disease progression and quality of life. At the point of protocol-defined study completion (85% mortality in the placebo arm) there was a modest difference in survival in the intention-to-treat population in favour of marimastat (P=0.07 log-rank test, hazard ratio=1.23 (95% confidence interval 0.98-1.55)). This survival benefit was maintained over a further 2 years of follow-up (P=0.024, hazard ratio=1.27 (1.03-1.57)). The median survival was 138 days for placebo and 160 days for marimastat, with 2-year survival of 3% and 9% respectively. A significant survival benefit was identified at study completion in the pre-defined sub-group of 123 patients who had received prior chemotherapy (P=0.045, hazard ratio=1.53 (1.00-2.34)). This benefit increased with 2 years additional follow-up (P=0.006, hazard ratio=1.68 (1.16-2.44)), with 2-year survival of 5% and 18% respectively. Progression-free survival was also significantly longer for patients receiving marimastat compared to placebo (P=0.009, hazard ratio=1.32 (1.07-1.63)). Marimastat treatment was associated with the development of musculoskeletal pain and inflammation. Events of anaemia, abdominal pain, jaundice and weight loss were more common in the placebo arm. This is one of the first demonstrations of a therapeutic benefit for a matrix metalloproteinase inhibitor in cancer patients. The greatest benefit was observed in patients who had previously received chemotherapy. A further randomised study of marimastat in these patients is warranted.

Abstract
Despite being established for the treatment of peptic ulcer (PU) disease, few studies have assessed the long-term effectiveness and economic benefits of Helicobacter pylori (Hp) eradication in primary care. Our aim was to investigate the effect of community based Hp eradication for patients with chronic peptic ulcer disease requiring maintenance acid suppression. The endpoints used were the patients dyspeptic symptoms and the requirement for the prescription of maintenance acid suppression therapy. The study area covered seven general practices in the Glasgow area. Patients with previously diagnosed peptic ulcer disease receiving prescribed acid suppression therapy were invited to a dyspepsia clinic. Hp status was assessed by Helisal rapid blood test (HRBT). Positive patients received Hp eradication therapy and were reviewed six weeks later. At six months a review of practice records was carried out, and two years after eradication a postal questionnaire was sent to participating patients. A total of 243 patients attended the initial clinic of which 81.9% were HRBT positive. 156 of 196 patients offered Hp eradication re-attended at six weeks. The per protocol eradication rate was 91.7%. After six months patients who had received eradication therapy were less likely to require maintenance acid suppression therapy compared with those to whom eradication was not given. Two years after treatment 76.5% of patients felt their symptoms were improved, but 42.2% were still receiving maintenance therapy. The estimated cost of treatment per month per patient had fallen from 20.23 Pounds to 9.39 Pounds after eradication. In conclusion we felt that community based Hp eradication for patients with chronic PU disease is effective, however it does not completely alleviate dyspepsia. Predictors of symptomatic response or of no longer requiring acid suppression therapy after two years were younger age of onset of PU disease and absence of pre-documented gastro-oesophageal reflux disease or hiatus hernia. Hp eradication improves patients symptoms, reduces the requirement for maintenance acid suppression and is cost-effective after two years follow-up in this targeted group.

Abstract
BACKGROUND Minichromosome maintenance (Mcm) proteins are essential for eukaryotic DNA replication, and their expression implies potential for cell proliferation. Expression is dysregulated in dysplastic states but data for oesophageal squamous mucosa and Barrett's mucosa have not been published. AIM To test the hypothesis that Mcm proteins are downregulated together with the proliferation marker Ki-67 in differentiating epithelial compartments of non-dysplastic squamous and Barrett's epithelium, and that this process does not occur in dysplastic mucosae. METHODS AND CASES: Forty five patients with Barrett's oesophagus included 20 with glandular dysplasia (10 low grade, eight high grade, two both, and four with invasive adenocarcinoma). Twenty five other patients included 12 with oesophageal squamous dysplasia (three low grade, six high grade, three both, and four with invasive squamous carcinoma). Formalin fixed paraffin embedded tissue sections from biopsy series and resections were immunostained using antibodies to Mcm2, Mcm5, and Ki-67. Percentage of nuclei positive for Mcm2, Mcm5, and Ki-67 was estimated and scored from 0 to 6 as: 0, none +; 1, <10%+; 2, 10-30%+; 3, 30-70%+; 4, 70-90%+; 5, >90%+; 6, all+. Four separate epithelial strata were scored: in squamous epithelium the basal layer and thirds to the surface, in Barrett's mucosa the luminal surface, upper and lower crypt, and deep glands. RESULTS In non-dysplastic squamous epithelium and Barrett's mucosa, high level expression of Mcm2, Mcm5, and Ki-67 proteins was largely confined to the proliferative compartments and downregulated in differentiated compartments. Expression persisted up to the mucosal surface in dysplastic squamous epithelium and Barrett's mucosa. CONCLUSIONS Persistent expression of Mcm2, Mcm5, and Ki-67 proteins in luminal compartments of dysplastic oesophageal squamous epithelium and dysplastic Barrett's mucosa may be diagnostic markers and imply disruption of cell cycle control and differentiation in these dysplastic epithelia.

Abstract
BACKGROUND Telomerase is detectable in 85% of cancers, but is largely repressed in normal tissues. Human telomerase RNA (hTR) inhibition is a promising anti-cancer strategy, but requires differential expression between malignant and normal tissue. METHOD Archival paraffin sections from 48 oral squamous cell carcinomas (SCC) (23 floor of mouth, 25 tongue) and 56 oesophageal carcinomas (41 SCC, 15 adenocarcinomas) were evaluated for hTR expression using a radiolabelled riboprobe. Results were compared with expression in controls and adjacent histologically normal tissue. Statistical analysis was by the chi2 test. RESULTS hTR was detectable in 76% of oral SCC overall (floor of mouth 65%, tongue 88%, P=0.61), and in 54% of oesophageal cancers (SCC 51%, adenocarcinoma 60%, P=0.56). Detectable hTR expression was significantly more frequent in oral SCC than oesophageal SCC (P=0.01). hTR expression was only detected in normal tissue at low levels in basal squamous epithelium. There was agreement of hTR expression between 8/9 surgically excised carcinomas and their initial diagnostic biopsies. CONCLUSION Tumour-specific hTR expression confirms hTR inhibition as a possible therapeutic strategy in some if not all oesophageal and oral cancers. Generally concordant hTR status between biopsy and resection suggest that biopsy may have a role in selecting candidates for telomerase inhibition therapy.

Abstract
The aim of this study was to evaluate the safety and tolerability of 4 weeks administration of marimastat, and to seek evidence of biological activity as observed by changes in the endoscopic appearance of the gastric tumours. 35 patients with advanced, inoperable gastric or gastro-oesophageal tumours were recruited. The dose of marimastat was reduced from the starting dose of 50 mg twice daily (6 patients) to 25 mg once daily (29 patients). 31 completed the 28 day study period. Marimastat was generally well tolerated, with the principal treatment-related toxicity being pain and stiffness of the musculoskeletal system. These symptoms occurred more frequently at the higher-dose, and increased to involve a total of 13 patients (37%) with longer-term treatment. The events were usually rapidly reversible on drug discontinuation. 3 patients receiving prolonged treatment experienced more severe symptoms, with the development of skin thickening and contractures in the hands. At endoscopy, 10 patients showed an increased fibrotic cover of the tumour, 8 had decreased haemorrhagic appearance, and in at least 2 cases where comparative tumour histology was assessable, there was evidence of increased stromal fibrotic tissue.

Abstract
OBJECTIVE Although the role of Helicobacter pylori in the pathogenesis of peptic ulcer disease and antral gastritis has been well documented, the role of H. pylori in esophageal disease has not been clearly defined. To clarify this issue, we analyzed 141 patients with histologically confirmed esophageal disease. METHODS The study group consisted of 82 patients with Barrett's esophagus, 19 with adenocarcinoma of the esophagus arising in columnar epithelium and 40 patients with reflux esophagitis without columnar metaplasia of the esophagus. In each of these cases the presence or absence of H. pylori was assessed histologically. RESULTS H. pylori was present in 19 of 82 patients (23%) with Barrett's esophagus, but was absent in all patients with adenocarcinoma of the esophagus and in patients with reflux esophagitis without Barrett's metaplasia. H. pylori was found only in areas of gastric type metaplasia in the patients with Barrett's esophagus. All of the 19 Barrett's esophagus group with H. pylori had chronic inflammation, and in 16 the inflammation was severe. H. pylori was significantly associated with severity of inflammation in patients with Barrett's esophagus (p < 0.001). Members of the Barrett's group with evidence of moderate to severe dysplasia were negative for H. pylori. CONCLUSION These data confirm that the presence of gastric type mucosa within the esophagus is a prerequisite for H. pylori colonization, and that H. pylori may contribute to the severity of inflammation in Barrett's epithelium.

Abstract
The aim of this study was to investigate the origin of globus pharyngis with particular reference to esophageal disorders such as gastroesophageal reflux disease (GERD), motility disorders, structural abnormalities, other gastrointestinal tract diseases, and psychological profile. Previous studies on this subject using 24-hour pH monitoring give conflicting results and are hampered by the high background prevalence of asymptomatic GERD in the normal Western population. The local Chinese population is known to have a very low background level of GERD and therefore is an ideal study population. Twenty-six patients with globus pharyngis underwent 24-hour ambulatory pH monitoring, esophageal manometry, and esophagogastroduodenoscopy with lower esophageal biopsy. A control group of 20 patients presenting with non-ulcer dyspepsia was similarly investigated. Personality profiles of the globus pharyngis subjects and an appropriate control group were assessed. Eight of the globus pharyngis group (30.7%) had evidence of GERD, whereas only one of the controls (5%) demonstrated GERD on 24-hour esophageal pH monitoring (P < 0.05). The manometric and personality profile studies did not show significant differences between study and control groups. We concluded that the finding of GERD in patients with globus pharyngis is not a coincidental finding but that there is a true association between GERD and globus pharyngis.

Abstract
BACKGROUND Gastric outlet obstruction secondary to chronic duodenal ulceration is an indication for surgery as conservative management with balloon dilatation frequently fails. The standard operation is truncal vagotomy and a drainage procedure. However, development of minimally invasive surgery has revolutionized the surgical approach to this clinical problem. METHODS Twelve male patients with pyloric stenosis secondary to duodenal ulceration underwent laparoscopic truncal vagotomy and gastrojejunostomy. The perioperative and long term outcome of this group of patients were analyzed. RESULTS The median operating time was 210 (range 180 to 240) minutes. Median postoperative stay was 6 (range 4 to 41) days. Conversion to laparotomy was necessary in one patient. Delayed gastric emptying occurred in two patients but resolved on conservative measures. At a median postoperative followup of 6 (range 1 to 12) months all patients had a good symptomatic outcome (Visick grades I or II). CONCLUSIONS Laparoscopic truncal vagotomy and gastrojejunostomy is a feasible technique. Intermediate followup shows good symptomatic results when used for pyloric stenosis.

Abstract
The introduction of video-assisted surgery has revolutionized thoracic surgery. The main attraction is the avoidance of a large thoracotomy incision and its associated morbidity. We present the case of a 55-year-old woman with an oesophageal diverticulum presenting with troublesome dysphagia. A thoracoscopic assisted oesophageal diverticulectomy was performed. Post-operative recovery was uneventful, and only two doses of intramuscular opiate analgesic were required. The patient remained asymptomatic at a follow-up of 3 months.

Abstract
Attempts to improve the standard of early trauma management through the training and instruction of medical personnel have had variable results. Knowledge of trauma care is inadequate among all grades of medical and paramedical staff, and not much improvement has been made by the availability of instruction courses in trauma management. Staff most likely to attend such courses are seemingly already more proficient than staff who choose not to. To achieve maximum benefit from future courses, therefore, we believe attendance should be compulsory for all personnel involved in acute trauma care.

Abstract
"In spite of extensive literature on migration in the Soviet Union, we know little about household-level decisions. This study specifies and estimates those variables important to understanding the migration decision. Using data from the Soviet Interview Project (SIP), we examine the forces influencing the decision to migrate or not to migrate, and in addition, for those who did migrate, the forces influencing the locational choices made. The results indicate that, while some of the traditional factors influencing migration are important, others are not, suggesting that in the post-Soviet era, differentiating the persistence of Soviet-type forces from emerging market-type forces will be important for an understanding of urban to urban migration."

Abstract
Peroperative antegrade colonic lavage is often performed before primary anastomosis in emergency colonic surgery. The influence of colonic lavage on bacterial translocation from the obstructed colon was determined. Forty female Wistar rats were studied in four groups: (1) control; (2) non-obstructed with lavage; (3) obstructed; and (4) obstructed with lavage. Ligature obstruction of the rectum was performed in groups 3 and 4. Some 4 days later 35S-radiolabelled Escherichia coli was inoculated into the colon of all animals. Groups 2 and 4 underwent colonic lavage. Lavage in the group 4 animals with left-sided colonic obstruction significantly increased the levels of E. coli in regional nodes, liver, spleen, lung, kidney and blood (as assessed by organ culture and scintillation counting) compared with those in groups 1, 2 and 3 (P < 0.05). These results suggest that peroperative lavage of the obstructed colon significantly increases the level of bacterial translocation.

Abstract
A total of 212 consecutive fine-wire localization breast biopsies in 202 patients were performed on impalpable mammographically suspicious lesions. Preoperative fine-needle aspiration cytology was performed on 159 lesions and was valuable in planning the extent of the fine-wire localization biopsy. All 212 target lesions were accurately biopsied during the initial surgery. Overall, 134 lesions were malignant and 78 benign (benign:malignant ratio 1:1.72), with fewer biopsies for benign lesions performed in screened patients (benign:malignant ratio 1:2.43) than in those with symptoms (ratio 1:1). Breast conservation was achieved in 72 patients (80 per cent) with screen-detected in situ or invasive carcinoma and in 19 of 37 presenting via a symptomatic clinic. In 160 of 202 patients (79 per cent) the initial fine-wire localization biopsy was diagnostic and therapeutic.

Abstract
Oesophageal sphincter measurements were carried out on 80 patients using the stationary pull through technique; Normals (n = 21), Nutcracker (n = 12), Refluxers (n = 21), and Barrett's (n = 26). Sphincter pressure (LOSP), abdominal length of sphincter, and overall sphincter length were measured. The Sphincter Function Index (SFI) was calculated as the product of sphincter pressure and percentage sphincter length (AL) exposed to abdominal pressure. Patients also had routine endoscopy and 24 hour pHmetry. SFI values discriminated between all four groups. LOSP was significantly different for Barrett's (p < 0.01) and Nutcracker (p < 0.01) compared to normals. AL was significant for Refluxers (p < 0.001) and Barrett's (p < 0.001) compared to normals. SFI gives better discrimination than LOSP or AL alone and may be useful in evaluating the response to treatment.

Abstract
Acute gastric stress ulceration occurs frequently in severely ill patients. Mucosal ischemia is central to the etiology of stress ulceration. The ability of the mucosa to restore continuity when damaged is one of the most important of the local defence mechanisms against injury. The aims of this study were to investigate this restitutive process during stress ulcer formation and to determine the effect of prophylaxis against stress ulceration on gastric mucosal cell kinetics. Nuclear DNA was radiolabeled in vivo with tritiated thymidine, and after autoradiography the position and number of labeled cells along the gastric mucosal gland were determined. Wistar rats were studied immediately and 48 hr after cold restraint stress. The labeling index in the proliferative zone of the gastric mucosa was significantly suppressed immediately after stress (12.58% vs 16.81% for unstressed controls, P < 0.001). This effect persisted for 48 hr after stress (9.89% vs 16.35% for unstressed controls, P < 0.001). Prophylaxis against stress ulceration with cimetidine or allopurinol prevented this suppression of gastric mucosal cell kinetics and promoted early migration of labeled cells towards the surface of the mucosal gland. Allopurinol prophylaxis was associated with migration of mucosal cells immediately following stress greater than that following cimetidine prophylaxis (14.0% vs 9.3% surface layer labeling index, P < 0.01). Allopurinol, a xanthine oxidase inhibitor, reduces oxygen free radical production during ischemia reperfusion injury. These results emphasise the importance of the gastric mucosal defence mechanisms in protection against injury and indicate the role of ischemia in the aetiology of acute gastric stress ulceration.

Abstract
The influence of stress on the structure of the gastric mucosal capillary network was investigated in an experimental model using scanning electron microscopy (SEM) to study corrosion casts of the gastric microvasculature. An index of microcirculatory patency was devised to improve the objectivity of SEM. Stress (mean score 42.4 +/- 4.7) severely disrupted the structure of the mucosal capillary network when compared with controls (mean 5.0 +/- 2.9) (P < 0.01). Disruption of the microvascular network was significantly reduced by pretreatment with allopurinol, cimetidine, and misoprostol, these groups having mean damage scores of 17.4 +/- 5.8, 21.2 +/- 7.9, and 28.6 +/- 9.3, respectively, when compared with untreated stressed controls in which the mean score was 42.4 +/- 4.7 (P < 0.02). Microvascular disruption is a significant factor in stress ulceration and the efficacy of allopurinol in minimizing the stress-induced disruption of the microvascular network provides further indirect evidence for the role of ischemia and oxygen-derived free radical generation in its etiology.

Abstract
Ambulatory non-perfused oesophageal manometry was used to study oesophageal body function during consumption of a full meal in patients with achalasia. A measure of oesophageal body activity (the meal area index) was developed by calculating the total area under the pressure curve during eating, above the preprandial baseline oesophageal pressure, per meal minute. Untreated patients with achalasia (n = 13) were compared with normal subjects (n = 42), patients with benign stricture (n = 9) and patients with achalasia who had undergone Heller's myotomy (n = 17). The results showed a high meal area index in achalasia, due to a rise in baseline oesophageal pressure and frequent high-amplitude contractions during eating. This was not seen in normal subjects or patients with stricture. The high meal area index was abolished by successful Heller's myotomy but remained in two patients with persisting dysphagia. Sustained high intraoesophageal pressure is generated during consumption of a solid meal in untreated achalasia, resulting in a unique manometric profile. Manometry during eating using the meal area index permits quantitative assessment of oesophageal body function in achalasia and may aid in the assessment of response to treatment.

Abstract
The effects of starch on the development of postoperative adhesions were examined in 144 Sprague Dawley rats. Groups of rats were injected intraperitoneally with suspensions of washings from starched gloves, starch-free gloves and starch-poor washed gloves, and after operative manipulation of the bowel. The incidence of adhesions was greatest (78 per cent) after laparotomy and injections of starch-rich washings and least when starch-poor (33 per cent) or starch-free glove suspensions (37 per cent) were used, confirming an advantage for washing gloves or switching to starch-free products.

Abstract
Acute gastric stress ulceration was induced in rats by cold restraint and was not associated with alteration of gastric pH or serum gastrin level. Cimetidine and oral and intravenous allopurinol were prophylactic but allopurinol was more effective in reducing the depth of the lesion and acted without alteration in gastric pH. The efficacy of allopurinol in preventing stress ulceration offers further indirect evidence of the role of ischaemia and oxygen free radical generation in the aetiology of stress ulceration.

Abstract
Primary motor disorders of the oesophagus have distinct manometric patterns but require full oesophageal investigation to exclude a secondary cause. Myotomy and forceful dilatation give good results in achalasia, though myotomy is superior in the long term. Indications for surgery are rare in diffuse spasm and nutcracker oesophagus. Non-cardiac chest pain may be related to reflux, diffuse spasm or nutcracker oesophagus, but correlation between motor abnormalities and symptoms is poor and psychological disturbances are frequent.
