Abstract
Khan v Meadows, which was decided recently by the Supreme Court, will have a profound effect on day-to-day clinical practice and future clinical negligence cases. It has clarified the scope of duty of care and to a significant extent links it to the questions being asked by patients of their doctors and by doctors of their colleagues. Will courts now consider that when a patient consults a doctor, he or she is seeking an answer to a specific question or a more general question hidden within that specific question? Clearly the onus will be on clinicians to define exactly what is wanted by the patient or by a colleague.

Abstract
Aims There is evidence of disparate levels of care for members of ethnic minority communities with inflammatory bowel disease in various NHS Trusts and Health Boards in England and Scotland. The purpose of this study was to investigate whether there was any association between the existence of disparate levels of care and the ethnic composition of the management boards of NHS Trusts and Health Boards. It also examined the ethnic composition of Health and Wellbeing Boards associated with these Trusts in England. Method NHS Trusts in England and Health Boards in Scotland, which had been involved in previous studies of disparate levels of care, were identified through a review of the relevant published papers. Health and Wellbeing Boards associated with these Trusts were then identified. Executive and non-executive membership of the NHS Trust, Health Boards and Health and Wellbeing Boards was determined through scrutiny of their web pages. Results The proportion of Asians, who were executive officers, was significantly lower than the proportion who were non-executive board members both for trusts who offered disparate care (z = 2.22; p < 0.03) and those which did not (z = 2.24; p < 0.03). There was no significant difference in the proportion of Asians who were non-executive board members between the two types of trust. The proportion of ethnic minority members of English Health and Well-Being Boards, where there was evidence of disparate levels of care received by South Asian patients was significantly greater than on Boards where this was not the case. (z = 2.8. p < 0.005). Conclusions The relation of these findings to disparate levels of care is unclear. However, it may point to a culture of tokenism, where either the members are not truly representative of underserved communities or they are unable to have any influence on local policy decisions. In either case there is an urgent need to develop better links with minority communities who are underserved so that issues can be effectively identified and remedied.

Abstract
To investigate patients' views and expectations when attending outpatient clinics a questionnaire-based study was performed. The questionnaires asked about appointment systems, continuity of care, staff appearance, chaperons and medical students. Patients wanted fixed appointment times, to see the same doctor on successive visits, for the staff to be formally dressed and to have chaperons during examination. The number of medical students should be restricted especially for women patients. Staff should be sensitive to patients' needs.

Abstract
A team of lay counsellors was trained by the Nottingham Counselling Centre to provide advice to members of the East Midlands branch of the National Association for Colitis and Crohn's Disease. Initial contact was by telephone and the results of the first 25 client/counsellor discussions are presented. Twenty enquiries were made directly by the patient and 5 by a relative of the patient. AU but two of the patients were women. The median age of the patients was 52 years with a median duration of symptoms of 3 years. A failure of communication between the patient and other people underlay most of the problems discussed. Eighteen people welcomed the opportunity simply to talk; in 10 cases there was little rapport with their own doctor and in 8 cases people felt too embarrassed to discuss their problems with friends or relatives. This sense of isolation had been anticipated by counsellors from their own experience and may be a substantial, but as yet unrecognized problem amongst many patients with inflammatory bowel disease.

Abstract
AIM In recent years, microscopic colitis has been increasingly diagnosed. This review was carried out to evaluate demographic factors for microscopic colitis and to perform a systematic assessment of available treatment options. METHOD Relevant publications up to December 2013 were identified following searches of PubMed and Google Scholar using the key words 'microscopic colitis', 'collagenous colitis' and 'lymphocytic colitis'. Two-hundred and forty-eight articles were identified. RESULTS The term microscopic colitis includes lymphocytic colitis and collagenous colitis. Both have common clinical symptoms but are well defined histopathologically. The clinical course is usually benign, but serious complications, including death, may occur. A peak incidence from 60 to 70 years of age with a female preponderance is observed. Although most cases are idiopathic, associations with autoimmune disorders, such as coeliac disease and hypothyroidism, as well as with exposure to nonsteroidal anti-inflammatory drugs and proton-pump inhibitors, have been observed. The incidence and prevalence of microscopic colitis is rising and good-quality epidemiological research is needed. Treatment is currently largely based on anecdotal evidence and on results from limited clinical trials of budesonide. Long-term follow-up of these patients is not well established. CONCLUSION The review synthesizes work on the definition of microscopic colitis and the relationship between collagenous and lymphocytic colitis. It reviews the international epidemiology and work on aetiology. In addition, it critically considers the efficacy of a range of treatments.

Abstract
BACKGROUND The guideline offers best practice advice on the care of adults, children and young people with Crohn's disease. AIM To provide clinically effective and cost-effective evidence-based recommendations to guide clinical practice in a clinical guideline commissioned by the National Institute for Health and Clinical Excellence (NICE). METHODS A systematic review of the evidence including critical appraisal, meta-analysis and cost-effectiveness modelling. RESULTS Thirty-one evidence-based recommendations covering induction and maintenance therapy are available. Five key priorities for implementation are identified together with nine future research recommendations. Three guideline versions are available: short (containing just the recommendations), full (containing the full evidence base) and an Understanding NICE guidance for patients and carers. Algorithms have been produced together with a NICE pathway and implementation tools. CONCLUSION These are the first evidence-based clinical and cost-effectiveness guidelines for Crohn's disease in the United Kingdom.

Abstract
BACKGROUND Non-adherence to 5-aminosalicylic acid (5-ASA) medication can limit the established benefits of this therapy in ulcerative colitis (UC). AIM To determine rates and predictors of non-adherence to 5-ASA therapy in UC patients. METHODS Medication adherence was assessed using self-report data and urinary drug excretion measurements. Participants completed a study-specific questionnaire and two validated questionnaires: Beliefs about Medicine Questionnaire (BMQ)-Specific and Satisfaction with Information about Medicines Scale. RESULTS A total of 169 participants provided self-report adherence data; 151 also provided urine samples. Adherence rates were 111/151 (68%) according to self-report and 90/151 (60%) according to urine analysis, but the two measures were not correlated (chi(2) = 0.12, P = 0.725). Logistic regression identified a significant association between self-reported non-adherence and younger age [odds ratio (OR) for increased age 0.954, 95% confidence interval (CI) 0.932-0.976] and also doubts about personal need for medication (OR for BMQ - Specific Necessity scores 0.578, 95% CI 0.366-0.913). For non-adherence based on urine analysis, only South Asian ethnicity was independently associated with non-adherence (OR 2.940, 95% CI 1.303-6.638). CONCLUSIONS Our observations confirm the difficulty of accurately assessing medication adherence. Nonmodifiable (younger age, South Asian ethnicity) and potentially modifiable (medication beliefs) predictors of non-adherence were identified.

Abstract
BACKGROUND A total of 254 senior consultant gastroenterologists with valid e-mail addresses were identified from the membership list of the British Society of Gastroenterology (BSG) 2007. METHODS They were sent by e-mail a questionnaire which dealt with aspects of clinical practice and addressed cancer prevention in ulcerative colitis (UC). Replies were received from 97 clinicians (38% response rate). RESULTS Ninety-one (94%) advised patients with established UC to take 5-aminosalicylate (5-ASA) compounds for life. Seventy-two of the 91 (79%) clinicians co-prescribed 5-ASA compounds with immune modulators for patients with UC. Only 3 clinicians advised patients to take folic acid as a daily supplement. A median of 20% (interquartile range 10%-50%) of their patients with UC were co-prescribed a 5-ASA compound and azathioprine or 6-mercaptopurine. Of these, a median of 3.5% (interquartile 1%-5%) developed neutropenia. CONCLUSIONS Future research needs to be directed at the long-term maintenance treatment and to address questions about which drugs should be used, in what combinations, and with what frequencies.

Abstract
BACKGROUND Lactose, beta-galactose-1,4-glucose, is hydrolysed by the enzyme lactase. Lactose intolerance occurs when lactase deficiency causes clinical symptoms. AIMS To provide an overview of lactose intolerance, including definition, aetiology and epidemiology, the clinical symptoms and diagnostic testing and management. METHODS A literature review was carried out to meet the aims of this paper. This resulted in the analysis of a database of patients tested for lactose intolerance to provide examples of the consequences of problems of terminology identified. CONCLUSIONS The terminology relating to lactose intolerance is confusing for clinicians and researchers. Clinicians need to ensure that these problematic terms do not cause diagnostic mistakes and inappropriate treatment. Researchers should be aware of inconsistent terminology in studies and resultant problems with the interpretation of results.

Abstract
INTRODUCTION The need for patients to be informed about their disease and its management is now widely recognised, as well as their right to make decisions, which might conflict with the views of their clinicians. There remains a need for the clinician to ensure that patients are provided with accurate evidence-based information. This should be in a form which can be readily understood, retained and acted upon. In order to identify patients' views and to establish evidence of this process there is a need to develop decision trees, which demonstrate their active involvement. AIMS AND METHODS A short text was designed to outline choices available to patients who were to undergo a gastroscopy. Its purpose was to describe the forms of sedation available and provide information which would allow patients to make an informed choice. The design was such that choices were to be made by patients in an active way and recorded on a document signed by the patient. RESULTS 97 successive patients completed the choices on an information sheet allowing them to select the nature of their sedation and oral preparation for the procedure. Of these 13 were of South Asian origin and 44 women. 91% of patients wanted some form of sedation or oral anaesthesia. Most (45%) chose lidocaine spray alone, although 5% wished the procedure to be done under a general anaesthetic. 26% of patients wanted the endoscopist to make choices. CONCLUSIONS In summary, patient choice should include the form of sedation or topical anaesthesia in endoscopic practice. The development of a decision tree is an effective way of providing information and recording a patient's choice.

Abstract
The development of 5-aminosalicylic acid (5-ASA) therapy as a life long treatment for ulcerative colitis is reviewed from its origins in the 1940s to the present day. The drug was designed to treat rheumatoid arthritis, but was found helpful in the management of nine patients with ulcerative colitis. This discovery preceded the emergence of the clinical trial as a tool for assessing a new drug’s efficacy; as a result it lacked scientific rigour and was selective in its presentation of results. Nevertheless it identified the future cornerstone of therapy in ulcerative colitis. In 1962, the first double blind controlled trial of sulphasalazine was conducted on 40 patients. Outcome measures were subjective and included symptoms and an assessment of the rectal mucosa. In 1973, the first two papers on the role of sulphasalazine in maintenance of remission were published. Both used placebo controls and had a stratified design. Outcomes were measured using “an intention to treat” approach. The British study of 64 patients used both subjective and objective criteria to assess outcomes. Patients on placebo had a relapse rate four times patients on active treatment and this founded the basis for a life long approach to therapy with 5-ASA compounds in ulcerative colitis. However, in 1985, a small “on demand” study of 32 patients suggested this approach might be as effective as continuous treatment. Some support for this view came from an Italian study which showed no benefit to continued treatment for those in remission for two years or more. The central problem these studies identify is that of adherence to treatment in the long-term. Few studies have considered patients’ attitudes to continuous therapy and it is an area that needs further investigation.

Abstract
AIM To perform a meta-analysis is of published literature reporting standardized mortality ratios (SMR) for Crohn's patients from 1970 to date. METHODS Medline search identified relevant papers. Exploding references identified additional papers. When two papers reviewed mortality of one patient group at different times, the later publication was used. RESULTS Of 13 papers identified, three studies reported SMR below 1.0, two others had confidence intervals including 1.0. All other studies reported mortality higher than the general population. Meta-analysis using a random effects model shows the pooled estimate for SMR in Crohn's disease is 1.52 (95% CI: 1.32 to 1.74 [P < 0.0001]). Meta-regression shows the SMR for these patients has decreased slightly over the past 30 years, but this decrease is not statistically significant (P = 0.08). CONCLUSION Assessing evidence from original studies and conducting a meta-analysis shows age-adjusted mortality risk from Crohn's disease is over 50% greater than the general population. Whilst mortality has improved since the condition was first recognized, further evaluation of the patients studied in the cohorts included here is necessary to assess more recent changes in clinical practice.

Abstract
BACKGROUND The cancer risk of low-grade dysplasia (LGD) in chronic ulcerative colitis is variable and its management remain contentious. AIM To determine the risk of cancer or any advanced lesion once LGD is diagnosed. METHODS A MEDLINE, EMBASE and Pub Med search was conducted using the key words 'surveillance', 'colorectal cancer', 'low-grade dysplasia' and 'ulcerative colitis'. A random effects model of meta-analysis was used. RESULTS Twenty surveillance studies had 508 flat LGD or LGD with dysplasia-associated lesion or mass. An average of 4.3 colonoscopies was performed/patient post-LGD diagnosis (range: 3-7.6). An average of 18 biopsies taken per colonoscopy (range: 9-24) detected 73 advanced lesions (cancer or high-grade dysplasia) pre-operatively. The cancer incidence was 14 of 1000 (95% CI: 5.0-34) person years duration (pyd) and the incidence of any advanced lesion was 30 of 1000 pyd (95% CI: 12-76). When LGD is detected on surveillance there is a ninefold risk of developing cancer (OR: 9.0, 95% CI: 4.0-20.5) and 12-fold risk of developing any advanced lesion (OR: 11.9, 95% CI: 5.2-27). CONCLUSIONS The risk of developing cancer in patients with LGD is high. These estimates are valuable for decision-making when LGD is encountered on surveillance.

Abstract
AIM To obtain the views of specialist registrars on specialty care in the community. METHOD Specialist registrars from five Deaneries in England completed an online questionnaire about their views on employment prospects, the role of specialty care in the community, and the need for additional training in this area. RESULTS One hundred and twenty seven replies were received over a four week period. Thirty (24%) viewed their future employment prospects as consultants as poor or very worrying. Seventy seven (61%) specialist registrars considered that as consultants they will need to work directly in the community. Thirty nine of these (51%) considered the need to work close to patients directly in the community as either a "bad" or "very bad" development. However, 102 (80%) specialist registrars believed that they should receive training on the delivery of specialty care in the community and 96 (76%) wanted this in the form of a university based degree.

Abstract
AIM To investigate the incidence of death in patients diagnosed with Crohn's disease in Cardiff over 20 years ago. METHODS The Cardiff database of patients with Crohn's disease contains data on all patients diagnosed there since 1934. Patients (394) diagnosed before 1 January 1985 were traced and their mortality status on 31 December 2004 was established. RESULTS The overall standardized mortality ratio (SMR) was 1.29 (95% CI 1.12-1.45) and it has not significantly changed since the 1970s. SMR decreases with age, from 16.95 (95% CI 14.99-18.91) for patients aged 10-19 years (although only one death) to 0.92 (95% CI 0.65-1.19) in those over 75 years. Kaplan-Meier analysis of age at death shows that patients diagnosed aged 10-26 years have median age at death of 58 years, those aged 27-52 years of 66 years, those aged 53-58 years of 74 years, and those over 59 years of 79 years. CONCLUSIONS It shows a significantly raised SMR, not statistically changed since the 1970s and similar to other chronic conditions. Patients diagnosed younger have worse prognosis than those diagnosed later in life and a reduced life expectancy compared with the general population.

Abstract
BACKGROUND There are many studies investigating quality of life in recently diagnosed patients and following surgery for Crohn's disease, but there are none investigating quality of life changes with disease duration. The response shift model suggests quality of life improves with time following diagnosis. AIM To assess how well the model applies to patients with Crohn's disease. METHODS The Cardiff Crohn's disease database contains data on all patients diagnosed there since 1934. Three hundred and ninety four patients diagnosed before 1 January 1985 were traced and the mortality status on 31 December 2004 established. Two hundred and eleven still living were sent quality of life questionnaires. Two hundred and eighty five questionnaires were sent to patients with varying disease duration attending out-patient clinics in Leicester. RESULTS Eighty-nine valid replies were received from Cardiff, 63 from Leicester patients diagnosed over 20 years, 69 from Leicester patients diagnosed <10 years. There was no difference in quality of life between newly diagnosed and established patients. Of greatest concern was possible need for ostomy, uncertain nature of disease, and lack of energy. Stepwise regression showed that increased disease severity, older age and smoking adversely affect quality of life. DISCUSSION Quality of life is equally poor in patients with established disease as in those newly diagnosed, and directly correlates with disease severity. The response shift model may not be applicable in Crohn's disease.

Abstract
Many doctors encounter people of different cultural backgrounds for the first time as patients. In Leicester a significant proportion of the area's population comes from a Gujarati and Hindu background. In an attempt to better inform junior doctors about the views and beliefs of their patients, a group of clinicians and administrators developed an information booklet about the beliefs and practices of people from this community. The impact of this booklet on a group of 54 junior doctors' knowledge was investigated over a period of one month. Such an information booklet was found to significantly increase awareness of the cultural background of patients from a minority community and this knowledge was maintained for at least one month after distribution. The study did not investigate impact on attitudes.

Abstract
The uptake of faecal occult blood testing in a workplace based colorectal cancer screening programme was investigated. Altogether 1828 employees aged 41-65 years at a large British industrial company were invited to receive a free faecal occult blood test (Haemoccult). Faecal occult blood tests were completed on three separate days. Patients with positive results were invited to undergo colonoscopy. The number of employees completing kits was measured and differences in compliance according to age, sex, and occupation were tested with a chi2 test. Compliance was 25.4%, and similar in men (25.0%) and women (32.0%, chi2=3.0, not significant). In men, compliance was highest in those aged 51-60 years (30.5% chi2>1.6, p<0.001). Compliance in women aged 41-50 years, 51-60 years, and 61-65 years was similar (Yates's corrected chi2<2.08, not significant). Managers returned more kits than clerical and blue collar workers (28.6% v 23.5%, chi2=5.6, p<0.02). One percent of tests were positive and one patient had a tubular adenoma. Compliance in employees aged 51-60 years was comparable to that achieved in one-off British general practice programmes, but less than that in the large randomised trial of screening in general practices in Nottinghamshire. Health education of large numbers of people is easier at the workplace than in the community. Future screening must target older employees and those with clerical and blue collar jobs.

Abstract
Gastric cancer is a cause of significant morbidity and mortality. There are several risk factors, with occupation emerging as one of these. There is considerable evidence that occupations in coal and tin mining, metal processing, particularly steel and iron, and rubber manufacturing industries lead to an increased risk of gastric cancer. Other "dusty" occupations-for example, wood processing, or work in high temperature environments have also been implicated but the evidence is not strong. The mechanism of pathogenesis of gastric cancer is unclear and the identification of causative agents can be difficult. Dust is thought to be a contributor to the pathological process, but well known carcinogens such as N-nitroso compounds have been detected in some environments. Further research on responsible agents is necessary and screening for detection of precursor gastric cancer lesions at the workplace merits consideration.

OBJECTIVES Formal efforts to improve patient education are associated with fewer disease complications in a number of conditions. The possible relationship between knowledge about ulcerative colitis and its cancer risk, and the development of colorectal cancer using a previously developed and validated instrument-the Crohn's and colitis knowledge (CCKNOW) score-were investigated. METHODS The 24 item CCKNOW questionnaire was mailed to patients known to have developed colorectal cancer as a complication of ulcerative colitis (cases) and to colitics from the Leicestershire inflammatory bowel disease patient database who had not developed cancer (controls). RESULTS The mean (SD) CCKNOW scores for cases was 8.21 (3.02) and for controls was 8.27 (4.3). These scores did not differ significantly between cases and controls (difference 0.06, 95% confidence interval (CI) -1.7 to 1.5, p=0.9). There were four times as many members of the National Association of Crohn's and Colitis (NACC) in the control group compared with the cancer group and patients who are members of NACC achieve statistically significantly higher scores than non-members (11.6 v 7.8, p=0.05, 95% CI -0.1 to 7.6). However, after adjusting for NACC membership, the CCKNOW score did not appear to be associated with having developed cancer (odds ratio 1.04, 95% CI 0.92 to 1.18, p=0.5). CONCLUSIONS The CCKNOW scores were comparable in cases and controls. Thus, in a retrospective study, no evidence has been demonstrated of an association between patient knowledge and the risk of developing colorectal cancer in patients with ulcerative colitis. However, knowledge may have been increased in cases as a direct result of having had colorectal cancer as a complication of ulcerative colitis.

Abstract
BACKGROUND Mucosal ischaemia may contribute to the pathogenesis of Crohn's disease. Microvascular abnormalities have been found in colonic resection specimens, and mucosal levels of constitutive nitric oxide synthase are reduced. AIM To assess the efficacy of a novel, enteric-release formulation of the nitric oxide donor, glyceryl trinitrate, aimed at increasing the mucosal circulation and relaxing smooth muscle in the affected bowel. METHODS The trial was randomized, double-blind and placebo-controlled. Baseline disease activity was assessed by a structured symptom diary, with blood tests and a quality of life assessment. Patients with a Crohn's disease activity index of > or = 150 and < 450 were randomized to receive 12 weeks of either glyceryl trinitrate (initially 6 mg twice daily, increasing to 9 mg twice daily after 6 weeks) or an identical placebo. Assessments were repeated at 6 and 12 weeks. RESULTS Seventy patients (22 male) entered the study; 34 were given glyceryl trinitrate and 36 placebo. At 12 weeks, there were no differences between the treatment groups in terms of Crohn's disease activity index, pain, stool frequency, inflammatory markers or quality of life scores. CONCLUSIONS Enteric-release glyceryl trinitrate did not benefit patients with mild to moderately active Crohn's disease. Whilst ischaemia may contribute to the pathogenesis of Crohn's disease, our results fail to provide supportive evidence for this hypothesis.

Towards better informed consent in endoscopy: a study of information and consent processes in gastroscopy and flexible sigmoidoscopy. Eur J Gastroenterol Hepatol 2001; 13:1467-76.

Abstract
OBJECTIVE To determine the level of knowledge achieved by patients who have read a simple information sheet on gastroscopy and flexible sigmoidoscopy, and to determine the levels of information required by patients and solicitors specializing in clinical negligence. DESIGN Self-administered questionnaires were sent to 516 patients in Leicester and 79 solicitors specializing in clinical negligence in England and Wales. The main objective outcome measures were the correct scores measured in a simple test of the content of information sheets about gastroscopy and flexible sigmoidoscopy. Other scores were based on the opinions of patients and solicitors on the type of information patients should receive and the levels of risk about which they should be informed. RESULTS Of the clinical negligence specialists, 75%, compared with 44% of patients, felt that consent to procedures should be obtained 2 weeks before the test. In addition, 86% of solicitors felt that patients needed to be told about tests on at least two occasions and favoured booklets and videos. Both 48% of solicitors and 38% of patients felt that patients should be told of very uncommon risks, with 16% of clinical negligence specialists expecting patients to be told of risks of 1 in 1,000,000. The majority of patients (98%) and solicitors (95%) felt that patients should be formally tested as to whether they understand what they are told in the consent process. In an initial study of an information leaflet, South Asian patients had significantly poorer scores than English patients on formal testing of their knowledge of the leaflet's content. The poorest response (61% correct) was to a question including the word 'indigestion', which had been omitted from the information leaflet. Its inclusion led to a significant increase in the number answering the question correctly (96%). The positioning of a word in the list of reasons for doing the test was also important. In the flexible sigmoidoscopy leaflet, the word 'anaemia' was placed in the middle of a list of reasons for doing the test; only 85% answered the question correctly. In the sample of patients who received the modified gastroscopy leaflet, recall at 6 months was significantly impaired with most loss of memory being related to the purpose of the test. CONCLUSIONS Consent needs to be supported by easy-to-read information and the patients' understanding needs to be formally tested. Important concepts must be included in this information as well as any uncommon risks of the procedure. In order to ensure that the information can be understood, the text should be reviewed by an experienced educationalist. If the text is to be used in a multicultural setting, it is important to ensure that patients for whom English is not their first language can easily understand it. The movement away from 'informed consent' towards an 'informed decision' process should facilitate these improvements.

Abstract
Our aim was to address the information requirements for ulcerative colitis patients from Asian ethnic minorities in Leicester city. We sought to determine if the information leaflets provided in English could be successfully employed when translated into the common South Asian languages. A postal survey determined the initial demand for information leaflets, offering the leaflet in English, Hindi, Gujarati or Punjabi. Follow up questionnaires were again by post and subsequently by telephone contact. All patients found the leaflets useful, but felt that doctors should do more to help with language problems. On reading the leaflets, sixty-six percent of patients experienced reduced levels of anxiety or no change, whereas thirty-three percent found increased levels of anxiety. Nearly two-thirds of patients felt there was insufficient or satisfactory information in the leaflets. The final response rate for returning the questionnaire was 53%. The leaflets were generally well received, but there may be a role for increased detail, which may in turn reduce anxiety levels. The low response rates highlight the difficulty of communication with this group, suggesting that we need to make more resources available to these patients.

Abstract
Screening has become central to the effective prevention of several diseases, but implementation suffers from difficulties with targeting and rates of compliance. Such issues are also complicated by the need to consider legal provisions regarding confidentiality of patients and other human rights issues. Screening has been an inexact science in relation to, e.g., faecal occult blood testing for colorectal cancer, false positive and false negative tests for HIV, and there have been inadequate quality controls in breast cancer screening programmes. The public need to be made aware of what the screening programmes really offer, balanced against the expectations they may have. There needs to be a clearer understanding of the nature of the contractual and other legal rights of patients/consumers as against providers. A positive screening test may carry adverse consequences as well as benefits. It could alert an insurance company to a risk and lead to additional weighting or even outright rejection for life insurance policies. Job prospects may also be affected for employees. The method of informing patients in relation to screening and screening failure has already been considered by the courts. Realistic information about both screening and treatment efficiency needs to be offered to patients so that they can have a real understanding of what can and cannot be achieved by current science. The development of understanding of the human genome makes the need for clearer legislation in this are more urgent.

Epidemiology and demographics of achalasia. Gastrointest Endosc Clin N Am 2001; 11:235-48, v. [PMID: 11319059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/04/2023]
Abstract
The incidence and prevalence of achalasia has been reported from a limited number of centers in the US, UK, Israel, Zimbabwe, Singapore, and New Zealand. With two exceptions, the studies have been retrospective. The incidence of the disease is about 0.5/10(5)/year with a prevalence of about 8/10(5) population. However, there appear to be striking international variations and also significant differences within countries. The disease occurs with equal frequency in men and women and is commoner with ageing. The appearance of the disease in the older age groups together with the lack of evidence for an autosomal recessive pattern of inheritance would suggest that environmental factors are important in the cause of the disease.

Abstract
BACKGROUND AND AIMS Controversy surrounds the risk of colorectal cancer (CRC) in ulcerative colitis (UC). Many studies have investigated this risk and reported widely varying rates. METHODS A literature search using Medline with the explosion of references identified 194 studies. Of these, 116 met our inclusion criteria from which the number of patients and cancers detected could be extracted. Overall pooled estimates, with 95% confidence intervals (CI), of cancer prevalence and incidence were obtained using a random effects model on either the log odds or log incidence scale, as appropriate. RESULTS The overall prevalence of CRC in any UC patient, based on 116 studies, was estimated to be 3.7% (95% CI 3.2-4.2%). Of the 116 studies, 41 reported colitis duration. From these the overall incidence rate was 3/1000 person years duration (pyd), (95% CI 2/1000 to 4/1000). The overall incidence rate for any child was 6/1000 pyd (95% CI 3/1000 to 13/1000). Of the 41 studies, 19 reported results stratified into 10 year intervals of disease duration. For the first 10 years the incidence rate was 2/1000 pyd (95% CI 1/1000 to 2/1000), for the second decade the incidence rate was estimated to be 7/1000 pyd (95% CI 4/1000 to 12/1000), and in the third decade the incidence rate was 12/1000 pyd (95% CI 7/1000 to 19/1000). These incidence rates corresponded to cumulative probabilities of 2% by 10 years, 8% by 20 years, and 18% by 30 years. The worldwide cancer incidence rates varied geographically, being 5/1000 pyd in the USA, 4/1000 pyd in the UK, and 2/1000 pyd in Scandinavia and other countries. Over time the cancer risk has increased since 1955 but this finding was not significant (p=0.8). CONCLUSIONS Using new meta-analysis techniques we determined the risk of CRC in UC by decade of disease and defined the risk in pancolitics and children. We found a non-significant increase in risk over time and estimated how risk varies with geography.

Abstract
OBJECTIVES The aim of this study was to look at our practice of using azathioprine and to compare our results with those in published trials both from the point of view of response and also the side-effect profile. DESIGN A retrospective case series analysis was done on patients with inflammatory bowel disease (IBD) who were on azathioprine at Leicester General Hospital. METHODS 111 patients (47 males, 64 females, mean age 35.3 years) were included from gastroenterology outpatients records between November 1997 and August 1998. Clinical and demographic details were collected. Response in Crohn's disease was determined using the Harvey-Bradshaw index. In case of ulcerative colitis the following parameters were used: stool frequency; rectal bleeding, weight gain, and general well-being. Logistic regression was performed to look at the influence of age, sex and diagnosis in relation to the response/relapse rate. RESULTS The average duration of treatment with azathioprine was 28.6 months. The starting dose of 1.53 mg/kg was similar to the maintenance dose (1.51 mg/kg). 58 patients had Crohn's disease and 53 patients were diagnosed with ulcerative colitis. 85 patients were steroid-dependent, 9 steroid-resistant, and 17 patients were started on azathioprine on the basis of extensive disease either seen at the time of endoscopy or radiologically. Improvement in clinical features at 3, 6 and 12 months was 69.5, 77 and 84.1%, respectively. 74% patients showed an improvement in relapse rates during the first year on azathioprine compared to 1 year prior to treatment. 68% patients who had shown improvement at 1 year were no longer taking steroids (p = 0.002). Logistic regression did not show any statistically significant influence of age, sex or diagnosis on response. 4.5% patients had leukopenia requiring dose reductions. Severe leukopenia (leukocyte count <2.5 x 10(9)/l) occurred in 3.6% patients. CONCLUSIONS Response rates in our IBD patients on azathioprine are comparable with those of the published data despite using a relatively smaller dose.

Abstract
BACKGROUND The rise in the incidence of Crohn's disease (CD) suggests the role of an environmental factor in the development of the disease in susceptible individuals. Perinatal exposure to infection has been proposed as such an environmental factor. AIM To investigate the influence of birth date on the development of CD in later life. PATIENTS AND METHOD Four registers of patients with CD, diagnosed from 1972 to 1989, were combined, and data from 1624 patients were examined. The birth dates of CD patients were compared with national birth figures for three decades (1941-50, 1951-60, and 1961-70) to avoid temporal changes in birth trends, and year of birth was compared with epidemic measles years between 1951 and 1967. Risk ratios with 95% confidence intervals (CI) and chi(2) tests were performed. RESULTS There were marginal differences between the birth dates of the CD patients and those predicted from the general population. Further analysis of both season of birth and year halves revealed a very weak association with the first half of the year (relative risk 1.14 (95% CI 1.01-1.30)). There was no association between developing CD and birth during measles epidemics between 1951 and 1967. CONCLUSIONS In utero or perinatal exposure to seasonal environmental factors are unlikely potential aetiological agents in the later development of CD.

Abstract
This project's aim was to assess patients perceived need for a specialist nurse in inflammatory bowel disease. A letter was sent to 64 patients with a summary of the potential role of a specialist nurse. Patients were asked to complete a questionnaire of 10 scenarios on who would be their preferred provider on the range of issues. There were 35 (55%) replies. When comparing the results between the consultant and the specialist nurse patients preferred to see a specialist nurse significantly in four scenarios, and patients preferred to see the consultant significantly in two scenarios. The results indicate that patients feel specialist nurses would have more time to discuss issues and they do not want to bother the busy doctors with them. But they do want doctors to carry out the medical aspects of their care.

Abstract
BACKGROUND/AIMS To investigate risk factors for infection with Helicobacter pylori in a general population sample who accepted an invitation to be screened. In particular, to determine whether being the spouse of an infected subject is an independent risk factor for infection after adjustment for other risks. METHODOLOGY A serological screening test for Helicobacter pylori was offered to 4015 randomly selected subjects registered at a single general practice in Market Harborough, UK. Those invited were also asked to complete a questionnaire if attending for screening; this included information relating to possible risk factors for infection. Results were analyzed in the overall sample of attenders and a subset of married couples, using univariate and multivariate analyses. RESULTS Complete results were obtained for 1431 (36%) subjects. Age, childhood social class and household crowding in childhood were independent risk factors after adjustment for other variables. Positive status of spouse was an independent risk factor in a subset of 389 married couples (P = 0.005, Odds Ratio: 2.65, 95% Confidence Interval: 1.34-5.25). CONCLUSIONS Our study confirmed the correlation between childhood living conditions and infection with Helicobacter pylori. In the study population, having a Helicobacter pylori-positive spouse was associated with a significant increased risk of being infected.

Abstract
BACKGROUND The aim of this study was to assess the colorectal cancer surveillance practices of British gastroenterologists for patients with ulcerative colitis. METHODS A questionnaire that investigated aspects of surveillance in patients with ulcerative colitis was mailed to all consultant gastroenterologists in the U.K. (n = 413). RESULTS Three hundred forty-one questionnaires were returned (response rate 83%). Ninety-four percent of consultants practice cancer surveillance in ulcerative colitis, with 35% maintaining a registry of patients in surveillance programs. All gastroenterologists perform surveillance in patients with pancolitis, 24% in those with left-sided colitis and 2% in patients with proctitis. The mean duration of disease before surveillance is commenced is 9.2 years for pancolitis and 12.4 years for left-sided colitis (p < 0.0001). Only 4% of gastroenterologists routinely offer patients with disease of more than 10 years' duration a prophylactic colectomy. Colonoscopies are conducted by an accredited gastroenterologist in 65% of cases and biopsies are reviewed by specialists in gastrointestinal pathology in 45%. When histology reveals low-grade dysplasia only 4% advise colectomy and when high-grade dysplasia is found 53% recommend colectomy. Sixteen percent of gastroenterologists were unaware of the significance of a dysplasia associated lesion or mass. CONCLUSION The majority of gastroenterologists practice surveillance on a disorganized basis. There is inconsistency in the management of patients with dysplasia and education of gastroenterologists is needed.
