Abstract
OBJECTIVE The recurrence of Crohn's Disease after ileo-colonic resection is a crucial issue. Severe endoscopic lesions increase the risk of developing early symptoms. Prevention and treatment of post-operative Endoscopic Recurrence (ER) have been studied with conflicting results. We compare effi cacy of azathioprine (AZA) vs. high-dose 5-aminosalicylic acid (5-ASA) in preventing clinical recurrence and treating severe post-operative ER. PATIENTS AND METHODS We performed a 1-year multicenter randomized double-blind double-dummy trial. Primary end-points were endoscopic improvement and therapeutic failure (clinical recurrence or drug discontinuation due to lack of efficacy or adverse events) 12 months after randomization. We also performed a post-trial analysis on symptomatic and endoscopic outcomes 10 years after the beginning of the trial, with a median follow-up of 60 months. RESULTS Therapeutic failure occurred in 8 patients (17.4%) within 12 months from randomization, with no significant difference between patients treated with 5-ASA (20.8%, 5 patients) and those with AZA (13.6%, 3 patients). Therapeutic failure was due to clinical recurrence in the 5-ASA group and to adverse events in the AZA group. Endoscopic improvement at 12 months was observed in 8 patients, 2 (11.8%) in the 5-ASA group and 6 (30%) in the AZA group. No serious adverse event was recorded. At the post-trial analysis (median follow-up 60 months), 47.8% (22/46) of patients experienced clinical recurrence: 54.2% (13/24) in the 5-ASA group and 40.9% (9/22) in the AZA group, p=0.546. Patients treated with AZA had lower risk of drug escalation. Clinical recurrence was associated with smoking (p=0.031) and previous surgery (p=0.003). CONCLUSIONS Our trial indicates that there was no difference in terms of treatment failure between 5-ASA and AZA in patients with severe ER. The main limit of AZA is its less favorable safety profile.

Abstract
AIM Several population-based studies have shown that long term prognosis of ulcerative colitis (UC) may be better than previously reported. The aim of this study was to evaluate the course of UC in a referral center cohort in the pre-biologic era and to identify possible prognostic factors. METHODS All patients with established diagnosis of UC have been extracted from our GI Unit IBD Database. Clinical and demographic characteristics of all patients were recorded at the time of diagnosis. The disease course was retrospectively evaluated considering four primary end points: change in disease extension, need of corticosteroids, need of immunomodulators, and need of colectomy. The Kaplan-Meier survival method was used to estimate the cumulative probability of a course free of the outcome of interest. RESULTS Eight hundred and seven UC patients diagnosed between 1984 and 2008 have been included: 21.8% had proctitis, 47.6% had distal colitis and 30.6% had extensive colitis. The median follow up after diagnosis was 91 months (range 12-596). The probability of extension of proctitis within 10 years was 39.7%. In the whole cohort, the 10 years probability of receiving corticosteroids and immunomodulators was 46.7% and 12.4%, respectively. The 10-year probability of colectomy was 6.5%. Extensive colitis was associated with a higher probability of receiving corticosteroids, immunomodulators and surgery. CONCLUSION Long-term prognosis of UC is favourable for the majority of patients. Extensive colitis is the most relevant negative prognostic factor. Results from our referral center study are similar to that reported in population-based studies. Further studies are required to assess the possible impact of biologics and new treatment strategies on long term outcomes.

Abstract
Diverticular disease of the colon is the fifth most important gastrointestinal disease in terms of direct and indirect healthcare costs in western countries. Although most patients with colonic diverticula remain asymptomatic for their whole life, in 20-25% of cases will develop symptoms. Antibiotics are commonly used in the treatment of inflammatory complication of diverticular disease. Several clinical observation suggest a role of rifaximin in the management of symptomatic uncomplicated diverticular disease of the colon. This is a critical review of clinical studies addressing the role of long term administration of rifaximin for the treatment of symptomatic colonic diverticular disease. The evidence from prospective controlled trials suggests that rifaximin is effective for obtaining symptomatic relief in patients with uncomplicated diverticular disease. The therapeutic gain compared with fiber supplementation only is approximately 30%. No definitive conclusion can be drawn regard a possible role of rifaximin for preventing diverticulitis.

Abstract
AIM Surgery is an almost inevitable event in Crohn's disease (CD) but is not curative; postoperative recurrence follows a predictable course. Several factors potentially affecting the risk of recurrence have been investigated but results are largely inconclusive. The aim of the present study was to evaluate the long-term course of ileo-caecal CD after surgery and to identify possible predictors of clinical and surgical recurrence. METHODS Patients with ileo-caecal CD who had undergone surgical resection and with at least one year of post-operative follow-up were studied. The postoperative course was retrospectively evaluated. The primary end-points were clinical recurrence (defined as reappearance of symptoms requiring steroid treatment in the presence of endoscopic and/or radiologic recurrence) and surgical recurrence, defined as need for reoperation. RESULTS Two hundred and twelve patients were included in the study. Median follow-up after surgery was 117 months (interquartile range 51-216). The cumulative probability of a post-operative course without clinical and surgical recurrence after 30, 60, 90, 120 months was 78.2%, 69.4%, 58.0%, 50.6% and 97.0%, 96.4%, 85.6%, 72% respectively. Early surgery (within three years from diagnosis) was associated with a longer postoperative course without clinical recurrence compared with late surgery (performed after three years from diagnosis). None of the other clinical variables considered (gender, age, family history for IBD, smoking habits, pattern of CD, and postoperative prophylactic treatment) was associated with the risk of clinical and surgical recurrence. CONCLUSION Surgery is an excellent treatment for patients with isolated ileo-caecal CD. The overall long-term outcome is good: by 10 years after operation approximately 50% of patients are free of clinical recurrence and over 70% do not require further surgery. Surgery, therefore, continues to play an important role in ileo-caecal CD and should therefore not be considered only a failure of medical treatment.

Abstract
BACKGROUND Perianal fistulas are frequent complications of Crohn's disease. Intravenous infliximab can control perianal disease and promote perianal fistula closure. Perifistular infliximab injections have been proposed for patients who are intolerant or unresponsive to intravenous therapy. The aim of this study was to assess the long-term efficacy of surgical treatment combined with local infliximab therapy. METHODS A prospective cohort study was designed. Twelve patients with Crohn's disease and high/complex transphincteric and intrasphincteric perianal fistulas refractory to other treatment were submitted to core-out fistulectomies, plus perifistular injections of infliximab (20-25 mg in 15-20 ml of 5% glucose) every 4-6 weeks. The main outcome measure was the clinical closure of all perianal fistulas. A 95% confidence interval was calculated for short- and long-term fistula closure rates. RESULTS None of the procedures were associated with local or systemic adverse effects. Four patients did not complete treatment, two because of relapse of intestinal symptoms, which required intravenous infliximab. In one case, treatment with intravenous infliximab was complicated by a hypersensitivity reaction. Eight patients continued treatment until all perianal fistulas were closed and setons were removed (median: 5 sessions). Persistent closure was observed in seven (87.5%, 95% CI: 47.4-99.6) of the eight patients 12 months after completion of treatment and in five (62.5%; 95% CI: 24.5-91.5) of eight at the end of follow-up (range: 19-43 months, median: 35 months). CONCLUSIONS The cohort we examined is small, but fistulectomy combined with repeated perifistular injections of infliximab appears to be safe and may help in fistula healing. However, in most patients, permanent closure of all fistulas is not achieved.

Abstract
BACKGROUND Diverticular disease of the colon is a common gastrointestinal disease. Although most patients remain asymptomatic for their whole life, about 20-25% present symptoms related to 'diverticular disease'. Several randomised trials verified efficacy of a poorly absorbed antibiotic, such as rifaximin-α (rifaximin), in soothing symptoms and preventing diverticulitis. AIM To evaluate the long-term efficacy administration of rifaximin plus fibre supplementation vs. fibre supplementation alone, on symptoms and complications, in patient with symptomatic uncomplicated diverticular disease. METHODS Pertinent studies were selected from the Medline, and the Cochrane Library Databases, references from published articles and reviews. Conventional meta-analysis according to DerSimonian and Laird method was used for the pooling of the results. The outcomes were 1- year complete symptom relief, and 1- year complication incidence. The rate difference (RD, with 95% CI) and the Number Needed to Treat (NNT) were used as measure of the therapeutic effect on each outcome. RESULTS Four prospective randomised trials including 1660 patients were selected. The pooled RD for symptom relief was 29.0% (rifaximin vs. control; 95% CI 24.5-33.6%; P<0.0001; NNT=3). The pooled RD for complication rate was -1.7% in favour of rifaximin (95% CI -3.2 to -0.1%; P=0.03; NNT=59). When considering only acute diverticulitis, the pooled RD in the treatment group was -2% (95% CI -3.4 to -0.6%; P=0.0057; NNT=50). CONCLUSIONS In symptomatic uncomplicated diverticular disease, treatment with rifaximin plus fibre supplementation is effective in obtaining symptom relief and preventing complications at 1 year.

Abstract
BACKGROUND Prevention of post-operative recurrence has a central role in the management of Crohn's Disease (CD). Many drugs have been evaluated in prospective randomised controlled trials (RCTs) but the results are disappointing. Mesalazine, the drug more extensively investigated, has been shown to be effective for preventing recurrence in the short-term; however, the overall benefit is small and no data are available on the long-term effectiveness. AIM To compare the long-term occurrence of post-operative recurrence in patients who received regular prophylactic treatment with mesalazine with patients who did not receive prophylaxis after the first radical resection for ileo-caecal CD. PATIENTS AND METHODS The records of 216 patients with ileo-caecal CD at their first resection were reviewed: 146 patients (67.6%) received post-operative prophylaxis with mesalazine while 70 patients (32.4%) received no prophylaxis. Allocation of patients in the two groups was determined by patients' preferences and by different policies in the post-operative prophylactic approach. The mean follow-up after surgery was 153.7 months (range 12-544). The co-primary endpoints were post-operative clinical and surgical recurrence. STATISTICAL ANALYSIS Kaplan-Meier survival method, Chi-square, Student t-test. RESULTS The two groups were comparable with regard to gender, age at surgery, smoking habits, pattern of CD (perforating/not perforating), and disease duration before surgery. One year after surgery, a small, not statistically significant, risk reduction in clinical recurrence was observed in mesalazine treated group (-7.6%; 95% CI -18.0% to 2.8%). Within 10 years after surgery, the cumulative probability of clinical recurrence and surgical recurrence were similar in the two groups (Log Rank test p=0.9 and p=0.1 respectively). CONCLUSION Mesalazine prophylaxis is not effective for preventing the long-term post-operative recurrence in ileo-caecal Crohn's disease.

Abstract
BACKGROUND Severe ulcerative colitis is a potentially life-threatening condition. Due to advances in medical therapy, the mortality rate has dropped to <2% over the past 30 years, but the colectomy rate reaches 30%. Recently, infliximab has been shown to be effective as rescue therapy but little is known about long-term benefits. AIM To evaluate short-and long-term colectomy rates for severe ulcerative colitis in the era of biological treatment and to identify predictive factors of long-term colectomy. PATIENTS AND METHODS From 2001 to 2006 all in-patients with severe ulcerative colitis, according to Truelove and Witts criteria, were retrospectively reviewed. All patients had received intravenous steroid treatment; infliximab (5 mg/kg at 0, 2 and 6 weeks) was used as rescue therapy in steroid-refractory patients; colectomy was performed in patients who deteriorated whilst on steroid treatment or failed to respond to infliximab. RESULTS Of the 314 ulcerative colitis patients hospitalized during the study period, 52 (16.5%) met the criteria of severe ulcerative colitis. After median 7 days (range 4-15) on intravenous steroids, 37/52 (71%) patients showed a clinical response, while 15/52 (29%) were steroid-refractory. Of these, four underwent urgent colectomy and 11 received infliximab. A clinical response was observed in all infliximab-treated patients. In the long-term, another six patients underwent elective colectomy. The overall colectomy rate, following the acute attack, was 19%; the cumulative probability of a course without colectomy was 90%, 86%, 84%, 81%, after 6, 12, 18 and 24 months, respectively. No deaths occurred. The long-term colectomy risk was comparable in patients treated with infliximab and in steroid-responsive patients (18% vs. 11% respectively; OR 1.9; 95% CI 0.26-14.5). No predictive factors of colectomy, in the long-term, were identified. CONCLUSIONS Surgery continues to play an important role in acute severe ulcerative colitis. Infliximab can avoid urgent colectomy in steroid-refractory patients but the risk of elective colectomy, in the long-term, is not modified.

Abstract
BACKGROUND Surgical resection is almost inevitable in Crohn's disease. Surgery is usually performed for refractory or complicated disease: no studies appear to have been carried out, so far, to evaluate the potential benefits of performing surgery early in the course of the disease. AIM To compare the long-term course of Crohn's disease following ileo-caecal resection performed at the time of diagnosis (early surgery) or during the course of the disease (late surgery). Patients and methods Overall 207 patients with ileo-caecal Crohn's disease at their first resection were reviewed: 83 patients underwent surgery at the time of diagnosis (early surgery), while 124 underwent surgery 54.2 months (range 1-438) after diagnosis (late surgery). The mean follow-up after surgery was 147 months (range 12-534). The primary endpoint was clinical recurrence, defined as need for corticosteroids for symptomatic disease in the presence of endoscopic and/or radiologic recurrence. Secondary endpoints were need for immunosuppressants and surgical recurrence. STATISTICAL ANALYSIS Kaplan-Meier survival method and Cox proportional hazards regression model. RESULTS Within 10 years after surgery, the cumulative probability of clinical recurrence was significantly lower in the early surgery group (Log Rank test P = 0.01). A trend was observed regarding the need for immunosuppressants (P = 0.05). No difference was observed regarding surgical recurrence. At multivariate analysis, early surgery was the only independent variable associated with a reduced risk of clinical recurrence (Hazard ratio, HR = 0.57; 95% CI 0.35 to 0.92, P = 0.02), but not with need for immunosuppressants and surgical recurrence (HR = 0.51; 95% CI 0.20 to 1.30, P = 0.15; HR = 0.66; 95% CI 0.33 to 1.35, P = 0.25, respectively). CONCLUSION Early surgery prolongs clinical remission compared to surgery performed during the course of the disease, but the natural history of disease is not modified.

Abstract
BACKGROUND Topical beclomethasone diproprionate has shown efficacy in ulcerative colitis. AIM To assess, in a multicenter, randomized, double-blind study, the tolerability and safety of topical beclomethasone diproprionate (3mg) enema and foam versus mesalazine (2g) enema and foam in mild-moderate distal ulcerative colitis. PATIENTS In 15 referral gastrointestinal units, 99 patients with distal ulcerative colitis were enrolled. This number was lower than planned according to the statistical analysis, due to a low recruitment rate. METHODS Patients were randomly assigned to random preparations (beclomethasone diproprionate enema, beclomethasone diproprionate foam, mesalazine enema, mesalazine foam) once nightly for 8 weeks, with clinical and endoscopical assessment (Disease Activity Index score) at baseline (T0), 4 (T4) and 8 weeks (T8). Results were expressed as median and range (95% confidence interval). The efficacy was assessed by comparing the Disease Activity Index value at T4 and T8 by using the Student's t-test or the Wilcoxon-Mann-Whitney test. RESULTS Efficacy was comparable in the beclomethasone diproprionate or mesalazine groups at both T4 and T8 (response at T4: beclomethasone diproprionate 78% [95% confidence interval 0.6-0.8] versus mesalazine 79% [95% confidence interval 0.6-0.8]; T8: beclomethasone diproprionate 84% [95% confidence interval 0.7-0.9] versus mesalazine 90% [95% confidence interval 0.7-1.0]; p=n.s.; remission at T4: beclomethasone diproprionate 24% [95% confidence interval 0.1-0.3] versus mesalazine 28% [95% confidence interval 0.1-0.3]; remission at T8: beclomethasone diproprionate 36% [95% confidence interval 0.2-0.5] versus mesalazine 52% [95% confidence interval 0.3-0.6]; p=n.s.). The Disease Activity Index lowered at T4 and T8 versus T0 in the four groups (T4 versus T0: beclomethasone diproprionate foam Disease Activity Index 2 versus 6 p<0.0001; beclomethasone diproprionate enema 4 versus 6, mesalazine enema 3 versus 6, mesalazine foam 3.5 versus 7, p<0.001 for all three groups; T8 versus T0: p<0.01). The Disease Activity Index lowered at T8 versus T4 in the beclomethasone diproprionate enema and foam (Disease Activity Index: 2 versus 4 and 1 versus 4, respectively; p<0.05) and in the mesalazine enema (Disease Activity Index: 1.5, range 0-4 versus 3, range 0-12; p<0.01), but not in the mesalazine foam group (Disease Activity Index: 1, range 0-9 versus 3.5, range 0-8; p=n.s.). The safety profile was favourable for all groups. CONCLUSIONS Beclomethasone diproprionate and mesalazine enema and foam show a comparable tolerability and efficacy in mild active distal ulcerative colitis.

Abstract
BACKGROUND Mucosa-infiltrated granulocyte neutrophils are an early characteristic of inflammation and the main histological feature of active ulcerative colitis. Mucosal healing has recently been indicated as an important tool in the evaluation of response to treatment. While several studies have stressed the efficacy of granulocyte-monocyte-apheresis in inducing clinical remission in active ulcerative colitis, few data are available on mucosal features. AIM Aim of this study was to assess the effects of granulocyte-monocyte-apheresis on clinical and mucosal features in patients with ulcerative colitis, dependent upon or refractory to steroids. MATERIAL AND METHODS From April 2004 to April 2005, 12 patients (5 females, 7 males, mean age 49 years, range 33-71 years), with mild-moderate ulcerative colitis (six left colitis, six pancolitis) dependent/refractory upon steroids were enrolled. Each patient was treated for a 5-week period with five cycles of granulocyte-monocyte-apheresis. Patients were evaluated at baseline and 1 week after the last apheresis by means of Global Physician Assessment, quality of life features, laboratory tests (erythrocyte sedimentation rate, CRP, full blood count, faecal calprotectine), endoscopy and histology. RESULTS At week 6 of follow-up, complete mucosal healing was observed in 3 out of 12 patients, partial mucosal healing in 8 patients and no change in 1 patient. Clinical response was complete in 8 out of 12 patients. CONCLUSIONS These data suggest that granulocyte-monocyte-apheresis induces an improvement both in clinical and mucosal lesions in steroid-dependent/refractory ulcerative colitis. Of note, the reduction in granulocyte infiltration and the improvement in mucosal lesions are accompanied by a reduction in faecal calprotectine.

Abstract
BACKGROUND Seasonal variations in onset of symptoms have been reported in ulcerative colitis but not in Crohn's disease. AIM.: To investigate whether our inflammatory bowel diseases patients presented seasonal variations in onset of symptoms. PATIENTS AND METHODS Patients with a diagnosis of inflammatory bowel diseases established between 1995 and May 2004, and consecutively observed from June 2003 to May 2004, were included in the study. Onset of symptoms (year, season and month) was recorded. Expected onsets with a uniform distribution during the year were calculated and compared to observed onsets. STATISTICAL ANALYSIS chi-square test, odds ratio (95% confidence interval). RESULTS Overall 425 inflammatory bowel diseases patients were enrolled. Onset of symptoms (year and season) was established in 353/425 patients (83%; 150 Crohn's disease; 203 ulcerative colitis). Onset of symptoms in inflammatory bowel diseases patients as a whole occurred more frequently in spring-summer compared to autumn-winter (odds ratio 1.39; 95% confidence interval 1.03-1.87; p<0.03). This variation was observed in Crohn's disease (odds ratio 1.59; 95% confidence interval 1.00-2.51; p<0.05) and a similar trend, although not significant, was observed in ulcerative colitis (odds ratio 1.27; 95% confidence interval 0.86-1.88; p=0.27). CONCLUSIONS These data indicate that onset of Crohn's disease symptoms occurred more frequently during spring-summer. A similar trend was observed in ulcerative colitis. Environmental factors, such as associated infections, smoking, use of drugs and seasonal changes in immune function may be responsible for triggering the clinical onset of inflammatory bowel diseases.

Abstract
BACKGROUND AND AIMS The widespread use of anti-tumour necrosis factor alpha antibody (Infliximab) in Crohn's disease (CD) raises concerns about a possible cancer risk in the long term. In a matched pair study, we assessed whether Infliximab is associated with an increased risk of neoplasia. METHODS In a multicentre matched pair study, 404 CD patients treated with Infliximab (CD-IFX) were matched with 404 CD patients who had never received Infliximab (CD-C). Cases and controls were matched for sex, age (+/-5 years), site of CD, age at diagnosis (+/-5 years), immunosuppressant use, and follow up. New diagnoses of neoplasia from April 1999 to October 2004 were recorded. RESULTS Among the 404 CD-IFX, neoplasia was diagnosed in nine patients (2.22%) while among the 404 CD-C, seven patients developed neoplasia (1.73%) (odds ratio 1.33 (95% confidence interval 0.46-3.84); p=0.40). The survival curve adjusted for patient year of follow up showed no differences between CD-IFX and CD-C (p=0.90; log rank test). In the CD-IFX group, there was one cholangiocarcinoma, three breast cancers, one skin cancer, one leukaemia, one laryngeal cancer, and two anal carcinomas. Among the 7/404 (1.73%) CD-C, there were three intestinal adenocarcinomas (two caecum, one rectum), one basalioma, one spinalioma, one non-Hodgkin's lymphoma, and one breast cancer. Age at diagnosis of neoplasia did not differ between groups (CD-IFX v CD-C: median 50 (range 40-70 years) v 45 (27-72); p=0.50). CONCLUSION In our multicentre matched pair study, the frequency of a new diagnosis of neoplasia in CD patients treated with Infliximab was comparable with CD patients who had never received Infliximab.

Abstract
BACKGROUND Almost 20% of patients with active Crohn's disease are refractory to conventional therapy. Infliximab is a treatment of proven efficacy in this group of patients and it is not clear which variables predict a good response. AIMS.: To evaluate the role of infliximab looking at the predictors of response in a large series of patients with Crohn's disease. PATIENTS AND METHODS Five hundred and seventy-three patients with luminal refractory Crohn's disease (Crohn's Disease Activity Index (CDAI)>220-400) (312 patients) or with fistulising disease (190 patients) or both of them (71 patients) were treated with a dose of 5 mg/kg in 12 Italian referral centres. The primary endpoints of the study were clinical response and clinical remission for luminal refractory and fistulising disease. We evaluated at univariable and multivariable analysis the following variables: number of infusions, sex, age at diagnosis, smoking habit, site of disease, previous surgery, extraintestinal manifestations and concomitant therapies, and type of fistulas. RESULTS Patients with luminal refractory disease: 322 patients (84.1%) had a clinical response and 228 (59.5%) reached clinical remission. Patients with fistulising disease: 187 patients (72%) had a reduction of 50% of the number of fistulas and in 107 (41%) a total closure of fistulas was observed. For luminal disease, single infusion (OR 0.49, 95% CI 0.28-0.86) and previous surgery (OR 0.53, 95% CI 0.30-0.93) predicted a worse response for fistulising disease. Other fistulas responded worse than perianal fistulas (OR 0.57, 95% CI 0.303-1.097). CONCLUSION In Crohn's disease infliximab is effective in luminal refractory and in fistulising disease. A single infusion and previous surgery predicted a worse response in luminal disease whereas perianal fistulas predicted a better response than other type of fistulas.

Abstract
INTRODUCTION Despite the explosion of biological therapies, the old immunosuppressants continue to play a pivotal role in the management of inflammatory bowel diseases. AIM To assess the appropriateness of immunosuppressants-azathioprine, 6-mercaptopurine, methotrexate, cyclosporine A, tacrolimus (FK506), mycophenolate mofetil and thalidomide-in the treatment of inflammatory bowel disease by using RAND/University of California Appropriateness Method. METHODS The RAND method consists of a combination of evidence from the literature and experts' opinions. Appropriateness has been defined to mean that the expected health benefit exceeds the expected negative consequences by a sufficiently wide margin. A panel of 10 experts from the Italian Group for Inflammatory Bowel Disease has rated, in two rounds, on a scale from 1 to 9, the appropriateness of each indication selected by the Promoter Centre, on the basis of their own clinical experience. An indication was considered appropriate if the median of the panelists' ratings fell within the area 7-9, inappropriate in the area 1-3 and uncertain in the area 4-6. A total of 2781 indications were grouped into 13 categories (mild to moderate Crohn's disease; severe Crohn's disease; fistulizing Crohn's disease; steroid-dependant and -resistant Crohn's disease; maintenance of remission induced by medical treatment in Crohn's disease; maintenance of remission induced by surgery in Crohn's disease; mild to moderate ulcerative colitis; severe ulcerative colitis; steroid-dependant and -resistant ulcerative colitis; maintenance of remission induced by medical treatment in ulcerative colitis; extra-intestinal manifestations in inflammatory bowel disease; pregnancy and inflammatory bowel disease; azathioprine-resistant or -intolerant inflammatory bowel disease patients). RESULTS Of the 2781 scenarios, 212 (7.6%) were rated appropriate, 645 (23.2%) uncertain and 1924 (69.2%) inappropriate. The most relevant results were: in steroid-dependant or -resistant Crohn's disease, azathioprine, 6-mercaptopurine and methotrexate were defined as appropriate in 25 (86.2%) and 14 (48.3%) of the 29 scenarios respectively; in Crohn's disease, azathioprine and 6-mercaptopurine were defined as appropriate combined with Infliximab (bridge therapy); in steroid-dependant or -resistant ulcerative colitis, azathioprine and 6-mercaptopurine were defined as appropriate in 45 (77.6%) out of 58 scenarios, while methotrexate was defined appropriate only after previous azathioprine failure; in severe ulcerative colitis, cyclosporine A was defined as appropriate only after previous failure with steroids; in azathioprine-intolerant or -resistant inflammatory bowel disease patients, methotrexate was appropriate in 20 (66.7%) out of 30 scenarios; it is inappropriate to stop azathioprine treatment before conception in the presence of active disease. The use of FK506, mycophenolate mofetil and Thalidomide resulted as inappropriate or uncertain. CONCLUSIONS Results of this study show that only azathioprine, 6-mercaptopurine and methotrexate are appropriate in the treatment of inflammatory bowel diseases. Cyclosporine A was found to be appropriate only in severe ulcerative colitis after the failure of steroids. FK506, mycophenolate mofetil and Thalidomide resulted as inappropriate but experience with these agents is somewhat limited.

Abstract
BACKGROUND AND AIMS Crohn's disease is a heterogeneous entity. The Vienna Classification defines three different clinical patterns: 'non-stricturing, non-penetrating', 'stricturing' and 'penetrating'. Aim of this study was to assess the change in clinical behaviour over time and to evaluate whether an evolution towards penetrating complications can be predicted. METHODS A total of 139 patients with non-penetrating behaviour at the time of diagnosis were included. The mean follow-up was 4.84 years (range 1-23.2 years). The clinical behaviour, according to the Vienna Criteria, was assessed at the diagnosis and at the end of follow up. Statistical analysis was performed by means of the Kaplan-Meier method and standard logistic regression analysis. RESULTS The cumulative probability of a change in clinical behaviour was 22, 38 and 63% at 3, 6 and 12 years, respectively, and the cumulative probability of developing penetrating complications was 22, 33 and 55% at 3, 6 and 12 years, respectively. Young age at diagnosis (<40 years) and a stricturing behaviour are independent risk factors of developing major penetrating complications (internal fistula, mass or abscess): OR=6.0, 95% CI 1.1-30.5; OR=4.0, 95% CI 1.5-10.9, respectively, but not perianal disease. CONCLUSIONS The behavioural classification of Crohn's disease is a dynamic model in which each status should be considered as not fixed but evolutive. Perianal disease should be considered a distinct pattern of penetrating behaviour.

Abstract
UNLABELLED This study provides the long-term follow-up data on the efficacy of infliximab in the treatment of chronic refractory pouchitis complicated by fistulae following ileo-pouch anal anastomosis (IPAA) for ulcerative colitis (UC). METHODS Seven patients (4 F, 3 M) with chronic refractory pouchitis complicated by fistulae were included in an open study. Pouchitis was diagnosed by clinical plus endoscopical and histological criteria. Fistulae were: pouch-bladder in 1, vaginal in 3, perianal in 2, both vaginal and perianal in 1 patient. Extraintestinal manifestations were present in 4 patients. All the patients were refractory to antibiotics (3 patients also to steroids). Crohn's disease was carefully excluded in all patients after re-evaluation of the history, re-examination of the original proctocolectomy specimen, examination of the proximal small bowel. Patients received Infliximab 5 mg/kg at 0, 2 and 6 weeks. Azathioprine (2.5 mg/kg) was also started for all patients as bridge therapy. Clinical response was classified as complete, partial, and no response. Fistulae closure was classified as complete, partial, and no closure. The pouchitis disease activity index (PDAI) and quality of life (QoL) were also used as outcome measures. RESULTS Clinically, all patients improved. At 10-week follow-up, 6 out of 7 patients had a complete clinical response, and 5 out of 7 patients had complete fistulae closure. At 10- week follow-up, median PDAI dropped from 12 (baseline) (range, 10-15) to 5 (range, 3-8); median QoL decreased from 37 (range, 33-40) to 14 points (range, 9-18), respectively. Extraintestinal manifestations (erythema nodosum and arthralgiae) completely remitted soon after the first infusion of infliximab. Clinical response and fistulae closure were maintained in the long-term follow-up. CONCLUSIONS These results seem indicate that infliximab plus azathioprine may be recommended for the treatment of refractory pouchitis complicated by fistulae following IPAA for UC.

Abstract
BACKGROUND Three variants of the NOD2/CARD15 gene are strongly associated with susceptibility to Crohn's disease; however, striking racial and geographic differences of their frequency have been described. AIMS We have compared the allele frequencies of familial cases of Crohn's disease recruited in a multicentre study across Italy, in order to disclose possible geographic heterogeneity. Moreover, we also compared the allele frequencies in sporadic cases of Crohn's disease and healthy controls from Southern Italy with those reported in other two populations from Central and Northern Italy. SUBJECTS AND METHODS A total of 731 subjects were genotyped for the polymorphism of three main variants (R702W, G908R and 1007 fs): 152 patients were familial cases of Crohn's disease, 183 were healthy first-degree relatives, 180 were sporadic cases of Crohn's disease, and 216 were unrelated healthy subjects. RESULTS The frequency of the frameshift mutation (1007 fs) was significantly higher in both familial and sporadic cases of Crohn's disease (P = 0.000001), and healthy first-degree relatives (P = 0.0001) compared to controls. At least one risk allele was found in 44% of familial Crohn's disease patients, compared to 7% of healthy controls (OR = 4; CI = 2-6.5). Two risk alleles were found in 14% of familial Crohn's disease, compared to less than 1% of controls (OR = 26: CI = 4-129). CONCLUSIONS Our data confirm the strong correlation between the 1007 fs variant and Crohn's disease, in both familial and sporadic cases. Moreover, no significant difference of allele frequencies was detected in familial cases, sporadic cases and healthy controls among different geographic areas of Italy.

Abstract
AIM To determine the efficacy of infliximab in the treatment of chronic refractory pouchitis complicated by fistulae following ileal pouch-anal anastomosis for ulcerative colitis. METHODS This open study included seven patients (four females, three males) with chronic refractory pouchitis complicated by fistulae. Pouchitis was diagnosed by clinical, endoscopic and histological criteria. The sites of the fistulae were as follows: pouch-bladder in one, vaginal in three, perianal in two, and both vaginal and perianal in one. Extra-intestinal manifestations (erythema nodosum, arthralgia) were present in four patients. Crohn's disease was carefully excluded in all patients after re-evaluation of the history, re-examination of the original proctocolectomy specimen and examination of the proximal small bowel. All patients had been treated with antibiotics and three with steroids. Patients received infliximab, 5 mg/kg, at 0, 2 and 6 weeks. Azathioprine (2.5 mg/kg) was also started for all patients as bridge therapy. Clinical response was classified as complete, partial or no response. Fistulae closure was classified as complete (cessation of fistulae drainage and total closure of all fistulae), partial (a reduction in the number, size, drainage or discomfort associated with fistulae) or no closure. The pouchitis disease activity index and quality of life were also used as outcome measures. RESULTS Clinically, all patients improved. At the 10-week follow-up, six of the seven patients had a complete clinical response, and five had complete fistulae closure. At the 10-week follow-up, the median pouchitis disease activity index decreased from 12 (baseline) (range, 10-15) to 5 (range, 3-8); the median quality of life decreased from 37 points (range, 33-40) to 14 (range, 9-18). Erythema nodosum and arthralgia showed complete remission soon after the first infusion of infliximab. CONCLUSIONS These preliminary results indicate that infliximab may be recommended for the treatment of refractory pouchitis complicated by fistulae following ileal pouch-anal anastomosis for ulcerative colitis.

Abstract
AIM To determine the efficacy of infliximab in the treatment of chronic refractory pouchitis complicated by fistulae following ileal pouch-anal anastomosis for ulcerative colitis. METHODS This open study included seven patients (four females, three males) with chronic refractory pouchitis complicated by fistulae. Pouchitis was diagnosed by clinical, endoscopic and histological criteria. The sites of the fistulae were as follows: pouch-bladder in one, vaginal in three, perianal in two, and both vaginal and perianal in one. Extra-intestinal manifestations (erythema nodosum, arthralgia) were present in four patients. Crohn's disease was carefully excluded in all patients after re-evaluation of the history, re-examination of the original proctocolectomy specimen and examination of the proximal small bowel. All patients had been treated with antibiotics and three with steroids. Patients received infliximab, 5 mg/kg, at 0, 2 and 6 weeks. Azathioprine (2.5 mg/kg) was also started for all patients as bridge therapy. Clinical response was classified as complete, partial or no response. Fistulae closure was classified as complete (cessation of fistulae drainage and total closure of all fistulae), partial (a reduction in the number, size, drainage or discomfort associated with fistulae) or no closure. The pouchitis disease activity index and quality of life were also used as outcome measures. RESULTS Clinically, all patients improved. At the 10-week follow-up, six of the seven patients had a complete clinical response, and five had complete fistulae closure. At the 10-week follow-up, the median pouchitis disease activity index decreased from 12 (baseline) (range, 10-15) to 5 (range, 3-8); the median quality of life decreased from 37 points (range, 33-40) to 14 (range, 9-18). Erythema nodosum and arthralgia showed complete remission soon after the first infusion of infliximab. CONCLUSIONS These preliminary results indicate that infliximab may be recommended for the treatment of refractory pouchitis complicated by fistulae following ileal pouch-anal anastomosis for ulcerative colitis.

Abstract
BACKGROUND The role of mesalazine in preventing the clinical recurrence of Crohn's disease after surgery has been shown in a meta-analysis of all published studies. No clear relationship, however, has been shown between dosage and response. AIM To evaluate whether 4.0 g/day of mesalazine may offer therapeutic advantages over 2.4 g/day in the prevention of both endoscopic and clinical post-operative recurrence of Crohn's disease. METHODS The study was a double-blind, randomized, multi-centre, prospective, controlled clinical trial. Two hundred and six patients, submitted to first or second intestinal resection for Crohn's disease limited to the terminal ileum, with or without involvement of the caecum/ascending colon, were enrolled. Of these, 101 were randomly allocated to receive 4.0 g/day of mesalazine (Asacol, Giuliani SpA, Milan, Italy) and 105 to receive 2.4 g/day, starting 2 weeks after surgery. The primary outcome was endoscopic recurrence, at 12 months after surgery. Three different degrees of endoscopic recurrence were evaluated (endoscopic scores: > 0, > 1 and > 2). The secondary outcome was clinical recurrence, defined as a Crohn's disease activity index of more than 150 points or an increase in the Crohn's disease activity index of 100 points or more. For statistical analysis, chi-square, Wilcoxon and Cox regression model tests were used, when appropriate. RESULTS Eighty-four patients in the 4.0 g/day group and 81 patients in the 2.4 g/day group were evaluable by endoscopy. Endoscopic recurrence of > 0 was significantly higher in the 2.4 g/day group than in the 4.0 g/day group (62% vs. 46%; P < 0.04). No difference was observed between the two groups with regard to the other two endoscopic outcomes (> 1 and > 2) or clinical recurrence. CONCLUSIONS A 4.0 g/day regimen of mesalazine does not offer a clinically significant advantage over a 2.4 g/day regimen in the prevention of post-operative endoscopic and clinical recurrence of Crohn's disease at 1 year of follow-up.

Abstract
New fluorescent ligands for adenosine receptors (ARs), obtained by the insertion, in the N(6) position of NECA, of NBD-moieties with linear alkyl spacers of increasing length, proved to possess a high affinity and selectivity for the A(3) subtype expressed in CHO cells. In fluorescence microscopy assays, compound 2d, the most active and selective for human A(3)-AR, permitted visualization and localization of this human receptor subtype, showing its potential suitability for internalization and trafficking studies in living cells.

Abstract
The phenolic "A-ring" of natural and synthetic estrogen receptor (ER) ligands was effectively replaced by a planar six-member ring formed through an intramolecular hydrogen bond within a salicylaldoxime. Thus, oxime 1, a structural analogue of a triarylethylene estrogen, showed a significant binding affinity for the ER. The OH of the oxime function appears to mimic the phenolic OH present in more "classical" ER ligands because the binding reduced when the oxime OH is methylated (2) or absent (3).

Abstract
BACKGROUND Death rate for patients with ulcerative colitis has changed over last few decades. Recent studies indicate that cumulative long-term mortality is comparable to that in general population, and that deaths may depend on causes not strictly related to colonic disease. AIM To evaluate overall and cause-specific mortality rate in a large group of Italian patients with ulcerative colitis. METHODS A total of 2,066 ulcerative colitis patients aged >18 years consecutively diagnosed in twenty Italian Gastroenterology Units between 1964 and 1995 were followed-up from diagnosis until 1997. Standardised Mortality Ratios and Relative Survival Ratios were calculated. RESULTS Overall mortality of patients with ulcerative colitis was comparable to that in general population with 93 deaths observed versus 92.1 expected (standardises mortality ratio, 1.0; 95% confidence interval, 0.8-1.2). Significantly higher mortality was observed in patients under 30 years of age at diagnosis (standardised mortality ratio, 2.7; 95% confidence interval, 1.3-4.9), and in those diagnosed before 1974 (standardised mortality ratio, 2.7; 95% confidence interval, 1.1-5.7). Proctocolitis and complications from surgery were mentioned in 11 and 5 certificates, respectively. A significant excess of deaths was observed for colorectal cancer (colon: standardised mortality ratio, 3.0; 95% confidence interval, 1.0-6.9; rectum: standardised mortality ratio, 4.4; 95% confidence interval, 1.2-11.3), and haemolymphopoietic neoplasms (standardised mortality ratio, 2.8; 95% confidence interval, 1.0-6.1), in particular multiple myeloma and non-Hodgkin lymphoma. A significant deficit of deaths was observed for cancer of the respiratory system (standardised mortality ratio, 0.3; 95% confidence interval, 0.1-1.0). CONCLUSIONS This study confirms that, also in Italy, mortality of patients with ulcerative colitis is comparable to that in general population. Only 12% of deaths were due to ulcerative colitis itself, whereas 10% of deaths were attributed to colorectal cancer. Deaths from colorectal cancer occurred, on average, 9 years after diagnosis of ulcerative colitis, suggesting that the risk of cancer is not limited to patients with long-standing colitis. As to mortality for causes unrelated to colitis, there was an excess of deaths due to malignancies of the haemolymphopoietic system.

Abstract
The present paper describes the methodological optimization and validation of a capillary zone electrophoresis method for the rapid determination of heroin, secondary products and additives present in clandestine heroin samples, by using 20 mM beta-cyclodextrins in phosphate buffer, pH 3.23. Applied potential was 15 kV and separation temperature was 24 degrees C; detection was by UV absorption at 200 nm wavelength. Heroin samples were first dissolved in CHCl3-MeOH (96:4, v/v) and injected by pressure (0.5 p.s.i., 3 s; 1 p.s.i.=6894.76 Pa) after evaporation of the organic mixture and reconstitution in aqueous buffer. Under the described conditions, phenylethylamine (internal standard), morphine, monoacetylmorphine, heroin, acetylcodeine, papaverine, codeine and narcotine were baseline resolved in less than 10 min. The limit of detection was better than 1 microg/ml for each analyte. The study of the intra-day and day-to-day precision showed, in terms of migration times, RSDs < or = 0.71% and, in terms of peak areas, RSDs < or = 3.2%. Also, the evaluation of linearity and analytical accuracy of the method provided good results for all the analytes investigated, thus allowing its application to real cases of seized controlled drug preparations.

Abstract
We have recently shown that open reading frame Rv1086 of the Mycobacterium tuberculosis H37Rv genome sequence encodes a unique isoprenyl diphosphate synthase. The product of this enzyme, omega,E,Z-farnesyl diphosphate, is an intermediate for the synthesis of decaprenyl phosphate, which has a central role in the biosynthesis of most features of the mycobacterial cell wall, including peptidoglycan, arabinan, linker unit galactan, and lipoarabinomannan. We have now purified Z-farnesyl diphosphate synthase to near homogeneity using a novel mycobacterial expression system. Z-Farnesyl diphosphate synthase catalyzed the addition of isopentenyl diphosphate to omega,E-geranyl diphosphate or omega,Z-neryl diphosphate yielding omega,E,Z-farnesyl diphosphate and omega,Z,Z-farnesyl diphosphate, respectively. The enzyme has an absolute requirement for a divalent cation, an optimal pH range of 7-8, and K(m) values of 124 micrometer for isopentenyl diphosphate, 38 micrometer for geranyl diphosphate, and 16 micrometer for neryl diphosphate. Inhibitors of the Z-farnesyl diphosphate synthase were designed and chemically synthesized as stable analogs of omega,E-geranyl diphosphate in which the labile diphosphate moiety was replaced with stable moieties. Studies with these compounds revealed that the active site of Z-farnesyl diphosphate synthase differs substantially from E-farnesyl diphosphate synthase from pig brain (Sus scrofa).

Abstract
The synthesis of the two enantiomers of 3-(3,4-dimethylphenyl)-1-propylpiperidine 1, a potent and selective D4 dopaminergic ligand, was performed. The 3-(3,4-dimethylphenyl)- 1-propylpiperidine with the R configuration showed an affinity for the D4 receptors 6-fold higher than the corresponding enantiomer with the S configuration. Furthermore, the (R)-1 enantiomer proved to be highly selective for D4 receptors with respect to D2-D3 receptors, with a Ki ratio higher than 25,000, while the (S)-1 enantiomer was about 100-fold less selective than the (R)-1 one.

Abstract
AIM To perform a meta-analysis to assess the effectiveness and safety of oral budesonide for inducing remission in active Crohn's disease and for preventing relapse in Crohn's disease with medically- or surgically-induced remission. METHODS All randomized, double-blind controlled trials involving oral budesonide therapy in Crohn's disease were retrieved from a Medline search, reviews articles or their bibliographies. Of 83 articles retrieved, 12 met the inclusion criteria. Data extraction was performed by three independent observers and scoring disagreements were resolved by consensus. RESULTS Six trials tested budesonide in active disease and six in quiescent disease. Budesonide was less effective than conventional corticosteroids for inducing remission of active Crohn's disease (pooled rate difference, RD -8.5%; 95% CI: -16.4 to -0.7%; P=0.02), but corticosteroid-related adverse events were reduced (RD -22.4%; 95% CI: -32 to -12.8%; P < 0.001). In quiescent Crohn's disease, budesonide was as effective as placebo for preventing relapse in medically induced remission (RD -0.8%; 95% CI: -9.9 to 8.3%; P=0.42) and endoscopic recurrence in surgically induced remission (RD -3.5%; 95% CI: -16.9 to 9.8%; P=0.30). In the long term treatment, budesonide had an occurrence rate of corticosteroid-related adverse effects similar to placebo (RD 5.3%; 95% CI: -3.9 to 14.5%; P=0.30). CONCLUSIONS Budesonide is significantly less effective than conventional corticosteroids for inducing remission in active Crohn's disease, but the risk of corticosteroid-related adverse effects is significantly reduced. Budesonide is not effective in preventing relapse of Crohn's disease after medically- or surgically-induced remission.

Abstract
Clinical-endoscopic parameters of UC presentation were studied in 1705 out-patients, observed consecutively in 17 Italian gastroenterology centers (males 60.2%; average age at diagnosis 38.5 +/- 16.4 years), and were subdivided arbitrarily into quartile age groups at diagnosis (0-25, 26-35, 36-50, >50). A significantly greater prevalence in males, increasing with age, was shown at diagnosis (P = 0.0002), which seems to correlate with the condition of being an ex-smoker, most frequently found in males. The greater frequency of exsmokers could also, in part, justify the second peak of incidence in old age. Greater colitis extent, greater clinical activity, and greater use of steroids as the first therapeutic step are shown to prevail among younger patients and among women (P = 0.02 and P = 0.019, respectively). The same is observed for symptoms mainly representing clinical severity such as diarrhea, fever, and weight loss (P = 0.004; P = 0.006; P = 0.009, respectively). This study confirms the UC risk factor represented by the condition of being an ex-smoker and shows a greater severity of illness on diagnosis in younger patients.

Abstract
Intestinal ischaemia is an uncommon complication of recreational cocaine abuse. We report the case of a 36-year-old male who underwent emergency surgery for acute abdomen. At laparotomy, the transverse colon appeared markedly oedematous, dilated and with subserosal haemorrhage. Segmental resection was performed and microscopic examination of the resected specimen showed focal necrosis of the mucosa with a patchy polymorphonuclear and mononuclear infiltrate. The submucosa was markedly thickened due to oedema; focal haemorrhage was observed and blood vessels were dilated but showed no structural abnormalities or thrombosis. These findings were consistent with ischaemic colitis. No risk factors for intestinal ischaemia were present but the patient stated that he had injected cocaine i.v. the day before the onset of symptoms. He was not a cocaine abuser but occasionally sniffed, smoked or injected cocaine. Cocaine use should be considered in the aetiological diagnosis of intestinal ischaemia in young patients.

Abstract
BACKGROUND Using data from a case-control study carried out in Italy 1989-1992, we estimated the odds ratios (OR) and the population attributable risks (AR) for inflammatory bowel diseases (IBD) in relation to smoking, oral contraception and breastfeeding in infancy. METHODS The study focused on 819 cases of IBD (594 ulcerative colitis: UC; 225 Crohn's disease: CD) originating from populations resident in 10 Italian areas, and age-sex matched paired controls. RESULTS Compared with non-smokers, former smokers were at increased risk of UC (OR = 3.0; 95% confidence interval [CI]: 2.1-4.3), whereas current smokers were at increased risk of CD (OR = 1.7; 95% CI: 1.1-2.6). Females who reported use of oral contraceptives for at least one month before onset of symptoms had a higher risk of CD (OR = 3.4; 95% CI: 1.0-11.9), whereas no significant risk was observed for UC. Lack of breastfeeding was associated with an increased risk of UC (OR = 1.5; 95% CI: 1.1-2.1) and CD (OR = 1.9; 95% CI: 1.1-3.3). Being a 'former smoker' was the factor with the highest attributable risk of UC both in males (AR = 28%; 95% CI: 20-35 %) and in females (AR = 12%; 95% CI: 5-18%). Smoking was the factor with the highest attributable risk for CD in males (AR = 31%; 95% CI: 11-50%). Lack of breastfeeding accounted for the highest proportion of CD in females (AR = 11%; 95% CI: 1-22%). Oral contraceptive use accounted for 7% of cases of UC and for 11% of cases of CD. CONCLUSIONS Taken together, the considered factors were responsible for a proportion of IBD ranging from 26% (CD females) to 36% (CD males). It is concluded that other environmental and genetic factors may be involved in the aetiology of IBD.

Abstract
BACKGROUND AND METHODS Four hundred and eighty-four patients with inflammatory bowel disease underwent clinical examination, ultrasonography, and biochemical liver function tests, to estimate the prevalence of hepatobiliary alterations. The patient group included patients without a history of liver disease. Controls were recruited from patients with functional symptoms. RESULTS More patients with ulcerative colitis than controls had liver steatosis and increased alkaline phosphatase levels. Factors increasing the probability of liver damage were long-standing disease, the presence of moderate/severe disease activity, and treatment with steroids and mesalazine. A significant association was found between biliary disease and long-standing colitis and also therapy with steroids and mesalazine. Alkaline phosphatase and aminotransferase levels were significantly higher in Crohn's disease patients than in controls. Hepatic and biliary damage was found more commonly in the 1st year after diagnosis. CONCLUSIONS The monitoring of hepatobiliary function is suggested for patients with inflammatory bowel disease, even in the absence of symptoms and history.

Abstract
Several activity indexes, including clinical variables, laboratory variables or both, have been proposed to assess the activity and severity of Crohn's disease (CD). Although activity indexes are commonly used in clinical trials, doubts exist as to whether it is correct to group together and quantify under the same numerical expression the very heterogeneous clinical manifestations of CD. The aim of our study was to try to establish a correlation between clinical and laboratory activity indexes of CD in subgroups of patients with primarily inflammatory or primarily fibrostenosing clinical characteristics. At least two activity indexes were calculated among 232 outpatient examinations in 61 CD patients. Indexes were classified as clinical, laboratory, or both. A close correlation was observed when indexes calculated on clinical variables were compared or when those that include only or prevalently laboratory parameters were compared. Conversely, the correlation between clinical and laboratory indexes tended to be poor. Taking into consideration the subgroups of patients, the correlation between clinical and laboratory indexes was high in primarily inflammatory disease but low in the primarily fibrostenosing form. The clinical activity of CD does not always reflect the quantity of inflammation measured by laboratory parameters. This is particularly true in primarily fibrostenosing disease. Different clinical patterns of CD should always be considered in the attempt to quantify with an activity index the activity and severity of disease.

Abstract
Carcinoid tumours are rare neoplasms and their behaviour seems to change with the localization; in fact, appendiceal and rectal carcinoids show a better long-term survival than the more aggressive ileal and colonic analogues. The Authors report their experience in the surgical treatment of 13 G.I. carcinoid neoplasms, in which the clinical course was sometimes unpredictable suggesting there is much to discover about the behaviour of these particular tumours.

Abstract
Thromboembolic disease is a well-recognized but very uncommon complication of inflammatory bowel disease. The mechanisms of the increased risk of thrombosis are not well understood: although several coagulation abnormalities have been described in inflammatory bowel disease patients, it is not clear whether they actually contribute to hypercoagulation or whether they are nonspecific markers of inflammation. Antiphospholipid antibodies (anticardiolipin antibodies and/or lupus anticoagulant) have recently been associated with an increased risk of thrombosis, particularly cerebrovascular disease in young patients. We report the case of a 33-yr-old female with severe ulcerative colitis at first attack who developed thrombosis of the superior and inferior longitudinal dural sinuses. No risk factors for thrombosis or coagulation abnormalities were observed; however, lupus anticoagulant was detected in the serum. The patient was successfully treated with osmotic agents, prophylactic anticonvulsant, and antiplatelet therapy, combined with i.v. steroids. After 6 months, the colitis is in remission, and the neurological recovery is good even if not yet complete.

Abstract
BACKGROUND Adhesion molecules play a major role in the pathogenesis of inflammatory skin diseases by regulating lymphocyte trafficking and homing in an inflamed area. METHODS The expression of the lymphocyte function-associated antigen-1 (LFA-1) and of its ligand, the intercellular adhesion molecule-1 (ICAM-1) has been studied in psoriatic skin lesions of 10 patients with guttate, nummular, and palmoplantar psoriasis. In addition, the peculiar immunophenotype of infiltrating cells (CD3, CD4, CD8, CD25) and their correlation with HLA-DR expression before and after treatment with oral cetirizine, a highly selective, third generation H1-receptor antagonist has been examined using the labeled avidin biotin (LAB) system. RESULTS Cetirizine treatment modulated in vivo the expression of adhesion molecules LFA-1/CAM-1 as shown in all cases by decreased levels of their expression on keratinocytes and on dermal endothelial cells (P < 0.001). The expression of HLA-DR on keratinocytes and endothelial cells was also inhibited after treatment. The numbers of infiltrating CD3-, CD4-, CD8-positive cells were reduced, whereas there was no significant modification of CD25-positive cells within the epidermis and the dermis. CONCLUSION This open clinical trial suggests that cetirizine could be effective in treating psoriasis: (1) for its symptomatic control on itching; (2) for its immunopharmacologic modulation of leukocyte integrins and on the immunophenotype pattern of infiltrating and resident cells, and (3) for contributing to the clearing of the lesions clinically.

Abstract
We describe this case of LEP for its unusual way of presentation. It first appeared with a LEP pattern, followed by a typical DLE of the skin, overlying the nodules only. Moreover, our histologic findings showed the typical pattern of lymphocytic lobular panniculitis, with hyaline necrosis of fat, the lymphoid nodule, and even the lymphocytic nuclear "dust." The epidermal changes, with the liquefaction degeneration of the basal cell layer, a moderate follicular hyperkeratosis, and a perivascular and periappendeal lymphocytic infiltrate, were also observed in the abdominal lesion that developed last without clinically evident DLE.

Abstract
BACKGROUND AND AIMS In a recent open trial we have shown the efficacy of long term intermittent administration of a poorly absorbable antibiotic (rifaximin) in obtaining symptomatic relief in uncomplicated diverticular disease of the colon. The aim of this double-blind placebo-controlled trial was to test our previous observations. METHODS One hundred and sixty-eight outpatients with symptomatic uncomplicated diverticular disease were treated with fibre supplementation (glucomannan 2 g/day) plus rifaximin 400 mg b.d. for 7 days every month (84 patients), or with glucomannan 2 g/day plus placebo two tablets b.d. for 7 days every month (84 patients). Clinical evaluation was performed at admission and at three-month intervals for 12 months. RESULTS After 12 months, 68.9% of the patients treated with rifaximin were symptom-free or mildly symptomatic, compared to 39.5% in the placebo group (P = 0.001). Symptoms such as bloating and abdominal pain or discomfort were primarily affected by antibiotic treatment when compared with placebo (P < 0.001). CONCLUSION Rifaximin appears to be of some advantage in obtaining symptomatic relief in diverticular disease of the colon when compared with fibre supplementation alone.

Abstract
Diverticular disease of the colon is a common health problem in western societies. Most patients with colonic diverticula are asymptomatic; it has been estimated that only 20% of individuals harboring diverticula will develop symptoms and signs of illness and a minority will develop major complications. Medical treatment of diverticular disease is aimed to the relief of symptoms and to prevent inflammatory complications. High fiber diets and antispasmodics are widely used in the treatment of uncomplicated diverticular disease although their real efficacy has not been fully elucidated. Antibiotics are used to treat major inflammatory complications of diverticular disease but apparently there is no rationale for their use in uncomplicated disease where an inflammatory component is, by definition, excluded. However two recent papers suggest a possible role of rifaximin, a broad-spectrum poorly absorbable antibiotic, in the management of mild acute diverticulitis and in obtaining symptomatic relief in patients with uncomplicated disease. Prospective studies with an adequate sample size per group of treatment are needed to assess the efficacy of cyclic long term administration of poorly absorbable antibiotics in preventing major complications of diverticular disease.

Abstract
The aim of the present study was to evaluate the role of sulglycotide, a molecule with gastroprotective properties, in monotherapy and in association with H2-antagonists in the maintenance treatment of duodenal ulcer. The study was performed using a fully randomized experimental design. Following endoscopic confirmation, 626 patients with healed duodenal ulcer were treated for 6 months with sulglycotide 200 mg tid (293 patients) or sulglycotide + H2-antagonists (333 patients). After 2, 4 and 6 months patients underwent a clinical control whereas an endoscopic control was performed after 6 months. The cumulative percentage of recidivation was 3.6% in the sulglycotide + H2-antagonist treated group, whereas the group treated with sulglycotide alone showed a recidivation rate of 15.4% (p < 0.001). These findings suggest the utility of combined sulglycotide and H2-antagonist treatment in the maintenance therapy for duodenal ulcer.

Abstract
The prevalence of erosive lesions was found to be 27.5% in 11838 cases examined during the last 10 years. In almost 66% of the cases, erosive lesions were localized in the duodenal bulb but mainly isolated and less often in the antro-pyloric area. In 55% of the cases, duodenal erosions coexist with ulcerative peptic disease, 20% in "active" phase and 35% in "inactive" phase. Erosive lesions, appeared autonomously in 45% of the cases. Morphologically, they can be divided in: a) periulcerative marginal erosions closely connected with activity of the ulcers; b) clustered, complete or incomplete erosions, which may or may not be associated with the ulcerative disease and often have a prolonged acyclic behaviour; c) scattered flat erosions which can at times be associated with the ulcerative peptic disease but are always related to a chronic widespread duodenitis. An epidemiological study was performed on 564 cases which were divided into 3 groups: a) cases with autonomous erosive disease; b) those with erosions associated with post-ulcerative scars; and c) those with erosions associated with active ulcers. The control group of 111 cases was characterised by duodenal active ulcers with no erosions. Statistical evaluation of the percentage differences between the 4 groups revealed that in duodenal erosive disease predisposing factors such as psychic temper, environmental and work conditions and eating habits are evident. In autonomous disease drug intake and spices and, to a less extent, alcohol and/or stress situations play a more important role. In erosions associated with an active ulcer, a dominant obsessive temper facilitated by a difficult family situation, bad eating habits and a great amount of smoking are prominent factors.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Segregation analysis of 996 families in which the gene for beta-thalassemia was segregating showed no distortion of expected Mendelian ratios. No appreciable frequency of sporadic cases was detected. It was suggested that segregation distortion is not a mechanism which contributes to the maintenance of polymorphism in the beta-thalassemia system in the population of the Ferrara area.
