RESUMEN

BACKGROUND: Colorectal cancer (CRC) is a major healthcare problem all over the world and screening is effective in reducing mortality and increasing survival. Since colonoscopy has a central role in faecal immunochemical test (FIT)-based CRC screening and surveillance, consistent quality measures are essential to ensure quality and outcomes. Nevertheless, screening modalities in clinical practice may differ according to the centers experience and the local availability of instrumentation and devices. AIMS: to assess the quality of endoscopic screening for CRC and adherence to international guidelines across Gastroenterology Departments in Italy. METHODS: All members of the Italian Society of Gastroenterology (SIGE) were invited to answer a web-based survey. RESULTS: Data from 64 hospitals from 17 Italian regions were analyzed. 32/64 (50.0%) were from northern, 12/64 (18.75%) from central and 20/64 (31.25%) from southern Italy. Each center is equipped with a median of 5.0 (3.5-7.0) endoscopists involved in CRC screening, 71.4% of which are gastroenterologists. After a positive FIT, most centers (93.8%) schedule a colonoscopy within 3 months. High-definition video endoscopy is routinely performed in 68.8% and chromoendoscopy in 53.1% of centers. Withdrawal time is ≥6 min in 79.9% and cecal intubation rate is ≥90% in 94.4% of departments. Finally, in 92.7% of centers adenoma detection rate (ADR) overcome the minimum standard of 25%. Analyzing the data by regional areas, a significant higher number of median endoscopic examinations/year (6500 vs 4000 and 3000, respectively, p = 0.024) and of endoscopists per center (6.5 vs 5.0 and 3.5, respectively, p < 0.001) has been registered in the northern compared to central-southern centers. CONCLUSIONS: Data from this survey show adequacy and good quality of endoscopic screening for CRC in Italy, highlighting, at the same time, relevant deficiencies and a discrepancy in procedural attitudes between the different centers. These findings call for a urgent action to overcome the shortcomings, refine and homogenize the behaviour of all screening centers in the national territory and improve the outcomes.

RESUMEN

BACKGROUND: Paraduodenal pancreatitis is a focal form of chronic pancreatitis that affects the groove area between the duodenum and the head of the pancreas. Consensus regarding surgical or nonsurgical management as the best treatment option is still lacking. METHODS: We retrospectively evaluated all patients managed for PP at The Pancreas Institute of the University Hospital Trust of Verona from 1990 to 2017. The outcomes of surgical vs. medical treatment with regard to pain control, quality of life and pancreatic insufficiency were evaluated through specific questionnaires. RESULTS: The final study population consisted of 75 patients: 62.6% underwent surgery, and 37.4% were managed without surgery. All surgical procedures consisted of pancreaticoduodenectomy. The median follow-up from the diagnosis of paraduodenal pancreatitis was 60 (12-240) months. Patients who underwent surgery experienced a similar incidence of steatorrhea (44.7 vs. 52.6%; p = 0.4) but a significantly higher incidence of diabetes (59.6 vs. 10.7%; p < 0.01) when compared to those managed without surgery. There was no difference in terms of reported chronic pain (Graded Chronic Pain Scale, median 0 vs. 1; p = 0.1) and quality of life (Pancreatitis QoL Instrument, median 82 vs. 79; p = 0.2). However, surgical patients reported a worse level of self-care activities associated with glycemic control (Diabetes Self-Management Questionnaire, median 20 vs. 28, p = 0.02). CONCLUSION: In patients affected by paraduodenal pancreatitis, surgery and medical therapy seem to obtain similar results in terms of quality of life and pain control. However, surgery is associated with an increased prevalence of postoperative diabetes with consequent relevant issues with self-care management. Surgery should be considered only in selected patients after adequate medical treatment.

RESUMEN

Systemic sclerosis (SSc) is an autoimmune disease which may lead to malnutrition. Previous studies have defined it with different criteria. No thorough evaluations of sarcopenia in SSc are available. The aim of the present study was to assess the prevalence and the potential association of malnutrition and sarcopenia in a large cohort of SSc cases. A total of 141 SSc consecutive outpatients were enrolled. Body composition was analyzed by densitometry. Malnutrition was defined according to recently published ESPEN criteria, whereas sarcopenia was diagnosed in patients with reduced skeletal muscle index. Malnutrition was diagnosed in 9.2% of patients (95% CI, 4.4-14.0%). Malnourished patients had worse gastrointestinal symptoms according to UCLA SCTC GIT 2.0 questionnaire (p = 0.007), lower physical activity (p = 0.028), longer disease duration (p = 0.019), worse predicted DLCO/VA and FVC (p = 0.009, respectively), worse disease severity according to Medsger severity score (p < 0.001), lower hemoglobin (p = 0.023), and fat-free mass (p < 0.001) and were more often sarcopenic (p < 0.001). In multivariate analysis, only FVC (p = 0.006) and disease severity (p = 0.003), in particular for the lungs (p = 0.013), were confirmed to be worse in malnourished patients. Sarcopenia was diagnosed in 29\140 patients (20.7%; 95% CI, 14.0-27.4%); 11\29 were also malnourished. In multivariate analysis, sarcopenic patients had longer disease duration (p = 0.049), worse DLCO/VA (p = 0.002), and lung (p = 0.006) and skin (p = 0.014) involvement. In SSc, malnutrition defined with ESPEN criteria was found to be lower than previously reported. Sarcopenia was found to be somewhat common. Lung involvement was significantly associated with nutritional status and may not be explained only by muscle weakness.

RESUMEN

BACKGROUND: The objectives of this study are to estimate prevalence and incidence of extrapancreatic malignancies (EPMs) among intraductal papillary mucinous neoplasms (IPMNs) of the pancreas, and to identify risk factors for their occurrence. PATIENTS AND METHODS: We conducted multicentric cohort study in Italy from January 2010 to January 2011 including 390 IPMN cases. EPMs were grouped as previous, synchronous (both prevalent) and metachronous (incident). We calculated the observed/expected (O/E) ratio of prevalent EPMs, and compared the distribution of demographic, medical history and lifestyle habits. RESULTS: Ninety-seven EPMs were diagnosed in 92 patients (23.6%), among them 78 (80.4%) were previous, 14 (14.4%) were synchronous and 5 (5.2%) were metachronous. O/E ratios for prevalent EPMs were significantly increased for colorectal carcinoma (2.26; CI 95% 1.17-3.96), renal cell carcinoma (6.00; CI 95% 2.74-11.39) and thyroid carcinoma (5.56; CI 95% 1.80-12.96). Increased age, heavy cigarette smoking, alcohol consumption and first-degree family history of gastric cancer are significant risk factors for EPMs, while first-degree family history of colorectal carcinoma was borderline. CONCLUSION: We report an increased prevalence of EPMs in Italian patients with IPMN, especially for colorectal carcinoma, renal cell and thyroid cancers. A systematic surveillance of IPMN cases for such cancer types would be advised.

RESUMEN

PURPOSE: This study prospectively assessed whether the presence of a bull's-eye pattern of pancreatic-duct stones on multidetector computed tomography (MDCT) correlated with gene-mutation-associated pancreatitis (GMAP) and whether other signs suggestive of GMAP can be detected with MDCT. MATERIALS AND METHODS: Forty-seven patients with chronic calcific pancreatitis underwent genetic testing for CFTR, SPINK1 and PRSS1 mutations and an MDCT scan of the abdomen. Qualitative analysis assessed the presence or absence of pancreatic-duct stones with bull's-eye appearance. Quantitative analysis included the number and maximum diameter of stones and the diameter of the main pancreatic duct. RESULTS: Fifteen of 47 patients (32%) were positive for gene mutations (GMAP patients). The bull's-eye pattern was found in 10/15 patients (67%) with GMAP and in 4/32 (12%) patients with chronic pancreatitis not associated with GMAP (NGMAP; p<0.0001). The mean diameter of duct stones was 15 mm in patients with GMAP and 10 mm in patients with NGMAP (p<0.04). CONCLUSIONS: The presence of duct stones with a bull's-eye pattern correlates with GMAP. Duct stones with diameter ≥15 mm are another sign suggestive of GMAP.

RESUMEN

PURPOSE: This retrospective study was done to correlate a quantitative assessment of the pancreatic exocrine reserve by dynamic secretin magnetic resonance cholangiopancreatography (MRCPQ) with the faecal elastase-1 (FE-1) test in patients with chronic pancreatitis. MATERIALS AND METHODS: Thirty-five patients with a clinical diagnosis of chronic (CP) or acute recurrent (ARP) pancreatitis were enrolled. FE-1 was indicative of the pancreatic exocrine reserve. Subsequently, the patient population was subdivided into two groups according to a clinical threshold value of 200 µg/g. All patients underwent MRCP examination during secretin administration. Duodenal filling volume was calculated on T2-weigthed rapid acquisition with relaxation enhancement (RARE) MRCP images obtained 10 min after secretin injection. Duodenal filling volumes were compared with FE-1 values. Scatter plots, Pearson correlation coefficient and the Mann-Whitney U test were performed. RESULTS: Thirty-five paired MRCPQ-FE1 data sets were analysed. MRCPQ was significantly different (p=0.007) between patients with impaired and preserved pancreatic function; median and interquartile range (IQR) were 150.7 ml (137.3-205.5 ml; n=9) and 332.4 ml (190.6-506.9 ml; n=26). Both Pearson correlation coefficient (p<0.001) and the Mann-Whitney U test (p=0.007) were significant. CONCLUSIONS: MRCPQ significantly correlates with FE-1 values. It is possible to discriminate impaired and preserved pancreatic exocrine function using MRCPQ.

RESUMEN

PURPOSE: The aim of this study was to review the computed tomography (CT) features of the pancreatic parenchyma and ducts in patients with gene-mutation-associated pancreatitis (GMAP). MATERIALS AND METHODS: Twenty-five patients with GMAP were included in this retrospective study. Patients were divided into two groups according to the time interval between the onset of symptoms and the first CT examination (group A ≤24 months and group B >25 months). RESULTS: On qualitative image assessment, in group A patients, pancreatic duct stones were detected in 2/13 with GMAP. All stones were calcified and homogenous. Enhancement of the pancreatic parenchyma was hypovascular in 7/13 patients. In group B patients, pancreatic duct stones were detected in 12/12 with GMAP. Stones were calcified in 10/12 cases and noncalcified (protein plugs) in 2/12; in 5/10 cases, the calcified stones were heterogeneous with noncalcified central core (bull's-eye appearance). Enhancement of the pancreatic parenchyma was hypovascular in 12/12 patients. On quantitative image assessment, in group A patients, the mean diameter of duct stones was 0.6 mm (range 0-5 mm). Mean diameter of the main duct in the pancreatic head and body/tail was 4.8 mm and 4.9 mm, respectively. In group B patients, the mean diameter of duct stones was 21.9 mm (range 2-50 mm). Mean diameter of the main duct in the pancreatic head and body/tail was 18.8 mm and 13.9 mm, respectively. CONCLUSIONS|: In patients with GMAP and time interval between symptom onset and first CT scan ≤24 months (group A), CT identified normal or slightly increased parenchymal thickness and a main pancreatic duct of normal calibre and without duct stones. In contrast, in patients with GMAP and time interval between symptom onset and first CT scan >25 months (group B), it identified large-calibre duct stones with bull's-eye appearance.

RESUMEN

Autoimmune pancreatitis is a form of pancreatitis with autoimmune stigmata that may present as either focal or diffuse gland involvement. In focal forms, autoimmune pancreatitis shares demographic, clinical, biochemical and imaging features with pancreatic cancer. Since autoimmune pancreatitis is a benign disease and steroid therapy can rapidly resolve symptoms, improve radiological findings and avoid unnecessary surgery, the current clinical challenge is how to differentiate autoimmune pancreatitis from pancreatic neoplasia. Even though definitive diagnosis of the disease is difficult, several diagnostic criteria have been proposed and progress has been made in imaging studies. The management of this unique form of pancreatitis should, therefore, be handled in centres with knowledge of all aspects of the disease. This article briefly reviews clinical aspects of autoimmune pancreatitis with a focus on its diagnostic imaging and management.

RESUMEN

PURPOSE: This study retrospectively determined magnetic resonance (MR), MR cholangiopancreatography (MRCP) and secretin-MRCP findings in patients with autoimmune pancreatitis (AIP). MATERIALS AND METHODS: The MR examinations of 28 patients with histopathologically proven AIP were reviewed. In 14 cases, secretin-enhanced MRCP was performed. The observers evaluated pancreatic parenchymal enlargement, signal intensity abnormalities, enhancement, vascular involvement, bile-duct diameter and main pancreatic duct (MPD) narrowing (diffuse/focal/segmental). After secretin administration, the presence of the "duct-penetrating" sign was evaluated. RESULTS: MR imaging showed diffuse pancreatic enlargement in 8/28(29%) cases, focal pancreatic enlargement in 16/28 (57%) cases and no enlargement in 4/28 (14%) cases. The alteration of pancreatic signal intensity was diffuse in 8/28 (29%) cases (eight diffuse AIP) and focal in 20/28 (71%) cases (20 focal AIP). Delayed pancreatic enhancement was present in all AIP, with peripheral rim of enhancement in 8/28 (29%) AIP (1/8 diffuse, 7/20 focal); vascular encasement was present in 7/28 (25%) AIP (1/8 diffuse, 6/20 focal); distal common bile duct narrowing was present in 12/28(43%) AIP (5/8 diffuse, 7/20 focal). MRCP showed MPD narrowing in 17/28 (61%) AIP (4/8 diffuse, 15/20 focal), MPD dilation in 8/28(29%) AIP (3/8 diffuse, 5/20 focal) and normal MPD in 1/8 diffuse AIP. Secretin-MRCP showed the duct-penetrating sign in 6/14(43%) AIP (one diffuse AIP with MPD segmental narrowing, five focal AIP with MPD focal narrowing), demonstrating integrity of the MPD. CONCLUSIONS: Delayed enhancement and MPD stenosis are suggestive for AIP on MR and MRCP imaging. Secretin-enhanced MRCP is a problem-solving tool in the differential diagnosis between focal AIP and ductal adenocarcinoma.

RESUMEN

BACKGROUND: Cystic dystrophy of heterotopic pancreas, groove pancreatitis, pancreatic hamartoma of the duodenum, paraduodenal wall cyst, and myoadenomatosis are all terms grouped together, from a pathological viewpoint, as definitions of paraduodenal pancreatitis (PP). The objective of the present study was to investigate the clinical characteristics, therapeutic strategies, and results in 58 patients undergoing pancreatic resection for PP. METHODS: From January 1990 to December 2006 data were prospectively collected on 58 patients who were diagnosed with PP who then underwent pancreaticoduodenectomy. RESULTS: In this patient cohort the median age was 44.7 years; only 4 patients were women, and only 3 had non-drinker and/or non smoker habits. The overall morbidity was 18.9%, and the median hospitalization was 11 days. There were no postoperative deaths. In a median follow-up of 96.3 months, all patients noted a decrease in the pain associated with PP; 35 patients (76%) had complete disappearance of pain, whereas occasional relapsing pain occurred in the remaining 11 (24%). CONCLUSIONS: Patients with PP have clinical characteristics similar to those of chronic pancreatitis. The diagnostic imaging modalities of choice are ultrasonographic endoscopy and magnetic resonance cholangiopancreaticography. Based on our surgical experience, pancreaticoduodenectomy seems to be a reasonable choice of treatment in patients with PP.

RESUMEN

BACKGROUND: No data on chronic pancreatitis in Italy are available yet. AIM: To evaluate demographic, clinical, diagnostic and therapeutic aspects in patients suffering from chronic pancreatitis. PATIENTS AND METHODS: Eligible patients were prospectively enrolled from 2000 to 2005. Information concerning demographic data, lifestyle risk factors, family and clinical history, associated factors (alcohol, autoimmunity, cystic dystrophy of the duodenal wall, obstruction, genetic mutations) concomitant diseases, diagnostic findings, and pharmacological, endoscopic and surgical therapy were gathered. RESULTS: 893 patients (74% males, mean age 53.7+/-15.2 years) were evaluated. 519/859 patients (60%) were drinkers and 555/840 (66%) were smokers. A strong positive correlation between drinking and cigarette consumption (R=0.53; p<0.0001) was found. Heavy alcohol consumption (>80g of alcohol/day for more than 5 years) was considered the most important risk factor in 300 patients (34%), obstruction in 238 (27%), alcohol and obstruction in 82 (9%), autoimmunity in 34 (4%), cystic dystrophy of the duodenal wall/groove pancreatitis in 55 (6%), gene mutations in 36 (4%), and none (idiopathic) in 148 (17%). Bile stones were diagnosed in 287 patients (33%) and cholecystectomy was performed in 329 patients (38%). Pancreatic calcifications were diagnosed in 547/879 patients (62%). Pancreatic surgery was performed in 273 patients (31%). Endoscopic sphincterotomy was performed in 371 patients (42%). Exocrine and endocrine insufficiency were found, respectively, in 373/834 (45%) and 275/885 patients (31%). CONCLUSIONS: An unexpected low frequency of alcohol abuse and new emerging associated risk factors for chronic pancreatitis were observed in Italy.

RESUMEN

BACKGROUND AND OBJECTIVES: Bacterial flagellin is considered an important antigen in Crohn's disease (CD) as it activates innate immunity through Toll-Like Receptor 5 (TLR5) engagement and induces an elevated adaptive immune response. Little is known about the presence of an autoimmune process in CD. We aimed to identify pathogenically relevant autoantigen targets in CD. METHODS: We screened a random peptide library with pooled sera of patients with active CD. Transepithelial flux of [3H] mannitol in T84 human intestinal epithelial cell line was used to study the epithelial barrier function. Monocyte activation was evaluated by surface expression of activation markers and by production of pro-inflammatory cytokines. Gene modulation of T84 cells exposed to antipeptide antibodies was analysed by gene array. RESULTS: We identified a peptide that shares homology with Salmonella typhimurium flagellin and with self-antigens such as TLR5 and cell junction protein, Pals 1-associated tight junction protein. The affinity-purified antipeptide antibodies recognized the self-antigens and induced increased intestinal epithelial cell permeability. Moreover, the antibodies induced monocyte activation upon binding TLR5. Finally, in cultured intestinal cells (T84) the purified antibodies induced the modulation of clusters of proinflammatory genes similar to the one induced by the engagement of TLR5 by its natural ligand flagellin. CONCLUSIONS: Antibodies directed against an immunodominant peptide of flagellin recognize self-antigens and are functionally active suggesting the presence of an autoimmune process that can both facilitate loss of tolerance to intestinal microflora by increasing cell permeability and amplify the innate immunity involvement through a novel mechanism of TLR5 activation.

RESUMEN

This medical position statement has been developed by the board of ProInf AISP (Computerized Project on Acute Pancreatitis) Study Group. The evidence and key recommendations were discussed at a dedicated meeting held in Milan on September 2007 and during this meeting the main clinical and therapeutic medical topics were extensively discussed. Each of the proposed recommendations was discussed and an initial consensus was reached. Acute pancreatitis in Italy is a disease of increasing annual incidence. The diagnosis of the disease should be established within 48hours of admission. Early identification of patients at risk of developing a severe attack of acute pancreatitis is of great importance because rapid therapeutic interventions improve outcome. The endoscopic approach seems to be most beneficial measure in patients with acute pancreatitis with jaundice and in those with cholangitis. The development of infected necrosis should be assessed using fine-needle aspiration and the sample should be cultured for germ isolation and characterization. The role of early ERCP in all patients with severe acute pancreatitis of biliary origin is still controversial. The data supporting the efficacy of antibiotic prophylaxis to prevent infection of necrosis are conflicting. The refeeding is a crucial topic in patients who have recovered from an acute episode of mild acute pancreatitis, but there are very few studies on this issue.

RESUMEN

BACKGROUND AND AIM: Up till now, only one study providing practically complete information on acute pancreatitis in Italy has been published. The aim of this prospective study was to evaluate the clinical characteristics, in terms of diagnostic assessment and outcome, of a large series of patients affected by acute pancreatitis in Italy. MATERIALS AND METHODS: The study involved 56 Italian centres, homogeneously distributed throughout the entire national territory. Each participating centre was furnished with an ad hoc software including 530 items along with subsequent collection, tabulation and quality control of the data. RESULTS: One thousand five hundred and forty case report forms of patients affected by acute pancreatitis were collected but 367 of them (24%) were subsequently eliminated from the final analysis. Therefore, 1173 patients (581 females and 592 males) were recruited. Mean age of patients was 62.0+/-18.2 years (95% confidence interval, 60.9-63.0). On the basis of Atlanta classification, 1006 patients (85.8%) were defined as mild and 167 (14.2%) as severe pancreatitis. Biliary forms represented the most frequent aetiological category (813 cases, 69.3%) while alcoholic forms only 6.6% (77 cases); the remaining aetiologies accounted for 7.1% (83 cases) while 200 cases (17.1%) remained without a definite aetiological factor. Complete recovery was achieved in 1016 patients (86.6%) whereas morphological sequelae were found in 121 patients (10.3%) and mortality in 36 patients (3.1%; 0.4% in mild and 19.2% in severe acute pancreatitis). Ultrasonography was largely utilised as a first line diagnostic tool in all patients, with valuable visualisation of the pancreas in 85% of patients. Computer tomography scan was also widely used, with 66.7% of exams in mild and 33.3% in severe pancreatitis. Patients affected by biliary pancreatitis presented more severe (p=0.004) and necrotizing forms (p=0.021). Mortality was significantly related (p<0.001) with the extension of pancreatic necrosis and with an age of over 70 years. Body mass index presented significantly greater values in severe than in mild forms (p<0.001). CONCLUSIONS: Association of creatinine serum level over 2mg/dl with an abnormal chest X-ray showed a high significant correlation with a more severe outcome in terms of morphological sequelae and mortality (p=0.0001). Acute pancreatitis in Italy more commonly presents biliary aetiology and favourable outcome with low rate of complications and mortality. From a cost-effectiveness standpoint, diagnostic approach to this disease needs to be better standardised.

RESUMEN

BACKGROUND: The Italian Association for the Study of the Pancreas released a diagnostic and therapeutic algorithm for acute pancreatitis in 1999. AIM: This study focused on the analysis of the therapeutic approach for the treatment of acute pancreatitis in Italy. PATIENTS: One thousand, one hundred and seventy-three patients were recruited: 1006 patients (85.8%) had mild acute pancreatitis (MAP) and 167 (14.2%) had the severe acute pancreatitis (SAP); 161 patients showed pancreatic necrosis at computed tomography; 121 patients (10.3%) had sequelae and 36 (3.1%) died. RESULTS: Non-steroidal anti-inflammatory drugs and tramadol were used more frequently in patients with the MAP whereas opioids and the association schedules were used more frequently in patients with the SAP (P<0.001). Gabexate mesilate was utilised in 831 out of 1173 patients (70.8%); in particular, gabexate mesilate was used in 70.6% patients with MAP and in 73.1% of those with SAP (P=0.521). The duration of the drug administration was significantly shorter in those having MAP than in those having the SAP (P<0.001). The antibiotics most frequently used for the prophylaxis against infection from pancreatic necrosis (43.1%) were carbapenems. Only a small number of patients received enteral nutrition (4.7%). Endoscopic retrograde cholangiopancreatography was carried out in 344 of the 1173 patients (29.3%). Surgery was performed in 48 with SAP (19 had elective biliary surgery and 29 had pancreatic surgery). CONCLUSIONS: The results of this survey indicate a lack of compliance with the guidelines which regard the indications mainly for interventional endoscopy and surgery.

RESUMEN

BACKGROUND: The effect of native somatostatin on Sphincter of Oddi motility still remains controversial. Sphincter of Oddi inhibition was demonstrated at manometry in patients in the acute phase of alcoholic pancreatitis. Other investigators showed marked somatostatin-induced impairment of bile flow by hepato-biliary scintigraphy. AIM: Aim of the study was to determine the effects of therapeutical doses of exogenous somatostatin on Sphincter of Oddi motility. PATIENTS AND METHODS: We studied eight patients (two men, six women, age 18-42), in the quiescent phase of idiopathic recurrent pancreatitis. We directly studied Sphincter of Oddi motility by perendoscopic manometry and, indirectly, secretin-stimulated pancreatic juice outflow by Ultrasound-Secretin test. The two tests were repeated before and after somatostatin infusion. RESULTS: Manometry was performed in two patients. After 250 microg somatostatin bolus the sphincter showed an increase of motor activity. At Ultrasound-Secretin test mean diameters were significantly larger at 40-60 min evaluation intervals during 250 microg/h somatostatin infusion as compared to saline infusion, showing a delayed pancreatic duct emptying. CONCLUSIONS: Acute administration of somatostatin seems to induce an excitatory effect on Sphincter of Oddi motility, with impaired pancreatic outflow in patients in the quiescent phase of recurrent pancreatitis.

RESUMEN

AIM: It is still debated whether clinical flare-ups of chronic inflammatory bowel disease follow a seasonal pattern, and the various reports are based on general practitioners' records or hospital discharge charts. There are, however, no specific figures for treatment in hospital gastroenterology units, which serve as a reference point for these disorders. This study was therefore designed to investigate whether there is a seasonal pattern in admissions for inflammatory intestinal disease in Italy, differing from what is generally known about gastrointestinal pathologies, since there are no nation-wide figures on the subject. METHODS: The RING (Ricerca Informatizzata in Gastroenterologia) project is an observational study collecting hospital discharge forms from 22 centers in Italy. RESULTS: From winter 2000 to autumn 2003, the 22 gastroenterology units participating in the RING project discharged 32,357 patients following ordinary hospital admissions. Of these, 2,856 (8.8%) had a main diagnosis of inflammatory bowel disease: 1,541 Crohn's disease, and 1,315 ulcerative colitis. No seasonal patterns were detected for either category, or when the analysis was done by age, sex and site of disease. CONCLUSIONS: The most serious flare-ups of inflammatory bowel disease, i.e. those requiring routine hospital treatment, do not appear to follow any seasonal pattern, regardless of the site of the disease or the patient's age or sex.

RESUMEN

BACKGROUND: In clinical practice there is the need to utilise a time saving questionnaire to assess the quality of life. AIMS: To establish the validity of the SF-12 questionnaire in chronic pancreatitis patients and to identify the predictors capable of modifying the physical and mental summaries in these patients. QUESTIONNAIRES: SF-12 and SF-36 questionnaires were used. SUBJECTS: One hundred and forty-one outpatients with proven chronic pancreatitis. The data of 141 sex- and age-matched Italian subjects of two normative groups (61,434 Italian subjects for SF-12 and 2031 Italian subjects for SF-36) were used as controls. RESULTS: Chronic pancreatitis patients had the SF-12 physical and mental component summaries significantly related to the SF-36 physical and mental component summaries (P<0.001). The presence of pancreatic pain and non-pancreatic surgery accounted for 41.3% in the formation of the PCS-36 score and 37.2% in that of the PCS-12 score, respectively. Gender, BMI and pancreatic pain accounted for 15.3% of the information in the formation of the MCS-36 and for 14.7% in that of the MCS-12; using these clinical variables, the loss of information in applying the SF-12 instead of the SF-36 was very low (4.1 and 0.6% for the PCS and the MCS, respectively). CONCLUSIONS: The SF-12 is a good alternative to the SF-36 in assessing the quality of life in chronic pancreatitis.
