Abstract
The nonstenotic, nonfistulizing (or inflammatory) pattern of Crohn's disease appears to be unstable in time and may evolve toward either the stenotic or the fistulizing pattern. We aimed to assess the course of the inflammatory disease and its relation to certain clinical characteristics. After a mean follow-up of 93 months, we evaluated 73 patients with an inflammatory pattern. The behavior trend and its relation to disease location, initial treatment, and need for corticosteroids, immunosuppressors, and surgical resection were analyzed. In 64% of the patients the inflammatory pattern did not change, while in 14 and 22% it evolved toward a stenotic and a fistulizing pattern, respectively. This change was mainly determined by the appearance of perianal disease (75%). The mean time to behavior evolution was 67 months. Most patients required corticosteroids (92%). Need for immunosuppressors (48%) and surgical resection (30%) was significantly greater (P < 0.05) among patients with a change in pattern than in those with persistent inflammatory disease. The inflammatory pattern of CD remains stable in about half of patients. The course of this pattern is not indolent, however, since the needs for immunosuppression and surgical resection during follow-up are considerable.

Abstract
On-demand therapy is effective for maintaining symptoms control in nonerosive gastroesophageal reflux disease (GERD). Our aim was to assess the clinical effectiveness of on-demand therapy with a proton pump inhibitor (PPI) in mild GERD (nonerosive and low-grade esophagitis), its impact on health-related quality of life (HRQoL), and the degree of patient satisfaction. Fifty-five patients (17 with nonerosive GERD and 38 with low-grade esophagitis) were treated with rabeprazole, 20 mg/day. The healed patients started on-demand therapy. We evaluated symptoms (clinical questionnaire), HRQoL (SF-36 questionnaire), and patient satisfaction (visual analogue scale). Of the 55 patients included, 51 started on-demand therapy for 6 months. Symptom control (heartburn <twice a week) was achieved in over 85% of the patients. The mean (SD) amount of PPI used was 0.3 (0.19) tablet/day. The patient satisfaction score at the end of the acute phase was 98 (range, 0-100) and remained high (90; range, 10-100) and stable during on-demand therapy. Short-term treatment normalized the HRQoL scores, which were subsequently maintained during on-demand therapy. On-demand therapy is useful for the clinical management of patients with mild GERD, allowing adequate symptoms control, limiting PPI consumption, and affording important patient satisfaction with normalization of HRQoL.

Abstract
Acalculous biliary pain has been related to gallbladder dysfunction that produces a gallbladder emptying defect-a condition which favours the development of lithiasis. It is therefore probable that microlithiasis is present in patients with gallbladder dysfunction. The aims of this study were to measure gallbladder emptying and investigate bile abnormalities in patients with acalculous biliary pain. In 92 consecutive patients, gallbladder emptying was assessed by quantitative cholescintigraphy (abnormal ejection fraction < or =40%). In 64 patients, a microscopic study was performed on duodenal bile, defining abnormality as the presence of cholesterol crystals in any amount and/or calcium bilirubinate granules and/or microspheroliths at a rate of >10 per slide. The ejection fraction was abnormal in 45 patients (49%) (median 25.1%, range 6.8-39.3%) and normal in the remaining 47 cases (median 71.3%, range 41.0-96.1%). Bile was abnormal in 32 of 64 patients (50%), the most frequent finding being calcium bilirubinate granules. In the patients with bile abnormalities, abnormal ejection fraction was more frequent (20 of 32) and the median ejection fraction was lower (30.9%, range 12.0-94.1%) than in the patients with normal bile (16 of 32 with an abnormal ejection fraction; median ejection fraction 50.7%, range 6.8-96.1%). Abnormal bile was frequent (55.5%) in patients with reduced ejection fraction, but was not uncommon in patients with normal ejection fraction (33.3%). Fewer patients showed no alteration (25%). It is concluded that in most patients, acalculous biliary pain coexists with gallbladder dysfunction or abnormal bile, the combination of both alterations being common.

Abstract
The aims of this study were to estimate the prevalence of chronic constipation and to evaluate the diagnostic accuracy of the symptoms and the self-reported definition of constipation. A cross-sectional survey was conducted in the general community in 1999. A questionnaire comprising 21 items was developed and mailed to a random sample of 489 subjects who were aged between 18 and 65 years and who belonged to a Spanish population. In the 349 subjects (71%) responding to the questionnaire, the prevalence of self-reported constipation was 29.5% (95% confidence interval (CI): 24.9, 34.3) versus 19.2% (95% CI: 15.1, 23.3) and 14.0% (95% CI: 10.4, 17.7) based on Rome I and Rome II criteria, respectively. Agreement was good between self-reported and Rome I criteria (kappa: 0.68) and between Rome I and Rome II criteria (kappa: 0.71), and it was moderate between self-reported and Rome II criteria (kappa: 0.55). Female gender was identified to be a risk factor for constipation; fiber intake and physical exercise were found to be protective factors. Likelihood ratios were higher for the presence of anal blockage and straining and for the absence of hard stools. Chronic constipation is a highly prevalent problem, especially in women. Different prevalence estimates of constipation were observed using different criteria, although agreement between them was acceptable. Anal blockage, straining, and hard stools show the greatest accuracy for the diagnosis of constipation.

Abstract
OBJECTIVES Diagnosis of irritable bowel syndrome (IBS) and other functional bowel disorders (FBD) is based on symptom evaluation. Clinical criteria have changed over time, yielding different proportions of subjects fulfilling diagnostic requirements. According to new diagnostic criteria (Rome II), subjects considered some years ago to have IBS no longer do so. The aim of this article is to evaluate how patients diagnosed as having IBS according to original Rome criteria have been split, and to which clinical diagnosis they belong today. METHODS Two hundred and eleven subjects meeting original Rome IBS diagnostic criteria were studied: 65 also met Rome II criteria while 146 did not. Subjects were extracted from an epidemiological survey, using home-based personal interviews, on 2000 subjects randomly selected as representative of the Spanish population. Clinical complaints, personal well-being, resource utilization, and health-related quality of life (HRQOL) were compared. RESULTS Of the subjects meeting original Rome but not Rome II criteria, the present diagnosis should be: 40%"minor" IBS (IBS symptoms of less than 12 wk duration), 37% functional constipation, 12% alternating bowel habit, 7% functional diarrhea, 3% functional abdominal bloating, and 1% unspecified functional bowel disorder (FBD). Thus, 52 subjects (36%) should not be diagnosed with IBS because they really had other FBD, 59 (40%) because of symptoms consistent with IBD diagnosis but not the required duration or frequency, and 35 (24%) because of symptoms consistent with some other FBD diagnosis but not meeting the required duration. Clinical complaints, personal well-being, resource utilization, and HRQOL were more severely affected in IBS than in other FBD as a group, and in "major" rather than in "minor" forms. CONCLUSIONS Many subjects meeting original Rome criteria for IBS do not meet Rome II criteria: approximately one quarter of subjects do not have sufficient symptom duration or frequency to be diagnosed with IBS and almost half are now considered as having other ("major" or "minor") FBD.

Abstract
INTRODUCTION Crohn's disease shows periods of exacerbation and remission. Corticosteroids are the most frequently used drugs in exacerbations of disease activity. The objective of this study is to determine which clinical and laboratory parameters are associated with the therapeutic decision to administer corticosteroids during the course of the disease. MATERIAL AND METHOD Two-hundred seven consecutive visits made by 62 patients with Crohn's disease were selected from a database. Data from visits in which corticosteroid administration was initiated (n = 65) were compared with those from visits in which this decision was not made (n = 142). Univariate and multivariate (logistic regression) analyses were performed. The results are expressed as odds ratio (OR) with 95% confidence interval (95% CI). RESULTS In the univariate analysis statistically significant differences were found between groups in localization, maintenance treatment, Crohn's Disease Activity Index (CDAI) score, the presence of abdominal pain, mass, perianal disease, extraintestinal manifestations and all laboratory parameters (leukocytes, platelets, fibrinogen, erythrocyte sedimentation rate, C-reactive protein). In the multivariate analysis (with corticosteroid administration as the dependent variable) a statistically significant positive association was found between the decision to administer corticosteroids and mild (OR = 31.9; 95% CI, 6.6-154.1), moderate or severe (OR = 49.7; 95% CI, 6.1-401.3) CDAI, ileocolic localization (OR = 4.8; 95% CI, 1-22.1) and the presence of perianal disease (OR = 7.4; 95% CI, 1.5-35.9), while a negative association was found with maintenance treatment with immunosuppressant drugs (OR = 0.05; 95% CI, 0.30-0.008). The laboratory variables positively associated with corticosteroid administration were C-reactive protein and leukocyte count. CONCLUSION The variable with greatest predictive value for corticosteroid prescription is the CDAI score, although other clinical and laboratory variables not included in this index are also associated with corticosteroid administration. There is a negative association between the use of immunosuppressive drugs and corticosteroid prescription.

Abstract
HYPOTHESIS AND OBJECTIVES the hypothesis of this study is that genes involved in the regulation of the immune system, expressed by HLA antigens and anti-neutrophil cytoplasmic antibodies (ANCA), could be determinants of disease susceptibility and behavior in inflammatory bowel disease (IBD). MATERIAL AND METHOD seventy patients with a diagnosis of inflammatory bowel disease, 46 with ulcerative colitis and 24 with Crohn"s disease were included. HLA class I (A and B) and II (DR) antigens were studied by serological techniques. Detection of ANCA was carried out in all patients by an indirect immunofluorescence method. The relative frequencies of HLA antigens were compared with a control group made up of 156 blood donors. The control group for the ANCA study was made up of 100 individuals. RESULTS we found a significant increased frequency of HLA-DR2 in patients with ulcerative colitis. No significant differences were found between patients with Crohn"s disease and controls regarding HLA typing. We detected a significant increase of HLA-DR3 in extensive forms of ulcerative colitis. Detection of ANCA was positive in 46% of the patients with ulcerative colitis and in 12% of the patients with Crohn"s disease (p <0.05). We observed an increased frequency of ANCA in patients with UC and HLA-DR2 (p = 0.15). CONCLUSIONS the association found between HLA-DR3 and extensive forms of ulcerative colitis provides evidence of genetic heterogeneity. The relationship between ANCA and HLA phenotype (although not significant) supports this concept.

Abstract
Our aims were to describe clinical characteristics of patients with chronic posterior laryngitis and to predict the response to omeprazole therapy. Ninety-one patients with posterior laryngitis were evaluated by a questionnaire, esophageal manometry and pH recording, and endoscopy. Patients were treated with omeprazole, 20 mg twice daily for 3 months. Therapy was continued another 3 months if necessary. Clinical manifestations of reflux occurred in 84 (92%) patients, abnormal acid reflux in 53 (65%) cases, and esophagitis in 6 of 50 (12%). After 3 months of therapy significant improvement occurred in 30 of 70 patients (41%). Continuing therapy for 3 more months increased the response to 65% (45 of 69 cases). Response to therapy was associated with lower age and lower duration of laryngeal symptoms, but a consistent prediction of the response could not be made. In conclusion, patients with posterior laryngitis frequently present with manifestations of gastroesophageal reflux. Response to therapy can not be predicted with certainty.

Abstract
OBJECTIVE to develop a predictive model based on clinical data for patients with suspected upper digestive tract disease. PATIENTS AND METHODS forty-seven clinical data were obtained before endoscopy from 283 patients with suspected upper digestive disease (153 men; mean age 55 years, limits 17-92 years). A clinical prediction of diagnosis was made before endoscopy. On the basis of the endoscopic findings, the patients were divided into three diagnostic groups: absence of significant disease (group I), significant benign disease (group II) and malignant disease (group III). The probability rate of belonging to each one of the three groups was obtained for each patient by using Bayes' theorem. RESULTS the endoscopic findings were classified according to their clinical importance: 121 patients (43%) belonged to group I, 137 (48%) were included in group II; and 25 (9%) in group III. The clinical prediction correctly classified 61% of the patients (group I: 56%, group II: 62% and group III: 76%) The coincidence between prediction obtained using Bayes' theorem and the actual diagnosis was 61% (group I: 65%, group II: 51%, group III: 92%). The predictive model was useful to confirm or not the clinical prediction. CONCLUSION objective analysis of clinical data can be useful to support clinical judgment, mainly in patients with neoplasia. However, the model is not adequate to improve indication of upper endoscopy since many patients are misclassified.

Abstract
BACKGROUND Cardiomyotomy, often associated with an antireflux technique, is effective in the management of achalasia, although gastroesophageal reflux (GER) may occur after the procedure. Patient-centered measures, ie, health-related quality of life (HRQoL) and satisfaction, should be included in the evaluation of the patients. METHODS A study was made of the incidence of GER (symptoms, upper endoscopy and 24-hour pH monitoring), HRQoL (Short Form-36 Health Survey), and satisfaction after open-access cardiomyotomy and 180-degree anterior fundoplication in 28 consecutive patients, with a minimum postoperative follow-up of 12 months. RESULTS Mean age was 45 years (range 15 to 80) and 68% were female. In 8 subjects (all with heartburn) GER morbidity was present (4 with esophagitis and 4 with positive pH study), and 6 patients required proton pump inhibitors. Short Form-36 scores after surgery were similar to those found in the general population. Patient satisfaction was high and was more related to the absence of dysphagia than to the presence of GER symptoms. CONCLUSIONS Gastroesophageal reflux is relatively frequent after cardiomyotomy and partial fundoplication, although the efficacy of proton pump inhibitor treatment minimizes its clinical significance.

Abstract
We studied the influence of the inflammatory state of the gallbladder with gallstones on its response to cholecystokinin (CCK). Responses to CCK were evaluated in isolated human gallbladder strips incubated with pharmacological antagonists. Gallbladders from patients with gallstones were classified as having mild and severe chronic cholecystitis. Healthy gallbladders were collected from liver donors. In donor gallbladders, the CCK contraction was abolished with the CCK-A receptor antagonist, L-364718, and significantly reduced by indomethacin. In gallbladders with gallstones, only mild cholecystitis showed a decreased contraction to CCK. In gallbladders with gallstones, no involvement of prostaglandins in the CCK response was observed. In severe cholecystitis, CCK contractile effect was reduced by the serotonin receptor antagonist methysergide. In healthy gallbladder, the contraction provoked by CCK is mediated by CCK-A receptors and modulated by prostaglandins. The presence of gallstones in the gallbladder is correlated with a loss of prostaglandins-modulated CCK contraction. However, the excessive release of serotonin in advanced cholecystitis normalizes the contraction to CCK, suggesting that the state of cholecystitis affects the pool of inflammatory mediators responsible for gallbladder CCK-altered motility.

Abstract
OBJECTIVES To assess the utility of capsaicin test in the differential diagnosis of non-productive causes of chronic cough and to examine the effects of treatment on this reflex. PARTICIPANTS 86 healthy volunteers and 101 patients with chronic cough: asthma (n: 54) gastroesophageal reflux (n: 35) and post-nasal drip syndrome (n: 12). DESIGN Prospective intervention trial. Spirometry, bronchoprovocation test with histamine (PC20), and cough challenge with ascending concentrations of capsaicin (0.49-500 microM) were initially performed in all subjects. Patients were treated for 3 months according to the origin of the cough. Concentrations that elicited two (C2) and five or more coughs (C5) were determined before and after treatment. RESULTS In healthy subjects, cough sensitivity to capsaicin was not influenced by gender or smoking status; however, women with chronic cough were more sensitive to cough challenge than men. C2 and C5 were significantly lower in patients with asthma or gastroesophageal reflux than in post-nasal drip syndrome. No significant correlation was observed between the capsaicin cough threshold and PC20. Cough sensitivity did not improve significantly in most patients with asthma or gastroesophageal reflux despite adequate medical treatment during 3 months. Discriminative value of capsaicin test to differentiate healthy subjects from patients with asthma or reflux was poor. CONCLUSIONS Cough sensitivity to inhaled capsaicin is a safe and reproducible tool in the study of chronic cough. However, its usefulness for the management and differential diagnosis is limited.

Abstract
UNLABELLED Dynamic cholescintigraphy (DCG) is a valid technique for evaluating gallbladder emptying. Cholecystokinin (CCK) as a slow infusion is recommended as a contraction stimulus. The normal ejection fraction (EF) has been shown to be reproducible, although the reproducibility of abnormal results has not been investigated. The aims of the present study were to standardize the CCK administration method (phase 1), obtain EF normality values (phase 2), and evaluate the reproducibility of abnormal results in patients with clinically suspected gallbladder dysfunction (phase 3). METHODS Phase 1 included 40 healthy volunteers divided into 4 groups (n = 10) and subjected to intravenous CCK infusion according to 4 different regimens (0.25, 0.30, 0.40, and 0.60 Ivy dog units [IDU]/kg). Phase 2 comprised 33 healthy volunteers for determining DCG normality values, and phase 3 evaluated the reproducibility of abnormal results in 44 patients having clinical manifestations compatible with gallbladder dysfunction and showing an abnormal EF in a previous study. RESULTS The most effective CCK infusion regimen was 0.40 IDU/kg (3.07 ng/kg) over 20 min, because it afforded the least variability and a high EF. When this regimen was applied to the healthy population, the EF was found to be 74.2% +/- 17.1% (mean +/- SD); the inferior normality limit was estimated to be 40%. Abnormal results were recorded in 77% (95% confidence interval, 62%-89%) of the patients. When the 2 DCG studies of phase 3 were compared, the EF correlation coefficient between them was 0.439 (P = 0.003). CONCLUSION Slow CCK infusion is the best regimen for stimulating gallbladder contraction; an EF of less than 40% is estimated to represent abnormality. The abnormal results for the EF in patients with clinically suspected gallbladder dysfunction proved to be reproducible.

Abstract
BACKGROUND Disturbed bowel habit, diarrhoea or constipation is a key manifestation of irritable bowel syndrome (IBS). In some patients, diarrhoea and constipation alternate, giving rise to the so-called alternating subtype. AIMS To assess IBS subtype breakdown (constipation (C-IBS), diarrhoea (D-IBS) or alternating (A-IBS)) according to the Rome II criteria and patients' self-assessment, the predominance in the alternating subtype (i.e. constipation, diarrhoea or neither), and the medical and personal impact, including health-related quality of life (HRQoL), of the different IBS subtypes. SUBJECTS AND METHODS Two thousand individuals selected randomly to represent the general population were classified as potential IBS subjects (n = 281) or as non-potential IBS subjects (n = 1719) according to a validated questionnaire. Bowel habit classification was determined using the Rome II IBS supportive symptoms. RESULTS Among 201 subjects meeting the Rome I criteria, 15% presented with D-IBS, 44% presented with C-IBS, 19% presented with A-IBS, and 22% presented with normal bowel habit. Among the 63 subjects meeting the Rome II criteria, 23% presented with A-IBS. According to the subjects' self-assessment, of those meeting the Rome I criteria, 16% considered themselves to have D-IBS, 66% to have C-IBS and 18% to have A-IBS. In subjects meeting the Rome II criteria, 24% considered themselves to have A-IBS. Among those classified with A-IBS by the Rome II criteria, most considered themselves to be constipated. Regardless of the subtype self-classification, most subjects reported a normal frequency of bowel movements. Clinical manifestations in A-IBS were very similar to those of C-IBS but with the added presence of defecatory urgency. Abdominal discomfort/pain and frequency of visits to physicians were greater in the A-IBS subtype than in the other two IBS subtypes. HRQoL was affected similarly in all IBS subtypes. CONCLUSIONS Approximately one-quarter of subjects with IBS belong to the A-IBS subtype by the Rome II criteria, although the majority consider themselves to be constipated; indeed, clinical manifestations are more akin to the C-IBS subtype than to the D-IBS subtype. Abdominal discomfort/pain and frequency of visits to physicians are greater in the A-IBS subtype than in the other two IBS subtypes, while HRQoL is impaired similarly.

Abstract
AIMS Although the results of dynamic ultrasonography (DUS) are similar to those of dynamic cholescintigraphy (DCS) in the study of gallbladder function, the methodology required for this technique is laborious and sometimes complex. The aim of this study was to investigate the reliability of a simple method of DUS to evaluate gallbladder function using DCS as a reference. PATIENTS AND METHODS Gallbladder function was studied using DUS and DCS in 80 consecutive patients with clinical findings compatible with gallbladder dysfunction. For DUS the ellipsoid method was used with measurement of three gallbladder diameters (transversal, longitudinal and anteroposterior) in basal conditions and after applying a cholecystokinetic stimulus (meal test); gallbladder emptying of less than 50% was considered abnormal. In DCS intravenous cholecystokinin (CCK) (0.40 IDU/kg in 20 minutes) was used as stimulus and an ejection fraction < or = 40% was considered abnormal. RESULTS In 15 patients (19%; 95% CI, 11-29%) abnormal gallbladder response was found using DUS. The ejection fraction in the entire group of patients studied was 48 26.2%. Ejection fraction was abnormal in 41 patients (51%; 95% IC, 40-63%) with a value of 25 8.5% and was normal in 39 patients (49%; 95% IC, 40-63%) with a value of 71.5 14.5%. The correlation coefficient between the values of gallbladder emptying calculated with DUS and the ejection fraction obtained with DCS was 0.199 (p = 0.079). When patients were divided according to gallbladder emptying measured by DUS and the ejection fraction obtained with DCS the concordance was very low (k = 0.065; EE = 0.085). CONCLUSIONS DUS performed using a simple technique lacks diagnostic value in gallbladder dysfunction when DCS is taken as a reference test

Abstract
Presacral abscess is a rare musculoskeletal complication of Crohn's disease. The clinical picture is sometimes insidious and a delay in diagnosis may increase morbidity. Abdominal-pelvic computerized axial tomography (CAT) has proven to be very useful in the diagnosis of this entity, which usually requires surgical treatment. We present the case of a 22-year-old man who presented to hospital for colic-type abdominal pain of 6 months' evolution and intermittent episodes of joint pain. The patient also presented mechanical pain in the right gluteus muscle of two weeks' evolution irradiating to the posterior side of the muscle. Complementary investigations confirmed the suspected diagnosis of Crohn's disease and showed presacral abscess. Treatment was surgical.

Abstract
OBJECTIVE To evaluate possible changes occurring in muscle fibers related to the training status of professional road cyclists. DESIGN A comparative study was performed on two groups of male road cyclists: ten 21-yr-old cyclists with a history of 3 yr of sport competition (RC21) and ten 25-yr-old cyclists with a history of 7 yr of competition (RC25). The control group was formed by two subgroups of five nontrained, sedentary volunteers who were matched for age with the study subjects (NT21 and NT25). Biopsies of the vastus lateralis muscle were obtained to determine the fiber variables: percentage, cross-sectional area, mitochondrial volume, and capillary density. RESULTS Control group variables were within the normal range. According to their training status, cyclists showed an increased percentage of type I and IIC fibers (RC25 > RC21 > NT) and decreased percentage of type IIA (RC25 < RC21 < NT) and IIB fibers (RC25 = RC21 < NT), an increased cross-sectional area of all fiber types after 3 yr of training (RC25 = RC21 > NT) except IIB fibers (RC25 > RC21), an increased mitochondrial volume in all fiber types (RC25 > RC21 > NT) except type IIA fibers (RC25 > RC21 = NT21), and an increased capillary density (RC25 > RC21 > NT). CONCLUSIONS Findings indicate a progressive increase in the muscle fiber types that are mostly implicated in endurance sports, accompanied by phenotypic changes in the fiber population of lesser participation.

Abstract
BACKGROUND Prior to this study we obtained a simple mathematical index that uses clinical variables to predict the evolution of Crohn's disease to either a stricturing or a penetrating type. This model was based on the following variables: duration of disease before diagnosis (DD), onset of symptoms (OS), anal disease (AD) and abdominal mass (AM). The aim of our study was to validate this model in an independent cohort of patients and to investigate the relationship between some of the variables and the actual pattern of Crohn's disease in the patients. MATERIAL AND METHODS We prospectively evaluated 128 patients with Crohn's disease at the moment of diagnosis. We predicted the evolution of their disease using the mathematical model Z = -9.49 + 2.2643 (AD) - 0.0066 (DD) + 2.5282 (AM) + 1.3433 (OS). The cut-off value (reveiver operating characteristics curve) obtained in the training set of patients was P = 0.45. A value higher than this cut off discriminated patients who developed a stricturing pattern. The actual behaviour of the patients' Crohn's disease was observed after a median of 19 months from diagnosis. Of the 128 patients, 80 were classified into one of the two known patterns. Thirty-nine patients (48.8%) developed a stricturing pattern while 41 (51.2%) had a penetrating form of Crohn's disease. RESULTS The sensitivity of the model for predicting a stricturing type was 100% and the specificity was 31.7%. A P value of < 0.45 proved to be highly reliable in predicting the evolution to a penetrating pattern (positive predictive value was 100% and negative predictive value was 58%). No statistical differences were found between stricturing-type or penetrating-type groups in terms of anal disease, abdominal mass, duration of disease or onset of symptoms. Compared to patients with the penetrating form, initial ileal location was significantly more frequent than colonic location in patients with the stricturing type of Crohn's disease. CONCLUSIONS We have validated a simple mathematical model that is able to predict the behaviour of Crohn's disease in patients based on clinical variables collected at their initial evaluation. This model can be considered a useful tool for patient management. The anatomical location of the disease is related to the evolutive pattern.

Abstract
OBJECTIVES To evaluate the burden of illness in irritable bowel syndrome (IBS), in terms of resource utilisation (direct and indirect) and health-related quality of life (HR-QOL), in individuals with IBS who meet Rome I and Rome II criteria. METHODS A cross-sectional study, carried out by personal interview, on a representative sample (n = 2000) of the Spanish population. Individuals with suspected IBS were identified via a screening question and subsequently given an epidemiological questionnaire to complete. The questionnaire collected information on IBS symptoms, resource utilisation, and HR-QOL [Medical Outcomes Study 36-item Short Form (SF-36)]. RESULTS Sixty-five individuals met Rome II criteria for IBS, while 146 individuals met exclusively Rome I criteria. Of Rome II individuals, 67.7% had consulted some type of healthcare professional in the previous 12 months, compared with only 41.8% of those individuals meeting exclusively Rome I criteria (p vs 17.1%); 'drug consumption' (70.8 vs 45.2%); and 'reduced performance in main activity' (60 vs 27.4%). Compared with the general population, the study sample reported significantly worse HR-QOL scores in four dimensions of the SF-36 ('bodily pain', 'vitality', 'social functioning' and 'role-emotional'. Additionally, individuals meeting Rome II criteria reported worse HR-QOL scores than those individuals meeting exclusively Rome I criteria, especially in the 'bodily pain' and 'general health' dimensions. CONCLUSIONS The burden of illness in IBS is important and correlated to the diagnostic criteria employed. Individuals who met Rome II criteria reported a higher level of resource utilisation and worse HR-QOL than individuals meeting exclusively Rome I criteria.

Abstract
Colonic pseudo-obstruction is characterized by non-mechanical chronic colonic dilatation. It is an infrequent entity that can be provoked by multiple causes, among them pharmacological. We present the case of a 74-year-old female psychiatric patient who presented abdominal bloating, diarrhea, intense electrolytic alterations and marked radiographic colonic dilatation after treatment with a neuroleptic (zuclopenthixol decanoate). Organic obstruction and other causes were ruled out and the final diagnosis was chronic colonic pseudo-obstruction secondary to the use of neuroleptics. Cisapride (20 mg/8 h) produced a slight improvement in symptoms but colonic dilatation was permanent.
