Abstract
Chronic pancreatitis (CP) is a complex disease with a wide range of clinical manifestations. This range comprises from asymptomatic patients to patients with disabling symptoms or complications. The management of CP is frequently different between geographic areas and even medical centers. This is due to the paucity of high quality studies and clinical practice guidelines regarding its diagnosis and treatment. The aim of the Spanish Pancreatic Club was to give current evidence-based recommendations for the management of CP. Two coordinators chose a multidisciplinary panel of 24 experts on this disease. These experts were selected according to clinical and research experience in CP. A list of questions was made and two experts reviewed each question. A draft was later produced and discussed with the entire panel of experts in a face-to-face meeting. The level of evidence was based on the ratings given by the Oxford Centre for Evidence-Based Medicine. In the second part of the consensus, recommendations were given regarding the management of pain, pseudocysts, duodenal and biliary stenosis, pancreatic fistula and ascites, left portal hypertension, diabetes mellitus, exocrine pancreatic insufficiency, and nutritional support in CP.

Abstract
Chronic pancreatitis (CP) is a relatively uncommon, complex and heterogeneous disease. The absence of a gold standard applicable to the initial phases of CP makes its early diagnosis difficult. Some of its complications, particularly chronic pain, can be difficult to manage. There is much variability in the diagnosis and treatment of CP and its complications amongst centers and professionals. The Spanish Pancreatic Club has developed a consensus on the management of CP. Two coordinators chose a multidisciplinary panel of 24 experts on this disease. A list of questions was drafted, and two experts reviewed each question. Then, a draft was produced and shared with the entire panel of experts and discussed in a face-to-face meeting. This first part of the consensus addresses the diagnosis of CP and its complications.

Abstract
BACKGROUND AND AIMS Knowledge on the aetiology of exocrine pancreatic cancer (EPC) is scant. The best established risk factor for EPC is tobacco smoking. Among other carcinogens, tobacco contains cadmium, a metal previously associated with an increased risk of EPC. This study evaluated the association between concentrations of trace elements in toenails and EPC risk. METHODS The study included 118 EPC cases and 399 hospital controls from eastern Spain. Levels of 12 trace elements were determined in toenail samples by inductively coupled plasma mass spectrometry. OR and 95% CI, adjusted for potential confounders, were calculated using logistic regression. RESULTS Significantly increased risks of EPC were observed among subjects whose concentrations of cadmium (OR 3.58, 95% CI 1.86 to 6.88; p(trend)=5×10(-6)), arsenic (OR 2.02, 95% CI 1.08 to 3.78; p(trend)=0.009) and lead (OR 6.26, 95% CI 2.71 to 14.47; p(trend)=3×10(-5)) were in the highest quartile. High concentrations of selenium (OR 0.05, 95% CI 0.02 to 0.15; p(trend)=8×10(-11)) and nickel (OR 0.27, 95% CI 0.12 to 0.59; p(trend)=2×10(-4)) were inversely associated with the risk of EPC. CONCLUSION Novel associations are reported of lead, nickel and selenium toenail concentrations with pancreas cancer risk. Furthermore, the results confirm previous associations with cadmium and arsenic. These novel findings, if replicated in independent studies, would point to an important role of trace elements in pancreatic carcinogenesis.

Abstract
We analyzed relationships of hepatic and pancreatic biomarkers with the cholestatic syndrome and tumor stage in exocrine pancreatic cancer (N = 183). Information on laboratory tests and on signs and symptoms was obtained from medical records and patient interviews. Bilirubin, aspartate aminotransferase (AST), γ-glutamyltransferase (GGT) and alkaline phosphatase were lower in tumor stage IV. The association was due to the relationship between cholestatic syndrome and earlier presentation of patients. There was no association between hepatic biomarkers and stage when adjusting by cholestatic syndrome. Relationships of hepatic and pancreatic biomarkers with pancreatic symptoms and tumor stage must be controlled in "-omics" and other studies using biomarkers.

Abstract
CASE REPORT we describe the case of a 46-year-old patient with cystic dystrophy of the pancreas admitted for alcoholic pancreatitis in a state of alcohol deprivation. The patient's background includes two cases of acute pancreatitis and a computed tomography taken 18 months prior to admittance reveals a 9 mm cyst in the first duodenal portion. Magnetic resonance imaging and endoscopic ultrasonography were consistent with cystic dystrophy of the pancreas without stenosis, for which reason treatment with octreotide was initiated. DISCUSSION it is believed to be a disease caused by obstruction of the ducts of the heterotopic pancreas and is associated with alcoholic pancreatitis. Its treatment is still under debate, but it requires pancreatectomy as a last option. CONCLUSION cystic dystrophy of the pancreas is a rare disease and an effort should be made to bring together all of the described cases to increase our understanding of the disease.

Abstract
The diagnostic utility of detecting K-ras mutations for the diagnosis of exocrine pancreatic cancer (EPC) has not been properly studied, and few reports have analysed a clinically relevant spectrum of patients. The objective was to evaluate the clinical validity of detecting K-ras mutations in the diagnosis of EPC in a large sample of clinically relevant patients. We prospectively identified 374 patients in whom one of the following diagnoses was suspected at hospital admission: EPC, chronic pancreatitis, pancreatic cysts, and cancer of the extrahepatic biliary system. Mutations in the K-ras oncogene were analysed by PCR and artificial RFLP in 212 patients. The sensitivity and specificity of the K-ras mutational status for the diagnosis of EPC were 77.7% (95% CI: 69.2-84.8) and 78.0% (68.1-86.0), respectively. The diagnostic accuracy was hardly modified by sex and age. In patients with either mutated K-ras or CEA > 5 ng/ml, the sensitivity and specificity were 81.0% (72.9-87.6) and 62.6% (72.9-87.6), respectively. In patients with mutated K-ras and CEA > 5 ng/ml the sensitivity was markedly reduced. In comparisons with a variety of non-EPC patient groups sensitivity and specificity were both always greater than 75%. In this clinically relevant sample of patients the sensitivity and specificity of K-ras mutations were not sufficiently high for independent diagnostic use. However, it seems premature to rule out the utility of K-ras analysis in conjunction with other genetic and 'omics' technologies.

Abstract
BACKGROUND In pancreatic ductal adenocarcinoma (PDA), evidence on the etiopathogenic role of alcohol consumption in the occurrence of K-ras mutations is scant, and the role of alcohol in pancreatic carcinogenesis is not well established. We analyzed the relation between lifetime consumption of alcohol and mutations in codon 12 of the K-ras oncogene in patients with PDA. METHODS Incident cases of PDA were prospectively identified and interviewed face-to-face during hospital admission about lifetime alcohol consumption and other lifestyle factors. Logistic regression was used to compare PDA cases (N = 107) with mutated and wild-type K-ras tumors (case-case study). RESULTS Mutated cases were moderate or heavy drinkers more frequently than wild-type cases: the odds ratio adjusted by age, sex, smoking, and history of pancreatitis (ORa) was 3.18 (95% confidence interval: 1.02-9.93; P = 0.046). Total grams of alcohol and years of consumption were higher in mutated than in wild-type cases: the ORa for lifetime alcohol consumption over 507,499 g was 3.35 (95% CI: 0.81-13.88); and for more than 40 years of alcohol consumption it was 4.47 (95% CI: 1.05-19.02). Age at onset of alcohol consumption and years of abstinence were also associated with the presence of K-ras mutations. There were no significant differences in alcohol dependency. CONCLUSIONS Alcohol consumption is weakly associated with an increased risk of having a K-ras mutated PDA. To confirm or to refute the hypothesis that ethanol, acetaldehyde or other alcohol-related substances might influence the acquisition or persistence of K-ras mutations in the pancreatic epithelium, large and unselected studies are warranted.

Abstract
Abdominal pain is the most frequent symptom in patients with chronic pancreatitis. Between 70 and 90% of patients experience pain at some point in the course of their disease. In patients with alcoholic pancreatitis, pain is usually experienced at disease onset. Two distinct forms of idiopathic chronic pancreatitis can be distinguished: in early-onset (juvenile) idiopathic chronic pancreatitis, pain occurs initially, while in late-onset (senile) idiopathic chronic pancreatitis, pain is delayed or may even be absent. According to several authors, between 27 and 67% of patients require surgery due to lack of response to medical treatment. Pain may reoccur in more than 30% of patients who have undergone surgery and consequently, reintervention is not uncommon. Several treatment options are currently available: medical, endoscopic and surgical. The most appropriate treatment for each patient should be chosen on an individualized basis.

Abstract
OBJECTIVES We analyzed the relation between mutations in codon 12 of the K-ras oncogene and lifetime consumption of tobacco in patients with exocrine pancreatic cancer (EPC). METHODS Incident cases of EPC were prospectively identified and interviewed during hospital admission about smoking and other factors. Exact logistic regression was used to compare EPC cases (N = 107) with and without K-ras mutations (case-case study). RESULTS Mutated cases were nonsignificantly less likely to have been smokers than wild-type cases: the odds ratio adjusted by age and sex was 0.54 (95% confidence interval, 0.10-2.69; P = 0.613). With respect to never smokers, adjusted odds ratios for former and current smokers were 0.79 and 0.36, respectively (P = 0.193). Pack-years smoked, years of smoking, and cigarettes smoked per year also tended to be higher in nonmutated than in mutated cases. Neither age at onset of smoking nor the time between quitting and diagnosis were associated with K-ras. CONCLUSIONS Tobacco does not play a major part in the acquisition of K-ras mutations in the pancreatic epithelium. Although both smoking and K-ras mutations have important roles in the etiopathogenesis of EPC, the 2 processes may act independently.

Abstract
BACKGROUND No studies have investigated the relation between K-ras mutations and dietary factors in exocrine pancreatic cancer (EPC), and fewer than 10 studies have done so in other neoplasms. PATIENTS AND METHODS Incident cases of EPC were prospectively identified, and interviewed face-to-face during hospital admission. Food and nutrient intakes were measured with a food frequency questionnaire. Logistic regression was used to compare EPC cases (n = 107) with and without K-ras mutations (case-case study). RESULTS K-ras mutations were more common among daily consumers of milk and other dairy products than among non-daily consumers: the odds ratio adjusted by total energy, age, sex, smoking, alcohol and coffee consumption (ORa) was 5.1 (95% CI 1.1 to 24.5, p = 0.040). For all dairy products, including butter, the ORa for the medium and upper tertiles of intake were 5.4 and 11.6, respectively (p for trend = 0.023). The ORa for regular coffee drinkers further adjusted by dairy consumption was 4.7 (95% CI 1.1 to 20.7, p = 0.043). K-ras mutated cases reported a lower intake of vitamin E (ORa = 0.2, p for trend = 0.036), polyunsaturated fats and omega 3 fatty acids (ORa = 0.2; p for trend <0.03). CONCLUSIONS Results support the hypothesis that in EPC exposure to specific dietary components or contaminants may influence the occurrence or persistence of K-ras mutations.

Abstract
BACKGROUND Malabsorption syndrome often develops in patients with common variable immunodeficiency (CVID). Why structural damages appear in some CVID patients and not in others is not fully understood. Memory B cells (MBs) are responsible for the production of specific antibodies, and their defects have previously been related to autoimmune, granulomatous, and lymphoproliferative complications of CVID. The objective of this study was to ascertain whether a relationship exists between MB defects and the clinical outcome of respiratory and intestinal involvement in these patients. METHODS Forty-one CVID patients were grouped as follows, according to the quantification of peripheral MBs: the MB2 group (n = 7) included patients with normal MBs; the MB1 group (n = 16) included patients with low switched MBs; and the MB0 group (n = 18) included patients with absent/low MBs. The clinical outcome of respiratory and intestinal involvement of patients was then compared among the three groups. RESULTS In the MB0 group, chronic lung disease (ie, bronchiectasis and diminished FVC and/or FEV1) developed in 50% of patients vs 13% in the MB1 group and 0% in the MB2 group (p < 0.05). In the MB0 group, malabsorption syndrome or chronic noninfectious diarrhea developed in 50% of patients vs 19% in the MB1 group and 0% in the MB2 group (p < 0.05). No differences were found among the three groups for age at onset of symptoms, delay in diagnosis/treatment, months of follow-up/treatment, and prediagnostic serum IgG concentration. CONCLUSIONS Alterations in MB count appear to be associated with a severe clinical outcome of respiratory and intestinal involvement in CVID. The MB count could be a useful laboratory parameter for orienting the prognosis and management of CVID patients.

Abstract
Pancreatic pseudocyst is a common complication of acute and chronic pancreatitis. Extrapancreatic locations of pancreatic pseudocyst in the liver, pleura, mediastinum, or pelvis have been described. However, a pancreatic pseudocyst located in the liver is an infrequent condition. We present the case of a 46-year-old man with pancreatic pseudocyst located in the liver secondary to chronic alcoholic pancreatitis. During admission, the patient underwent an abdominal CT scan that showed a mass located in the head and body of the pancreas, as well as a thrombosis of the splenic vein. A percutaneous needle aspiration biopsy of the pancreas was obtained under CT guidance, which showed no tumoral involvement. Fourty-eight hours after the procedure the patient developed abdominal pain and elevated serum amylase levels. A pancreatic MRI exam showed two pancreatic pseudocysts, one of them located in the left hepatic lobe, the other in the pancreatic tail. Chronic pancreatitis signs also were found. Enteral nutrition via a nasojejunal tube was administered for two weeks. The disappearance of the pancreatic pseudocyst located in the pancreatic tail, and a subtotal resolution of the pancreatic pseudocyst located in the liver were observed. To date twenty-seven cases of pancreatic pseudocyst located in the liver have been published, most of them managed with percutaneous or surgical drainage.

Abstract
INTRODUCTION The need to detect pancreatic cancer at earlier stages is undisputed. We recorded the signs and symptoms of patients presenting with exocrine pancreatic cancer and evaluated their association with clinical characteristics such as tumour site and disease stage. PATIENTS AND METHODS All patients (n = 185) with exocrine pancreatic cancer newly diagnosed at five general hospitals in Eastern Spain were prospectively recruited over 5 years. Symptoms were elicited through personal interviews and signs were recorded by the attending physician on admission. RESULTS At diagnosis, one third of tumours of the pancreas head were in stage I and another third in stage IV. None of the tumours of the body and tail were in stage I, and over 80% were in stage IV (p < 0.001) . At presentation, the most frequent symptoms were asthenia (86%), anorexia (85%), weight-loss (85%), abdominal pain (79%), and choluria (59%). Cholestatic symptoms were more common in tumours affecting only the pancreatic head (p < 0.001) . There was a clear trend toward more localized tumours with increasing numbers of cholestatic signs (p < 0.001) . Asthenia, anorexia and weight-loss were unrelated to stage. An increased symptom-to-diagnosis interval was associated with more advanced stage (p = 0.048). CONCLUSIONS Proper attention to signs and symptoms, especially cholestasis, may help identify patients with pancreatic cancer at an earlier stage. Results also provide a current picture of the semiology of pancreatic cancer which could be of use in studies on the potential of proteomic tests in the early detection of this neoplasm.

Abstract
BACKGROUND Since the CFTR gene was cloned, more than 1000 mutations have been identified. To date, a clear relationship has not been established between genotype and the progression of lung damage. A study was undertaken of the relationship between genotype, progression of lung disease, and survival in adult patients with cystic fibrosis (CF). METHODS A prospective cohort of adult patients with CF and two CFTR mutations followed up in an adult cystic fibrosis unit was analysed. Patients were classified according to functional effects of classes of CFTR mutations and were grouped based on the CFTR molecular position on the epithelial cell surface (I-II/I-II, I-II/III-V). Spirometric values, progression of lung disease, probability of survival, and clinical characteristics were analysed between groups. RESULTS Seventy four patients were included in the study. Patients with genotype I-II/I-II had significantly lower current spirometric values (p < 0.001), greater loss of pulmonary function (p < 0.04), a higher proportion of end-stage lung disease (p < 0.001), a higher risk of suffering from moderate to severe lung disease (odds ratio 7.12 (95% CI 1.3 to 40.5)) and a lower probability of survival than patients with genotype I-II/III, I-II/IV and I-II/V (p < 0.001). CONCLUSIONS The presence of class I or II mutations on both chromosomes is associated with worse respiratory disease and a lower probability of survival.

Abstract
OBJECTIVES The hydrogen (H2) breath test is widely used in the assessment of carbohydrate malabsorption. Severe exocrine pancreatic insufficiency markedly diminishes pancreatic amylase production and results in malabsorption of complex carbohydrates. Thus, the H2 breath test with low-dose rice flour starch was tested to determine its value in detecting exocrine pancreatic insufficiency by comparison with a direct measurement of pancreatic function. METHODS Ten patients with clinically suspected pancreatic insufficiency confirmed with a duodenal perfusion technique and measurement of trypsin and lipase output after cerulein stimulation were included. An H2-rice flour breath test was performed by orally administering 30 g of rice flour. End-alveolar breath samples were obtained before rice load and at 30-minute intervals thereafter for the next 5 hours. RESULTS The results are expressed as median (percentile 25-75). Patients included 8 men and 2 women with moderate to severe exocrine pancreatic insufficiency due to chronic pancreatitis, pancreatectomy, or cystic fibrosis. Stimulated duodenal output of lipase and trypsin was abnormally low in all patients (median release, 1.7; range, 0.5-4.5 and 0.8, range, 0.1-11.3 KU/h, respectively). Basal H2 excretion was 9 ppm (range, 7-17) and delta increase over basal H2 excretion was 4 ppm (range, 1-6). Correlation between H2-rice breath test and basal or stimulated duodenal output of lipase and trypsin was not significant. CONCLUSION In exocrine pancreatic insufficiency, an oral load of 30 g rice flour slightly raises H2 excretion in breath. This increase is not useful for detecting pancreatic insufficiency due to poor sensitivity and because it is influenced by extrapancreatic factors such as small bowel bacterial overgrowth.

Abstract
BACKGROUND Our goal was to establish the clinical and genetic characteristics of patients diagnosed with adult-onset cystic fibrosis (CF). PATIENTS AND METHOD This was a retrospective observational descriptive comparative study of CF patients according to their age at the time of diagnosis. All adult patients (> 16 years old) attended in our CF Unit until November 2001 were included in the study. Those patients diagnosed of CF at their childhood (< 16 years old) were categorized as Group A patients, and those diagnosed in adulthood (>= 16 years old) were categorized as group B patients. Anthropometric parameters, respiratory and digestive clinical abnormalities, chest and abdominal radiological exams, sputum bacteriology, respiratory function and genetic tests were evaluated. Statistical analysis between groups was performed by comparing chi square test for qualitative values and the Student t test for quantitative values. RESULTS One hundred and eleven patients (60 women, mean age 28, range 16-69 years) out of a total sample of 245 (45.3%) patients attended at the CF unit were enrolled in the study. Group A included 61 patients (32 women; mean age 23) and group B included 50 patients (28 women; mean age 32). The comparative study between both groups showed that patients in group B were older, had a higher weight and less incidence of initial digestive abnormalities, pancreatic insufficiency, malnutrition, hepatic disease, chronic bronchial colonization by Pseudomonas aeruginosa, admissions, lung transplantation and deaths due to CF. On the contrary, these patients had a higher incidence of pancreatitis, allergic bronchopulmonary aspergillosis at diagnosis and better respiratory function test parameters. The sweat test was negative in 4 patients of group B and 1 of group A. The genetic study showed 31 different CF mutations, from which only 10 were observed in group B. CONCLUSIONS CF can also be diagnosed in adult age. Patients diagnosed in adulthood have less digestive abnormalities, better lung function and different genetic mutations. The sweat test can be negative or undetermined. These patients also display a better prognosis.

Abstract
Clinical, biochemical, and genetic features of a Spanish family with mitochondrial neurogastrointestinal encephalomyopathy are reported. The proband presented with severe gastrointestinal dysmotility and the affected sister had extraocular muscle weakness. In both affected individuals, biochemical defects of thymidine phosphorylase and a pathogenic G-to-A transition mutation at nucleotide 435 in the thymidine phosphorylase gene were identified. The first thymidine phosphorylase mutation identified in Spain showed phenotypic variability at onset.

Abstract
Cystic fibrosis is a hereditary disease well known to paediatricians. Over recent years, its prevalence among the adult population has dramatically increased; thus becoming a disease increasingly seen in adult practice. Cystic fibrosis is a multi-organ disease, with a wide spectrum of clinical manifestations involving many organs. The aim of this article is to review the digestive system manifestations of this disease: the involvement of the gastrointestinal tract, liver, biliary system and pancreas, with a special emphasis on the adult population.

Abstract
BACKGROUND/AIMS Both total parenteral nutrition and long-term octreotide treatment (> 2 months) may induce biliary sludge and lithiasis. However, the lithogenic capacity of the combination of the two treatments in the short-term is unknown. This study was undertaken to evaluate the lithogenic capacity of short-term octreotide treatment (< 1 month) in patients with acute pancreatitis who are also receiving total parenteral nutrition, and to determine the evolution of patients who develop biliary sludge and/or lithiasis. METHODOLOGY Thirty patients with acute pancreatitis were studied (21 males, 9 females; average age: 38). All patients received total parenteral nutrition and analgesics. In a double-blind random manner, 15 patients were treated with a continuous subcutaneous administration of octreotide (200 micrograms/8 h) and a further 15 patients received placebo. Biliary sludge and/or lithiasis were examined by ultrasonography. An echographic examination of the gallbladder was performed every seven days while the patients were in hospital. They were followed up every month, when another ultrasound of the gallbladder was carried out. RESULTS Sixteen patients (53%) developed sludge: ten (67%) from the octreotide group and six (33%) from the placebo group (P = 0.29). Two of the patients from the octreotide group had microlithiasis (P = 0.34) and a cholecystectomy was required. In the other 14 patients, sludge had disappeared by the time of the check-up performed one month after discharge. CONCLUSIONS Short-term octreotide treatment does not increase the risk of developing biliary sludge and/or lithiasis in patients also receiving total parenteral nutrition. Biliary sludge formed during total parenteral nutrition and short-term octreotide therapy may disappear when patients begin oral intake. Therefore, preventive measures are not required.

Abstract
BACKGROUND The clinical prevalence of cystic fibrosis (CF) in adults continues to rise, with a consequent impact on adult gastroenterology practice. AIM To characterize the gastrointestinal manifestations of CF in adult patients. PATIENTS AND METHODS The clinical records of 89 adult CF patients treated at our institution from 1992 to 1999 were reviewed. Patients were distributed into two groups: group A (39 patients), which consisted of patients who were diagnosed with CF at when they were younger than 14 years old and who survived into adulthood; and group B (50 patients), who were diagnosed with CF at the age of 14 years or older. Data on CF genetic mutations, nutritional state, evidence of pulmonary, gastrointestinal, liver, or pancreatic involvement were collected for each patient. RESULTS The most prevalent genetic mutation in our series was deltaF508, present in 50 patients (56.2%), 29 of whom belonged to group A and 21 who belonged to group B. In group A, the deltaF508 mutation was associated with exocrine pancreatic insufficiency (PI) in 26 of 29 patients (89.6%), whereas in group B it was associated with PI in only four patients (19%). Overall, PI was present in 33 of 39 patients (84.6%) in group A and in eight of 50 patients (16%) in group B. Four patients in group B had experienced previous episodes of acute pancreatitis; two of them had associated PI. Of the 89 patients, 12 (10 in group A) were malnourished. Malnutrition was invariably associated with PI. Hepatic and biliary tree abnormalities were particularly prevalent in patients in group A and was usually associated with PI. Intestinal manifestations were uncommon. CONCLUSIONS Diagnosis of CF before the age of 14 years is associated with greater gastrointestinal compromise than diagnosis at an older age, particularly with regard to PI. CF carriers of the deltaF508 mutation have an increased risk of developing gastrointestinal manifestations.

Abstract
BACKGROUND An increased risk of chronic pancreatitis has been described among carriers of the cystic fibrosis transmembrane regulator (CFTR) mutation. In addition, patients with cystic fibrosis may have a higher risk of exocrine pancreatic cancer. AIMS To determine the prevalence of the DeltaF508 mutation and 5T allele, the most common CFTR disease related variants, and to assess their association with lifestyle factors in an unselected series of patients with chronic pancreatitis or pancreatic cancer. SUBJECTS Patients recruited to the multicentre PANKRAS II study with a diagnosis of chronic pancreatitis and pancreatic cancer from whom normal DNA was available. METHODS The DeltaF508 mutation and 5T allele were analysed using polymerase chain reaction amplified normal DNA. Information on clinical and lifestyle factors was obtained through personal interviews. RESULTS Among patients with pancreatitis, no DeltaF508 alleles were found and the prevalence of the 5T allele was 10.5%, similar to that described in the general population. Among patients with pancreatic cancer, the prevalence of the DeltaF508 mutation and the 5T allele was 2.4% and 5.5%, respectively. 5T allele carriers with cancer consumed significantly less alcohol than non-carriers (p=0.038). CONCLUSIONS Our findings do not support the view that the DeltaF508 mutation and 5T allele confer a higher risk of chronic pancreatitis or pancreatic cancer. Nevertheless, our data suggest that interactions between CFTR polymorphism and environmental factors may play a role in the pathogenesis of these diseases. Our study emphasises the need for a multinational study to conclusively establish the role of CFTR variants as genetic susceptibility factors for chronic pancreatitis and pancreatic cancer.

Abstract
BACKGROUND Occupational exposures may increase the risk of exocrine pancreatic cancer. This study aimed to identify occupations that in Spain may be associated with such risk. METHODS Incident cases of pancreatic cancer and hospital controls were prospectively identified and interviewed during their hospital stay. Occupational history was obtained by direct interview with the patient and was available for 164 (89%) of 185 pancreatic cancer cases and for 238 (90%) of 264 controls. Occupations were coded according to the Spanish version of the International Standard Classification of Occupations 1988. RESULTS A significant increased odds ratio (OR) was observed in men for 'physical, chemistry and engineering science technicians'. Elevated risks were also found for 'metal moulders, sheet-metal workers, structural metal workers, welders and related workers', 'painters and varnishers' and 'machinery mechanics and fitters'. 'Agricultural workers' did not present an increased risk for pancreas cancer in men. In women, however, high OR were observed for 'agricultural workers' and for 'textile and garment workers'. Most associations remained unchanged after considering long duration of the exposure and the period 5-15 years before diagnosis. CONCLUSIONS Few occupations were at increased risk for pancreatic cancer, and the associations observed are in accordance with previous studies. The increases in risk observed for women in agricultural and textile jobs, and for men in the manufacture of dyes and pigments may deserve further attention.

Abstract
Achalasia presenting as acute airway obstruction is an uncommon complication. We report the case of an elderly woman with previously undiagnosed achalasia who presented with acute respiratory distress due to megaesophagus. Emergency endotracheal intubation and insertion of a catheter into the esophagus, with continuous aspiration was required. Upon introduction of the esophageal catheter an abruptand audible air decompression occurred, with marked improvement of the clinical picture. Endoscopic injection of botulinum toxin was chosen as the definitive treatment with good clinical result. The pathophysiology of the phenomenon of esophageal blowing in achalasia is unclear, but different hypothetical mechanisms have been suggested. One postulated mechanism is an increase in upper esophageal sphincter (UES) residual pressure or abnormal UES relaxation with swallowing in achalasia patients. We reviewed the UES manometric findings in 50 achalasia patients and compared it with measurement performed in 45 healthy controls. We did not find any abnormalities in UES function in any of our achalasia patients group, or in the case under study. An alternative hypothesis postulates that airway compromise in patients with achalasia results from the loss UES belch reflex (abnormal UES relaxation during esophageal air distension), and in fact, an abnormal UES belch reflex was evidenced in our case.

Abstract
BACKGROUND The aim was to analyse the magnitude, direction and predictors of change in the main hospital discharge diagnosis (HDD) after a clinical expert review, among patients included in a multicentre molecular epidemiologic study of biliopancreatic diseases. METHODS A total of 602 patients with a suspicion diagnosis of pancreas cancer (PC), cancer of the extrahepatic biliary system (CEBS) or benign biliopancreatic pathologies (BPP) were prospectively recruited at five general hospitals. A structured form was used to collect information from medical records. A panel of experts revised all diagnostic information and established the main clinicopathological diagnosis (CPD) by consensus. RESULTS Of the 204 cases with a HDD of PC, 176 (86%) were deemed to have a CPD of PC, eight of CEBS, twelve a neoplasm of different origin, four BPP and four syndromic diagnoses. Thus, 28 cases (14%) were false positives. Of the 129 patients with a HDD of CEBS, 15 (12%) were false positives. Nine of the 396 cases with a HDD of non-PC (2%) had a CPD of PC (false negatives), whilst 14 of 471 patients with a HDD of non-CEBS (3%) were deemed to have CEBS. Overall, sensitivity and specificity of HDD for PC were, respectively, 95 and 93%, and for CEBS, 89 and 97%. Cytohistological confirmation and laparotomy were independent predictors of diagnostic change. CONCLUSIONS Validity of the HDD was high, but its association with some clinical variables suggests that sole reliance on HDD can significantly bias results, and highlights the need to review all HDDs. Alternatively, only patients at high risk of misdiagnosis could be reviewed: primarily, those lacking a cytohistological diagnosis or a laparotomy. No exclusions appear warranted solely on the basis of age, gender or tumour spread.

Abstract
Pancreatic cystadenocarcinoma is an uncommon neoplasm of the pancreas. Mucinous cystadenocarcinoma is the most frequent pancreatic cystadenocarcinoma. Symptoms are often non-specific but abdominal pain and jaundice are common in tumors localized in the head of the pancreas. Thromboembolic manifestations of pancreatic neoplasm have been described but are infrequent. The commonest manifestations are migratory thrombophlebitis, mesenteric venous thrombosis and pulmonary embolism. Cerebral stroke as the first manifestation of pancreatic carcinoma is exceptional. The mechanism by which pancreatic carcinoma induces stroke is unclear, although Trousseau's syndrome, complications of mucinous cancer or blood disorders could play a role. We report the case of a young woman with transient stroke and paraneoplastic thrombocytosis in whom pancreatic cystadenocarcinoma was diagnosed.

Abstract
OBJECTIVE inflammatory bowel disease (IBD), total parenteral nutrition (TPN) and immunosuppressive treatment with cyclosporin A (CsA) are well known factors in hepatobiliary disorders. Their association, however, has been little studied. METHOD we retrospectively analyzed the results of liver function tests (transaminases, AST. ALT), total bilirubin, alkaline phosphatase, and gamma-glutamyltransferase (GGT) in a consecutive series of 50 patients (29 men, 21 women, mean age 32 years, range 16-78 years) hospitalized for a severe attack of IBD between January 1992 and July 1997. Basal laboratory values in all patients were normal. Thirty-eight patients had ulcerative colitis (UC) and 12 had Crohn's disease (CD), which debuted in 28% of the patients. All patients were treated with methylprednisolone (MP) (0.75-1.0 mg/kg daily i.v., and received TPN. 42% (21/50) required additional treatment with CsA (5 mg/kg daily i.v.) at the beginning or during the first week of TPN and during 7-24 days, because on nonresponse to steroid treatment. Two study groups were defined according to treatment: Group I consisted of 29 patients given MP + TPN, and group II comprised 21 patients who received MP + TPN + CsA. The groups were otherwise similar in all other variables analyzed. Liver function tests were done weekly until the end of the study period. RESULTS 62% of the patients (31/50) showed hepatobiliary dysfunction, defined previously as a 2-fold or greater elevation of two or more parameters. There was no statistically significant difference between the two groups in the incidence of dysfunction (15/29 vs 16/21, n.s.). The parameters that showed the greatest alterations were GGT and ALT; the greatest elevation appeared during the third week of immunosuppressive treatment, and did not exceed 6-fold the normal value. The alterations disappeared once TPN and immunosuppressive treatment were discontinued. CONCLUSIONS the hepatobiliary dysfunction in patients treated with both TPN and CsA was no more severe than associated with TPN alone.

Abstract
BACKGROUND Organochlorine compounds such as 1,1,1-trichloro-2,2-bis(p-chlorophenyl)-ethane (p,p'-DDT), 1,1-dichloro-2,2-bis(p-chlorophenyl) ethylene (p,p'-DDE), and some polychlorinated biphenyls (PCBs) are carcinogenic to animals and possibly also to human beings. Occupational exposure to DDT may increase the risk of pancreas cancer. The high frequency of K-ras mutations in pancreatic cancer remains unexplained. We analysed the relation between serum concentrations of selected organochlorine compounds and mutations in codon 12 of the K-ras gene in patients with exocrine pancreatic cancer. METHODS Cases were prospectively identified in five hospitals. Mutations in K-ras were analysed by PCR and artificial restriction fragment length polymorphism. Cases of pancreatic cancer with wild-type K-ras (n=17) were frequency matched for age and sex to cases of pancreatic cancer with a K-ras mutation (n=34, case-case study). These 51 cases were further compared with 26 hospital controls (case-control comparison). Serum organochlorine concentrations were measured by high-resolution gas chromatography with electron-capture detection and negative ion chemical ionisation mass spectrometry. FINDINGS Serum concentrations of p,p'-DDT were significantly higher in pancreatic cancer cases with a K-ras mutation than in cases without a mutation (odds ratio for upper tertile 8.7 [95% CI 1.6-48.5], p for trend=0.005). For p,p'-DDE the corresponding figures were 5.3 (1.1-25.2, p for trend=0.031). These estimates held after adjusting for total lipids, other covariates, and total PCBs. A specific association was observed between a glycine to valine substitution at codon 12 and both p,p'-DDT and p,p'-DDE concentrations (odds ratio 15.9, p=0.044 and odds ratio 24.1, p=0.028; respectively). A similar pattern was shown for the major di-ortho-chlorinated PCBs (congeners 138, 153, and 180), even after adjustment for p,p'-DDE, but without a specific association with spectrum. Concentrations of p,p'-DDT and p,p'-DDE were similar among wild-type cases and controls, but significantly higher for K-ras mutated cases than for controls (p<0.01). INTERPRETATION Organochlorine compounds such as p,p'-DDT, p,p'-DDE, and some PCBs could play a part in the pathogenesis of exocrine pancreatic cancer through modulation of K-ras activation. The results require replication, but they suggest new roles for organochlorines in the development of several cancers in human beings.

Abstract
The aims of the study were to assess the agreement between data from personal interviews and medical records on selected medical conditions, to evaluate the validity of each source of information, and to estimate the prevalence of these conditions in pancreatobiliary pathology. Between 1992 and 1995, 602 patients with pancreatobiliary diseases were included in the PANKRAS II Study. Information from interview and medical records was available in 88% of cases. The agreement between both data sources was poor only for cholecystitis and mental disorders. The validity of both sources of information was high or acceptable for all conditions except for cholecystitis. Prevalence of past medical conditions was similar to that reported previously and varied according to diagnosis, gender, age, educational level, and hospital of admission. Research aimed at assessing the prevalence of less common diseases should consider subject- and health-related factors in collecting information.

Abstract
STUDY OBJECTIVE To analyse the relation between coffee consumption and mutations in the K-ras gene in exocrine pancreatic cancer. DESIGN Case-case study. Consumption of coffee among cases with the activating mutation in the K-ras gene was compared with that of cases without the mutation. SETTING AND PATIENTS All cases of pancreatic cancer newly diagnosed at five hospitals in Spain during three years were included in the PANKRAS II Study (n = 185, of whom 121 whose tissue was available for molecular analysis are the object of the present report). Over 88% were personally interviewed in hospital. DNA was amplified from paraffin wax embedded tissues, and mutations in codon 12 of K-ras were detected by the artificial RFLP technique. MAIN RESULTS Mutations were found in tumours from 94 of 121 patients (77.7%). Mutations were more common among regular coffee drinkers than among non-regular coffee drinkers (82.0% v 55.6%, p = 0.018, n = 107). The odds ratio adjusted by age, sex, smoking and alcohol drinking was 5.41 (95% CI 1.64, 17.78). The weekly intake of coffee was significantly higher among patients with a mutated tumour (mean of 14.5 cups/week v 8.8 among patients with a wild type tumour, p < 0.05). With respect to non-regular coffee drinkers, the odds ratio of a mutated tumour adjusted by age, sex, smoking and alcohol drinking was 3.26 for drinkers of 2-7 cups/week, 5.77 for drinkers of 8-14 cups/week and 9.99 for drinkers of > or = 15 cups/week (p < 0.01, test for trend). CONCLUSIONS Pancreatic cancer cases without activating mutations in the K-ras gene had drank significantly less coffee than cases with a mutation, with a significant dose response relation: the less they drank, the less likely their tumours were to harbour a mutation. In exocrine pancreatic cancer the K-ras gene may be activated less often among non-regular coffee drinkers than among regular drinkers. Caffeine, other coffee compounds or other factors with which coffee drinking is associated may modulate K-ras activation.

Abstract
Pancreatic and biliary carcinomas remain a challenge to clinicians and investigators, as diagnosis is rarely achieved while the tumor is still in a curative stage. Clinical symptoms and signs of these neoplasias are non-specific and heterogeneous. We review the clinical presentation of these tumors, with an emphasis on their pathophysiology and relationship with survival. Abdominal pain is the most common presenting complaint in pancreatic and biliary tract carcinomas, regardless of their size; although severe back pain usually indicates neural compromise, and is associated with a short survival. Jaundice may also be an early sign, in fact, pancreatic tumors that present as painless jaundice have been ascribed, a relatively more favorable prognosis. Weight loss is a common finding in most patients, being usually associated with malabsorption. These neoplasias may also present as diabetes, as an acute pancreatitis episode, with venous thrombosis or malignant thrombophlebitis, as a gastrointestinal hemorrhage, with mental disturbances, or skin manifestations.

Abstract
Epidemiologic studies on exocrine pancreatic cancer show a large heterogeneity in diagnostic criteria applied to define "caseness." Reanalyses conducted after review of diagnostic information have yielded substantially different results than those based on more crude classifications of disease. During a multicenter prospective study on mutations in the K-ras gene in pancreatic and biliary diseases, hospital diagnoses from 602 patients were reviewed by a panel of experts. There were two main motivations to do so: a generic interest for the quality of the diagnostic data, and the anticipation that a firm diagnosis could be needed to assess whether patients whose tumors did not harbor the mutation were true negatives or false negatives. In addition, the review of diagnoses was helpful to minimize tissue misclassification, and it had a high educational value for clinicians and epidemiologists. This article illustrates why and how this was so through a brief presentation of the 10 most significant cases. With respect to selection and classification of subjects, the main issues that studies on pancreatic cancer need to address are the differential diagnosis of exocrine pancreatic cancer and pancreatitis, the differential diagnosis of exocrine pancreatic cancer and other abdominal tumors, and the use of survival as a hallmark of pancreatic cancer. In epidemiologic studies of pancreatic cancer, it is warranted that a panel of experts centrally reviews all the existing diagnostic evidence (cytohistological and other) of all patients, regardless of whether they have cytohistological confirmation and of their hospital discharge diagnosis.

Abstract
Thrombotic thrombocytopenic purpura (TTP) constitutes a poorly understood multisystemic disease of vascular origin that may involve any organ by thrombotic occlusions of the small vessels. Treatment with plasmapheresis is the best therapeutic option at this present moment. Involvement of the pancreas is a well established feature of this disease, which has generally been interpreted as a consequence of pancreatic vascular compromise. However, there are a few cases in the literature in which the clinical signs of TTP developed well after the clinical and laboratory demonstration of acute pancreatitis (AP). Therefore, the possibility of pancreatic inflammation as a triggering factor of TTP may need to be considered. This cause-effect relationship between AP and TTP remains unclear. We report a patient with chronic pancreatitis presenting with two episodes of TTP, triggered by acute relapses of pancreatitis. TTP may, thus, constitute a hematological complication of AP. We discuss the pathophysiological aspects of this association, along with therapeutical options.

Abstract
The present study was designed to investigate the prevalence of bacterial overgrowth in patients with exocrine pancreatic insufficiency by using the hydrogen breath test with glucose. Thus, in 30 patients with exocrine pancreatic insufficiency (in 15 due to chronic pancreatitis and in 15 associated to primary immunodeficiency), established by quantifying trypsin output before and after stimulation with cerulein using a duodenal perfusion technique, a glucose test was performed by administering 50 g of glucose and quantifying H2 in the breath by gas chromatography. The glucose test was positive in six of 15 patients with chronic pancreatitis but in only one of 15 immunodeficient patients (p < 0.05). Age, sex, etiology, time of evolution, associated diabetes, pancreatic calcifications, duodenal pH, or duodenal trypsin output did not differ between patients with and those without bacterial overgrowth. Previous gastroduodenal surgery was more common in chronic pancreatitis patients with overgrowth (six of six vs. four of nine; p < 0.05). Five patients with a positive glucose test were treated with antibiotics for 2 weeks and became negative in two of them. These results suggest that a positive glucose test indicating overgrowth is relatively common in exocrine pancreatic insufficiency due to chronic pancreatic, especially in patients with previous gastroduodenal surgery.

Abstract
Despite being a common disease in humans, little is known about the etiopathogenesis of and effective therapeutic approaches to chronic pancreatitis, due mainly to the fact that few simple animal models suitable to study inflammatory and fibrogenetic processes have been described in the pancreas. Trinitrobenzene sulfonic acid (TNBS) induces chronic colitis and cholangitis in the rat. We hypothesized that TNBS instillation into the pancreatic ducts could also result in the development of a chronic pancreatic disease. The biliopancreatic duct of rats was cannulated and tied close to the liver. TNBS [0.4 ml of 2% TNBS in phosphate-buffered saline (PBS)-10% ethanol, pH 8] was infused into the pancreas under a continuous controlled-pressure system. Control rats underwent the same procedure using vehicle only. Pathology assessment of TNBS-treated rats examined at 48 h was consistent with severe acute necrotizing pancreatitis, having a morality rate of 31% and serum amylase activity of 37.4 +/- 8.8 U/ml at 24 h and 13.3 +/- 1.7 U/ml at 48 h (p < 0.01 for both time points compared to PBS/ethanol-treated rats). Groups of 10 rats each were killed at 3, 4, and 6 week after the surgical procedure. Morphological examination revealed changes mimicking features of chronic pancreatitis in humans in 80% (32 of 40) of TNBS-treated rats, consisting in various degrees of periductal and lobular fibrosis, duct stenosis, patchy acute and chronic inflammatory cell infiltrates, and signs of gland atrophy. Animals developing chronic disease had a weight gain rate significantly lower than that of control rats. Serum amylase, fasting glucose, and a glucose tolerance test were not different in diseased or control rats. In conclusion, we were able to induce chronic fibrogenetic inflammatory disease in the pancreas after a single pulse instillation of TNBS into the pancreatic ducts. This might be a useful animal model to study the pathophysiology of inflammatory, fibrogenetic, and reparative processes in pancreatic tissue.

Abstract
Cystic fibrosis is the most prevalent hereditary disease in the Caucasian race. It is a multisystemic alteration that affects the quality and quantitative properties of exocrine secretions. The pancreas develops a progressive atrophy causing steatorrhoea and nutritive deficiencies. Acute pancreatitis is an unusual complication. The pancreatic atrophy prevents the inflammatory response. Published series suggest that pancreatitis in 0.5%, including patients without pancreatic insufficiency. We present two cases with cystic fibrosis, with and without pancreatic insufficiency, who developed acute pancreatitis.

Abstract
BACKGROUND The objective of this study was to determine the prevalence of thrombocytopenia in acute pancreatitis and its value as a prognostic marker for complications. METHODS The records of all patients admitted to our institution between January and June 1993 were reviewed. After exclusion of other possible causes of thrombocytopenia, 104 patients were evaluated. The prognostic value of thrombocytopenia was determined by evaluation of the length of hospital stay, radiologic severity, complications, need for ICU care, need for surgery and mortality. RESULTS The etiology of pancreatitis was as follows: gallstone-induced in 49 patients, alcoholic in 35, idiopathic in 12 and due to other causes in the remaining 8 cases. Thrombocytopenia developed early, within the first 48 hours and was moderate (106 +/- 27 x 10(9)/l). Alcoholic pancreatitis was associated to a higher probability to develop thrombocytopenia (43% vs 36% in gallstone-induced pancreatitis and 4% in idiopathic pancreatitis, p = 0.02). Thrombocytopenic patients had a greater radiologic severity (Balthazar's scores D or E 78% vs 49%, p = 0.04), a higher number of acute complications (28% vs 10%, p = 0.05) and a more frequent need for ICU care (25% vs 7%, p = 0.01). No differences were seen in length of hospital stay, need for surgery and mortality between the two groups of patients. CONCLUSIONS Thrombocytopenia is frequent in acute pancreatitis, especially in cases of alcoholic origin. Its presence suggests a higher risk to develop complications.

Abstract
The use of cyclosporine in refractory ulcerative colitis (UC) is still controversial. An 8-year-long retrospective review open-label treatment with intravenous cyclosporine in 21 patients with steroid-refractory UC is therefore in order. Intravenous cyclosporine, 5 mg/kg-1 day, was added to ongoing drug therapy. Those who responded were switched to oral cyclosporine for a mean 8.4-month period, and steroids were discontinued when possible. Sixteen out of 21 patients improved (76%). Mean latency time to onset of improvement was 9 days. Five did not improve: three underwent urgent surgery, one was switched to methotrexate, and the remainder died. While on oral cyclosporine, 10 out of 16 maintained remission and seven could discontinue steroids, five relapsed, and one went on continuous mild activity. One patient died of a Pneumocystis carinii pneumonia, while in remission. Five reversible episodes of hepatobiliary toxicity were recorded. Intravenous cyclosporine effectively and rapidly induces improvement of acute steroid-refractory flare-ups of UC and helps to prevent urgent surgery. However, major adverse events may limit its usefulness.

Abstract
BACKGROUND The indication for treatment with human gammaglobulin in patients with primary hypogammaglobulinemia is well established. Nonetheless, there are no uniform criteria with regard to dose, periodicity and route of administration. METHODS Twenty-seven patients with common variable immunodeficiency (CVI) who received i.m. or i.v. treatment with gammaglobulin were studied, evaluating the secondary effects, stable levels of IgG achieved, control of symptomatology, clinical evolution and the need for adjuvant therapies. RESULTS Intravenous administration was more effective than intramuscular administration to achieve higher total IgG serum levels (5.2 +/- 1.2 vs 3.5 +/- 1.6 g/l; p = 0.07) in a shorter period of time (2.1 +/- 1.6 months vs 6.3 +/- 2.8 months; p < 0.01) and with new few secondary effects. The dose and periodicity of the treatment was individualized in each patient on the basis of the needs of consumption and the speed of metabolism of the gammaglobulin, with patients with chronic bronchial suppuration and diarrhea being those requiring the greatest doses (p < 0.0001) and a short interdosis time interval (19.2 +/- 3.1 vs 23.6 +/- 3.6 days; p = 0.01). Treatment with human gammaglobulin allowed the control of recurrent bacterial infection; however, adjuvant treatment with respiratory physical measures and antibiotics were required in patients with chronic bronchial suppuration to avoid progressive alteration of respiratory function. CONCLUSIONS The administration of human gammaglobulin at adequate doses and frequency is effective to control infection, avoid the development of chronic bronchial disease, alteration of pulmonary function and the appearance of other complications. Intravenous route is safer and produces fewer secondary effects than intramuscular administration with the doses and period of the treatment requiring individualization for each patient.

Abstract
A multicenter study of acute necrotizing pancreatitis (ANP) classified in accordance with the Balthazar criteria (grades D and E), has been performed in 12 teaching hospitals. A total of 233 patients were reviewed, and the mortality rate was 26.6%. The most common etiology was biliary pancreatitis (45.5%). Among the complications, shock, renal insufficiency, pulmonary insufficiency and hemorrhagic gastritis were associated with a mortality rate of 51-66%. Diffuse fluid collections were associated with a higher mortality rate (26.8%) than localized fluid collections (14.5%). In 106 patients with gallstone pancreatitis, early surgery was performed in 17, and 5 patients (29.4%) died. No mortality was observed in 32 patients with delayed surgery. Sphincterotomy was performed in 13 patients, and 4 (30.7%) died. Early surgery (necrosectomy and closed peritoneal lavage) was undertaken in 75 patients, with a mortality rate of 39%. In conclusion, the morbidity and mortality rates of ANP can be improved with proper monitoring, adequate supportive care and the judicious use of surgery based on clinical and morphological findings.

Abstract
Oral pancreatic enzyme supplements, including those protected from gastric acidity by enteric coating, often achieve only partial correction of pancreatic steatorrhoea. To characterise the mechanisms involved in vivo, eight patients with steatorrhoea due to advanced pancreatic insufficiency and nine healthy controls were studied. Two sets of studies (small bowel intubation and five day faecal fat quantification) were randomly performed while patients were either on enteric coated pancreatin or equivalent placebo. A 260 cm long multilumen tube was used for double marker perfusion of two 20 cm segments located in the duodenum and in the ileum respectively. Luminal pH, flow, and trypsin and lipase activity outputs were measured at each segment for four hours postcibally. Placebo treated patients with pancreatic steatorrhoea had low enzyme outputs in the duodenal test segment and even lower outputs in the ileal segment. Pancreatin treatment significantly decreased steatorrhoea (p < 0.05) and increased luminal enzyme outputs (p < 0.05). The increase was much greater in the ileal than in the duodenal segment. Thus enteric coated pancreatin treatment abolished the normal gradient between postcibal duodenal and ileal lipase output. The results suggest that enteric coated pancreatin nearly corrects severe pancreatic steatorrhoea. The ingested lipase was utilised inefficiently, however, as luminal enzyme activity in the ileum was enhanced to a greater extent than in the duodenum, and consequently the absorptive potential of the small bowel was only partially utilised.

Abstract
The efficacy and safety of famotidine and ranitidine in the treatment of active duodenal ulcer were compared in a multicenter, randomized double-blind study. The study was carried out at 5 centers and involved a total of 143 patients with endoscopically documented active duodenal ulcer. The patients received either famotidine (1 40 mg tablet at night) or ranitidine 2 150 mg tablets at night). Endoscopic examinations were performed at 4 and 6 weeks of active treatment. Day and nocturnal pain were also monitored, and the laboratory and clinical profiles evaluated. One hundred and thirty-three patients fulfilled the evaluation criteria (66 patients in the famotidine group and 67 in the ranitidine group). Healing rates at weeks 4 or 6 of treatment showed no significant differences between the famotidine group and the ranitidine group. The healing rates were 78% at week 4 and 96% at week 6 in the famotidine group, and 76% at week 4 and 95% at week 6 in the ranitidine group. Similar results were observed in both treatment groups with regard to pain resolution, decrease in antacid intake and safety profile.

The patients received either famotidine (one tablet of 40 mg at night) or ranitidine (two tablets of 150 mg at night). Endoscopic examinations were performed at 4 and 6 weeks of active treatment. Daytime and nocturnal pain were also monitored, and the laboratory and clinical profiles evaluated. One hundred and thirty-three patients fulfilled the evaluation criteria (66 patients in the famotidine group and 67 in the ranitidine group). Healing rates at 4 or 6 weeks of treatment showed no significant differences between the famotidine and ranitidine groups. The healing rates were 80% at week 4 and 97% at week 6 in the famotidine group, and 77% at week 4 and 96% at week 6 in the ranitidine group. Similar results were observed in both treatment groups with regard to pain resolution, decrease in antacid intake and safety profile.

Abstract
Eight cases of acute gastroenteritis caused by Vibrio parahaemolyticus in humans are described; to our knowledge, they are the first such reported cases in Spain. All cases appeared between August 20th and October 15th, with a frequency of 8.3% regarding the overall adult patients with acute gastroenteritis, and 11.5% regarding the overall patients with positive stool culture for any enteropathogenic organism. The eight strains were Kanagawa positive and in three patients other enteropathogenic organisms were isolated in addition to Vibrio parahaemolyticus, i.e. Aeromonas hydrophila in two and Salmonella serovariety enteritidis in another. In all cases fish or shellfish had been ingested outside the patients' homes; except for one patient, who ate living clams in the seaside of Galicia, all patients ingested them at seaside restaurants from the Barcelona province. The clinical features of acute gastroenteritis were definite in all patients, but no patients had significant electrolyte losses or required hospital admission. Recovery was spontaneous and no antimicrobial agents were required. All strains were sensitive to tetracyclines, aminoglycosides, cefotaxime, ceftazidime and nearly always to co-trimoxazole.
