Abstract
LV5FU2 with high-dose leucovorin (LV), weekly infusional 5-fluorouracil (5FU) (AIO schedule) and raltitrexed have been demonstrated to be active agents in first-line treatment of colorectal cancer. We performed a 4-arm randomised trial to compare (1) a low-dose intravenous bolus of LV (20 mg/m2), followed by an intravenous bolus of 5FU (400 mg/m2), followed by a 22-hour continuous infusion of 5FU (600 mg/m2) on day 1 and day 2/2 weeks (ldLV5FU2 arm), (2) a weekly continuous infusion of high-dose 5FU (2.6 g/m2/week) for 6 weeks followed by a rest week (HD-FU arm) and (3) raltitrexed (Tomudex arm; 3 mg/m2/3 weeks) to standard LV5FU2. From 1997 to 2001, 294 patients were included. The 4 arms were well balanced for sex ratio, age, WHO performance status, the primary tumour site and prior adjuvant chemotherapy. Treatment was stopped due to low accrual. Two toxicity-related deaths were observed in the Tomudex arm. The treatments gave rise to different rates of grade 3-4 neutropenia (3, 4, 11 and 14% of the patients in the LV5FU2, ldLV5FU2, HD-FU and Tomudex arms, respectively, p = 0.028), leucopenia and vomiting. At least one episode of grade 3-4 toxicity was observed in 27, 25, 38 and 47% of the patients in the LV5FU2, ldLV5FU2, HD-FU and Tomudex arms, respectively (p = 0.016). An objective response was observed in 28, 21, 22 and 10% of the patients in the LV5FU2, ldLV5FU2, HD-FU and Tomudex arms, respectively (p = 0.04). Progression-free survival (PFS) of the patients in the Tomudex arm was statistically lower compared to that of patients treated with LV5FU2 or ldLV5FU2 (combined group; p = 0.013, log rank test). In conclusion, Tomudex is more toxic and yields shorter PFS than infusional 5FU. Despite the early closure of the study and the lack of power of the comparison, it seems that ldLV5FU2 could be considered as an active, easier and less expensive option for the treatment of metastatic colorectal cancer compared to classic LV5FU2 or weekly HD-FU.

Abstract
OBJECTIVES In healthy subjects, the neural correlates of visceral pain bear much similarity with the correlates of somatic pain. In patients with irritable bowel syndrome, the central nervous system is believed to play a strong modulatory or etiological role in the pathophysiology of the disease. We hypothesize that this role must be reflected in aberrations of central functional responses to noxious visceral stimulation in these patients. To verify this hypothesis, we have induced transient rectal pain in patients and assessed the functional responses of the brain by means of functional magnetic resonance imaging. METHODS Twelve right-handed patients (11 female) were examined. Functional imaging (1.5 T) was performed following a block paradigm, alternating epochs with and without noxious stimulation of the rectum. Rectal pain was induced by inflating a latex balloon. Whole-brain coverage was achieved by means of echo-planar magnetic resonance acquisition. RESULTS A strong variability of the individual responses to rectal pain was found in patients with irritable bowel syndrome. Significant activations were found in only two patients, and group analysis did not reveal significant activations. In contrast, all patients exhibited significant deactivations. Group analysis revealed significant deactivations within the right insula, the right amygdala, and the right striatum. CONCLUSIONS This study reveals aberrant functional responses to noxious rectal stimulation in patients with irritable bowel syndrome. Those results add grounds to the hypothesis that the central nervous system plays a significant role in the pathophysiology of this syndrome.

Abstract
In this prospective study 244 consecutive patients presenting with typical and chronic signs of gastroesophageal reflux were included. Conventional 24-hr esophageal pH monitoring was carried out to establish the symptom association probability, the concordance index, and the symptom sensitivity index. The symptom association probability could be calculated in 110 patients (45%). Two groups were identified: group 1 had normal duration of esophageal acid exposure; subgroup la (nonsignificant symptom association probability) included 39 patients (35.5%) and subgroup lb (significant symptom association probability) included 24 patients (21.8%); group 2 had abnormal duration of esophageal acid exposure; subgroup 2a (nonsignificant symptom association probability) included 21 patients (19.1%) and subgroup 2b (significant symptom association probability) included 26 patients (23.6%). In all, 56.6% of the patients presented typical symptoms of reflux not directly determined by one or repeated acid reflux episodes. The correlation between symptom association probability and the symptom sensitivity index allows for more accurate determination of esophageal acid sensitivity (subgroups lb and 2b).

Abstract
PURPOSE Chronic radiation proctitis, a well described complication of pelvic radiation therapy, can result in severe bleeding that is refractory to conventional treatment. Argon plasma coagulation is an effective treatment for hemorrhagic lesions of the gastrointestinal tract. The aim of this study was to assess the efficacy and safety of argon plasma coagulation in the management of severe radiation proctitis resistant to medical treatment. METHODS Eleven patients (10 males) aged between 54 and 86 years (mean +/- standard error of the mean, 73 +/- 3 years), with chronic radiation proctitis after radiotherapy for prostate (n = 9), uterine (n = 1) or rectal (n = 1) cancer were enrolled in this prospective study. Traditional therapies had failed including mainly topical steroids, 5-aminosalicylic acid and sometimes sucralfate. All patients had active bleeding from diffuse telangiectasias responsible for chronic anemia and seven of them required blood transfusions. The mean duration of the sessions was 20 minutes and one to five sessions (mean, 3.2 +/- 0.4), usually without anesthesia, were required to stop bleeding. Mean follow-up time was 19 +/- 2 (range, 7-30) months. RESULTS Rectal bleeding disappeared in nine patients and was greatly reduced in two. All the patients were free of transfusions during the mean follow-up of 19 months. The mean hemoglobin level was 7.7 +/- 2.8 g/dl at the first session and increased significantly (P = 0.003) to 11.5 +/- 2.6 g/dl after treatment. In two patients, a rectal stenosis appeared 7 and 11 months after the first session. CONCLUSION Argon plasma coagulation is a simple, inexpensive and effective treatment for severe refractory radiation proctitis with telangiectasias. Follow-up supervision is in progress to evaluate long term benefits and the risk of rectal stenosis.

Abstract
BACKGROUND Rabeprazole has been shown to be more potent and faster than other proton pump inhibitors in in vitro studies and highly effective in decreasing oesophageal acid exposure in patients with gastro-oesophageal reflux disease (GERD). AIM This study was a multicentre, double-blind, placebo-controlled, randomized, parallel-group comparison of three active treatment regimens utilizing two different proton pump inhibitors, or placebo, administered over 7 days in patients with GERD. METHODS Eighty-two patients with symptomatic GERD were given placebo, rabeprazole 10 mg b.d., rabeprazole 20 mg o.m., or omeprazole 20 mg o.m. for 7 days. Twenty-four hour oesophageal pH monitoring was performed at baseline and repeated at the conclusion of the treatment period. RESULTS At the end of study, the percentage time (mean +/- s.d.) with pH < 4 over a 24-h period was significantly decreased by the three active regimens but without significant difference between them (9.27 +/- 4.77; 2.53 +/- 4.27; 2.02 +/- 1.71 and 2.91 +/- 4.06 for placebo, rabeprazole 10 mg b.d., rabeprazole 20 mg o.m. and omeprazole 20 mg o.m., respectively). Acid exposure was normalized in 90% of patients treated with rabeprazole 10 mg b.d., 95% treated with rabeprazole 20 mg o.m., 78% treated with omeprazole 20 mg o.m., and only 9.5% of patients treated with placebo. Both rabeprazole and omeprazole were well-tolerated. CONCLUSIONS Although rabeprazole 20 mg o.m. showed greater activity numerically, this study demonstrates that rabeprazole 10 mg b.d. and 20 mg o.m. are equivalent to omeprazole 20 mg o.m. in decreasing oesophageal acid exposure.

Abstract
Loss of heterozygosity for polymorphic markers flanking the multiple endocrine neoplasia type 1 (MEN-1) gene in parathyroid and pancreatic islet tumours from subjects with MEN-1 has been well documented and has led to the hypothesis that the MEN-1 gene functions as a recessive tumour suppressor gene. We report a case of MEN-1 with duodeno-pancreatic gastrinoma, parathyroid hyperplasia, pituitary adenoma, adrenal adenoma, and lipomas, whose rare association with a malignant gastrointestinal stromal tumour (GIST) represents an undescribed combination. MEN-1 mutation in this family was shown as a frameshift (1607delA) in exon 10. To assess the role of the MEN-1 gene in the pathogenesis of tumours less commonly associated with MEN-1, we studied GIST DNA for loss of the unaffected MEN-1 gene allele. Stromal tumour and peripheral leucocyte DNAs from our patient were examined for loss of heterozygosity using the PYGM microsatellite polymorphism and an intragenic polymorphism (D418D in exon 9) in the MEN-1 gene. We showed no evidence for loss of the wild-type MEN-1 allele in GIST. The MEN-1 germline inactivating mutation 1607delA-ter558 in exon 10 was detected in the stromal tumour DNA, but no somatic mutation in the wild-type MEN-1 allele in GIST DNA was detected. Occurrence of GIST could be consistent with the possibility that this MEN-1-related uncommon neoplasm arose independently by a mechanism unrelated to the MEN-1 gene.

Abstract
BACKGROUND AND AIMS Argon beam coagulation is an innovative no-touch electrocoagulation technique in which high-frequency monopolar alternating current is delivered to the tissue through ionized argon gas. The aim of this prospective study was to evaluate the efficacy and safety of argon plasma coagulation (APC) for the treatment of hemorrhagic digestive vascular malformations and hemorrhagic radiation proctosigmoiditis. METHODS AND PATIENTS From March 1998 through April 1999, we used endoscopic APC (ERBE, Lyon, France, argon gas source ICC 300, high-frequency electrosurgical generator ICC 200, gas flow 1 L/min, power setting 50 W) to treat 39 consecutive patients (mean age 70.3 +/- 10 years). The indications for treatment were anemia (n =10), active or oozing haemorrhage (n =15) from digestive angiodysplastic lesions (n =25), hemorrhagic antral telangiectatic vascular lesions (n =2), and hemorrhagic radiation proctosigmoiditis (n =12) after failure of medical treatments (5-aminosalicylic acid, corticosteroids, or sucralfate enemas). The efficacy of APC treatment was evaluated on symptoms, transfusion requirement, bleeding recurrence, hemoglobin value before and 6 months after APC therapy. RESULTS On the average, 1 +/- 0.5 sessions per patient was required to treat digestive vascular malformations. Definitive haemostasis of digestive angiodysplastic lesions with active or oozing haemorrhage was achieved in one session in all patients. No bleeding recurrence was observed during the follow-up period of 6 months. Anemia recurrence was observed in 2 patients (7%). Average hemoglobin levels recorded before and 6 months after APC therapy were 78.8 +/- 21.2 g/L and 108 +/- 13.7 g/L, respectively (P<0.05). On the average, 2.8 +/- 0.8 sessions per patient were required to treat hemorrhagic radiation proctosigmoiditis. Ten patients (83%) reported improvement or cessation of rectal bleeding, most of them immediately after APC therapy. Endoscopic control was performed one month after APC therapy and showed complete disappearance of lesions in 8 patients (66%). Average hemoglobin levels recorded before and 6 months after APC therapy were of 102.7 +/- 21 g/L and 120 +/- 19.5 g/L, respectively (P <0.05). Complications were observed in 5 cases (13%): pneumoperitoneum in 2 cases, chronic rectal ulcerations in 2 cases, and nonsymptomatic rectal stenosis in 1 case. CONCLUSION APC appears to be a simple, safe, and effective technique in the management of hemorrhagic radiation-induced proctosigmoiditis and hemorrhagic lesions.

Abstract
Fedotozine, a kappa opioid agonist, reverses digestive ileus caused by acetic acid (AA)-induced visceral pain in rats. The aims of this study were: to map, in conscious rats, central pathways activated by AA using Fos as a marker of neuronal activation; to characterize primary afferent fibres involved in this activation; and to investigate the effect of fedotozine on AA-induced Fos expression. AA (0.6%; 10 mL kg-1) was injected i.p. in conscious rats either untreated; pretreated 14 days before with capsaicin; pretreated 20 min previously with fedotozine; or pretreated 2 h prior to fedotozine with the kappa-antagonist nor-binaltorphimine (nor-BNI). Controls received the vehicle alone. 60 min after injection of AA, rats were processed for Fos immunohistochemistry. Visceral pain was assessed by counting abdominal cramps. AA induced Fos in the thoraco-lumbar spinal cord (laminae I, V, VII and X) and numerous brain structures such as the nucleus tractus solitarius, and paraventricular nucleus (PVN) of the hypothalamus, whereas almost no Fos labelling was observed in controls. Capsaicin pretreatment blocked AA-induced Fos in all structures tested. Fedotozine significantly decreased AA-induced abdominal cramps and Fos immunoreactivity in the spinal cord and PVN, this effect being reversed by nor-BNI pretreatment. AA induces Fos in the spinal cord and numerous brain nucuei, some of which are involved in the control of digestive motility in rats. This effect is mediated through capsaicin-sensitive afferent fibres and prevented by fedotozine most likely through a peripheral action on visceral afferents.

Abstract
BACKGROUND AND PURPOSE Although the central processing of somatic pain has been dealt with in numerous brain imaging studies, the neural correlates of visceral pain have received much more limited attention. Our goal was to assess the feasibility of detecting brain activation patterns induced by rectal pain by means of functional MR imaging. We hypothesized that the cerebral processing of rectal pain would exhibit strong similarities with the central processing of somatic pain. METHODS Functional MR imaging data were obtained from eight healthy subjects. A block paradigm was applied. Rectal pain was induced by inflating a latex balloon catheter that had been inserted into the rectum. Functional responses were established by means of cross-correlation analysis. RESULTS Activation was detected within the anterior cingulate gyrus, the prefrontal cortex, the insular cortex, the sensory-motor cortex, the inferior parietal lobule, the posterior cingulate gyrus, and the visual cortex. CONCLUSION Functional MR imaging of visceral pain is feasible in healthy subjects. The activation patterns observed in this study support the hypothesis that the cerebral processing of visceral pain involves multiple components, similar to the central processing of somatic pain. Our results constitute a first step toward the identification of possible aberrations in the activation patterns of patients suffering from visceral hypersensitivity.

Abstract
OBJECTIVES The study objectives were to describe (a) adaptation trajectories of elderly persons treated on a transitional unit for deconditioning and tracked after their return to the community, (b) an individualized adaptation-based intervention provided to selected elderly persons in addition to protocol-based treatment for deconditioning, (c) goals and outcomes of these two interventions, and (d) contrasting perceptions of outcomes by elderly persons, their family members, and their therapists. METHOD A longitudinal qualitative design was used to track 8 participants from transitional unit to community. Data on the protocol-based intervention were obtained from chart review and therapist interviews. Data on the adaptation-based intervention were obtained from the Client-Centered Evaluation and Community Adaptive Planning Assessment, which were used for goal setting and problem solving. In the community, contrasting perspectives on outcomes were obtained from the participants, their family members, and their therapists through semistructured interviews. RESULTS Participants' adaptation trajectories revealed that half relocated to new living arrangements after discharge from the transitional unit. At the time of follow-up, 91% of the protocol-based goals and 100% of the adaptation-based goals had been met in some fashion, with modification in the goal or development of new solutions in some cases. Outcomes valued by the participants were returning to former occupations and relationships; family members valued getting quality care for the participant; and therapists valued improvement in strength, endurance, and increased independence in activities of daily living (ADL). CONCLUSION Findings support use of an individualized consultative intervention that addresses occupational performance areas and performance contexts combined with a protocol-based, hands-on intervention that addresses performance components and basic ADL for elderly persons with multiple chronic illnesses.

Abstract
UNLABELLED The aim of this study was to define the normal manometric pattern of esophageal motility in response to food ingestion and to evaluate the contribution of esophageal manometry in the management of patients complaining of functional dysphagia. PATIENTS AND METHODS Twenty-one healthy volunteers and 25 consecutive patients complaining of functional dysphagia with normal conventional esophageal manometry were included in this prospective study. An event marker was used to study the relationship between dysphagia and motility events. RESULTS Twenty-two out of 25 patients (88%) reported dysphagia during esophageal manometry with food ingestion, while none complained of dysphagia during conventional esophageal manometry. Significantly, food ingestion induced in healthy volunteers and in patients: an increase in the amplitude and duration of esophageal body peristaltic contractions, and a decrease in their propagation speed; an increase in the basal pressure and a decrease in the relaxation percentage of the lower esophageal sphincter during deglutition. The percentage of solid swallows with one or several of the 7 abnormal motility patterns studied prospectively was significantly higher among patients (53.7%) than among healthy volunteers (4.3%) (P < 0.0001); it was also significantly higher among patients during swallows with dysphagia (70.1%) than without dysphagia (33.6%) (P < 0.0001). CONCLUSION Esophageal manometry with food ingestion is an effective means of defining abnormal motility patterns and their relationship with dysphagia during functional dysphagia.

Abstract
UNLABELLED The treatment of esophageal carcinoma is frequently palliative. The aims of this prospective study were to evaluate the functional results of covered self expanding esophageal metal stents in patients with malignant obstruction of the esophagus and to compare two models of stent. PATIENTS AND METHODS From April 1994 to August 1996, 32 patients were treated with 35 metal stents (Cook Z Stent Wilson Cook: n = 21; Ultraflex Boston Scientific: n = 14). Ten patients had a fistula. Previous treatment was effective in 30 patients. Initial score of dysphagia was 2.68 +/- 0.7. Initial score of Karnofsky was 60 +/- 10%. The metal stents could be placed in 100% of cases. The 30-day mortality was 0%. The morbidity of device placement of metal stents was 28%. The treatment of fistulas was effective without complication in 100% of cases. At month 3, we observed a significant decrease of dysphagia score (0.43 +/- 0.25) and a significant increase of Karnofsky score (75 +/- 10%) (P < 0.001). The mean duration of hospitalization was 5.4 +/- 1.3 days. During mean follow-up of 18 +/- 3.5 months, 14 patients (44%) died. Any difference concerning mortality and functional results was observed between 2 kinds of metal stents. We only observed a significant decrease of retrosternal pain in patients treated with Ultraflex prothesis. CONCLUSION Self-expanding esophageal metal stents are a simple and effective palliative treatment of malignant obstruction of the esophagus. However, their high cost need other cost-efficacy studies to define their indications.

Abstract
Fifty-four patients examined for noncardiac chest pain (NCCP), showing no esophageal motor disorder or gastroesophageal reflux disease compatible with NCCP, were subjected to an intraesophageal balloon distension test and a study of the belching reflex provoked by intraesophageal air injection. Thirty-three control subjects were also studied, allowing us to define high-threshold belchers (group I) as those who belched during two of three 40-ml distensions and low-threshold belchers (group II) as those who did not. The balloon distension test induced NCCP in 64% of the patients in group I, and in 14% of the patients in group II (P < 0.01). High-threshold belching was a factor favoring the positivity of the balloon distension test. This result supports the hypothesis that esophageal distension by air due to a belching disorder may be the mechanism responsible for NCCP in some patients with an abnormal sensitivity to balloon distension.

Abstract
This study was conducted to identify factors predicting favourable outcome after ranitidine 300 mg o.d. treatment for oesophagitis. Patients with grade 2 or 3 erosive oesophagitis were included in the study. Each investigator recruited 2 patients with the same grade of lesion in order to minimize bias in assessing symptoms. All patients received the same 6-week treatment: 300 mg ranitidine daily in the form of an effervescent tablet after the dinner. Symptomatology was assessed after 2 and 6 weeks of treatment and endoscopy was performed at the end of the treatment period. A successful outcome was defined as the absence of erosive lesions (grade 0 or 1). A total of 515 patients were recruited and 500 retained for analysis (15 patients did not follow the treatment protocol correctly): 267 grade 2 and 233 grade 3 (mean age: 52.5 years; sex ratio M/F: 1.7). Patients with grade 3 oesophagitis had more severe symptoms; hiatal hernia was also more frequent in this group. Alcohol intake and smoking habits were similar in both groups. After 6 weeks of treatment, successful healing was observed in 87 percent of the grade 2 patients and in 72 percent of the grade 3 patients. Three factors predicting successful outcome were found: grade 2 (odds ratio (OR): 1.50; p = 0.001), symptom duration less than 30 days after treatment onset (OR: 1.50; p = 0.001) and complete relief of symptoms after two weeks of treatment (OR: 1.31; p = 0.03). Disease history and the course of symptoms during treatment with ranitidine could help predict endoscopic outcome of oesophagitis.

Abstract
The association of chronic intestinal pseudoobstruction with ophthalmoplegia has been reported previously in visceral myopathies. We report a case of this association in which muscle mitochondria had a crystalline appearance, a dense core, and decreased cytochrome c oxidase and succinate cytochrome c reductase activities. The absence of evident mitochondrial DNA deletion in the skeletal muscle of this patient does not exclude the possibility of localized deletion or mutation of mitochondrial DNA in digestive muscle.

Abstract
In a double-blind, randomized, comparative trial of the prokinetic drug cisapride and the H2-blocker cimetidine, mucosal healing and changes in symptoms of gastroesophageal reflux were evaluated in patients with erosive reflux esophagitis. The patients were treated with either cisapride, 10 mg four times a day (N = 36) or cimetidine, 400 mg four times a day (N = 37) for six weeks, or for 12 weeks if mucosal healing was not obtained by week 6. Upon entry, two thirds of the patients in each group had grade I (Savary-Miller) esophagitis, and the remainder grade II or III. At the end of treatment, endoscopy showed mucosal healing in 56% (38-72%; 95% confidence interval) of cisapride and 57% (39-73%; 95% confidence interval) of cimetidine patients. After six weeks, both drugs significantly (P less than 0.01) decreased the intensity and frequency of heartburn, regurgitation, and the postural syndrome. No significant intergroup differences were found regarding endoscopic parameters or the improvement of heartburn and regurgitation. Concomitant antacid use was also comparable. Adverse effects were reported by four cisapride and nine cimetidine patients. These results indicate that the effects of cisapride compare well with those of cimetidine in terms of both esophageal mucosal healing and symptom relief.

Abstract
A quantitatively and/or qualitatively abnormal duodenogastric reflux (DGR) could be involved in the pathogenesis of nonulcer dyspepsia (NUD). The aims of this prospective study were to look for (1) a pathological DGR profile during fasting and (2) an eventual correlation between DGR profile and clinical symptoms. Twenty-six NUD patients were investigated. Seven other operated patients with a surgical procedure facilitating DGR episodes and 27 healthy volunteers served as control groups. A clinical score was determined for each patient from a standardized questionnaire. Gastric aspiration was performed for 6 hr in fasting subjects. The aspirates were pooled into 17 samples. In each sample the concentration and the output of total bile acids was determined. If the concentration was larger than 30 mumol/liter in pooled samples, the concentrations of free bile acids and the distribution of the conjugated bile acids was determined. The percentage of aliquots with a total bile acid concentration larger than 50 mumol/liter (without upper limit), and the percentage with a concentration larger than 2500 mumol/liter was also obtained. No significant difference was demonstrated between the healthy volunteers and NUD patients, whatever the parameter considered. However, there was a significant increase in each of the quantitative parameters for the group of operated patients in comparison with the NUD patient group. No significant correlation was found between the clinical score and the DGR profile in NUD patients. Apparently, DGR episodes do not play a primary role in the pathogenesis of NUD.

Abstract
Cholescintigraphy with technetium 99m hydroxy imino diacetic acid (99mTc-HIDA) was used to study gallbladder emptying (GE) and duodenogastric reflux (DGR) simultaneously during the postprandial period in humans. Two groups of subjects were examined prospectively; one was a group of healthy volunteers (n = 14) and the other a group of patients with non-ulcerous dyspepsia (NUD) (n = 22). Symptoms were quantified using a clinical score (CS). GE kinetics was quantified according to two indices. DGR episodes were detected by an image-subtraction method and quantified. The group of patients with NUD showed significant early acceleration of GE (P less than 0.01). One DGR episode equivalent to 1% of the injected dose was observed in 1 of the 14 control subjects, and greater than 1% in 3 of the 22 NUD patients. However, there was no correlation between the CS, GE kinetics and DGR episodes. The physiopathological mechanism and clinical significance of these digestive motility anomalies remain to be demonstrated.

Abstract
A randomized double-blind clinical trial of aluminum phosphate versus ranitidine in the treatment of noncomplicated acute duodenal ulcer has been conducted in 91 patients. After randomization the 42 patients of the aluminum phosphate group were comparable to the 49 patients of the ranitidine group. At 4 weeks, 6 patients were not endoscoped and according to the intention-to-treat method they were considered as treatment failure. The endoscopy showed a 60% healing rate in the aluminum phosphate group (25/42) versus 55% in the ranitidine group (27/49); this difference was not significant. Among the factors assessed, only one, the round shape of the ulcer, was significantly and independently associated with ulcer healing in a multidimensional analysis. In conclusion, this double-blind trial showed that aluminum phosphate is an effective, save and cheap treatment of acute duodenal ulcer.

Abstract
Duodeno-gastric reflux might be responsible for a number of acute and/or chronic diseases of the oesophagus and stomach. However, no consensus has emerged from published clinical or experimental studies concerning the relationship between duodeno-gastric reflux and digestive tract disease. This inconsistency could be partly linked to the difficulties in detection and quantification of duodeno-gastric reflux episodes and, consequently, in differentiation between physiological and pathological reflux. A critical review of the different diagnostic methods is therefore submitted here. An application of duodeno-gastric reflux evaluation to the inter-digestive period in non-ulcerous dyspepsia was carried out. The preliminary results of this prospective study do not favor an immediate responsibility of a quantitatively abnormal fasting reflux in non-ulcerous dyspepsia. However, other applications of duodeno-gastric reflux analysis taking into account not only the quantitative aspect but also the composition of the reflux material, (selective bile acids, phospholipids, etc.) are necessary.

Abstract
The aims of this prospective study were a) to evaluate the diagnostic value of the urease test for the detection of C. pylori in gastric biopsy specimens, b) to specify the prevalence of C. pylori in a sample of 74 patients from the Grenoble area undergoing upper gastrointestinal endoscopy, c) to analyze the density of bacteria according to the biopsy site (antrum, body, edges of ulcer), d) to demonstrate any possible correlation between the histologic state of the antral and body mucosa and the presence of C. pylori. An antral biopsy was taken for the urease test during endoscopy. Biopsies were also taken from the body, the antrum and the edges of gastric or duodenal ulcers for bacterial and histologic studies, and urease test in the bacterial laboratory. The sensitivity and the specificity of the urease test during endoscopy varied according to the delay in observation of the color change. They were 0.81 and 0.84, respectively, at 2 h 30. The sensitivity and specificity of the urease test in the bacterial laboratory were 0.67 and 0.95, respectively, for the same delay. The global prevalence of C. pylori was 51 p. 100: it was 42 p. 100 in the absence of ulcer, 67 p. 100 in the presence of gastric ulcer, and 71 p. 100 in the presence of duodenal ulcer (p less than 0.05 compared to the group without ulcer).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Duodenogastric reflux (DGR) could be implicated in several esophageal and gastric diseases. Establishing its pathophysiological role however is difficult because of the problems in the demonstration and quantification of DGR episodes. The aim of this study was to improve a scintigraphic method of detection and quantification of DGR episodes during the postprandial period in man. The study was carried out in 14 control subjects (7 males and 7 females, median age = 25 years, range: 22-35 years). As scintigraphic recording was continuous during 150 min, all DGR episodes were revealed. In order to improve visual detection of DGR episodes, images were treated by a computerized image subtraction method. The visual detection limit of DGR episodes determined by comparison to test images was 0.6 p. 100 of the dose injected intravenously or 17 microCi. A DGR episode was demonstrated in one of the 14 control subjects. The quantity of refluxed liquid was estimated, in this case, at 30 microCi, and the duration of the reflux greater than 2 min. Continuous scintigraphic recording in association with a computer based technique of image subtraction seems to improve scintigraphic performance in the study of DGR episodes under pathological conditions.

Abstract
The purpose of this study was to ascertain the pharmacological effectiveness of sodium alginate liquid in the treatment of gastroesophageal acid reflux. The pharmacological test selected was 3 hours postprandial oesophageal pH, because of the physico-chemical properties of this drug. Twenty-one patients of both sexes were included in this study. The initial pH measurement served both as inclusion criteria, by confirming the presence of gastric acid reflux, and as reference for the evaluation of the effect of sodium alginate liquid by a second pH determination after treatment. After treatment with sodium alginate liquid, the number and mean duration of episodes of reflux, as well as the time spent at each pH level, had significantly decreased as compared to the initial value. The gastroesophageal reflux score was significantly reduced during the second hour in recumbent posture, but none of the different parameters studied separately (number and mean duration of episodes of reflux and time spent at each pH level) was significantly decreased. This study demonstrates the pharmacological effectiveness of the drug during the post prandial period and indicates that it is more effective in upright than in supine position.

Abstract
Several studies have been performed to examine the problem of diagnosing gastroduodenal reflux (GDR). No single method is widely accepted. The aim of this work was to evaluate the diagnostic value of gastric pHmetry in this regard. A gastric aspiration probe attached to a combined glass electrode was placed in the stomach of 24 patients, with its distal tip located between 9 and 12 cm below the cardia. One ml samples of gastric juice were taken from 8 of the patients every 30 min for 15 h and as well as, every time a spontaneous alkalinization (SA) (defined by a pH greater than or equal to 4 for at least 1 min) was observed. The pH of each sample was measured by colorimetry whereas the concentration of total biliary acids (CTBA) was evaluated by the fluorimetric method (Kit Sterognost 3 alpha Flu); pH value measured via the intragastric electrode during aspiration was also recorded (protocol A). Continuous gastric aspiration was carried out in the remaining 16 patients for the entire duration of the test (6 h) which was divided into periods of 20 min. Apart from the parameters evaluated during protocol A, the percentage of time during which the stomach had a pH greater than or equal to 4 was recorded, as well as the quantity of total biliary acids collected over the 20 min periods (protocol B). Correlation studies were carried out using the Kendall tau and Spearman tests. Percentages were compared using the chi 2 test.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Twenty-four hour pH monitoring is used increasingly as a technique for diagnosis of gastro-esophageal reflux (GER). The Synectics recording apparatus (Stockholm, Sweden) was used in 27 ambulatory control subjects in order to: identify the variations of the data-dependent factors (electrodes, buffer solutions, calibration, placement of esophageal electrode). The consequences of these variations were evaluated by studying the measurement deflection after 24 h, baseline variations, and a comparative double pH esophageal recording with reference equipment for 3 h postprandial; to provide normal values for several parameters of GER measurement under the conditions of this study (total number of reflux, number of reflux episodes longer than 5 min, duration of the longest reflux, percentage of time during which pH was less than 4.0). Important interindividual variations were observed. When interpreting the results provided by this type of apparatus, one should take into account these large variations due, first, to the technique used and second, to the conditions of ambulatory recording.

Abstract
Several studies concerning the relationships between gastroesophageal reflux (GOR), gastric emptying and esophageal motility are available. So far, results have been contradictory. The purpose of this work was to study gastric emptying in patients with GOR; to search for simultaneous esophageal motility disorders and to specify their type and frequency; to establish a potential relationship between motor disorders of the esophagus and the stomach in these patients. Thirty-two consecutive patients were selected according to clinical criteria, i.e. presence of at least two of the three characteristic symptoms of GOR, and the data of a three-hour post-prandial pH-metry. Gastric stasis related clinical manifestations (nausea, post-prandial vomiting, sensation of abdominal distension or of post-prandial epigastric fullness) were also searched for in all patients. A gastroscopy allowed to score esophagitis in each case. All patients, including adult controls underwent an esophageal manometry as well as a radionuclide determination of gastric emptying, after isotopic labelling of the solid (S) and liquid (L) phases of a test meal. The results showed that there was no significant modification of gastric emptying of the S and L phases of the meal in the group of patients with GOR whatever the intensity of the reflux, judged on the pH-metry results and the endoscopic data. Thus the average time of gastric half-emptying of S and L was respectively 115 and 52 min for the patients vs 111 and 51 min for the control group. As well, no correlation was found between the gastric emptying parameters and the presence or absence of clinical signs of gastric stasis or the amplitude of esophageal contraction waves. On an individual basis, two patients showed a significant decrease in gastric emptying of either the S or L phases without any attendant modification in the kinetics of the other. These results suggest that, in the adult, gastric emptying cannot be considered to be a determining factor of GOR and there are no diffuse motility disorders of the upper digestive tract during this illness.

Abstract
Fifty-five consecutive subjects with Raynaud's phenomenon were submitted to esophageal manometry. According to the results of clinical examination and periungual capillaroscopy, they were divided into three groups: sixteen patients presented presclerodermal Raynaud's phenomenon, and nineteen, systemic sclerosis; twenty others had Raynaud's disease. Twenty volunteers formed the control group. Esophageal motor disorders were observed in the group with presclerodermal Raynaud's phenomenon, affecting the esophageal lower sphincter and the peristalsis of the body of the esophagus. In the group with systemic sclerosis, these motor disorders were associated with alterations in the amplitude and the duration of contractions. Esophageal motility was normal in subjects with Raynaud's disease. We can conclude that: 1) esophageal motor disorders can be seen in presclerodermal Raynaud's phenomenon. The kind of abnormalities observed at this stage of the disease are in favor of an early alteration of the neurogenic component of esophageal motility; 2) there is no relationship between esophageal motor disorders and Raynaud's phenomenon in scleroderma.
