Abstract
BACKGROUND In 2006, bevacizumab, a targeted therapy agent was combined with FOLFIRI for the firstline treatment of patients with unresectable metastatic colorectal cancer. METHODS/RESULTS A study on a homogenous series of 111 patients from the Brittany and Pays de la Loire areas who received bevacizumab-FOLFIRI as first-line treatment in 2006 showed the following results: 51 responses, 29 stabilisations, 21 progressions and 10 cases of toxicity prior to assessment. Median overall survival (OS) was 25.1 months and median progression-free survival was 10.2 months. Surgery secondary to treatment tripled median OS which reached 59.2 months in resected patients versus 18.8 months in unresected patients. Comparison of patients aged more or less than 70 years showed no differences in terms of benefits or risks. CONCLUSION Bevacizumab-FOLFIRI could be administered as part of a routine care protocol to elderly patients previously evaluated by a geriatric assessment and validated by a multidisciplinary staff.

Abstract
Rectal duplication cyst is a rare entity that accounts for approximately 4% of all alimentary tract duplications. To the best of our knowledge, the presented cases are the first reports in the English literature of rectal duplication cyst resection by transanal endoscopic microsurgery. We present two patients; both are 41-year-old women with a palpable rectal mass. Workup revealed a submucosal posterior mass that was then resected by transanal endoscopic microsurgery. The pathology report described cystic lesions with squamous and columnar epithelium and segments of smooth muscle. These findings were compatible with rectal duplication cyst. Our limited experience showed good results with minimal morbidity and mortality for resection of rectal duplication cysts of limited size with no evidence of malignancy.

Abstract
AIMS To report on a family with five members who carry the A3243G mutation in mitochondrial tRNA for leucine 1 (MTTL1) and present with diabetes, chronic intestinal pseudo-obstruction (CIPO) and recurrent pancreatitis, and to screen for this mutation in a cohort of 36 unrelated patients with recurrent pancreatitis. METHODS The mutation was quantified in several tissue samples from patients. Respiratory chain activity was studied in muscle biopsies and fibroblast cultures. In addition, the thymidine phosphorylase gene (TP) involved in mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) and three genes involved in chronic pancreatitis - PRSS1, SPINK1 and CFTR - were sequenced in affected patients. Finally, the MTTL1 gene was examined in 36 unrelated patients who had recurrent pancreatitis, but no mutations in the PRSS1 and SPINK1 genes. RESULTS Heteroplasmy for the mtDNA A3243G mutation was found in all tissue samples from these patients, but no mutations were found in the genes coding for thymidine phosphorylase, PRSS1, SPINK1 and CFTR. Also, none of the 36 unrelated patients with recurrent pancreatitis were carrying any MTTL1 mutations. CONCLUSION The mtDNA A3243G mutation associated with the gastrointestinal manifestations observed in the affected family should be regarded as a possible cause of CIPO and unexplained recurrent pancreatitis. However, the mutation is probably only weakly involved in cases of isolated recurrent pancreatitis.

Abstract
Since the introduction of laparoscopy into colorectal surgery in the early 1990s, almost every procedure was attempted laparoscopically. Performing laparoscopic colectomies in patients with inflammatory bowel diseases (IBD) might prove to be extremely challenging due to the inflammatory features of the diseases and the potential complications they may pose; dealing with inflammatory masses, fistulas and abscesses, short and thick mesentery, friable bowel wall, and the need to operate in all the abdominal quadrants, mobilizing long segments of large and small bowel and controlling multiple large blood vessels is not an easy task. Consequently, many very experienced surgical groups conducted numerous trials in an attempt to determine whether laparoscopy in IBD is indeed beneficial or not. The focus of this review is minimally invasive procedures in patients with ulcerative colitis (UC) and Crohn's disease (CD).

Abstract
BACKGROUND The steadily increasing age of the population mandates that potential benefits of new techniques and technologies be considered for older patients. AIM To analyze the short-term outcomes of laparoscopic (LAP) colorectal surgery in elderly compared to younger patients, and to patients who underwent laparotomy (OP). METHODS A retrospective analysis of patients who underwent elective sigmoid colectomies for diverticular disease or ileo-colic resections for benign disorders; patients with stomas were excluded. There were two groups: age < 65 years (A) and age >or= 65 years (B). Parameters included demographics, body mass index (BMI), length of operation (LO), incision length (LI), length of hospitalization (LOS), morbidity and mortality. RESULTS 641 patients (M/F - 292/349) were included between July 1991 and June 2006; 407 in group A and 234 in group B. There were significantly more LAP procedures in group A (244/407 - 60%) than in group B (106/234 - 45%) - p = 0.0003. Conversion rates were similar: 61/244 (25%) in group A, and 25/106 (24%) in group B (p = 0.78). There was no difference in LO between the groups in any type of operation. LOS was shorter in patients in group A who underwent OP: 7.1 (3-17) days versus 8.7 (4-22) days in group B (p <0.0001), and LAP: 5.3 (2-19) days versus 6.4 (2-34) days in group B (p = 0.01). In both groups LOS in the LAP group was significantly shorter than in OP group. There were no significant differences in major complications or mortality between the two groups; however, the complication rates in the OP groups were significantly higher than in LAP and CON combined (p = 0.003). CONCLUSIONS Elderly patients who undergo LAP have a significantly shorter LOS and fewer complications compared to elderly patients who undergo OP. Laparoscopy should be considered in all patients in whom ileo-colic or sigmoid resection is planned regardless of age.

Abstract
BACKGROUND Surgery for isolated internal rectal intussusception is controversial due to high morbidity. Therefore, there is interest in other forms of treatment that are safe and effective. The aim of this study was to determine outcome and identify predictors for success of biofeedback therapy in patients with rectal intussusception. METHODS We retrospectively evaluated the results of electromyography (EMG)-based biofeedback in 34 patients with rectal intussusception without any other major pelvic floor or colonic physiologic disorder. RESULTS A total of 34 patients (7 men) had undergone at least 2 biofeedback sessions. The patients had a mean age of 68.5 years (SD=11.4 years). In the 27 patients with constipation, the frequency of weekly spontaneous bowel movements (mean+/-SD) was 2.0+/-6.8 before and 4.1+/-4.6 after biofeedback (p<0.05). The frequency of weekly assisted bowel movements decreased from 3.8+/-3.5 before to 1.5+/-2.2 after therapy (p<0.005). The number of patients who experienced incomplete evacuation decreased from 17 (63%) to 9 (33%) (p<0.05). Thirty-three percent of patients had complete resolution of the symptoms, 19% had partial improvement, and 48% had no improvement. Patients with constipation lasting less than nine years had a 78% success rate vs. 13% in patients who were constipated more than 9 years (p<0.01). In seven patients with incontinence, the frequency of daily incontinence episodes decreased from 1.0+/-0.7 before to 0.07+/-0.06 after biofeedback (p<0.05). The fecal incontinence score decreased from 13.1+/-4.2 before to 4.6+/-3.6 after treatment (p<0.005). Two patients (29%) were completely continent following biofeedback, 2 had partial improvement, and 3 (43%) had no significant improvement. There was no mortality in either group. CONCLUSIONS Biofeedback is a safe and effective treatment option for constipation and fecal incontinence due to rectal intussusception in patients who are willing to complete the course of treatment. Long-standing constipation is less effectively cured by biofeedback.

Abstract
Sensory rhodopsin II (SRII) from Halobacterium salinarum is heterologously expressed in Escherichia coli with a yield of 3-4 mg of purified SRII per liter cell culture. UV/Vis absorption spectroscopy display bands characteristic for native SRII. The resonance Raman spectrum provides evidence for a strongly hydrogen-bonded Schiff base like in mammalian rhodopsin but unlike to the homologous pSRII from Natronobacterium pharaonis. Laser flash spectroscopy indicates that SRII in detergent as well as after reconstitution into polar lipids shows its typical photochemical properties with prolonged photocycle kinetics. The first functional heterologous expression of SRII from H. salinarum provides the basis for studies with its cognate transducer HtrII to investigate the molecular processes involved in phototransduction as well as in chemotransduction.

Abstract
Many women who are at risk for HIV do not regularly use condoms, particularly with their main partners. In this paper we examine factors related to self-efficacy for condom use with main and other partners and self-efficacy for birth control in 2864 women interviewed in five urban high-risk communities. Limited social and economic resources, dependence on a main partner, and risk factors, including exchanging sex for money or drugs and binge drinking, were found to be negatively related to self-efficacy. Segmentation analysis identified groups of women with low self-efficacy who should be the focus of preventive interventions.

Abstract
AIM To evaluate in a prospective study the prognostic factors of recurrent bleeding and mortality in patients presenting with high risk peptic ulcer bleeding routinely treated by endoscopic hemostasis. PATIENTS AND METHODS A multicenter study was carried out in 8 Western French hospitals in 144 patients with gastrointestinal bleeding peptic from ulcer type I or IIa, b as defined by Forrest classification. Thirty four and 38 parameters were studied respectively in order to predict recurrent bleeding and death. Significant predictive factors (P < 0.1) in univariate analysis were entered in a multivariate logistic regression analysis. RESULTS Endoscopic hemostasis was performed in 108 of 144 cases (75%). Recurrent bleeding and death occurred in 39 (28%) and 22 cases (15%), respectively. By multivariate analysis, the only predictor of rebleeding was hypovolemia at admission. Predictors of death were ASA score, cardiovascular Goldman score and recurrent bleeding. In this study, prevalence of Helicobacter pylori infection was low (41%) but was not a predictive factor. CONCLUSIONS In a selected population of peptic ulcer bleeding patients with high risk of rebleeding, prevalence of recurrent bleeding and death remains rather high, despite routine endoscopic hemostasis. In the era of endoscopic hemostasis, clinical parameters remain the best prognostic factors of peptic ulcer bleeding outcome.

Abstract
OBJECTIVES This study examined the effects of a multisite community-level HIV prevention intervention on women's condom-use behaviors. METHODS The theory-based behavioral intervention was implemented with low-income, primarily African American women in 4 urban communities. It was evaluated with data from pre- and postintervention cross-sectional surveys in matched intervention and comparison communities. RESULTS At baseline, 68% of the women had no intention of using condoms with their main partners and 70% were not using condoms consistently with other partners. After 2 years of intervention activities, increases in rates of talking with main partners about condoms were significantly larger in intervention communities than in comparison communities (P = .03). Intervention communities also had significant increases in the proportion of women who had tried to get their main partners to use condoms (P = .01). The trends for condom use with other partners were similar but nonsignificant. CONCLUSIONS Many women at risk for HIV infection are still not using condoms. Community-level interventions may be an effective way to reach large numbers of women and change their condom-use behaviors, particularly their behaviors with regard to communication with main sex partners.

Abstract
We report a prospective randomized multicenter trial that tested the efficacy of combining ursodeoxycholic acid and norfloxacin in the prevention of polyethylene stent clogging in patients with obstructive jaundice due to an unresectable malignancy at the level of the common bile duct. After insertion of a 10-Fr straight polyethylene stent, patients were allocated to receive oral treatment with ursodeoxycholic acid and norfloxacin, or conservative treatment. The primary outcome measure was stent blockage within six months. Thirty-three patients (group I) received ursodeoxycholic acid and norfloxacin, and 29 received conservative treatment (group II). At six months, cumulative stent patency rate did not differ significantly between group I (47+/-11%, mean +/- SE, median 149 days) and group II patients (24+/-10%, mean +/- SE, median 100 days, P = 0.23, log-rank test). Four stents were clogged by ursodeoxycholic acid. Survival did not differ between the two groups. Combined therapy with ursodeoxycholic acid and norfloxacin failed to improve stent patency. Moreover, ursodeoxycholic acid can cause stent obstruction.

Abstract
BACKGROUND AND PURPOSE Sonography, CT, and MR imaging are commonly used to screen for neonatal intracranial ischemia and hemorrhage, yet few studies have attempted to determine which imaging technique is best suited for this purpose. The goals of this study were to compare sonography with CT and MR imaging prospectively for the detection of intracranial ischemia or hemorrhage and to determine the prognostic value(s) of neuroimaging in neonates suspected of having hypoxic-ischemic injury (HII). METHODS Forty-seven neonates underwent CT (n = 26) or MR imaging (n = 24) or both (n = 3) within the first month of life for suspected HII. Sonography was performed according to research protocol within an average of 14.4 +/- 9.6 hours of CT or MR imaging. A kappa analysis of interobserver agreement was conducted using three independent observers. Infants underwent neurodevelopmental assessment at ages 2 months (n = 47) and 2 years (n = 26). RESULTS CT and MR imaging had significantly higher interobserver agreement (P < .001) for cortical HII and germinal matrix hemorrhage (GMH) (Grades I and II) compared with sonography. MR imaging and CT revealed 25 instances of HII compared with 13 identified by sonography. MR imaging and CT also revealed 10 instances of intraparenchymal hemorrhage (>1 cm, including Grade IV GMH) compared with sonography, which depicted five. The negative predictive values of neuroimaging, irrespective of technique used, were 53.3% and 58.8% at the 2-month and 2-year follow-up examinations, respectively. CONCLUSION CT and MR imaging have significantly better interobserver agreement for cortical HII and GMH/intraventricular hemorrhage and can reveal more instances of intraparenchymal hemorrhage compared with sonography. The absence of neuroimaging findings on sonograms, CT scans, or MR images does not rule out later neurologic dysfunction.

Abstract
OBJECTIVES Study the effect of hyperbaric oxygen on chronic irradiation induced digestive disorders. PATIENTS AND METHODS A retrospective study was conducted in 36 patients (mean age 66 +/- 11 years) with chronic digestive tract necrosis which had developed a mean 42 months after irradiation therapy. Hyperbaric oxygen therapy was given a mean 17 months after symptom onset: failing healing (n = 9), rectal bleeding (n = 19), profuse diarrhea (n = 9), recurrent anal abscess (n = 1). The severity of the digestive tract radionecrosis was quantified using the Soma-Lent scale. Hyperbaric oxygen therapy was grade 1 (n = 1), grade 2 (n = 11), grade 3 (n = 16), grade 4 (n = 8). RESULTS Thirty-six patients underwent a mean 67 hyperbaric sessions (100% O2, 2.5 atm, 90 min). Three patients died within one month of the first session due to radiation enteritis, a neoplastic process or another concomitant cause. Immediate outcome after hyperbaric oxygen therapy was cure (n = 3) or improvement (n = 16) in 19 patients (53%) and failure in 17 (47%). Long-term results evaluated in 32 subjects with a mean 52 months follow-up were: cure (n = 9) or improvement (n = 12) in 21 patients (66%) and failure in 11 (34%). Nine patients died within a mean 25 months after the end of the hyperbaric sessions. Death was related to digestive tract radionecrosis in 1 case and neoplasia in 5. CONCLUSION Hyperbaric oxygen therapy provides clinical relief in 2 out of 3 patients and can be a useful alternative to conventional treatment in patients with chronic radiation-induced necrosis of the digestive tract.

Abstract
The Women and Infants Demonstration Project is a multisite, behavioral intervention research effort funded by the Centers for Disease Control. The project is evaluating a theory-based, integrated intervention model to increase the use of condoms for prevention of both sexually transmitted diseases (STDs) and unintended pregnancy among women and their partners at risk of infection with HIV. The importance of utilizing carefully targeted, credible and persistent risk reduction interventions to effect lasting behavior change has become evident over the last ten years of the AIDS epidemic. The theory-based intervention components being evaluated in this intervention study involve one-on-one stage-tailored outreach; the development and distribution of community-tailored HIV prevention materials, called role-model stories; and the development of organizational and peer networking, all within a community mobilization framework. This article describes each of the intervention components being evaluated during this 5-year study. Such an intervention effort represents an important contribution in the design of community-level AIDS prevention intervention efforts which support individual-level behavioral changes by women at risk for HIV and other sexually transmitted infections.

Abstract
AIMS The hydrostatic dilatation of the papilla of Vater, or sphincteroclasy, has been recently proposed as an alternative to endoscopic sphincterotomy. Our aim was to assess short term results and follow-up after sphincteroclasy for choledocholithiasis. METHODS From August, 1994 to December, 1996, 52 patients were included for endoscopic therapy of choledocholithiasis (mean age 66 +/- 17 years). Patients were prospectively followed on the short term-period (24 h, 48 h and 30 days) and longer term after treatment (every 6 months) by clinical and biological controls. MAIN RESULTS Forty-eight sphincteroclasies were performed successfully (92.3%). Thirty seven patients had a choledocolithiasis. Eleven were stone-free. Eight had undergone former gastric surgery and 8 had impaired coagulation test. Complete stone clearance was achieved in 98% of patients. Mild pancreatitis were observed in three patients (6.25%). Thirty-day mortality was nil. Long term follow-up (mean 21.4 +/- 7 months) revealed: 2 patients with cholecystitis 6 and 13 months after treatment, one of which was followed 8 months later by a fatal septic shock, and 3 patients with cholangitis, 2 of which in the same patient, 9, 12 and 24 months after sphincteroclasy. The global long term biliary complication rate was 8.4%, 4.2% of which were potentially related to the endoscopic procedure. CONCLUSION Sphincteroclasy is an efficient procedure for the treatment of choledocholithiasis. Its short term results are similar to those of endoscopic sphincterotomy. Complications after 2 years appear to be scarce, but longer follow-up is required before routinely performing sphincteroclasy.

Abstract
The laboratory mouse is the premier model system for studies of mammalian development due to the powerful classical genetic analysis possible (see also the Jackson Laboratory web site, http://www.jax.org/) and the ever-expanding collection of molecular tools. To enhance the utility of the mouse system, we initiated a program to generate a large database of expressed sequence tags (ESTs) that can provide rapid access to genes. Of particular significance was the possibility that cDNA libraries could be prepared from very early stages of development, a situation unrealized in human EST projects. We report here the development of a comprehensive database of ESTs for the mouse. The project, initiated in March 1996, has focused on 5' end sequences from directionally cloned, oligo-dT primed cDNA libraries. As of 23 October 1998, 352,040 sequences had been generated, annotated and deposited in dbEST, where they comprised 93% of the total ESTs available for mouse. EST data are versatile and have been applied to gene identification, comparative sequence analysis, comparative gene mapping and candidate disease gene identification, genome sequence annotation, microarray development and the development of gene-based map resources.

Abstract
This study examined the prevalence of consistent condom use among inner-city women at risk for HIV, measured the distribution of these women across the stages of change for condom use, determined psychosocial factors associated with the stages, and suggested intervention strategies based on the results. The 5-city sample of women aged 15-34 years consisted predominantly of African Americans. Only 18% reported consistent condom use with main partners and 45% with other partners. Logistic regressions compared women in each stage of change with those in higher stages for each partner type. Results indicated that women who practice or intend to practice consistent condom use were more likely to talk with others about condoms, acknowledge the advantages of condoms, have higher self-efficacy for condom use, and indicate that people important to them favored condom use. Intervention approaches are suggested for women in different stages of change for condom use.

Abstract
The aim of this study was to assess retrograd cholangiogram findings and first-line endoscopic sphincterotomy followed by laparoscopic cholecystectomy for the treatment of main bile duct lithiasis. Clinical, biological and echographic criteria predictive of main bile duct lithiasis were observed in 125 patients (32 men, 93 women, mean age 44.2 years) who underwent retrograde cholangiography. Results suggested lithiasis of the main bile duct in 105 case (87.5%) and were confirmed at endoscopic sphincterotomy in 99. There were no deaths; four complications occurred (3 moderate cases of pancreatitis, 1 cholecystitis). Conversion was required in 11.6%, usually because of difficulties in dissecting. No residual lithiasis was observed. Mean duration of hospitalization was 11.4 days. This sequential treatment scheme for main bile duct lithiasis appears to be effective, minimally invasive and safe.

Abstract
The HIV-1 encoded regulatory Rev protein acts to selectively increase the cytoplasmic concentration of incompletely spliced viral mRNAs through interaction with the Rev responsive element (RRE). In addition, the Rev activation domain, believed to be a nuclear export sequence, has been shown to modulate the export of non-RRE containing RNAs (e.g. 5S rRNA, splicesomal U snRNAs). Recent evidence suggests Rev activity depends on interactions with cellular cofactors, leading to speculation that Rev utilizes a cellular RNA and/or a protein export pathway. Rev interactions with cellular cofactors could lead to sequestration of those cofactors from normal cellular activities, suggesting potential Rev effects on cellular gene products and their resultant activity. We have examined the role of Rev in modulating the expression of cellular gene products. Through transient cotransfection assays, we observed a consistent and significant decrease in the levels of luciferase and B-galactosidase activity in the presence of a Rev expressing construct. Cell fractionation studies demonstrated the nuclear retention of the luciferase gene transcripts. Surprisingly, similar effects were observed on constitutively expressed RNAs such as gamma-actin transcripts, and the 18S and 28S rRNAs. These results suggest Rev can disrupt the nuclear export of multiple classes of RNAs.

Abstract
BACKGROUND The aim of this prospective study was to evaluate the interobserver agreement of stigmata of recent hemorrhage of bleeding peptic ulcers. METHODS Sixty-one consecutive adult patients were enrolled in the study and nine (three junior and six senior) endoscopists reviewed standardized video recordings of endoscopic examinations. Interobserver agreement was evaluated using the kappa (kappa) index, intraclass correlation coefficient, and proportion of agreement. Observer bias and poorly trained observers were investigated. RESULTS Interobserver agreement was very good for oozing (kappa = 0.68), good for clot (kappa = 0.51), poor for spurting (kappa = 0.29) and visible vessels (kappa = 0.33), and excellent for the absence of stigmata (kappa = 0.82). Observer bias sometimes occurred and the number of poorly trained observers was low. The kappa indexes were significantly better in senior than in junior investigators: 0.48 +/- 0.16 versus 0.37 +/- 0.26, respectively, p < 0.05. The agreement between the in vivo evaluation and video tape recordings (intraobserver agreement) was good (kappa = 0.60 +/- 0.19). There was no training phenomenon between the first and the second half of the patient group. CONCLUSIONS The endoscopic classification of bleeding ulcers might be simplified by limiting grading to a few classes. Special attention should be paid to the training of endoscopists.

Abstract
BACKGROUND The aim of this study was to prospectively compare the diagnostic accuracy of videoendoscopy, with and without Lugol staining, for the detection of esophageal cancer in alcoholic or smoking patients older than 40 years. METHODS Daily alcohol and tobacco consumption and overt and latent symptoms were noted. The 158 patients included were examined by videoendoscopy and with Lugol dye. RESULTS The mean consumption of alcohol and tobacco was 86 +/- 49 gm/day for 26 +/- 11 years, and 30 +/- 18 pack-years, respectively. Twenty-five patients had no symptoms. Before Lugol staining, 12 patients had endoscopically identified cancerous lesions. After Lugol staining, 13 patients had 17 esophageal cancers, 3 of which were high-grade dysplasia. The prevalence of esophageal cancer was 8.2%: 95% CI [4,14]. Dye-free surfaces were significantly larger than the endoscopic patterns observed before Lugol staining (11.6 +/- 9.2 cm2 vs 1.4 +/- 1.7 cm2; p < 0.02). CONCLUSIONS In an alcoholic smoking population, the prevalence of esophageal cancer detected by endoscopy is high and not related to symptoms described by patients. Lugol staining only moderately improves the diagnostic accuracy of videoendoscopy; its main advantage is the assessment of the mucosal extension of esophageal cancer.

Abstract
BACKGROUND AND STUDY AIMS Due to its lower morbidity, it has been suggested that endoscopic ultrasonography (EUS) might replace endoscopic retrograde cholangiography (ERC) in the management of extrahepatic cholestasis of unknown origin. The present study aimed to compare the diagnostic accuracy of EUS and ERC in the management of cholestasis of unknown origin, taking into account the patient's general status and the necessity of endoscopic therapy. PATIENTS AND METHODS Sixty-eight patients with cholestasis of unknown origin were studied prospectively. EUS followed by ERC was carried out on a blinded basis by two endoscopists; diagnostic and therapeutic suggestions were made after either examination. During the ERC procedure and before withdrawing the tube, the endoscopist provided the final conclusions and carried out appropriate endoscopic treatment. RESULTS A correct diagnosis was obtained with EUS and ERC in 94% and in 92% of cases, respectively (not significant). After EUS, diagnostic ERC was necessary for diagnosis and therapy in 24% and 58% of cases, respectively. After ERC, EUS was requested in 41% of cases. The higher the American Society of Anesthesiologists (ASA) grade, the less it was necessary to perform a complementary investigation. In ASA grade 1 patients, endoscopic therapy was suggested in 38% of cases after EUS and in 33% after ERC (not significant); in ASA grade 3 patients, it was suggested in 93% of cases. CONCLUSIONS The diagnostic sensitivities of EUS and ERC are similar for extrahepatic cholestasis. ERC is first indicated in poor candidates for surgery, since endoscopic therapy is frequently required. In good candidates for surgery, EUS should be carried out first in order to stage a tumor or identify choledocholithiasis.

PATIENTS AND METHODS One hundred nineteen patients (36 men, 86 women; median age 59, range 16-93) were referred for endoscopic retrograde cholangiopancreatography (ERCP) to five centers between 1990 and 1994, and included in the study. The delay between LC and ERCP was 105 +/- 21 days. RESULTS Four types of complications were observed. a) Fifty-seven patients had residual stones or clip migration into the common bile duct (CBD); all were successfully treated with endoscopic sphincterotomy (ES). b) Twelve major injuries to the CBD were diagnosed by ERCP; successful surgical repair was carried out in most of these cases. c) Twenty patients had a partial biliary stricture; endoscopic stenting was attempted as a primary procedure in eight patients, with a satisfactory outcome in five (63%). d) Thirty patients had a bile leak; endoscopic therapy (26 patients) led to recovery in 18 (69%). The benefit of endoscopic treatment was less clear in five (19%); ES failed to bring about improvement in three patients (12%). CONCLUSIONS ERCP is indicated when a biliary complication is suspected after laparoscopic cholecystectomy. Endoscopic sphincterotomy is effective for the treatment of retained stones, clip migration, and bile leakage. Endoscopic stenting may be offered as a primary option in partial CBD strictures.

Abstract
The crystal structure of the neurotoxic phospholipase A2, notexin, revealed three binding sites for sulphate ions which were suggested to be phosphate binding sites of importance for the activity of the toxin. The present investigation shows that the sulphate ion bound to the major binding site alters the structure of residues 60-75. In the absence of sulphate and phosphate, the structure of this loop has a conformation which partly resembles the non-neurotoxic PLA2s. The affinity of notexin for phosphate is 17 microM, as measured by the increase in fluorescence at 345 nm. Since the concentrations of phosphate and sulphate ions in blood plasma are 3 and 1 mM, respectively, the binding site must be occupied under physiological conditions. This major sulphate/phosphate binding site explains the specific affinity labelling by pyridoxal phosphate. Pyridoxal phosphate binds to this anion binding site which allows the reaction with Lys-88 or Lys-89. The structure of notexin in the presence and absence of Ca2+ shows only small local structural differences.

Abstract
BACKGROUND Endoscopic ultrasonography (EUS) has been suggested to investigate portal hypertension (PHT). We compared EUS and endoscopy in the exploration of PHT in cirrhosis. METHODS In 58 patients with cirrhosis and 16 controls, the presence of esophageal varices and gastric varices was recorded by both endoscopy and EUS, peridigestive varices and perforating veins by EUS. Relationships of patterns with each other and with clinical and biologic data were evaluated. RESULTS In patients with cirrhosis: esophageal varices were found by endoscopy and EUS in 88% and 55% of cirrhotic cases (p < 0.01), and gastric varices in 17% and 41%, respectively (p < 0.01). Perforating veins, below the gastroesophageal junction, were diagnosed by EUS in 40% of cases and never in controls. A significant relationship was found between perforating veins and the following patterns: peri-digestive varices, gastric varices at EUS, and esophageal varices at endoscopy. In patients with and without cirrhosis: after multivariate analysis, only esophageal varices at endoscopy were independently related to cirrhosis. However, in Child-Pugh class A patients, both esophageal varices and perforating veins were independently related to cirrhosis (diagnostic accuracy, 92%). CONCLUSIONS EUS is of limited value in the diagnosis of cirrhosis because it gives little additional information to upper gastrointestinal endoscopy. The relationships between perforating veins, varices, and peridigestive varices support the hypothesis that perforating veins are important in the pathogenesis of esophageal and gastric varices.

Abstract
The prevention of HIV in Women and Infants Demonstration Projects use a conceptual model for maximizing broad community participation for HIV prevention called the Community Mobilization Framework. The projects' comprehensive approach attempts to bring about changes on a community level using a model which encourages community-wide participation of persons with various roles and relationships in the community. The Community Mobilization Framework is one way to systematically conceptualize the organization of the community for the purpose of mobilizing the maximum number of community members around a common health initiative. A community becomes mobilized around an issue by endorsing health-enhancing attitudes, behaviors, and projects supporting positive health outcomes. This mobilization is expressed through the promotion, support, and delivery of motivational and informational health messages which convey consistent ideas, themes, and images. There are two fundamental bases of the Community Mobilization Framework. The first is its characterization of the variety of individual, social, and organizational roles and relationships in the community that might be used in a concerted campaign for HIV prevention for women. The second basis of the model is the description of the nature and extent of the involvement, which includes a continuum of involvement, ranging from simple endorsement to building active coalitions around a health initiative. The paper discusses practical methods of applying these principles, with the Women and Infants Demonstration Projects providing concrete examples.

Abstract
BACKGROUND Pseudomembranous colitis is a rare and serious complication of treatment by antibiotics. The case of a patient with a protracted pseudomembranous colitis followed by two relapses is reported. CASE REPORT A 4 year-old boy was admitted after 18 days of profuse and feverish diarrhea. He had been given amoxycillin for 10 days, one and a half months previously. His temperature was 40 degrees C; he had abdominal pain and leucocytosis was 30,000/mm3. The situation rapidly improved with digestive rest and i.v. antibiotic therapy. Relapse of diarrhea together with bilious vomiting and acute abdominal pains required readmission three days after his discharge. Search for Clostridium difficile in stools remained negative. The diagnosis of pseudomembranous colitis was confirmed by sigmoidoscopy and intestinal biopsy. The patient was given parenteral nutrition for 3 weeks and vancomycin. The disease was complicated by anasarca related to severe protein-loosing enteropathy but evolution was finally favourable after a two month period. CONCLUSION Pseudomembranous colitis remains a serious affection in childhood; its prognosis largely depends on the precocity of diagnosis and treatment.

Abstract
BACKGROUND Sclerotherapy is considered the most effective way to stop bleeding from esophageal varices, but acute variceal bleeding is still associated with a high risk of rebleeding and death. We compared sclerotherapy alone with sclerotherapy and octreotide to control acute variceal bleeding and prevent early rebleeding in patients with cirrhosis. METHODS In a double-blind, prospective trial, 199 patients with cirrhosis and acute variceal bleeding who underwent emergency sclerotherapy were randomly assigned to receive a continuous infusion of octreotide (25 micrograms per hour) or placebo for five days. The primary outcome measure was survival without rebleeding five days after sclerotherapy. RESULTS After five days, the proportion of patients who had survived without rebleeding was higher in the octreotide group (85 of 98 patients, or 87 percent) than in the placebo group (72 of 101, or 71 percent; 95 percent confidence interval for the difference, 4 to 27 percent; P = 0.009). The mean number of units of blood transfused within the first 24 hours after sclerotherapy was lower in the octreotide group (1.2 units; range, 0 to 7) than in the placebo group (2.0 units; range, 0 to 10; P = 0.006). A logistic-regression analysis showed that the treatment assignment (P = 0.003) and the number of blood units transfused before any other treatment was undertaken (P = 0.002) were the only two variables independently associated with survival without rebleeding. After adjustment for base-line differences between the two groups, the odds ratio for treatment failure in the placebo group, as compared with the octreotide group, was 3.3 (95 percent confidence interval, 1.5 to 7.3). The mean (+/- SD) 15-day cumulative survival rate (estimated by the Kaplan-Meier method) was 88 +/- 12 percent in both groups. Side effects were minor, and their incidence was similar in the two groups. CONCLUSIONS In patients with cirrhosis, the combination of sclerotherapy and octreotide is more effective than sclerotherapy alone in controlling acute variceal bleeding, but there is no difference between the overall mortality rates associated with the two approaches to treatment.

Abstract
We conducted a prospective randomized controlled study to evaluate the effectiveness of propranolol and sclerotherapy, compared to a control group, in the prevention of variceal rebleeding in alcoholic cirrhotic patients. Among the 79 patients included, the distribution of patients according to Child-Pugh classification was: A, 22%; B, 40%; and C, 38%. Propranolol was given twice daily with a mean final dose of 54 +/- 16 mg/day, this resulted in a mean reduction in resting heart rate of 26 +/- 7%. Sclerotherapy was performed weekly using 1% polidocanol. End points were rebleeding or death. During the mean follow up of 19 +/- 16 months, 43 patients bled and 22 patients died. The cumulative percentages of patients free of rebleeding at 1 year were: propranolol, 81% (95% confidence interval (CI): 63-92); sclerotherapy, 64% (95% CI: 45-82); control, 54% (95% CI: 36-71); these differences did not reach statistical significance. The cumulative percentages of patients alive at 1 year were: propranolol, 92% (95% CI: 76-98); sclerotherapy, 79% (95% CI: 58-91); control, 81% (95% CI: 60-93); these differences were not statistically significant. Alcohol withdrawal, which occurred in 66% of patients, was an independent predictive factor associated with a decreased risk of rebleeding or death. In conclusion, a life table analysis of patients free of rebleeding, as well as of patients surviving, revealed a tendency in favour of propranolol. The lack of a statistical support for these two favorable effects could be due to poor statistical power.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The aim of the present study is to assess the frequency of pancreas divisum and the features of patients with pancreas divisum in order to assess the role of this anomaly in the occurrence of pancreatitis. A total of 1049 endoscopic retrograde pancreatographies were studied between 1978 and 1988. Patients with pancreas divisum were studied in terms of their clinical findings and their disease (pancreatitis or not). Pancreas divisum was diagnosed in 62 patients (5.9%). No statistical differences with regard to age and sex were found between patients with and without pancreas divisum. The frequency of pancreas divisum was similar in the different groups of disease, especially chronic pancreatitis, acute pancreatitis, recurrent pancreatitis and idiopathic pancreatitis. The study of pancreatograms showed that dorsal ductal abnormalities alone were found as frequently as ventral alterations alone. Our results show that pancreas divisum cannot be directly implicated in the occurrence of pancreatitis, and should not prompt a systematic sphincterotomy of the accessory papilla. This treatment should only be considered in the rare cases of acute recurrent idiopathic pancreatitis with dorsal ductal dilatation and stenosis of the accessory papilla.

Abstract
Two new cases of multiple biliary papillomatosis are reported. In these 2 cases, endoscopic retrograde cholangiography (CRE) was performed; the roentgen findings are described; the mucinous aspect of the bile, the important levels of biliary carcinoembryonic antigen and the intraductal biopsies after endoscopic sphincterotomy (E.S.) furnished precious aid for diagnosis; one E.S. was performed in the two cases allowing satisfactory drainage biliary; in one case, surgery and chemotherapy were associated; based on these two cases and 26 others of literature, management of the disease is discussed.

Abstract
We report a case of mixed tumor of the stomach with a double histological population: carcinoid and adenocarcinoma. The carcinoid component presented an usual morphological pattern with "atypical" elements, and without argyrophilic cells; the carcinoid cells were exclusively marked by an anti-serotonin serum. The other component was a poorly differentiated carcinoma, with muco secretion, which was not marked by and anti-carcino-embryonic antigen serum. The limit between the two components was sharp. The association of mucin in the carcinoma and serotonin in the carcinoid component was an argument in favour of the diagnosis of mixed tumor carcinoid-adenocarcinoma (composite tumor) of the stomach. The evolution after operation leaded to a local recurrence and to the death 10 months later, in spite of chemotherapy. The existence of composite tumors raises nosological, histogenetical and diagnostic problems, which are discussed in this work. The prognosis of these tumors is unknown and therapeutic possibilities seem to be scanty.
