Cleft lip/palate and CDH1/E-cadherin mutations in families with hereditary diffuse gastric cancer.

We report the association of CDH1/E-cadherin mutations with cleft lip, with or without cleft palate (CLP), in two families with hereditary diffuse gastric cancer (HDGC). In each family, the CDH1 mutation was a splicing mutation generating aberrant transcripts with an in-frame deletion, removing the extracellular cadherin repeat domains involved in cell-cell adhesion. Such transcripts might encode mutant proteins with trans-dominant negative effects. We found that CDH1 is highly expressed at 4 and 5 weeks in the frontonasal prominence, and at 6 weeks in the lateral and medial nasal prominences of human embryos, and is therefore expressed during the critical stages of lip and palate development. These findings suggest that alteration of the E-cadherin pathway can contribute to human clefting.

[Treating severe endometriosis by pregnancy: a risky business]. / Traitement de l'endométriose sévère par la grossesse: un pari risqué

We report the case of a young woman presenting with painful deep and rectal endometriosis. This condition had started long ago while the diagnosis had been delayed. Brutal colon occlusion followed the discontinuation of oral contraception. Left colectomy with terminal colostomy was carried out in emergency. The conservative surgical management of deep endometriosis was performed three months later. In women presenting deep endometriosis, the discontinuation of hormonal treatment in order to attempt a spontaneous pregnancy should not be recommended before undertaking a thorough endometriosis and fertility status investigation.

[Laparoscopic surgery of profund endometriosis with rectal affect]. / Chirurgia laparoscopica a endometriozei profunde cu atingere rectala.

OBJECTIVE: To present the principles of laparoscopic treatment for rectal endometriosis and to discuss possible postoperative outcomes. MATERIAL AND METHODS: Our series included women managed for rectal endometriosis during consecutive 20 months in the Department of Gynecology and Obstetrics, Rouen University Hospital, Rouen--France. Patient's characteristics, symptoms, imaging examination results, surgical treatment and postoperative outcomes were all evaluated retrospectively. RESULTS: Sixteen patients presenting with rectal endometriosis were managed surgically, (mean age was 35.9 +/- 6.5 years). All women presented at least one severe painful symptom which was typical of a digestive involvement in 12 cases. MRI results suggested a rectal involvement in 14 cases, and endorectal ultrasound examination clearly showed rectal wall infiltration in all patients. The gynaecological stage of surgical treatment was carried out laparoscopically in 13 cases, and the digestive surgical stage in 7 cases. Two limited and 14 segmental rectal resections were performed. Transitory stoma was carried out in 9 women. The length of the surgical procedure depended on the number of endometriosis localizations with a median value of 6 h 30 min. Postoperative complications occurred in 6 women: 2 anastomosis stenosis, 1 anastomosis fistula, 1 abscess of the parietal wall and 1 bladder atonia. Complains of pain were completely or significantly improved in all cases. CONCLUSION: Surgical treatment for rectal endometriosis may be carried out laparoscopically. It should be reserved for women presenting with severe painful condition and may contribute to significant improvement. However, the balance of benefit and risks must also be assessed on a case to case basis prior to any decision for or against surgical treatment.

Computed tomography-based virtual colonoscopy in the assessment of bowel endometriosis: The surgeon's point of view.

OBJECTIVE: To discuss the role of computed tomography-based virtual colonoscopy (CTC) in preoperative assessment of bowel endometriosis. METHODS: Retrospective study using data prospectively recorded, including 127 patients with colorectal endometriosis, having undergone CTC for bowel endometriosis. The study was conducted in a tertiary referral center during 38 consecutive months. Preoperative assessment included CTC, magnetic resonance imaging (MRI), endorectal ultrasound (ERUS) and clinical examination. Information concerning identification of deep infiltrating endometriosis (DIE) of the bowel, the length and height of colorectal involvement, stenosis of digestive lumen and associated digestive localizations were compared with intraoperative findings. RESULTS: Sensitivity and specificity of CTC for DIE of the rectum, the sigmoid colon, associated digestive localizations, and stenosis of the digestive lumen were respectively 97% and 84%, 93% and 88%, 84% and 97%, 96% and 96%. Intraoperative estimation of the length of digestive tract involved by DIE was closer to that provided by CTC than those provided by MRI and ERUS. When CTC revealed stenosis of digestive lumen, higher rates of colorectal resection (63% vs. 9.6%, < 0.001) and disc excision (25.9% vs. 11%, 0.03) were recorded. DISCUSSION: For those surgeons using various procedures for management of bowel endometriosis, accurate information on the length and height of bowel involvement, as well as the existence of bowel stenosis enables informed decision regarding the feasibility of conservative techniques versus bowel resection. Preoperative identification of associated localizations above the sigmoid colon is another major advantage related to CTC. CONCLUSIONS: CTC provides accurate data on the length and height of colorectal involvement by DIE, stenosis of digestive lumen and associated lesions of digestive tract, which impact on the choice of surgical procedure.

Does percutaneous endoscopic gastrostomy prevent gastro-oesophageal reflux during the enteral feeding of elderly patients?

Percutaneous endoscopic gastrostomy (PEG) is reported to be a safe method for enteral feeding, although its ability to prevent gastro-oesophageal reflux (GOR) during enteral feeding remains controversial. In 12 elderly patients fed enterally to avoid the risk of tracheal aspiration, we have compared two 24-h oesophageal pH profiles, one recorded when enteral feeding was delivered at first via a nasogastric tube (NGT), and the other via a PEG. The second recording was always performed at least 8 days after gastrostomy placement. Enteral nutrition consisted of 500 ml of a polymeric diet delivered 3 times a day at 08:00, 13:00 and 18:00. After gastrostomy placement, enteral feeding was associated with a pathological acid reflux in 8 out of 12 patients. In all of these 8 patients, GOR was mostly related to a high number of reflux episodes. In 4 out of 8 patients, GOR occurred only during the 3 h following the administration of the nutritive diet. In 4 of the patients, GOR did not occur any more after removal of the NGT, whilst gastrostomy placement was followed by GOR in 5 patients. GOR during enteral feeding via PEG is common in elderly subjects. We have shown that a chronological relationship existed in some patients between the endoscopic procedure and the onset of a pathological GOR.

Low levels of glutathione in endoscopic biopsies of patients with Crohn's colitis: the role of malnutrition.

BACKGROUND AND AIMS: During active Crohn's disease, generation of free radicals is increased, and nutritional depletion is frequent. We investigated the glutathione concentration of the colonic mucosa in biopsies from patients with active Crohn's colitis depending on nutritional status. METHODS: Endoscopic biopsies were taken in 10 well-nourished control patients, and 18 patients with active Crohn's disease (11 well-nourished, seven malnourished with a recent weight loss > 10 %). Colonic biopsies were taken from healthy and inflamed mucosa and analysed for total glutathione concentration. RESULTS: Mucosal glutathione concentration (nmol/mg wet tissue) was lower in patients with active colitis both in diseased and healthy mucosa as compared with controls (1.89 +/- 0.39, 2.08 +/- 0.4 and 6.69 +/- 4. 94, respectively, P< 0.05). Mucosal glutathione was lower in healthy mucosa from malnourished versus well-nourished patients: 1.8 +/- 0.2 vs 2.3 +/- 0.37 (P= 0.02). CONCLUSIONS: Mucosal glutathione is markedly lower in active Crohn's colitis, even in healthy mucosa; glutathione depletion tends to be more severe in malnourished patients. Glutathione depletion may be related in part to malnutrition and contribute to a prolonged evolution of disease and could be a target for pharmacological and nutritional support.

Which patients taking non-aspirin non-steroidal anti-inflammatory drugs bleed? A case-control study.

OBJECTIVE: To identify risk factors for gastrointestinal bleeding (GIB) among users of non-aspirin, non-steroidal anti-inflammatory drugs (NANSAIDs). DESIGN: Case-control study. PARTICIPANTS: A total of 120 patients aged over 60 years and using NANSAIDs were hospitalized between January 1988 and September 1992 for GIB related to erosions or ulceration of the gastroduodenal mucosa. A group of 100 general practitioners selected two controls matched for age and sex, receiving NANSAIDs and without GIB, for each patient. METHODS: The same questionnaire was used to interview patients and controls about their medical history, use of NANSAIDs and other drugs, alcohol and tobacco use, recent stress and nutritional status. RESULTS: The adjusted odds ratios (OR) for the risk factors related to the pattern of NANSAID use were 3.39 [95% confidence interval (CI) 1.77-6.47] when the intake of NANSAIDs was followed by decubitus, 3.00 (95% CI 1.54-5.85) when NANSAIDs were taken before a meal, 6.05 (95% CI 2.10 17.43) with a high dose of NANSAIDs, 5.87 (95% CI 2.00-17.25) with recent NANSAID use, 3.35 (95% CI 1.47-7.64) with NANSAIDs associated with aspirin use, 3.46 (95% CI 1.15-10.36) with more than one NANSAID, and 10.70 (95% CI 1.06-108.07) when NANSAIDs were associated with corticosteroids. The patient-related risk factors and their OR were 9.94 (95% CI 3.29-24.28) for irregular food intake, 3.94 (95% CI 1.45-10.69) for previous peptic ulcer, 3.71 (95% CI 1.26-10.89) for recent weight loss, 4.44 (95% CI 1.48-13.30) for heavy alcohol abuse, 2.92 (95% CI 1.36-6.26) for recent stress and 5.26 (95% CI 1.19-23.33) for a past history of GIB. CONCLUSION: This study identified a group at 'high risk' for GIB which would benefit from the development of a prophylactic therapy.

Low levels of gastric mucosal glutathione during upper gastric bleeding associated with the use of nonsteroidal anti-inflammatory drugs.

OBJECTIVES: To investigate the glutathione concentrations in gastric mucosa from patients with acute gastric bleeding related to nonsteroidal anti-inflammatory drugs (NSAIDs), and to test the influence of nutritional status on mucosal glutathione. Glutathione protects the gastrointestinal mucosa against reactive oxygen species, and glutathione content in various tissues may be depleted during malnutrition. METHODS: Endoscopic biopsies were obtained from 39 patients. Eighteen of these (9 well-nourished, 9 malnourished) presented with gastric bleeding ulcers related to NSAIDs. Twenty-one other patients (12 well-nourished, 9 malnourished) underwent normal routine diagnostic endoscopy and served as controls. Malnutrition was defined as a loss of over 10% of normal body weight and/or plasma albumin levels below 30 g/l. Gastric biopsies were taken from the fundus and antrum (controls) and from the region of the ulcer (patients with acute bleeding) and frozen quickly until glutathione analysis by high-performance liquid chromatography (HPLC) coulometric detection. Results were expressed as nmol/mg wet tissue. RESULTS: Gastric mucosal glutathione levels were significantly (P < 0.05) lower in both the antrum (0.81 +/- 0.34 v. 1.41 +/- 0.88 nmol/mg tissue) and the fundus (1.04 +/- 0.54 v. 1.43 +/- 0.92 nmol/mg tissue, P < 0.05) in malnourished than in well-nourished control patients. Glutathione mucosal concentrations were decreased significantly in patients with NSAID-induced gastric bleeding compared with control patients (0.38 +/- 0.36 v. 1.12 +/- 0.56 nmol/mg tissue, P < 0.001), and the lowest glutathione levels were observed in malnourished patients (0.28 +/- 0.20 v. 0.48 +/- 0.15 nmol/mg tissue in well-nourished patients, not significant). CONCLUSION: Malnutrition is associated with low levels of gastric glutathione. This may contribute to the severity and the onset of haemorrhage in NSAID-induced gastric ulcers.

Epidemiology and course of acute upper gastro-intestinal haemorrhage in four French geographical areas.

OBJECTIVE: To compare incidence rates and epidemiological characteristics of acute upper gastrointestinal haemorrhage (AUGIH) in France with those of other European studies. DESIGN: Population-based multi-centre prospective survey. SETTING: 29 public hospitals and 96 private specialists in gastroenterology in four administrative areas in France during 1996. SUBJECTS: A total of 2133 AUGIH patients 18 years and over were included in the six-month study. OUTCOME MEASURES: Incidence and mortality. RESULTS: The overall incidence in France was 143 cases per 100000 persons per year, classified as out-patients (16%), emergency admissions (59%) and in-patients (25%). The incidence rates increased with age except for in-patients, and were higher in males. Peptic ulcer (36.6%), varices (13.7%) and erosive disease (12.3%) were the most frequent diagnoses. In 677 patients (31.7%), aspirin, antiinflammatory drugs or corticosteroids were taken on the 7 days before bleeding. The overall mortality (out-patients excluded) was 14.3% (10.7% for emergency patients and 23% for in-patients). Mortality was associated with comorbidities (especially malignancies, cirrhosis, asthma or respiratory deficiency), was lower in emergency patients using non-steroid anti-inflammatory drugs, and higher in in-patients using corticosteroids. CONCLUSIONS: In France, patients with AUGIH are frequently managed as out-patients. Gastrotoxic drug use is frequently associated with AUGIH and constitutes a strategic opportunity for preventive treatment. Discrepancies between countries are not clearly explained either by demographic factors or by drug use, but this may be related to the emphasis on AUGIH in in-patients.

[Upper digestive hemorrhage in patients over 80 years of age: incidence and prognostic factors]. / Hémorragies digestives hautes du sujet âgé de plus de 80 ans: fréquence et facteurs pronostiques.

OBJECTIVES: The aim of this study was to assess the incidence and the prognosis of upper gastrointestinal hemorrhage in patients aged over 80 years. METHODS: Between January and December 1993, among 360 patients admitted for upper gastrointestinal hemorrhage, 63 were older than 80 years (18%). Data were prospectively collected in all patients. RESULTS: Before admission, 8 experienced a lipothymia and 3 a shock. The median initial hematocrit was 29%. Endoscopy was performed in 59 patients and a cause was determined in 49 (83%). The main cause of bleeding was gastric and duodenal ulcer (n = 26, 53%) and ten of them were graded Forrest < or = IIb. Endoscopy did not contribute in 10 patients and was impossible in 4 because of an hemodynamic failure. Gastrotoxic drugs intake was found in 28 patients: non steroidal anti-inflammatory drugs (n = 14) and aspirin (n = 14). Endoscopic injection therapy was performed in the 10 patients with gastric or duodenal ulcer < or = Forrest IIb and permanent hemostasis was achieved in 8 out of 10. No further bleeding was seen in 53 patients (84%), while bleeding persisted in 4 and rebleeding occurred in 6 (9.5%) (3 duodenal ulcers, 2 gastric carcinomas and 1 esophageal varices bleeding). Only one patient required emergency surgery (rebleeding duodenal ulcer). The overall mortality was 12/63 (19%):50% of the deaths were related to hemorrhagic complications and 50% to concomitant disease. Only one patient among those taking gastrotoxic drug died from bleeding. The risk factors of death from bleeding were: initial shock (P = 0.02), lipothymia before admission (P = 0.02), rebleeding (P < 0.01), persistence of bleeding (P < 10(-4)). Gastrotoxic drugs intake was associated with a favorable prognosis (P < 0.05). The prognosis was not significantly affected by an initial hematocrit < 30% or blood units transfused > or = 4. CONCLUSIONS: People older than 80 years account for a large proportion of upper gastrointestinal bleeding (18%). The more common cause is gastric or duodenal ulcer. Mortality in these patients is high (19%). An initial shock or lipothymia, rebleeding or persistence of bleeding worsens prognosis. Gastrotoxic drugs intake is frequent (44%), but is associated with a good prognosis.

[Prospective evaluation of three kits for endoscopic percutaneous gastrostomy (PEG)]. / Evaluation prospective de trois kits de gastrostomie percutanée endoscopique (GPE).

OBJECTIVES: Percutaneous endoscopic gastrostomy (PEG) is often used for long-term enteral feeding. Various PEG kits are currently available. A technical evaluation could be useful in providing a criteria of choice between the different kits. METHODS: Therefore, from January 1995 to January 1998, we prospectively performed a short- and a mid-term technical evaluation of 150 PEG kits: 106 Compat Sandoz, 37 Flocare Nutricia et 7 Sherwood. RESULTS: In 20% of the patients studied, technical problems during endoscopic insertion of the probe were observed. Only minor incidents were found for Compat Sandoz and Flocare Nutricia kits. However, major problems occurred with the Sherwood kits leading to a very difficult (4 cases) or impossible (2 cases) transcutaneous introduction of the catheter into the stomach. Mid-term outcome was evaluated in 86 of the 150 patients (57%) with a median follow-up duration of 5 months (range: 1-24). The main finding of the mid-term evaluation was a significant alteration of the Compat Sandoz tube. CONCLUSION: This prospective evaluation shows that technical improvement of the available PEG kits are needed, that the PEG polyurethane tube could be preferred for long-term enteral feeding.

[Compared efficiency of three strategies of management of chronic hepatitis C. Effect on the risk of cirrhosis 8 years after diagnosis]. / Efficience comparée de trois stratégies de prise en charge de l'hépatite chronique C. Influence sur le risque de cirrhose à 8 ans.

OBJECTIVES AND METHODS: The goal of treating chronic hepatitis C with alfa interferon is to eradicate HCV infection. The actual influence of this treatment on the development of cirrhosis is unknown. Moreover, the poor results and the high cost of this treatment have caused a public health problem. Three strategies were evaluated by decision analysis: no treatment (S1), treatment of chronic active hepatitis only (S2), treatment of all chronic hepatitis (S3). For each strategy, we estimated the probability of the occurrence of the following events based on data in the literature: presence of chronic active hepatitis, chronic persistent hepatitis or cirrhosis at the time of diagnosis; discontinuation of interferon because of adverse events; biological response to treatment; incidence of cirrhosis 8 years after diagnosis without treatment or in case of response to treatment. RESULTS: The risk of cirrhosis was 28.5% with S1, 25.4% with S2, and 25.2% with S3, 8 years after diagnosis. If HCV infection was detected early before cirrhosis, the number of cases of cirrhosis occurring in an 8 year-followup period would be 45,600 with S1, 40,640 with S2, and 40,320 with S3 and the cost of S2 and S3 would be 1.23 10(9) French Francs (FF), and 2.57 10(9) FF, respectively. The mean cost to prevent one case of cirrhosis would vary from 248,000 FF with S2 to 487,000 FF with S3. CONCLUSION: This decision analysis study suggests that the S3 strategy is not suitable for a population of HCV infected patients, because of its low efficiency and high cost.

[Management of upper digestive hemorrhage occurring in the community: patterns of patient care in 4 French administrative areas]. / Prise en charge des hémorragies digestives hautes communautaires. Trajectoires des malades dans 4 départements français.

AIMS: To describe patterns of health care management in patients with upper gastrointestinal hemorrhage and to identify factors linked to the different patterns. PATIENTS AND METHODS: We conducted a prospective study of patients over 18 with upper gastrointestinal hemorrhage (inpatients excluded) among all public hospitals and private practice gastroenterologists in 4 French administrative areas (3 in Northern France and one in the South West). RESULTS: One thousand six hundred and two patients were included over a six-month period (1996). An endoscopic procedure was performed in 1532 patients in public (70%) or private (20.5%) hospitals, or at private office (9.5%). Hospitalization was necessary in 78.8% of the patients in university, non university public or private hospitals (38.9, 45.5 and 15.6%, respectively) with a median duration of 6.5 days. Admission was associated to old age, short delay between hemorrhage and endoscopic procedure, previous gastrointestinal bleeding, cirrhosis or cancer, bleeding from peptic ulcer or esogastric varices. Endoscopic hemostasis was performed in 21.4% of the patients, more often in university and no university public hospitals. Surgery was necessary in 4% of the patients. Death rate was 10.7%. Important geographical variations were observed concerning referral patterns. Patients' characteristics did not differ between the 4 areas. On the other hand, health care supply provided in the management of upper gastrointestinal hemorrhage was different in the four French geographical areas. CONCLUSION: a) An initial endoscopic procedure is nearly always performed in patients with an upper gastrointestinal hemorrhage in France; in 1 patient out of 10, endoscopy was performed in a private gastroenterologist office; b) hospital admission was strongly related to epidemiological and clinical criteria of severity; c) the geographical variations observed in referral patterns depend in part on health care supply; d) upper gastrointestinal haemorrhage status could be used as an indicator of the quality of health care organizations.

[Photodynamic therapy by coloring laser. Can it represent a therapeutic alternative for small epidermoid cancers of the esophagus?]. / La photothérapie dynamique par laser à colorant. Peut-elle représenter une alternative thérapeutique pour les petits cancers épidermoïdes de l'oesophage?

Our aim was to assess the efficacy of photodynamic therapy in inoperable patients with small esophageal carcinoma. Eleven patients were treated for squamous cell carcinomas ranging in size from 1 to 3 cm2. Hematoporphyrin (between 3 and 5 mg/kg) was injected intravenously and then the tumor irradiated at endoscopy 72 hours later with a dye laser (630 nm) at an energy of 250 joules/cm2. Complete destruction of the lesion was obtained in 6 cases with negative biopsies at 1 month. In all 6 patients, no recurrence was seen after a median follow-up of 4 months (range: 2-38). Partial destruction of the tumor was obtained in 4 cases while treatment was a complete failure in the last patient. Two instances of mild cutaneous photosensitization occurred. Two patients treated for recurrence after radiotherapy, died of esophageal perforation directly related to the procedure. Photodynamic therapy appears to be a possible effective treatment for esophageal squamous cell carcinoma in inoperable patients when other curative treatment modalities are not possible.

[Neuroma of the common bile duct: a rare cause of jaundice]. / Névrome de la voie biliaire principale: une cause rare d'ictère.

We report a case of neuroma of the main bile duct arising twenty years after cholecystectomy. The patient, a 82-year-old woman, was admitted for jaundice. Endoscopic retrograde cholangiography showed a regular stenosis of the main bile duct. Histologic examination demonstrated neuroma. Based on the analysis of this and 15 other previously published cases, the following features of bile duct neuroma were outlined: a) variable interval between cholecystectomy and the onset of jaundice (6 months to 35 years); b) the generally complicated postoperative course, c) the various localizations on the biliary tree (cystic, main bile duct, intrahepatic bile duct) and, d) the circumstances of onset.

[Expandable metal stents in palliative treatment of malignant colorectal stricture. A report of 17 consecutive patients]. / Les prothèses métalliques expansives dans le traitement palliatif des sténoses malignes colo-rectales.

OBJECTIVE: Several endoscopic procedures have been used to avoid a colostomy in palliative treatment of occlusive colorectal cancer. The aim of this study was to evaluate in intent to treat the long term effectiveness and safety of self-expanding metal stents as a palliative treatment in patients with neoplastic colonic obstruction. PATIENTS AND METHODS: From December 1997 to June 2000, seventeen patients were treated with 21 colonic stents. Sites of obstruction were high rectum in 3, sigmoid in 11 and left colon in 3. RESULTS: Stent placement was successful in 16/17 patients (94%). Relief of bowel obstruction occurred in 13 patients (74%) in the first 48 hours. Expandable metal stent achieved an effective bowel transit until death in 9 of the 17 patients (53%). Clinical complications occurred in 6 patients (35%): 2 perforations, 2 migrations, 1 rectal bleeding and 1 dislocation of the stent. Subsequent colostomy was done in 5 patients. CONCLUSION: Colonic stenting is an alternative palliative treatment in malignant colorectal stricture. However, morbidity and need for subsequent colostomy should be taken into account.

[Upper gastrointestinal bleeding in patients treated by low-dose aspirin]. / Hémorragies digestives hautes et aspirine à faible dose.

AIM OF THE STUDY: To estimate the number of people treated by low-dose aspirin (<330 mg daily) in France and to evaluate the risk of upper gastrointestinal bleeding associated with low-dose aspirin treatment. SUBJECTS AND METHODS: One thousand six hundred and two patients with upper gastrointestinal bleeding were included between January and June 1996 in 4 French areas. Data about patients characteristics, drugs recently used, and bleeding lesions were prospectively collected. Five hundred seventy five cases were matched for sex, age and area with control people without previous upper gastrointestinal bleeding. Low-dose aspirin intake in the population was estimated from the control group. Aspirin intake in the previous 7 days in cases and in controls was compared by logistic regression, adjusted for other gastrotoxic drugs intake. RESULTS: Low-dose aspirin is taken by about 1.2 millions adults in France. In 1 602 patients, gastrointestinal bleeding was related to a peptic ulcer in 34%. Aspirin was associated with higher risk of upper gastrointestinal bleeding: OR=1.68 (1.03-2.74) with low-dose, and OR 1.42 (0.91-2.21) with higher doses. CONCLUSION: About 2.8% of the population is exposed to low-dose aspirin in France. This treatment seems to be associated with a high risk of upper gastrointestinal bleeding.

[Should watermelon stomach be considered to be an unrecognized localization of scleroderma?]. / Doit-on considérer l'estomac pastèque comme une localisation méconnue de la sclérodermie?

We reported a typical case of watermelon stomach which occurred during the course of a limited cutaneous systemic sclerosis. Watermelon stomach is an important source of upper gastrointestinal bleeding which requires endoscopic treatment. Such an association has already been described and we suggest that watermelon stomach could be an unrecognized localization of scleroderma stomach involvement. Because gut involvement may precede skin manifestations. A search of progressive systemic sclerosis should be done with clinical examination, antinuclear antibodies research (especially anticentromere antibodies) and nailfold capillaroscopy when a such endoscopic appearance is noted.

[Digestive complications of aspirin]. / Complications digestives de l'aspirine.

INTRODUCTION: This review focuses on aspirin-related gastrointestinal side-effects and the mechanism by which aspirin causes gastrointestinal damage. CURRENT KNOWLEDGE AND KEY POINTS: Aspirin causes direct gastric damage by topical irritant effects and indirect damage via systemic inhibition of cyclooxygenase synthesis and microcirculation injury. The question of a possible synergistic relation between the presence of Helicobacter pylori infection and aspirin use on gastric damage is not resolved. The pathogenesis of small intestinal and colonic damage is less well understood; an increase in intestinal permeability and free radical synthesis are suggested. Gastric damage predominates. Gastroduodenal lesions from aspirin have been documented in endoscopy studies. The lesions occur rapidly, even for low-dose aspirin. The association of aspirin consumption with upper gastrointestinal bleeding has been well established. The main risk factors are advanced age, concomitant use of nonsteroidal antiinflammatory drugs and history of ulcer. Low-dose aspirin are associated with increased risk of gastrointestinal bleeding and this risk is dose-dependant. Chronic aspirin consumption can cause iron deficiency anaemia. Uncomplicated gastric ulcer (but not uncomplicated duodenal ulcer) is associated with aspirin use, with relative risk 3. Other upper gastrointestinal complications have been reported: stenosis and perforation. Aspirin can also damage other areas of the gastrointestinal tract. Oesophageal injuries (oesophagitis and stricture) have been reported. Aspirin is associated with variceal bleeding episodes in patients with cirrhosis. The adverse effects of aspirin on the small bowel are perforation, bleeding, increasing permeability. The adverse effects of aspirin on the large intestine are perforation, bleeding, collagenous colitis and anorectal stenosis with suppositories containing aspirin. Direct clinical data regarding prophylaxis with co-administration of a protective drug are not yet available for aspirin. FUTURE PROSPECTS AND PROJECTS: Patients should be made aware of adverse gastrointestinal effects due to aspirin. Further studies regarding prophylactic therapy of low-dose aspirin induced gastroduodenal lesions, which identify a subset of patients who may be at higher risk than the low-dose aspirin population as a whole, are warranted.

[Hemorrhaging eso-gastro-duodenal ulcers: epidemiology and management. A multicenter prospective study]. / Les ulcères oeso-gastro-duodénaux hémorragiques: épidémiologie et prise en charge. Etude prospective multicentrique.

UNLABELLED: The aim of this study was to estimate the incidence, and to describe the characteristics and medical care in patients with bleeding upper gastrointestinal ulcers in the general population. PATIENTS AND METHODS: A study was performed over six months in 1996 in 4 French geographical areas: Finistère, Gironde, Seine-Maritime, and the Somme (3 million people minimum 18 years). All public or private hospitals, and specialist gastroenterologists in private practice participated in the study, based on a standardized questionnaire. RESULTS: Over 6 months 793 patients with bleeding ulcers were identified, corresponding to 27 per 100,000 inh./year or 24,000 cases in France. Most patients were men (60%) and 40.1% were 75 years and older. The ulcer was oesophageal (6%), gastric (47%), or duodenal (69%). In 406 patients (51.2%) a chronic disease was present (cancer, cirrhosis, circulatory, respiratory or cardiac disease). In 237 cases (29.9%) the ulcer occurred in patients, 453 patients (57.1%) were admitted and 103 patients (13%) were managed as outpatients. Gastrotoxic drugs were taken by 349 patients (44%): non steroidal anti-inflammatory drugs (18.7%), aspirin (21.2%, including 2/3 with doses under 330 mg/day), corticosteroids (7.8%) and 24.3% had anticoagulant therapy. Patients were managed in university hospitals (39.3%), other public or non profit hospitals (44.2%) or private hospital (16.5%) with geographical differences between the 4 areas. Therapeutic endoscopy was performed in 16.9% and a surgical procedure was performed in 5.9%. The mortality rate (outpatients excluded) was 13.5% (n = 93), but only 2% (n = 16) of death were associated with a bleeding ulcer: mortality was higher in inpatients (24.1%) than in out patients (8.1%). A chronic disease was also associated with higher mortality (17.9% versus 8.1%). CONCLUSION: Bleeding ulcers are frequent and severe, especially in inpatients or associated with chronic conditions. A gastrotoxic drug used is found in about fifty percent of the cases.
