[Simultaneous detection of IgM anti-Epstein-Barr virus and IgM anti-hepatitis A during an acute hepatitis]. / Détection simultanée d'IgM anti-Epstein-Barr virus et d'IgM anti-hépatite A lors d'une hépatite aiguë.

We report a case of a 15-year-old young man who was admitted for an acute hepatitis. Virological assessment showed both IgM anti-EBV and IgM anti-hepatitis A. IgG anti-EBNA and clinical history allowed to rule out the hypothesis of a recent EBV infection and confirmed the diagnosis of acute hepatitis A infection.

Meta-analysis: evaluation of adjuvant therapy after curative liver resection for hepatocellular carcinoma.

AIM: To evaluate adjuvant modalities after curative resection for hepatocellular carcinoma using a meta-analysis of randomized and non-randomized controlled trials. METHODS: In a first step, a meta-analysis of randomized controlled trials was carried out. Sensitivity analyses after inclusion of non-randomized controlled trials were performed. Four therapeutic modalities were evaluated: pre-operative transarterial chemotherapy, post-operative transarterial chemotherapy, systemic chemotherapy and a combination of systemic and transarterial chemotherapy. RESULTS: Only post-operative transarterial chemotherapy improved survival significantly at 2 years [difference, 22.8%; confidence interval (CI), 8.6-36.9%; P = 0.002] and 3 years (difference, 27.6%; CI, 8.2-47.1%; P = 0.005), and decreased the probability of no recurrence at 1 year (difference, 28.8%; CI, 16.7-40.8%; P < 0.001), 2 years (difference, 27.6%; CI, 8.2-47.1%; P = 0.005) and 3 years (difference, 28%; CI, 8.2-47.9%; P = 0.006). In a sensitivity analysis after inclusion of non-randomized controlled trials, post-operative transarterial chemotherapy still improved survival at 1 year (difference, 9.6%; CI, 0.8-18.3%; P = 0.03), 2 years (difference, 13.5%; CI, 0.9-26%, P = 0.04) and 3 years (difference, 18%; CI, 7-28.9%; P < 0.001), and decreased the probability of no recurrence at 1 year (difference, 20.3%; CI, 7.7-33%; P = 0.002), 2 years (difference, 35%; CI, 21.4-46.3%; P < 0.001) and 3 years (difference, 34.5%; CI, 18.7-50.3%; P < 0.001). CONCLUSION: Post-operative transarterial chemotherapy improved survival and decreased the cumulative probability of no recurrence. New randomized controlled trials evaluating this modality are required.

Evidence of lymphocyte alveolitis in Crohn's disease.

Cellular characteristics of bronchoalveolar lavage (BAL) were investigated in 18 consecutive patients with Crohn's disease, who were free of clinical pulmonary symptoms and had normal findings on chest roentgenograms. Total BAL cell count and cellular viability of alveolar macrophages did not differ significantly between patients and control subjects. Percentage of alveolar lymphocytes was increased in 11 of 18 patients (from 18 percent to 79 percent). There was no apparent correlation between BAL differential cell count and abnormal pulmonary function tests noted in 11 patients, drug treatment or Crohn's disease site, and activity. These results demonstrate a high proportion of latent lymphocyte alveolitis as assessed by BAL, suggesting a latent involvement of the lung in Crohn's disease.

Noninvasive imaging of insulinomas and gastrinomas with endoscopic ultrasonography and somatostatin receptor scintigraphy.

BACKGROUND: Classic morphological techniques are of limited value for imaging endocrine duodenopancreatic tumors, and invasive procedures such as intraarterial stimulation are often used. Two noninvasive procedures, endoscopic ultrasonography (EUS) and somatostatin receptor scintigraphy (SRS), were recently described with promising results. METHODS: In this study we correlated the results of preoperative EUS (n = 34) and SRS (n = 30) with operative findings in patients with histologically proven insulinoma (n = 20) or gastrinoma (n = 21). RESULTS: The sensitivity and positive predictive value (PPV) of EUS were respectively 77% and 94% for pancreatic tumors (insulinomas and gastrinomas), 40% and 100% for duodenal gastrinomas, and 58% and 78% for metastatic lymph nodes. The sensitivity and PPV of SRS for insulinoma were 60% and 100%, respectively. In patients with gastrinoma, the sensitivity and PPV of SRS were respectively 25% and 100% for pancreatic gastrinomas, 72% and 100% for duodenal gastrinomas or periduodenal metastatic lymph nodes, and 67% and 80% for liver metastasis. In patients with multiple endocrine neoplasia, neither one of the two techniques detected all tumors. Overall sensitivity of combined EUS and SRS was 89% for insulinoma (n = 9) and 93% for gastrinoma (n = 14). CONCLUSIONS: EUS and SRS for gastrinomas and insulinomas should be considered as the initial preoperative imaging procedures and may render invasive procedures unnecessary for most patients.

Chronic pancreatitis: a complication of sarcoidosis?

Gastrointestinal localizations of sarcoidosis are rare. A total of 14 cases of pancreatic involvement in sarcoidosis has been reported previously. We report here a case of late onset idiopathic chronic pancreatitis diagnosed at the same time as sarcoidosis with liver, colonic, renal, mediastinal and neurologic involvement in a 56-year-old man. This case further suggests a possible relationship between idiopathic chronic pancreatitis and multisystem diseases.

Interferon alpha therapy in haemophilic patients with chronic hepatitis C: a French multicentre pilot study of 58 patients.

BACKGROUND AND OBJECTIVES: Information about the long-term efficacy of interferon alpha (interferon-alpha) in haemophilic patients with chronic hepatitis not co-infected with the human immunodeficiency virus (HIV-1) is still limited. Previous studies seemed to indicate a low rate of response. The aim of this study was to evaluate the safety and long-term efficacy of interferon treatment in multi-transfused haemophiliacs. METHODS: Fifty-eight haemophiliacs were scheduled to receive 3 MU of interferon-alpha 2b three times a week for 12 months. The patients were followed up for at least 24 months post-treatment. Response was assessed by measurements of serum hepatitis C virus (HCV) RNA. RESULTS: Twenty-four patients (41.4%) dropped out. Except for seven patients, the symptoms that led to interrupting interferon treatment would probably not have resulted in the same decision in non-haemophilic patients. One patient developed an inhibitor to the deficient clotting factor without haemorrhagic consequences. In an intent to treat, the sustained virological response rate was 14%. However, when considering only the 34 patients who received the full treatment, HCV-RNA was cleared in eight patients (23%). CONCLUSIONS: This study suggests that multi-transfused haemophiliacs with chronic hepatitis not co-infected with HIV-1 respond to prolonged treatment with interferon-alpha in a similar proportion to that observed in non-haemophiliacs. There was a high rate of patients who did not complete the interferon-alpha treatment, and this seems to be characteristic of this patient population.

[Comparative effectiveness of ranitidine (150 mg X 2) and cimetidine (400 mg x 2) in the treatment of acute duodenal ulcer. A French multicenter controlled clinical trial]. / Efficacité comparée de la ranitidine (150 mg X 2) et de la cimétidine (400 mg X 2) dans le traitement de l'ulcère duodénal en poussée. Essai thérapeutique contrôlé multicentrique français.

In a single-blind multicenter trial, 444 patients with duodenal ulcer (DU) proven by endoscopy were randomly assigned to treatment with either ranitidine, 150 mg, or cimetidine, 400 mg, morning and evening. Clinical assessments were carried out at 2 and 4 weeks and endoscopy at 4 weeks. The patients in the 2 groups were comparable. Cumulative healing rates at 4 weeks were 78.3 p. 100 in the ranitidine group (n = 226) and 65.6 p. 100 in the cimetidine group (n = 218) (p less than 0.003). Pain at the start was of similar severity in both groups, and disappeared at the same rate under ranitidine or cimetidine: 64 p. 100 patients were painless at 1 week, 80 p. 100 at 2 weeks and 88 p. 100 at 4 weeks. Thirty-eight patients complained of mild side effects: 22 on ranitidine (2 trial withdrawals) and 16 on cimetidine (1 trial withdrawal). Multifactorial analysis (logistic model) revealed that linear ulcers had a lower healing probability than round ulcers (p less than 0.002) whatever the treatment group (cimetidine: 47 p. 100 vs 68 p. 100, ranitidine 57 p. 100 vs 80 p. 100 respectively). Smoking habits (p less than 0.057) and age less than 40 years (p = 0.056) did not significantly influence healing rates, although smokers and younger patients under cimetidine had the lowest healing rate. Thus, at the dosage used in our trial, ranitidine is more efficient for healing DU at 4 weeks than cimetidine but not for pain relief.(ABSTRACT TRUNCATED AT 250 WORDS)

[Intestinal surgery in the treatment of stenoses of the small intestine in Crohn disease]. / Les plasties intestinales dans le traitement des sténoses de l'intestin grêle au cours de la maladie de Crohn.

Strictureplasty is an alternative to extensive and/or multiple small bowel resections in the surgical treatment of Crohn's disease. We here report a series of 22 patients (12 M-10 F--mean age years: 28). All patients had a non-perforative form of Crohn's disease lasting for a mean of 8 years. Nine out of 22 had had previous intestinal resection. A total of 201 stenosis was identified during peroperative examination (mean per patient: 9). Only tight stenoses (diameter < 2 cms) were treated while others were left untouched (n = 22 in 11 patients). Eighty-three stenoses were treated by short strictureplasty and 24 by long strictureplasty using steel thread. One or several resections were simultaneously performed in 15 patients. Mortality was nil. A post operative abscess without loosened suture was drained. The mean follow-up in the 22 patients was 24 months (3-7 years). Clinical and radiological symptoms of stenosis were relieved after strictureplasty. Clinical recurrence occurred in 5 patients among 12 followed-up more than 2 years. Subsequent surgery was required in 4: in one case hemorrhagic ulceration developed within a long strictureplasty and in 3 others stenosis developed in plasty areas but also in previously healthy areas. In conclusion, strictureplasty is a short and long-term efficient procedure in the treatment of Crohn's disease stenosis. It allows limiting extensive intestinal resection. A more prolonged follow-up is needed in order to evaluate the rate of long-term recurrence and complications that would limit the interest of this technique.

[Palliative treatment of cancer of the esophagus and cardia by laser photo-ablation]. / Traitement palliatif des cancers de l'oesophage et du cardia par photoablation laser.

The results of the palliative treatment by laser photo-ablation for esophageal and gastric cancers in 79 nonsurgical patients are reported. The aim of treatment was to relieve dysphagia in 60 patients with an obstructive tumor, to maintain esophageal lumen patency in 8 patients with a nonobstructive tumor, and to completely destroy 11 small tumors. The success rate in the patients with dysphagia was 78 p. 100. Functional improvement lasted as long as patients survived with further treatment required once or twice a month. The best results were obtained in exophytic, non circumferential lesions, and in adenocarcinomas of the esophagogastric junction. The localization at the upper third of the esophagus was associated with poor prognosis. The complication rate was 6.6 p. 100. Eight of the 11 small lesions were completely destroyed, but radiation therapy had been associated in four cases with invasive cancer, one of which recurred after 6 months. No complications occurred in this last group of patients.

[Hepatic calcifications revealing epithelioid hemangioendothelioma]. / Calcifications hépatiques révélatrices d'un hémangioendothéliome épithélioïde.

This report concerns a case of hepatic epithelioid hemangioendothelioma presenting with liver enlargement, multiple hepatic calcifications on the plain abdominal film and bilateral interstitial pneumonia. Epithelioid hemangioendothelioma is an unusual soft tissue tumor of "intermediate malignancy" characterized by a multicentric involvement of the liver and originating from endothelial cells. Histopathologic diagnosis may be difficult because of possible confusion with sclerosing epithelial tumors.

Idiopathic acute pancreatitis and sarcoidosis.

Pancreatic involvement is rare in sarcoidosis. We describe a 30-year-old man who had two episodes of acute pancreatitis within one month with no current aetiology. Diagnosis of sarcoidosis was based on the presence of bilateral mediastinal adenopathies, alveolar lymphocytosis on bronchoalveolar lavage and biopsy of an enlarged lymph node showing multiple granulomas. This case and five others previously reported in the literature suggest the diagnosis of sarcoidosis should be considered in apparently acute idiopathic pancreatitis.

[Percutaneous drainage of a presacral and spinal extra-dural abscess complicating Crohn's disease]. / Drainage percutané d'un abcès présacré et rachidien extra-dural compliquant une maladie de Crohn.

A 43-year-old man with Crohn's disease was hospitalized because of bilateral radicular pain secondary to a presacral abscess penetrating into the extra-dural space from L5 to S3. Conservative treatment using computed tomography guided percutaneous drainage of the abscess and parenteral antibiotherapy allowed complete recovery.

[Crohn disease. Results of surgical treatment]. / Maladie de Crohn - résultats du traitement chirurgical.

The aim of this study was to describe and to analyze the results of surgery for Crohn's disease in a retrospective series of 155 operations performed in 124 patients from 1949 to 1981 by the same surgical team. Indications for surgical treatment were as follows: acute complications (25 p. 100), intestinal obstruction (35 p. 100), systemic inflammatory manifestations (40 p. 100). Three patients died postoperatively and complications necessitated a reintervention in 10 other subjects. Surgical indications and late postoperative prognosis were significantly different in patients with right-sided bowel lesions (i. e. terminal ileitis, ileocolitis of the ascending colon) and in those with left colonic involvement (i.e. colitis of the whole or descending colon, rectitis and anoperineal lesions). Surgery was required because of failure of medical treatment in 73 p. 100 of Crohn's disease affecting the left colon and in 17 p. 100 of the right-sided lesions (p less than 0.001). After resection a recurrence rate after 1 year and 3 years of respectively 50 and 62 p. 100 was observed in the left colonic disease group and in 5 and 23 p. 100 of the cases respecting the left colon. Finally 31 reoperations were necessary; no surgical mortality occurred in 12 patients with right-sided lesions whereas 5 among 19 patients with involvement of the left colon died postoperatively. These results: a) confirm the high postoperative rate of recurrence (or relapse) after surgical bowel resection for Crohn's disease (especially when the left colon is affected), b) emphasize the need for the surgeon to be very cautious when determining the extent of resection.

[Esophageal cancer and endoscopic sclerosis of esophageal varices: a fortuitous association?]. / Cancer oesophagien et sclérose endoscopique des varices oesophagiennes: une association forfuite?

We report the case of 4 male patients, smokers, with alcoholic cirrhosis, mean age 54.7 +/- 6 years, treated by sclerotherapy for bleeding esophageal varices. Variceal eradication was obtained following juxtacardial intravariceal injection of 1.5 p. 100 polidocanol in one case (100 ml), and 0.5 p. 100 polidocanol in 3 cases (90, 240 and 310 ml). Local complications were observed in all patients (ulcers: 3; stenosis: 1). Carcinoma of the lower third of the esophagus was detected 12, 20, 22 and 30 months after esophageal sclerosis. Carcinoma was circular (one case), semicircular (2 cases), and nodular superimposed on Barrett's esophagus (one case). Histologic features included squamous cell carcinoma in 3 cases and adenocarcinoma in one case. Sclerotherapy could lead to the development of carcinoma because of mucosal alterations. However, other high risk factors (age, alcohol-tobacco intoxication, Barrett's esophagus) and different histologic features suggest a causal association. Endoscopic follow-up of patients after esophageal sclerosis could confirm this hypothesis.

Paraneoplastic intestinal pseudo-obstruction as the presenting feature of small-cell lung cancer.

A previously healthy 50-year old man presented with acute small bowel obstruction. No etiology was found at laparotomy. Postoperatively, the patient remained symptomatic with nausea, vomiting and severe constipation. Gastroscopy revealed retained food in the stomach. Gastric emptying of solids and liquids was dramatically decreased at scintigraphy. The colon was dilated on X-ray study. Chest X-ray revealed a pneumopathy and a small-cell lung cancer was discovered at bronchoscopy. The patient died 5 months after onset. Histologic study of the gut showed widespread degeneration of the myenteric plexus with plasma cell infiltration, Schwann cell proliferation and a reduced number of neurons of which many were abnormal. Intestinal pseudo-obstruction can reveal a small-cell lung cancer; the mechanism of neuronal impairment leading to pseudo-obstruction remains unknown, but could be related to the pathophysiology of paraneoplastic syndromes.

[Late portal vein thrombosis caused by hematoma after liver transplantation]. / Thrombose porte tardive par hématome après transplantation hépatique.

Late portal vein thrombosis of liver grafts is uncommon and is usually revealed by variceal bleeding. We herein report a case of thrombosis discovered in an adult 10 months after liver transplantation, due to stenosis of the portal vein by extrinsic compression, probably secondary to a biopsy-induced hematoma. Development of venous collateral circulation allowed for normal function of the liver graft.

Antineutrophil cytoplasmic autoantibodies in inflammatory bowel diseases.

Antineutrophil cytoplasmic autoantibodies have been recently reported in sera from patients with inflammatory bowel disease. We report our experience based on 90 patients with ulcerative colitis, 148 patients with Crohn's disease, and 60 controls. Determination of antineutrophil cytoplasmic autoantibodies was performed by the indirect immunofluorescence technique on ethanol fixed leucocytes. The specificities for proteinase 3, myeloperoxidase, and lactoferrin were tested by enzyme-linked immunosorbent assay. Forty-three out of 90 (48%) patients with ulcerative colitis, 10 out of 148 (7%) patients with Crohn's disease, and none of controls were positive by indirect immunofluorescence technique. All patients but two with positive immunofluorescence exhibited a perinuclear staining pattern. Among patients with ulcerative colitis, there was no relationship between the presence of perinuclear antineutrophil cytoplasmic autoantibodies and disease location or activity. Seven out of 20 (35%) patients with ulcerative colitis who had a previous colectomy (including 1 with ileoanal anastomosis) had perinuclear antineutrophil cytoplasmic autoantibodies. Antineutrophil cytoplasmic autoantibody specificity was not directed against myeloperoxidase, proteinase 3 or lactoferrin in sera from patients with inflammatory bowel diseases. Inflammatory bowel diseases are associated with a new subset of antineutrophil cytoplasmic autoantibodies. Among patients with Crohn's disease and ulcerative colitis, the sensitivity and specificity of the presence of perinuclear antineutrophil cytoplasmic autoantibodies for ulcerative colitis was 46% and 93%, respectively. Their presence reinforces the likelihood of underlying immunologic dysregulation in ulcerative colitis. Identification of the autoantigen(s) to which these antibodies are directed might facilitate the understanding of inflammatory bowel disease pathophysiology.

[Pregnancy after hepatic transplantation: what is the maternal risk?]. / Grossesse après transplantation hépatique: quel est le risque maternel?

OBJECTIVES AND METHODS: We report 7 pregnancies which occurred from 1988 to 1995 in 5 women who underwent liver transplantation. The immunosuppression regimen associated cyclosporine, azathioprine and prednisone. RESULTS: Mean age at conception was 25. During pregnancy, cholestasis occurred in 2 women. None of the patients experienced rejection. An increase in serum creatinine was observed in 3 cases. Serum uric acid increased in the third trimester of pregnancy in 6 cases, associated with arterial hypertension in 3 cases. In 4 cases, toxemia led to premature delivery. Seven childbirths occurred between the 34th and 38th week of gestation, by vaginal delivery (n = 3) or caesarean section (n = 4). Newborn weights ranged from 1,350 g to 3,100 g. A favorable outcome was observed in all mothers, with a follow-up ranging from 2 months to 7 years after delivery. CONCLUSION: These results suggest that a successful pregnancy is possible after liver transplantation in young women with normal hepatic function and treated with cyclosporine. The risk of toxemia is mainly related to renal function before pregnancy.

[Gastric metastasis of a malignant melanoma of the choroid]. / Métastase gastrique d'un mélanome malin de la choroïde.

Gastric metastases of choroid malignant melanoma seem to be exceptional since less than 10 cases have been previously published. We report the case of a 71 year old patient with a gastric melanosarcoma secondary to a choroid malignant melanoma. Gastric metastasis was revealed by digestive bleeding occurring 18 years after right eye enucleation. Gastroscopy showed black ulcerated tumors. Histology confirmed the diagnosis portraying typical melanic pigments within the gastric mucosa. Laser photocoagulation of the gastric lesion was used for the first time in this indication. As a result, hemorrhage decreased and the patient's comfort was improved.

[Diffuse jejuno-ileitis of Crohn's disease: a separate form of the disease?]. / Maladie de Crohn jéjuno-iléale diffuse: une forme particulière de la maladie?

BACKGROUND AND AIMS: Diffuse jejuno-ileitis of Crohn's disease may be a homogeneous clinical subgroup. The aim of this work was to compare the demographic and clinical data at diagnosis and the initial treatments of patients with diffuse jejuno-ileitis of Crohn's disease and to the ones without this localization. PATIENTS AND METHODS: For demographic and clinical studies, 48 (32M/16F) incident cases of diffuse jejuno-ileitis of Crohn's disease diagnosed between 1988 and 1994 in the EPIMAD register were compared with 96 (48M/48F) controls diagnosed the same year. As far as for the therapeutic management, the 48 incident cases were compared with 48 controls. RESULTS: Diffuse jejuno-ileitis constituted 3.3% of the total incident cases. Median age at diagnosis was significantly lower (20 vs 23 years, P = 0.01) and an upper digestive involvement was more frequent (56% vs 34%, P = 0.03) in patients with diffuse jejuno-ileitis. These patients were more often treated by total parenteral nutrition (43.8% vs 19.6%, P = 0.01) or azathioprine (50% vs 20.8%, P = 0.005). Azathioprine was also introduced earlier (20.7 vs 40.3 months, P = 0.009). Surgery for resection was less often required in diffuse jejuno-ileitis than in controls (65.2% vs 99.8%, P = 0.02) while more stricturoplasties were performed (52.9% vs 10%, P = 0.003); overall surgical rates did not significantly differ in the 2 groups. CONCLUSION: Our series suggest that diffuse jejuno-ileitis of Crohn's disease is a subgroup of patients characterized by a young age at diagnosis, with more frequent and earlier requirement for azathioprine.
