Microscopic colitis related to food supplement containing turmeric: a review of 3 cases.

Microscopic colitis is a chronic inflammatory disorder of the colon characterized by microscopic changes in the intestinal lining. Turmeric, a commonly used spice, is generally regarded as beneficial for digestive and articular health thanks to its anti-inflammatory properties. No cases of microscopic colitis under a food supplement containing turmeric has been previously described in the literature. This article highlights 3 cases where the consumption of a specific turmeric-based supplement caused microscopic colitis. Each of them complained about profuse watery diarrhea shortly after initiating the food supplement containing turmeric. Ileo-colonoscopies with biopsies confirmed the diagnosis of microscopic colitis, with two cases classified as lymphocytic colitis and the third as collagenous colitis. Following the discontinuation of the supplement, all patients experienced a resolution of their symptoms within a few days. Subsequent control biopsies for the three patients confirmed the resolution of microscopic colitis.

Macroscopic endoscopic lesions in microscopic collagenous colitis: double case report and review of the literature.

Collagenous colitis is a cause of chronic diarrhea of incompletely elucidated origin, defined by normal laboratory tests, a normal endoscopic appearance of colonic mucosa and specific microscopic inflammatory features on colonic biopsies. We report two cases of macroscopic endoscopic lesions observed in patients suffering from chronic diarrhea, whose biopsies confirmed a diagnosis of collagenous colitis and who were successfully treated in that setting, achieving clinical and endoscopic remissions. By means of a literature review, we summarize what is known about collagenous colitis. We particularly discuss macroscopic findings in that context, drawing attention on the so called "microscopic colitis" in the differential diagnosis of that type of lesions.

Upper gastrointestinal bleeding: what has changed during the last 20 years?

AIM OF THE STUDY: The purpose of this study was to assess the clinical, epidemiological, therapeutic and prognostic changes observed in patients with upper gastrointestinal bleeding (UGIB) during the last two decades. METHODS: Two cohorts of 200 patients with UGIB consecutively recruited during the period 1984-1987 (cohort A) then during the period 2004-2006 (cohort B) were compared. RESULTS: Median age was 61.5 years in the cohort A and 67 years in the cohort B. The main etiologies remained variceal bleeding and peptic ulcer, but esophagitis and Mallory-Weiss syndrome were more frequently observed recently. The intake of gastrotoxic drugs did not decreased despite the widely acknowledged harmful effects of these drugs. Regarding management practices, a therapeutic intervention during the first endoscopy was performed in 36% of the cases in the cohort B but only in 2% of the cases 20 years ago. The frequency and the volume of blood transfusion dramatically decreased during the last two decades. Regarding the outcome, the requirement for surgery and the rate of recurrent bleeding decreased by half, but mortality remained unchanged. CONCLUSION: The main changes observed in patients admitted for UGIB 20 years apart concerned epidemiological features, treatment and prognosis.

Epidemiology of coeliac disease.

In this article we review recent worldwide epidemiological data of coeliac disease (CD). An emphasis is made on adult figures as there is reduction of infants cases that is counterbalanced by the increase of CD in older children or adults. We review data from Europe, USA, South America, Australia, Asia and Africa. Studies in mixed population and in patients undergoing endoscopy are also mentioned. The prevalence of the disease varies between 1/100-500 in different continents. It is possible that the low incidence of CD in some regions is due to the decrease of the prevalence of classic form of the disease.

Impact of hepatitis C virus infection on the aetiology of cirrhosis and hepatocarcinoma in three affiliated hospitals in southern Belgium.

In a consecutive series of 411 patients with cirrhosis attending the outpatient liver clinics of 3 general hospitals located in the southern part of Belgium, hepatitis C virus infection accounted for 20% of the cases, far behind alcohol (63%). However, in a consecutive series of 57 hepatocarcinoma superimposed on cirrhosis, hepatitis C virus infection was the main aetiological factor accounting for 44% of the cases.

[lymphocytic colitis associated with lansoprazole treatment]. / Colite lymphocytaire associée à la prise de lansoprazole.

We report two cases of lymphocytic colitis with severe diarrhea in patients treated by lansoprazole for six weeks. Complete remission occurred rapidly after lansoprazole withdrawal.

Surveillance for hepatocellular carcinoma: compliance and results according to the aetiology of cirrhosis in a cohort of 141 patients.

Surveillance for early detection of hepatocarcinoma (HCC) in patients with cirrhosis is widely accepted. In a cohort of 141 patients with cirrhosis collected during the year 1995, we conducted a surveillance program by performing liver ultrasonography and blood alpha-foetoprotein measurement every 6 months. The median follow-up was 34 months. This study addressed to two questions: the compliance to the surveillance schedule according to the aetiology of cirrhosis and the results in terms of emergence of HCC and outcome. Aetiology of cirrhosis was alcohol-induced in 86 (61%), HCV-related in 30 (21%) and from other origins in 25 (18%). Compliance to the program schedule was good in patients with HCV-related cirrhosis (29/30--97%) and patients with cirrhosis of "other origins" (20/25--80%) but was poor in patients with alcoholic cirrhosis (45/86--52%). The lack of compliance was significantly linked to the failure to achieve alcohol abstinence. During follow-up, 6 HCC lesions were observed in 6 male patients with median age of 68 years. All 6 HCC were single nodule, less than 4 cm and accessible to percutaneous acetic acid injection. Nevertheless, the outcome was disappointing, four patients dying 3-15 months later (median: 8 months), two of them with extensive HCC. One of the two patients still alive developed extensive HCC, 36 months after percutaneous acetic acid injection.

Thromboembolism in inflammatory bowel disease.

Thromboembolism represents a severe complication of inflammatory bowel disease occurring in young patient, with active disease. Deep venous thrombosis and pulmonary embolism are the most frequent thromboembolism manifestations. Arterial complications and unusual sites for thromboembolism are more rare. Overall, inflammatory bowel disease is a real prothrombotic state as almost all parameters of coagulation are enhanced. Anticoagulation during the episode of thromboembolism is mandatory, and sometimes may ameliorate the course of inflammatory bowel disease.

Hypoxic hepatitis: a difficult diagnosis when the cardiomyopathy remains unrecognized and the course of liver enzymes follows an atypical pattern. A report of two cases.

In a clinical setting of cardiac or circulatory failure, the diagnosis of hypoxic (ischaemic) hepatitis is easy and can be elicited on mere clinical and biochemical features. We report two cases of hypoxic hepatitis where cardiomyopathy remained unrecognized at admission due to the lack of conventional signs of congestive heart failure and where the increase in liver enzymes activities followed an atypical pattern, characterized by only moderate elevation of serum aminotransferases activities, low ASAT/ALAT ratio and elevated ALAT/LDH ratio. This atypical pattern not suggestive of hypoxic hepatitis, could be explained by a delay between the onset of hypoxic injury of the liver and admission to hospital. Moreover one case was complicated by frank jaundice, an unusual feature in hypoxic hepatitis. Consequently, diagnosis and appropriate inotropic treatment were delayed resulting in progressive deterioration and eventually death of both patients. The report of these two cases and the review of other similar cases previously published, enlighten some atypical features of hypoxic hepatitis.

Severe nontyphoidal salmonellosis probably in relation with omeprazole treatment: report of 2 cases.

We report 2 cases of severe nontyphoidal salmonellosis (Salmonella enteritidis), occurring 4 and 5 weeks after starting a treatment with Omeprazole (20 mg a day). No other member of the families was sick, and none of the 2 patients took any meals outside home during the two weeks preceding the first symptoms. Gastric hypochlorhydria is a major risk factor for Salmonella enteritidis, and several cases of severe infection have been described with this condition. After a review of the literature we conclude that patients with diminished gastric acid run an increased risk of developing Salmonella infection and often with a more serious clinical course.

[Can the L/A ratio identify acute alcoholic pancreatitis?]. / Le rapport L/A permet-il d'identifier les pancréatites aiguës alcooliques?

Early distinction between acute alcoholic pancreatitis is important, because of possible emergency endoscopic sphincterotomy in case of biliary pancreatitis. The aim of this study was to evaluate the value of L/A ratio in the diagnosis of acute alcoholic pancreatitis. From 1990 to end 1993, 133 patients with acute pancreatitis were reviewed. Inclusion criteria were: 1) abdominal pain, 2) pathological serum amylase or serum lipase on admission or within 24 hours after beginning or abdominal pain, 3) acute pancreatitis at the echography or CT scan within 48 hours after admission. 60 patients met the inclusion criteria (31 alcoholic pancreatitis, 19 biliary pancreatitis and 10 pancreatitis of other causes). L/A ratio was studied in terms of delay from beginning of abdominal pain. There was no statistical difference between alcoholic and biliary pancreatitis at any time of the study, with the exception of admission. AST, ALT and alkaline phosphatase were higher in biliary pancreatitis than in alcoholic pancreatitis. AST and ALT were the best biochemical tests to diagnose biliary pancreatitis. Blamey's criteria can also contribute to diagnose biliary pancreatitis. These biochemical tests are the most helpful if they are collected very soon in the evolution of acute pancreatitis. It is concluded that L/A ratio is not helpful in the diagnosis of alcoholic acute pancreatitis.

[Primary osteosarcoma of the left auricle. Report of a case]. / Ostéosarcome primitif de l'oreillette gauche. A propos d'une observation.

We observed a fatal case of cardiac tumor obstructing the left atrium. Death occurred after massive hemoptysis. At autopsy, the histological diagnosis was primary cardiac osteosarcoma with metastases in the adrenal gland.

Endoscopic laser therapy for small villous adenomas of the duodenum.

Six patients with seven small, nonampullary duodenal villous or tubulovillous adenomas, two of which showed mild dysplasia, were treated by laser photocoagulation. The mean size of the tumors was 19 +/- 16 mm. Both argon and Nd-YAG lasers were used. All tumors were destroyed in one to five sessions. Recurrences of the lesion in two cases were successfully retreated, and both patients remained free of recurrence after 33 and 48 months, respectively. After a median follow-up of 59 months, all patients remained in remission, and five of them are still alive. One died after six months from a bronchogenic carcinoma. After a total of 18 laser sessions, no serious side-effects were observed, two patients exhibiting a transient melena possibly related to the procedure. We conclude that laser therapy is a good alternative to surgery for nonampullary duodenal villous tumors, especially in high-risk patients. Endoscopic follow-up is mandatory to detect and treat recurrence.

High-dose cytosine arabinoside and amsacrine or mitoxantrone in relapsed and refractory acute myeloid leukaemia: a prospective randomized study.

52 patients with refractory or relapsed acute myeloid leukaemia (AML) were randomly assigned to receive a combination of high-dose cytosine arabinoside (HD Ara-C), 3 g/m2/d and either mitoxantrone (MTX), 7 mg/m2/d (5 mg if older than 60 yr) or m-amsacrine (AMSA), 120 mg/m2/d (90 mg if older than 60 yr) for 5 d. The overall response rate was 50% and did not differ significantly in the two groups (46% for AMSA and 56% for MTX, p = 0.415). The median survival was 11 months (8 months for AMSA and 12 months for MTX, p = 0.326) and the median duration of complete remission (CR) was 11 months for AMSA and 12 months for MTX (p = 0.643). In relapsed patients, the only significant predictive factor for obtaining a complete response was the length of first complete remission. Patients with a first CR shorter than 6 months had a CR rate of 36% while it was 65% if the first CR lasted more than 6 months (p = 0.03). Severe (WHO grade III-IV) gastro-intestinal toxicity was more frequent in the AMSA group (27% vs 4%, p = 0.021). Treatment-related death occurred in 4 patients in the AMSA group and in 2 patients in the MTX group (p = 0.097). We conclude that neither of these two treatment modalities was shown to be superior in terms of CR rate and survival, with a better tolerance for MTX.

[Exudative enteropathy caused by an acute graft-vs-host reaction. Apropos of a case report]. / Entéropathie exsudative causée par une réaction aiguë du greffon contre l'hôte. A propos d'une observation.

The authors report the case of a 41-year-old woman who developed an acute graft-versus-host disease following bone marrow transplantation for post-polycythemic myeloid metaplasia; liver, cutaneous and intestinal lesions were present, associated, with a severe protein-losing enteropathy. Symptoms, diagnostic procedures and therapy of intestinal graft-versus-host disease are reviewed. The intestinal clearance of alpha-1 antitrypsin was particularly useful to assess the response to medial treatment, which induced a complete remission.

[Ascitic fluid: the value of various biological tests in the differential diagnosis between cirrhotic and neoplastic ascites]. / Le liquide d'ascite: intérêt de divers tests biologiques dans le diagnostic différentiel entre ascite cirrhotique et néoplasique.

The authors have analyzed sixty cases of ascites including twenty of neoplastic origin and thirty-six of cirrhotic origin in order to evaluate the usefulness of several laboratory tests for the differential diagnosis of ascites. The tests which gave more than 85% diagnostic accuracy were ascitic fluid concentrations of fibronectin and total protein, serum-ascites gradients of albumin and total protein concentrations, ascitic fluid concentrations of albumin and cholesterol. The last three tests gave a diagnostic accuracy of more than 92% at discriminant levels of 3.8 gr/dl, 1.6 gr/dl and 60 mg/dl, respectively. For these six tests, neoplastic ascites due to liver metastasis had values intermediate between cirrhotic ascites and neoplastic ascites due to peritoneal carcinomatosis. A serum-ascites albumin gradient of more than 1.1 gr/dl was indicative of portal hypertension in cirrhotic patients; the total protein serum-ascites gradient had a better diagnostic accuracy. Flow cytometry had less diagnostic accuracy than cytology; moreover, all cases with abnormal flow cytometry were already recognized by cytology.
