BACKGROUND & AIMS Epidemiologic and experimental studies have suggested that aspirin intake reduces the risk for colorectal carcinogenesis. However, the available data are not sufficient to serve as the basis for firm recommendations. METHODS We randomly assigned 272 patients with a history of colorectal adenomas (at least one more than 5 mm in diameter,(More)
BACKGROUND Reflux oesophagitis is considered a multifactorial disease, but the respective roles of the main factors involved in its pathophysiology have not been clearly established. AIMS To attempt to assign these roles by means of a multivariate logistic regression analysis of the main parameters associated with reflux oesophagitis. PATIENTS Eighty(More)
Transforming growth factor beta 1 (TGF beta 1) is a cytokine involved in liver fibrogenesis. Previous semiquantitative studies of patients with chronic viral hepatitis showed that liver TGF beta 1 messenger RNA (mRNA) was increased, compared with normal controls and with patients with chronic hepatitis C virus (HCV) infection who responded favorably to(More)
PURPOSE AND METHODS In order to evaluate the prevalence of positive hepatitis C virus (HCV) serology and cryoglobulinemia in human immunodeficiency virus (HIV)-infected patients, the prevalence and the clinical significance of cryoglobulinemia were prospectively studied in a cohort of 86 HIV-infected subjects seen as outpatients. They were compared to a(More)
The hypothalamo-pituitary gonadal function was evaluated in eleven chronically alcoholic menopausal women by measurement of basal serum oestradiol, FSH, LH and prolactin, followed by LHRH-TRH test and administration of clomiphene citrate. All patients had hepatic damage, fibrosteatosis or cirrhosis. Two subgroups have been isolated according to urinary and(More)
BACKGROUND & AIMS Recent studies have suggested that esophageal human papillomavirus infection could be a risk factor for esophageal squamous cell carcinoma. The aim of this study was to evaluate the prevalence of human papillomavirus DNA sequences in the esophagus of French patients with esophageal squamous cell carcinoma. METHODS Multiplex polymerase(More)
Recent reports suggest that hepatitis C virus (HCV) might be a causative agent of mixed cryoglobulinemia. To determine whether the HCV genotype is a factor implicated in the onset of cryoglobulinemia, genotyping by direct sequencing of polymerase chain reaction products of the 5' non coding region was carried out among 45 HCV-infected patients. Genotypes 1(More)
The kinetics of cholesterol labeling was studied in the plasma lipoproteins of three subjects who had received an oral dose of octadeuterated cholesterol and an intravenous administration of 3H-cholesterol and 14C-mevalonate or 13C-acetate. After each labeled cholesterol pulse into the plasma (absorption, exchange, or synthesis), the isotopic concentrations(More)
Cystic dystrophy of the duodenal wall developing in heterotopic pancreas is a rare disease. Weight loss and painless vomiting due to duodenal stenosis where the main clinical manifestations of this entity in a chronic alcoholic patient. Diagnosis was made by using an ultrasonic-endoscope equipped with a miniprobe. Although surgical treatment is usually(More)
