BACKGROUND After several days of loading, oral amiodarone, a class III antiarrhythmic, is highly effective in controlling ventricular tachyarrhythmias; however, the delay in onset of activity is not acceptable in patients with immediately life-threatening arrhythmias. Therefore, an intravenous form of therapy is advantageous. This study was designed to(More)
Alterations of glucose metabolism in diabetes have been suggested as promoting Helicobacter pylori colonization. We performed a cross-sectional sero-prevalence study of diabetic patients (insulin-dependent, or type 1, and non-insulin-dependent, or type 2, diabetes mellitus) with H. pylori and compared them with a control group. Consecutive diabetic(More)
BACKGROUND Patients with implantable cardioverter-defibrillators often receive adjunctive antiarrhythmic therapy to prevent frequent shocks. We tested the efficacy and safety of sotalol, a beta-blocker with class III antiarrhythmic effects, for this purpose. METHODS In a multicenter trial, patients were stratified according to left ventricular ejection(More)
We previously described a Sardinian family in which the probands had a severe form of hypercholesterolemia, suggestive of familial hypercholesterolemia (FH). However, low density lipoprotein (LDL) receptor activity in fibroblasts from these subjects and LDL binding ability were normal. The characteristics of the pedigree were consistent with an autosomal(More)
BACKGROUND Increased intestinal lactase activity has been shown to occur in alloxan and streptozotocin diabetic rats. OBJECTIVE The objective of this study was to determine whether increased intestinal lactase activity is present in humans with diabetes mellitus. DESIGN We assessed the capacity to digest lactose by measuring breath-hydrogen production(More)
We studied serum lipids and lipoproteins in 20 patients with beta-thalassemia major, under high transfusion programme and regular chelation therapy, and in 20 control subjects. Total cholesterol, HDL-cholesterol, HDL2-and HDL3-cholesterol, apolipoprotein A and B levels were significantly lower in patients with Cooley's anemia, whereas free cholesterol,(More)
A 23-year-old woman presented with sustained ventricular tachycardia and was found to have an endocardial mass by echocardiography and by magnetic resonance imaging. The diagnosis of cardiac endocardial tuberculoma was made, and she was treated with antituberculous therapy and an antiarrhythmic drug for one year. After a year, the mass was no longer(More)
OBJECTIVE To evaluate and quantitate cardiac involvement in myotonic dystrophy and assess whether the size of the trinucleotide (cytosine-thymine-guanine [CTG]) repeat expansion is a significant predictor of cardiac abnormalities. DESIGN Case-control study of a large kindred with myotonic dystrophy. PATIENTS Ninety-one bloodline members of the kindred(More)
