BACKGROUND & AIMS Patients with hemochromatosis show variable phenotype expression. We evaluated the frequency of hemochromatosis gene (HFE) mutations and the contribution of HFE genotype, ancestral haplotype, ethnic background, and additional factors (alcohol intake, hepatitis viruses, and beta-thalassemia trait) to the severity of iron overload in a large(More)
Juvenile Hemochromatosis (JH) is a rare genetic disorder that causes iron overload. JH clinical features are similar to those of hemochromatosis (HFE), but the clinical course is more severe and is characterized by an earlier onset and by a prevalence of cardiac symptoms and endocrine dysfunctions. Here we describe seven Italian patients belonging to five(More)
Des-gamma-carboxyprothrombin level was measured by enzyme immunoassay in the plasma of 39 patients suffering from hepatocellular carcinoma and 26 controls. Two of these were anticoagulated by warfarin and revealed very high positive values; the remaining 24, 8 healthy subjects and 16 patients with cirrhosis or chronic hepatitis, were negative. Values(More)
Juvenile hemochromatosis is a rare genetic disorder that causes iron overload. Clinical complications, which include liver cirrhosis, heart failure, hypogonadotropic hypogonadism and diabetes, appear earlier and are more severe than in HFE-related hemochromatosis. This disorder, therefore, requires an aggressive therapeutic approach to achieve iron(More)
OBJECTIVES Respirophasic variation of inferior vena cava (IVC) size is affected by large variability with spontaneous breathing. This study aims at characterizing the dependence of IVC size on controlled changes in intrathoracic pressure. METHODS Ten healthy subjects, in supine position, performed controlled isovolumetric respiratory efforts at functional(More)
[Article] Semi-automated tracking and continuous monitoring of inferior vena cava diameter in simulated and experimental ultrasound imaging Semi-automated tracking and continuous monitoring of inferior vena cava diameter in simulated and experimental ultrasound imaging. Porto, the institutional repository of the Politecnico di Torino, is provided by the(More)
Assessment of respirophasic fluctuations in the diameter of the inferior vena cava (IVC) is detrimentally affected by its concomitant displacements. This study was aimed at presenting and validating a method to compensate for IVC movement artifacts while continuously measuring IVC diameter in an automated fashion (with minimal interaction with the user)(More)
