Predictive value of time-intensity curves obtained with contrast-enhanced ultrasonography (CEUS) in the follow-up of 30 patients with Crohn's disease.

Objectives: CEUS can provide accurate quantitative estimates of intestinal wall microvascularization in Crohn's disease. We hypothesized that inflammation of the intestinal wall is correlated not with the amount of wall vascularization (study of vascularization patterns, SVP) but with the degree of wall flow during a period of time (time-intensity study, TIS). Our objective was to discover whether CEUS SPV and/or CEUS-TIS reflect(s) vascular inflammation of the intestinal wall and display(s) correlation with clinical activity of the disease at the time of the examination (T0) or at the 3- and 6-month follow-up (T3, T6).

Imaging detection of new HCCs in cirrhotic patients treated with different techniques: Comparison of conventional US, spiral CT, and 3-dimensional contrast-enhanced US with the Navigator technique (Nav 3D CEUS)().

Introduction: The commercially available Navigator system(©) (Esaote, Italy) allows easy 3D reconstruction of a single 2D acquisition of contrast-enhanced US (CEUS) imaging of the whole liver (with volumetric correction provided by the electromagnetic device of the Navigator(©)). The aim of our study was to compare the efficacy of this panoramic technique (Nav 3D CEUS) with that of conventional US and spiral CT in the detection of new hepatic lesions in patients treated for hepatocellular carcinoma (HCC).

Materials And Methods: From November 2006 to May 2007, we performed conventional US, Nav 3D CEUS, and spiral CT on 72 cirrhotic patients previously treated for 1 or more HCCs (M/F: 38/34; all HCV-positive; Child: A/B 58/14) (1 examination: 48 patients; 2 examinations: 20 patients; 3 examinations: 4 patients).

Sweet's syndrome associated with monosomy 7 myelodysplastic syndrome.

Acute febrile neutrophilic dermatosis (Sweet's syndrome) is a reactive skin process frequently associated with inflammatory and neoplastic diseases, but particularly with hematologic malignancies. It usually precedes the underlying disorders for months or even years. Much of the evidence for this is based on a small series of case reports and reviews of the literature.

Interferon-alpha plus ribavirin in chronic hepatitis C resistant to previous interferon-alpha course: results of a randomized multicenter trial.

Background/aims: Interferon-alpha plus ribavirin seem to be more efficacious than interferon monotherapy in chronic hepatitis C. In a multicenter randomized trial, we evaluated the efficacy of this association for interferon-alpha resistant chronic hepatitis C.

Methods: Fifty patients who were non-responders to recombinant or lymphoblastoid interferon-alpha were randomized to receive either ribavirin (800 mg/day) plus leucocytic interferon-alpha (3 mega units thrice weekly) or the same dose of interferon-alpha alone, for 6 months.

Association between hepatitis C virus and non-Hodgkin's lymphoma, and effects of viral infection on histologic subtype and clinical course.

Purpose: Because an etiologic role for hepatitis C virus in non-Hodgkin's B-cell lymphoma has been suggested by several reports, we assessed the prevalence of hepatitis C virus infection in patients with non-Hodgkin's B lymphoma and in controls, and evaluated the influence of viral infection on histologic and clinical features of the lymphoma patients.

Patients And Methods: We prospectively investigated 175 consecutive patients with non-Hodgkin's lymphoma and 350 controls for serologic and molecular markers of hepatitis C virus infection. Controls were selected from inpatients (n = 175) and outpatients (n = 175) cared for at our hospital.
