Peripheral blood monocytes obtained from 55 aged donors were evaluated for their chemotactic and phagocytic capacity. In the same subjects, polymorphonuclear cell-mediated functions were studied by chemotaxis, phagocytosis, nylon fiber adherence and nitroblue-tetrazolium reduction assay. Monocytes showed a normal chemotactic responsiveness to(More)
Mixed-typed cryoproteins, consisting of IgG and IgM, were demonstrated in the sera of four sisters. While the IgG component was polyclonal in every instance, in two of them the IgM component was found to be monoclonal with type chi light chains. Clinical diagnoses included the purpura-weakness-arthralgias syndrome, posthepatitis cirrhosis, congestive heart(More)
The regional activity of the contralateral primary (SI) and the bilateral secondary (SII) somatosensory areas during median nerve stimulations at five intensity levels (ranging from nonpainful motor threshold to moderate pain) was studied by means of functional magnetic resonance imaging (fMRI). The aim was to characterize the functional topography of SII(More)
The number of total knee arthroplasty (TKA) procedures continuously increases, with good to excellent results. In the last few years, new surgical techniques have been developed to improve prosthesis positioning. In this context, patient-specific instrumentation is included. The goal of this study was to compare the perioperative parameters and the spatial(More)
OBJECTIVE The purpose of this study was to evaluate the clinical efficacy and dose response relationship of three doses of gadobenate dimeglumine for MRI of the breast and to compare the results with those obtained after a dose of 0.1 mmol/kg of body weight of gadopentetate dimeglumine. SUBJECTS AND METHODS. Gadobenate dimeglumine at 0.05, 0.1, or 0.2(More)
We studied MEG and fMRI responses to electric median and tibial nerve stimulation in five healthy volunteers. The aim was to compare the results with those of a previous study using only fMRI on the primary and secondary somatosensory cortices in which the somatotopic organization of SII was observed with fMRI. In the present work we focus on the comparison(More)
AIM To describe the radiological appearance of normal and pathological findings resulting from mammary autologous fat injections (lipofilling). MATERIALS AND METHODS Informed consent and institutional review board approval were obtained. From January 2008 to December 2010, all patients that had undergone breast lipofilling at our institution (Catholic(More)
BACKGROUND The aim of the article is to systematically review published data about the comparison between positron emission tomography (PET) or PET/computed tomography (PET/CT) using Fluorine-18-Fluorodeoxyglucose (FDG) and whole-body magnetic resonance imaging (WB-MRI) in patients with different tumours. METHODS A comprehensive literature search of(More)
PURPOSE To evaluate the accuracy of contrast material-enhanced multi-detector row computed tomographic (CT) colonography for preoperative staging of colorectal cancer. MATERIALS AND METHODS Forty-one patients with colorectal carcinoma underwent preoperative contrast-enhanced multi-detector row CT colonography. Images were obtained in the arterial (start(More)
