PURPOSE To report the results of a three-year observational pilot study of lung cancer screening with low dose computed tomography (CT) and to present the study design of a randomised clinical trial named as ''Italung-CT''. MATERIALS AND METHODS Sixty (47 males and 13 females, mean age 64+/-4.5 years) heavy smokers (at least 20 packs-year) underwent three(More)
PURPOSE To describe the percutaneous nephrostomy technique used at our centre in the treatment of supravesical urinary tract obstruction and to analyse the results obtained. MATERIALS AND METHODS Three-hundred and seventy-three patients underwent 412 percutaneous nephrostomies, most of which (78%) in an emergency setting, performed with a newly devised(More)
BACKGROUND Bone scan (BS), chest X-rays (CXR), liver ultrasonography (LUS) and laboratory parameters (LP) are frequently used as routine staging procedures for breast cancer patients. These procedures are not always appropriate in either clinical or research settings, regardless of the stage. The aim of this study was to identify groups of patients with(More)
AIMS Risk stratification of patients with Brugada electrocardiogram (ECG) is being strongly debated. Conflicting results have been suggested from international registries, which enrolled non-consecutive cases, studied with different programmed electrical stimulation (PES) protocols. The aim of this study was to prospectively evaluate the incidence of(More)
An unusual case of probable opioid poisoning due to atypical absorption of morphine sulphate through the oral mucosa is reported. A patient with advanced laryngeal cancer, who was unable to swallow, became stuporous, bradypneic, and cyanotic and had pinpoint pupils 1 hour after taking a controlled-release tablet of morphine sulphate 30 mg. Intravenous(More)
OBJECTIVE Prior analyses of X-ray exposures in lung cancer screening with CT considered the basic acquisition technique in single-detector scanners and the effects of a lifetime screening regimen, whereas the potential benefit in terms of lives saved was not addressed. MATERIALS AND METHODS We determined the total-body effective dose of different(More)
Background. Improved life expectancy of children with chronic renal failure (CRF) has increased the number of patients with renal osteodystrophy and has brought to light novel and severe forms of the disease. These factors have contributed to the need to evaluate new, noninvasive imaging modalities for the detection of bone involvement. Objectives. To(More)
The accurate locoregional staging of rectal cancer is important in choosing and planning therapy. The diagnostic contribution of endorectal ultrasonography and of Computed Tomography is well known because both methods have been widely used in the last ten years. More recently, Magnetic Resonance Imaging (MRI) has been introduced in the preoperative staging(More)
Clostridium difficile (C. difficile) infection (CDI) is the main cause of nosocomial antibiotic-associated colitis and increased incidence of community-associated diarrhea in industrialized countries. At present, the primary treatment of CDI is antibiotic administration, which is effective but often associated with recurrence, especially in the elderly.(More)
PURPOSE We report our experience with large core biopsy (LCB: 14-Gauge needles) of questionable or suspicious breast lesions detected at mammography and/or US. All biopsies were performed under instrumental guidance. We also report on technique, costs, time, advantages and disadvantages of the method and, finally, give precise indications on when and why(More)
