An optimal approach to the diagnosis of deep vein thrombosis (DVT) in lower limbs in the emergency department is still unknown. In this prospective cohort study, we aimed to evaluate the accuracy of the widely available plasma D-dimer test (VIDAS) and establish the usefulness of combining D-dimer testing with a clinical model to reduce the need for serial(More)
BACKGROUND To evaluate the midterm results of patients with angina and diffuse coronary artery disease treated with transmyocardial revascularization in combination with autologous stem cell therapy. METHODS Nineteen patients with diffuse coronary artery disease and medically refractory class III/IV angina were evaluated between June 2007 and December(More)
The objective of this prospective study was to evaluate the sensitivity, specificity, positive and negative predictive values, and interobserver agreement in the diagnosis of pulmonary embolism with helical CT, compared with pulmonary angiography, for both global results and for selective vascular territories. Helical CT and pulmonary angiography were(More)
AIM To study if the caliber of the upper airway, measured by CT, allows us to distinguish patients with obstructive sleep apnea syndrome (OSAS) from healthy people. PATIENTS AND METHODS Sixteen OSAS patients (with an apnea-hypopnea index > 10) and 39 healthy volunteers were studied. Polysomnography and CT of the upper airways during awake periods were(More)
BACKGROUND Helical computed tomography has been introduced for the diagnosis of pulmonary embolism. OBJECTIVE To determine the clinical safety of withholding anticoagulant treatment in patients with suspicion of pulmonary embolism and negative helical computed tomography study. METHODS During a 9-month period, we performed a prospective study including(More)
BACKGROUND The authors studied changes in the upper airway in morbidly obese women and the relationship to sleep apnea-hypopnea syndrome (OSAS). METHODS Patients underwent a cardiorespiratory polygraphic study, respiratory function test (spirometry, plethysmography, maximum inspiratory pressures and arterial blood gas analysis), and computed tomographic(More)
To compare the worsening of structural lung disease on high-resolution computed tomography (HRCT) with changes in spirometry results in cystic fibrosis (CF) patients, and analyse factors associated with the worsening of structural lung disease over time. A total of 31 CF subjects (mean age 11.03 ± 3.67 years old) were prospectively evaluated by two HRCT and(More)
