Fiberoptic bronchoscopy and bronchoalveolar lavage are often followed by the development of fever and other influenza-like symptoms. We report the onset of these symptoms in a healthy volunteer following bronchoscopy and bronchoalveolar lavage; the symptoms were temporally associated with the dramatic elevation of serum levels of tumor necrosis factor. Our observations suggest that tumor necros...
Noninvasive MR acquisition of blood flow and stationary tissue provides three-dimensional display of flow and of the vascular and brain surfaces. The calculated motion of a simulated bolus injection is derived from the measured velocity vector field and is animated to resemble cine angiography. Simulation of a bolus injection into the basilar artery of a healthy volunteer shows the blood flow i...
Methods 15 patients with Marfan syndrome and no history of prior aortic dissection or surgery, and 18 healthy volunteer controls matched for age, sex and height underwent CMR at 3T (Siemens, Erlangen). Time-resolved, 3D velocity-encoded and magnitude data were acquired using a phase contrast CMR sequence (Figure 2). Each dataset was evaluated for flow disturbance by two independent observers, e...
OBJECTIVE The Game Dice Task (GDT) was developed to measure decision making under known risk. The aim of this study was to translate and adapt the GDT to a Brazilian population. METHOD After the GDT was translated and back-translated to Brazilian Portuguese and evaluated by eight bilingual judges, 175 Brazilian adults were divided into two groups - 160 healthy volunteers and 15 traumatic brai...
