Cystic fibrosis: are volumetric ultra-low-dose expiratory CT scans sufficient for monitoring related lung disease?
To assess whether chest computed tomography (CT) scores from ultra-low-dose end-expiratory scans alone could suffice for assessment of all cystic fibrosis (CF)-related structural lung abnormalities. ⋯ In this pilot study, CT scores from end-expiratory and end-inspiratory CT match closely, suggesting that ultra-low-dose end-expiratory CT alone may be sufficient for monitoring CF-related lung disease. This would help reduce radiation dose for a single investigation by up to 75%.

To assess the feasibility and safety of ultrasonographic (US) guidance in the placement of nontunneled central venous catheters (CVCs) in patients with cancer who had altered coagulation profiles. ⋯ In patients with cancer who had coagulation disorders, nontunneled CVC placement with US guidance was feasible and safe and did not require correction of coagulation parameters.

To evaluate the safety and efficacy of stent-assisted embolization of ruptured wide-necked intracranial aneurysms during acute subarachnoid hemorrhage (SAH). ⋯ Stent-assisted coil embolization is a feasible method for the endovascular treatment of wide-necked intracranial aneurysms that are difficult to treat surgically or with balloon-assisted embolization during acute SAH. The risk of subsequent rerupture of the aneurysm seems to be reduced for aneurysms treated early compared with that for nonsecured aneurysms.
