[MRI evaluation in tracheal pathology. Comparison with tomography and x-ray computed tomography. Apropos of 30 cases].

The authors report a standardised comparison between MRI, CT and Tomography, in 30 cases of tracheal lesions (postintubation, tumors, external compressions and invasions). They conclude on the superiority of MRI because of its multiplanar visualisation, its soft-tissue contrast resolution and its capability to differentiate inflammatory granuloma.

[Plasma fibronectin. Role in severe infections and intensive care].

Plasma fibronectin (pFN) levels were measured in 52 patients throughout their stay in an intensive care unit. At the same time a close watch was kept for signs of sepsis. Low pFN levels regularly accompanied--but did not precede--infectious episodes and were also found in patients without septic complications.
