[Possibilities of CT typing of liposarcomas]. / Possibilità di tipizzazione dei liposarcomi con TC.

Twenty-nine cases of liposarcomas were examined by CT; in 60% of them the CT finding was that of an ill defined, often large mass with content uniformly dishomogeneous and CT numbers ranging from -40 to +28 H.U. Diagnosis of liposarcoma is often possible when this finding is recognized in a mass of the thigh or retroperitoneum where these tumors frequently arise. Authors report differential diagnosis between liposarcomas and other lipomatous tumors such as angiomyolipoma of the kidney (when it is large and only attached to the kidney by an inconspicuous pedicle) and intramuscular lipomas (50% of them are located in the thigh).

[Glycoprotein changes in acute myocardial infarction (author's transl)]. / Modificazioni dell'assetto glicoproteico durante la fase acuta dell'infarto miocardico.

The changes of 11 plasma glycoproteins have been recorded during the first month in 22 patients with acute myocardial infarction; the quantitations have been performed by radial immunodiffusion on plates. The IgM proteins are significantly augmented and, with lesser degree, the alpha1 acid glycoprotein, the alpha1 antitrypsin and the haptoglobin are significantly augmented too. The peak is noted on the tenth day (the alpha1 acid glycoprotein only has its peak in twentieth day). To explain these changes we can consider: 1) the inflammatory reaction; 2) the repair reaction; 3) the autoimmune response. The complete explanation of these findings needs time: in the mean time we could use the IgM changes as a test in the second stage diagnosis of the acute myocardial infarction as well as the tests used so far.
