Segmental organization of the pig liver: anatomical basis of controlled partition for experimental grafting.

Segmental anatomy has been investigated on 54 pig livers by bench-top radiology and ultrasonography of hepatic and portal vessels and bile ducts and dissection of suprahepatic veins. Eight segments were recognized, homologous to those of the human liver. Major variations were found only of arterial distribution.

[Hematoma and fat necrosis of the breast: mammographic and echographic features].

The mammary gland is a common site for traumas which often lead to the formation of intraglandular hematomas. The abundance of fat tissue in this gland accounts for the relatively high frequency of fat necrosis and self-digestion of fat by lipases after traumas, i.e.

[Pulmonary tuberculosis and other mycobacterial infections in patients with AIDS].

Nowadays, the acquired immune deficiency syndrome (AIDS) is most certainly the major cause of the increased incidence of tuberculosis (TBC). A total of 138 patients (pts) with AIDS were referred to the Department of Infectious Diseases of the Hospital of Pisa, 1990-1991; 14 of them (10.1%) presented pulmonary TBC.

[The echographic picture of the breast following quadrantectomy and radiation therapy].

Our experience moved from the clinical relevance of an eventual positive role of US in the follow-up of breast cancers treated with conservative therapy. This trial was suggested by the more and more frequent use of conservative therapy an by the diagnostic difficulties offered by the breasts treated with surgery and radiation therapy. Aim of the study is to analyze the diagnostic value of US in the identification of local relapse in a group of 60 patients with breast carcinoma (stages I and II) treated with conservative therapy.
