[Papillomatous lesions of the biliary tract].

Biliary papillomatosis is a rare entity, characterized by single or multiple lesions arising from the biliary epithelium, leading to relapsing attacks of obstructive jaundice and cholangitis. Usually considered a benign disease, progression to malignancy has though been reported. In this paper the case of a 72 year old patient, with a single papilloma of the left hepatic duct treated by left hepatectomy, is discussed.

[Radiographic examination of the pelvis in patients under periodic hemodialysis for terminal uremia].

Significant signs of uremic osteodystrophy were found at Rx examination of the pelvis in 29 out of 72 uremic patients (40%) undergoing maintenance hemodialysis. It is therefore thought that Rx of the pelvis, although it is more significant for some signs (brown tumors, alterations of the trabecular structure, enlargement of Ward's triangle) than for others, such as subperiosteal resorption, should not be neglected in these patients.

[Surveillance by skeletal radiography of patients under hemodialysis. Radiographic examination of the vertebral column].

The authors describe damage to the spine observed by x-ray in patients on maintenance hemodialysis. They stress the importance of including x-ray examination of the spine among the routine checks performed in these patients.

[Chronic splenic tuberculosis. Description of a case].

The authors report a case of chronic splenic tuberculosis. They underline the diagnostic difficulties, notwithstanding the remarkable progresses in radiological technics, essentially related to the rarity of this tubercular site and they outlined the exact surgical indication to the splenectomy.
