Experience with omentoplasty.

A 6-year experience with omentoplasty is presented. During this period pedicled omentum was used in 145 procedures of reconstructive urologic surgery. On the basis of this experience the authors conclude that omentoplasty is an essential part in urological reconstructive surgery.

[Radiological evolution of renal pelvis tumours (author's transl)].

The tumours of renal pelvis show a polymorphic radiological pattern, often rather difficult to interpret, sometimes even not evident owing to the presence of some other pathology. The most characteristic cases, and to be considered specimen, found in researches executed at different times, are represented by carcinomas, among which the ones showing the most elevated histological malignancy present a more rapid and infiltrative growth, as testified by repeated radiological tests.

[Relations between athero-arteriosclerosis and chronic liver diseases. Anatomopathological and statistical studies].

Starting from well known anatomopathological premises and on the basis of relative physiopathological concepts, particularly lipid metabolism and the lipidaemic fractions in patients suffering from chronic hepatopathy and athero-arteriosclerosis, a statistical investigation was carried out into the relations between the two disease conditions on the basis of the anatomopathological material collected over a period of six years in the S. Giovanni and S. Giacomo Hospitals in Rome. The conclusion is that there is a smaller incidence of athero-arteriosclerotic pathology in patients suffering from chronic hepatopathy up to the sixth decade of life.

Peripheral small vessel involvement in chronic nephritides.

Small cutaneous vessels, obtained by ear lobe biopsies, were studied in 14 patients with various chronic nephritides and in 10 normal controls. The capillaries in the group of patients with nephritis were found to undergo two main changes: thickening of the adventitia reticularis and perivascular cellular infiltration in an inverse ratio. This infiltration was seen to be made up of mononuclear cells and an increased number of mast cells in various stages of degranulation. Changes in the basement membrane as seen by electron microscopy are not constant. All of the above changes were absent in the controls and are similar to what has been described in previous studies in both experimental and spontaneous pathologic conditions, such as experimental hypertension, diabetes mellitus, scleroderma, rheumatoid arthritis, etc. Small vessel involvement in chronic nephritides could be part of a process of diffuse microvascular damage that includes the kidneys or it may be related to hypertension or to the biochemical changes which follow uremic and pre-uremic states.
