[The factor of magnification in mammography].

The last generation of mammographic equipment allows mammography to be performed with direct magnification techniques, thanks to such technical features as microfocus, high focus-film distance, high-power generators. The authors compared the diagnostic yield of two different equipment sets, with 1.4x and 2x magnification respectively, and verified the utility of magnification radiography. A significant reduction was obtained in questionable diagnoses (42 to 18) in a group of 63 patients, with no evidence of substantial differences in the diagnostic yield of the images obtained with different magnification ratios. An objective analysis of the system resolution power privileges 2x magnification ratio, which however implies an increase in the average dose to the breast. The use of faster recording systems reduces the dose by 50%, though maintaining good image quality.

[Sonographic structural and morphological features of the parathyroid glands in patients on dialysis. Observations concerning 75 patients].

The results of US study concerning parathyroid glands performed in 75 uremic patients on regular haemodialysis, examined by echography, are reported. The purpose of this research is the identification of the glands and the analysis of their sonographic features. The results show that parathyroids mostly have round shape and regular outlines, usually hypoechoic structure. The authors stress the use of US as a useful tool for visualization and anatomical definition of parathyroids, providing important information for surgical planning.

[Clinical, radiological and ultrasonic correlations in secondary hyperparathyroidism. Observations concerning 75 patients on dialysis].

The results of a US study on parathyroid glands, performed in 75 hemodialysed patients are reported. The correlation between morphological features of the glands, biochemical and radiological pattern of secondary hyperparathyroidism is stressed. The results show a significant link between gland volume and hematic level of PTH: less interesting appears the correlation with radiological pattern of uremic osteodystrophy.

Effects fo streptozotocin in the WDHA syndrome not amenable to radical surgery.

Two cases of Verner-MOrrison syndrome due to pancreatic carcinoma were treated H. h streptozotocin (STZ) according to the schedule suggested by the Division of Cancer Treatment of the National Cancer Institute. In both patients the drug caused a remission of the WDHA syndrome: therefore, this finding seems to recommend such treatment when the syndrome is not amenable to radical surgery. Renal toxicity is, however, an important limitation. It occurs mostly when STZ is administered by iv infusion. In one of the patients, after a serious impairment of renal function caused by STZ, prednisone controlled the syndrome for a long period of time.
