PURPOSE In industrialized countries the prevalence of upper urinary tract stones has continually increased during the 20th century, but there are considerable differences between countries and also within the same country. To study whether there is still an increase in the frequency of renal stones, an investigation was undertaken to determine the(More)
The question of a familial predisposition towards stone formation in primary nephrolithiasis has not been explored completely. In a sample of 214 calcium stone patients, and 428 age and sex-matched controls we observed a higher frequency of stones among the first degree relatives of stone patients compared to the relatives of controls. A family history of(More)
The authors briefly illustrate some biological and epidemiologic characteristics of the malignant urologic tumors; then they describe the modalities of metastasizing underlining that this process is determined not only by hematic and lymphatic dissemination but also by sequential and complex events "metastatic fall", involving multiple guest-tumor(More)
We studied the effect of oral Bacillus subtilis spore administration in a group of 95 patients with stones-associated recurrent urinary tract infections. There was a significant reduction in the frequency of infection episodes in the group treated with Bacillus subtilis spores plus antibiotics (treated group) compared with the group treated with antibiotics(More)
The best knowledge of the biological and genetic mechanism involved in the process of metastasizing must determine the attempt of elaborating new therapeutical modalities. The authors show the sequential events of the metastasizing process based on the most recent theories, underlining the way the organotropism of the neoplastic cells can be the explanation(More)
The Author describes the etiopathogenetic and histological aspects of leukoplakia in comparison with the squamous metaplasia of vaginal type (trigonal leukoplakia). They present a description both under anatomic and clinic point of view to achieve a correct diagnostic and therapeutical assessment to give a standardization of the term "leukoplakia" which is(More)
