Alterations of the serum peptidome in renal cell carcinoma discriminating benign and malignant kidney tumors.

Renal cell carcinoma (RCC) is typically asymptomatic and surgery usually increases patient's life only for early stage tumors. However, some cystic and solid renal lesions cannot be confidently differentiated from clear-cell-RCC. Therefore possible markers for early detection and to distinguish malignant kidney tumors are needed.

Bacterial sepsis following prostatic biopsy.

Purpose: Despite the recent innovations, complications of prostate biopsy can occur. The aim of this study was a prospective monitoring of major septic complications occurring after transrectal prostate biopsy, to describe their causing agents, to report the clinical course of these patients, and to give guidelines based on our personal experience.

Methods: This prospective study was carried out between January 2009 and September 2010.
