Effects of severe hypertension on endothelial and platelet microparticles.

The molecular mechanisms by which extreme blood pressure elevation leads to vascular injury are not defined. To explore the hypothesis that activation of endothelium and platelets as manifested by increased concentrations of circulating endothelial microparticles and platelet microparticles could play a role in this target organ injury, we conducted a cross-sectional study of these markers in 3 groups: (1) untreated patients referred specifically for treatment of severe uncontrolled hypertension; (2) untreated patients with established mild hypertension; and (3) normotensive volunteer subjects. By ANOVA, endothelial (P=0.

[Transurethral tissue vaporization: indications and limitations of the technique. Our experience in 105 cases].

Introduction: Laser vaporisation of the prosthesis (LP) is now regarded as the most valid alternative to endoscopic resection (TUR). It is a safe, relatively non-invasive and clinically effective method but requires the use of very expensive instruments.

Aim: In order to obtain the same results but at a lower cost, an innovative technique has recently been introduced: "prostatic electrovaporisation" which uses a combination of coagulation and electrosurgical tissue vaporisation, and achieves the same biological effect as laser treatment using equipment already available for standard TUR merely by modifying the operator electrode.

[Nosocomial urinary infections. Comparison of experience in two urology centers].

The authors analysed the type and the sensitivity of most common micro-organism causing urinary infections in the urological wards of Savigliano (CN) and Turin. In Savigliano, these data show a remarkable increase in the incidence of Pseudomonas; in the other urological ward the data show an increased incidence of E. coli.

[Urethro-vesical anastomosis after radical prostatectomy and bladder replacement with the Camey II approach].

Owing to its numerous biological characteristics, Tissucol fibrin cement is widely used in general and specialised surgery. In urology it is used on both the renal parenchyma and on the entire urinary tract. The authors report their experience regarding the use of Tissucol in the execution of urethro-vescical anastomosis during radical prostatectomy and cystectomy with orthotopic neovescica according to Camey II.
