Background: P63 immunostaining has been considered as potential prognostic factor in laryngeal cancer. Considering that P63 is mainly nuclear stain, a possible correlation between the texture of P63-stained nuclei and the tumor's grade could be of value to diagnosis, since this may be related to biologic information imprinted as texture on P63 expressed nuclei.
Objective: To investigate the association between P63 stained nuclei and histologic grade in laryngeal tumor lesions.
Objective: To evaluate the use of a continent cutaneous pouch made exclusively of colon (Mainz pouch III), as excellent results with the Mainz pouch III in irradiated patients suggested that the indication for this type of urinary diversion could be extended.
Patients And Methods: The outcome of 24 patients with continent cutaneous urinary diversions using colon segments (Mainz pouch III) was investigated retrospectively. Overall, 22 of the patients had a malignant disease and two a benign disease; 16 had a hysterectomy and pelvic exenteration for gynaecological tumours; two men with a rhabdomyosarcoma of the prostate had a radical cystoprostatectomy; one woman had pelvic exenteration for bladder cancer; one man had a simultaneous rectum resection due to infiltrating rectal cancer, and another a left nephrectomy with cystectomy for concomitant kidney and bladder tumour.
Mini-laparotomy cholecystectomy versus laparoscopic cholecystectomy: which way to go?

Purpose: The aim of this paper is to report the results of a prospective clinical trial investigating traditional laparoscopic cholecystectomy versus "mini-lap" cholecystectomy in a tertiary care University Hospital.
Materials And Methods: This is a prospective, randomized, single-center observational study. Forty-four patients were allocated in each group; patients in group L underwent laparoscopic cholecystectomy, whereas patients in group M had open "mini-laparotomy" cholecystectomy with a small incision through the rectus abdominis muscle.
Purpose: The aim of the present study was to evaluate and quantify the antiangiogenetic effect of ionizing radiation on tumor angiogenesis using digital subtraction angiography (DSA) in conjunction with computer assisted image analysis (CAIA).
Methods: Walker 256 carcinosarcoma was inoculated in both glutei of 12 Wistar rats. When the tumors reached a diameter of 1.
Introduction: A technical modification of nerve sparing endoscopic extraperitoneal radical prostatectomy (nsEERPE) with preservation of the puboprostatic ligaments is presented and compared to a previous technique.
Materials And Methods: nsEERPE was performed in 100 men with clinically localized adenocarcinoma of the prostate from March 2004 through February 2005. Patients were divided into two groups: Group A included patients in whom a standard nsEERPE was performed (n=50), and group B included patients in whom a puboprostatic ligament sparing nsEERPE was performed (n=50).
Objective: In the present study we have applied virtual endoscopy (VE) in patients with ureteral metallic stents as a follow-up tool study especially in the need to define ureteral patency.
Methods: We performed the suggested technique in 6 patients with malignant ureteral obstruction treated successfully by placement of Wallstent intraureteral metallic stents, and correlated the results with antegrade nephrostomography 48 hours after initial stent placement.
Results: In 2 patients restenosis was observed, and in the remaining 4 patients the stented ureters remained patent during the follow up evaluation.
