PTTG-1 (Securin) immunoexpression in meningiomas correlates with tumor grade and proliferation rate: potential use as a diagnostic marker of malignancy.

This study essentially aims to contribute to the immunohistochemical investigation of the use of pituitary tumor transforming gene (PTTG) as a marker of cell proliferation or advanced tumor grade in meningiomas of various WHO grades. In all, 51 cases were recovered in total, 21 Grade-I, 23 Grade-II and 7 Grade-III meningiomas. Mitotic index (MI), Ki-67/MiB-1 positivity percentage and PTTG expression were analyzed in correlation to each other as well as to the tumor WHO grades.

Deep sedation in GreenLight laser prostatectomy.

Introduction: Evaluation of ketamine and propofol combination for the performance of photoselective vaporization of prostate (PVP).

Patients And Methods: Twenty-six patients undergoing PVP for benign prostatic hyperplasia were included in the study. Co-morbidities were present in 24 patients.

Ectopic parathyroid adenoma located inside the hypoglossal nerve.

Background: Intraneural parathyroid adenomas are extremely rare, with only 9 cases of intravagal adenomas reported. We report the first case of an ectopic parathyroid adenoma located within the hypoglossal nerve.

Methods And Results: A 62-year-old woman presented with a palpable nodule in the right submandibular area, reduced bone mass, and elevated calcium and parathormone levels.

Ureteric response to abdominal radiotherapy and metallic double-pigtail ureteric stents: a pig model.

Objective: To examine the safety and compatibility of full-length metal ureteric stents with abdominal radiotherapy.

Materials And Methods: Four ureteric stents (Resonance(TM), Cook Urological, Ireland) (RS) and four RSs specially modified to contain thermocouples were placed unilaterally in eight pigs. The contralateral ureters of the same pigs served as their controls, and contained two polymeric ureteric catheters and two similar specially modified to contain thermocouples, while the remaining four control ureters remained intact.

Metallic double pigtail ureteral stent usage during extracorporeal shock wave lithotripsy in the swine model: is there any effect on the ureter?

Purpose: To examine the safety and compatibility of full-length metal ureteral stent usage with extracorporeal shock wave lithotripsy (SWL).

Methods: Four Resonance ureteral stents and four special Resonance ureteral stents modified to contain thermocouples were placed unilaterally in eight pigs, with contralateral ureter of each pig serving as its own control. All pigs were subjected to the same SWL protocol in both their ureters.

Application of paclitaxel-eluting metal stents in renal artery of pig model.

Background And Purpose: Recent reports concerning coronary, carotid, and femoral vasculature have proposed the use of drug-eluting metal stents (MS) to improve clinical and angiographic outcomes. Based on these reports, we used paclitaxel-eluting MS within an animal renal artery lumen and compared the results with those using a bare-metal stent.

Materials And Methods: The experimental model in this study was the female pig renal artery.
