Abstract This paper analyzes computationally the flow field for the full geometry model of a commercial passenger airplane, Boeing747-400. The geometric dimension of an airplane was acquired by means of the reverse engineering technique adopting the photo scanning measurement. The steady three-dimensional viscous compressible flow field was calculated when the airplane cruises under side flow. The basic computational conditions were considered as the same to those of Boeing 747-400's cruising state, i.e., the atmospheric condition at 13 km above the sea level and Mach number of 0.85. The boundary conditions are the same that the freestream… More >

Abstract Symptomatic benign prostatic hyperplasia (BPH) is one of the commonest causes of men presenting with lower urinary tract symptoms (LUTS). We can fi nd this in 50% of men over the age of fi fty. If BPH is not treated, then one can expect that the disease will progress in a signifi cant number of individuals. What we need to do is try to predict, based on certain baseline parameters such as International Prostate Score (IPSS), prostate volume, prostate-specifi c antigen (PSA) and the degree of bother, those men to whom we should offer therapy.

Abstract A potential interaction between the local hemodynamics and the artery wall response has been suggested for vascular graft failure by intimal hyperplasia (IH). Among the various hemodynamic factors, wall shear stress has been implicated as the primary factor responsible for the development of IH. In order to explore the role of hemodynamics in the formation of IH in end-to-side anastomosis, computational fluid dynamics is employed. To validate the numerical simulations, comparisons with existing experimental data are performed for both steady and pulsatile flows. Generally, good agreement is observed with the velocity profiles whereas some discrepancies… More >

Abstract Background: The variable clinical behavior displayed by prostate cancer (PCa) warrants investigation of potential PCa-specific biomarkers that could identify more aggressive tumor types and therefore provide prognostic value. Upregulation of expression of human telomerase reverse transcriptase (hTERT), Survivin, DD3 and PCGEM1 mRNAs in PCa lesions has recently been described. The purpose of this study was to evaluate the clinical value of detection of overexpression of these biomarkers in the diagnosis and prognosis of PCa.
Material and methods: Archival formalin-fixed, paraffin-embedded (FFPE) prostatectomy tissue from 26 patients with PCa (Gleason score 3-9, mean 7) and 14 patients with… More >

Abstract Purpose: Prostatic intraepithelial neoplasia (PIN) is considered as a precursor lesion for adenocarcinoma of the prostate. Most data supporting this relationship comes from the short-term follow-up of patients with repeated biopsies. We report a study in which patients were followed-up for 11 years to assess the relationships between the presence of high grade PIN, low grade PIN, and atypical adenomatous hyperplasia (AAH) and the subsequent occurrence of prostate cancer.
Materials and methods: For 601 men treated by TURP in 1990-1993, prostate specimens were reviewed to assess the presence of high grade PIN, low grade PIN, and AAH.… More >

Abstract Objective: To develop the first Canadian guidelines for the management of lower urinary tract symptoms in men with benign prostatic hyperplasia (BPH).
Methods: These guidelines, developed under a mandate provided by the Canadian Urological Association (CUA), were a collaborative effort between the CUA guidelines committee and the Canadian Prostate Health Council. BPH guidelines developed by the American Urological Association, the European Association of Urology, the World Health Organization International Consultation on BPH, and similar committees from Germany, Sweden and Australia were reviewed. The committee further reviewed a systematic literature search, updated to May 2004, and systematically derived… More >

Abstract Introduction and objectives: A novel slow release formulation of alfuzosin should improve compliance by reducing dosing to one 10 mg tablet per day. The current study examined efficacy, at 9 days and 3 months, and safety of this formulation of alfuzosin in BPH patients.
Methods: ALF-X was a 3-month, non-comparative, observational study of 353 BPH patients from 39 Canadian Urology centres.
Results: At baseline (BL), mean age was 63.1±9.01 years, 92.6% of patients were Caucasian, 3.4% had a history of acute urinary retention, mean duration of the micturition disorder was 48.6±54.15 months, and mean PSA was 3.3±6.65 ng/mL.… More >

Abstract Classically, surgical options for very large prostate glands, not amenable to transurethral resection, include suprapubic or retropubic simple prostatectomy and Holmium laser enucleation of the prostate (HoLEP). We present a case managed with a laparoscopic simple prostatectomy. Technical considerations are discussed as well as possible advantages of this approach including decreased blood loss, faster patient recovery and improved visualization. More >

Abstract The 2003 American Urological Association (AUA) guideline on management of benign prostatic hyperplasia (BPH) was released at the AUA annual meeting in Chicago, April 2003 and the diagnosis and treatment recommendations were published later in 2003. It is likely that the 2003 AUA guideline on the management of BPH will have a profound effect on clinical urologic practice in the USA, but its influence on Canadian urological practice will be different because of our socialized medical system, manpower issues, availability of expensive technology and our unique Canadian perspective. The authors review the 2003 AUA guideline More >
