Abstract Introduction: Treatment of hormone refractory prostate cancer (HRPC) has generally aimed at increasing symptom free survival in asymptomatic patients and improving quality of life in symptomatic patients. However, recent randomized studies might be shifting the paradigm towards achieving an improved overall survival.
Methods: Two large randomized controlled studies were conducted using mitoxantrone plus prednisone as a control arm compared to docetaxel-based regimens.
Results: In the TAX 327 trial, 3-weekly docetaxel plus prednisone proved significantly superior to mitoxantrone plus prednisone (an established reference regimen) in extending survival, reducing levels of prostate specific antigen (PSA), controlling pain and improving quality… More >

Abstract Introduction: Phimosis is defined as the inability to retract the foreskin. Differentiating between physiological phimosis and pathological phimosis is important, as the former is managed conservatively and the latter requires surgical intervention. Referrals of patients with physiological phimosis to urology clinics may create anxiety regarding the need for surgery amongst patients and parents, while unnecessarily expanding the waiting list for specialty assessment.
Objectives: To determine the ability of referring physicians to differentiate physiological from pathological phimosis, and to see whether there is any difference in this ability between generalists versus specialists.
Materials and methods: A retrospective chart review… More >

Abstract Objective: To characterize the natural history of uncomplicated urinary tract infection (uUTI) in a Canadian primary care environment from the patient's perspective.
Materials and methods: Female patients (n = 2323) with symptoms of uUTI were recruited by 581 family physicians who collected baseline demographic and clinical data and prescribed 500 mg/day extended release ciprofloxacin (Cipro® XL™). Follow-up data were collected 4 and 10 days later by patient telephone interview assessing uUTI symptoms, medication compliance, time to symptom resolution, impact on usual activities and overall satisfaction.
Results: Patients (mean age 40) had on average 3.56 uUTI symptoms at baseline,… More >

Abstract Using a group-theoretical approach in the Minkowski space we explore kinematic hardening rules from a viewpoint of the Poincaré group. The resultant models possess two intrinsic times q₀^a and q₀^b; the first q₀^a controls the on/off switch of plasticity, and the second q₀^b controls the pace of back stress during plastic deformation. We find that some existent kinematic hardening rules, including the modifications from the Armstrong-Frederick kinematic hardening rule, can be categorized into type I, type II and type III, which correspond respectively to q₀^b = 0, q₀^b = q₀^a and q₀^b ≠ q₀^a.

Abstract The establishment and maintenance of effective urinary tract drainage for patients with malignant extrinsic ureteric obstruction is a formidable challenge for the urologist. We have utilized an alternative method of urinary diversion, called Palliative Subcutaneous Tunneled Nephrostomy Tubes (PSTN), for long term urinary tract drainage when intracoropreal stenting has failed or is not tolerated. PSTN provides a simple and effective method of external urinary diversion and preservation of renal function. This technique should be an option in the armamentarium of urologists for management of malignant ureteral obstruction. More >
