Asian men, who consume a low fat/high fibre soya-based diet, have very much lower incidence of prostate cancer than men from North America and Europe. The soya bean is a rich source of the isoflavonic phyto-oestrogens, daidzein, genistein and equol, compounds which may be cancer-protective in Asian populations. The lignans, enterolactone and enterodiol,(More)
BACKGROUND Chinese men have lower incidences of prostate cancer compared to men from Europe and North America. Asians consume large quantities of soya, a rich source of isoflavanoids phyto-oestrogens and have high plasma and urinary levels of these compounds. The mammalian lignans, enterolactone and enterodiol, are another group of weak plant oestrogens and(More)
OBJECTIVE To present and describe the validity and reliability of the International Continence Society-Benign Prostatic Hyperplasia study quality-of-life (ICSQoL) instrument, a new set of questions to assess the impact of lower urinary tract symptoms (LUTS) on quality of life (QoL) in middle-aged and elderly men. PATIENTS AND METHODS The study comprised(More)
PURPOSE We assess the effect of finasteride, a 5alpha-reductase inhibitor, on objective voiding parameters in men with lower urinary tract symptoms and benign prostatic enlargement on digital rectal examination (known as clinical benign prostatic enlargement) in a double-blind placebo controlled multicenter study using strict standard pressure flow study(More)
Test-retest reliability of repeated voids in pressure-flow studies and the influence on maximum flow rate (Q(max)pQ), detrusor pressure at maximum flow rate (p(det)Qmax), voided volume, and residual urine were studied. Also the agreement in interpretation of pressure-flow tracings between investigators and a single blinded central reader acting as a quality(More)
OBJECTIVE To compare the efficacy and adverse effects of intramuscular etofenamate and intramuscular diclofenac in the relief of acute renal colic. PATIENTS AND METHODS A multicentre, randomised, single-blind study was performed in 119 patients admitted to the emergency room for renal colic. Patients were assigned to treatment with either etofenamate(More)
Four studies were carried out on 66 patients in order to examine the effect of bromocriptine in benign prostatic hypertrophy (BPH) and to clarify its mechanism of action. Two studies were clinical: the first was a double-blind, controlled trial (lasting 6 months) in which bromocriptine 5 mg/day was compared with placebo, and the second was an open study to(More)
Probably the most important demand on the career of a medical specialist is that of having to keep up-to-date both scientifically and professionally. But the onus does not fall only on the practitioner. The institutions involved in medical teaching and professional development also have a crucial role to play by providing opportunities for continuing(More)
The author raises some doubts regarding arguments that have been used to justify the increase in the number of radical prostatectomies in localized prostate cancer. In well or moderately differentiated localized prostate cancer who undergo radical prostatectomy do not show marked differences in mortality in relation to patients subjected only to watchful(More)
