We investigated the effect of prostatic inflammation on prostate-specific antigen (PSA) and per cent-free PSA levels changing after antibacterial therapy. We evaluated 48 patients whose PSA levels were between 4 and 10 ng/ml, without any suspicious findings on digital rectal examination, with no infection findings in urine analysis. Prostatic inflammation was assessed with prostatic massage. All the patients were given antibiotic therapy for 3 weeks. Patients were re-evaluated 3 weeks after antibacterial therapy with PSA (free/total) and urinalysis. Ten core biopsies were taken with transrectal ultrasound. No differences were found in terms of age, pre-and post-treatment PSA, and PSA varying between patients with and without inflammation in the prostatic massage. In 18 patients, PSA decreased below 4 ng/ml. Prostate cancer was found in 10.8% of the patients with PSA between 4 and 10 ng/ml and none of the patients with PSA values below 4 ng/ml. We suggest an antibiotic therapy for 3 weeks without regarding inflammation findings when PSA is in the gray zone, for biopsy decision.

Background : In the present study, we assessed the efficacy and morbidity of periprostatic local anesthesia before transrectal ultrasound (TRUS)-guided biopsy of the prostate.

The study was conducted to investigate the efficacy of Saccharomyces cerevisiae extract (SC) on haematological parameters, immune function, and the antioxidant defence system in breeder hens fed a diet contaminated with low level aflatoxin (AF). Forty-eight Ross 308 breeder hens were fed on diets containing AF (0 or 100 µg/kg) and SC (0 or 1 g/kg) in a 2 × 2 factorial arrangement. Red blood cell (RBC), white blood cell (WBC), and platelet counts, differential leucocyte counts, blood CD3+, CD4+, CD8+ and CD5+ T cell ratios, phagocytic activity and oxidative burst of heterophils, plasma and liver catalase activity, and malondialdehyde (MDA) and ascorbic acid concentrations were measured. 3. Plasma and liver MDA concentrations increased (P < 0·05), liver catalase activity decreased (P < 0·05) and total WBC count tended to decrease (P = 0·082) in hens fed the contaminated diet. WBC count, monocyte percentage, phagocytic activity and oxidative burst of heterophils increased (P < 0·05), and plasma MDA concentration tended to decrease (P = 0.088) in SC extract supplemented hens. There was a significant interaction between AF and SC on heterophil, lymphocyte, CD5+ cell percentages, and plasma catalase activity. Blood heterophil percentage decreased but lymphocyte percentage increased in hens fed on the AF contaminated diet without SC supplementation. SC supplementation counteracted the negative effect of AF on heterophils and lymphocytes. The CD5+ cell percentage decreased in unsupplemented hens fed the AF contaminated diet and this negative effect was minimised in SC supplemented hens. Plasma catalase activity increased in SC supplemented hens fed the uncontaminated diet whereas the effect of SC decreased in hens fed the AF contaminated diet. 4. The SC reduced some of the some adverse effects of AF, and improved functions of the non-specific immune system. Therefore, the SC extract which has been used for improving productive performance in birds and mammals may also be useful for modulating some of the effects of a low level, chronic dosage of AF.

Our data suggests that using either a combination of intrarectal lidocaine gel and periprostatic block or solely unilateral pudendal nerve block for prostate biopsy procedures provides efficient patient comfort by reducing pain both during probe insertion and needle passing through the prostate gland.
