Abstract
Since the industrial revolution, all living beings have become susceptible to numerous sources of aluminum (Al) exposure. In addition to causing proven toxicity in many organs and systems, Al can also have estrogenic activity when absorbed by the body. The reproductive organs are commonly affected by environmental pollutants with estrogenic activity, but little is known about the effects of Al on the prostate and gonads. Therefore, the aim of this study was to evaluate the effects of subchronic Al exposure on the prostate and gonads of male and female adult gerbils. After 30 days of oral exposure to aluminum chloride (10 mg/kg/day), the animals were euthanized and the organs processed for cytochemical, ultrastructural, and biochemical assays. Ventral male prostates exposed to Al became hyperplastic and showed signs of cell aging. In addition, the male prostate showed decreased catalase (CAT) and superoxide dismutase (SOD) activity. The female prostate was structurally more affected than the ventral male prostate, since it presented hyperplasia and punctual foci of inflammation and prostatic intraepithelial neoplasia. However, CAT and SOD activities did not change in this gland. In the testis, Al promoted immature germ cell detachment and degeneration, as well as reduced CAT activity. In the ovaries, Al caused reduction in folliculogenesis and decreased SOD activity. Together, these results indicate that Al is toxic to the prostate and gonads of adult gerbils and that continuous exposure to this metal can impair the fertility of individuals of both sexes.

Abstract
BACKGROUND AND OBJECTIVES Enhancer of zeste homolog 2 (EZH2) has been recently found to regulate several genes involved in immunoresponse and autocrine inflammation network. The aim of the study was to quantitate EZH2 messenger ribonucleic acid (mRNA) expression, evaluate its relation to conditions of prostatitis associated with benign prostatic hyperplasia (BPH), and correlate it with the levels of the inflammatory marker interlukin 6 (IL-6). DESIGN AND SETTING Cross-sectional study in Middle Eastern men with BPH and prostatitis or BPH only. PATIENTS AND METHODS Transrectal ultrasound-guided prostate biopsies were collected from 106 patients suspected of having prostate cancer; however, the histology revealed BPH. Upon further pathological examination, 56 of these cases were identified as BPH with prostatitis and classified as: acute prostatitis (n=13); active chronic prostatitis (n=32); and, chronic inactive prostatitis (n=12). Serum IL-6 levels and EZH2 mRNA expression were measured and compared between patient groups. RESULTS EZH2 mRNA was overexpressed in BPH with prostatitis patients compared to BPH only patients (P<.0001). BPH with active chronic prostatitis had higher EZH2 expression than BPH with acute or chronic inactive prostatitis compared to BPH only (P=.05 and .73, respectively). EZH2 mRNA expression showed a negative correlation with IL-6 concentrations in BPH with prostatitis patients (rs=-0.31, P=.02). EZH2 overexpression was associated with an increased risk of having BPH with prostatitis (crude odds ratio 0.20, 95% CI 0.06-0.65, P=.0076). CONCLUSIONS EZH2 mRNA expression correlates positively with prostatitis conditions associated with BPH and negatively with serum IL-6 levels. This supports the possible involvement of EZH2 mRNA overexpression in the development of prostate inflammation, and its new regulatory role in suppressing the expression of some inflammatory network genes.

Abstract
The detrimental effect of chronic chromium (Cr) exposure on the prostate has never been studied. Here, we report the prostate specific antigen (PSA) changes in occupational chromate exposed workers. In this study, eighty six male occupational chromate exposed workers and forty five age-matched controls were recruited. The concentration of Cr in urine (U-Cr), serum total PSA (tPSA), free PSA (fPSA), high sensitive C reactive protein (Hs-CRP) and peripheral white blood cells count (WBC) were measured. The results show that the U-Cr, serum tPSA, Hs-CRP and WBC were significantly higher in Cr exposed workers when compared to the controls. Contrastively, the serum fPSA level in Cr exposed workers was lower than controls. A significant positive correlation between U-Cr and serum tPSA was observed. Multiple linear regression analysis revealed that serum tPSA and fPSA level was statistically associated with the serum Hs-CRP and U-Cr concentration in Cr exposed workers. These observations suggested that chronic Cr exposure could produce potential prostate injury and the nonspecific inflammation at least might be one of the reasons to explain the elevated concentration of tPSA in chronic occupational chromate exposed workers.

Abstract
AIM To evaluate the outcome of prostate cancer patients with initial PSA value >40 ng/ml. BACKGROUND The outcome of prostate cancer patients with very high initial PSA value is not known and patients are frequently treated with palliative intent. We analyzed the outcome of radical combined hormonal treatment and radiotherapy in prostate cancer patients with initial PSA value >40 ng/ml. METHODS Between January 2003 and December 2007 we treated, with curative intent, 56 patients with non-metastatic prostate cancer and initial PSA value >40 ng/ml. The treatment consisted of two months of neoadjuvant hormonal treatment (LHRH analog), radical radiotherapy (68-78 Gy, conformal technique) and an optional two-year adjuvant hormonal treatment. RESULTS The median time of follow up was 61 months. 5-Year overall survival was 90%. 5-Year biochemical disease free survival was 62%. T stage, Gleason score, PSA value, and radiotherapy dose did not significantly influence the outcome. Late genitourinal and gastrointestinal toxicity was acceptable. CONCLUSION Radical treatment in combination with hormonal treatment and radiotherapy can be recommended for this subgroup of prostate cancer patients with good performance status and life expectancy.

Abstract
Calcification, a phenomenon often regarded by pathologists little more than evidence of cell death, is becoming recognized to be important in the dynamics of a variety of diseases from which millions of beings suffer in all ages. In calcification, all that is needed for crystal formation to start is nidi (nuclei) and an environment of available dissolved components at or near saturation concentrations, along with the absence of inhibitors for crystal formation. Calcifying nanoparticles (CNP) are the first calcium phosphate mineral containing particles isolated from human blood and were detected in numerous pathologic calcification related diseases. Controversy and critical role of CNP as nidi and triggering factor in human pathologic calcification are discussed.

Abstract
Inflammation is a common finding in histologic prostate specimens obtained from aging men, and accumulating data suggest that inflammation may play an important role in the development of benign prostatic hyperplasia (BPH), and the development and progression of lower urinary tract symptoms (LUTS). Inflammatory processes may contribute to prostatic enlargement directly through stimulation of prostate growth, or, alternatively, through decreasing prostatic apoptosis. Additionally, inflammatory processes may impact other components of the urogenital tract, such as the bladder, and contribute to the LUTS that may be experienced both in the presence and in the absence of prostate enlargement. Current research therefore offers clues about converging inflammatory pathways which may be targeted to improve treatment of BPH and/or LUTS as well as identifying potential targets for prevention of these syndromes.

Abstract
OBJECTIVE To investigate the influence of subclinical or histologically diagnosed prostatitis on serum prostate-specific antigen (PSA) in patients investigated for prostatic disease in Kuwait. MATERIALS AND METHODS Serum PSA was assayed in patients investigated for prostatic disease in Mubarak Al-Kabeer Hospital, Kuwait, between December 2002 and December 2004. These included patients undergoing transrectal ultrasound with needle biopsy of the prostate gland and those who were treated with transurethral resection of the prostate or retropubic prostatectomy. The tissue was evaluated for prostatitis as well as the underlying disease, and the type and severity of prostatitis were compared with levels of serum PSA. RESULTS Of the 331 tissue specimens, 18 (5.4%) did not show prostatitis, while 233 (70.4%) with benign prostate and 80 (24.2%) with malignant prostate disease showed prostatitis. Of 270 men with known serum PSA levels, 198 and 72 had benign and malignant prostate disease, respectively. Of the 198, 77 (41%) with benign prostate disease and prostatitis and of the 72, 52 (76%) with malignant prostate disease and prostatitis had serum PSA levels >10 ng/ml. CONCLUSION The data showed that although raised serum PSA is more commonly associated with prostate cancer, subclinical prostatitis is a significant source of high serum PSA in over 40% of men in Kuwait. That local factors may obscure the usefulness of serum PSA as a screening tool suggests the need for a locally applicable paradigm to identify prostate cancer.

Abstract
INTRODUCTION Asymptomatic inflammatory prostatitis is a common pathological finding in patients with benign prostatic hyperplasia (BPH). In the present study, we evaluated the correlation between serum prostate specific antigen (PSA) level and extent and aggressiveness of inflammation in surgical specimens of patients who underwent to surgery for BPH without any evidence of clinical prostatitis. METHODS Histological sections of the prostatic tissues of 52 patients were scored for the extent of inflammation and aggressiveness of inflammation, using the four point scale designed by Irani et al. Extent of inflammation is graded from 0 to 3 according to the degree of invasion of inflammatory cells in prostate tissue. Aggressiveness of inflammation is graded from 0 to 3 according to the degree of contact or disruption of prostatic glandular epithelium by inflammatory cells. The serum PSA levels in different inflammation grades were compared. RESULTS There was a significant correlation between inflammation and aggressiveness scores (r = 0.39, P < 0.01). Median PSA levels in grades 1, 2 and 3 extent of inflammation were 2.4, 5.2 and 5.7 ng/ml, respectively. There was not any significant difference between these grades for PSA. Furthermore, median PSA levels in grades 1, 2 and 3 aggressiveness of inflammation were 4.4, 4.8 and 8.7 ng/ml, respectively. There was a significant difference between grades of aggressiveness of inflammation and PSA levels. CONCLUSION High serum PSA levels may correlate with asymptomatic inflammatory prostatitis with high aggressiveness score in BPH patients without clinical prostatitis.
