Abstract
Chronic hypoxia is related to many pathological conditions: aging, heart and respiratory failure, sleep apneas, smoke, chronic obstructive pulmonary disease (COPD), diabetes, hypertension and arteriosclerosis, all characterized by reductions of sleep-related erections (SREs) and by erectile dysfunction (ED). Sleep-related erections occur naturally during rapid eye movement (REM) sleep in sexually potent men. Hypoxia is also a physiological condition at altitude. The level of inspired oxygen decreases progressively with the increase of altitude; for this reason, this study was performed to evaluate the relationship of SREs with hypoxic environment. SREs have been recorded by an erectometer (RigiScan) on three mountain climbers (mean age: 32.5) during a 26-day stay at an altitude ranging from 2000 to 5600 m above sea level. Twenty-four records have been made at progressively increasing altitudes. A data analysis was carried out on a statistical mean of the three values of each variable and an analysis of variance (ANOVA) and Newman-Keuls test were carried out for multiple comparison among groups. At altitudes over 4450 m, we found lack of rigidity at 80-100% and 60-79%. Mean % of rigidity and rigidity time of 80-100% (tip and base) decreased progressively with altitude. No significant reductions were shown in rigidity time at 0-19% and at 20-39% (tip and base), of total number, of total and mean duration of SREs. Pathological rigidometric records at high altitude in sexually potent men at sea level clarify the primary role of hypoxia in physiopathological ED pathway.

Abstract
The skeleton is the third most common site for cancer to spread after the liver and lungs. Malignancies that can cause destruction of skeletal bones include multiple myeloma and metastatic diseases of the lung, prostate and other solid cancers. The clinical complications include pain, fractures, compression of the spinal cord and hypercalcemia of malignancy. Bisphosphonates are bone-seeking agents originally designed to treat loss of bone density. Accumulating data show that they are effective in diseases in which there is upregulation of osteoclastic or osteolytic activity. Bisphosphonates can reduce skeletal-related events and bone pain, as well as reduce the adverse effects of androgen deprivation therapy on skeletal integrity. However, it is clear that bisphosphonates do not represent a decisive treatment in the care of metastases but a therapeutic choice in synergy with regular anti-tumor drugs. The preclinical and clinical data to support this are reviewed here.

Abstract
Approximately 70% of the bladder tumors are superficial, and 10%-20% of these progresses as muscle-invasive. For implant problems is common the practice to immediately instill chemotherapeutic agents after TURBT that a decrease of the recurrence has provoked. Many urologists didn't observe any deleterious effect of simultaneous TURBT-TURP. But really the simultaneous approach provokes an increase of the recurrence of the tumor to the bladder neck or prostatic urethra? We have performed a perspective study after simultaneous approach. In our Clinic any case of solitary recidivist is not occurred in the prostatic site, but in all the patients concomitant multiple locations are been observed.

Abstract
Endometriosis functionally causes lesions, nodules or active bulges to numerous organs. Is the second most common pelvic pathology in woman and strikes the 10–20% of the women in the pre-menopausal epoch (40–45 years) and the interest of the urinary apparatus is 1–11%. Rare to renal level, it mostly strikes the bladder and in smaller measure the ureters and the uretera with a relationship 40/5/1. Ureteral location is common extrinsic, deriving for contiguity of the ovarian endometriosis adherent or of the peritoneum or of the uterus-sacred ligament; rare the ureteral intrinsic endometriosis, primitively located in the organ wall. Our therapeutic orientation is surgical, especially in the cases of wide endometriosis or when the tissue has had a cicatrizial involution with absence of answer to the hormonal therapy.

Abstract
Prostate cancer is the most common solid malignancy in men in the United States. As a disease predominantly affecting the elderly and with the continuing aging of the population, the importance of studying and treating prostate cancer will continue to increase. Many factors have been implicated in the development of prostate cancer. It presents a variability of incidences influenced by dietary factors. The administration of substances, such as Lycopene, Polyphenols, Iso-flavonoids, Vitamin D, Vitamin E, Selenium and Zinc have a decisive role in the prevention of anti-apoptotic and pro-angiogenesis processes which are long-term developing properties of cancer cells. In this study, we will provide an overview of the current state of art between dietary habits and risk of prostate cancer.

Abstract
A cDNA from Riftia pachyptila was cloned. It encodes a novel 21.3-kDa protein from the worm protective tube, named RCBP (for Riftia chitin-binding protein). On the basis of partial tube-peptide sequences previously obtained, experiments using reverse transcriptase-mediated polymerase chain reaction and rapid amplification of cDNA ends led to the complete cDNA sequence. Analysis of its deduced amino acid sequence shows the presence of two chitin-binding domains. These domains are closely related to type 2 chitin-binding domains that are restricted to the animal kingdom. We showed by affinity assay and immunogold labeling that RCBP is the first protein so far known that binds specifically beta-chitin and that is unable to bind the most common alpha-form found in chitin secreting animals. The RCBP mRNA was found to be present in specific epidermal cells from the worm body wall, but never in the chitin-secreting gland cells. This unexpected result clearly indicates that this tube protein is synthesized in specialized areas of the outer epithelium and that at least two different tissues are involved in this exoskeleton synthesis.

Abstract
The Peyronie's disease or Induratio Penis Plastica, represents one of the most controversial and uncertain points of the modern andrology, since its real etiology is still disputable. Consequently also the non-surgical therapy results as still confused and variable as shown in the considerable number of drugs utilized till now. Our study takes into consideration the injection therapy, by the use of the Betamethasone (corticosteroid), and it tries to explain, how it is possible, the real efficacy of drug versus placebo. The randomized study includes 30 patients. The valuation of the results has been effected in reference to three parameters: disappearance of pain, decrease of plaque volume and consistency of 50%, decrease subjective penile curvature. The data obtained show no significant differences between group A (treated with Betamethasone) and group B (treated with placebo). At twelve months of mean follow-up the pain at erection disappeared in 66.6% of the patients of group A, in 53.3% of the patients of group B. The curvature diminished in 20% of the patients of group A and in 26.6% of the patients of group B. A decrease in plaque volume and consistency was noted in 40% of the patients of group A and in 40% of the patients of group B. The data show that probably the clinical results of the therapy is to refer to a mechanical effect of injected volume and not to the drug action itself.

Abstract
We evaluated the immune response after BCG treatment in superficial bladder cancer analyzing the modifications induced on lymphocytic sub-populations. In 21 patients with superficial bladder cancer we performed TURB and after 12 days began the induction cycle of 6 weeks with Pasteur BCG (75 mg/50 micromilligrams), followed by one instillation monthly for one year. Before treatment every patients underwent Mantoux intradermoreaction, blood-count and determination of peripheral blood lymphocytic subpopulations. Blood-count and lymphocytic subpopulations were repeated after 1 week, after 6 weeks, after 3 months and after 1 year. During cystoscopy after 3 months every patients underwent vesical biopsy. CD4+ and CD8+ are mainly interested among lymphocytic subpopulations at the beginning: BCG decreased CD4+ value in the patients with complete response and then it increased CD4+ and reversed the ratio between CD4+ and CD8+ on vesical mucosa.

Abstract
Burn injury in children is associated with low bone formation and long-term bone loss. Because recombinant human GH (rHGH) may accelerate burn wound healing, and because rHGH increases bone formation and density in GH-deficient patients, we studied the short-term effects of rHGH on bone fomation, reflected by osteocalcin and type I procollagen propeptide levels in a randomized, double-blind, placebo-controlled study. Nineteen patients were enrolled and received either rHGH (0.2 mg/kg.day) or an equal volume of saline. Mean burn size and age were not different between the groups, and test substances were given from admission to time of wound healing (mean: 43 +/- 22 days). At wound healing, serum levels of insulin-like growth factor (IGF)-1 and IGF binding protein (IGFBP)-3 in the rHGH group rose to mean values of 229% and 187% of the respective means of the placebo group (P < 0.025). Serum osteocalcin concentrations remained below normal in both groups, and type I procollagen propeptide levels achieved a low normal level IGFBR-4 levels were twice that of normal on admission and doubled further at wound healing; IGFBP-5 levels were low on admission but rose to normal at wound healing. We conclude that large doses of rHGH were ineffective in improving disordered bone formation despite increasing serum IGF-1 and IGFBP-3. The rHGH-independent rise in serum levels of the inhibitory binding protein IGFBP-4 suggests a mechanism by which improved bone formation is prevented despite successful elevation of IGF-1 and IGFBP-3 in the burned child.

Abstract
Y chromosome molecular analysis was performed using the STS-PCR technique in 50 patients with oligozoospermia. Microdeletions of interval 6 of the Y chromosome were detected in seven patients, in six of whom subinterval E was affected. All patients retained the RBM1 and DAZ genes, while in one deletion involved the SPGY gene. The size of the deletion was not apparently related to the severity of the disease. These results suggest the presence of an oligozoospermia critical region on the Y chromosome within subinterval E of interval 6.

Abstract
The orthotopic ileal neobladder is a completely detubularized, low pressure, high capacity reservoir created from the ileum without any valve. After cystoprostatectomy, a bowel segment of 40-60 cms is dissected free at a distance of 15 cms from the ileo-cecal valve. The bowel is detubularized and configurated in a cylinder. Then the neobladder is anatomized to the urethra and ureters. From 1989 to 1995 20 patients underwent ileal orthotopic urinary diversion according to Hautmann. Two patients died, the others are still disease free (mean follow up 36 months). The high capacity and low pressure allow a good continence control, while among metabolic alterations the most frequent is metabolic acidosis. The ileal neobladder represents a valid alternative to any form of cutaneous urinary diversion and is associated to a low incidence of complications.

Abstract
OBJECTIVE To determine the cause and extent of hypocalcemia observed in children after severe burns. DESIGN We studied 10 children with burns covering 57% +/- 17% (SD) body surface area, ages 9.6 +/- 4.7 years, who were admitted consecutively during a 6-month period. Diet supplied a minimum of 2.7 gm/m2 of calcium, 0.3 gm/m2 of magnesium, and 2.2 gm/m2 phosphate. Blood specimens were obtained daily for 10 +/- 5 days for the following tests: (1) simultaneous analysis for ionized calcium, magnesium, and intact parathyroid hormone (group A); (2) two of these children, randomly selected, had serial 2-hour determinations on a single day (group B); (3) a modified Ellsworth-Howard test, consisting of a 10-minute infusion of synthetic parathyroid hormone 18 +/- 10 days post-burn and associated changes in urinary cyclic adenosine monophosphate excretion and renal threshold phosphate concentration (group C). Three of these children, when normomagnesemic, also received a standard magnesium infusion to determine magnesium retention (group D). Data were analyzed with chi-square, regression analysis, and non-parametric testing as appropriate. RESULTS All patients showed sustained hypocalcemia and hypomagnesemia; intact parathyroid hormone response was inappropriately low and response to synthetic parathyroid hormone infusion was blunted. Lowest ionized calcium levels were associated with hypomagnesemia. CONCLUSION Hypoparathyroidism and blunted renal response to parathyroid hormone suggest that magnesium depletion may contribute to their pathogenesis. Magnesium repletion and monitoring are recommended.

Abstract
Mechanism by which intravesical BCG treatment mediates antitumor activity are currently poorly understood. We initiated studies to determine the sequence and the factors that produce the immunological events. During the inflammatory answer a lot of molecules are produced. Chemokines MCP-1 and RANTES induces the mast-cell recruitment, that begins the "immunological fall". In our study 5 patients with superficial bladder cancer treated with BCG present an improvement of this cytokines correlated with a tumor-free status.

Abstract
BCG has been shown in prospective randomized clinical trials to provide superior therapeutic results when composed to transurethral resection alone, or to adjuvant therapy with Thiotepa or Adriamicin. Even if the mechanism by which BCG mediate antitumor activity are not clearly established, an association between the immunological response and antitumoral activity is known IL-1 and TNF alfa are the monokines that have multiple biological effects, including linfocyte proliferation, production of fever, augmentation of cytotoxicity and production of cytokines. The goal of this study is show the response from LPS induced and not peripheral monocytes of superficial bladder cancer patients BCG treated and not, i.e. the levels of TNF alfa, IL-1 and not IL-6.

Abstract
This study presents the use and effects of a low mineral content water called "Monteferrante" on patients with urinary stone disease. We evaluated the blood and urine sample of twenty stone formers and ten healthy volunteers at three and six months after "Monferrante" water intake. Besides a benefic increasing of diuresis, the results show: an increase of: urinary magnesium (p < 0.001), urinary calcium (p < 0.01), uricosuria (p < 0.01), and reduction of: blood uric acid (p < 0.01), blood sodium (p < 0.05), azotemia (p < 0.05) and cholesteremia (p < 0.01). The "Monferrante" oligomineral water can be considered as an efficacy presidium in the prevention of stone disease.

Abstract
PSA half-life was calculated in 37 patients after radical prostatectomy to identify earlier patients with residual disease. The half-life calculated in patients potentially "cured" with absolute PSA values inferior to 0.5 ng/ml after 28 days, was significantly different (P = 0.0008) from the group of patients "uncured" (PSA > 1.0 ng/ml) and from those ones that, despite of detectable PSA level, had evidence of recurrence in the following follow-up. In comparison with the absolute value, the PSA half-life is able to define in the group of patients potentially "cured" those who could have a recurrence in the future.

Abstract
A retrospective clinical study was carried out to compare results obtained with just endoscopic resection and with adjuvant use of the Bacillus Calmette-Guérin (BCG), epirubicin and mitomycin C after TURB in patients with superficial bladder tumour (stage pTa/1 grade 1-3). At an average follow-up of 44 months, a decrease in the percentage of recurrences was noted in all the adjuvant therapy groups compared to that in the group subjected to TURB only. The risk of recurrence for the BCG group was 0.427, for the epirubicin group 0.609 and for the mitomycin C group 0.668. There was progression of the disease in: 5.6% of the TURB, 9.1% of the BCG, 5% epirubicin and 3.6% mitomycin C, for a total of 26 patients (7.3%). Twenty-four cystectomies were performed and 2 patients died due to progression of the disease. At 44 months average follow-up, 353 (98.6%) patients are alive and 329 (93.2%) still have their own bladder.

Abstract
Spinocellular carcinoma of the penis is rare and potentially fatal, especially when there are lymph node metastases. From January 1992 to December 1995 we treated 6 stage T3 N1 M0 tumours of the penis. Six to eight weeks after total penectomy, bilateral inguinal lymphadenectomy and pelvic lymphadenectomy were carried out. These patients also underwent 8 cycles of chemotherapy with vincristine, bleomycin and methotrexate. At an average follow-up of 36 months, all the patients are disease-free with no signs of recurrence either in the lymph nodes or in any organ.

Abstract
Hemospermia is a common benign condition, but is prevalence remains unknown, and can result from several causes. The etiology is idiopathic in about 50% of cases. The advent of transrectal ultrasonography has afforded the opportunity to best evaluate patients with hemospermia. Eighty patients affected by hemospermia were studied with Stamey test, semen analysis and culture, and transrectal ultrasonography (TRUS). Infection was detected in 16/80 of the cases (20%), while in 11/80 patients (14%) was present only excessive white blood cells in expressed prostatic secretions. TRUS showed abnormalities in 70/80 of patients (88%), including periurethral and ejaculatory calculi (42/70 pt., 60%), dilated seminal vesicles (22/70 pt., 31.4%) and müllerian duct cyst (6/70 pt., 8.6%). Stamey test and TRUS are the more usefulness investigations in hemospermia, since they can demonstrate the pathologic causes in about 90% of the cases.

Abstract
Prostatitis syndromes are frequent and cause pain and discomfort in adult males. Non bacterial types occur more often than bacterial prostatitis. Transrectal ultrasound permits a perfect evaluation of prostate, seminal vesicles and ejaculatory ducts. Fifty-five patients affected by prostatis syndrome and with negative bacteriological studies, underwent transrectal ultrasonography performed with 7.5 MHz probe. In 38 cases (70%) we found abnormalities such as subacute vesiculitis, asymmetric dilation of the seminal vesicle, dilated and calcific ejaculatory ducts, mullerian duct cyst, utricular cyst and calcification. Ultrasonography is able to detect these lesions that often are responsible of the clinical symptom of the prostatitis syndrome, and may have a therapeutic value through guided transperineal needle aspiration or in the planning specific endoscopic surgery.

Abstract
Clinical examination and ultrasonography are often the only evaluation needed for patient with Peyronie's disease. Magnetic resonance angiography (MRA), a new magnetic resonance imaging (MRI), improves tissue contrast between the fibrous plaque and the near structures. A total of 25 patients with Peyronie's disease underwent palpation, ultrasonography and MRI after dynamic improvement with intrapenile 10 micrograms prostaglandin E1. The patients were studied with conventional ultrasonography (US) (7.5 MHz) and with 1.5 T superconductive magnet (two-dimensional Fourier transform gradient-echo time-of-flight, 2DFT-TOF, sequences and conventional T1 and T2 spin echo (SE) sequences). The US evaluation demonstrated the presence of plaques in 18/25 patients (72%). The SE sequences revealed evidence of plaques in 10/25 patients (40%). MR angiograph enabled the correct evaluation of plaques in 23/25 patients (92%), and identified the involvement of the septum intercavernosum, that was not detected on both US and SE images. MRA provides accurate preoperative information fo correct evaluation of plaque extension in IPP.

Abstract
Von Hippel-Lindau (VHL) disease is a genetic disorder characterized by hemangioblastomas of the brain and spinal cord, retinal angiomas, pancreatic cysts, pheochromocytomas, epididymal cystadenomas and renal cysts and neoplasms. These disease is transmitted in an autosomal dominant fashion and the gene associated with transmission of VHL has been localized to the 3p25-3p26 region of chromosome 3. In this study we examined a family with von Hippel-Lindau disease established of mother and three children and five progeny. These patients were evaluated with urinary tract echography, computerized tomography, DNA sequencing with polymerase chain reactions (PCR) and SSCP analysis. The ultrasonography is utilized to diagnosis, screening and in the follow-up of undergone surgery patient's. With this study we examined the role of echography in patients with von Hippel-Lindau disease.

Abstract
There are two type of congenital prostatic cyst, the müllerian duct cyst and the utricular cyst. They are not common and rarely symptomatic. We report a 16-year-old male who presented with acute urinary retention and a 3-month history of urine stream diminished in force and reduced sperm volume. Transrectal ultrasonography showed a prostatic cyst in the midline near the seminal colliculus. Transperineal aspiration of the cyst resulted in return to normal miction and sperm volume.
