Unrecognized for centuries: distribution and sexual caste descriptions of the West European Aphaenogaster species of the subterranea group (Hymenoptera, Formicidae). Zookeys 2023; 1153:141-156.

Abstract
There are only two Aphaenogaster species from the subterranea group in the western Mediterranean: A. ichnusa Santschi, 1925, from south-western Europe, and A. subterranea (Latreille, 1798), also occurring in central and eastern Europe. Historically, the two species have been widely misunderstood: A. ichnusa was long considered a Sardinian endemic subspecies of A. subterranea, while its continental populations were misidentified as A. subterranea s. str. Recently, A. ichnusa was elevated to species rank and its worker caste was redescribed with that of A. subterranea, allowing for their correct identification. Yet their distribution was documented in detail only for France and Sardinia. Furthermore, no morphological characters were described to distinguish the males and queens of the two species. By investigating private and museum collections, 276 new records of A. ichnusa are provided here and 154 of A. subterranea from the western Mediterranean. Additionally, qualitative and quantitative morphological characters were combined to identify their males and queens. We present the new southernmost, easternmost, and westernmost distribution limits for A. ichnusa. Based on our results, this species is widely distributed in Italy and Catalonia (Spain), also occurring on several Mediterranean islands, avoiding areas with continental climate and high altitudes. Sicily is the only island to host the less thermophilous A. subterranea, which otherwise extends westward to Galicia (Spain). Sympatric occurrence is not rare along the contact zone. Additional natural history observations are reported regarding foraging habits, associated myrmecophiles, habitat preferences, and colony structure in the two species.

Abstract
The OPERA experiment was designed to discover the vτ appearance in a vμ beam, due to neutrino oscillations. The detector, located in the underground Gran Sasso Laboratory, consisted of a nuclear photographic emulsion/lead target with a mass of about 1.25 kt, complemented by electronic detectors. It was exposed from 2008 to 2012 to the CNGS beam: an almost pure vμ beam with a baseline of 730 km, collecting a total of 1.8·1020 protons on target. The OPERA Collaboration eventually assessed the discovery of vμ→vτ oscillations with a statistical significance of 6.1 σ by observing ten vτ CC interaction candidates. These events have been published on the Open Data Portal at CERN. This paper provides a detailed description of the vτ data sample to make it usable by the whole community.

Abstract
Prostate cancer, a leading cause of cancer-related deaths worldwide, principally occurs in over 50-year-old men. Nowadays there is urgency to discover biomarkers alternative to prostate-specific antigen, as it cannot discriminate patients with benign prostatic hyperplasia from clinically significant forms of prostatic cancer. In the present paper, 32 benign prostatic hyperplasia and 41 prostatic cancer urine samples were collected and analyzed. Polar and positively charged metabolites were therein investigated using an analytical platform comprising an up to 40-fold analyte enrichment step by graphitized carbon black solid-phase extraction, HILIC separation, and untargeted high-resolution mass spectrometry analysis. These classes of compounds are often neglected in common metabolomics experiments even though previous studies reported their significance in cancer biomarker discovery. The complex metabolomics big datasets, generated by the UHPLC-HRMS, were analyzed with the ROIMCR procedure, based on the selection of the MS regions of interest data and their analysis by the Multivariate Curve-Resolution Alternating Least Squares chemometrics method. This approach allowed the resolution and tentative identification of the metabolites differentially expressed by the two data sets. Among these, amino acids and carnitine derivatives were tentatively identified highlighting the importance of the proposed methodology for cancer biomarker research.

Abstract
Limited attention has been given to the psychological impact of primary treatments in patients with prostate cancer. Aim of our analysis was to critically analyse the current evidence on the psychological impact of different primary treatments (surgery, radiotherapy and active surveillance), in patients with prostate cancer, using validated questionnaires. We searched in the MEDLINE and Cochrane library database from the literature of the past 15 years (primary fields: prostate neoplasm, AND radical prostatectomy or radiotherapy or active surveillance AND psychological distress or anxiety or depression; secondary fields: urinary, sexual, bowel modifications, non-randomised and randomised trials). Overall eighteen original and review articles were included and critically evaluated. Either radical prostatectomy or active surveillance and radiotherapy are well-tolerated in terms of definite anxiety and depression during the post-treatment follow-up. A mutual influence between functional and psychological modifications induced by treatments has been demonstrated. Urinary symptoms related to incontinence more than sexual and bowel dysfunction are able to induce psychological distress worsening. In conclusion, patients and their clinicians might wish to know how functional and psychological aspects may differently be influenced by treatment choice.

Abstract
The OPERA experiment was designed to study ν_{μ}→ν_{τ} oscillations in the appearance mode in the CERN to Gran Sasso Neutrino beam (CNGS). In this Letter, we report the final analysis of the full data sample collected between 2008 and 2012, corresponding to 17.97×10^{19} protons on target. Selection criteria looser than in previous analyses have produced ten ν_{τ} candidate events, thus reducing the statistical uncertainty in the measurement of the oscillation parameters and of ν_{τ} properties. A multivariate approach for event identification has been applied to the candidate events and the discovery of ν_{τ} appearance is confirmed with an improved significance level of 6.1σ. |Δm_{32}^{2}| has been measured, in appearance mode, with an accuracy of 20%. The measurement of the ν_{τ} charged-current cross section, for the first time with a negligible contamination from ν[over ¯]_{τ}, and the first direct evidence for the ν_{τ} lepton number are also reported.

Abstract
Our study is aimed at evaluating the presence of p53 and Ki67 expression by immunohistochemistry in a series of 11 paraffin-embedded penile carcinomas. We also investigated the presence of Human Papillomavirus (HPV) DNA in these tumours and performed an accurate typing by DNA sequencing on positive samples. Immunohistochemistry (IHC) was performed with the anti-p53 and Ki67 mouse monoclonal antibodies. DNA extracted from small sections of each specimen was submitted to amplification with HPV specific general primers; PCR products of the proper length were purified and sequenced. IHC demonstrated nuclear accumulation of mutated p53 and Ki 67 expression in 10/11 tumour samples (90.9%). The prevalence of HPV DNA was 72.7%; the most prevalent type was HPV16. Sequencing analysis revealed the presence of HPV53 (12.5%), HPV18 (25%) and HPV16 (62.5%). Out of the p53 or Ki67 positive carcinomas the percentage of HPV positives was 80% and 70% respectively. Our results indicate that penile carcinoma is frequently associated to high risk HPV and with diffuse p53 and Ki67 expression.

Abstract
Since sperm require high energy levels to perform their specialised function, it is vital that essential nutrients are available for spermatozoa when they develop, capacitate and acquire motility. However, they are vulnerable to a lack of energy and excess amounts of reactive oxygen species, which can impair sperm function, lead to immotility, acrosomal reaction impairment, DNA fragmentation and cell death. This monocentric, randomised, double-blind, placebo-controlled trial investigated the effect of 6 months of supplementation with l-carnitine, acetyl-l-carnitine and other micronutrients on sperm quality in 104 subjects with oligo- and/or astheno- and/or teratozoospermia with or without varicocele. In 94 patients who completed the study, sperm concentration was significantly increased in supplemented patients compared to the placebo (p = .0186). Total sperm count also increased significantly (p = .0117) in the supplemented group as compared to the placebo group. Both, progressive and total motility were higher in supplemented patients (p = .0088 and p = .0120, respectively). Although pregnancy rate was not an endpoint of the study, of the 12 pregnancies that occurred during the follow-up, 10 were reported in the supplementation group. In general, all these changes were more evident in varicocele patients. In conclusion, supplementation with metabolic and antioxidant compounds could be efficacious when included in strategies to improve fertility.

Abstract
This is an open, multicentre, randomized, crossover study having the aim to evaluate the preference for sildenafil citrate or tadalafil in a population of Italian patients affected by ED, and to compare the efficacy and safety of these two drugs. Material and Methods. From October 2003 to November 2004, thirteen Italian centers enrolled ED patients (age >18) being in steady and naïve relation to ED treatment, both through PDE5 inhibitors and any other treatment option. These patients were randomized to sildenafil or tadalafil for 12 weeks, after which they were switched to the alternative treatment for a further 12 weeks. The preference was evaluated through the Treatment Preference Question (TPQ): “During this clinical trial you have taken tadalafil and sildenafil for the treatment of erectile dysfunction. Which medication do you prefer to take for the next 8 weeks of treatment?”. Moreover, patients were asked to express their preference as “strong” or “moderate” and to answer some questions to clarify the reasons behind their preference. SEP and IIEF-EF questionnaires were used for a comparison of efficacy. Results. 167 patients were enrolled, 144 of whom completed both treatment periods. On being asked the TPQ, 75% of patients (n=108) decided to continue treatment with tadalafil, in particular because it made it possible to have an erection many hours after taking the medication (first or second preference reason for 64.8% of patients), while 25% (n=36) preferred sildenafil (p=0.001). Both drugs improved the IIEF-EF and SEP scores compared to baseline, with a slightly but significantly greater improvement with tadalafil for both parameters. Conclusions. Tadalafil and sildenafil are both effective and well tolerated. Most of the patients prefer tadalafil thanks to the possibility of having sexual intercourse many hours after taking the medication.

Prognostic value of inflammation in prostate cancer progression and response to therapeutic: a critical review. J Inflamm (Lond) 2016; 13:35.

Abstract
Prostate is an immune-competent organ normally populated by inflammatory cells. Prostatic inflammation origin can be multi-factorial and there are some emerging evidences on its possible role as a factor involved in prostate cancer (PC) pathogenesis and progression. This review critically analyzes the role of inflammation as a prognostic factor for progression and aggressiveness of PC. We verified the last 10 years literature data on the association between inflammation and PC aggressiveness, or PC response to therapies. Several studies tried to correlate different inflammatory factors with the aggressiveness and metastatization of PC; all data sustain the role of inflammation in PC progression but they also produce confusion to identify a reliable clinical prognostic marker. Data on patients submitted to radical prostatectomy (RP) showed that cases with marked intraprostatic tissue inflammation are associated with higher rate of biochemical progression; systemic inflammation markers appear to have a significant prognostic value. Analyzing data on patients submitted to radiotherapy (RT) emerges a significant association between high neuthrophil to lymphocyte ratio (NLR) and decreased progression free survival and overall survival; also plateled to lymphocyte ratio (PLR) and C-reactive protein (CRP) have been proposed as significant prognostic factors for progression and overall survival. In patients submitted to androgen deprivation therapy (ADT), inflammation may drive castration resistant PC (CRPC) development by activation of STAT3 in PC cells. NLR has been proposed as independent predictor of overall survival in CRPC submitted to chemotherapy. Most of data are focused on markers related to systemic inflammation such as NLR and CRP, more than specifically to chronic prostatic inflammation. The suggestion is that these inflammatory parameters, also if not specific for prostatic inflammation and possibly influenced by several factors other than PC, can integrate with established prognostic factors.

Abstract
Our aim was to systematically evaluate the benefits of degarelix as antagonist versus agonists of gonadotropin-releasing hormones (GnRH) for the treatment of advanced prostate cancer (PC). This comparison was performed either in terms of biochemical or oncological or safety profiles. To this end we, carried out a systematic review and meta-analysis of the literature.We selected only studies directly and prospectively analyzing the two treatments in the same population (randomized phase III studies). We followed the Preferred Reporting Items for Systematic Reviews and meta-analyses process for reporting studies.After we eliminated studies according to the exclusion criteria, 9 publications were considered relevant to this review. These articles described 5 clinical trials that were eligible for inclusion. The follow-up duration in all trials did not exceed 364 days. This meta-analysis and review comprised a total of 1719 men, 1061 randomized to degarelix versus 658 to GnRH agonists treatment for advanced PC. Oncological results were evaluated only in 1 trial (CS21:408 cases) and they were not the primary endpoints of the study. Treatment emerging adverse events were reported in 61.4% and 58.8% of patients in the degarelix and GnRH agonists group, respectively (odds ratio, OR = 1.17; 95% confidence interval, 95% CI: 0.78-1.77, P > 0.1). Treatment related severe cardiovascular side effects were reported (trial CS21-30-35) in 1.6% and 3.6% of patients in the degarelix and GnRH agonists group, respectively (OR = 0.55, 95% CI: 0.26-1.14, P > 0.1).Our analysis evidences relevant limitations in particular for the comparative evaluation of the efficacy and the oncological results related to degarelix.

Abstract
Erectile dysfunction, the most common male sexual disorder after premature ejaculation, with its important impact on man and partner’s sexuality and quality of life is a persistent inability to obtain and maintain an erection sufficient to permit satisfactory sexual performance. Non-surgical treatments with controversial results are usually applyed before surgical treatment that has reached high levels of satisfaction. We describe a new surgical technique to implant three-pieces penile prosthesis in patients suffering from erectile dysfunction (ED) not responding to conventional medical therapy or reporting side effects with such a therapy. Implantation of an inflatable prosthesis, for treatment of ED, is a safe and efficacious approach with high satisfaction reported by patients and partners. Surgical technique should be minimally invasive and latest technology equipment should be implanted in order to decrease common complications and to obtain a better aesthetic result.

Abstract
Erectile dysfunction (ED) is inability to achieve and maintain an erection to permit satisfactory sexual activity. Homocysteine (Hcys) is a sulfur-containing amino acid synthesized from the essential amino acid methionine. Experimental models have elucidated the role of hyperhomocysteinemia (HHcys) as a strong and independent predictor for atherosclerosis progression and impaired cavernosal perfusion. The aim of this study is to investigate the serum levels of Hcys in our cohort of patients with ED, to compare these values with these of control population and to examine Hcys as a predictive marker for those patients who are beginning to complain mild-moderate ED. A total of 431 patients were enrolled in the study. The whole cohort was asked to complete the International Index of Erectile Function (IIEF) questionnaire. The study population was divided in 3 main groups: Group A: 145 patients with no ED serving as a control group; Group B: 145 patients with mild or mild-moderate ED; Group C: 141 patients with moderate or severe ED. Each participant underwent blood analysis. All patients underwent baseline and dynamic penile Doppler ultrasonography. We found in our cohort mean Hcys plasma concentrations significantly higher than the cut-off point in both groups B and C (18.6 ± 4.7 and 28.38 ± 7.8, respectively). Mean IIEF score was 27.9 ± 1.39, 19.5 ± 2.6, and 11.1 ± 2.5 for groups A, B, and C, respectively (P < 0.0001). In the penile Doppler ultrasonography studies, a high significant inverse correlation was detected between the mean values of the 10th minute's peak-systolic velocity (PSV) and Hcys levels for the groups B and C. This establishes a dose-dependent association between Hcys and ED. Furthermore, we showed that Hcys was an earlier predictor of ED than Doppler studies, as the Hcys increase was present in patients with mild ED even before abnormal Doppler values.

Abstract
BACKGROUND Prostate cancer (PC) represents the most frequently diagnosed cancer in men. Exposure to infectious agents has been considered to induce prostatic inflammation and cancerous transformation. Controversial data exist concerning the role of the human polyomaviruses BK (BKV) and JC (JCV) in PC etiology. Therefore, a possible association between these polyomaviruses and PC was investigated. MATERIALS AND METHODS Urine, blood and fresh prostatic tissue specimens were collected from 26 patients with PC. The presence of BKV and JCV, the possible non-coding control region (NCCR) variations and the genotyping analysis of viral protein 1 (VP1) of both viruses were assessed. RESULTS Data showed a preferential viral re-activation in the urinary compartment and a statistically significant prevalence of JC viruria and of BKV in PC tissues. A BKV DDP-like NCCR sequence was isolated in two patients, whereas JCV NCCR was consistently of an archetypal structural organization. A prevalence of the European genotypes was observed for both viruses. CONCLUSION Our data demonstrated the presence of JCV DNA in 14/24 (58.3%) cancerous prostatic tissue specimens, confirming the results obtained in a previous study, in which JCV has been defined as common inhabitant of the prostate, and opening the discussion about its potential role in PC.

Abstract
BACKGROUND Prostate cancer (PC) is a common tumor in Western countries. Several risk factors play significant roles. MYC, BIRC5/survivin, CDC25 and P53 may contribute to PC risk. As demonstrated, human Polyomavirus BK (BKV) could affect cellular homeostasis contributing to PC pathogenesis. MATERIALS AND METHODS Biological samples were collected from PC patients. Viral RNA was searched using quantitative polymerase chain reaction (PCR), whereas a qualitative PCR was employed to find particular viral sequences. Proper size amplicons were analyzed. Single nucleotide polymorphisms (SNPs) were detected in p53 coding regions by means of a specific PCR. C-MYC, BIRC5/survivin and CDC25 gene expression was investigated using a Retro Transcriptional Quantitative PCR. RESULTS Viral DNA copy number was higher in cancer tissues taken from Gleason score 9 patients with Gleason score 7. Different p53 mutated compared to patients exons were found according to tumor advanced stage and a statistical significant correlation was found between Gleason score and p53 mutational rate. C-MYC, BIRC5/survivin and CDC25 expression was de-regulated according to the literature. CONCLUSION The presence of BKV and its variants in transformed cells does not exclude viral pressure in cell immortalization. Expression of other target genes evidenced a significant change in their regulation, useful for cancer drug discovery and therapies.

Abstract
OBJECTIVE To investigate if short-term treatment with dutasteride (8 weeks) before bipolar transurethral resection of the prostate (B-TURP) can reduce intraoperative bleeding, as dutasteride a dual 5α-reductase inhibitor (5-ARI) blocks the conversion of testosterone into its active form dihydrotestosterone (DHT), and reduces prostate volume and prostate-specific antigen (PSA) levels, while increasing urinary flow rate. PATIENTS AND METHODS In all, 259 patients were enrolled and randomised to two groups: Group A, receiving placebo and Group B, receiving dutasteride (0.5 mg daily for 8 weeks). Blood samples were taken before and after B-TURP for serum chemistry evaluation. In particular we evaluated blood parameters associated with blood loss [haemoglobin (Hb) and haematocrit (Ht)] and prostate vascularity [vascular endothelial growth factor (VEGF) immunoreactivity and microvessel density (MVD) using cluster of differentiation 34 (CD34) immunoreactivity]. RESULTS Total testosterone, DHT, PSA level and prostate volume were evaluated and with the exception of DHT and PSA level there was no statistically significant differences between the groups. When comparing changes in Hb and Ht between Group A and Group B before and after B-TURP, there was a statistically significant difference only in patients with large prostates of ≥50 mL (ΔHb 3.86 vs 2.05 g/dL and ΔHt 4.98 vs 2.64%, in Groups A and B, respectively). There was no significant difference in MVD and VEGF index in prostates of <50 mL, conversely in large prostates the difference become statistically significant. CONCLUSIONS Dutasteride was able to reduce operative and perioperative bleeding only in patients with large prostates (≥50 mL) that underwent B-TURP. Our findings are confirmed by Hb and Ht values reported before and after the B-TURP and reductions in the molecular markers for VEGF and CD34 in the dutasteride-treated specimens.

Abstract
OBJECTIVES To assess whether the proportion of men with clinically significant prostate cancer (PCa) is higher among men randomized to multiparametric magnetic resonance imaging (mp-MRI)/biopsy vs. those randomized to transrectal ultrasound (TRUS)-guided biopsy. METHODS In total, 1,140 patients with symptoms highly suggestive of PCa were enrolled and divided in 2 groups of 570 patients to follow 2 different diagnostic algorithms. Group A underwent a TRUS-guided random biopsy. Group B underwent an mp-MRI and a TRUS-guided targeted+random biopsy. The accuracy of mp-MRI in the diagnosis of PCa was calculated using prostatectomy as the standard of reference. RESULTS In group A, PCa was detected in 215 patients. The remaining 355 patients underwent an mp-MRI: the findings were positive in 208 and unremarkable in 147 patients. After the second random+targeted biopsy, PCa was detected in 186 of the 208 patients. In group B, 440 patients had positive findings on mp-MRI, and PCa was detected in 417 at first biopsy; 130 group B patients had unremarkable findings on both mp-MRI and biopsy. In the 130 group B patients with unremarkable findings on mp-MRI and biopsy, a PCa Gleason score of 6 or precancerous lesions were detected after saturation biopsy. mp-MRI showed an accuracy of 97% for the diagnosis of PCa. CONCLUSIONS The proportion of men with clinically significant PCa is higher among those randomized to mp-MRI/biopsy vs. those randomized to TRUS-guided biopsy; moreover, mp-MRI is a very reliable tool to identify patients to schedule in active surveillance.

Abstract
Varicocele is the main cause of male infertility. Treatment stops continuous damage to spermatogenesis, thereby potentially improving fertility. Among all the available procedures, the ante-grade scrotal sclerotherapy (ASS), a combined radiological-surgical approach first introduced by Tauber, is gaining more popularity due to its minimal invasiveness. We report the case of a 35-year old man who was subjected to a colonic resection after antegrade scrotal sclerotherapy for varicocele. The procedure was necessary due to the embolization of venous anastomosis between the spermatic and mesenteric veins, which were not detectable at the preoperative phlebography.

Abstract
Purpose Regulation of the apoptotic process has an important role in spermatogenesis. p53 has a prominent function in apoptosis and recent data suggest a relationship between varicocele and p53 codon 72 polymorphism and male infertility. This prompted us to study the relationship between this polymorphism and spermatic parameters. Methods We studied 134 subjects with varicocele admitted consecutively to the outpatients Department of Infertility at the University of Rome La Sapienza. We investigated in these subjects the effect of a strong apoptosis inducer, the p53 codon 72 *Arg/*Arg genotype, on spermatic parameters.The p53 codon 72 genotype was determined by DNA analysis. Results The proportion of spermatozoa with abnormal (curvilinear) motility is higher in men with the *Arg/*Arg genotype than in men carrying the *Pro allele (p = 0.003). No statistical significant relationship has been observed with spermatozoa concentration and atypical spermatozoa. Conclusions We conclude: the p53 codon 72*Arg/*Arg genotype, with its strong apoptotic effects, negatively influences spermatozoa motility and male fertility.

Abstract
Background Bacterial prostatitis (BP) is a common condition accounting responsible for about 5-10% of all prostatitis cases; chronic bacterial prostatitis (CBP) classified as type II, are less common but is a condition that significantly hampers the quality of life, (QoL) because not only is it a physical condition but also a psychological distress. Commonly patients are treated with antibiotics alone, and in particular fluoroquinolones are suggested by the European Urology guidelines. This approach, although recommended, may not be enough. Thus, a multimodal approach to the prolonged antibiotic therapy may be helpful. Methods 210 patients affected by chronic bacterial prostatitis were enrolled in the study. All patients were positive to Meares-Stamey test and symptoms duration was > 3 months. The purpose of the study was to evaluate the efficacy of a long lasting therapy with a fluoroquinolone in association with a nutraceutical supplement (prulifloxacin 600 mg for 21 days and an association of Serenoa repens 320 mg, Lactobacillus Sporogens 200 mg, Arbutin 100 mg for 30 days). Patients were randomized in two groups (A and B) receiving respectively antibiotic alone and an association of antibiotic plus supplement. Results Biological recurrence at 2 months in Group A was observed in 21 patients (27.6%) and in Group B in 6 patients (7.8%). Uropathogens found at the first follow-up were for the majority Gram – (E. coli and Enterobacter spp.). A statistically significant difference was found at the time of the follow-up between Group A and B in the NIH-CPSI questionnaire score, symptoms evidence and serum PSA. Conclusions Broad band, short-lasting antibiotic therapy in association with a nutritional supplement (serenoa repens, lactobacillus sporogens and arbutin) show better control and recurrence rate on patients affected by chronic bacterial prostatitits in comparison with antibiotic treatment alone.

Abstract
OBJECTIVE Peyronie's disease (PD) is a fibrotic wound-healing condition of the tunica albuginea that results in penile deformity, curvature, hinging, narrowing and shortening, penile pain, and in some cases, erectile dysfunction (ED). Surgery remains the gold standard treatment option, ensuring the faster and trustworthy treatment. For those patients who have erectile dysfunction and PD, penile prosthesis placement with straightening procedure is the best method to solve both diseases. The aim of this article is to present the use of hydraulic penile prostheses AMS CX with Momentary Squeeze associated with a complete isolation of the neurovascular bundle in a complex case after removal of two previously implanted prostheses in a man suffering from Peyronie's disease and erectile dysfunction. MATERIAL AND METHOD A 50 year-old patient underwent two previous prosthetic implants in another hospital. The first implantation was performed using an infrapubic approach followed by placement of a three-component hydraulic penile prosthesis. After six months the prosthesis was removed using an infra-pubic approach and two soft prosthesis Virilis II were implanted during the same surgery. One year after the second operation we implanted a hydraulic penile prosthesis AMS CX with Momentary Squeeze after complete isolation of the neurovascular bundle, fixing the two crural tips at the same level of albuginea of the two corpora cavernosa. RESULT Twelve months after surgery the penis was completely straight without penile shortening and the patient was fully satisfied with his sexual life. CONCLUSION The procedure enabled a perfect alignment of the cylinders along the longitudinal axis and penile prosthetic symmetry to obtain a good penile rigidity and a perfect penile straightening.

Abstract
Fracture of the penis, a relatively uncommon emergency in Urology, consists in the traumatic rupture of the tunica albuginea of the corpus cavernosum. Examination and clinical history can be highly suspicious of penile fracture in the majority of cases and ultrasonography (USS) can be useful to identify the exact location of the tunical rupture, which is proximal in 2/3 of cases and therefore manageable through a penoscrotal approach. Although expensive and not readily available in the acute setting, Magnetic Resonance Imaging (MRI) may play a role in the differential diagnosis with rupture of a circumflex or dorsal vein of the penis or when the tunical rupture is not associated with tear of the overlying Buck's fascia. This form of imaging is more sensitive than USS at identifying the presence of a tunical tear. The treatment of choice is immediate surgical repair, which allows preserving erectile function and minimizing corporeal fibrosis.

Abstract
High-risk non-muscle invasive bladder cancer (NMIBC) progresses to metastatic disease in 10-15% of cases, suggesting that micrometastases may be present at first diagnosis. The prediction of risks of progression relies upon EORTC scoring systems, based on clinical and pathological parameters, which do not accurately identify which patients will progress. Aim of the study was to investigate whether the presence of CTC may improve prognostication in a large population of patients with Stage I bladder cancer who were all candidate to conservative surgery. A prospective single center trial was designed to correlate the presence of CTC to local recurrence and progression of disease in high-risk T1G3 bladder cancer. One hundred two patients were found eligible, all candidate to transurethral resection of the tumor followed by endovesical adjuvant immunotherapy with BCG. Median follow-up was 24.3 months (minimum-maximum: 4-36). The FDA-approved CellSearch System was used to enumerate CTC. Kaplan-Meier methods, log-rank test and multivariable Cox proportional hazard analysis was applied to establish the association of circulating tumor cells with time to first recurrence (TFR) and progression-free survival. CTC were detected in 20% of patients and predicted both decreased TFR (log-rank p < 0.001; multivariable adjusted hazard ratio [HR] 2.92 [95% confidence interval: 1.38-6.18], p = 0.005), and time to progression (log-rank p < 0.001; HR 7.17 [1.89-27.21], p = 0.004). The present findings provide evidence that CTC analyses can identify patients with Stage I bladder cancer who have already a systemic disease at diagnosis and might, therefore, potentially benefit from systemic treatment.

Abstract
BACKGROUND A Prostate Cancer Unit is a place where men can be cared for by specialists in prostate cancer (PC), working together within a multi-disciplinary team (MDT). The MDT approach guarantees a higher probability for the PC patient to receive adequate information on the disease and on all possible therapeutic strategies, balancing advantages and related side effects. Objecive: To analyze the role of a MDT in PC management and to compare some results in terms of characteristics and distribution of PC cases, obtained by a MDT, with those reported by a monodisciplinary urological unit. Outcome measurements and results: A high percentage of cases (47.6%) referred to our MDT were in the low risk group. In the Prostate cancer Unit the indications for primary therapies were more equally distributed between surgery (51.5%) and radiotherapy (45.4%). CONCLUSIONS The future of PC patients relies in a successful multidisciplinary collaboration between experienced physicians which can led to important advantages in all the phases of PC.

Abstract
OBJECTIVE To analyze feasibility and outcomes of laparoscopic partial nephrectomy (LPN) for endophytic hilar tumors in low-intermediate (ASA I-II) risk patients. METHODS This is a single centre retrospective study. From May 2009 to September 2011, 208 LPNs were performed at our institution. Overall 11 (5.2%) elective LPNs were for hilar tumors not visible on kidney surface. Hilar tumor was defined as a mass located in the renal hilum and in contact with a major renal vessel on preoperative imaging. Procedures were carried out by a single experienced surgeon (G.G.) via retroperitoneal approach by clamping the only main renal artery. RESULTS Mean (range) age of patients was 45.3 years (38.2-64.1), tumor size 1.6 cm (1.2-2.0), warm ischemia time 24 min (19-32), operative time 140 min (110-200) and estimated blood loss 270 ml (100-750). Two collecting system injuries were observed and repaired intraoperatively. No conversion to open surgery was required. Final pathological examination revealed 10 renal cell carcinomas and 1 oncocytoma. A negative surgical margin was obtained in 10/11 (91%) patients. Renal function and serum hemoglobin were nearly unaltered pre and post-surgery. No tumor recurrence was observed at mean (range) follow-up of 34 months (15-43). CONCLUSIONS In experienced hands, LPN represents a feasible, safe and effective treatment for selected patients diagnosed with endophytic hilar masses. A larger number of patients and longer follow-up are required to draw definitive conclusions.

Abstract
Congenital anomalies of the kidney and urinary tract are part of a family of diseases with different anatomical origins. Duplicated collecting systems can be defined as a renal unit containing 2 pyelocalyceal systems associated with a single ureter or with double ureters. The supernumerary kidney is a definitive accessory organ with its own collecting system, blood supply, and distinct encapsulated parenchima. The true incidence of supernumerary kidney remains unknown, but most cases are in males, are unilateral and on the left side. We present a case of an adult woman with a hypoplastic supernumerary kidney with a complete ureteral duplication and an ectopic junction. The case has been laparoscopically treated. We demonstrate that a laparoscopic nephro-ureterectomy is feasible and that the management of the complication (urinoma and fistula) can be managed conservatively.

Abstract
OBJECTIVE Penile prosthesis implantation is the solution of choice in patients who have failed or present contraindication to the use of all conservative treatment for erectile dysfunction (ED). Overall, satisfaction rates are high, with more than 80% of patients and partners fully satisfied with cosmetic and functional result of surgery. Chronic postoperative pain, penile shortening, soft or hyposensitive glans, pencil like penis syndrome and difficulty to cycle the device represent the most common causes of patient's dissatisfaction. Satisfaction rates are better assessed with the use of validated questionnaires such as the International Index of Erectile Function (IIEF) and the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) The aim of our study was to analyze the long-term mechanical reliability of the AMS 700CX/CXM inflatable penile prosthesis and the patient's satisfaction rate using IIEF and EDITS questionnaire as standard reference. MATERIALS AND METHODS A retrospective case notes review of all patients who have undergone implantation of a three pieces inflatable penile prosthesis AMS 700 CX and CXR between October 1997 and December 2010. Overall, 80 patients have undergone implantation of 3 pieces inflatable penile prosthesis AMS 700 CX InhibiZone. Patients have been administered the IIEF-5 and EDITS questionnaires in combination with a non validated 9 domain questionnaire that assesses penile rigidity, sensation, orgasmic function, frequency of intercourse, impact of surgery on the quality of life, satisfaction rate. RESULTS Overall 10 years survival estimate according to the Kaplan Meier method of AMS 700 CX touch pump and AMS 700 CX momentary squeeze pump are respectively 77.6% and 82.5%. The median postoperative IIEF5 and EDITS score were respectively 21.46 and 73.11, which show a high level of satisfaction. 59 patients (90.8%) were able to cycle the device and were engaging in penetrative sexual intercourse. CONCLUSIONS Penile prosthesis implantation yields excellent results in terms of cosmetic and functional outcome and therefore has a significant impact on patients' satisfaction, sex life and overall quality of life. Overall, long term reliability has been significantly improved and complication rates are low in the hands of experienced surgeons.

Abstract
INTRODUCTION Cystosarcoma phyllodes are very rare tumors and may be difficult to diagnose clinically. BACKGROUND Fibroadenomas have long been considered benign hyperplastic lesions rather than true neoplastic processes. However, previous clonality studies have shown differing results. AIM to assess diagnostic and treatment options for phyllodes tumor. MATERIALS AND METHODS A 41-year-old female patient undergoing assisted fertilization treatment. The patient underwent fine needle aspiration biopsy that confirmed fibroadenoma before the IVF attempt. At 17 weeks of gestation, due to an increase in volume of the fibroadenoma, an excisional biopsy was performer that showed a malignant phyllodes tumor. Then she underwent quadrantectomy and chemiotherapy After 1 year there was a recurrence of phyllodes tumors and she underwent mastectomy and chemotherapy. RESULTS Fibroadenoma that was transformed into high-grade malignant cystosarcoma after ovarian stimulation, relapsed after one year and it was not immediately diagnosed. The patient underwent mastectomy and chemotherapy. DISCUSSION it is difficult to diagnose recurrence and to determine tele frequency and the right treatment for such a rare cancer, so it is important to report any case in the literature. CONCLUSIONS We recommend to remove a fibroadenoma before attempting IVF for the risk of malignant transformation.
