Abstract
BACKGROUND The proliferation antigen Ki-67 has been widely used in clinical settings for cancer staging for many years, but investigations on its biological functions have lagged. Recently, Ki-67 has been shown to regulate both the composition of the chromosome periphery and chromosome behaviour in mitosis as well as to play a role in heterochromatin organisation and gene transcription. However, how the different roles for Ki-67 across the cell cycle are regulated and coordinated remain poorly understood. The progress towards understanding Ki-67 function have been limited by the tools available to deplete the protein, coupled to its abundance and fluctuation during the cell cycle. RESULTS Here, we use a doxycycline-inducible E3 ligase together with an auxin-inducible degron tag to achieve a rapid, acute and homogeneous degradation of Ki-67 in HCT116 cells. This system, coupled with APEX2 proteomics and phospho-proteomics approaches, allows us to show that Ki-67 plays a role during DNA replication. In its absence, DNA replication is severely delayed, the replication machinery is unloaded, causing DNA damage that is not sensed by the canonical pathways and dependent on HUWE1 ligase. This leads to defects in replication and sister chromatids cohesion, but it also triggers an interferon response mediated by the cGAS/STING pathway in all the cell lines tested. CONCLUSIONS We unveil a new function of Ki-67 in DNA replication and genome maintenance that is independent of its previously known role in mitosis and gene regulation.

Abstract
PURPOSE Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is characterized by a multiform clinical presentation requiring a differentiated treatment based on different phenotypes including the psychosocial and sexual domains. The aim of this study was assessing the complex correlations between somatic, psychological, and sexual symptoms of CP/CPPS patients. MATERIALS AND METHODS We performed a cross-sectional study on patients attending a Prostatitis Clinic. Patients were administered the following questionnaires: National Institutes of Health- Chronic Prostatitis Symptom Index (NIH-CPSI), International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF), Premature Ejaculation Diagnostic Tool (PEDT), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder 7-item (GAD-7), Oxford Happiness Questionnaire (OHQ), and Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A). RESULTS Linear regression analyses show highly significant correlations between scores of the NIH-CPSI and the scores of the GAD-7, PHQ-9 and OHQ psychometric questionnaires. IPSS scores correlate significantly with the psychometric scores only when a non-parametric analysis is performed. IIEF and PEDT sexual function scores did not correlate with any of the psychometric tests. NIH-CPSI scores correlate positively with most of the TEMPS-A profiles but the hyperthymic profile correlated negatively with the total and QoL NIH-CPSI and with PEDT scores. CONCLUSIONS Scores measuring anxiety, depression, and psychological well-being in patients with CP/CPPS are strictly correlated with prostatitis-like symptoms although they are poorly correlated with symptoms of prostatism, as measured by IPSS, and not correlated with scores of sexual dysfunctions, as measured by IIEF and PEDT. A hyperthymic temperament may increase resilience against the disease.

Abstract
The identification of protein phosphatase 1 (PP1) holoenzyme substrates has proven to be a challenging task. PP1 can form different holoenzyme complexes with a variety of regulatory subunits, and many of those are cell cycle regulated. Although several methods have been used to identify PP1 substrates, their cell cycle specificity is still an unmet need. Here, we present a new strategy to investigate PP1 substrates throughout the cell cycle using clustered regularly interspersed short palindromic repeats (CRISPR)-Cas9 genome editing and generate cell lines with endogenously tagged PP1 regulatory subunit (regulatory interactor of protein phosphatase one, RIPPO). RIPPOs are tagged with the auxin-inducible degron (AID) or ascorbate peroxidase 2 (APEX2) modules, and PP1 substrate identification is conducted by SILAC proteomic-based approaches. Proteins in close proximity to RIPPOs are first identified through mass spectrometry (MS) analyses using the APEX2 system; then a list of differentially phosphorylated proteins upon RIPPOs rapid degradation (achieved via the AID system) is compiled via SILAC phospho-mass spectrometry. The "in silico" overlap between the two proteomes will be enriched for PP1 putative substrates. Several methods including fluorescence resonance energy transfer (FRET), proximity ligation assays (PLA), and in vitro assays can be used as substrate validations approaches.

Abstract
BACKGROUND Urinary incontinence and other urinary symptoms tend to be frequent at menopause because of hormonal modifications and aging. Urinary symptoms are associated with the genitourinary syndrome of menopause which is characterized by physical changes of the vulva, vagina and lower urinary tract. The treatment strategies for postmenopausal urinary incontinence are various and may include estrogens, anticholinergics, and pelvic floor muscle training. A comparison of these treatments is difficult due to the heterogeneity of adopted protocols. We systematically reviewed the evidence from randomized controlled trials (RCTs) focusing on treatment of postmenopausal women with urge incontinence. METHODS We conducted a systematic review and meta-analysis by searching PubMed and EMBASE databases for randomized controlled trials (RCTs) reporting results of treatments for postmenopausal urinary urge incontinence. Odds ratios for improvement of urinary incontinence were calculated using random effect Mantel-Haenszel statistics. RESULTS Out of 248 records retrieved, 35 eligible RCTs were assessed for risk of bias and included in the meta-analysis. Compared with placebo, systemic estrogens were associated with decreased odds of improving urinary incontinence in postmenopausal women (OR = 0.74, 95% CI: 0.61-0.91, 7 series, 17132 participants, Z = 2.89, P = 0.004, I2 = 72%). In most studies, no significant improvement in urinary symptoms was observed in patients treated with local estrogens, although they showed to be helpful in improving vaginal symptoms. Vitamin D, phytoestrogens and estrogen modulators were not effective in improving symptoms of incontinence and other symptoms of genitourinary menopause syndrome or yielded contradictory results. A randomized controlled trial demonstrated that oxybutynin was significantly better than placebo at improving postmenopausal urgency and urge incontinence. The combination of anticholinergics with local estrogens has not been shown to be more effective than anticholinergics alone in improving urinary incontinence symptoms in postmenopausal women. Physical therapy showed an overall positive outcome on postmenopausal urinary incontinence symptoms, although such evidence should be further validated in the frame of quality RCTs. CONCLUSIONS The evidence for effective treatment of postmenopausal urinary incontinence is still lacking. Welldesigned large studies having subjective and objective improvement primary endpoints in postmenopausal urinary incontinence are needed. At present, a combination of different treatments tailored to the characteristics of the individual patient can be suggested.

Abstract
Background This study aimed, first, to angiographically investigate and analyze prostatic artery (PA) origin in a Greek male population with benign prostatic hyperplasia (BPH) treated with prostatic artery embolization (PAE) and, second, to correlate prostatic arterial anatomy with technical and clinical aspects of PAE. Methodology This was a retrospective study of BPH patients who underwent PAE in a single tertiary center in Greece from June 2019 to July 2022. For the first part of the study, PA was imaged with computed tomography angiography (CTA) before PAE and with digital subtraction angiography (DSA) during PAE in all patients. A widely accepted system for the classification of PA origin was applied. Type I, a common origin of PA and superior vesical artery (SVA) from the anterior division of internal iliac artery (IIA). Type II, PA originating from the anterior division of IIA, separate from, and inferior to SVA. Type III, the origin of PA from the obturator artery. Type IV, the origin of PA from the internal pudendal artery. Type V, rarer origins of PA. For the second part of the study, a subgroup of patients from the first part (treated with the same PAE protocol and free of vascular pathology that could have interfered with the technical success of PAE) was selected. In this subgroup, differences in PA origin were correlated with technical aspects (feasibility of catheterization of PA, fluoroscopy time (FT), dose area product (DAP)) and clinical outcomes of PAE. Results After the exclusion of four patients, 159 patients were included in the first part of the study. From a total of 355 PAs, 110 (31%) were compatible with type I, 58 (16.3%) type II, 45 (12.7%) type III, 110 (31%) type IV, and 32 (9%) type V. PA origin from an accessory internal pudendal artery was the most common among the rare origins of type V. Regarding the second part of the study (a subgroup of 101 patients selected to facilitate comparisons between the different types of PA origin), type I was associated with significantly more incidences of failed or difficult catheterization of the PA compared to all other types combined (27/64 vs. 18/138, p < 0.001). Types III, IV, and V showed a relatively low degree of technical difficulty. Patients with type I PA origin of at least one pelvic side (subgroup (I), n = 48) had significantly longer FT and DAP compared to the rest (subgroup (O), n = 53). Clinical success rates of PAE were slightly lower for the subgroup (I), although the difference was not statistically significant (75.8% vs. 83.8% at 18 months post-PAE, p = 0.137). No major complications were observed. Conclusions This is the first study of PA origin in Greece. It was demonstrated that types I and IV of PA origin were the most common and had the same prevalence. Type I showed significantly higher technical difficulty compared to the others, but had no significant impact on the clinical outcomes of PAE.

Abstract
The technique of percutaneous thrombin injection (PTI) under contrast-enhanced ultrasound (CEUS) guidance for control of acute hemorrhage-active extravasation not associated with pseudoaneurysm is demonstrated in three cases: 1) Massive spontaneous retroperitoneal hematoma in a patient with multiple comorbidities. Contrast-enhanced computed tomography (CT) showed extensive active extravasation, which was only partially controlled by transarterial embolization. CEUS was performed in the angiography suite. Contrary to unenhanced US and colour Doppler US (CDUS), CEUS confirmed persistent extravasation; CEUS-guided PTI was performed immediately thereafter. 2) Large rectus sheath hematoma in a patient on anticoagulant therapy. Contrast-enhanced CT and unenhanced US/CD could not definitely diagnose extravasation. CEUS clearly showed extravasation and was used for guidance of PTI. 3) Chest wall hematoma complicating central venous catheter placement in a patient with coronavirus on anticoagulant therapy. CDUS was inconclusive. CEUS was performed at the bedside, clearly showed active extravasation, and was used for guidance of PTI. In all three cases, post-PTI CEUS confirmed the absence of residual enhancement of the hematomas, and the hemodynamic status of the patients improved. PTI appears to be effective in selected cases of hematomas associated with active extravasation. In this context, CEUS may be the most suitable modality for guidance and for an immediate evaluation of the treatment effect.

Abstract
Although SGLT2 inhibitors have been initially employed in the treatment of type 2 diabetes, their clinical use was later extended to the treatment of other conditions such as heart failure, chronic kidney disease and obesity. In patients with type 2 diabetes, the administration of SGLT2 inhibitors has been associated with an increased incidence of urogenital infections, which may be linked to high glucose levels in the urine. The rate of urogenital side effects may be different in non-diabetic patients. The aim of this study was to review the risk of urogenital infections in non-diabetic patients taking SGLT2 inhibitors. MATERIALS AND METHODS We conducted a systematic review and meta-analysis by searching PubMed and EMBASE for randomized controlled trials (RCTs) reporting urogenital adverse effects in non-diabetic patients treated with SGLT2 inhibitors. Odds ratios for urogenital infections were calculated using random effect Mantel-Haenszel statistics. RESULTS Out of 387 citations retrieved, 12 eligible RCTs were assessed for risk of bias and included in the meta-analysis. Compared to placebo, SGLT2 inhibitors were associated with increased odds of genital infections (OR 3.01, 95% CI: 1.93- 4.68, 9 series, 7326 participants, Z = 5.74, p < 0.0001, I2 = 0%) as well as urinary tract infections (OR 1.33, 95% CI: 1.13-1.57, 9 series, 7326 participants, Z = 4.05, p < 0.0001, I2 = 0%). When four trials investigating the effects of SGLT2 inhibitors in populations including both diabetic and non-diabetic patients were considered, administration of SGLT2 inhibitors in diabetic patients was associated with significantly higher odds of genital infections but not urinary tract infections compared to patients without type 2 diabetes. In patients taking placebo, the odds for urinary tract infections were significantly increased in diabetic patients compared to non-diabetic patients. CONCLUSIONS The risk of genital infections is increased also in non-diabetic patients taking SGLT2 inhibitors although at a lesser extent that in diabetics. A careful assessment of the local anatomical conditions and of the history of previous urogenital infections is desirable to select those patients who need more intense follow-up, possibly combined with prophylactic measures of infections during treatment with SGLT2 inhibitors.

Abstract
INTRODUCTION/AIM A spectrum of psychological problems is commonly found in CP/CPPS patients, though it is not yet clear whether, a priori, psychological dysfunctions are the cause of these pain syndromes, or whether these pain conditions are themselves causing psychological disturbances. In this article we present the current perspective on the impact of psychological problems in chronic prostatitis syndromes and we discuss the implications thereof from a clinical perspective. MATERIALS AND METHODS A database and a manual search were conducted in the MEDLINE database of the National Library of Medicine, EMBASE, and other libraries using the key words "prostatitis syndromes", "chronic bacterial prostatitis", "chronic pelvic pain", in various combinations with the terms "psychological issues", "depression" "anxiety", "stress", "unhappiness", "cognitive status" and "personality". Two independent reviewers performed data extraction. We included clinical studies with available information on chronic prostatitis and related psychological conditions. We considered full-text written papers. We excluded reviews and case reports. In order to reduce the risk of bias we analyzed only studies including patients with confirmed CBP or CP/CPPS. Bibliographic information in the selected publications was checked for relevant records not included in the initial search. RESULTS Database search allowed us to retrieve 638 studies to which we added to 16 additional studies retrieved by hand-searching. After screening, 34 relevant papers were identified for thorough review. Most studies included patients with chronic pelvic pain and prostatitis-like symptoms, whereas a smaller number of studies included patients with methodologically con- firmed CP/CPPS including studies with a microbiologically confirmed diagnosis of CBP. The psychosocial factors examined in the selected studies include pain, catastrophizing, stress, personality factors and social aspects. Comorbid psychiatric disorders evidenced in the studies included depression, anxiety and trauma-related disorders, somatization disorders, and substance abuse. Some studies investigated the association of pain with each individual psychological disturbance, while others examined the impact of pain in association with the overall quality of life. Sample size, study design and diagnostic measures varied among studies. CONCLUSIONS Despite limitations and variations in sample size, study design and diagnostic measures in all included studies, a relation between chronic prostatitis and psychological problems is a consistent finding. The existing evidence does not permit to definitely conclude whether psychological problems are a risk factor for CP/CPPS or whether they represent an array of symptoms that are associated with the exacerbation of this disease.

Abstract
The chromosome periphery is a network of proteins and RNAs that coats the outer surface of mitotic chromosomes. Despite the identification of new components, the functions of this complex compartment are poorly characterised. In this study, we identified a novel chromosome periphery-associated protein, CCDC86 (also known as cyclon). Using a combination of RNA interference, microscopy and biochemistry, we studied the functions of CCDC86 in mitosis. CCDC86 depletion resulted in partial disorganisation of the chromosome periphery with alterations in the localisation of Ki-67 (also known as MKI67) and nucleolin (NCL), and the formation of abnormal cytoplasmic aggregates. Furthermore, CCDC86-depleted cells displayed errors in chromosome alignment, altered spindle length and increased apoptosis. These results suggest that, within the chromosome periphery, different subcomplexes that include CCDC86, nucleolin and B23 (nucleophosmin or NPM1) are required for mitotic spindle regulation and correct kinetochore-microtubule attachments, thus contributing to chromosome segregation in mitosis. Moreover, we identified CCDC86 as a MYCN-regulated gene, the expression levels of which represent a powerful marker for prognostic outcomes in neuroblastoma.

Abstract
BACKGROUND Overactive bladder (OAB) symptoms of frequency, urgency and urge incontinence are frequently associated with known neurological diseases like multiple sclerosis (MS), spinal cord injury (SCI), Parkinson's disease (PD), stroke. OBJECTIVE The aim of our study was to review the efficacy of pharmacological and non-pharmacological treatments for neurogenic overactive bladder. MATERIALS AND METHODS We searched two electronic databases (PubMed and EMBASE) for randomized controlled trials focusing on pharmacological and non-pharmacological medical treatments for overactive bladder symptoms associated with neurological diseases published up to 30 April 2022. RESULTS A total of 157 articles were retrieved; 94 were selected by title and abstract screening; after removal of 17 duplicates, 77 records were evaluated by full-text examination. Sixty-two studies were finally selected. The articles selected for review focused on the following interventions: anticholinergics (n = 9), mirabegron (n = 5), comparison of different drugs (n = 3), cannabinoids (n = 2), intravesical instillations (n = 3), botulinum toxin (n = 16), transcutaneous tibial nerve stimulation (TTNS) (n = 6), acupuncture (n = 2), transcutaneous electrical nerve stimulation TENS (n = 4), pelvic floor muscle training (PFMT) (n = 10), others (n = 2). Anticholinergics were more effective than placebo in decreasing the number of daily voids in patients with PD (mean difference [MD]- 1.16, 95 % CI - 1.80 to - 0.52, 2 trials, 86 patients, p < 0.004), but no significant difference from baseline was found for incontinence episodes and nocturia. Mirabegron was more effective than placebo in increasing the cystometric capacity in patients with MS (mean difference [MD] 89.89 mL, 95 % CI 29.76 to 150.01, 2 trials, 98 patients, p < 0.003) but no significant difference was observed for symptom scores and bladder diary parameters. TTNS was more effective than its sham-control in decreasing the number of nocturia episodes (MD -1.40, 95 % CI -2.39 to -0.42, 2 trials, 53 patients, p < 0.005) but no significant changes of OAB symptom scores were reported. PFMT was more effective than conservative advice in decreasing the ICIQ symptom score (MD, -1.12, 95 % CI -2.13 to -0.11, 2 trials, 91 patients, p = 0.03), although the number of incontinence episodes was not significantly different between groups. CONCLUSIONS The results of the meta-analysis demonstrate a moderate efficacy of all considered treatments without proving the superiority of one therapy over the others. Combination treatment using different pharmacological and non-pharmacological therapies could achieve the best clinical efficacy due to the favorable combination of the different mechanisms of action. This could be associated with fewer side effects due to drug dosage reduction. These data are only provisional and should be considered with caution, due to the few studies included in metaanalysis and to the small number of patients.

Abstract
OBJECTIVE Proton pump inhibitors are widely used as treatment of acid-related disorders. They are considered safe although their long-term use has been associated with some adverse effects including an increased propensity for urinary calculi formation. The aim of this study was to systematically review available data from studies evaluating the association of PPIs and nephrolithiasis. MATERIALS AND METHODS We searched two electronic databases (PubMed and EMBASE) for cohort studies or case-control studies evaluating the relationship between treatment with proton pump inhibitors and the risk of stone formation published up to 31 October 2022. The overall association of PPIs and urinary calculi was analyzed using a random effects model (RevMan5). The quality of the included studies was assessed using the Newcastle-Ottawa Quality Assessment Scale. RESULTS A total of 550 studies were retrieved; 7 were selected by title and abstract screening; after removal of duplicates, 4 records were evaluated by full-text examination. An additional study was retrieved by handsearching the references included in screened studies. In the unadjusted analysis, the odds of urinary calculi were greater in subjects taking PPIs compared to controls (unadjusted OR = 2.10, 95% CI 1.74-2.52, p < 0.00001). The pooled odds ratio of two case-control studies confirmed that use of PPIs increased the odds of urinary calculi compared with non-use (OR 2.44, 95% CI 2.29 to 2.61). Pooled analysis of three cohort studies evaluating incident nephrolithiasis showed an overall hazard ratio estimate of 1.34 (95% CI = 1.28-1.40). One study found lower urinary citrate and urinary magnesium levels in subjects exposed to PPIs. The Newcastle-Ottawa Quality Assessment Scale scores ranged between 6 and 8. CONCLUSIONS PPIs showed an association with urinary calculi in patients included in the studies included in this review. If these data will be confirmed in adequately powered randomized trials, clinicians may consider limiting the long-term use of PPIs, to avoid unnecessary prolongation of treatment. Urinary magnesium and citrate should be evaluated in renal stone forming patients taking PPIs to supplement their intake when requested.

Abstract
OBJECTIVE To review the evidence concerning treatment-related gynecomastia in patients taking spironolactone, antiandrogens, 5 alpha-reductase inhibitors, lipid-lowering and psychotropic drugs. MATERIAL AND METHODS A search of Medline and EMBASE was performed up to 30 June 2021. We included randomized controlled trials comparing the effects of a drug belonging to these classes versus placebo or versus a drug of the same class. RESULTS A total of 32 randomized controlled trials were included in the final review. There was an increased odds of gynecomastia in men receiving antiandrogens (OR = 17.38, 95% CI: 11.26 to 26.82; 6 trials, 9599 participants) and 5 alpha-reductase inhibitors compared to controls (OR = 1.77, 95% CI: 1.53 to 2.06; 7 series out of 6 trials, 34860 participants). The use of spironolactone in mixed gender populations was characterized by significantly higher odds of having gynecomastia compared to controls (OR = 8.39, 95% CI: 5.03 to 13.99; 14 trials, 3745 participants). No placebo-controlled trials focusing on the risk of gynecomastia in patients taking antipsychotic drugs was available, although there was a significant difference in the odds of having gynecomastia in a comparison between risperidone and quetiapine (OR = 4.32, 95% CI: 1.31 to 14.27; 3 trials, 343 participants). Limited evidence about the effects of statins on mammary glands was found. CONCLUSIONS Antiandrogens and to a lesser extent 5 alphareductase inhibitors and spironolactone are associated with an increased risk of developing gynecomastia. Such effect can be explained by a modification of the testosterone to estradiol ratio. Gynecomastia (and galactorrhea) associated to the use of conventional and certain atypical antipsychotics can be related to high prolactin levels.

Abstract
The Acute Cystitis Symptom Score (ACSS) is a patient self-reporting questionnaire for the clinical diagnosis and patient-reported outcome (PRO) in women with acute uncomplicated cystitis (AC). The aim of the current study (part II) is the clinical validation of the Greek ACSS questionnaire. After linguistic validation according to internationally accepted guidelines and cognitive assessment (part I), the clinical validation was performed by using the Greek ACSS study version in 92 evaluable female participants including 53 patients with symptoms suspicious of AC and 39 controls. The clinical outcome using the ACSS questionnaire at different points in time after the start of treatment was demonstrated as well. The age (mean ± SD) of the 53 patients (44.7 ± 17.0 years) and 39 controls (49.3 ± 15.9 years) and their additional conditions at baseline visits, such as menstruation, premenstrual syndrome, pregnancy, menopause, diabetes mellitus, were comparable. There was, however, a significant difference (p < 0.001) between patients and controls at baseline visit regarding sum score of the ACSS domains, such as typical symptoms and quality of life. The clinical outcome of up to 7 days showed a fast reduction of the symptom scores and improvement of quality of life. The optimal thresholds for the patient-reported outcome of successful therapy could be established. The linguistically and clinically validated Greek ACSS questionnaire can now be used for clinical or epidemiological studies and also for patients' self-diagnosis of AC and as a PRO measure tool.

Abstract
Introduction: Chronic bacterial prostatitis (CBP) is a difficult-to-eradicate infection. Antibacterial therapy with currently licensed agents is hindered due to the increasing emergence of pathogen resistance worldwide and to frequent infection relapse. With limited treatment options, physicians are investigating new agents, which, however, may raise safety concerns.Areas covered: Antibacterial agents currently licensed for CBP were not considered. Available reports about the safety and efficacy of antibacterial agents that have been clinically tested or tentatively used to treat CBP in single cases were evaluated. This review also focused on agents targeting Gram-positive pathogens, whose prevalence as causative agents of CBP is increasing.Expert opinion: (i) Most antibacterial agents considered in this review have been administered off-label in the interest of patients, and their use requires particular caution. (ii) Reports describing the usage of many of the drugs reviewed here are still scant, and readers should be warned of the limited published evidence supporting therapy for CBP with these agents. (iii) As treatment must extend over several weeks, medium-term adverse events may occur and therapy should be individualized, taking into account the dosage and the potential toxicity of each specific antibiotic. Regarding dangerous drug-drug interactions, particular attention should be paid to the risk of ECG-QT-interval elongation.

Abstract
BACKGROUND Sexual dysfunction may be a side effect of treatment with antipsychotics, antidepressants, and other psychotropic drugs. AIM To review the evidence concerning male sexual dysfunctions in patients taking psychotropic drugs to provide specific information to nonpsychiatric physicians for the management of these dysfunctions. METHODS A systematic search of Medline and Embase databases was performed up to October 15th, 2020. We included randomized controlled trials comparing the effects of psychotropic drugs versus placebo or versus another drug of the same class, for at least 5 weeks. OUTCOMES We considered studies whose male population could be evaluated separately from the female population and with a separate analysis of the different phases of the male sex cycle. RESULTS We included 41 studies in the final review. There was a significant association between sexual dysfunction and antidepressant drug therapy, compared to placebo (decreased libido OR 1.89, 95% CI:1.40 to 2.56, 22 series, 11 trials, 7706 participants; erectile dysfunction OR = 2.28, 95% CI: 1.31 to 3.97; 11 trials, 3008 participants; ejaculatory dysfunction OR = 7.31, 95% CI: 4.38 to 12.20,19 trials, 3973 participants). When the effects of selective serotonin reuptake inhibitors (SSRIs) were evaluated separately from those of serotonin/norepinephrine reuptake inhibitors (SNRIs), the use of SNRIs but not that of SSRIs was characterized by significantly higher odds of erectile dysfunction compared to placebo. Only limited data were found regarding the effects of antipsychotics on the phases of the male sexual cycle, as it was shown that aripiprazole and risperidone showed lower and higher odds for erectile or ejaculatory dysfunction, respectively, compared to other atypical antipsychotics. CLINICAL IMPLICATIONS Treatment of male sexual dysfunction in patients taking psychotropics requires a basic knowledge of the different drugs that affect sexual function with different mechanisms. STRENGTHS & LIMITATIONS The effects of psychotropic drugs on erectile function and ejaculation were evaluated separately. The great variability of the mechanisms of action makes it difficult to make comparisons between the effects of the different classes of psychotropic drugs. CONCLUSIONS Administration of antipsychotics affects male sexual function with different mechanisms, although the increase in prolactin values associated with the administration of first-generation antipsychotics and some atypical, such as risperidone, seems to play a primary role in determining male sexual dysfunction. Most antidepressants cause decreased libido, ejaculatory and erectile dysfunction, however the administration of SNRIs appears to be possibly associated with a specific risk of erectile dysfunction.

Abstract
Chronic prostatic inflammation may be classified into three types that share similar symptoms and are distinguished on the basis of microbiological findings. In the present study, consecutive cases of chronic prostatic inflammation and infection were retrospectively reviewed in order to explore the clinical course and long-term outcomes. The cohort consisted of patients with symptoms of prostatitis who visited the Urology Clinic of the Tzaneion Hospital (Piraeus, Greece) between March 2009 and March 2019. The patients were subjected to the Meares and Stamey ‘4-glass’ test and patients with febrile prostatitis were evaluated with a single mid-stream ‘clean’ urine sample culture. Bacterial identification was performed using the Vitek 2 Compact system and the sensitivity test with the disc and the Vitek 2 system. A total of 656 patients with prostatitis-like symptoms with 1,783 visits for investigation and follow-up were reviewed and patients were divided into two major groups. Group 1 consisted of 549 cases with a single set of chronic prostatitis (CP)-like symptoms assessed in up to three visits. National Institutes of Health (NIH) category II CP (NIH-II) was most frequently diagnosed in those patients (37,6%). At the follow-up, 125 patients were identified as having a type of CP different from that determined initially. Group 2 (107 cases) had recurring episodes of prostatitis-like symptoms assessed or confirmed over the course of 4-18 visits. Most patients (54.2%) were initially diagnosed with NIH-II followed by disease-free periods and recurrence/reinfection or by shifts to NHI-IIIB. In conclusion, CP remains a poorly understood n medical condition characterized by a variety of clinical manifestations and by transitions between different CP classes during its course.

Abstract
OBJECTIVE To evaluate the effects of psychotropic drugs on bladder function. MATERIALS AND METHODS A systematic review was carried out by searching PubMed and Embase databases for randomized controlled trials enrolling patients treated with psychotropic drugs with available information on treatment-related urinary disorders. RESULTS A total of 52 studies was selected. In antidepressant therapy, bladder voiding symptoms, rather than storage symptoms, were more frequently observed. Pooled analysis demonstrated a higher odds ratio (OR) of voiding disorders in comparison with placebo (OR: 3.30; confidence interval [CI]: 1.90-5.72; 7856 participants; p < 0.001). Odds for voiding dysfunction was higher for tricyclic antidepressants and for Serotonin and Norepinephrine Reuptake Inhibitors (SNRIs) when compared to Selective Serotonin Reuptake Inhibitors (SSRIs). Treatment with antipsychotics was associated with heterogeneous urinary disorders including emptying and storage disorders. OR for incontinence in patients with dementia taking antipsychotics was higher than placebo (OR: 4.09; CI: 1.71-9.79, p = 0.002) with no difference between different atypical antipsychotics. Rate of voiding disorders was not different between conventional and atypical antipsychotics (OR: 1.64; CI: 0.79-3.39, p = 0.19), although quetiapine showed higher odds to cause voiding dysfunction than other atypical antipsychotics (OR: 2.14; CI: 1.41-3.26; p > 0.001). CONCLUSIONS In patients taking tricyclic antidepressants or SNRIs, bladder voiding disorders, could be the side effects of therapy rather than symptoms of a urological disease. Patients treated with these drugs should be actively monitored for the appearance of urinary symptoms. Antipsychotic treatment is associated with various urinary side effects requiring a tailored approach.

Abstract
Sugammadex is routinely used as an effective neuromuscular blockade reversal agent. Several studies have indicated that it may prolong the prothrombin time (PT) and the activated partial thromboplastin time (aPTT). This review gathers the relevant in vivo studies to accumulate knowledge on the subject. Nine studies were included. According to the results, sugammadex seems to lead to a transient increase in aPTT and PT values, compared to standard care. However, the clinical impact seems to be trivial. Nevertheless, the trials' findings reveal great heterogeneity, preventing a meta-analysis. Therefore, more well-designed studies are needed to lead to prudent conclusions.

Abstract
We report a case of chronic left flank neuropathic pain after a renal cyst removal in a 54-year old female. The patient was treated with a single application of capsaicin 8% dermal patch, with satisfactory results at an eight week follow up visit. Capsaicin 8% dermal patch could be a suitable alternative in the conservative management of post laparoscopy neuropathic pain, as it can be effective and has a well-tolerated safety profile.

Abstract
Background To present and evaluate an approach for reduction of utilization of steep oblique angiographic projections during prostatic artery embolization (PAE). Methods Single-center, retrospective study of patients who underwent bilateral PAE (from October 2018 to November 2019) and in whom it was possible to embolize PA of at least one pelvic side utilizing anteroposterior projections only (AP-PAE group), with the following techniques: Identification of the origin of PA on anteroposterior angiographic views. Utilization of anatomic landmarks from the planning computed tomographic angiography. Distal advancement of the angiographic catheter or microcatheter in the anterior division of internal iliac artery. Gentle probing with microguidewire at the expected site of origin of the PA. The AP-PAE approach was initially applied to all PAE patients during the study period and when this approach failed, additional steep oblique projections were acquired; patients who underwent bilateral PAE, with both anteroposterior and oblique projections for both pelvic sides, formed the standard PAE (S-PAE) group. The AP-PAE group was compared with S-PAE group in terms of baseline clinical and anatomic features, technical/procedural aspects and outcomes. Results Forty-six patients (92 pelvic sides) were studied. AP-PAE was feasible in 12/46 patients (26.0%): unilateral AP-PAE in 9/46 patients (19.5%); bilateral AP-PAE in 3/46 patients (6.5%). AP-PAE group had larger prostates (p = 0.047) and larger PAs (p < 0.001). Body mass index (BMI) and other baseline features were comparable between the two groups (mean BMI, AP-PAE group: 27.9 ± 3.6, S-PAE group: 27.0 ± 3.5, p = 0.451). Mean fluoroscopy time and dose area product were lower in AP-PAE group (46.3 vs 57.9 min, p = 0.084 and 22,924.9 vs 35,800.4 μGy.m2, p = 0.018, respectively). Three months post PAE, comparable clinical success rates (11/12 vs 31/34, p = 0.959) and mean International Prostate Symptom Score reduction (60.2% vs 58.1%, p = 0.740) were observed for AP-PAE and for S-PAE group, respectively. No major complications were encountered. Conclusion AP-PAE is associated with significant reduction in radiation exposure and appears to be feasible, safe and effective, but it can be applied in a relatively small percentage of patients.

Abstract
Chronic prostatitis (CP) is a common health condition in men. Albeight obvious, a relationship between microbial induced prostatic inflammation and sexual function has not been as thoroughly investigated. Aiming to investigate possible associations between sexuality/sexual orientation and chronic bacterial prostatitis, we retrospectively evaluated 1783 visits (2009-2019) owing to investigation of prostatitis-like symptoms and routine follow up. A total of 389 patients, provided information regarding sexual orientation and sexuality. The mean age was 45,5 years. According their report, 92.28% were heterosexual, 6.16% homosexual and 1.54% bisexual. Regarding sexuality, 26,6% reported multiple sexual partnerships while 73,4% reported single sexual partnerships. There was a statistically significant association between chronic bacterial prostatitis as initial diagnosis and having multiple sexual partnerships. In contrast, the association between CBP and sexual orientation was not statistically significant Similarly, no significant association between any therapy outcome and having multiple sexual partners was established. Our findings suggest a connection between sexual practices and the onset of CBP which should be further investigated in order to reach to scientific conclusions.

Abstract
OBJECTIVES We performed a questionnaire survey to investigate various issues in the diagnosis of chronic prostatitis (CP) performed by Greek urologists and to assess some aspects of prostatitis workup in Greece. Replies were compared with those of Italian clinical research partners in an attempt to clarify the CP diagnostic approaches in Southern European Mediterranean countries. METHODS We translated the original Italian questionnaire presented by Magri and Montanari in the frame of a urological congress held in Milan on October 26th, 2018. Τhis 5-item questionnaire explores clinical practice characteristics, attitudes, and diagnostic strategies for the management of chronic prostatitis (Chronic Bacterial Prostatitis or Chronic Prostatitis/Chronic Pelvic Pain Syndrome, according to NIH criteria). After its validation the questionnaire was uploaded in the internet and Greek healthcare professionals were invited by mail to respond. Responses were compared with those of Italian urologists, in order to determine similarities and differences in attitudes between clinicians regarding the diagnostic assessment of CP. RESULTS There is a wide variation in participants' preferences for diagnostic methods, laboratory tests and clinical examinations both in Italy and in Greece. In both countries many diagnostic tests performed in affected patients are only geared to exclude other treatable conditions (e.g., benign prostatic hyperplasia, bladder cancer), but more suitable methods and tests for the assessment of CP are less frequently used. CONCLUSIONS Urologists' choices for the diagnostic workup of CP, show a wide international or intra-national variability between Greece and Italy. Although several diagnostic tests are available to differentiate and categorize the types of CP, a large number of urologists use less suitable methods and tests. This fact reflects both the lack of consensual vision in the literature and the difficulties encountered on a daily basis by the physicians. Under the light of this evidence, the need of studies establishing consensual guidelines for the optimal diagnosis of CP is becoming imperative.

Abstract
INTRODUCTION The role of Ureaplasma spp. (UPs) in the pathogenesis of chronic prostatitis is debated. The lithogenic potential of UPs could be a risk factor for the development of chronic prostatitis. METHODS A total of 143 patients with identification of UPs were retrospectively selected from a database including patients with prostatitis-like symptoms who were studied according to the same protocol including clinical, microbiological and microscopic evaluation, and transrectal prostate ultrasound. A control group of patients with negative UPs was considered including 393 with chronic bacterial prostatitis (CBP), 42 patients with Chlamydia trachomatis (CT), and 781 patients with chronic pelvic pain syndrome. UPs and Mycoplasma hominis (MH) were identified using a semiquantitative assay. RESULTS Calcifications were observed more frequently in patients with UPs (64%) than in patients with CBP without UPs (39%), CT infection (37%), and chronic pelvic pain syndrome (29%) (p < 0.0001). UPs were isolated in VB1 alone in 35 patients (urethral UPs), in expressed prostatic secretion (EPS) or post-massage urine (VB3) or sperm in 77 patients (prostatic UPs) and associated with other pathogens in 31 patients (associated UPs). Calcifications were more frequent in prostatic UPs (71%) and associated UPs (73%) than in urethral UPs (34%). Mean NIH-CPSI scores were not significantly different between groups, although mean WBC counts of sperm of patients with urethral UPs were significantly lower than in patients with prostatic UPs (p = 0.000) and associated UPs (p = 0.002). CONCLUSIONS UPs identification in the urogenital fluids is related to higher rates of prostate calcifications. The ability of UPs to promote the formation of calcifications could be related to the chronicization of prostate infection. In particular, the presence of UPs in VB3/EPS/sperm is associated with higher rates of calcifications and high WBC sperm counts, suggesting a partial or full causative role of UPs in the pathogenesis of this disease.

Abstract
Prostatic artery embolization (PAE) has gained acceptance as a minimally invasive, safe and effective treatment of symptomatic benign prostatic hyperplasia. Radiologic imaging is an indispensable part of post-interventional evaluation of PAE and serves both clinical and investigational purposes. In this context, ultrasonography (US) has a central and multifaceted role. Gray-scale US is routinely utilized for measurement of significant outcome parameters (prostatic volume, intra-vesical prostatic protrusion and post-void residual volume) before and after PAE. Improvement of these parameters may become more obvious one-month post-PAE, or later. Contrast-enhanced US (CEUS) with intravenous administration of a second-generation echo-enhancer can demonstrate prostatic infarcts (as enhancement defects) immediately post-PAE and monitor their resolution over time. The volume of prostatic infarcts can also be measured and compared to prostatic volume. Prostatic infarction is a definite sign of the local efficacy of PAE and a predictor of prostate shrinkage and (at least in some patients) of clinical success. CEUS can also be performed intraoperatively in the angio-suite, for on-site evaluation of the ischemic effect; a variation of this technique, with intraarterial (instead of intravenous) administration of diluted echo enhancer, can also be applied intraoperatively, to map the embolized territory and to prevent non-target embolization. Initial experience with US-elastographic techniques (shear-wave and strain elastography) has shown that they can detect and quantify the improvement of tissue elasticity post-PAE, thus providing new insights into the therapeutic mechanisms of this treatment. With utilization of high-end equipment, experience and standardized imaging protocols, US could be the primary modality for imaging evaluation of PAE.

Abstract
A focused, single outcome meta-analysis on the protective role of extracts of green tea catechins against prostate cancer. Randomized, placebo-controlled studies enrolling patients with a histologically confirmed diagnosis of high-grade Prostate Intraepithelial Neoplasia or Atypical Small Acinar proliferation but no prostate cancer were included. Meta-analysis for binary data was performed using Mantel-Haenszel statistics, using a random-effects model. Heterogeneity was investigated by calculating the I2. Four studies matched the inclusion criteria for the review. The pooled population was 223 patients; 114 and 109 patients were randomized to catechin and placebo groups, respectively. Nine cases of prstate cancer occurred in the catechin arm (7.9%), and 24 cases were reported in the placebo arm (22%). Pooled analysis resulted in a significant reduction of cancer risk in favor of the catechin arm (risk-ratio = 0.41; 95% CI: 0.19- 0.86; I2 = 0). In conclusion, our data suggest that the intake of concentrated green tea catechin preparations may confer a significant protective effect to carriers of early neoplastic lesions in the prostate. The quality of the evidence is moderate, and additional, largescale studies are warranted to substantiate these preliminary findings.

Abstract
INTRODUCTION/AIM Despite accumulated knowledge, several microbiological aspects of chronic bacterial prostatitis (CBP) remain uncertain. The aim of our study was to determine microbiological characteristics on our CBP population. MATERIALS The material of this retrospective study consisted in bacterial isolates from urine and/or prostatic secretions or sperm cultures (total ejaculate) obtained from individuals with prostatitis symptoms and from patients with febrile relapses of CBP visiting our department, from 03/2009 to 03/2015. Retrospective data from an Italian single-center database (years 2009-2015) were also collected for a tentative comparison of pathogen prevalence between chronic bacterial prostatitis cases assessed in Greece and Italy. RESULTS A total of 389 bacterial isolates obtained from eligible Greek patients constituted the material of the study. While E coli was the most frequent individual pathogen, Gram-positive species were overly more frequent than Gram-negative. Besides the high frequency of E. coli and E. faecalis isolates the most remarkable similarity between Greek and Italian databases was the wide array of different Gram-positive and Gram-negative species isolated from CBP patients. CONCLUSIONS In Greece, the incidence of CBP is possibly higher than that reported in international surveys. Similarities between Greek and Italian databases suggest geographical trends in CBP epidemiology.

Abstract
INTRODUCTION/AIM Although prostatic calculi/calcifications are encountered frequently in the urological practice, little is known about the incidence of such lesions, their mechanism of formation, their relationship to other prostate conditions and their clinical significance. The purpose of this study is to describe the characteristics and to investigate the clinical significance of prostatic calcifications (PCs) in patients with chronic bacterial prostatitis (CBP). MATERIALS AND METHODS This study was conducted between 01/02/2013 and 20/02/2018. The patient population for this study included subjects with or without PCs and a confirmed diagnosis of NIH category II Chronic Bacterial Prostatitis (CBP). Demographics and clinical history of each assessed patient were reviewed. Eligible patients underwent prostatic ultrasound with post-void residual measurement, and the Meares-Stamey "4-glass" test. Symptom severity was measured using the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and the International Prostatic Symptoms Score (IPSS). Antimicrobials were administered to confirmed cases of CBP according to the results of susceptibility tests. After four weeks off-therapy, the NIH-CPSI and IPSS tests were repeated. Variables were compared between patients with and without prostatic calcifications. RESULTS Ninety-five CBP patients were included in the study. According to the presence of PCs detected by ultrasound examination, patients were divided into two groups: 41 had PCs (group 1) and 54 didn't (group 2). No significant between-group baseline differences were found regarding age, marital status, prostate volume, the proportion of common CBP pathogens. Concerning highrisk sexual behavior, a significantly higher number of men with PCs practiced anal penetration. Moreover, a significantly higher number of men with PCs had a history of chronic prostatitis relapsing episodes. Microbiological eradication and the complete resolution of clinical symptoms occurred in similar proportions between the two groups. However, intergroup analysis resulted in significantly higher scores of the NIH-CPSI test in group 1, both at the pre-therapy and at the post-therapy time points. Conversely, no IPSS score differences between groups 1 and 2 were found at both pre- and post-therapy time points. CONCLUSIONS Prostatic calcifications do not seem to influence the microbiological outcome of antibacterial treatment. However, the CBP symptoms appear to be more severe in carriers of prostatic calcifications, either before or after antibacterial therapy.

Abstract
PURPOSE We aimed to assess the clinical and predictive role of contrast-enhanced ultrasonography (CEUS) as the primary method for imaging evaluation of prostatic artery embolization (PAE) for the treatment of symptomatic benign prostatic hyperplasia (BPH). METHODS Thirty-one patients with symptomatic BPH, treated with PAE from October 2016 until February 2018, were enrolled in this prospective, single-center study. Microspheres (100-700 µm) were utilized for PAE. International prostate symptom score (IPSS), quality of life (QoL), maximum urinary flow (Qmax), prostatic volume (PV) and post void residual volume (PVR) were measured at baseline and at 1, 3, and 6 months post PAE. Unenhanced transabdominal US was utilized for PV and PVR measurements; prostatic enhancement was studied with transabdominal CEUS at baseline, during the procedure, 1 day and 1, 3, and 6 months post PAE. Technical success was defined as embolization of the PA of at least one pelvic side. Clinical success was based on the improvement of IPSS and QoL, with no need for any additional treatment. Follow-up time ranged from 6 to 18 months (mean, 9.7±4.3 months). Clinical success rates were calculated and changes in prostatic enhancement were correlated with the outcome parameters. RESULTS Technical success rate was 90.3%. Clinical success rates at 3, 6, and 12 months post PAE were 85.7%, 85.7%, and 79.1% respectively. Improvement of outcome parameters (baseline vs. 6-month values) was statistically significant, with 12.4 points mean reduction of IPSS (50.4%, P = 0.003), 2.0 points mean reduction of QoL (45.4%, P < 0.001), 30.3 mL mean reduction of PV (30.2%, P < 0.001), 72.6 mL mean reduction of PVR (51.8%, P = 0.005) and 8.6 mL/s mean increase in Qmax (103%, P = 0.002). The most significant complications were bladder ischemia (n=1), and ischemic rectal ulcer (n=1), both attributable to nontarget embolization, with complete recovery. CEUS 1 day post PAE demonstrated prostatic infarcts in 26/28 (92.8%) patients. The percentage of prostatic infarction (pPI, defined as prostatic infarcted volume 1 day post PAE divided by baseline PV) was 1%-71%. There was a very strong positive correlation between pPI and prostate shrinkage (r=0.81, P < 0.001), but a weak correlation between pPI and the improvement of the other outcome parameters (r= 0.01-0.36; P = 0.093-0.965). However, in the subgroup of patients with indwelling bladder catheter (9/28 patients), successful removal of the catheter was achieved only in patients with pPI>10%. CONCLUSION CEUS appears to be a practical method for the study of the local ischemic effect of PAE, with potential predictive value.

Abstract
BACKGROUND Mounting worldwide resistance trends make the use of fluoroquinolone (FQ) antibacterial agents increasingly difficult. This is felt more acutely in the case of urogenital infections, which are mainly caused by Gram-negative pathogens. For years, levofloxacin and other FQs have been the first-line drugs for treating National Institutes of Health (NIH) category II chronic bacteria prostatitis (CBP). Eradication rates achieved by levofloxacin in the frame of randomized trials vary greatly, ranging between 71 and 86%. OBJECTIVES This was a retrospective observational study to investigate the efficacy of levofloxacin against CBP in a real-life setting (urological outpatient wards). METHODS A database including the clinical records of >2,500 CBP patients was reviewed. Patients were selected based on strict inclusion criteria. They were treated for 4 weeks with 500 mg levofloxacin per day, alone or combined with other antibacterials. Besides standard urological procedures including the 4-glass test for pathogen isolation, international symptom questionnaires (the NIH Chronic Prostatitis Symptom Index [NIH-CPSI] and International Prostate Symptom Score [IPSS]) were administered. RESULTS Pathogen eradication was achieved in 79% of the cases treated with levofloxacin as a single agent and 87.8% of patients who received a combination of levofloxacin and azithromycin. The 11% increase in the eradication rate in the latter group is statistically significant. In addition, the levofloxacin-azithromycin combination caused a significant decrease in prostate volume and significantly increased the bladder-voided volume. IPSS and NIH-CPSI values and the urinary peak flow rate decreased to a similar extent in both treatment groups. No adverse effects were reported by patients belonging to either treatment group. CONCLUSION Levofloxacin retained its therapeutic efficacy in patients assessed in a real-life setting, and high eradication rates were attained when it was administered as a single agent. A combination of an FQ with azithromycin induced a significant improvement of eradication rates. This strategy may be an interesting option in both first-referral and relapsing cases, although caution should be exercised when patients are at risk of developing arrhythmias, tendinitis, or other adverse effects.

Abstract
The modern clinical research on prostatitis started with the work of Stamey and coworkers who developed the basic principles we are still using. They established the segmented culture technique for localizing the infections in the males to the urethra, the bladder, or the prostate and to differentiate the main categories of prostatitis. Such categories with slight modifications are still used according to the NIH classification: acute bacterial prostatitis, chronic bacterial prostatitis, Chronic Pelvic Pain Syndrome (CPPS) and asymptomatic prostatitis. Prostatic inflammation is considered an important factor in influencing both prostatic growth and progression of symptoms of benign prostatic hyperplasia and prostatitis. Chronic inflammation/neuroinflammation is a result of a deregulated acute phase response of the innate immune system affecting surrounding neural tissue at molecular, structural and functional levels. Clinical observations suggest that chronic inflammation correlates with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and benign prostatic hyperplasia (BPH) and an history of clinical chronic prostatitis significantly increases the odds for prostate cancer. The NIHNIDDK classification based on the use of the microbiological 4- glasses localization test or simplified 2-glasses test, is currently accepted worldwide. The UPOINT system identifies groups of clinicians with homogeneous clinical presentation and is used to recognize phenotypes to be submitted to specific treatments. The UPOINTS algorithm implemented the original UPOINT adding to the urinary domains (U), psycho-social (P), organspecific (O), infection (I), neurological (N), muscle tension and tenderness (T) a further domain related to sexuality (S). In fact sexual dysfunction (erectile, ejaculatory, libido loss) has been described in 46-92% of cases with a high impact on the quality of life of patients with CP/CPPS. Prostatic ultrasound represents the most popular imaging test in the work-up of either acute and chronic prostatitis although no specific hypo-hyperechoic pattern has been clearly associated with chronic bacterial prostatitis and CPPS. Use of a digital-processing software to calculate the extension of prostatic calcification area at ultrasound demonstrated a higher percentage of prostatic calcification in patients with chronic bacterial prostatitis. Multiparametric Magnetic Resonance Imaging (mpMRI) is the current state-of-the art imaging modality in the assessment of patients with prostate cancer although a variety of benign conditions, including inflammation, may mimic prostate cancer and act as confounding factors in the discrimination between neoplastic and non-neoplastic lesions. Bacteria can infect prostate gland by: ascending the urethra, reflux of urine into the prostatic ducts, direct inoculation of bacteria through inserted biopsy needles or hematogenous seeding. Enterobacteriaceae are the predominant pathogens in acute and chronic bacterial prostatitis, but an increasing role of Enterococci has been reported. Many strains of these uropathogens exhibit the ability to form biofilm and multidrug- resistance. Sexually Transmitted Infections (STI) agents, in particular Chlamydia trachomatis and Mycoplasma genitalium, have been also considered as causative pathogens of chronic bacterial prostatitis. On the contrary the effective role in genital diseases of other "genital mycoplasmas" is still a much debated issue. Sexually Transmitted Infections agents should be investigated by molecular methods in both patient and sexual partner. "Next generation" investigations, such as cytokine analysis, cytological typing of immune cells could help stratifying the immune response. Epigenetic dysregulation of inflammatory factors should be investigated according to systemic and compartment-specific signals. The search for biomarkers should also include evaluation of hormonal pathways, as measurement of estrogen levels in semen. Antimicrobials are the first line agents for the treatment of bacterial prostatitis. The success of antimicrobial treatment depends on the antibacterial activity and the pharmacokinetic characteristics of the drug which must reach high concentrations in prostate secretion and prostate tissue. Acute bacterial prostatitis can be a serious infection with a potential risk for urosepsis For iInitial treatment of severely ill patients, intravenous administration of high doses of bactericidal antimicrobials, such as broad-spectrum penicillins, third-generation cephalosporins or fluoroquinolones, is recommended in combination with an aminoglycoside. Use of piperacillin-tazobactam and meropenem is justified in presence of multiresistant gramnegative pathogens. The antibiotic treatment of chronic prostatitis is currently based on the use of fluoroquinolones that, given for 2 to 4 weeks, cured about 70% of men with chronic bacterial prostatitis. For the treatment of Chlamydial prostatitis macrolides were shown to be more effective than fluoroquinolones, whereas no differences were observed in microbiological and clinical efficacy between macrolides and tetracyclines for the treatment of infections caused by intracellular pathogens. Aminoglycosides and fosfomycin could be considered as a therapeutic alternative for the treatment of quinolone resistant prostatitis. Use of alpha-blockers in CP/CPPS patients with urinary symptoms and analgesics +/- non steroidal anti-inflammatory drugs (NSAID), in presence of pain demonstrated a reduction of symptoms reduction and an improvement of quality of life, although long term use of NSAID is limited by side effect profile. However, the multimodal therapeutic regimen by contemporary use of alphablockers, antibiotics and anti-inflammatory showed a better control of prostatitis symptoms than single drug treatment. Novel therapeutic substances for the treatment of pain, such as the cannabinoid anandamide would be highly interesting to test. An alternative for the treatment of chronic prostatitis/chronic pelvic pain syndrome is phytotherapy, as primary therapy or in association with other drugs. Quercetin, pollen extract, extract of Serenoa repens and other mixtures of herbal extracts showed a positive effect on symptoms and quality of life without side effects. The association of CP/CPPS with alterations of intestinal function has been described. Diet has its effects on inflammation by regulation of the composition of intestinal flora and direct action on the intestinal cells (sterile inflammation). Intestinal bacteria (microbiota) interacts with food influencing the metabolic, immune and inflammatory response of the organism. The intestinal microbiota has protective function against pathogenic bacteria, metabolic function by synthesis of vitamins, decomposition of bile acids and production of trophic factors (butyrate), and modulation of the intestinal immune system. The alteration of the microbiota is called "dysbiosis" causing invasive intestinal diseases pathologies (leaky gut syndrome and food intolerances, irritable bowel syndrome or chronic inflammatory bowel diseases) and correlating with numerous systemic diseases including acute and chronic prostatitis. Administration of live probiotics bacteria can be used to regulate the balance if intestinal flora. Sessions of hydrocolontherapy can represent an integration to this therapeutic approach. Finally, microbiological examination of sexual partners can offer supplementary information for treatment.

Abstract
Urinary tract infections are among the most common infectious diseases in humans. Today, resistance to nearly all antimicrobial classes is dramatically growing, and extremely drug-resistant or even pan-drug resistant pathogens are increasingly isolated around the world. It is foreseen that in the next decades the world will be facing a major medical emergency generated by the rapid spread of pathogens carrying resistance determinants of unprecedented power. Carbapenemase-producing Enterobacteriaceae, multidrug- resistant Enterococci and fluoroquinolone resistance determinants in both Gram-negative and Gram-positive uropathogens are among the greatest emergencies. In this article, the major emerging threats of particular interest to urologists are reviewed, worldwide resistance trends are illustrated, and novel and older - but still active - recommended drugs are summarized.

Abstract
AIMS To assess the feasibility, findings and potential value of early post-interventional, contrast-enhanced ultrasonographic (CEUS) study of prostate artery embolization (PAE). MATERIAL AND METHODS Fourteen patients treated with PAE for symptomatic benign prostatic hyperplasia were prospectively included in the study. Sonographic evaluation of the prostate included: 1) baseline transabdominal and transrectal CEUS (ta-CEUS and tr-CEUS, respectively) 1-3 days prior to PAE; 2) early post PAE CEUS, with ta-CEUS immediately post PAE and tr-CEUS 3 days post PAE; and 3) follow-up with ta-CEUS and tr-CEUS 3 months post PAE. A brief unenhanced US study preceded each CEUS. Post-therapeutic changes in size, echogenicity and enhancement of the prostate were recorded and were correlated with clinical outcomes. RESULTS PAE resulted in clinical success in 11/14 patients (78.5%). All sonographic studies were technically adequate, with the exception of ta-CEUS immediately post PAE in 2/14 (14.2%) patients. CEUS studies immediately post PAE and 3 days post PAE showed non-enhancing, welldefined infarctions of the prostate in 10/14 patients (71.4%). There was a strong correlation between ta-CEUS immediately post PAE and tr-CEUS 3 days post PAE regarding the measurements of prostatic infarctions (r =0.98, p< 0.01). The presence of infarctions on early post PAE CEUS was associated with clinical success (p=0.01) and their extent correlated with the degree of prostate shrinkage on 3-month follow-up (r=0.84, p<0.05). The 3 cases of failed PAE showed no infarctions and no prostate shrinkage. CONCLUSIONS Early post-interventional CEUS of PAE is feasible and may have clinical and prognostic value.

Abstract
AIM Prostate artery embolization (PAE) is a non invasive modality for the treatment of benign prostate hypertrophy (BPH) related lower urinary tract symptoms (LUTS). As a relatively new procedure, data determining the clinical success is somehow scarce. In the present article we examine the current clinical outcome measures in order to identify the most accurate. RESULTS Current imaging outcome measures are consistent with clinical ones only in the group of patients with adenomatous- dominant BPH while are inconsistent in patients with small sized adenomas. CONCLUSIONS Additional studies and/or evaluation tools are needed in order to provide accurate evaluation of clinical success in the subgroup of patients with non- adenomatous-dominant BPH while they may inspire new options and novel techniques for both BPH treatment and treatment-follow up.

Abstract
Purpose Despite recent progress in the management of chronic bacterial prostatitis (CBP), many cases relapse. Increased drug resistance patterns of responsible bacteria have been proposed as the most probable causative factor. Driven by the limited number of previous studies addressing this topic, we aimed to study whether antibiotic resistance increases in patients with CBP when relapse occurs. A secondary aim of this study was to determine the resistance patterns of responsible bacteria from patients with CBP. Materials and Methods The study material consisted of bacterial isolates from urine and/or prostatic secretions obtained from patients with CBP. Bacterial identification was performed by using the Vitek 2 Compact system and susceptibility testing was performed by disc diffusion and/or the Vitek 2 system. Interpretation of susceptibility results was based on Clinical and Laboratory Standards Institute guidelines. Results A total of 253 samples from patients diagnosed with CBP for the first time (group A) and 137 samples from relapsing patients with a history of CBP and previous antibiotic treatment (group B) were analyzed. A significant reduction in bacterial resistance to the less used antibiotics (TMP-SMX, tetracyclines, aminoglycosides, penicillins, and macrolides) was noted. An increase in resistance to quinolones of many bacteria that cause CBP was also noted with the increase in resistance of enterococcus strains being alarming. Conclusions Comparison of the resistance profile of CBP-responsible bacteria between samples from first-time-diagnosed patients and samples from relapsing patients revealed notable differences that could be attributed to previous antibiotic treatment.

Abstract
Self-insertion of foreign bodies in the urethra is most commonly associated with sexual or erotic arousal of adolescents with mental health disorders. Rarely it may practiced by healthy adults for masturbation. Migration of foreign bodies used for the abovementioned purpose from the urethra to adjacent organs is a relatively uncommon urologic problem that may cause serious complications which arose tardive. Presentation includes a variety of acute or chronic symptoms that depend of the underlying complications. The method of extraction depends on the shape, size and nature of the object and should be tailored according to the condition of the patient. In the present article we present a case of a rubber tube inserted to the urethra for erotic arousal purposes which migrated to the bladder during masturbation.

However, carcinomas with this peculiar morphologic feature have been also described in various anatomic locations and they are generally designated «lymphoepithelioma-like carcinomas». Those of the urinary bladder are uncommon as they account of 0.4%-1.3% of all bladder carcinomas. They may coexist with the conventional urothelial carcinoma. Given their rarity, there is poor information regarding their behaviour. Here we present a new case of lymphoepithelioma-like carcinoma in the bladder and we discuss its characteristics and prognosis.

Abstract
Ugo Foscolo, was an Italian writer, revolutionary and poet whose works rank among the masterpieces of Italian literature. Talented and well educated in philosophy, classics and Italian literature, Foscolo gave literary expression to his ideological aspirations and to his numerous amorous experiences in odes, sonnets, plays, poems and an epistolary novel. Concurrent with his rich literary output, Foscolo's correspondence represents a unique perspective from which to monitor his literary and political views and investigate aspects of his everyday life. Among other interesting information, one can find elements of Foscolo medical history which is generally unknown. In the present article we investigate the longstanding lower urinary tract symptoms as reported by the poet in his correspondence to his family and friends.

Abstract
PURPOSE The main aim of this study is to investigate the occurrence and severity of FSD in women working in tertiary hospitals. MATERIAL AND METHODS The study sample was drawn from health care women between the ages of 20 and 65 years, working in two hospitals in Greece. This descriptive study used a structured Greek questionnaire and sexual function screener and quality of life sectors were consisted of rated scale questions. Eighty eight questionnaires were returned properly completed. The statistical analysis used the SPSS statistical program. RESULTS Female sexual dysfunction is a highly prevalent health issue whose exact incidence is not well defined. Factors that can contribute to female sexual dysfunction may be psychogenic, physical, mixed or unknown. Each of these factors consists of individual components that influence the sexual response; however their precise impact in FSD development and progression is unknown. Moreover, the role of circadian rhythm disorders (especially that of shift work sleep disorder) to the development and progression of FSD has been poorly investigated. CONCLUSION Working environment and patterns of work schedules may play a role in FSD however it has been difficult to specify in what extent they contribute to FSD development.

Abstract
Urethral stricture is a common condition that can lead to serious complications such as urinary infections and renal insufficiency secondary to urinary retention. Treatment options include catheterization and dilation, urethroplasty and endoscopic internal urethrotomy as well. Although treatment option depends on the type, length and aetiology of stricture, the choice can be influenced to varying degrees by the simplicity of the method, the preferences of the patient the available accoutrements and the patient health condition. Both urethroplasty and endoscopic internal urethrotomy require anaesthesia and thus are not suitable for many elder and unfit for surgical treatment patients. On the other hand, dilations are easy to perform in every day clinical practice however they have been associated with iatrogenic urethral trauma. In contrast, balloon dilation under vision dilates by radial application of forces against the stricture, avoiding the potentially shearing forces associated with sequential rigid dilation. Since it reduces the possibility of an iatrogenic urethral trauma and the subsequent spongiofibrosis may lead into improved therapeutic outcomes. In this report we describe a technique for the treatment of urethral strictures with balloon dilation in elder and unfit for surgical treatment patients.

Abstract
PURPOSE We aimed to evaluate the combination of the modified Response Evaluation Criteria In Solid Tumors (mRECIST) and contrast-enhanced ultrasonography (CEUS) as a tool for the assessment of hepatocellular carcinoma treated with transarterial chemoembolization. MATERIALS AND METHODS Forty-seven hepatocellular carcinoma patients (80 target tumors suitable for mRECIST measurements) were studied. They were treated with scheduled transarterial chemoembolization with doxorubicin-eluting microspheres every 5-7 weeks. Imaging follow-up (performed one month after each transarterial chemoembolization) included a standard, contrast-enhanced modality (computed tomography [CT] in 12 patients or magnetic resonance imaging [MRI] in 35 patients) and CEUS. The study focused on response evaluation after the third transarterial chemoembolization. CEUS required a bolus injection of an echo-enhancer and imaging with a dedicated, low mechanical index technique. The longest diameters of the enhancing target tumors were measured on the CEUS or CT/MRI, and mRECIST criteria were applied. Radiologic responses were correlated with overall survival and time to progression. RESULTS The measurements of longest diameters of the enhancing target tumors were easily performed in all patients. According to mRECIST-CEUS and mRECIST-CT/MRI, complete response was recorded in five and six patients, partial response in 22 and 21 patients, stable disease in 16 and 14 patients, and progressive disease in four and six patients, respectively. There was a high degree of concordance between CEUS and CT/MRI (kappa coefficient=0.84, P < 0.001). Responders (complete+partial response) according to mRECIST-CEUS had a significantly longer mean overall survival and time to progression compared to nonresponders (37.1 vs. 11.0 months, P < 0.001 and 24.6 vs. 10.9 months, P = 0.007, respectively). CONCLUSION The mRECIST-CEUS combination is feasible and has prognostic value in the assessment of hepatocellular carcinoma following transarterial chemoembolization.

Abstract
Μalakoplakia is a rare inflammatory condition of the urogenital tract. The most frequently affected organ is urinary bladder. This condition has features of a granulomatous inflammation, the pathogenesis of which is not well understood. In this study, we presented a case of urinary bladder malakoplakia associated with advanced obstructive uropathy and renal failure.

Abstract
Evidence suggests that rural health care providers may be at increased risk for tobacco addiction. Few researchers have studied the habitual use of tobacco in rural Greece and no published studies have examined sustained tobacco use by nurses working in these areas or their knowledge and attitudes toward smoking cessation. To explore the above, the authors conducted a questionnaire-based study in 40 health centers in rural mainland and island Greece. Two hundred twenty nurses were surveyed (65% response rate). Thirty-two percent of the nurse respondents were smokers, 54% were non-smokers, and 14% were former smokers. Only 8% of respondents had been trained to assist clients with smoking cessation.

Abstract
Pseudosarcomatous myofibroblastic proliferations are very unusual entities of unknown etiology. Despite its benign nature, this entity can easily be misdiagnosed (both clinically and histologically) as a malignant neoplasm. Hereby, we report a case of a 15-year-old woman who presented to our hospital with a broad-based polypoid mass located in the left posterior wall of the urinary bladder. The patient underwent a transurethral resection of the lesion. Morphologic and immunohistochemical findings suggested the diagnosis of pseudosarcomatous myofibroblastic proliferation. The patient is free of recurrence 5 years after surgery.
