RESUMEN
PURPOSE: To evaluate the durability, effectiveness, and safety of transperineal laser ablation (TPLA) of the prostate. MATERIALS AND METHODS: Patients with symptomatic benign prostatic hyperplasia (BPH) underwent TPLA with a 1,064-nm continuous-wave diode laser. International Prostate Symptom Score (IPSS), quality of life (QoL), postvoid residual (PVR), and prostate volume were evaluated at baseline and successive timepoints. RESULTS: Forty prospectively enrolled patients had follow-up of ≥36 months; median duration of follow-up was 57 months (range, 36-76 months). Compared with baseline, the median reduction in IPSS at 12-month follow-up was 74% (interquartile range [IQR], 60%-81%) (P < .001). Median QoL score at 12 months was improved from 5 (IQR, 4-5) at baseline to 1 (IQR, 0-1) (P < .001). Median PVR at 12 months decreased from 108 mL (IQR, 38-178 mL) to 13.5 mL (IQR, 0-40.5 mL) (P < .001), a median reduction of 88% (IQR, 61%-100%). At 12 months, median prostate volume was significantly reduced from 66 mL (IQR, 48.5-86.5 mL) to 46 mL (IQR, 36-65 mL) (P < .001), a median reduction of 32% (IQR, 21%-45%). For all of these parameters, the benefit of TPLA persisted at last follow-up, and all changes were statistically significant compared with baseline. There were no intraprocedural adverse events; periprocedural adverse events consisted of 1 case of prostatitis and 1 case of urinary tract infection (both Society of Interventional Radiology [SIR] Grade I). CONCLUSIONS: TPLA for symptomatic BPH produced durable benefits across a range of clinical outcomes and was well tolerated in follow-up at median duration of 57 months.

To the Editor, Erectile dysfunction (ED) is one of the most prevalent conditions affecting men globally, with significant psychological and social consequences. The prevalence varies across different populations, and it is estimated around 50% in men aged between 40 to 70. The etiology of ED is multifactorial, involving a complex crosstalk between psychological, hormonal, neurogenic, vascular, and structural factors [...].

Background and Objectives: Despite advancements in the diagnosis and treatment of testicular germ cell tumours (TGTCs), challenges persist in identifying reliable biomarkers for early detection and precise disease management. This narrative review addresses the role of microRNAs (miRNAs) as potential diagnostic tools and therapeutic targets in the treatment of TGCTs. Materials and Methods: Three databases (PubMed®, Web of Science™, and Scopus®) were queried for studies investigating the utility of miRNA as diagnostic tools, assessing their prognostic significance, and evaluating their potential to guide TGCT treatment. Different combinations of the following keywords were used, according to a free-text protocol: "miRNA", "non-coding RNA", "small RNA", "Testicular Cancer", "seminomatous testicular germ cell", "non-seminomatous testicular germ cell". Results: The potential of miRNAs as possible biomarkers for a non-invasive diagnosis of TGCT is appealing. Their integration into the diagnostic pathway for TGCT patients holds the potential to enhance the discriminative power of conventional serum tumour markers (STMs) and could expedite early diagnosis, given that miRNA overexpression was observed in 50% of GCNIS cases. Among miRNAs, miR-371a-3p stands out with the most promising evidence, suggesting its relevance in the primary diagnosis of TGCT, particularly when conventional STMs offer limited value. Indeed, it demonstrated high specificity (90-99%) and sensitivity (84-89%), with good positive predictive value (97.2%) and negative predictive value (82.7%). Furthermore, a direct relationship between miRNA concentration, disease burden, and treatment response exists, regardless of disease stages. The initial evidence of miRNA decrease in response to surgical treatment and systemic chemotherapy has been further supported by more recent results suggesting the potential utility of this tool not only in evaluating treatment response but also in monitoring residual disease and predicting disease relapse. Conclusions: MiRNAs could represent a reliable tool for accurate diagnosis and disease monitoring in the treatment of TGCT, providing more precise tools for early detection and treatment stratification. Nevertheless, well-designed clinical trials and comprehensive long-term data are needed to ensure their translation into effective clinical tools.

BACKGROUND/AIM: At present, multidisciplinary tumor boards (MDTB) are considered best practice in oncology. However, web-based virtualization of MDTB may increase participation in meetings, the number of cases discussed, and adherence to guidelines, deliver better treatment, and eventually improve outcomes for patients with prostate cancer. PATIENTS AND METHODS: This is an observational study focused on exploring the structuring process and implementing a multi-institutional virtual MDTB in Sicily, Italy. Other endpoints included the analysis of cooperation between participants, adherence to guidelines, patient outcomes, and patient satisfaction. RESULTS: Overall, 126 patients were referred to the virtual MDTB for a total of 302 cases discussed in an 18-month period. Nearly 45% of cases were referred from general hospitals or tertiary centers, 38% from comprehensive cancer centers, and only 17% from academic ones. Most health professional participants (95%) reported eliminating geographical barriers and consequently reducing costs and saving time as key advantages of virtual meetings over face-to-face ones. Using a specifically designed platform for virtual MDTBs was another excellent point, especially to geolocate clinical trials and time-lapse data storage. The majority of referred patients had stage T 3-4 prostate cancer (79%). Overall, 71% of proposals discussed were approved unchanged, while 19% changed after the virtual MDTB discussion. Debated points were mostly radiologic, surgical, medical, or radiation treatment-related issues. In particular, the prescriptive appropriateness of positron emission tomography with 68Ga-prostatic specific membrane antigen, newer drugs, radiation versus surgical approach, stage T3-4 cases, and adjuvant therapy represented the most debated issues. The proposed diagnostic and/or therapeutic options were controlled for adherence to the guidelines and/or updated scientific evidence. Overall, 98% of approved proposals and changes were in line with the guidelines. Overall, most participants felt virtual MDTB was very useful and case discussions led to a major change of strategy in 19% of cases. CONCLUSION: Virtual MDTBs are a very useful way to achieve best management of prostate cancer while saving time and fostering cooperation.

BACKGROUND: Prostate cancer is the second most commonly diagnosed cancer in men. The diagnostic accuracy in prostate cancer can be increased by employing a preliminary multiparametric MRI followed by a fusion-targeted biopsy. METHODS: To compare the diagnostic accuracy of fusion-targeted biopsy with the standard systematic biopsy in prostate cancer patients, we enrolled 139 patients on which we performed 139 prostate biopsies consisting of three targeted samples followed by 12 regular systematic samples. Based on histology, we analyzed the diagnostic performance of the two methods. RESULTS: Both methods were equally good at detecting clinically significant cancer (83.3%, 50/60), while systematic biopsy detected more clinically insignificant cancers. However, the best diagnostic performance is obtained by combining the two methods. CONCLUSION: The two methods are best seen as synergistic, and the addition of fusion biopsy can be used to detect more clinically significant prostate cancers than systematic biopsy alone.

BACKGROUND: Penile curvature (PC) can be surgically corrected by plication techniques or Nesbit corporoplasty. These shortening techniques can be complicated by post-operative: penile shortening, recurrent PC, palpable suture knots and erectile dysfunction. Furthermore, Nesbit procedures require the use of a penile tourniquet to avoid intraoperative bleeding. This observational study aims to assess the results of Nesbit modified corporoplasty, avoiding intraoperative use of tourniquet without risk of bleeding. The objective is to reduce penile ischemic anatomical and functional damages such as long-term erectile dysfunction. METHODS: Between January 2010 and March 2019, a total of 64 patients with congenital penile curvature (CPC) and Peyronie's disease (PD) underwent surgical correction with a Nesbit modified technique first time described by Rolle et al., with minimal technical differences. The operation notes were retrospectively reviewed. In particular, we evaluated pre- and post-operative erectile functions using IIEF-5 score, penile Doppler ultrasonography and overall patient satisfaction. RESULTS: During operations, no intraoperative bleeding was noted, and no short-term complications such as hematomas or neurovascular bundle lesions were reported. At 6 months, no palpable subcutaneous indurations and no sensory change were detected. Post-operative penile shortening was reported in 38 (59.4%) patients (mean 0.83±0.79 cm), but it did not influence the high overall satisfaction rate of 91.4%. Only 2 patients reported a slightly partial recurrence of curvature (<15%) with no need for a redo surgery. Mean IIEF-5 score increased from 17.1±5.2 to 20.8±3.9 at 6 months and 21.8±3.4 at 12 months (P<0.001 in both cases). Mean PSV also significantly increased at the end of follow-up (28.5±6.1 at baseline vs. 31.0±7.1 at 12 months, P=0.03). CONCLUSIONS: Considering the optimal results in terms of erectile functions increasing and absence of PC recurrence (>15°), we think that Nesbit modified corporoplasty without tourniquet application during reconstruction is a safe and effective surgical procedure for all kind of shortening corporoplasty to reduce the time of penile ischemia, preventing even serious consequences for the normal physiology of erection.
RESUMEN
PURPOSE: Greenlight laser is a mini-invasive technique used to treat Benign Prostatic Obstruction (BPO). Some of the advantages of GreenLight photoselective vaporization (PVP) are shorter catheterization time and hospital stay compared to TURP. Post-operative acute urinary retention (pAUR) leads to patients' discomfort, prolonged hospital stay and increased health care costs. We analyzed risk factors for urinary retention after GreenLight laser PVP. MATERIALS AND METHODS: In a multicenter experience, we retrospectively analyzed the onset of early and late post-operative acute urinary retention in patients undergoing standard or anatomical PVP. The pre-, intra- and post-operative characteristics were compared betweene patients who started to void and the patients who developed post-operative urinary retention. RESULTS: The study included 434 patients suitable for the study. Post-operative acute urinary retention occurred in 39 (9%). Patients with a lower prostate volume (P < .001), an adenoma volume lower than 40 mL (P < .001), and lower lasing time (P = .013) had a higher probability to develop pAUR at the univariate analysis. The multivariate logistic regression confirmed that lower lasing time (95% CI: 0.86-0.99, OR = 0.93, P = .046) and adenoma volume (95% CI: 0.89-0.98, OR = 0.94, P = .006) are correlated to pAUR. Furthermore IPSS ≥ 19 (95% CI: 1.19- 10.75, OR = 2.27, P = .023) and treatment with 5-ARI (95% CI: 1.05-15.03, OR = 3.98, P = .042) are risk factors for pAUR. CONCLUSION: In our series, post-operative acute urinary retention was related to low adenoma volume and lasing time, pre-operative IPSS ≥ 19 and 5-ARI intake. These data should be considered in deciding the best timing for urethral catheters removal.

BACKGROUND: We previously reported that loss of KRAS mutations ("regressive" mutational trajectories) from primary tumors to metastases associated with the oligo-metastatic status in colorectal cancer (CRC). The present study was undertaken in order to analyze the mutational trajectories of KRAS in a well-characterized cohort of CRC patients who developed poly- or oligo-metastatic disease. MATERIAL AND METHODS: Patients were treated and followed-up according to European Society of Medical Oncology guidelines. Primary CRC FFPE tissue and metastatic circulating-free DNA were extracted using the QIAamp DNA specific kits (Qiagen, Hilden, Germany). Samples were sequenced with the Oncomine Solid Tumour DNA kit (Thermo Fisher Scientific, Waltham, MA, USA). Plasma collection for liquid biopsy was done from 1 to 14 days before starting first-line chemotherapy. Analysis of the prognostic power of KRAS evolutionary trajectories was done with uni- and multivariate analyses. RESULTS: One-hundred-fourteen patients were enrolled. Sixty-three patients presented with mutated KRAS (mutKRAS) and 51 with wild-type KRAS (wtKRAS). KRAS mutational concordance was high (70.1%).Two divergent subsets were identified: mutKRAS in primary tumors and wtKRAS in metastatic ones (regressive: mutKRAS â wtKRAS in 8.8% of patients), and vice versa (progressive: wtKRAS â mutKRAS in 21.1% of patients). An association between KRAS regressive trajectory and the oligo-metastatic status (P <0.0001) was found. At multivariate analysis, regressive and progressive mutational trajectories emerged as independent prognostic factors for survival, with Hazard Ratios of 0.22 (CI 95%: 0.08-0.61; median survival: not reached) and 2.70 (CI 95%: 1.11-6.56, median survival: 12.1 months), respectively. CONCLUSIONS: Our data provide evidence that the evolutionary trajectories of KRAS can have a strong clinical prognostic role and that they can be involved in discriminating between poly-metastatic aggressive vs oligo-metastatic indolent CRC.
RESUMEN
Altitude exposure affects hormonal homeostasis, but the adaptation of different populations is still not finely defined. This study aims to compare the mid-term effects of combining physical activity and altitude hypoxia on hormonal profiles in foreign trekkers coming from Italy versus indigenous Nepalese porters during a Himalayan trek. Participants (6 Italians and 6 Nepalese) completed a 300 km distance in 19 days of an accumulated altitude difference of 16,000 m, with an average daily walk of 6 h. The effect of high altitude on hormonal pathways was assessed by collecting blood samples the day before the expedition and the day after its completion. Foreign trekkers had an additional follow-up sample collected after 10 days. The findings revealed a different adaptation of thyroidal and gonadal axes to mid-term strenuous physical activity combined with high-altitude hypobaric hypoxia. The thyroid function shifted to the protective mechanism of low free triiodothyronine (FT3), whereas the gonadal axis was suppressed. The Italian trekkers and Nepalese porters had lower total testosterone and 17-ß-estradiol levels after the expedition. At the follow-up, the Italians had increased testosterone values. Prolactin secretion decreased in the Italians but increased in the Nepalese. We conclude that exposure to high-altitude affects the hormonal axes. The effect seems notably pronounced for the hypothalamus-pituitary gonadal axis, suppressed after high-altitude exposure.

PURPOSE: Prostate biopsies may undergrade up to half of all prostate cancers (PCs), delaying definitive treatment by up to 3 years. One cause of undergrading is the partial sampling inherent in the technique. Because of this, a prostate biopsy that appears to be Gleason 3+3=6 may come either from a true 3+3=6 tumor or from a higher-grade tumor that has been sampled only partially. The main goal of the present study is to identify a way to distinguish these 2 kinds of "Gleason 3+3=6" biopsies.Mounting evidence hints at the possibility that Gleason pattern 3 associated with higher-grade PC (aG3) is biologically distinct from pure Gleason pattern 3 (pG3). MATERIALS AND METHODS: In this study, we used immunohistochemistry and computer-aided image analysis to compare the expression of Ki67, cyclin D1, MYC, and p53 between foci of aG3 and pG3, to search for a marker that could distinguish them. RESULTS: The expression of Ki67 differed significantly between pG3 and aG3. The average Ki67 labeling index was 1.63% for pG3 and 7.62% for aG3 (P<0.01); the average number of Ki67+ cells per high-power field was 17 for pG3 and 60 for aG3 (P<0.01). The other markers did not differ significantly between pG3 and aG3. CONCLUSIONS: When a biopsy only shows Gleason pattern 3 PC, Ki67 immunohistochemistry could be used to distinguish the nodules of true Gleason score 3+3=6 from those that only appear to be 3+3=6 because of a sampling error. This would dramatically improve the diagnostic performance of prostate biopsies and the management of early PC.

Hypoxia alters micturition, which influences bladder function by involving different neurological and humoral systems. In this study we assessed the mid-term effects of altitude hypoxia on uroflowmetry in healthy male lowlander native Nepali porters and Italian trekkers, four each, who coattended a Himalayan expedition. All the participants completed a 19-day trek along a demanding route with ascent and descent at the Kanchenjunga Mountain. They underwent micturition and urodynamic analysis twice, at low altitude of 665 m a.s.l. and high altitude of 4,750 m a.s.l. Statistical comparisons considered the altitude effects (low vs. high) and ethnicity (Italian vs. Nepali). Food consumption was recorded, and water and energy intake were calculated. We found trends of borderline significance in the mean urinary flow rate (Qmean) (p = 0.058; effect size η2 p = 0.478) and in Qmax to the advantage of the Nepali. There was no evidence of differences when comparing time to Qmax and urine volume at Qmax and Qmean for altitude or altitude × ethnicity. In addition, there was a lonely female participant, who, analyzed as a case report, showed increased Qmean at high altitude. Older age mitigated while energy intake potentiated the ethnic differences noted in uroflowmetry. We conclude that altitude hypoxia rather inappreciably affects micturition in healthy men. However, a trend for possible ethnic differences raises worthy of note perspectives on adaptive ability of micturition. Also, dietary intake and age should be considered as confounding elements when evaluating micturition.

Diuron [3-(3,4-dichlorophenyl)-1,1-dimethylurea] is a substituted urea herbicide, carcinogenic for the rat urinary bladder. It has been hypothesized that Diuron cytotoxicity, resulting in regenerative proliferation, leads to urothelial hyperplasia and, finally, to bladder tumors, but molecular mechanisms of carcinogenesis have not still fully investigated. Here, we report the results of a study aimed at verifying the involvement of BAG3, an intracellular protein expressed in several tumors, in the Diuron-induced carcinogenesis. For this purpose, we analyzed the effect of Diuron on human primary urothelial cells and on human dermal fibroblasts. We found that while high concentrations of Diuron have a cytotoxic effect in human primary urothelial cells, in the same cells, noncytotoxic concentrations of the herbicide induce BAG3 expression. These findings show that BAG3 is a molecular target of Diuron and unravel the possible involvement of BAG3 protein in bladder carcinogenesis induced by the herbicide. In addition, these results suggest that BAG3 might be a potential early biomarker of damage induced by chronic exposure to Diuron.

PURPOSE: To investigate the health-related quality of life of uro-oncologic patients whose surgery was postponed without being rescheduled during the coronavirus disease 2019 (COVID-19) pandemic. PATIENTS AND METHODS: From the March 1 to April 26, 2020, major urologic surgeries were drastically reduced at our tertiary-care referral hospital. In order to evaluate health-related quality-of-life outcomes, the SF-36 questionnaire was sent to all patients scheduled for major surgery at our department 3 weeks after the cancellation of the planned surgical procedures because of the COVID-19 emergency. RESULTS: All patients included in the analysis had been awaiting surgery for a median (interquartile range) time of 52.85 (35-72) days. The SF-36 questionnaire measured 8 domains: physical functioning (PF), role limitations due to physical health (PH), role limitations due to emotional problems (RE), energy/fatigue (EF), emotional well-being (EWB), social functioning (SF), bodily pain (BP), general health perceptions (GHP). When considering physical characteristics as measured by the SF-36 questionnaire, PF was 91.5 (50-100) and PH was 82.75 (50-100) with a BP of 79.56 (45-90). For emotional and social aspects, RE was 36.83 (0-100) with a SF of 37.98 (12.5-90). Most patients reported loss of energy (EF 35.28 [15-55]) and increased anxiety (EWB 47.18 [interquartile range, 20-75]). All patients perceived a reduction of their health conditions, with GHP of 49.47 (15-85). Generally, 86% of patients (n = 43) noted an almost intact physical function but a significant emotional alteration characterized by a prevalence of anxiety and loss of energy. CONCLUSION: The lockdown due to the novel coronavirus that has affected most operating rooms in Italy could be responsible for the increased anxiety and decrement in health status of oncologic patients. Without any effective solution, we should expect a new medical catastrophe-one caused by the increased risk of tumor progression and mortality in uro-oncologic patients.

Erectile dysfunction (ED) is defined as the inability to attain or maintain penile erection sufficient for successful sexual intercourse. ED carries a notable influence on quality of life, with significant implications for family and social relationships. Because atherosclerosis of penile arteries represents one of the most frequent causes of ED, patients presenting with it should always be investigated for potential coexistent coronary or peripheral disease. Up to 75% of patients with ED have a stenosis of the iliac-pudendal-penile arteries, supplying perfusion of the male genital organ. Recently the potential treatment of this pathological condition by percutaneous approaches has emerged with good angiographic results and with a significant improvement in symptoms and quality of life. This review will focus on the normal anatomy and physiology of erection, the pathophysiology of ED, the relation between ED and cardiovascular diseases and, lastly, on new treatment modalities aimed at restoration of normal erectile function.

OBJECTIVE: To describe the trend in surgical volume in urology in Italy during the coronavirus disease 2019 (COVID-19) outbreak, as a result of the abrupt reorganisation of the Italian national health system to augment care provision to symptomatic patients with COVID-19. METHODS: A total of 33 urological units with physicians affiliated to the AGILE consortium (Italian Group for Advanced Laparo-Endoscopic Surgery; www.agilegroup.it) were surveyed. Urologists were asked to report the amount of surgical elective procedures week-by-week, from the beginning of the emergency to the following month. RESULTS: The 33 hospitals involved in the study account overall for 22 945 beds and are distributed in 13/20 Italian regions. Before the outbreak, the involved urology units performed overall 1213 procedures/week, half of which were oncological. A month later, the number of surgeries had declined by 78%. Lombardy, the first region with positive COVID-19 cases, experienced a 94% reduction. The decrease in oncological and non-oncological surgical activity was 35.9% and 89%, respectively. The trend of the decline showed a delay of roughly 2 weeks for the other regions. CONCLUSION: Italy, a country with a high fatality rate from COVID-19, experienced a sudden decline in surgical activity. This decline was inversely related to the increase in COVID-19 care, with potential harm particularly in the oncological field. The Italian experience may be helpful for future surgical pre-planning in other countries not so drastically affected by the disease to date.

OBJECTIVES: To explore the safety and feasibility of photo-selective vaporization of the prostate (PVP) with GreenLight XPS 180 Watt laser (GL-180- W XPS) combined with other surgical procedures. MATERIAL AND METHODS: Data on patients in whom GL-180-W XPS was performed to relieve lower urinary tract symptoms/ benign prostatic hyperplasia (LUTS/BPH) symptoms were extracted from a multi-institutional database (2011-2016). Patients were stratified into two groups. In the first all patients who had GL-180-W XPS with a concomitant procedure during the same surgical session were included as cases while those who underwent GL-180-W XPS PVP only were included as control. RESULTS: A total of 487 patients were included. Fifty-eight (11.9%) patients underwent concomitant procedures. Multivariable linear regression models failed to find an association between concomitant procedures and longer laser time (p = 0.4). Similarly, multivariable linear regression models failed to find an association between concomitant procedures and laser time even when the analyses were repeated and stratified into endoscopic (p = 0.6) and open/laparoscopic (p = 0.4) procedures. Multivariable logistic regression models failed to demonstrate any association between concomitant procedures and early complications (OR:1.39, CI: 0.379-2.44, p = 0.2), late complications (OR:1.84, CI:0.78-3.98; p = 0.1) and acute urinary retention (OR:1.84, CI:0.78-3.98; p = 0.1). When the analyses were repeated and the concomitant procedures stratified into endoscopic and open/laparoscopic ones, they yielded virtually the same results. CONCLUSIONS: GL-180-W XPS PVP could be safely performed in concomitant endoscopic or open/laparoscopic surgery. These results should be taken into consideration in the counseling of the patient who might choose to undergo simultaneous procedures.

PURPOSE: To detect any choroidal thickness (CT) change in patients after alpha-lytic drugs withdrawal that could help in the cataract surgery timing decision. METHODS: Twenty-five eyes of 25 patients (mean age: 76 ± 7 years) under alpha-lytic therapy, and 25 eyes of 25 control subjects (CS) (mean age: 75 ± 7 years) without alpha-lytic therapy, both scheduled for cataract surgery in the fellow eye, were included in this observational, prospective, non-randomized study. All patients underwent EDI-OCT during the first preoperative visit and approximately 1 month (range 28-31 days) after alpha-lytic withdrawal. In the CS group, the OCT during preoperative visit and approximately 1 month after (range 28-31 days) the first examination was performed. Data normality with Kolmogorov-Smirnov test was checked and statistical evaluation with the Wilcoxon-signed rank test was performed. RESULTS: The mean subfoveal CT was 224 ± 79.7 µm during therapy and 217 ± 70.4 µm after withdrawal; 1.5 mm nasally from the fovea CT was 198 ± 83.8 µm and 194 ± 82.8 µm, respectively; and 1.5 mm temporally from the fovea CT was 217 ± 55.9 µm and 205 ± 54.4 µm, respectively. A statistically significant reduction (p < 0.05) in all the 3 measured CT points was found. In the CS no significant changes were detected (p > 0.05). CONCLUSION: No severe floppy iris syndrome was detected at the time of surgery. In these patients, CT decrease could be an important sign for cataract surgery timing decision.

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic has put a substantial burden on the Italian healthcare system, resulting in the restructuring of hospitals to care for COVID-19 patients. However, this has likely impacted access to care for patients experiencing other conditions. We aimed to quantify the impact of COVID-19 on access to care for patients with urgent/emergent urological conditions throughout Italy. MATERIALS AND METHODS: A questionnaire was sent to 33 urological units in the AGILE consortium, asking clinicians to report on the number of urgent/emergent urological patients seen and/or undergoing surgery over a 3-week period during the peak of the COVID-19 outbreak and a reference week prior to the outbreak. ANOVA and linear regression models were used to quantify these changes. RESULTS: Data from 27 urological centres in Italy showed a decrease from 956 patients/week seen just prior to the outbreak to 291 patients/week seen by the end of the study period. There was a difference in the number of patients with urgent/emergent urological disease seen within/during the different weeks (all p values < 0.05). A significant decrease in the number of patients presenting with haematuria, urinary retention, urinary tract infection, scrotal pain, renal colic, or trauma and urgent/emergent cases that required surgery was reported (all p values < 0.05). CONCLUSION: In Italy, during the COVID-19 outbreak there has been a decrease in patients seeking help for urgent/emergent urological conditions. Restructuring of hospitals and clinics is mandatory to cope with the COVID-19 pandemic; however, the healthcare system should continue to provide adequate levels of care also to patients with other conditions.

A rare disease in an unusual site can closely mimic a typical presentation of a common disease, sometimes with devastating consequences. We present a case of primary amelanotic malignant melanoma of the urethra in a male, with clinical and histological characteristics that could have led to a mistaken diagnosis of high-grade urothelial carcinoma. Amelanotic mucosal melanoma should be suspected in all cases of high-grade mucosal tumors with practically any appearance (epithelioid, sarcomatoid, anaplastic, mixed). Morphological hints pointing toward melanoma-such as the presence of sparse melanin pigment or melanoma in situ-should be sought, and if absent, an immunohistochemical panel comprising S100 and HMB45 should be performed.

BACKGROUND: Many pseudogenes possess biological activities and play important roles in the pathogenesis of various types of cancer including bladder cancer (BlCa), which still lacks suitable molecular biomarkers. Recently, pseudogenes were found to be significantly enriched in a pan-cancer classification based on the Cancer Genome Atlas gene expression data. Among them, the top-ranking pseudogene was the proliferation-associated 2G4 pseudogene 4 (PA2G4P4). METHODS: Genomic and transcript features of PA2G4P4 were determined by GeneBank database analysis followed by 5' RACE experiments. Therefore, we conducted a retrospective molecular study on a cohort of 45 patients of BlCa. PA2G4P4 expression was measured by RT-qPCR, whereas PA2G4P4 transcript distribution was analyzed by in situ hybridization on both normal and cancerous histological sections and compared to the immunolocalization of its parental PA2G4/EBP1 protein. Finally, we tested the effects of PA2G4P4 depletion on proliferation, migration, and death of BlCa cells. RESULTS: We showed for the first time PA2G4P4 overexpression in BlCa tissues and in cell lines. PA2G4P4 distribution strictly overlaps PA2G4/EBP1 protein localization. Moreover, we showed that PA2G4P4 knockdown affects both proliferation and migration of BlCa cells, highlighting its potential oncogenic role. CONCLUSIONS: PA2G4P4 may play a functional role as an oncogene in BlCa development, suggesting it as a good candidate for future investigation and new clinical applications.
