Non-cholera Vibrio spp. invasive infections in the summer following May 2023 flood disaster in Romagna, Italy: a case series. Eur J Clin Microbiol Infect Dis 2024:10.1007/s10096-024-04842-7. [PMID: 38735888 DOI: 10.1007/s10096-024-04842-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2024] [Accepted: 05/02/2024] [Indexed: 05/14/2024]
Abstract
Non-cholera Vibrio spp. includes ubiquitous organisms living in aquatic environments. Their occurrence is associated with global warming and meteorological disasters. In May 2023 the Romagna region, Italy, was affected by severe floods. In the following 15 weeks we observed 5 patients with invasive infections caused by V. vulnificus (3/5) and V. harveyi (2/5). All patients (median age 77 years) had medical comorbidities and shared exposure to seawater. Two patients needed surgery; 2 died. In conclusion, we observed an increased burden of Vibrio spp. invasive infections after May 2023 floods, affecting old patients with predisposing medical conditions.

Germline mutations in prostate cancer: a systematic review of the evidence for personalized medicine. Prostate Cancer Prostatic Dis 2023; 26:655-664. [PMID: 36434163 DOI: 10.1038/s41391-022-00609-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 10/26/2022] [Accepted: 10/31/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND The goal of precision medicine in prostate cancer (PCa) is to individualize the treatment according to the patient's germline mutation status. PCa has a very high rate of genetic predisposition compared with other cancers in men, with an estimated rate of cancers ascribable to hereditary factors of 5-15%. METHODS A systematic search (PubMed, Web of Science, and ClinicalTrials.gov) of English literature from 2000 to 2022, using the keywords "prostate cancer", "germline mutations", "family history", and "inheritance" was conducted, according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. RESULTS The search identified 980 publications. Of these, 200 papers were removed before screening (duplicates, non-English literature, and publication year before 2000) and 245 records were excluded after title/abstract screening. Finally, 50 articles were included in the final analysis. We analyze the latest evidence on the genetic basis of PCa predisposition and clinical implications for more personalized screening protocols and therapeutic management of this high-prevalent cancer. DISCUSSION Emerging data show that germline mutations in homologous recombination genes (BRCA1/2, ATM, CHECK2), in mismatch repair genes (MLH1, MLH2, MSH6), and other additional genes are associated with the development and aggressiveness of PCa. Germline testing and genetic counseling have increasingly important implications in cancer screening and therapeutic decisions making for patients affected by PCa. Patients with localized PCa and some gene mutations are more likely to develop aggressive cancer, so active treatment may be preferable to active surveillance for these patients. Moreover, in patients with metastatic PCa, these gene alterations may be useful biomarkers for predicting response to specific therapy such as PARP inhibitors, recently approved for the treatment of metastatic castration-resistant PCa. The evidence supports recent guidelines and recommendations considering germline genetic testing for patients with a positive family history of PCa or men with high risk or metastatic disease.

Diagnosis of prostate cancer with magnetic resonance imaging in men treated with 5-alpha-reductase inhibitors. World J Urol 2023; 41:2967-2974. [PMID: 37787941 PMCID: PMC10632288 DOI: 10.1007/s00345-023-04634-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Accepted: 09/14/2023] [Indexed: 10/04/2023] Open
Abstract
PURPOSE The primary aim of this study was to evaluate if exposure to 5-alpha-reductase inhibitors (5-ARIs) modifies the effect of MRI for the diagnosis of clinically significant Prostate Cancer (csPCa) (ISUP Gleason grade ≥ 2). METHODS This study is a multicenter cohort study including patients undergoing prostate biopsy and MRI at 24 institutions between 2013 and 2022. Multivariable analysis predicting csPCa with an interaction term between 5-ARIs and PIRADS score was performed. Sensitivity, specificity, and negative (NPV) and positive (PPV) predictive values of MRI were compared in treated and untreated patients. RESULTS 705 patients (9%) were treated with 5-ARIs [median age 69 years, Interquartile range (IQR): 65, 73; median PSA 6.3 ng/ml, IQR 4.0, 9.0; median prostate volume 53 ml, IQR 40, 72] and 6913 were 5-ARIs naïve (age 66 years, IQR 60, 71; PSA 6.5 ng/ml, IQR 4.8, 9.0; prostate volume 50 ml, IQR 37, 65). MRI showed PIRADS 1-2, 3, 4, and 5 lesions in 141 (20%), 158 (22%), 258 (37%), and 148 (21%) patients treated with 5-ARIs, and 878 (13%), 1764 (25%), 2948 (43%), and 1323 (19%) of untreated patients (p < 0.0001). No difference was found in csPCa detection rates, but diagnosis of high-grade PCa (ISUP GG ≥ 3) was higher in treated patients (23% vs 19%, p = 0.013). We did not find any evidence of interaction between PIRADS score and 5-ARIs exposure in predicting csPCa. Sensitivity, specificity, PPV, and NPV of PIRADS ≥ 3 were 94%, 29%, 46%, and 88% in treated patients and 96%, 18%, 43%, and 88% in untreated patients, respectively. CONCLUSIONS Exposure to 5-ARIs does not affect the association of PIRADS score with csPCa. Higher rates of high-grade PCa were detected in treated patients, but most were clearly visible on MRI as PIRADS 4 and 5 lesions. TRIAL REGISTRATION The present study was registered at ClinicalTrials.gov number: NCT05078359.

Abstract
OBJECTIVES The aim of this study is to investi-gate the association between the urinary metabolic milieu and kidney stone recurrence with a validated papillary evaluation score (PPLA). MATERIALS AND METHODS We prospectively enrolled 30 stone for-mers who underwent retrograde intrarenal surgery procedures. Visual inspection of the accessible renal papillae was performed to calculate PPLA score, based on the characterization of ductal plugging, surface pitting, loss of papillary contour and Randall's plaque extension. Stone compositions, 24h urine collections and kidney stone events during follow-up were collected. Relative supersaturation ratios (RSS) for calcium oxalate (CaOx), brushite and uric acid were calculated using EQUIL-2. PPLA score > 3 was defined as high. RESULTS Median follow-up period was 11 months (5, 34). PPLA score was inversely correlated with BMI (OR 0.59, 95% CI 0.38, 0.91, p = 0.018), type 2 diabetes (OR 0.04, 95% CI 0.003, 0.58, p = 0.018) and history of recurrent kidney stones (OR 0.17, 95%CI 0.04, 0.75, p = 0.019). The associations between PPLA score, diabetes and BMI were not confirmed after excluding patients with uric acid stones. Higher PPLA score was associated with lower odds of new kidney stone events during follow-up (OR 0.15, 95% CI 0.02, 1.00, p = 0.05). No other significant correla-tions were found. CONCLUSIONS Our results confirm the lack of efficacy of PPLA score in phenotyping patients affected by kidney stone disease or in predicting the risk of stone recurrence. Larger, long-term studies need to be performed to clarify the role of PPLA on the risk of stone recurrence.

Abstract
Laser technology has been used in Urology since the 80s with a lot of different applications in endoscopic and open surgery. With the developments of the technology and the introduction of new active medium and source of laser energy, this technology have become the gold standard not only in stone surgery but even in benign prostate enlargement (BPE) surgical treatment. Regarding urologic oncology, laser energy has now reached an important role in focal therapy and in conservative treatment. The possibility of having better functional outcomes without any relevant impact on oncological results led to an increased use of laser in penile surgery, with a significant mention in urological guidelines for this option. In urothelial cancers as well, both in conservative management of upper tract tumors that in the treatment of non muscle invasive bladder cancer, a clear role of these relatively new source of energy have been demonstrated. Finally, both in prostate that in renal cancer the strategy of focal therapy may take advantage from this precise and fine technology. In this review we analyzed and described the applications of laser energy in urological cancers with a specific focus on penile, urothelial and prostate cancer.

Abstract
Robot-assisted radical prostatectomy (RARP) is the most adopted treatment for localized prostate cancer. The aim of this study was to explore the learning curves (LC) for overall and site-specific positive surgical margins (PSM) occurrence after RARP of multiple surgeons within a step-structured mentor-initiated training program. The study included consecutive patients undergoing RARP between January 2013 and March 2020, by three surgeons: a mentor and his two trainees. Prospectively collected patients' data were retrospectively analyzed. The cumulative summation (CUSUM) method was used to generate the LCs, with turning points indicating the number of cases to reach proficiency levels. Furthermore, the association between PSM and surgical experience was evaluated, adjusting for case mix. A total of 761 consecutive patients were included, 370 treated by the Mentor surgeon, 247 and 144 treated, respectively, by the two Trainees. Mentor and Trainees had similar PSM rates (31.6% vs 28.0% vs 31.3%, p = 0.6). CUSUM charts showed different LC shapes for different PSM locations (postero-lateral, bladder neck, apex, and multifocal/> 3 mm). Surgical experience was significantly associated with overall, postero-lateral, and multifocal/> 3 mm PSMs, in the Mentor series only. Trainees reached their turning points after far fewer cases then the Mentor, both for overall (12 and 31 vs 153), postero-lateral (24 and 30 vs 120), and multifocal/> 3 mm PSMs (9 and 31 vs 153). The achievement of stable SM proficiency takes involved different LCs depending on the prostatic location being considered. Monitoring site-specific LC can indicate the surgical steps for which there may be still room for further technical refinements, even when an apparent proficiency status seems achieved.

Abstract
PURPOSE The knowledge of periprostatic nerve fiber (pNF) is still incomplete by means of conventional MRI. The purpose of our study was to demonstrate if DTI imaging is able to depict anatomical features of pNF. METHODS For this retrospective study, fifty-six patients (mean age 63.5 years), who underwent 1.5-T prostate MRI, including 32 directions DTI, were enrolled between October 2014 and December 2018. ANOVA test and Student's t-test were performed between the mean values of the number, FA values, and fiber length of pNF between base and mid-gland, mid-gland and apex, base and apex, right and left side, and anterior and posterior face of the prostate. A qualitative analysis was performed to detect the main orientation of pNF through a colorimetric 3D tractographic reconstruction. RESULTS The number of pNF showed a decrease from the base (322) to mid-gland (248) and apex (75) (p < 0.05). The FA values were higher at base and mid-gland (0.435 and 0.456) compared to the apex (0.313) (p < 0.05). The length of pNF was higher at apex (13.4 mm) compared to base (11.5 mm) and mid-gland (11.7 mm) (p < 0.05). The number of pNF was higher on the posterior face compared to the anterior face at base (186 vs 137), (p < 0.001). The FA values were higher on the posterior face compared to the anterior face at base (0.452 vs 0.417), mid-gland (0.483 vs 0.429), and apex (0.42 vs 0.382), (p < 0.05). The length of the pNF was higher in the posterior (14.7 mm) than in the anterior face (12 mm) at apex (p < 0.001). The main orientation of pNF was longitudinal in all patients (56/56, 100%). CONCLUSIONS DTI imaging has been demonstrated able to depict anatomical features of pNF.

Abstract
PURPOSE To investigate possible renal damage in healthy men exposed to extreme hypobaric hypoxia, using urinary Neutrophil Gelatinase-Associated Lipocalin (NGAL) concentration as biomarker. The value of NGAL as a biomarker of proximal tubular cell damage under hypoxic conditions was also tested in vitro experiments. METHODS NGAL was assayed in a cohort of air cadets (n = 16) exposed to hypobaric hypoxia in a hypobaric chamber during their training program. In all subjects, urine creatinine (Cr) and urinary NGAL levels were measured immediately before, 3, and 24 h after hypobaric environment exposure. Three in vitro experiments using proximal tubular cell cultures were also performed to measure NGAL gene expression, NGAL secretion in the culture medium and to evaluate apoptosis under two cycles of hypoxia and reoxygenation. RESULTS In the in vivo study, geometric means of urinary NGAL/Cr ratio measured 24 h after hypobaric hypoxia in the hypobaric chamber were significantly lower than baseline values (13.4 vs 25.9 ng/mg, p = 0.01). In cell cultures, hypoxia down-regulated NGAL gene expression without significantly changing NGAL secretion in the culture medium. Hypoxia significantly increased the percentage of apoptotic/necrotic cells, especially after the second hypoxia-reoxygenation cycle. CONCLUSIONS Exposure to hypobaric-hypoxic environments does not cause significant and irreversible renal tubular injury in vivo and in vitro, except than in a late stage. The hypoxic insult does not seem to be mirrored by an increase of urinary NGAL in healthy men nor of NGAL gene expression in HK-2 cell culture or secretion in the culture medium in the in vitro conditions reported in the present study.

Abstract
The treatment of renal cancer has changed in the last decades with an increase in application of conservative surgery such as partial nephrectomy (PN) in order to achieve an optimal oncological outcome with the maximum preservation of renal function. The indication for PN is mandatory in case of bilateral tumors or in case of impaired renal function. Renal artery (RA) aneurysm (RAA) is a rare occurrence, and its treatment could be radiological or surgical according to the anatomy of the aneurysm and the clinical characteristics of the patients. Here, we report a case of simultaneous ipsilateral occurrence of renal cancer and RAA in a patient with bilateral renal masses, treated with 1 surgical procedure with good functional and oncological outcomes. This rare occurrence must be known by surgeons treating renal cancers, and it is possible to perform the 2 procedures in 1 surgical step.

Abstract
INTRODUCTION In cases of recurrent high-risk non-muscle-invasive bladder cancer, radical cystectomy (RC) is recommended. We compared oncologic and treatment-related outcomes of second-line conservative device-assisted therapy to RC. PATIENTS AND METHODS In a retrospective cohort study, we analyzed 209 consecutive patients with recurrent bacillus Calmette-Guérin-unresponsive high-risk non-muscle-invasive bladder cancer; 107 subjects refused RC and were offered electromotive drug administration (n = 44) or chemohyperthermia (n = 63) (group A), and 102 patients underwent RC (group B). In group A, patients who did not benefit from device-assisted treatment underwent RC. The endpoints were high-grade disease-free survival, progression-free survival, cancer-specific survival, overall survival, and treatment-related complications. Follow-up was based on international guideline recommendations. Analyses were performed with log-rank and Fisher exact tests. RESULTS The median follow-up was 59 months (SD ± 5.3). When comparing group A to B, overall survival rates were 91.6% and 90.2%, respectively (P > .05); cancer-specific survival was 94.4% and 96.1%, respectively (P > .05); high-grade disease-free survival was 43% and 74.5%, respectively (P < .05); and progression-free survival was 59.8% and 75.5%, respectively (P < .05). Patients with carcinoma-in-situ had worse oncologic outcomes compared to patients with papillary disease. In the multivariate analysis, multifocality, disease recurrence, and progression risk group were independently associated with device treatment failure. The 90-day RC-related overall complications rates were 63.9% in group A and 66.6% in group B (P = .63); grade 3 to 5 complications were 9.8% in group A and 9.8% in group B(P = .99). Complications within group A were comparable (P > .05). CONCLUSION Device-assisted treatment may a represent a valid second-line conservative tool in selected patients with recurrent high-risk non-muscle-invasive bladder cancer.

Abstract
Introducción y objetivos Nuestro objetivo fue evaluar el impacto de la enfermedad del coronavirus de 2019 (COVID-19) en los ingresos en los servicios de urgencias (SU), las hospitalizaciones y el manejo clínico de los pacientes con urolitiasis. Pacientes y métodos Realizamos un análisis retrospectivo multicéntrico de las admisiones en los servicios de urgencias de tres departamentos de urología de gran volumen (uno directamente implicado en el tratamiento de los pacientes de COVID-19 y dos no implicados) en Roma (Italia) entre marzo y abril de 2020 y en el mismo período de 2019. Se realizó un análisis estadístico del número de admisiones por urolitiasis, la tasa de complicaciones, hospitalización y el tipo de tratamiento recibido. Resultados Fueron incluidos 304 pacientes en el análisis. Se observó una reducción significativa en el número global de pacientes ingresados en urgencias por urolitiasis entre 2019 y 2020 (48,8%). Además, con respecto a la elección del tratamiento de los pacientes hospitalizados, se informó un aumento estadísticamente significativo de los procedimientos de extracción de cálculos en comparación con el drenaje urinario en 2020 (p = 0,015). Conclusiones Durante la pandemia de la COVID-19 en Roma ha habido una reducción significativa de los ingresos en urgencias por urolitiasis. Los pacientes ingresados en el SU tuvieron más complicaciones, necesitaron hospitalización con más frecuencia y en cuanto al manejo clínico, se prefirió la extracción temprana de los cálculos, en vez del drenaje urinario. Todos los urólogos deben ser conscientes de que en los próximos meses podrían enfrentar un mayor número de admisiones por urolitiasis y un manejo de casos más complicados.

Abstract
Background and Aims
Nephrolithiasis is a medical condition characterized by high prevalence among the general population both in Europe and in the U.S. and it is responsible for high costs reaching up to $10 billion per year. It is associated with specific comorbidities such as obesity, arterial hypertension, diabetes mellitus, metabolic syndrome and chronic kidney disease.
Kidney stones development is believed to start either from Randall’s plaques or from stone plugs. Both these lesions can be seen on renal papillary surfaces, but what promotes the formation of plaques and plugs is not entirely understood.
The aim of this study is to investigate the association between the urinary metabolic milieu and a published endoscopic papillary evaluation score (PPLA). We also evaluated the correlation of PPLA score with kidney stone recurrence during follow-up.
Method
We prospectively enrolled 31 stone forming patients who undergone retrograde intrarenal surgery procedures. Visual inspection of the accessible renal papillae was performed in order to calculate the PPLA score based on the appearance of ductal plugging, surface pitting, loss of papillary contour and Randall’s plaque extension.
Demographic information, blood samples, 24h urine collections and kidney stone events during follow-up were collected. Stone composition was analyzed using infrared-spectroscopy. Relative urinary supersaturations (RSS) for calcium oxalate (CaOx), calcium phosphate (CaPi) and uric acid (UA) were calculated using the Equil2 software. PPLA score > 3 was defined as high.
Results
Median follow-up period was 11 (min/max 5, 34) months. PPLA score was inversely correlated with BMI (rho = −0.39, p = 0.035) and history of recurrent kidney stones (median PPLA 5.0 vs 2.5, p = 0.029), these results were confirmed when PPLA was considered as a categorical variable (median BMI 27 vs 24, recurrent stone disease 12 vs 62%, p= 0.006). Furthermore, high PPLA score was associated with lower odds of new kidney stone events during follow-up (OR 0.154, 95% confidence interval 0.024, 0.998, p = 0.05). No significant correlations were found between PPLA score, stone composition, blood parameters, 24h urine solute excretions and RSS for CaOx, CaPi and UA.
Conclusion
Different papillary abnormalities seem to be linked to specific mechanisms of stone formation. Although data regarding PPLA score are inconsistent, it may be a valid asset for both medical and surgical management of nephrolithiasis. Larger, long-term prospective clinical studies need to be conducted to assess the validity of PPLA score system in evaluating risk of stone recurrence.

Abstract
INTRODUCTION Psychological aptitude for surgery includes all the non-technical abilities that are necessary for the surgeons. However, differently from the other careers, these skills are not considered in the selection process and their role is definitively underestimated in the field of surgery. We perform a literature review of non-technical skills for surgery to identify their role and to understand how to train and evaluate these abilities among the surgeons. RESULTS Different methods have been presented for the evaluation and training of non-technical skills for surgeons; based on the model of aviation and anesthesia a wide range of simulated scenarios have been proposed to practice these aptitudes and abilities. Different behavioral markers systems have been developed for correct identification and definition of these skills, these can be used in the real surgical room and even learned and trained in the simulated operating theatre. CONCLUSION This article shows the importance of non-practical abilities in the surgical performance and in defining the aptitude for surgery. Learning these skills and introducing them in surgical education can be useful to improve the surgical performance.

Abstract
BACKGROUND Mitomycin C (MMC) is widely used, but the optimal dose and schedule have not been established. OBJECTIVE To evaluate the ablative power and patient safety of a short-term intensive schedule of intravesical MMC in patients with recurrent non-muscle-invasive bladder cancer (NMIBC). DESIGN, SETTING, AND PARTICIPANTS This was a prospective, single-center, nonrandomized study that compared 47 patients (group 1) with a history of low- to intermediate-risk NMIBC with long free-recurrence intervals, recurrence of ≤1cm in maximum diameter, and negative cytology to 47 consecutive patients with the same baseline characteristics (group 2). INTERVENTION Intravesical MMC three times per week for 2 wk for group 1. Transurethral resection of bladder tumor (TUR-BT) and early instillation and a weekly schedule of intravesical MMC for group 2. All cancer-free patients underwent monthly MMC maintenance. Follow-up included bladder mapping, voiding and washing urinary cytology, TUR of suspected area, TUR of previous tumor location, and ultrasound or computed tomography/magnetic resonance imaging. OUTCOME MEASUREMENT AND STATISTICAL ANALYSIS We used χ2 and Student's t test for comparison of categorical and continuous variables, respectively. Kaplan-Meier curves were plotted to estimate cancer-free survival. The significance level was set to p<0.05. RESULTS AND LIMITATIONS The complete response rate at 39 mo was 61.7% in group 1 and 70.2% in group 2 (p=0.38). Kaplan-Mayer analysis revealed no difference in cancer-free survival rates overall (log-rank <3.84), according to tumor size in each group (log-rank <3.84), or between the groups (log-rank <7.82). No cases of systemic toxicity were observed. Local toxicities did not differ between the groups (p=0.32) and resolved on treatment of symptoms, and no patient discontinued their treatment. Limitations include the small number of patients, selection bias because of the single tertiary center, and short follow-up. CONCLUSIONS The proposed MMC schedule had good ablative power that can be explained by better concordance between the scheduled timing and the tumor cell duplication rate. The short-term intensive schedule could be considered as a therapeutic strategy to replace TUR-BT in selected NMIBC patients. PATIENT SUMMARY We report our experience of a tailored intravesical therapy schedule for bladder cancer. This schedule could be considered a therapeutic strategy to replace surgery for selected patients.

Abstract
Mutations of the CYP24A1 gene are associated with alterations in the activity of the enzyme 25-OH-D-24-hydroxylase, resulting in dysfunction of the metabolism of vitamin D. This enzymatic deficiency may cause hypercalcemia, low parathyroid hormone levels, hypercalciuria, nephrolithiasis and nephrocalcinosis. The clinical case of a young woman with recurrent renal lithiasis, hypercalcemia and hypercalciuria is described. These features are linked to deficiency of the enzyme 25-OH-D-24-hydroxylase, therefore to a biallelic mutation of the CYP24A1 gene.

Abstract
OBJECTIVES To evaluate the efficacy and safety of a tailored endovesical immunotherapy protocol with biweekly BCG for elderly Patients with high risk non muscle invasive bladder cancer (HG-NMIBC). MATERIALS AND METHODS We retrospectively evaluated data from 200 patients older than 80 years newly diagnosed with HG-NMIBC: 100 (group 1) with multiple comorbidities (WHO PS 2-3, ASA score ≥3, Charlson Comorbidity index ≥3, GFR<60 mL/min) were treated with BCG induction course administered biweekly; 100 (group 2) with statistically significant better conditions were treated with standard weekly BCG therapy. After the induction treatment disease-free patients underwent to at least one year of BCG maintenance therapy. Endpoints were: initial response to BCG, cancer-free survival and rate of progression at 2 years, rate of complications. RESULTS No statistically significant differences were found in terms of initial response to BCG (69% in Group 1 vs 71% in Group 2, P = 0.75), cancer free survival (57% vs 55% respectively, P = 0.77) and rate of progression (20% vs 14% respectively, P = 0.26) at 2 years. The difference in the rate of overall complications was statistically significant (15% in Group 1 vs 27% in Group 2, P = 0.03), in the rate of severe complications was not statistically significant (5% in Group 1 vs 7% in Group 2, P = 0.61). CONCLUSION A tailored regimen of BCG administration is possible and safe in frail elderly patients, limiting side effects and risk of undertreatment but maintaining oncological outcomes. Preliminary results in a small patients group are promising but larger randomized studies are needed to confirm our data.

Abstract
MATERIALS AND METHODS The study was conducted from December 2011 to December 2012 on 95 patients between the ages of 20 and 65 years: 44 of which had been undergoing dialysis for over a year and 51 of whom had undergone kidney transplants more than 6 months before. Comorbidities were carefully recorded, erectile function was evaluated the with IIEF5 questionnaire and serum levels of total testosterone / free and prolactin were tested at early morning (7 AM). To assess the relationship between erectile dysfunction (ED) and clinical laboratory tests, Student's t-test statistical (quantitative variables), chi-square (qualitative variables), the uni and multivariate analysis were used. RESULTS In patients undergoing dialysis and in recently transplanted patients a higher instance of ED was found (70% and 65% of cases respectively). Amongst dialyzed patients, patients aged over 50 suffer from ED more frequently. Patients aged over 50s represent 61% of the total number of patients suffering from ED, and just 31% of patients not suffering from ED, (p = 0.006); Hyperprolactinemia was found in 23% and 20% of both groups respectively. Fifty nine % of the dialyzed patients presented values of testosterone serum levels of less than 250 ng/dl with a significant difference between those who were suffering from ED and those who were not (65% of ED patients vs. 46%,of patients not affected from ED p = 0.019). This was found in only 37% of transplanted patients and there does not appear to be a statistically significant correlation with the onset of ED (p = 0.12). In patients over the age of 50, diabetes and a condition of hypotestosteronemia were significantly correlated with ED at univariate and multivariate analyses. CONCLUSIONS The ED in patients with end stage chronic kidney failure (CKF) continues to have a strong prevalence, either in the patients who are undergoing dialysis or in those who have received transplants. In literature this issue is not sufficiently considered if not at all. Hypotestosteronemia is a risk factor for the onset of ED in end stage CKF patients. A significantly lower prevalence of hypogonadism among dialyzed patents and transplant recipients suggests that renal transplantation may be protective for the sexual capabilities of these patients.

Abstract
Sebaceous gland tumours represent the third most common skin tumours in dogs, but diagnostic criteria for tumours with basal differentiation (i.e. sebaceous epithelioma) are poorly defined and there is lack of correlation with biological behaviour. The aim of this study was to identify the main histological criteria associated with malignancy in 30 canine sebaceous gland tumours with a predominant reserve cell population. For each case, tumour proliferative activity was assessed by determining mitotic index and the Ki67/MIB-1 index. Additional histological features included endophytic or exophytic growth, proportion of reserve/intermediate/mature cells, connection to the epidermis, nuclear characteristics, peripheral invasion, neoplastic emboli and necrosis. Mitotic and Ki67 indexes were variable, but correlated (R = 0.66; P < 0.001), and both were significantly higher in infiltrative tumours (P = 0.018 and P < 0.001, respectively). No significant difference in histological features was observed between tumours comprised of more or less than 90% reserve cells, nor among tumours showing proliferative activity in sebocytes. This study suggests that high proliferative activity and peripheral invasion should be considered the most significant parameters for the differentiation between benign and malignant sebaceous gland tumours. Furthermore, the incidence of circumanal gland and testicular tumours in these dogs was significantly higher compared with an age-matched control population, suggesting a potential androgen-related pathway for the tumourigenesis of canine sebaceous gland neoplasms.

Abstract
BACKGROUND AND PURPOSE There is an increasing interest in new risk factors for ischaemic stroke. Acute and chronic infections could contribute to different aetiological mechanisms of atherosclerosis that lead to cerebrovascular disease. The aim of this study was to investigate the hypothesis that previous infections and Chlamydia pneumoniae in particular increase the risk of ischaemic stroke in the population. METHODS This was a prospective case-control study involving 11 Italian stroke units. Controls were age- and sex-matched with cases, represented by patients admitted to hospital for acute ischaemic stroke. For each participant classical vascular risk factors and previous inflammatory and infectious events up to 1 month before were registered. Blood samples were collected to analyse inflammatory markers and titres of antibodies against C. pneumoniae. RESULTS A total of 1002 participants were included (mean age 69 years) with 749 ischaemic stroke patients. Infections occurred within 1 month previously in 12% of the entire sample with a higher prevalence in the case group (14.4% vs. 3.9%). At multivariate analysis of the seropositivity of IgA antibodies against C. pneumoniae increased the risk of stroke significantly (relative risk 2.121; 95% confidence interval 1.255-3.584) and an early previous infection (up to 7 days before the event) contributed to a rise in probability of acute cerebral ischaemia (relative risk 3.692; 95% confidence interval 1.134-6.875). CONCLUSIONS Early previous infections and persistent chronic infection of C. pneumoniae could contribute to increase the risk of ischaemic stroke significantly, in the elderly especially.

Abstract
INTRODUCTION Radical surgery is the "gold standard" for treatment of invasive penile carcinoma but very poor aesthetic, functional and psychological outcomes have been reported. Our purpose was to assess the impact of organ potency-sparing surgery in locally confined carcinoma of the penis. MATERIALS AND METHODS We evaluated retrospectively 42 patients with early penile cancer (Ta,T1,T2), treated with glandulectomy and glanduloplasty with urethral mucosa and sparing of cavernosal apexes, or glandulectomy and limited apical resection in cases of Stage T2. Sexual function, ejaculation and libido were evaluated with an IIEF-15 questionnaire before the appearance of neoplasia (about three months before the surgery) and six months after surgery. Quality of life was evaluated by the Bigelow-Young questionnaire. The scores relating to two weeks prior to the surgery have been compared to those obtained six months after surgery. The statistical analysis was conducted using t-Student for repeated measures and analysis of variance. RESULTS Six months after surgery 73% of patients reported spontaneous rigid erections, 60% coital activity while 76% of the group treated with urethral glanduloplasty reported normal ejaculation and orgasm, regained an average of 35 days after surgery. The average IIEF-15 scores reported in the entire series in the domains of erection, libido and coital activity of the pre-cancer period were not statistically different than those recorded six months after surgery. In the group treated with glandular reconstruction, pre-and postoperative IIEF-15 mean scores related to ejaculation and orgasm domains were not significantly different. Mean scores of Bigelow-Young questionnaires related to sexual pleasure, familial, social and professional relationships showed significant improvement after surgery. CONCLUSIONS Potency sparing-sparing surgical treatments have a positive impact on a wide spectrum of the patient's life including family relationships, and social and working conditions.

Abstract
To identify the possible complications after extracorporeal shock wave lithotripsy (SWL) and to suggest how to manage them, the significant literature concerning SWL treatment and complications was analyzed and reviewed. Complications after SWL are mainly connected to the formation and passage of fragments, infections, the effects on renal and nonrenal tissues, and the effects on kidney function. Each of these complications can be prevented adopting appropriate measures, such as the respect of the contraindications and the recognition and the correction of concomitant diseases or infection, and using the SWL in the most efficient and safe way, tailoring the treatment to the single case. In conclusion, SWL is an efficient and relatively noninvasive treatment for urinary stones. However, as with any other type of therapy, some contraindications and potential complications do exist. The strictness in following the first could really limit the onset and danger of the appearance of others, which however must be fully known so that every possible preventive measure be implemented.

Abstract
Despite recent improvements in detection and treatment, prostate cancer continues to be the most common malignancy and the second leading cause of cancer-related mortality. Thus, although survival rate continues to improve, prostate cancer remains a compelling medical health problem. The major goal of prostate cancer imaging in the next decade will be more accurate disease characterization through the synthesis of anatomic, functional, and molecular imaging information in order to plan the most appropriate therapeutic strategy. No consensus exists regarding the use of imaging for evaluating primary prostate cancer. However, conventional and functional imaging are expanding their role in detection and local staging and, moreover, functional imaging is becoming of great importance in oncologic management and monitoring of therapy response. This review presents a multidisciplinary perspective on the role of conventional and functional imaging methods in prostate cancer staging.

Abstract
We recently identified in prostate tumors (PCa) a transcriptional prognostic signature comprising a significant number of genes differentially regulated in patients with worse clinical outcome. Induction of up-regulated genes was due to chromatin remodeling by a combinatorial complex between estrogen receptor (ER)-β and endothelial nitric oxide synthase (eNOS). Here we show that this complex can also repress transcription of prognostic genes that are down-regulated in PCa, such as the glutathione transferase gene GSTP1. Silencing of GSTP1 is a common early event in prostate carcinogenesis, frequently caused by promoter hypermethylation. We validated loss of glutathione transferase (GST) P1-1 expression in vivo, in tissue microarrays from a retrospective cohort of patients, and correlated it with decreased disease-specific survival. Furthermore, we show that in PCa cultured cells ERβ/eNOS causes GSTP1 repression by being recruited at estrogen responsive elements in the gene promoter with consequential remodeling of local chromatin. Treatment with ERβ antagonist or its natural ligand 5α-androstane-3β,17β-diol, eNOS inhibitors or ERβ small interference RNA abrogated the binding and reversed GSTP1 silencing, demonstrating the direct involvement of the complex. In vitro, GSTP1 silencing by ERβ/eNOS was specific for cells from patients with worse clinical outcome where it appeared the sole mechanism regulating GSTP1 expression because no promoter hypermethylation was present. However, in vivo chromatin immunoprecipitation assays on fresh PCa tissues demonstrated that silencing by ERβ/eNOS can coexist with promoter hypermethylation. Our findings reveal that the ERβ/eNOS complex can exert transcriptional repression and suggest that this may represent an epigenetic event favoring inactivation of the GSTP1 locus by methylation. Moreover, abrogation of ERβ/eNOS function by 3β-adiol emphasizes the significance of circulating or locally produced sex steroid hormones or their metabolites in PCa biology with relevant clinical/therapeutic implications.

Evidence for bovine besnoitiosis being endemic in Italy--first in vitro isolation of Besnoitia besnoiti from cattle born in Italy. Vet Parasitol 2011; 184:108-15. [PMID: 21978744 DOI: 10.1016/j.vetpar.2011.09.014] [Citation(s) in RCA: 53] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2011] [Revised: 07/13/2011] [Accepted: 09/05/2011] [Indexed: 11/16/2022]
Abstract
Until 2009, bovine besnoitiosis had never been considered endemic in Italy and the only report on the disease in this country referred to animals imported from France shortly before. However, recently, an autochthonous outbreak of bovine besnoitiosis was reported in four herds located at the intersection of the borders between Emilia-Romagna, Toscana and Marche (Northern Apennine Mountains), which has led to an increased awareness concerning this disease. The present study describes a further outbreak of bovine besnoitiosis in Italy. The afflicted herd was a dairy herd with no evidence for contact with cattle from regions known to be endemic for bovine besnoitiosis. The farm investigation was initiated after a three-year old Holstein Friesian dairy cow with generalized thickening and lichenification of the skin was diagnosed with bovine besnoitiosis. The clinical diagnosis was confirmed by gross pathology, histopathology, serology and PCR. Bradyzoites released from tissue cysts obtained from the skin of this animal enabled the first in vitro isolation of Besnoitia besnoiti in Italy. This isolate was named Bb-Italy1. Sequencing of a 2118 bp spanning region including the complete internal transcribed spacer 1 and parts of the 18S and the 5.8S rRNA gene from DNA extracted from skin-derived zoites revealed a 99.9% identity to sequences known for other B. besnoiti isolated from cattle in Europe. Two GKO mice which had been inoculated intraperitoneally with bovine skin-derived bradyzoites became ill 7 days post inoculation. Parasitophorous vacuoles with multiplying zoites were observed in the cell culture inoculated with peritoneal fluids of these mice and a B. besnoiti infection in the mice and in the cell culture could be confirmed by real-time PCR. A serological investigation in the afflicted herd using immunoblots and an immunofluorescent antibody test (IFAT) revealed an overall herd seroprevalence of 9.7% (31/321), whereas within the female animals older than 2 years 17.0% (29/171) of the dams were tested positive. With one exception, an imported cow from Germany, all the seropositive animals were born in Italy. In connection with previously described autochthonous cases of bovine besnoitiosis the case described herein suggests that bovine besnoitiosis should be considered endemic in Italy.

Evidence for bovine parafilariosis in Italy: first isolation of Parafilaria bovicola (Tubangui, 1934) from autochthonous cattle. Vet Parasitol 2011; 184:88-91. [PMID: 21871737 DOI: 10.1016/j.vetpar.2011.08.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2011] [Revised: 07/21/2011] [Accepted: 08/01/2011] [Indexed: 10/17/2022]
Abstract
In May and July 2010 and in March 2011, the presence of multiple bleeding nodules at the level of the neck, shoulders, withers, back and rump in five cattle from three herds in north-central Italy were observed. A diagnosis of parafilariosis was made. Fragments of adult females of Parafilaria bovicola could be identified from the derma of three to five bioptic extirpates. Larvated eggs and free larvae were observed in serohemorrhagic exudates. This paper is the first report of the occurrence of parafilariosis in Italy and subsequent to the various outbreaks reported, it can now be said that bovine parafilariosis is also currently present in Italy.
