RESUMO

Risk factors for Peyronie's disease (PD) are serum lipid abnormalities, hypertension and type 2 diabetes mellitus (T2DM). Oxidative stress and inflammation are key-players in the pathogenesis of arterial diseases, leading to insulin resistance (IR), which is a major determinant of non-alcoholic fatty liver disease (NAFLD). We studied the potential relationship between PD, IR, and NAFLD. Forty-nine male patients were enrolled, fulfilling the well-accepted diagnostic criteria of stable PD. Fifty male individuals without PD, well-matched for age and BMI, were selected as the control group. Comorbidities (T2DM and hypertension), as well as the lipid profile and the glucometabolic asset, were evaluated. The triglycerides/HDL ratio (TG/HDL-C ratio) with a cut-off of ≥3 and the triglycerides-glucose index (TyG) with an optimal cut-point of 8.5 were used for diagnosis of IR and NAFLD, respectively. NAFLD diagnosis was confirmed by the presence of bright liver at ultrasonography. Hypertension was found more frequently in PD patients than in no-PD subjects (P=0.017), independently of age (P=0.99). Both IR and NAFLD were significantly associated with the presence of PD in our population of men (P=0.043 and 0.0001, respectively), no matter how old (P=0.11 and 0.74, respectively). At logistic regression, NAFLD was the only predictor of the PD presence (p=0.021). The AUROC of TyG to predict PD was 0.7437 (sensitivity 67.35% and specificity 80%) with a percentage of correctly classified patients of 73.74%. Oxidative stress markers were significantly associated with NAFLD. Testosterone level was significantly low in the subjects with NAFLD in cross-sectional analyses. Both factors, i.e., oxidative stress and hypogonadism, are central to PD pathogenesis. In conclusion, NAFLD and IR are strongly associated with PD. The pathogenic link between these conditions and the underlying mechanisms are only hypothetical and thoroughly summarized in the discussion.

RESUMO

In 2015 bladder cancer was the fourth most frequent malignancy and the eighth cause of death for cancer. At diagnosis, about 30% of bladder cancer (BC) patients present a muscle-invasive bladder cancer (MIBC) and 5% a metastatic bladder carcinoma (MBC). For fit MBC patients, combination chemotherapy (CC) is the standard of care for first-line treatment. CC includes both the treatment with methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) either the classical or the dose-dense MVAC regimen, and the doublet therapy with cisplatin and gemcitabine (CG). Median progression free survival (PFS) was 7 months and median overall survival (OS) was 15 months. The present review provides an update on the management of MBC, with focus on target therapies, immune checkpoint inhibition, looking for prognostic and predictive factors.

RESUMO

PURPOSE: Magnetic Resonance Imaging (MRI) targeted biopsy increases overall detection rates and decreases the risk of clinically insignificant PCa detection. The aim of this retrospective study is to compare concordance rates regarding side of lesion and Gleason Score at fusion targeted/systematic biopsy and MRI with the definitive histologic report of prostatectomy specimen. METHODS: 115 patients underwent multiparametric (mp) MRI and successively fusion targeted/systematic biopsy. 107 patients, with a positive biopsy for PCa, further underwent laparoscopic/robotic radical prostatectomy. We compared surgical histologic report with biopsy histologic report for side of lesion and Gleason Score. We further compared PIRADS score at mpMRI with Gleason Score of both histologic reports. RESULTS: Concordance rate for mpMRI lesion side was 74% compared to biopsy and 52.3% compared to surgical histologic report (p < 0.0001). Fusion targeted/systematic biopsy reported a concordance rate with surgical histologic report of 67.3% for side of the lesion, while Gleason Score was concordant for 73.6% for clinically significant cancer (Gleason Score ≥ 7) (p < 0.0001). PIRADS score ≥ 3 was further associated with clinically significant cancer at surgical histologic report in 92.4% of cases (p = 0.359). CONCLUSION: Multiparametric MRI of the prostate reaches a good and improvable accuracy in the detection of suspicious PCa before biopsy. A combined approach of fusion targeted and systematic biopsy could further increase the overall accuracy in PCa diagnosis, especially in biopsy-naïve patients, reaching concordance rates with definitive histologic report up to 52.3% and 85.5%.

RESUMO

OBJECTIVE: Testicular cancer is a relatively rare neoplasia, with an incidence of about 1,5% among male malignancies, usually in the third and fourth decade of life. Although several histological variants are known, with some histotypes affecting older patients (e.g., spermatocytic seminoma), there is a clear predominance (90-95%) of germ cell tumors among young adults patients1. Testicular Germ Cell Tumor (TGCT), undoubtedly the seminoma histological variant more than non-seminoma one, is definitely a highly curable disease, with a distinctive sensitivity to cisplatin-based therapy (and for seminomas to radiotherapy) and an outstanding cure rate of nearly 80% even for patients with advanced disease. So far, clinical and pathohistological features supported our efforts to choose the best treatment option for patients suffering from this malignancy, but we don't clearly enough know molecular and pathological features underlying different clinical behaviors, mostly in early-stage disease: by improving this knowledge, we should better "shape" therapeutic or surveillance programs for each patient, also in order to avoid unnecessary, if not harmful, treatments.

RESUMO

BACKGROUND: Couple distress is a crucial point in premature ejaculation (PE). PE has been associated with significant bother, interpersonal problems, and dissatisfaction with sexual intercourse for both men and their partners. OBJECTIVES: The primary objective of this study was to assess the effect of PE on female sexuality in female partners of men affected from PE. Secondary objectives were to assess the impact of PE on female sexual quality of life, to assess the presence of sexual problems of the male partner, and to evaluate the prevalence and characteristics of comorbidities. MATERIALS AND METHODS: Adult women aged 18 to 80 years old, sexually active, were randomly sampled from the patient lists of General Practitioners in Italy and were included in this observational, non-interventional, cross-sectional epidemiological study. Subjects were asked to fill: a general questionnaire regarding anthropometric data, lifestyle, marital status, education, occupation, economic conditions, general health status, comorbidities, and sexual habits; the Sexual Quality of Life Questionnaire-Female (SQoL-F); the Female Sexual Distress Scale (FSDS-R-PE); the Self-rating Depression Scale (SDS); and Self-rating Anxiety Scale (SAS). In addition, females reported about their partner's ejaculation time and the presence of sexual dysfunctions. RESULTS: A total of 3,104 women were included. Mean age was 45.1 years. Woman with PE partners presented a higher percentage of sexual dysfunction and reported more anxiety compared with female partners of men not affected from PE (42.69% vs. 20.56% and 30.95% vs. 15,34%, respectively). In addition, they referred more sexual dysfunction in their partners. Hypertension, hypercholesterolemia, arthritis, heart diseases, thyroid disease, a history of menopause, or hysterectomy resulted in significantly more prevalence in women with PE partners. DISCUSSION AND CONCLUSIONS: Female partners of PE patients present an increased prevalence of sexual distress, a reduced quality of sexual life, and an increased anxiety score when compared to women whose partners are not affected from PE.

RESUMO

OBJECTIVE: In this review, we focused our attention on Quality of Life (QoL) of testicular cancer survivors (TCSs), in general and in the most relevant areas. Several key findings have been highlighted in our review. MATERIALS AND METHODS: PubMed, MEDLINE and PsycINFO databases were consulted to find published studies, from 1980 to May 2017, that met our inclusion criteria. RESULTS: The majority of studies investigated older adult TCSs, while few studies on adolescent and young adult patients were available. Many studies indicate that health-related QoL (HRQoL) is similar among the TCSs and the general population. Even if QoL deteriorates so clear at the time of diagnosis and throughout treatment, afterward returns to normal levels, as defined by the matched controls. However, there are numerous chronic conditions consequent to diagnosis and treatment of testicular cancer that plague survivors and affect QoL, like Raynaud-like phenomena, peripheral neuropathy, fatigue, anxiety, sexual, fertility and body image problems. Even if these problems can have no effects on the measures of global QoL, they have an impact on the quality of life. Differences between TCSs with and without a partner bring to different outcomes in the adjustments to cancer. CONCLUSIONS: It is necessary to identify TCSs with higher risks of poorer QoL outcomes, to focus interventions on the areas with the greatest impairments. Further researches should consider the effects of testicular cancer on the impaired areas, collecting more data to better identify survivor's needs and consequent interventions, with a special focus on adolescent and young adult TCSs. Other works are requested on therapies, preventive and ameliorative, to reduce chronic side effects of testicular cancer treatment.

RESUMO

PURPOSE: The current literature on the impact of different urinary diversions on patients' health related quality of life (HR-QoL) showed a marginally better quality of life scores of orthotopic neobladder (ONB) compared to ileal conduit (IC). The aim of this study was to update the review of all relevant published studies on the comparison between ONB and IC. MATERIALS AND METHODS: Studies were identified by searching multiple literature databases, including MEDLINE, CINAHL, the Cochrane Library, PubMed Data were synthesized using meta-analytic methods conformed to the PRISMA statement. RESULTS: The current meta-analysis was based on 18 papers that reported a HR-QoL comparison between IC and ONB using at least a validate questionnaire. Pooled effect sizes of combined QoL outcomes for IC versus ONB showed a slight, but not significant, better QoL in patients with ONB (Hedges' g = 0.150; p = 0.066). Patients with ileal ONB showed a significant better QoL than those with IC (Hedges' g = 0.278; p = 0.000); in case series with more than 65% males, ONB group showed a slight significant better QoL than IC (Hedges' g = 0.190; p = 0.024). Pooled effects sizes of all EORTC-QLQ-C30 aspects showed a significant better QoL in patients with ONB (Hedges' g = 0.400; p = 0.0000). CONCLUSIONS: This meta-analysis of not-randomized comparative studies on the impact of different types of urinary diversions on HR-QoL showed demonstrated a significant advantage of ileal ONB compared to IC in terms of HR-QoL.

RESUMO

BACKGROUND: To evaluate the correlation between the side of positive biopsy (Bx) and the risk of lymph-node metastases (LNMs) on each side and to quantify the risk of contralateral LNMs in patients with unilateral positive biopsy. METHODS: We analyzed the outcomes of 1599 patients with complete data regarding the sides of positive Bx and LN (lymph-node). By dividing each prostate into two separate sides, we assessed the accuracy of the side-specific Bx details in determining the side of positive nodes; the area under the receiver-operating characteristic (ROC) (AUCs) was used. For patients with unilateral positive Bx, we assessed the risk of homolateral and contralateral LNMs according to the number of total Bx taken and the preoperative risk of LN invasion. RESULTS: Considering the 3198 prostate sides, there was a strict correlation between the side of positive Bx and the side of LNMs. The ratio of positive/total Bx was more informative than the number of positive core. The AUC for ipsilateral LNMs was significantly higher than that for contralateral LNMs (P = 0.039). In the 805 patients with unilateral positive Bx, the percentage of contralateral LNMs was >30% even considering a more meticulous biopsy scheme and increased in the patients at a higher clinical risk for LN invasion. CONCLUSION: PCa preferentially metastasizes to ipsilateral LNs but >30% of contralateral LNMs are present. A unilateral LN dissection that is limited to the tumor-bearing side of the gland should not be recommended because of the substantial risk of missing contralateral metastases.

RESUMO

Extracorporeal shock wave therapy improves erectile function in patients with Peyronie's disease. However, erectile dysfunction still persists in many cases. We aimed to investigate the effects of extracorporeal shock wave therapy plus tadalafil 5 mg once daily in the management of patients with Peyronie's disease and erectile dysfunction not previously treated. One hundred patients were enrolled in a prospective, randomized, controlled study. Patients were randomly allocated to receive either extracorporeal shock wave therapy alone for 4 weeks (n = 50) or extracorporeal shock wave therapy plus tadalafil 5 mg once daily for 4 weeks (n = 50). Main outcome measures were: erectile function (evaluated through the shortened version of the International Index of Erectile Function), pain during erection (evaluated through a Visual Analog Scale), plaque size, penile curvature and quality of life (evaluated through an internal questionnaire). Follow-up evaluations were performed after 12 and 24 weeks. In both groups, at 12 weeks follow-up, mean Visual Analog Scale score, mean International Index of Erectile Function score and mean quality of life score ameliorated significantly while mean plaque size and mean curvature degree were unchanged. Intergroup analysis revealed a significantly higher mean International Index of Erectile Function score and quality of life score in patients receiving the combination. After 24 weeks, intergroup analysis revealed a significantly higher mean International Index of Erectile Function score and mean quality of life score in patients that received extracorporeal shock wave therapy plus tadalafil. In conclusion extracorporeal shock wave therapy plus tadalafil 5 mg once daily may represent a valid conservative strategy for the management of patients with Peyronie's disease and erectile dysfunction.

RESUMO

The aim of this trial was to compare the efficacy and safety of extended-release ciprofloxacin (CIPRO XR) versus the immediate-release formulation (CIPRO IR) in the treatment of complicated urinary tract infections (UTIs). 212 patients were randomized to CIPRO XR 1,000 mg tablet once daily or CIPROXIN IR 500 mg tablet twice daily. Treatment efficacy was evaluated by bacteriological outcome. Safety was measured by recording adverse events. The rate of bacteriological eradication was 83% in the CIPRO XR group and 75% in the CIPRO IR. the overall incidence of adverse events reported was higher in the CIPRO IR group. The authors conclude that CIPRO XR is a safe and effective treatment for complicated UTIs. Although the limited data available do not consent to support a statistically superior efficacy or safety compared to CIPRO IR, a trend in favor of CIPRO XR is clearly evident in all efficacy and safety variables. CIPRO XR is associated with reduced frequencies of drug-related adverse events compared to CIPRO IR.

RESUMO

The transsexual is a person who suffers from a deep identity disturbance caused by physical characteristics which do not correspond to mental traits and tendencies. The persistent sense of contradiction between his or her deceptive sexual appearance and his or her inner perception, causes a strong desire to achieve harmonization of the two. This aspiration, even if modification of chromosomal sex is impossible, can be fulfilled by undergoing SRS (Sex Reassignment Surgery). SRS represents the last major step of a clinical, therapeutic and diagnostic program involving skilled professionals in the physical and psychological sciences. Their assistance and counseling helps the patient to calmly and consciously decide to undergo SRS. A surgeon has the obligation not only to validate the operation outcome, but to also to maintain a long-term follow-up. A transsexual is not just like any other person; he or she should therefore be treated with sympathy and understanding. The surgeon should try his best to establish a relationship of mutual trust, taking into account the causes of anxiety and stress felt by the patient, and keeping in mind the ultimate objective, which is an improvement in the quality of life. At present, the most widely used surgical techniques are the Simple Penile Skin Inversion, the Penile-scrotal flap Inversion and the enterovaginoplasty. Each surgical technique has its own advantages and disadvantages, and it is up to the surgeon, in discussion with the patient, to make the appropriate choice. The surgical technique performing the Simple Penile Skin Inversion seems to ensure a better cosmetic appearance and an adequate lubrication, but a lower rate of satisfaction, in relation to the neocavity depth. On the contrary, the Penile-Scrotal Flap Inversion guarantees an adequate vaginal depth and lubrication, even though the cosmetic appearance is not always completely satisfactory. In our experience, a significant number of patients were satisfied with the chosen surgery and felt comfortable with their new post-operative gender. Taking into account all the complications involved, none of the patients did regret; actually, they would recommend the same operation to others. The overall results of some studies carried out on patient satisfaction before and after SRS show a marked post-surgery improvement of sexual life.

RESUMO

OBJECTIVES. Nowadays endorectal probes for Magnetic Resonance Imaging (MRI) have better resolutions, which allows to acquire high-level images of prostate and to improve the MRI sensitivity and specificity to determine the cancer volume and the extraprostatic extension. The objective of the present study is to evaluate the sensitivity and diagnostic accuracy of endorectal MRI for identifying the local extension of prostate carcinoma compared to transrectal sonography (TRUS) of prostate. MATERIALS AND METHODS. The study included 81 patients with clinical suspect of cancer and/or elevated values of serum prostate specific antigen (PSA), who underwent endorectal MRI with 1.5 T endorectal probe before transrectal biopsy. Patients with localized prostate cancer underwent radical surgery. The results of endorectal MRI were compared to those of TRUS and histopathological examination outcomes. RESULTS. 15 of the 81 enrolled patients had extraprostatic localization of cancer, which was assessed through TRUS in 4 cases only (26%), and through MRI in 7 cases (46%). A seminal vesicle involvement was present in 10 patients, detected by MRI in 5 cases and in no cases by TRUS. DISCUSSION AND CONCLUSIONS. Data are similar to the findings collected by several Authors. The endorectal MRI has a better accuracy in staging prostate cancer compared to TRUS. Nevertheless, this procedure has some limits: little availability of equipment in hospitals, physicians' little experience, and higher costs compared to TRUS.

RESUMO

Apomorphine is used in the erectile dysfunction therapy and its action has been ascribed to the stimulation of central dopamine receptor. At the present stage, very little is known about the peripheral action of apomorphine on human corpus cavernosum (HCC). We have investigated the peripheral action of apomorphine and the role of dopamine receptors in HCC. We here demonstrate that both D1 and D2 receptors were expressed in the HCC, D1 receptors were two-fold more abundant than D2 and that both receptors were mainly localized on the smooth muscle cell component. Apomorphine in vitro exerted an anti-alpha1 adrenergic activity in human cavernosal strips since it prevented contraction induced by phenylephrine (PE), but not by U46619 or endothelin. Apomorphine elicited endothelium-independent and concentration-dependent relaxation of the strips contracted by PE, U46619 or endothelin. The EC50 values (microM) for apomorphine, in the presence and absence of endothelium, were 51.0+/-16 and 16.0+/-14, 120+/-19 and 150+/-18, 59.0+/-15 and 140+/-50 on PE-, U46619- or endothelin-induced contraction, respectively. Selective dopamine receptor agonist A-68930 (D1-like), but not quinpirole (D2-like), caused concentration-dependent relaxation of the cavernosal strips, which was partially prevented by endothelium removal or by treatment with an inhibitor of nitric oxide (NO) synthase. In conclusion, we show that (1) apomorphine has a peripheral relaxant direct effect as well as an antiadrenergic activity, (2) HCC possesses more D1-like (D1 and D5) than D2-like (D2, D3 and D4) receptors, (3) both D1- and D2-like receptors are mainly localized on smooth muscle cells and (4) the relaxant activity is most probably mediated by D1-like receptor partially through NO release from endothelium.

RESUMO

Several drugs have been associated with an increased risk of erectile dysfunction (ED). We analysed the role of pharmacological treatments on the risk of ED using data from a cross-sectional study on prevalence and risk factors for ED in the general population in Italy. A total of 2450 men aged more than 18 years were randomly identified by 143 general practioners (GP) among their registered patients and invited to a confidential interview by their GP. Patients were asked 'about their ability to achieve and maintain an erection sufficient for satisfactory sexual performance'. If they were dissatisfied, they were defined as having ED. Out of the 2450 men identified, 440 (18%) refused to participate. The present analysis therefore includes information on 2010 men. After adjustment for related pathologies, anxiolytics and antidepressants showed insignificantly higher odds ratio (ORs, respectively, 1.7 and 2.1); antipsychotic drug use significantly increased the risk of ED (OR 9.0, 95% confidence interval, CI 1.8-44.4). Diuretics (OR 3.1, 95% CI 1.4-6.9) and anticholinergic drugs (OR 12.8, 95% CI 2.7-60.1) were associated with ED risk. No association emerged between ED and H2 antagonists, anticholesterolemic or hypoglycemic drugs. In conclusion, after taking account of related pathologies, our results suggest that men treated with antipsychotic, diuretic and anticholinergic drugs are at greater risk of ED.

RESUMO

Despite the importance of sexuality for both men and women of all ages, only in the last few years extensive research has been carried out into female sexual problems. It has been discovered that sexual problems affect a considerable number of women each year, and this indicates the validity and necessity of further medical studies. We know that female genital sexual response is a combination of vasocongestive and neuromuscular events in the genital tract and pelvic floor which are controlled in part by specific neurotransmitters. Other pelvi-perineal genital structures undergo vasculogenic changes, namely the labia, periurethral glands, urethra and the Halban's fascia but much less attention has been paid to the role of these tissues in sexual response compared to the clitoris and the vagina. The most common etiologies of female sexual dysfunction are vasculogenic, neurogenic, hormonal/endocrine, muscologenic. The increasing various problems of female sexual dysfunction and the interest in the matter and the subsequent research are factors which keep the scientific community involved constantly active.

RESUMO

OBJECTIVES: Pudendal nerve somatosensory evoked potentials (SEPs), the bulbocavernosus (BC) reflex, and BC perineal motor evoked potentials after transcranial magnetic cortical stimulation were performed in patients with primary premature ejaculation to investigate the somatic sensory and motor function of the genital area. METHODS: Fourteen patients with primary premature ejaculation underwent psychological counseling, urologic physical examination, transrectal ultrasound examination, laboratory testing, and the Stamey test. The spinal and cortical pudendal nerve SEPs were performed by dorsal nerve stimulation at the penile shaft (DN-SEPs) in all patients and at the glans penis (GP-SEPs) in 3 of them. The BC reflex was obtained by stimulating the base of the penis. RESULTS: The mean sensory threshold did not significantly differ between the patients and normal subjects. Cortical DN-SEPs were normal in all patients. The sensory central conduction time, calculated in 6 patients, was normal. The mean cortical DN-SEP amplitude was significantly smaller in patients than in controls. In 3 patients and in 3 controls who underwent both DN-SEP and GP-SEP testing, the glans penis sensory threshold was lower than the dorsal nerve threshold and the cortical GP-SEP latency was longer than the cortical DN-SEP latency. The BC reflex was normal in most patients. The BC motor evoked potentials were normal in all patients, but one. CONCLUSIONS: We did not confirm either a faster conduction along the pudendal sensory pathway or a greater cortical representation of the sensory stimuli from the genital area in our patients. Moreover, we did not confirm hyperexcitability of the BC reflex in them. Our results suggest that the electrophysiologic approach is probably not sufficient to clarify the causes of primary premature ejaculation. A more integrated investigation could allow better results in this field.
