Erectile Dysfunction and Methadone Maintenance Therapy

Erectile dysfunction is one of the most common side effects of methadone affecting more than half of methadone patient population. The problem is associated with prominent reduced quality of life. Erectile dysfunction may perpetuate greater problem if left untreated as patients may opt to use harmful self-treatment such as abusing methamphetamine. This illicit drug use to overcome the side-effects of methadone may lead to polysubstance use disorder that further compromise addiction therapy. To overcome this issue, both practitioners and patients play a major role in the management of erectile dysfunction. Patient awareness regarding erectile dysfunction and its impact as well as doctor’s active intervention to detect erectile dysfunction, are essential to improve the detection rate and management of erectile dysfunction. Frequent screening of erectile dysfunction and its risk factors will help with the identification of patients suffering from erectile dysfunction. Multiple treatments options such as bupropion, trazodone and many more are available to treat erectile dysfunction which will be further explored in this review.

Focal therapy with high-intensity focused ultrasound for the localized prostate cancer for Asian based on the localization with MRI-TRUS fusion image-guided transperineal biopsy and 12-cores transperineal systematic biopsy: prospective analysis of oncological and functional outcomes.

We evaluated clinical outcomes of region target focal therapy with high-intensity focused ultrasound (HIFU) for the localized prostate cancer (PCa) based on magnetic resonance imaging-based biopsy and systematic prostate biopsy for Asian. We prospectively recruited patients with localized PCa, located their significant tumors using MRI-transrectal ultrasound (TRUS) elastic fusion image-guided transperineal prostate biopsy and 12-cores transperineal systematic biopsy, and focally treated these regions in which the tumors were located in the prostate using HIFU. Patients' functional and oncological outcomes were analyzed prospectively. We treated 90 men (median age 70years; median PSA level 7.26ng/ml). Catheterization was performed within 24h after the treatment in all patients. Biochemical disease-free rate was 92.2% during 21months follow-up when use of Phoenix ASTRO definition. In follow-up biopsy, significant cancer was detected in 8.9% of the patients in un-treated areas. Urinary functions, including international prostate symptom score (IPSS) (P < 0.0001), IPSS quality of life (QOL) (P = 0.001), overactive bladder symptom score (OABSS) (P < 0.0001), EPIC urinary domain (P < 0.0001), maximum urinary flow rate (P < 0.0001), and IIEF-5 (P = 0.001), had significantly deteriorated at 1month after treatment, but improved to preoperative levels at 3 or 6months. Rates of erectile dysfunction and ejaculation who had the functions were 86% and 70%, respectively, at 12months after treatment. The present treatment for Asian would have similar oncological and functional outcomes to those in previous reports. Further large studies are required to verify oncological and functional outcomes from this treatment for patients with localized PCa.

Techniques and Outcomes of Salvage Robot-Assisted Radical Prostatectomy (sRARP)

BackgroundSalvage Robot-Assisted Radical Prostatectomy (sRARP) has been described as feasible treatment for the management of localised prostate cancer (PCa) recurrence after primary treatment. However, no large reports have published cancer and quality outcomes. ObjectiveTo report perioperative, functional and oncologic outcomes of sRARP in patients with localised PCa recurrence. Design, Setting, and ParticipantsWe retrospectively evaluated 106 patients with local recurrence eligible for sRARP. Surgical ProcedureSurgery was performed using the DaVinci Si system similar to the standard approach but with adaptation to the primary treatment. MeasurementsPeri-operative outcomes included 90-day complication rate. Functional outcomes included rates of incontinence and erectile dysfunction. Oncological outcomes included tumour staging, margin rate and recurrence. Results and LimitationsPrimary treatment was High Intensity Focused Ultrasound (HIFU) in 59 (56%) patients, 27 (25%) radiotherapy, 10 (9%) seed brachytherapy, 8 (8%) solitary androgen deprivation therapy (ADT), one (1%) cryotherapy and one (1%) electroporation / Nanoknife. Median follow-up was 2.1 years. 90-day complication rate was 8%. At two years or more, 50% were fully continent and 33% were socially continent. Continence rates tended to be better after focal compared to whole-gland treatments. Erectile dysfunction was present in 95%. Positive surgical margin rate was 39%. Biochemical recurrence occurred in 13% and local or metastatic recurrence in 11%. ConclusionssRARP is technically more challenging but is a feasible option in high-volume centres for treatment of recurrent PCa. Patients should be counselled that functional outcomes are inferior to primary RARP. Adjustment of surgical technique according to the primary treatment is key for good surgical outcomes. Patient SummaryWe report our experience with sRARP for the management of localised PCa recurrence after primary treatment. This represents a feasible approach with acceptable peri-operative complications and cancer outcomes. Functional outcomes are inferior to RARP in the primary setting.

Sexual dysfunction in men with type II diabetes.

Background:Diabetes mellitus (DM) is a chronic disease inducing short-term and long-term complications including sexual dysfunction (SD) which can consequently reduce patients’ quality of life. Given the limited literature on frequency of SD in men experiencing diabetes in northern Iran, the present study was conducted in the city of Sari in Mazandaran Province, with the aim of investigating SD in men with type II diabetes.Methods:Using a descriptive cross-sectional research design, a total number of 350 male patients suffering from type II diabetes referring to endocrinology clinics in the city of Sari in. The patients were requested to fill out the demographic questionnaire, depression, anxiety and stress scale-21 items (DASS-21) and the 15-question International Index of Erectile Function (IIEF). The data were analyzed using the IBM SPSS statistics software Results:The average period of time in which the patients were facing diabetes was 3.65±5.75 years. The IIEF mean score was equal to 16.98±43.79. Erectile dysfunction (ED) was also evident in 152 patients (62.2%). Moreover, increase in age had significantly decreased the IIEF scores (p<0.001). The chance of being affected with ED among diabetic patients above 50 was 11.21 times as much as those below 50 years of age (odds ratio (OR): 11.21, 95% confidence interval (CI): 6.40-19.62).Conclusion:Concerning the high prevalence rate of ED in men suffering from type II diabetes, doctors are required to directly ask them about sexual disorders in follow-up visits. Furthermore, using screening questionnaires can be helpful in identifying this problem.

Major advantages include no de novo erectile dysfunction and low rate of retrograde ejaculation. Discontinuation of peri-operative antiplatelet and/or anticoagulation (APAC) is often preferred in practice to avoid bleeding complications. The objective of this study is to examine outcomes and complications in patients undergoing Rezūm on APAC. METHODS: We retrospectively reviewed patients who underwent Rezūm therapy at our institution since 7/2017. When deemed medically necessary, APAC was continued in the perioperative setting. Post-procedure catheterization regimen included a minimum of 3 days and a maximum of 4 weeks in men with preoperative catheter dependence. Outcomes included pre- and post-operative AUA symptoms score, peak flow, and postvoid residual. Bleeding-related complications and urinary tract infection rate were recorded. RESULTS: Of 214 patients who underwent Rezūm therapy, 68 patients were treated on APAC. The average prostate gland size was 73 grams. Significant improvements were seen in AUA symptom score, peak flow, and post void residual (Table 1). Bleeding complications requiring intervention occurred in 6 (9.3%) patients, with all 6 undergoing catheter irrigation, 2 undergoing blood transfusion, and 1 undergoing cystoscopic clot evacuation. Interestingly, 9/146 (6.3%) patients who were not on APAC had hematuria requiring intervention. There were no statistically significant differences in bleeding complications. There was no de novo erectile dyfunction reported. CONCLUSIONS: In our experience, bleeding complications in patients undergoing Rezūm on APAC is uncommon. There were no apparent differences in complication rates between patients on APAC and those not on APAC. To the best of our knowledge, this is the largest study to examine outcomes and complications of Rezūm in patients on APAC. Rezūm appears to be a safe and efficacious treatment option in men continuing APAC who wish to preserve sexual function.

Is Holmium Laser Enucleation of the Prostate a Good Surgical Alternative in Benign Prostatic Hyperplasia Management? A Review Article.

Several therapeutic approaches such as holmium laser enucleation of the prostate (HoLEP) have been introduced to relieve bladder outlet obstruction caused by benign prostatic hyperplasia (BPH). Compared with other techniques including the transurethral resection of the prostate (TURP) and simple open prostatectomy, HoLEP results in a shorter hospital stay and catheterization time and fewer blood loss and transfusions. HoLEP is a size-independent treatment option for BPH with average gland size from 36 g to 170 g. HoLEP is a safe procedure in patients receiving an anticoagulant and has no significant influence on the hemoglobin level. Also, HoLEP is an easy and safe technique in patients with a prior history of prostate surgery and a need for retreatment because of adenoma regrowth. The postoperative erectile dysfunction rate of patients treated with HoLEP is similar to TURP or open prostatectomy and about 77% of these patients experience loss of ejaculation. Patients with transitional zone volume less than 30 mL may suffer from persistent stress urinary incontinence following HoLEP so other surgical techniques like bipolar TURP are a good choice for these patients. In young patients, considering HoLEP with high prostate-specific antigen density and a negative standard template prostate biopsy, multiparametric MRI needs to be considered to exclude prostate cancer.

Phosphodiesterase Type-5 Inhibitor Prescription Patterns in the United States Among Men With Erectile Dysfunction: An Update

BackgroundWhile phosphodiesterase type-5 inhibitors (PDE5Is) are highly effective for the treatment of erectile dysfunction (ED) and well tolerated, updated data on prescription patterns have been limited in real-world settings. AimTo describe men in the United States who are prescribed PDE5Is for ED treatment and to evaluate patterns of initiation, switching, and treatment overlap. MethodsThis retrospective claims study used MarketScan Commercial and Medicare Supplement Databases from January 1, 2010, to December 31, 2015, to identify initial PDE5I claims (index date) for sildenafil, tadalafil, and/or vardenafil. Adults aged ≥18 years with ED were identified between July 1, 2010, and December 31, 2014, allowing for a 6-month preindex and 12-month follow-up period from the index date. OutcomesOutcomes included patient demographics and treatment-related patterns after treatment initiation. ResultsA total of 106,206 identified patients met all inclusion criteria. Of these, 51,694, 40,193, and 14,319 had initial claims for sildenafil, tadalafil, and vardenafil, respectively. Mean age was 50.35 years, and comorbidities included dyslipidemia (44.17%), hypertension (43.09%), diabetes (15.32%), and depression (10.61%). More patients (48.67%) initiated on sildenafil than tadalafil (37.85%) or vardenafil (13.48%). Rate of switching was lower in the 60 days after the end of day supply of the initial prescription in the sildenafil cohort (2.71%) compared with the tadalafil (2.81%) and vardenafil (3.88%) cohorts (P < .001 for sildenafil vs tadalafil or vardenafil). Treatment overlap was lower in the sildenafil cohort (0.35%) than in the tadalafil (0.75%) and vardenafil (0.62%) groups (P < .001 for sildenafil vs tadalafil or vardenafil). Clinical ImplicationsThese findings provide insight into updated patterns of PDE5I prescriptions in the United States and may aid in clinical decision-making. Strengths & LimitationsStrengths include the large sample size, long data coverage period, and the real-world nature of the study. Limitations include the retrospective study design, use of data collected with a primary focus of claims, and lack of further details regarding reasons that drive switching. Actual rates of ED and impact on prescription patterns may be underestimated because the claims database only captured patients electing to visit a health-care provider. ConclusionAmong men with ED in the United States, rates of switching and treatment overlap were low for all PDE5Is but were found to be the lowest for sildenafil compared with tadalafil and vardenafil.Mulhall JP, Chopra I, Patel D, et al.

Evaluation of functional outcomes after a second focal high-intensity focused ultrasonography (HIFU) procedure in men with primary localized, non-metastatic prostate cancer: results from the HIFU Evaluation and Assessment of Treatment (HEAT) registry.

To assess change in functional outcomes after a second focal high-intensity focused ultrasonography (HIFU) treatment compared with outcomes after one focal HIFU treatment. In this multicentre study (2005-2016), 821 men underwent focal HIFU for localized non-metastatic prostate cancer. The patient-reported outcome measures of International Prostate Symptom Score (IPSS), pad usage and erectile function (EF) score were prospectively collected for up to 3years. To be included in the study, completion of at least one follow-up questionnaire was required. The primary outcome was comparison of change in functional outcomes between baseline and follow-up after one focal HIFU procedure vs after a second focal HIFU procedure, using IPSS, Expanded Prostate Cancer Index Composite (EPIC) and International Index of Erectile Function (IIEF) questionnaires. Of 821 men, 654 underwent one focal HIFU procedure and 167 underwent a second focal HIFU procedure. A total of 355 (54.3%) men undergoing one focal HIFU procedure and 65 (38.9%) with a second focal HIFU procedure returned follow-up questionnaires, respectively. The mean age and prostate-specific antigen level were 66.4 and 65.6years, and 7.9 and 8.4ng/mL, respectively. After one focal HIFU treatment, the mean change in IPSS was -0.03 (P = 0.02) and in IIEF (EF score) it was -0.4 (P = 0.02) at 1-2years, with no subsequent decline. Absolute rates of erectile dysfunction increased from 9.9% to 20.8% (P = 0.08), leak-free continence decreased from 77.9% to 72.8% (P = 0.06) and pad-free continence from 98.6% to 94.8% (P = 0.07) at 1-2years, respectively. IPSS prior to second focal HIFU treatment compared to baseline IPSS prior to first focal HIFU treatment was lower by -1.3 (P = 0.02), but mean IPSS change was +1.4 at 1-2years (P = 0.03) and +1.2 at 2-3years (P = 0.003) after the second focal HIFU treatment. The mean change in EF score after the second focal HIFU treatment was -0.2 at 1-2years (P = 0.60) and -0.5 at 2-3years (P = 0.10), with 17.8% and 6.2% of men with new erectile dysfunction. The rate of new pad use was 1.8% at 1-2years and 2.6% at 2-3years. A second focal HIFU procedure causes minor detrimental effects on urinary function and EF. These data can be used to counsel patients with non-metastatic prostate cancer prior to considering HIFU therapy.

Erectile dysfunction after surgery for rectal cancer: a prospective study.

Erectile dysfunction may occur as a complication of surgical treatment of rectal cancer in male patients. We compared the rates of postoperative erectile dysfunction and response to medical treatment after low anterior resection (LAR) and Miles' procedures. Fifty patients who underwent the Miles' procedure or LAR were prospectively assessed. This study includes fifty patients with stages 1 and stage 2 rectal cancer based on clinical and radiologic assessments, who underwent Miles' (25 out of 50 patients underwent the Miles'procedure and ) or LAR (25 patients underwent LAR) procedures were prospectively assessed. The International Index of Erectile Function (IIEF) form was, used in the assessment to assess erectile dysfunction. This questionnaire, was administered preoperatively and 6 months postoperatively. For the patients with IIEF scores ≤ 25 at postoperative 6th months, tadalafil 5 mg is was given for 12 weeks and IIEF is was repeated after then. No significant differences were found in mean IIEF scores preoperatively (p= 0.695). In both groups, IIEF scores were significantly lower postoperatively compared with preoperatively (p= 0.00001, LAR; p= 0.00001, Miles'). Mean postoperative IIEF scores were significantly lower in patients who underwent Miles' compared with the LAR procedures (p= 0.0001). For patients with IIEF scores ≤ 25 at 6 months, tadalafil 5 mg was given for 12 weeks and IIEF scores were better in both groups (p= 0.00001). The erectile dysfunction rate after Miles' procedure was significantly higher than the rate of patients who developed erectile dysfunction after LAR surgery. We tried to emphasize that in after LAR surgery. We should not be concerned only with cancer treatment surgically in rectal tumour patients, but remember that situations affecting their social life, such as postoperative erectile dysfunction, have medical and psychologic importance.

Interventional therapy in malignant conditions of the prostate.

Interventional therapies are emerging modalities for the treatment of localized prostate cancer. Their aim is to reduce the morbidity associated with radical therapies (rT) by minimizing damage to non-cancerous tissue, with priority given to sparing key structures such as the neurovascular bundles, external sphincter, bladder neck, and rectum, while maintaining local cancer control. Interventional ablative technologies deliver energy in different ways to destroy cancer cells. The most widely investigated techniques are brachytherapy, external beam radiotherapy, cryotherapy, and high-intensity focused ultrasound. Although functional outcomes of focal therapies have been encouraging, with generally low rates of urinary incontinence and erectile dysfunction, robust medium- and long-term oncological outcomes are not available for all techniques. To date, major controversies in focal therapy concern appropriate patient selection, efficacy of focal therapies, as well as treatment paradigms based on the dominant index lesion hypothesis. This review articles discusses the current status of interventional therapies and the oncological and functional outcomes.

A Systematic Literature Review of the Burden of Ischemic Priapism in Patients with Sickle Cell Disease

INTRODUCTION: Ischemic or low-flow priapism is a serious condition characterized by a persistent, painful erection that lasts at least 4 hours or is unrelated to sexual stimulation. Both stuttering (repeated short episodes) and fulminant (long-lasting) priapism are prevalent in men and boys with sickle cell disease (SCD). Approximately 40% of patients with SCD will experience priapism during their lifetime. The objective of this study was to conduct a systematic literature review (SLR) to identify published studies reporting the burden associated with priapism in patients with SCD. METHODS: MEDLINE, Embase, Cochrane CENTRAL/CDSR and 14 congresses were searched from May 9-16, 2019. Results were screened against predefined criteria by two independent researchers. Studies assessing the clinical, humanistic, or economic burden of human patients with SCD and priapism (N≥15) were included. Outcomes of interest included priapism-related symptoms, treatment-related complications, quality of life (QoL), and economic burden. RESULTS: The literature search identified 1236 articles; 62 full-text studies were reviewed in detail and 34 studies were included in the analysis. Most studies were retrospective observational (21), others were prospective (7 observational, 6 interventional). Study size varied widely (range: 15-10,788 patients). Of 27 studies that reported mean or median patient age, the age statistic for patients with SCD and priapism ranged from 10 to 32. Overall, 19 studies reported at least one aspect of clinical burden. Thirteen reported the rate of erectile dysfunction or impotence, ranging from 0% to 56%. Eight reported treatment-related complications, including perceived penile scarring/deformity (19.4%) and small intrapenile hematoma (13.3%). Nineteen studies reported QoL outcomes. Eight reported physical outcomes, including a negative impact of SCD-related priapism on sleep quality and worse scores on periodic limb movement and apnea hypopnea indices. Seven reported measures of sexual function, including low rates of satisfactory sexual intercourse. One study reported a diminished Sexual Health Inventory for Men score in patients with active priapism, and another found a statistically significant relationship between stuttering priapism and premature ejaculation. Three studies reported measures of mental function, one of which outlined increased cognitive fatigue and impaired emotional functioning among children with priapism and another reported that 36% of patients had substantial to very extreme worry regarding episodes of priapism. Use of validated measures for QoL were limited: 3 studies assessed patients with the International Index of Erectile Function (IIEF) and 1 with the Priapism Impact Profile (PIP). No studies measuring the burden to caregivers of pediatric patients with priapism were identified. Eight studies reported the economic burden of priapism in patients with SCD, including rates of emergency department visits (4 studies: 56.5% sought hospital treatment - 26/46; 49.8% admission to the hospital out of emergency department visits - 5371/10,788; 50.4% admitted at the emergency department - 930/1844; 26% vs. 11% readmission vs no readmission - p &amp;lt;0.001) and hospital length of stay (4 studies: mean 3.38 days; mean 3.8 days; median 2 days; median 5 days in patients who received an exchange transfusion as a treatment for priapism.). Three studies reported direct treatment costs, ranging from a mean of $4496 (2015 USD) for patients who did not undergo penile operations to a mean of $19,670 (2013 USD) total adjusted hospital costs for patients receiving both transfusions and urologic procedures. CONCLUSIONS: This SLR identified 34 studies reporting the burden of priapism in patients with SCD. No RCTs were identified. The use of comprehensive or validated measures of humanistic burden was limited. Manifestations of priapism are wide-ranging, including painful treatment-related complications, impaired sleep, and diminished physical, mental and sexual function. Patients with priapism and SCD are more likely to visit the emergency department and experience longer hospital stays compared to SCD patients without priapism. Together, the evidence identified in this SLR indicates that priapism not only can result in erectile dysfunction, but can impair multiple dimensions of a patient's physical and mental health.

Outcomes Following Primary Realignment Versus Suprapubic Cystostomy with Delayed Urethroplasty for Pelvic Fracture-Associated Posterior Urethral Injury: A Systematic Review with Meta-Analysis

Objective: Pelvic fracture can be complicated by posterior urethral injury (PUI) in up to 25% of cases. PUI can produce considerable morbidity, including urethral stricture, erectile dysfunction (ED), and urinary incontinence. Optimal management of PUI is unclear, however, the current gold standard is placement of a suprapubic cystostomy with delayed urethroplasty (SCDU) performed several months later. Another option is early primary realignment (PR) with urethral catheter, performed either open or endoscopically. Through a systematic review and meta-analysis, we aimed to compare PR and SCDU regarding stricture, ED, and urinary incontinence rates. In light of advancing endoscopic techniques, we also aimed to compare early endoscopic realignment (EER) alone with SCDU. Methods: PubMed, Medline, and Embase were searched for eligible studies comparing PR, including EER, and suprapubic cystostomy plus delayed urethroplasty from database inception until July 17th, 2018. We also reviewed reference lists from relevant articles. Study quality assessment was conducted using a modified Newcastle-Ottawa (mNOS) scale (maximum score 9). Results: From 461 identified articles, 13 studies encompassing 414 PR and 308 SCDU patients met our eligibility criteria. Twelve studies were retrospective non-randomized case studies, with 1 prospective randomized case study. Included studies were of moderately low quality (mNOS mean score: 6.0 ± 0.6). Meta-analysis demonstrated that PR and SCDU had similar stricture rates [odds ratio (OR): 2.14; 95% confidence interval (CI): 0.67-6.85; p = 0.20], similar rates of ED (OR: 1.06; 95% CI: 0.62-1.81; p = 0.84), and similar rates of urinary incontinence (OR: 0.94; 95% CI: 0.49-1.79; p = 0.86). Six studies compared EER alone (229 patients) versus SCDU (195 patients). Meta-analysis demonstrated that these modalities also had similar stricture rates (OR: 4.14; 95% CI: 0.76-22.45; p = 0.10), similar rates of ED (OR: 0.79; 95% CI: 0.41-1.54; p = 0.49), and similar rates of urinary incontinence (OR: 1.10; 95% CI: 0.48-2.53; p = 0.82). Conclusion: For PUI patients, neither PR nor EER produces superior outcomes compared to SCDU regarding stricture, ED, and urinary incontinence rates. The quality of studies in the literature, however, is very poor, with the majority of studies being non-randomized retrospective case studies with potentially high bias. Additional high-quality research, particularly prospective studies and randomized controlled trials, are needed to strengthen the evidence base.

1832P - Erectile dysfunction in patients with metastatic renal cell carcinoma

BackgroundMetastatic renal cell carcinoma (mRCC) can cause sexual dysfunction as an adverse effect in male patients. Erectile dysfunction (ED) can also result from adverse effects of targeted therapy of mRCC, such as fatigue, pain, anorexia, asthenia or hypothyroidism. The objective of the study was to evaluate the rate of ED in a male population with mRCC. MethodsOne hundred thirty-two male patients with clear cell mRCC were enrolled. All patients were evaluated for erectile function with the 5-item version of the International Index of Erectile Function (IIEF-5) before and after the first cycle/month of the first-line targeted therapy with sunitinib, pazopanib, bevacizumab+IFN, sorafenib, or temsirolimus. ResultsMedian age was 59 years (range 43–67 years). 89 (67%) patients had at least one cardiovascular risk factor. At baseline, IIEF-5 mean score was 19 (SD, 2.6). Patients with 2 and more IMDC risk factors (39%) had a lower IIEF-5 mean score (14; SD, 3.3). 99 (75%) patients reported a negative change in their sexual life since the start of the targeted therapy. 35 (27%) patients had no sexual activity. After the first treatment cycle/month IIEF-5 mean score reduced to 8 (SD, 1.9), which was statistically significant (P<0.001). The IIEF-5 scores were not associated with a type of anticancer treatment (P>0.05). ConclusionsProspective evaluation in a large cohort of patients with mRCC revealed mild ED (19/25) in the treatment-naive male population and severe ED (8/25) after the first cycle/month of the first-line targeted therapy. Significant decrease in erectile function should be considered as a potential adverse event in male patients undergoing treatment of mRCC with targeted agents.

The Comorbidity Between Premature Ejaculation and Erectile Dysfunction—A Cross-Sectional Internet Survey

IntroductionThe comorbidity between premature ejaculation (PE) and erectile dysfunction (ED) has not yet been clarified.AimTo assess the comorbidity between PE and ED.MethodsMale members of a shopping club in Taiwan aged 20–60 years with stable sexual relationships were invited to complete an online questionnaire.Main Outcome MeasuresSelf-estimated intravaginal ejaculatory latency time (IELT), Premature Ejaculation Diagnostic Tool, Sexual Health Inventory for Men, Self-Esteem and Relationship, and Hospital Anxiety and Depression Scale results were used.ResultsA total of 937 participants with a mean age of 41.1 ± 10.2 years were enrolled. The prevalence rates of ED (Sexual Health Inventory for Men ≤ 21), PE (Premature Ejaculation Diagnostic Tool ≥11), and IELT ≤1 minute were 24.7%, 6.3%, and 6.4%, respectively. Prevalence of acquired PE and IELT ≤1 minute increased marginally with age. Participants with ED had a greater prevalence of PE than those without ED (19.5% vs 2.0%, P < .001), and participants with PE had a greater prevalence of ED than those without PE (76.3% vs 19.4%, P < .001). Compared with participants without PE, participants with PE had greater adjusted odds of ED (odds ratio [OR] = 12.7, 95% CI = 6.7–24.2). Relative to participants without ED, participants with ED had increased adjusted odds of PE (OR = 7.2, 95% CI = 3.5–14.6 with mild ED and OR = 36.7, 95% CI = 16.2–83.0 with ED severity greater than a mild degree). Poor sexual relationships and self-esteem, depression, and anxiety were reported more frequently in those with PE or ED, especially in those with both problems compared with those without PE and ED.ConclusionsThis study confirmed a high prevalence of PE and ED coexistence, indicating a complicated relationship between the 2 conditions and the importance of screening for their co-occurrence in practice.Tsai W-K, Chiang P-K, Lu C-C, et al.

Advantages and Disadvantages of Methadone among Children and Adults: A Systematic Review and Meta-Analysis

Background: Today, an increasing trend to methadone as an alternative maintenance treatment for opiate dependence in adults is observed; children for both intentional and accidental reasons are exposed to serious and fetal effects of methadone. We aimed to investigate effects of methadone on children and sexual functioning among adults in Iranian population. Materials and Methods: An extensive search was done in databases of Medline, EMBASE, Scopus, Cochrane, and Web of Science until August 2018. Two independent researchers screened articles, and categorized them based on the evaluated outcomes and overall effect size was presented. After excluding the duplicated, irrelevant and low-quality articles, eligible ones were enrolled in the meta-analysis. Finally, pooled effect size was presented as standardized mean difference (SMD) or pooled prevalence with 95% confidence interval (95% CI). Results: Methadone was found to be more effective than morphine on neonatal abstinence syndrome. The first four most common symptoms of methadone poisoning were loss of consciousness (81%), sleepiness (72%), meiotic pupils (76%), vomiting (56%), and Apnea (48%). The overall prevalence rate of sexual disorders and erectile dysfunction was 66.3% and 77.5%, respectively. The subjects in methadone group were over 2.5-fold more likely to use condom during intercourse (p<0.001). The methadone therapy could lead to a significant reduction in orgasm functioning (p<0.001), and a significant improvement in libido (p=0.001). The methadone maintenance treatment (MMT) significantly resulted in decreased orgasm function and improved libido in males. Conclusion: Evidence suggests a positive impact of methadone maintenance treatment on risky sexual behaviors. Regarding the methadone poisoning effect on children, people should be informed by health care providers about serious and fetal effects on children.

Epidemiology Update of Erectile Dysfunction in Eight Countries with High Burden.

Prior epidemiology studies on erectile dysfunction (ED) have varied in geography/place, time period, and methodology. Due to this variability, comparisons of data across studies are greatly limited. Additionally, little is known about the rates of comorbid ED and benign prostatic hyperplasia (BPH). To update the prevalence of ED and patient characteristics using a single methodology in 8 countries: Brazil, China, France, Germany, Italy, Spain, the United Kingdom, and the United States. This retrospective cross-sectional study included men (≥18 years) who self-reported experiencing difficulty in achieving or maintaing an erection in the past 6 months in the 2015 and 2016 National Health and Wellness Surveys (N= 97,159). Pairwise comparisons between the United States and each of the other countries were performed among respondents with ED and no BPH, aged ≥18 years, and within the subset of men aged 40-70 years. ED prevalence (with BPH, with no BPH, and overall), health characteristics, and ED risk factors were assessed. ED with BPH was found to be < 6.0% in all countries. ED prevalence overall varied from 37.2% (Brazil) to 48.6% (Italy). Similar patterns were observed for the subset of men aged 40-70 years. Patients in Brazil were younger (aged ≥18: 43.85 vs. 52.35; aged 40-70: 52.94 vs. 56.76 years; for both, P < .05) than those in the United States. ED-related comorbidities were more common in European countries, comparatively. This study provides an important update and outlook to ED epidemiology in Brazil, China, France, Germany, Italy, Spain, the United Kingdom, and the United States. Overall, ED prevalence is high, relative to some previous estimates. Findings from this study highlight the continued burden ED plays in the lives of men in these countries.

Comparative Cost-effectiveness of Surgery, Collagenase Clostridium Histolyticum, and Penile Traction Therapy in Men with Peyronie’s Disease in an Era of Effective Clinical Treatment

BackgroundTraditionally, surgery has been considered the gold standard treatment for Peyronie’s disease (PD). Less-invasive alternatives, such as collagenase Clostridium histolyticum (CCH) and traction therapy, have been proposed and proven effective. AimTo compare cost-effectiveness of management options for PD. MethodsA Markov analytic model was created to compare the cost-effectiveness of treatment with a novel traction device, RestoreX (RXPTT), vs CCH vs surgery. Outcomes were derived from single-institution, prospective data of 63 men treated with RXPTT, 115 with CCH, and 23 with plication or incision and grafting. Costs were based on 2017 Medicare reimbursement and utility values from the literature. Main Outcome MeasuresModel outcomes included complications for each treatment arm, as well as the probability of success, which was defined as ≥20% improvement in curvature. Univariable and multivariable sensitivity analyses were performed to test the robustness of the model. ResultsOverall success rates were 96% (surgery), 66% (CCH), and 48% (RXPTT). At 10 years after treatment, RXPTT was the most cost-effective, with mean costs per patient of $883 (RXPTT), $11,419 (surgery), and $33,628 (CCH). CCH and surgery both resulted in a gain of quality adjusted life years (QALYs) relative to RXPTT (9.44 and 9.36 vs 9.27, respectively). Sensitivity analysis demonstrated greater cost-effectiveness for surgery if lower (≤46%) rates of postoperative erectile dysfunction or length loss (≤3%). CCH became more cost-effective at lower costs (≤$16,726) or higher success rates (≥76%). On multivariable sensitivity analysis at a willingness to pay threshold of $100,000/QALY, the most cost-effective strategy was RXPTT in 49%, surgery in 48%, and CCH in 3% of simulations. At a willingness to treat threshold of $150,000/QALY, the most cost-effective treatment option was RXPTT in 33%, surgery in 55%, and CCH in 12% of simulations. Clinical ImplicationsIn an era of value-based care, this model can guide cost-effective treatment selection on the basis of provider, patient, and payer characteristics. Strengths & LimitationsThe current study represents the first cost-effectiveness comparison of treatment modalities for PD and is strengthened by prospective data collection, large CCH and traction sample sizes, and robust sensitivity analyses. Consistent with cost-effective models, the model is limited by assumptions and may not apply to all scenarios. ConclusionsRXPTT represents a more cost-effective method for achieving ≥20% curvature improvement compared with surgery or CCH. Depending on treatment goals, rate of surgical complications, and willingness to pay threshold, surgery and CCH may become more cost-effective in select scenarios.Wymer K, Kohler T, Trost L.

Prevalence of Erectile Dysfunction and Awareness of Its Treatment in Abuja, Nigeria

Introduction: Erectile dysfunction (ED) is the most common male sexual dysfunction all over the World. It is underestimated in developing countries including Nigeria because it is assumed not to be a life threatening condition which is associated with stigmatization and poor health seeking behavior. The Prevalence rate of ED among specific age groups has not been reported in most available local studies. This study was aimed at determining the prevalence rates of ED and the severity of ED among different age groups and patients’ awareness of its treatment.&#x0D; Methods: The study was a descriptive cross-sectional hospital based survey among men aged 18 years and above seen in the outpatient clinics of University of Abuja Teaching Hospital, Gwagwalada, Abuja, Nigeria. Self reported erectile dysfunction was obtained using proforma. The prevalence and severity of ED was obtained using International Index of Erectile Function-5 Questionnaire (IIEF-5).&#x0D; Results: A total of 378 subjects were recruited for this study with age range of 18-76 years. The prevalence of ED in this study using IIEF-5 was 66.4%. The prevalence of ED was noted to increase with increasing age as ED was more prevalent (59%) among men aged 60-79 year. ED was least common among the young subjects (15.7%) and the most severe ED found among the elderly There was a positive correlation between age and ED (rho =0.306). There was statistically significance association between ED and co-morbidities with hypertension accounting for 22.5% and diabetes 16.7%. The percentage of subjects aware of treatment for ED was 39.4% and 20.4% of the subjects had sought help from doctors. Only about a quarter (26.5%) of the subjects had their sexual challenges discussed with the doctor.&#x0D; Conclusion: ED is a common medical and social problem in our environment though still shrouded in secrecy. ED is more prevalent and severe among age 60-79 years. Awareness of treatment seeking behavior and the ability of the attending physicians to discuss with men about their sexual health remains quite poor in our environment.
