Meta-Analysis Review
Little is known about the ongoing monkeypox (mpox) outbreak, and the clinical features of mpox in patients worldwide have not been rigorously analysed. Thus, we aimed to investigate the clinical features associated with mpox infection and understand the pathophysiology and characteristics of the disease. For this systematic review and meta-analysis, we searched PubMed/MEDLINE, Embase, CINAHL, Google Scholar, and the Cochrane Database of Systematic Reviews for articles published till 16 September 2022. We used a random effects model to calculate the pooled prevalence and 95% confidence interval (CI). We used the I statistic to assess heterogeneity, Egger's test to assess publication bias, 95% prediction interval to determine the level of uncertainty, and the Newcastle-Ottawa Scale and Joanna Briggs Institute quality assessment tool to assess the risk of bias. Twenty-six relevant articles from 19 countries across 5 continents were included, and data on 5472 mpox patients with 18 unique features were analysed. The pooled prevalence of clinical features of mpox were rash (85.7%, 95% CI: 68.3-94.3; k = 21), chills (77.8%, 95% CI: 70.5-83.7; k = 3), and fever (62.3%, 95% CI: 51.3-71.6; k = 25), lymphadenopathy (58.6%, 95% CI: 47.2-69.2; k = 21), lethargy or exhaustion (46.8%, 95% CI: 30.7-63.5; k = 14), pruritus (40.6%, 95% CI: 28.5-54.0; k = 5), myalgia (36.0%, 95% CI: 24.3-49.7; k = 16), headache (34.6%, 95% CI: 23.4-47.8; k = 17), skin ulcer (31.1%, 95% CI: 18.6-47.1; k = 7), abdomen symptom (24.2%, 95% CI: 17.9-31.9; k = 11), pharyngitis (23.0%, 95% CI: 12.7-37.9; k = 14), respiratory symptom (19.5%, 95% CI: 6.8-44.6; k = 6), nausea or vomiting (13.0%, 95% CI: 4.6-31.9; k = 3), scrotal or penile oedema (10.7%, 95% CI: 6.3-17.7; k = 4), conjunctivitis (7.1%, 95% CI: 2.4-18.9; k = 6), and death (0.9%, 95% CI: 0.4-2.0; k = 26). This is the first international and comprehensive study to examine all clinical presentations of human mpox infection. Our systematic review proposes a comprehensive understanding of the current mpox outbreak and may serve as key data for future studies on the pathological mechanisms and epidemiology of mpox infections.

Review
INTRODUCTION
Stem cells for sexual disorders are steadily being introduced into clinical trials. Two conditions of importance are the main target for this line of treatment, especially when regarding the wide array of translational and basic science highlighting the potential advantages of regenerative therapy: erectile dysfunction (ED) and more recently Peyronie disease (PD). Cellular therapy offers a treatment modality that might reverse disease progression. It would be used in a curative setting, in contrast to other pharmaceutical agents that are currently available.
AIM
To review basic preclinical studies and recent clinical trials of stem cells on ED and PD.
METHODS
A search of the medical literature for the following terms was performed using PubMed: stem cells, cellular therapy, erectile dysfunction, Peyronie's disease, and clinical trial.
MAIN OUTCOME MEASURES
A non-systematic narrative review and critical reflection on preclinical and clinical studies administering stem cells for ED and PD in animal models and human subjects.
RESULTS
Numerous studies have confirmed the beneficial functional effects of stem cell injection in established animal models on ED and PD. Various stem cell types have been adopted, from embryonic to adult mesenchymal cell types. Each cell type offers distinctive advantages and disadvantages. Diverse administrations of stem cells were investigated, with insignificant variability in the ultimate results. Stem cells appear to have a pronounced paracrine effect, rather than the classic engraftment and differentiation hypothesis. Phase 1 clinical trials using stem cells have not reported any severe adverse events in animals. However, these results cannot be extrapolated to draw any conclusions about efficacy in human patients.
CONCLUSION
Stem cells have an established efficacy in preclinical studies and early clinical trials. Studies are currently being published demonstrating the safety of intrapenile injection of autologous bone marrow- and adipose tissue-derived stem cells. Soebadi MA, Milenkovic U, Weyne E, et al.

Review
OBJECTIVE
To review recent literature pertaining to collagenase clostridium histolyticum (CCh)and other intralesional (IL) therapies for the treatment of Peyronie's disease (PD).
METHODS
A systematic search of literature was performed using MEDLINE and PubMed.'Peyronie's Disease Clostridium Histolyticum', 'Peyronie's Disease Intralesional', 'Peyronie'sDisease Causes', and 'Atypical Peyronie's Disease' were used as query entries. Inclusion criteriarequired English text from 1980 onwards and have a full text available. Records were reviewed for study power, accuracy, and relevance to our research topic. The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria.
RESULTS
Recent literature supports the notion that CCh is the most effective IL treatment forpatients with typical and atypical PD. The capstone CCh study was the IMPRESS trial thatshowed a 34% reduction in curvature with a mean (SD) - 17.0 (14.8)° reduction with IL CCh,while men in the placebo saw an average 18.2% decrease in penile bend with a mean (SD) - 9.3 (13.6)° per person (P < 0.001). A shortened protocol for IL CCh treatment offered a 31.4%reduction in curvature, while decreasing cost and office visits, potentially increasing patientcompliance. Lastly, literature shows CCh is used most in atypical cases, with ~64.8% of patients being treated with CCh, probably because of the high efficacy and safetyprofile that it offers. Serious complications associated with CCh include urethralinjury, corporal rupture, and penile fracture.
CONCLUSION
Since the approval of CCh by the United States Food and Drug Administration in2013, it has been a staple in the treatment of PD, and here we report the continuedsuperiority of this therapy. CCh is an effective, minimally invasive option in most PDpopulations; however, recent changes have made CCh unavailable for commercial use outside the United States, impacting many patients who have previously benefited.

Journal of Lower Genital Tract Disease Jul 2019The aim of the study was to review uncommon foreskin dermatopathology conditions clinically and pathologically.
OBJECTIVES
The aim of the study was to review uncommon foreskin dermatopathology conditions clinically and pathologically.
METHODS
A database search of PubMed and Google Scholar were extracted between March 1, 2009, and March 1, 2019, using the search terms "foreskin," "prepuce," "penis," "pathology," "dermatology," and "rare." The search was limited to "humans" and "dermatopathology." Full article texts were reviewed. Reference lists were screened for additional articles. Patient details (diagnosis, dermatopathology, treatment, and follow-up if available) were extracted. We excluded articles written in the non-English language, unusual variants of common conditions, and cases of common dermatologic conditions.
RESULTS
A list of 369 articles was identified and another screening identified 30 articles for rare foreskin pathologies. Those are divided into categories based on the following etiologies: (a) benign, including congenital (e.g., aposthia), infectious (graft versus host disease and histoplasma), autoimmune (Crohn's disease and pyoderma gangrenosum), and benign neoplasms (neurofibroma, apocrine hidrocystoma, verruciform xanthoma, porokeratosis, penile cutaneous horn, localized amyloidosis) and (b) malignancies, including primary (myeloid sarcoma, basal cell carcinoma, Kaposi's sarcoma, mucosal-associated lymphoid tissue lymphoma), and metastasis.
CONCLUSIONS
We reviewed and discussed unusual benign and malignant dermatopathology conditions that can affect the foreskin.

BACKGROUND AND AIMS
Metastatic Crohn's disease is an extraintestinal cutaneous manifestation characterised by non-specific inflammatory lesions anatomically separate from the gut; genital involvement is rare. We conducted a systematic review of anogenital Crohn's disease and granulomatosis, to provide a synthesis of epidemiology, clinical features, and treatment outcomes.
METHODS
A systematic search of the literature was conducted via MEDLINE, EMBASE, and the Cochrane database from inception to December 1, 2020. Two investigators extracted and analysed study data. Response and remission were defined as partial improvement or complete resolution of symptoms and examination findings, respectively.
RESULTS
Of 9381 screened studies, 185 articles, [410 cases: 273 female, 137 male] were included. The predominant clinical features were oedema, ulcers, fissures, and hypertrophic lesions. Adults and children present similarly. Luminal Crohn's disease was diagnosed in nearly 80% of cases including 45-80% patients without gastrointestinal symptoms (time to inflammatory bowel disease [IBD] from anogenital Crohn's disease diagnosis [range] -43 to 11 years). Antibiotics, corticosteroids, thiopurines, and anti-tumour necrosis factor [TNF] therapy were the most frequently prescribed agents. At final follow-up, non-response, response, and remission rates were 37/304 [12%], 267/304 [88%], and 114/304 [38%], respectively. Oedema was associated with a poor response to topical therapy. Greater response rates to anti-TNF therapy were seen in patients prescribed concomitant immunomodulation [24/25, 96% vs 67/90, 74%, p = 0.02].
CONCLUSIONS
We provide an illustrative summary of the clinical presentation and treatment effectiveness of this rare, under-recognised condition, and a proposed algorithm for approach and management. Prospective studies with longer follow-up are required to define optimal treatment strategies.

CONTEXT
Lymph node (LN) involvement in penile cancer is associated with poor survival. Early diagnosis and management significantly impact survival, with multimodal treatment approaches often considered in advanced disease.
OBJECTIVE
To assess the clinical effectiveness of treatment options available for the management of inguinal and pelvic lymphadenopathy in men with penile cancer.
EVIDENCE ACQUISITION
EMBASE, MEDLINE, the Cochrane Database of Systematic Reviews, and other databases were searched from 1990 to July 2022. Randomised controlled trials (RCTs), nonrandomised comparative studies (NRCSs), and case series (CSs) were included.
EVIDENCE SYNTHESIS
We identified 107 studies, involving 9582 patients from two RCTs, 28 NRCSs, and 77 CSs. The quality of evidence is considered poor. Surgery is the mainstay of LN disease management, with early inguinal LN dissection (ILND) associated with better outcomes. Videoendoscopic ILND may offer comparable survival outcomes to open ILND with lower wound-related morbidity. Ipsilateral pelvic LN dissection (PLND) in N2-3 cases improves overall survival in comparison to no pelvic surgery. Neoadjuvant chemotherapy in N2-3 disease showed a pathological complete response rate of 13% and an objective response rate of 51%. Adjuvant radiotherapy may benefit pN2-3 but not pN1 disease. Adjuvant chemoradiotherapy may provide a small survival benefit in N3 disease. Adjuvant radiotherapy and chemotherapy improve outcomes after PLND for pelvic LN metastases.
CONCLUSIONS
Early LND improves survival in nodal disease in penile cancer. Multimodal treatments may provide additional benefit in pN2-3 cases; however, data are limited. Therefore, individualised management of patients with nodal disease should be discussed in a multidisciplinary team setting.
PATIENT SUMMARY
Spread of penile cancer to the lymph nodes is best managed with surgery, which improves survival and has curative potential. Supplementary treatment, including the use of chemotherapy and/or radiotherapy, may further improve survival in advanced disease. Patients with penile cancer with lymph node involvement should be treated by a multidisciplinary team.

Meta-Analysis Review
BACKGROUND
Human papillomavirus associated anogenital cancers are a significant global burden. The detection of biomarkers (circulating tumour DNA; ctDNA or circulating HPV DNA; cHPV DNA) in blood referred to as "liquid biopsy" may support the early diagnosis and monitoring of affected individuals.
METHODS
A systematic review, including meta-analysis of studies available in the literature on the utilization of ctDNA and cHPV DNA as diagnostic, predictive, and monitoring biomarker tests of HPV associated anogenital cancers was performed following the criteria of PRISMA.
RESULTS
A total of 31 studies were eligible for systematic review; 20 used cHPV DNA in cervical cancers; 7 used ctDNA in cervical cancer; 5 used cHPV DNA in anal cancer; no eligible studies on vulva, vaginal or penile cancer were available. The meta-analysis identified low sensitivity (0.36) and high specificity (0.96) of cHPV DNA as diagnostic for cervical cancer. Comparatively, there was high sensitivity (0.95) and specificity (1.0) of cHPV DNA for the diagnosis of anal cancer. cHPV DNA and/or ctDNA in cervical cancer were prognostic markers associated with poor clinical outcomes. Additionally, in anal cancer the post treatment detection of cHPV DNA was informative in the prediction of treatment response or progression-free survival.
CONCLUSION
ctDNA and cHPV DNA are promising diagnostic and prognostic biomarkers for the detection of anogenital disease. Evolution and refinement of molecular tools is likely to improve performance further. Additionally the comparative absence of studies in the vulval, vaginal and penile context warrants further exploration and research.

Review
BACKGROUND
In 2016, we reported the first case of high flow priapism and arteriocavernosal fistula caused by penile prosthesis insertion that mimicked device autoinflation.
AIM
To raise awareness amongst implanters, we describe further cases from our institution and perform a systematic review of the literature to understand the rarity of this phenomenon.
METHODS
Patient demographics, management and outcomes were extracted retrospectively. A systematic search of the EMBASE, PubMed and PubMed Central libraries for studies reporting arteriocavernosal fistula mimicking autoinflation since 1946 was performed.
OUTCOMES
To identify and report all known cases of high flow priapism and arteriocavernosal fistula presenting as autoinflation of an inflatable penile prosthesis.
RESULTS
Four patients in total (median age 56, range 46-60 years) were identified. Catastrophic bleeding (1.8L) occurred during revision surgery for presumed autoinflation in Patient 1 and subsequent ultrasound (US) confirmed a fistula which was embolized. Patient 2 redeveloped autoinflation following revision surgery. Ultrasound confirmed high flow priapism from an arteriocavernosal fistula. Patient 3 underwent penile magnetic resonance imaging (MRI) to investigate autoinflation and residual penile curvature. MRI showed a tumescent penis despite a deflated device and the fistula was embolized successfully. Patient 4 with sleep-related painful erections did not improve following insertion of penile prosthesis. Doppler US identified 2 fistulae that was embolized but with no resolution of symptoms. Subsequent embolization of both common penile arteries were done to control his symptoms. No other publications apart from the published abstract from 2016 reporting patient 1 was found.
CLINICAL IMPLICATIONS
If considered prior to revision surgery, the fistula can be managed safely by minimally invasive percutaneous angioembolisation avoiding surgery which can potentially be associated with significant complications.
STRENGTHS AND LIMITATIONS
The rarity of this phenomenon was supported by a systematic review. Our study however does present the findings from a small number of patients.
CONCLUSION
Damage to the cavernosal artery during inflatable penile prosthesis insertion can create an arteriocavernosal fistula that mimics autoinflation, leading to catastrophic intra-operative bleeding or unnecessary surgery.

Meta-Analysis
INTRODUCTION
Priapism is defined as a full or partial erection lasting longer than 4 hours after sexual stimulation and orgasm or unrelated to sexual stimulation. The main goal of priapism management is to resolve the episode immediately to preserve erectile function and penile length. Corporal smooth muscle necrosis is likely to have already occurred, and medically refractory erectile dysfunction is expected in patients with a protracted episode. Penile prosthesis implantation (PPI) in the early or late phase of priapism can restore erectile function.
AIM
To review the literature on PPI in priapism.
METHODS
A PubMed search of all English-language articles published before 2017 was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement using the following search terms: penile prosthesis implantation, priapism, and corporal fibrosis. All publications reporting on PPI during or after priapism episodes were included for review.
MAIN OUTCOME MEASURES
Three types of priapism were reviewed for management using PPI. Surgical techniques, outcomes, and patient satisfaction were reported.
RESULTS
Early implantation (during the episode) is technically easier and has lower complication rates compared with delayed (electively, after the erectile dysfunction is observed) surgery. Immediate PPI also allows preservation of penile length, which is related to higher satisfaction rates.
CONCLUSIONS
The paradigm is shifting toward immediate PPI in the management of ischemic priapism. Patients with non-ischemic priapism or recurrent priapism, even without a major ischemic episode, are at high risk for erectile dysfunction and are candidates for PPI. Yücel ÖB, Pazır Y, Kadıoğlu A.

Review
INTRODUCTION
Women's choices for a sexual partner are influenced by numerous personal, cultural, social, political and religious factors, and may also include aspects of penile anatomy such as male circumcision (MC) status.
AIM
To perform a systematic review examining (i) whether MC status influences women's preference for sexual activity and the reasons for this, and (ii) whether women prefer MC for their sons.
METHODS
PRISMA-compliant searches were conducted of PubMed, Google Scholar, Embase, and the Cochrane Database of Systematic Reviews. Articles that met the inclusion criteria were rated for quality using the SIGN system.
RESULTS
Database searches identified 29 publications with original data for inclusion, including 22 for aim (i) and 4 of these and 7 others pertaining to aim (ii). In the overwhelming majority of studies, women expressed a preference for the circumcised penis. The main reasons given for this preference were better appearance, better hygiene, reduced risk of infection, and enhanced sexual activity, including vaginal intercourse, manual stimulation, and fellatio. In studies that assessed mothers' preference for MC of sons, health, disease prevention, and hygiene were cited as major reasons for this preference. Cultural differences in preference were evident among some of the studies examined. Nevertheless, a preference for a circumcised penis was seen in most populations regardless of the frequency of MC in the study setting.
CONCLUSION
Women's preferences generally favor the circumcised penis for sexual activity, hygiene, and lower risk of infection. The findings add to the already well-established health benefits favoring MC and provide important sociosexual information on an issue of widespread interest.
