Arterial priapism, rare and often traumatic, is generally associated with cavernous arterial lesions. We report an unprecedented case in a 17-year-old adolescent, occurring spontaneously after severe dengue, expanding the understanding of this pathology. No similar association has been previously documented in the literature. The patient was successfully treated with conservative measures, and erections returned to normal. Dengue, by causing vascular leaks, could be a rare trigger for arterial priapism. Further studies are needed to elucidate these mechanisms and potential clinical implications.

Review
BACKGROUND AND OBJECTIVE
Implantation of penile prosthesis (PP) into scarred and fibrotic corpora can be a difficult challenge. In this review article, we provide a review of penile fibrosis, discuss current medical and surgical management and summarize preventative strategies.
METHODS
In this study, we searched PubMed between the years 2000-2023 for publications with search strategy: "penile fibrosis" OR "scarred corpora" OR "fibrosed corpora".
KEY CONTENT AND FINDINGS
This search returned a total of 137 articles. We examine the evidence for preoperative patient evaluation and penile ultrasound (US), oral phosphodiesterase-5 inhibitors, pentoxifylline, and L-arginine, vacuum device therapy and the use of surgical approaches and tools in the context of complex penile fibrosis cases. Severe penile fibrosis is most associated with priapism and infection. Estimating the degree of fibrosis via preoperative US may help set realistic patient expectations. Phosphodiesterase inhibitors and L-arginine reduce fibrosis in animal models however their impact in humans remains unclear despite theoretical advantage for their use. Vacuum device therapy may preserve penile length following priapism and infected PP cases. The use of Coloplast Narrow-Based or AMS-700 CXR implants are used primarily for severe fibrosis. Various surgical excisional/incisional techniques, the Carrion-Rossello, Mooreville Uramix cavernotomes and reverse cutting scissors are all options, and their use varies from case to case. Finally, prevention of penile fibrosis in patients with history of penile implant infection and the safety of early implantation of a penile implant in patients with refractory priapism is encouraged.
CONCLUSIONS
The management of penile fibrosis remains a challenge but there are multiple options to assist clinicians. Complex cases should be managed and studied at high volume centers.

Review
Priapism, defined as a prolonged and often painful penile erection occurring without sexual stimulation or desire, is a common complication in sickle cell disease (SCD), affecting up to 48% of male patients. This condition presents significant clinical challenges and can lead to erectile dysfunction if not properly managed. Current pharmacological treatments for SCD-related priapism are primarily reactive rather than preventative, highlighting a gap in effective medical intervention strategies. A critical factor in developing priapism is the reduced basal bioavailability of nitric oxide (NO) and cyclic guanosine monophosphate (cGMP) in erectile tissues. New prevention strategies should ideally target the underlying pathophysiology of the disease. Compounds that stimulate and activate soluble guanylate cyclase (sGC) emerge as potential therapeutic candidates since these compounds have the property of inducing cGMP production by sGC. This review explores the potential of sGC stimulators and activators in treating priapism associated with SCD. We discuss the advantages of these agents in the face of the challenging pathophysiology of SCD. Additionally, the review underscores the impact of intravascular hemolysis and oxidative stress on priapism pathophysiology in SCD, areas in which sGC stimulators and activators may also have beneficial therapeutic effects.

A 29-year-old man developed priapism following the (re)administration of zuclopentixol. In the previous days, a significant amount of alcohol was consumed, presumably in combination with amphetamine and cannabis. Priapism is a rare but serious side effect of various psychoactive medications and recreational drugs, leading to permanent loss of erectile function if not treated in time. In this case the side effect was discovered in a late stage, at which curative treatment was no longer viable. A clear guideline for choosing an alternative antipsychotic agent is currently lacking, but an antipsychotic with low alfa-adrenergic affinity seems preferable. To prevent erectile disfunction following priapism, awareness of its severity is essential, for both doctor and patient.

INTRODUCTION
Ischemic priapism is a medical emergency that, if not treated, could lead to permanent erectile dysfunction. The association between cocaine and priapism is well-known; however, data on patient characteristics, treatment, and outcomes is missing. This work aimed to answer the research question: What are the characteristics, management strategies, and erectile prognosis of patients consuming cocaine and presenting with priapism?
METHODS
We conducted a systematic review according to PRISMA guidelines and described our case series.
RESULTS
Eight studies were selected for qualitative synthesis, presenting information on ten patients. In our case series, we showed information regarding four patients. From the systematic review, the mean presentation time was 42.6 h, and the mean number of procedures to solve priapism was 2,4; in our case series was 42.75 h and 2, respectively.
CONCLUSION
Cocaine-related priapism might present with a delayed diagnosis, need more procedures to be managed, and have a worse prognosis. More extensive and prospective studies are required.

Sexual Medicine Feb 2024Cell therapy (CT) is a form of regenerative medicine under investigation for the management of male sexual dysfunction (MSD).
BACKGROUND
Cell therapy (CT) is a form of regenerative medicine under investigation for the management of male sexual dysfunction (MSD).
AIM
We sought to perform a systematic review of published information on CT for MSD and provide an official position statements for the European Society for Sexual Medicine.
METHODS
A comprehensive bibliographic search on the MEDLINE, Web of Science, Scopus, and Cochrane Library databases was conducted in February 2023. Articles were selected based on the Population, Intervention, Comparator, Outcome, Study design (PICOS) model if they included male patients (P) undergoing CT (I) with or without comparison with other treatments (C) and evaluated the impact of CT on sexual function (O). Quantitative data were reported as found in the original studies (S). Level of evidence and grade of recommendation according to the Oxford Centre for Evidence-Based Medicine were assigned to each statement.
OUTCOMES
Outcomes were determined based on assessment of erectile function, ejaculatory function, orgasmic function, sexual desire, and penile curvature.
RESULTS
A total of 19 studies and 421 patients were included. Most articles (n = 12, 63%) were case series, whereas a minority of papers (n = 6, 32%) had a comparative group; only 2 articles reported randomized controlled trials (RCTs) and 1 article reported a post hoc analysis of RCTs. Most articles (16, 84%) investigated patients with erectile dysfunction (ED). Improvements in the International Index of Erectile Function-Erectile Function Domain (IIEF-EF) or the IIEF 5-item version (IIEF-5) were found in 11/15 (73%) studies, with mean increases in IIEF-EF, mean IIEF-5, and median IIEF-EF between 8 and 14 points, 2 and 9 points, and 4.5 and 6 points, respectively. Two papers (20%) evaluated men with Peyronie's disease (PD). In both ot these articles penile curvature improvement and plaque volume reduction were described in all patients (n = 16, 100%). Objective measurements were performed in 1 study, which showed 10°-120° (15%-100%) curvature improvement and 90%-100% plaque reduction. Mild transient adverse events at the donor or administration sites were found in 7/16 (44%) papers on ED. Priapism was reported in one case (20%) and mild penile skin complications were reported in the majority of patients after CT for PD. No severe adverse events were described.
CLINICAL IMPLICATIONS
Although high-quality evidence is lacking, CT appears to have potential benefits from application in patients with ED or PD.
STRENGTHS AND LIMITATIONS
This report is to our knowledge the most comprehensive and up-to-date systematic review on the topic of CT for the management of MSD, including the position statements of the European Society for Sexual Medicine. Overall the assessment of available studies demonstrated low quality and significant heterogeneity.
CONCLUSION
Preliminary findings support potential efficacy and safety of CT in patients with ED or PD. Low-quality papers, high methodological heterogeneity, uncertainty about the magnitude of the beneficial effects, and lack of long-term data limit the available evidence.
