Artificial Intelligence (AI) applications have shown promise in the management of pandemics. In response to the global Monkeypox (Mpox) outbreak, the HeHealth.ai team leveraged an existing tool to screen for sexually transmitted diseases (STD) to develop a digital screening test for symptomatic Mpox using AI. Before the global Mpox outbreak, the team developed a smartphone app (HeHealth) where app users can use a smartphone to photograph their own penises to screen for symptomatic STD. The AI model initially used 5000 cases and a modified convolutional neural network to output prediction scores across visually diagnosable penis pathologies including syphilis, herpes simplex virus, and human papillomavirus. A total of about 22,000 users had downloaded the HeHealth app, and ~21,000 images were analysed using HeHealth AI technology. We then used formative research, stakeholder engagement, rapid consolidation images, a validation study, and implementation of the tool. A total of 1000 Mpox-related images had been used to train the Mpox symptom checker tool. Based on an internal validation, our digital symptom checker tool showed specificity of 87% and sensitivity of 90% for symptomatic Mpox. Several hurdles identified included issues of data privacy and security for app users, initial lack of data to train the AI tool, and the potential generalisability of input data. We offer several suggestions to help others get started on similar projects in emergency situations, including engaging a wide range of stakeholders, having a multidisciplinary team, prioritising pragmatism, as well as the concept that 'big data' in fact is made up of 'small data'.

The main goal of the present study was to analyze the expression profile of cyclin D1 in patients with PC, and to determine possible correlations with clinical and histopathological features. A survey was conducted with 100 patients diagnosed with PC, who were treated at two reference hospitals in São Luís, Maranhão, Brazil, between 2013 and 2017. A review of clinical, epidemiological, and histopathological data was performed, Human Papillomavírus (HPV) DNA was detected using polymerase chain reaction (PCR) and cyclin D1 expression analysis was performed using immunohistochemical techniques. The data revealed that the absence of cyclin D1 expression was significantly associated with HPV-positive histological subtypes ( = 0.001), while its expression was associated with high-grade tumors ( = 0.014), histological subtype ( = 0.001), presence of sarcomatoid transformation ( = 0.04), and perineural invasion ( = 0.023). Patients with cyclin D1 expression exhibited lower disease-free survival compared to the cyclin D1-negative group, although the difference was not statistically significant. The results suggest that cyclin D1 may be a potential biomarker for PC, especially for poorer prognosis.

Randomized Controlled Trial
BACKGROUND
The effect of the periurethral cleansing range on catheter-associated urinary tract infection (CAUTI) occurrence remains unknown. The purpose of this study was to evaluate the efficacy of expanded periurethral cleansing for reducing CAUTI in comatose patients.
METHODS
In this randomized controlled trial, eligible patients in our hospital were enrolled and allocated randomly to the experimental group (expanded periurethral cleansing protocol; n = 225) or the control group (usual periurethral cleansing protocol; n = 221). The incidence of CAUTI on days 3, 7, and 10 after catheter insertion were compared, and the pathogen results and influencing factors were analyzed.
RESULTS
The incidences of CAUTI in the experimental and control groups on days 3, 7, and 10 were (5/225, 2.22% vs. 7/221, 3.17%, P = 0.54), (12/225, 5.33% vs. 18/221, 8.14%, P = 0.24), and (23/225, 10.22% vs. 47/221, 21.27%, P = 0.001), respectively; Escherichia coli and Candida albicans were the most common species in the two groups. The incidences of bacterial CAUTI and fungal CAUTI in the two groups were 11/225, 4.89% vs. 24/221, 10.86%, P = 0.02) and (10/225, 4.44% vs. 14/221, 6.33%, P = 0.38), respectively. The incidences of polymicrobial CAUTI in the two groups were 2/225 (0.89%) and 9/221 (4.07%), respectively (P = 0.03). The percentages of CAUTI-positive females in the two groups were 9.85% (13/132) and 29.52% (31/105), respectively (P < 0.05). The proportion of CAUTI-positive patients with diabetes in the experimental and control groups was 17.72% (14/79), which was lower than the 40.85% (29/71) in the control group (P < 0.05).
CONCLUSION
Expanded periurethral cleansing could reduce the incidence of CAUTI, especially those caused by bacteria and multiple pathogens, in comatose patients with short-term catheterization (≤ 10 days). Female patients and patients with diabetes benefit more from the expanded periurethral cleansing protocol for reducing CAUTI.

Review
INTRODUCTION
The microbiota is defined as the microorganisms in a particular environment. Conversely, the term microbiome is less firmly defined and is used to reference the habitat.
OBJECTIVE
To identify the association between the microbiome and the penile cancer EVIDENCE ACQUISITION: We performed this scoping review according to the recommendations of the Joanna Briggs Institute. We found five articles that fulfilled the inclusion criteria. We focused on oncogenesis and factors that alter the penile microbiome. We were not limited to language or setting. We searched MEDLINE (Ovid), Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and LILACS from inception to the present day.
EVIDENCE SYNTHESIS
We found nine studies describing multiple factors that could disturb the microbiome, such as sexual behavior, anatomic alterations including circumcision, and inflammatory factors: lichen sclerosus, poor genital hygiene, compromised immune system, smoking, and HPV infection.
CONCLUSION
Overall, knowledge of the composition of the penile microbiota and its role in penile cancer oncogenesis is minimal.
PATIENT SUMMARY
Future studies should focus on the relationship between the microbiome and penile cancer to broaden this field of knowledge.

Review
BACKGROUND AND OBJECTIVE
Since immediate salvage (IS) surgery for infected penile prosthesis (PP) was introduced nearly 30 years ago, an abundance of evidence has emerged in support of its use. IS remains underutilized by the modern urologist despite its distinct advantages. While some medical literature proposes reasons for the underuse of IS, no comprehensive review attempts to address the numerous factors limiting its implementation. Our objective is to analyze the barriers to IS surgery for infected PP with the goal of expanding utilization of this technique through a practical and standardized approach for treating urologists.
METHODS
A narrative review of available English, peer-reviewed, medical literature relevant to the barriers to IS was completed. Searches were expanded to include literature from surgical specialties in general if hypothesized barriers were incompletely described in available PP publications.
KEY CONTENT AND FINDINGS
The major barriers that are likely contributing to the low rates of IS for PP surgery can be broadly classified into three major categories: institutional/systemic, medical/surgical, and patient preference. Institutional/systemically driven barriers include surgeon comfort with PP surgery, low national availability of urologists, inaccessibility of prosthetics or critical ancillary staff at the time of patient presentation and limited operating room (OR) access. Medical/surgical barriers primarily relate to reinfection fears, perceived contraindications to IS, and overall patient stability at the time of presentation. Patient preference factors inhibiting IS involve loss of trust in the medical team, psychosocial distress, dissatisfaction with the initial device prior to infection and anxiety regarding postoperative recovery. Many of the identified barriers can be overcome with increased surgical training, improved patient and surgeon understanding of PP infection, or precautionary planning.
CONCLUSIONS
Of the factors that contribute to low utilization of IS, many are misunderstood or unknown. Recognition of these barriers may equip urologists to provide better care to patients with prosthesis infection.

Review
BACKGROUND AND OBJECTIVE
Implantation of a penile prosthesis is a reliable option for men with erectile dysfunction (ED) refractory to less invasive therapies. While the frequency of penile prosthesis infections have decreased, they remain a devastating complication. Herein we discuss why immediate salvage surgery is an essential technique for the management of implant infections. We will also describe the relevant advancements to this technique.
METHODS
We conducted a narrative review via computer based search of PubMed for all relevant articles on penile prosthesis infection management, including guidelines, case series, reviews, and expert opinions. Search terms used included: "inflatable penile prosthesis", "IPP", "penile prosthesis", "salvage", "treatment", "delayed", "immediate". Only English peer-reviewed publications were included.
KEY CONTENT AND FINDINGS
Historically, patients who presented with penile prosthesis infections were exclusively managed with complete removal of the prosthesis without replacement. Although this strategy is safe, it hastens immediate ED and corporal fibrosis, resulting in loss of penile length and increased difficulty with subsequent prosthesis replacement. Previous case series have reported successful treatment of localized penile prosthesis infections with nonsurgical treatment, but the role of conservative treatment remains limited. The current standard of immediate salvage entails removal of the infected prosthesis and washout followed by immediate replacement with a new penile prosthesis. This technique has been demonstrated to be safe and effective, thus allowing patients to resume intercourse and maintain penile length.
CONCLUSIONS
Immediate salvage surgery is safe and effective, and has emerged as the preferred strategy for the management of most patients with a penile prosthesis infection.

Review
BACKGROUND
Priapism is a rare condition characterized by persistent erection of the penis that lasts more than 4 hours in the absence of sexual stimulation and is associated with significant morbidity and complications, including erectile dysfunction and penile fibrosis. Surgical management of priapism can be extremely challenging. We herein provide a comprehensive review that aims to evaluate the role of penile prosthesis (PP) implantation in the management of priapism.
METHODS
A systematic literature search was performed using the following databases: PubMed, Embase, and Scopus to identify studies that evaluated the effectiveness of PP implantation in treating priapism and the long-term complications, outcomes, and patients' satisfaction rate.
RESULTS
Out of 717 English-language studies published between 2002 and 2022, 17 were chosen for this review. Majority of patients had a malleable PP (MPP) implant, either early or delayed after the priapism episode. Early placement (EP) of PP is widely defined between studies ranging from less than 72 hours, within 1 week, and within 3 weeks. Most common causes of priapism were sickle cell anemia (SCA), medication-induced, and idiopathic. Studies show a higher satisfaction rate ranging between 80% and 100%, with sexual intercourse achievement ranging between 64.2% and 100%. Based on the GRADE system, included studies rated as very low quality of evidence. Commonly reported complications that arise after PP procedures, include device infection, erosion, curvature, and mechanical malfunction, such as auto-inflation.
CONCLUSIONS
PP can be an effective treatment option for priapism, particularly in cases of ischemic priapism lasting more than 36 hours or recurrent priapism that is medically refractory. However, due to the very low quality of evidence, larger, well-designed studies are warranted where long-term outcomes, patients' satisfaction, and complications following priapism-related PP implantation are measured as endpoints.

Review
Ischemic priapism is a urological emergency which may lead to irreversible erectile dysfunction. One of the accepted treatments is penile prosthesis implantation. Given the scarcity of studies directly comparing timing of penile prosthesis insertion after ischemic priapism, consensus remains elusive. We aim to compare different studies in the literature concerning advantages and disadvantages of early versus delayed inflatable penile prosthesis following ischemic priapism. We analyzed 8 articles that investigated immediate and delayed inflatable penile prosthesis placement after ischemic priapism. Early inflatable penile prosthesis placement is associated with better outcomes, including pain relief, priapism resolution, penile shortening prevention, and quicker sexual activity resumption. However, it still carries a high risk of complications like edema, infection, and distal perforations. Delayed inflatable penile prosthesis insertion poses surgical challenges due to the potential for extensive corporal fibrosis. Comparative analyses have shown elevated complication rates in patients with ischemic priapism who undergo delayed inflatable penile prosthesis insertion, as opposed to those with early insertion. In studies reporting complications rates, the total complication rate in the early group was 3.37%, significantly lower than the delayed group (37.23%). Most studies support the superiority of early inflatable penile prosthesis placement following ischemic priapism over delayed placement. Further research is, however, needed to establish a global consensus on timing of prosthesis insertion.

A 33-year-old man presented with suprapubic abdominal pain and small vesicular lesions on the foreskin of the penis. Based on the presentation, he was empirically treated for genital herpes, although the herpes simplex virus swab was negative. He returned to the emergency department 4 months after his initial presentation with worsening symptoms that were consistent with balanoposthitis and cystitis. He was tachycardic and febrile on presentation. He denied any sexual contact for the last 3 months, with previous negative screening tests for sexually transmitted infections. Syphilis was eventually diagnosed during this admission. The incidence rates of syphilis have increased in recent years, and the infection is often undiagnosed given atypical manifestations. Here we present an atypical manifestation of syphilis that was initially misdiagnosed as herpes simplex virus.

Purpose Hypospadias is an anomaly wherein the urethral opening is ectopically located on the ventral aspect of the penis. The most common complications after hypospadias repair are urethrocutaneous fistula (UCF) and meatal stenosis. Long Chain Cyanoacrylate (LCCA) tissue adhesive promises safety, feasibility, and durability due to its tensile strength and bacteriostatic and hemostatic properties. We conducted this study to ascertain whether LCCA tissue adhesive can prove a more effective adjunct to traditional suturing techniques. Methods Patients were divided into two groups. Group A underwent surgery with conventional reconstruction of the neourethral tube along with the buttressing layer using Buck's fascia or Tunica Vaginalis. In addition to the traditional procedure of Group A, Group B patients were administered a layer of LCCA tissue adhesive as an adjunct between the neourethral suture line and the buttressing layer. Patients were followed up for six months and were evaluated for complications like UCF, meatal stenosis, hematoma, skin infection, glans dehiscence, and flap necrosis. Results Thirty-eight children in the age group 1-6 years were studied, of which 20 were in Group A and 18 in Group B. Among patients of Group A seven (35%) developed complications. In contrast, only four (22.2%) patients developed complications in Group B. The statistical significance in the complication rates between the two groups could not be achieved due to the modest sample size. However, the numerical and proportional reduction in the number of complications was noted. Conclusion LCCA adhesive as an adjunct numerically reduces the number of complications compared to traditional suturing alone in patients undergoing surgery for hypospadias and UCF.
