Prospective data are limited on human papillomavirus (HPV) acquisition and clearance among circumcised men from resource-limited geographical regions, particularly Africa. The goal of this study was to estimate incidence and clearance of type-specific genital HPV infection in men. Penile exfoliated cell specimens were collected from the glans/coronal sulcus and shaft of 1,037 circumcised Kenyan men at baseline and 6-, 12- and 18-month follow-up visits between 2003-2007. Specimens were tested with GP5+/6+ PCR to detect 44 HPV types. The median age of participants at baseline was 21 years (range 18-28). The 12- and 18-month incidence rates (IRs) for any HPV were 34.9/100 person-years (95% confidence interval [CI]: 31.2-39.0) and 36.4/100 person-years (95% CI: 32.9-40.2), respectively. The 18-month cumulative risk for high-risk HPV was 30% compared to 16% for low-risk HPV. Cumulative risk was not associated with age or anatomical site. The estimated probability of any HPV infection clearing by 12 months was 0.92. Time until HPV clearance was not associated with age, anatomical site, or whether HPV infection type was high-risk or low-risk. HPV IRs among circumcised men in this study were comparable to other circumcised populations.

Observational Study
BACKGROUND
Post-circumcision penile ischemia is a devastating complication. We will present our experience in managing children with various forms of penile ischemia.
MATERIALS AND METHODS
This cohort prospective observational and interventional study was performed on all male children with post-circumcision penile ischemia between April 2017 and October 2021. A designed and approved protocol includes a combination of early pentoxifylline infusion, hyperbaric oxygen inhalation, early catheterization, and appropriate surgical debridement were applied for patients with deep ischemia 11/23, mainly the necrotic skin and subcutaneous tissues. Data of patient age, anesthesia method, monopolar diathermy usage, early presentation and positive wound culture were collected and analyzed statistically.
RESULTS
During the study period 3,382 children were circumcised for non-medical reasons; 23 children were diagnosed with penile ischemia (0.7%), among other complications (9%). Most of the penile ischemia is associated with the use of monopolar diathermy (74%). The use of compressive wound dressing to control post-circumcision bleeding and infections is also responsible for ischemia in 52.2% and 43.5% of the cases. Inexperienced physicians were commonly responsible for ischemia (73.9%). Patients managed at first 24 h had better outcomes than those who were presented later (p = 0.001).
CONCLUSION
In children with post-circumcision penile ischemia, a combination of hyperbaric oxygen therapy and pentoxifylline is especially effective for patients with skin and facial necrosis, this management reduces penile tissue loss.

BACKGROUND
Phimosis, a common paediatric condition, is defined as the inability to retract the preputial skin behind the glans. Current practice shows there is some confusion among the paediatricians towards this common condition and in differentiating it from the more common physiological preputial adhesion; leading to frequent referrals to a paediatric surgeon or a general surgeon, which can be addressed by the parents and the child physicians themselves.
AIM
To find out the awareness towards the management of phimosis among the paediatricians.
MATERIALS AND METHODS
A questionnaire on this topic was generated using 'Google Forms' and was circulated among junior and senior residents, faculty in various medical colleges and consultants in private practice all over India and their response was collected and analysed.
RESULTS
We received a total of 221 responses from all over India from paediatric medicine trainees and consultants. Among them, majority (48%) were senior residents. According to the survey participants, the most (46%) find inability to retract the prepuce as the major presenting complaint. A straight away reference to a paediatric surgeon was preferred by majority of paediatricians (62.9%), though most of them were aware of them were aware of physiological adhesions and conservative management (94.2%). There was a belief among 43% about counselling each and every patient presenting with phimosis for circumcision. Among the respondents, 60.2% advised ultrasound of kidneys, ureter, and bladder to their patients and believed that backpressure changes alter the management of the child. A urine routine examination was advised by 70.1% of participants, with 46.6% believing that the presence of urinary tract infection changes the management of phimosis. Waiting up to 1 year of age before going for surgery was advocated by 71.5%. A major proportion of respondents (76%) believed all cases of phimosis should be referred to a surgeon, only 58.8% would voluntarily follow them up. There is still a belief among 69.7% of participants that all cases of phimosis should be referred to a paediatric surgeon and only few of them, 5.4% feel referring only indicated cases.
CONCLUSION
Physiological phimosis is a common condition which can be addressed by the paediatricians themselves. Awareness is to be increased among them, especially during the training period regarding the proper management of this common condition, avoiding unnecessary circumcisions.

Review
The purpose of this study is to investigate the relationship between inflatable penile prosthesis (IPP) infection, time of year, climate, temperature and humidity. This is a retrospective IRB-approved analysis of 211 patients at 25 institutions who underwent salvage procedure or device explant between 2001 and 2016. Patient data were compiled after an extensive review of all aspects of their electronic medical records. Climate data were compiled from monthly norms based on location, as well as specific data regarding temperature, dew point, and humidity from dates of surgery. Rigorous statistical analysis was performed. We found that penile prosthesis infections occurred more commonly in June (n = 24) and less frequently during the winter months (n = 39), with the lowest number occurring in March (n = 11). One-hundred thirty-nine infections occurred at average daily temperatures greater than 55 °F, compared to 72 infections at less than 55 °F. The incidence rate ratio for this trend was 1.93, with a p-value of <0.001. Humidity results were similar, and fungal infections correlate with daily humidity. Infected implants performed in the fall and summer were over 3 and 2.3 times, respectively, more likely to grow Gram-positive bacteria compared to implants performed in spring (p = 0.004; p = 0.039). This was consistent across geographic location, including in the Southern hemisphere. We found trends between climate factors and IPP infection like those seen and proven in other surgical literature. To our knowledge these data represent the first exploration of the relationship between temperature and infection in prosthetic urology.

Meta-Analysis Review
Prevalence and genotype distribution of human papillomavirus infection in different anatomical sites among men who have sex with men: A systematic review and meta-analysis.
Men who have sex with men (MSM) are at increased risk of human papillomavirus (HPV) infection because of their high-risk sexual behaviours. In this study, a meta-analytic approach was used to systematically analyse the literature to elucidate the prevalence and genotype distribution of anal, penile, oral and urethral HPV infection among MSM in the world. To carry out this systematic review, five electronic databases including Web of Science, PubMed, Scopus, Embase, and Google Scholar were searched for relevant studies published from January 2012 to November 2019, and pertinent data were collected from the eligible articles. The pooled HPV prevalence was calculated for each anatomical region using a random-effect model weighted by the inverse variance method. The meta-analysis was performed using the "Metaprop" function in the R package Meta. The overall pooled prevalence of anal, penile, oral and urethral HPV infection among MSM were 78.4% (95% confidence interval [CI]: 75.6%-81.0%), 36.2% (95% CI: 29.1%-44.0%), 17.3% (95% CI: 13.6%-21.7%) and 15.4% (95% CI: 7.8%-27.9%), respectively. Stratified analyses showed that the prevalences of HPV were significantly higher in HIV-positive than HIV-negative MSM. The most frequent HPV high-risk type detected in the anus, penis and oral cavity was HPV-16 (19.9%, 4.9% and 3.1%, respectively). HPV infection is rising in MSM because of high-risk sexual behaviours, suggesting an increased future risk of developing HPV-related diseases and malignancies in this population.

Penile implants are surgically inserted devices used for the treatment of erectile disfunction. Improvements in surgical techniques and in the manufacturing of these implants have reduced the risk of intra- and postoperative complications and increased the popularity and use of this therapeutic option. Routine imaging is not recommended before penile prosthesis surgery. Malleable penile prostheses use noninflatable shafts inserted into each corpus cavernosum, which appear hypointense on T1- and T2-weighted MR images. Inflatable penile prostheses (IPPs) may consist of two or three parts and are composed of two cylinders inserted into the corpora cavernosa that are filled with a saline solution to produce rigidity. These appear homogeneously T2 hyperintense and the silicone-based covering of the cylinders appears T2 hypointense, thereby clearly delineating the cylinders. In the case of three-piece IPPs, a reservoir containing the fluid may be placed in the pelvis. The most frequent complications are related to infection and mechanical failure, the latter being more common in IPPs because more components are involved. Less common complications include malpositioning. Detection and management of postoperative complications are challenging, and MRI plays a crucial role as it permits evaluation of the positioning and configuration of the prosthesis components, as well as assists in functional evaluation of IPPs when images are obtained of both the flaccid and inflated states.

INTRODUCTION
Management for distal impending erosion can be difficult and has been previously managed with counter incisions which can lead to unsightly scars and increased infection risk.
AIM
To demonstrate a novel technique in management of impending erosion.
METHODS
We retrospectively reviewed patients who underwent placement of a distal biologic cap for impending erosion.
MAIN OUTCOME MEASURE
The main outcome was thesuccessful placement of inflatable penile prosthesis through a single incision.
RESULTS
All patients who underwent this procedure are functional and have had no evidence of recurrence.
CLINICAL IMPLICATIONS
A simple approach to manage impending distal erosion.
STRENGTH & LIMITATIONS
Limitations include small sample size and short duration of follow-up.
CONCLUSION
The distal biologic cap is a simple alternative technique to treat distal impending erosion of an inflatable penile prosthesis and can be performed safely without the need for additional incisions on the penis and with a minimal increase in operative times.

BACKGROUND
To date, the microbiota of the human penis has been studied mostly in connection with circumcision, HIV risk and female partner bacterial vaginosis (BV). These studies have shown that male circumcision reduces penile anaerobic bacteria, that greater abundance of penile anaerobic bacteria is correlated with increased cytokine levels and greater risk of HIV infection, and that the penile microbiota is an important harbour for BV-associated bacteria. While circumcision has been shown to significantly reduce the risk of acquiring human papillomavirus (HPV) infection, the relationship of the penile microbiota with HPV is still unknown. In this study, we examined the penile microbiota of HPV-infected men as well as the impact of HIV status.
RESULTS
The penile skin microbiota of 238 men from Cape Town (South Africa) were profiled using Illumina sequencing of the V3-V4 hypervariable regions of the 16S rRNA gene. Corynebacterium and Prevotella were found to be the most abundant genera. Six distinct community state types (CSTs) were identified. CST-1, dominated by Corynebacterium, corresponded to less infections with high-risk HPV (HR-HPV) relative to CSTs 2-6. Men in CST-5 had greater relative abundances of Prevotella, Clostridiales, and Porphyromonas and a lower relative abundance of Corynebacterium. Moreover, they were significantly more likely to have HPV or HR-HPV infections than men in CST-1. Using a machine learning approach, we identified greater relative abundances of the anaerobic BV-associated bacteria (Prevotella, Peptinophilus, and Dialister) and lower relative abundance of Corynebacterium in HR-HPV-infected men compared to HR-HPV-uninfected men. No association was observed between HIV and CST, although the penile microbiota of HIV-infected men had greater relative abundances of Staphylococcus compared to HIV-uninfected men.
CONCLUSIONS
We found significant differences in the penile microbiota composition of men with and without HPV and HIV infections. HIV and HR-HPV infections were strongly associated with greater relative abundances of Staphylococcus and BV-associated bacterial taxa (notably Prevotella, Peptinophilus and Dialister), respectively. It is possible that these taxa could increase susceptibility to HIV and HR-HPV acquisition, in addition to creating conditions in which infections persist. Further longitudinal studies are required to establish causal relationships and to determine the extent of the effect.

Review
We aimed to review all information on penile prosthetic surgery in patients with prior phalloplasty and give a detailed description of the authors's preferred technique. A nonsytematic review of the articles that were published in English and indexed on Pubmed, Google Scholar, and Embase databases was conducted. The relevant literature reports mainly on the outcomes of penile prosthesis (PP) implantation following gender affirming phalloplasty with the radial forearm free flap technique. Three-piece inflatable penile prostheses (IPP) have been the most commonly utilized hardware in this setting. PP implantation in a neophallus is a complex procedure and contains some technical nuances. Creation of spaces within the neophallus for the cylinder(s), wrapping the cylinder(s) with synthetic materials or allografts, and fixation of the prosthesis to the pubic bony structures can be considered as the most important steps of this procedure. Five-year IPP retention rates in flap phalloplasty range between 42 and 78% which is lower than the rate observed in anatomic phallus. In addition, complication and mechanical failure rates are higher in flap phalloplasty. However, satisfaction rates after PP implantations in anatomic penis versus neophallus seem to be similarly high. Infection, migration, and mechanical failure are the most frequent complications.

Infection by COVID-19, being a respiratory disease caused by SARS-CoV-2, can predispose to arterial and venous thrombotic disease, in response to excessive inflammation, platelet activation, endothelial dysfunction, and venous stasis. During the COVID-19 pandemic period, the technological and resource availability for the care of these patients with thrombotic disease is critical, marking a factor of morbidity and poor prognosis in these cases. We describe a case of priapism in a patient with COVID-19, during the course of systemic inflammatory response syndrome and respiratory distress syndrome with a procoagulant state, seeking to relate the pathophysiological factors of ischemic priapism in patients with infection with SARS-Cov-2.
