BACKGROUND
Penile Mondor disease is a superficial dorsal vein thrombophlebitis of the penis, which mainly affects young and middle-aged men. It generally manifests as a visible painful cord located along the dorsal surface of the penis with signs of skin inflammation. The condition is usually self-limiting, but in severe cases a surgical procedure may be necessary in addition to pharmacological treatment. Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 is associated with a frequent incidence of thrombophilia; therefore, such a prothrombotic state during infection may be a significant risk factor for penile Mondor disease.
CASE PRESENTATION
The 34-year-old patient reported moderate pain felt on the surface of the penis. During the medical interview, the patient did not admit significant risk factors for Mondor Disease, apart from the previous, a month earlier COVID-19 disease. Examination revealed swelling erythema and a thick indurated cord on the surface of the penis. Color Doppler ultrasound was performed to confirm assumptions and exclude thrombosis of other penile vessels. Based on visible clots in the course of the superficial penile vein and after exclusion of vasculitis due to autoimmune disease the diagnosis of penile Mondor disease was made. Pharmacological therapy was implemented to further break down the clot and prevent rethrombosis in the penile vessels. The patient did not report any treatment complications and returned for a control visit, which revealed complete clot dissolution on ultrasound; therefore, complete recovery was stated.
CONCLUSIONS
This case report presents the correlation between SARS-Cov-2 infection and penile Mondor disease, based on the confirmed influence of COVID-19 on the pathophysiology of thrombosis. It can be concluded that COVID- 19 is a risk factor for Mondor disease, as in the presented case the virus was the only prothrombotic risk factor for the patient. Consequently, the possibility of developing thrombosis in the form of penile Mondor disease should be taken into account among patients with post-COVID-19 and active SARS-Cov-2 infection.

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.

OBJECTIVES
To describe a novel technique for partial anatomic penile amputation using a thoracoabdominal stapler in dogs and to report any associated short-term peri-operative complications and clinical outcomes associated with the procedure.
MATERIALS AND METHODS
Medical records from a tertiary referral hospital were reviewed for dogs undergoing penile amputation and scrotal urethrostomy between October 2007 and December 2019. Data collected included patient signalment, clinical signs on presentation, indication for penile amputation, surgical technique, duration of surgery, post-operative complications, and short-term outcome.
RESULTS
Nine dogs were included in the study. Indications for surgery were for treatment of chronic paraphimosis and priapism (n = 3), recurrent urethral prolapse (n = 2), balanoposthitis (n = 1), masses arising from the penis, prepuce, and/or urethra (n = 2), and penile trauma (n = 1). All dogs underwent a scrotal urethrostomy followed by a partial penile amputation with a thoracoabdominal stapler. All dogs suffered mild post-operative haemorrhage from the urethrostomy stoma. On recovery from general anaesthesia, 2/9 dogs were painful and another 2/9 dogs were dysphoric. Two dogs experienced incisional complications with mild swelling around the urethrostomy stoma. One dog experienced an infection of the penile amputation site 21 days after surgery. The short-term outcomes for this procedure were excellent in 8/9 dogs. These outcomes were based on owner assessment of comfort and monitoring throughout the recovery period, manual palpation of the surgical site at the time re-evaluation, and surgeon visualization of successful voluntary urination 14-35 days after surgery.
CLINICAL SIGNIFICANCE
Use of a thoracoabdominal stapler is effective in achieving partial anatomic penile amputation in dogs.

BACKGROUND
Flat penile lesions (FPL) in heterosexual men are thought to play a role in the transmission of HPV. We investigated the association between FPL and penile HPV, and explored determinants of FPL in men who have sex with men (MSM).
METHODS
In 2015-2016, MSM were recruited based on HIV and penile HPV status in a previous cohort. MSM self-completed a questionnaire. Peniscopy was performed after application of acetic acid to visualize FPL. Penile physician-collected samples were tested for HPV-DNA using the highly sensitive SPF10-PCR DEIA/LiPA25 system. HPV viral load (VL) was determined using a quantitative type-specific (q)PCR targeting the L1-region. Presence of HPV and HIV, HPV VL and circumcision status were compared between MSM with and without FPL.
RESULTS
We included 116 MSM, of whom 59/116 (51%) MSM were HIV-positive and 54/116 (47%) had FPL. A penile HPV infection was present in 31/54 (57%) MSM with FPL and 34/62 (55%) MSM without FPL (p = 0.8). There was no difference between MSM with and without FPL regarding presence of penile HPV infection, HPV VL, HIV status or circumcision status (p > 0.05 for all).
CONCLUSION
Among MSM in Amsterdam, we found no association between FPL and penile HPV, HPV VL, HIV status or circumcision status.

Clinical Trial Randomized Controlled Trial
Sexual transmission of HIV requires exposure to the virus and infection of activated mucosal immune cells, specifically CD4 T cells or dendritic cells. The foreskin is a major site of viral entry in heterosexual transmission of HIV. Although the probability of acquiring HIV from a sexual encounter is low, the risk varies even after adjusting for known HIV risk factors. The genital microbiome may account for some of the variability in risk by interacting with the host immune system to trigger inflammatory responses that mediate the infection of mucosal immune cells. We conducted a case-control study of uncircumcised participants nested within a randomized-controlled trial of male circumcision in Rakai, Uganda. Using penile (coronal sulcus) swabs collected by study personnel at trial enrollment, we characterized the penile microbiome by sequencing and real-time PCR and cytokine levels by electrochemiluminescence assays. The absolute abundances of penile anaerobes at enrollment were associated with later risk of HIV seroconversion, with a 10-fold increase in , , , and increasing the odds of HIV acquisition by 54 to 63%, after controlling for other known HIV risk factors. Increased abundances of anaerobic bacteria were also correlated with increased cytokines, including interleukin-8, which can trigger an inflammatory response that recruits susceptible immune cells, suggesting a mechanism underlying the increased risk. These same anaerobic genera can be shared between heterosexual partners and are associated with increased HIV acquisition in women, pointing to anaerobic dysbiosis in the genital microbiome and an accompanying inflammatory response as a novel, independent, and transmissible risk factor for HIV infection. We found that uncircumcised men who became infected by HIV during a 2-year clinical trial had higher levels of penile anaerobes than uncircumcised men who remained HIV negative. We also found that having higher levels of penile anaerobes was also associated with higher production of immune factors that recruit HIV target cells to the foreskin, suggesting that anaerobes may modify HIV risk by triggering inflammation. These anaerobes are known to be shared by heterosexual partners and are associated with HIV risk in women. Therefore, penile anaerobes may be a sexually transmissible risk factor for HIV, and modifying the penile microbiome could potentially reduce HIV acquisition in both men and women.

BACKGROUND
Coronal sulcus (CS) anaerobe abundance and IL-8 levels are linked to HIV acquisition, and are dramatically reduced after penile circumcision (PC). The distal urethra may be the site of some HIV acquisition before PC, and presumably most acquisition post PC. We describe the immune milieu and microbiome of the distal urethra in uncircumcised Ugandan men, and define the impact of PC. Participants consisted of HIV-negative, genital symptom-free adult Ugandan men undergoing PC (n = 51). Urethral and coronal sulcus swabs were collected at baseline and at 6- and 12-months post-PC. Soluble immune factors were quantified by multiplex ELISA, and bacterial abundance assessed by 16S rRNA qPCR and sequencing.
RESULTS
At baseline, the urethra was enriched compared to the CS for most cytokines (including IL-8 and MIP-1β) and soluble E-cadherin (sE-cadherin, an epithelial disruption marker), although CS levels of IL-1α and IL-1β were higher. Baseline total bacterial abundance was ≥ 20-fold higher in the CS than the urethra (median 27,100 vs. 1200 gene copies/swab, p = 0.001), and anaerobes comprised 58% of CS bacteria vs. 42% of urethral bacteria. PC did not alter urethral IL-8 (median 806 at baseline vs. 1130 pg/ml at 12 months; p = 0.062) and urethral sE-cadherin increased (113,223 vs. 158,385 pg/ml, p = 0.009), despite five- and sevenfold drops in total bacterial and anaerobe abundance after PC, respectively. However, PC dramatically reduced CS levels of sE-cadherin (15,843 vs. 837 pg/ml, p < 0.001) and most cytokines (IL-8; 34 vs. 3 pg/ml, p < 0.001), while reducing total bacterial and anaerobe abundance by 13-fold and 60-fold, respectively (both P ≤ 0.004).
CONCLUSIONS
The urethra is immunologically rich with characteristics of an HIV-susceptible tissue site. However, PC had no impact on urethral immunology and may have reduced epithelial integrity, despite modest reductions in total bacteria and anaerobes, suggesting that HIV protection from PC is not mediated via immune or microbiome alterations in the urethra.

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.

Prostate abscess (PA) is an uncommon prostatic infection, with risk factors including indwelling catheters, acute or chronic prostatitis, bladder outlet obstruction, voiding dysfunction, recent urologic instrumentation (especially transrectal prostate biopsy), chronic kidney disease (CKD), diabetes mellitus (DM), human immunodeficiency virus (HIV), intravenous drug use (IVDU), and hepatitis C. Treatment of PA consists of antibiotics and abscess drainage via transurethral resection (TUR) or image-guided transrectal or transperineal drainage. Numerous studies have demonstrated that TUR of PA has a higher success rate and shorter hospital length of stay when compared to image-guided drainage. Despite this, TUR of PA is a relatively uncommon surgery with few useful recommendations on how to best perform this procedure. We demonstrate the TUR surgical technique for drainage of a 6 cm loculated PA in a 44-year-old man with active IVDU and hepatitis C. The patient presented with progressive voiding symptoms, urinary retention, and leukocytosis. Given the size, loculated nature of the abscess, and its proximity to the prostatic urethra, we decided to proceed to the operating room for surgical drainage as opposed to image-guided transrectal drainage. Herein we describe the trans urethral technique. He clinically improved postoperatively and repeat imaging 4 days later showed decreased abscess size. Transurethral drainage of a PA is a safe, efficient, and effective treatment option. Treatment approach should depend on abscess size, location, and presence of loculations. Combining different endourologic techniques and instruments may be necessary.
