REVIEW
Justin M Hintze, James P O'Neill
PURPOSE: The purpose of this review is to highlight the benefits of gender-neutral and the nonavalent human papillomavirus vaccination. Human papillomavirus infection is the most commonly sexually transmitted disease and is known to cause several types of cancers, including cervical, vulvar, vaginal, penile, oropharyngeal, anal, and rectal. 5% of cancers every year are attributable to human papillomavirus infection, with cervical cancer the most common and oropharyngeal cancer estimated to surpass the incidence of cervical cancer by 2020...

The Tumor-Node-Metastasis (TNM) classification on cancer staging, jointly developed by the American Joint Commission on Cancer (AJCC) and the Union for International Cancer Control (UICC), has been updated to its 8th edition with two contemporaneous versions published by the AJCC and UICC. While the goal of the AJCC and UICC is to have identical TNM staging systems, differences exist between these two publications including in the staging of urologic cancers. Among several new facets in the AJCC staging manual, a select few of greater import include an expanded section on imaging, presentation of levels of evidence for significant changes, and endorsement of risk assessment models that pass the AJCC quality criteria such as in prostate cancer...

Calpain activation contributes to hyperglycemia-induced endothelial dysfunction and apoptosis. This study was designed to investigate the role of calpain inhibition in improving diabetic erectile dysfunction (ED) in mice. Thirty-eight-week-old male C57BL/6J mice were divided into three groups: (1) nondiabetic control group, (2) diabetic mice + vehicle group, and (3) diabetic mice + MDL28170 (an inhibitor of calpain) group. Type 1 diabetes was induced by intraperitoneal injection of streptozotocin at 60 mg kg-1 body weight for 5 consecutive days...

Penile fibrosis caused by ischemic priapism (IP) adversely affects patients' erectile function. We explored the role of lysyl oxidase (LOX) in rat and human penes after ischemic priapism (IP) to verify the effects of anti-LOX in relieving penile fibrosis and preventing erectile dysfunction caused by IP in rats. Seventy-two rats were randomly divided into six groups: control group, control + β-aminopropionitrile (BAPN) group, 9 hrs group, 9 hrs + BAPN group, 24 hrs group, and 24 hrs + BAPN group. β-aminopropionitrile (BAPN), a specific inhibitor of LOX, was administered in the drinking water...

Erectile dysfunction (ED) has been reported to be associated with inflammation. This study investigated the effects of tumor necrosis factor alpha (TNF-α) inhibitor etanercept on penile neuronal nitric oxide synthase (nNOS) and endothelial nitric oxide synthase (eNOS) expressions, testosterone concentrations, neurogenic and endothelium-dependent relaxations of corpus cavernosum (CC), and circulating and cavernosal levels of inflammatory markers in aged rats. Animals were separated into control, aged, and etanercept-treated aged groups...

Penile erection is a neurovascular event and neurologic or vascular disturbances are major causes of erectile dysfunction (ED). Radical prostatectomy for prostate cancer not only induces cavernous nerve injury (CNI) but also results in cavernous angiopathy, which is responsible for poor responsiveness to oral phosphodiesterase-5 inhibitors. Dickkopf2 (DKK2) is known as a Wnt signaling antagonist and is reported to promote mature and stable blood vessel formation. Here, we demonstrated in CNI mice that overexpression of DKK2 by administering DKK2 protein or by using DKK2-Tg mice successfully restored erectile function: this recovery was accompanied by enhanced neural regeneration through the secretion of neurotrophic factors, and restoration of cavernous endothelial cell and pericyte content...

INTRODUCTION: To date, bilateral pelvic lymph node dissection (PLND) represents the most accurate and reliable staging procedure for the detection of lymph node invasion in prostate cancer and bladder cancer. However, the procedure is not devoid of complications. In this field, Indocyanine green fluorescence-guided sentinel lymph node (SLN) identification is an emerging and promising technique, as accurate staging of urologic cancer could be enhanced by a thorough evaluation of the sentinel lymph nodes...

Erectile dysfunction (ED), the most commonly reported sexual problem for men, reduces the quality of life for both patients and their partners. Even when physiologically effective, long-term adherence to ED treatments is poor. We review here the implication of having patients' partners involved in ED treatment, starting with treatment selection. We suggest that having partners engaged from the outset may promote an erotic association of the treatment with the partner, i.e., conceptually linking the aid to the sexual pleasure that the partner provides...

Over the past few decades, some principles in the treatment of penile cancer have changed fundamentally. While 15 years ago a negative surgical margin of at least 2 cm was considered mandatory, organ-sparing surgery permitting minimal negative surgical margins has a high priority nowadays. The current treatment principle requires as much organ preservation as possible and as much radicality as necessary. The implementation of organ-sparing and reconstructive surgical techniques has improved the quality of life of surviving patients...

INTRODUCTION: Transgender reassignment surgeries have become a major topic of interest within the last decade. Although there are numerous surgical techniques for male-to-female reassignment, a physician must assess each patient's anatomy and past medical history to determine the most suitable technique. Additionally, patient preference is important. The neovaginal constructive technique most commonly used in male-to-female reassignment surgery is penile skin inversion, but various other techniques and tissues can also be used including pelvic peritoneum, buccal mucosa, and bowel...

Eating a high fat laboratory chow enhances sensitivity of rats to the behavioral effects of drugs that act on dopamine systems (e.g., cocaine). Further, in male rats, eating high fat chow impairs expression of insulin signaling phosphorylated protein kinase B (pAkt), which is vital for maintaining dopamine homeostasis. Eating high fat chow enhances sensitivity of female rats to drugs that act indirectly on dopamine receptors (e.g., cocaine); however, less is known about sensitivity of females to drugs that act directly on dopamine receptors (e...

BACKGROUND: A small number of rhabdomyosarcoma (RMS) cases involve the bone marrow. A leukemic presentation of RMS has been reported in a few case series, although almost all cases of leukemic RMS are not completely mimicking leukemia. We encountered a case with RMS cell infiltration of the bone marrow that resembled floating hematological cells. CASE PRESENTATION: We encountered a rare case of a 15-year-old boy with a 2-week history of left femoral pain. Upon admission, he was afebrile with no other symptoms...

Genitalia are morphologically variable across many taxa and in physical contact during intromission, but little is known about how variation in form correlates with function during copulation. Marine mammals offer important insights into the evolutionary forces that act on genital morphology because they have diverse genitalia and are adapted to aquatic living and mating. Cetaceans have a fibroelastic penis and muscular vaginal folds, while pinnipeds have a baculum and lack vaginal folds. We examined copulatory fit in naturally deceased marine mammals to identify anatomical landmarks in contact during copulation and the potential depth of penile penetration into the vagina...

A 47-year-old man attended the emergency department following trauma during sexual intercourse after which he developed penile swelling and haematuria several hours later. A penile fracture was suspected but given the slightly atypical history, ultrasound was performed to look for a fracture. Given the history of haematuria, both a standard Doppler ultrasound and a microbubble-enhanced retrograde ultrasound urethrogram were performed. The Doppler confirmed the suspected diagnosis of penile fracture, and microbubble urethrogram demonstrated a urethral injury...

Rabbit corpus cavernosum smooth muscle (RCCSM) cells express ion channels that produce Ca(2+)-activated Cl(-) (IClCa) current, but low sensitivity to conventional antagonists has made its role in tone generation difficult to evaluate. We have reexamined this question using two new generation IClCa blockers, T16Ainh-A01 and CaCCinh-A01. Isolated RCCSM cells were studied using the perforated patch method. Current-voltage protocols revealed that both L-type Ca(2+) current and IClCa T16Ainh-A01 and CaCCinh-A01 (10 μM) reduced IClCa by ~85%, while 30 μM abolished it...
