Objective: To report a case of a mesothelioma of the tunica vaginalis and to review the published literature. Methods/Results: A 61-year-old patient complained of one-month increase of right scrotum size with pain. An ultrasound showed a right hydrocele with a mass attached to the tunica vaginalis. He didn't refer any urological history or known exposure to asbestos. Blood levels of tumor markers (alpha-fetoprotein and beta-HCG) were within normal limits. We performed a radical inguinal orchiectomy with an en-bloc resection of the tunica vaginalis. The pathology described a potentially malignant biphasic mesothelioma. The patient has remained asymptomatic with negative extension studies after 10 years of follow up. Conclusions: Paratesticular mesotheliomas are rare tumors (approximately 250 cases reported) with uncertain etiology (only 30-40% are associated with asbestos exposure). The age range is between 50-70 years. Its presentation is usually as a scrotal mass with recurrent reactive hydrocele, which may delay early diagnosis. During surgery, intraoperative biopsy is recommended. It is important to do a differential diagnosis with other benign diseases. Treatment is only curative in early stages with radical orchidectomy and resection in-block of the tunica vaginalis. Despite being multidisciplinary, it is not curative in most cases due to rapid local and distant spread.

Introduction. Preservation of sexual function after surgery represents a major issue for patients undergoing radical prostatectomy (RP). Aim. To investigate determinants of patients' desire to preserve sexual activity before RP and surgeons' final decision to perform a nerve-sparing RP (NSRP). Methods. Overall, 2,408 prostate cancer patients, candidates to RP, from 136 urologic departments across the Italian territory were evaluated in a multicenter prospective observational study. All patients underwent RP, according to single-center indications and procedures. Main Outcome Measures. Age, body mass index, previous benign prostatic hyperplasia history, preoperative tumor characteristics, quality of life through the Short Form Health Survey (SF-12), and the University of California Los Angeles Prostate Cancer Index (UCLA-PCI), erectile function through the International Index of Erectile Function (IIEF-5), desire to preserve sexual activity, NS operative outcomes, and surgical margins status were recorded. Results. Overall, 1,667 were interested to preserve sexual activity. Age, physical component summary of SF12 (PCS-12), sexual function score of UCLA-PCI, and IIEF-5 score were the main determinants of such interest. Only 1,246 patients were suitable for a NSRP according to guidelines. Surgeons performed a non-NSRP (NNSRP) in 1,234 patients, a unilateral NSRP in 318 and a bilateral NSRP in 856. Age, bioptical Gleason score, percentage of positive cores, PCS-12, and patient's desire to preserve sexual activity were the main determinants of final decision for a NSRP. Surgeons performed a NSRP in 424 not suitable and in 121 not interested patients. Positive surgical margins in not suitable patients submitted to NSRP were not higher if compared to that obtained after NNSRP in the same subgroup. Limits include lack of oncological and functional follow-up. Conclusions. Most patients are interested to preserve sexual activity. Discrepancies exist among patients' preferences, guidelines' indications, and surgeon's final decision. © 2011 International Society for Sexual Medicine.

IMPORTANCE: The use of androgen deprivation therapy (ADT) in the treatment of advanced prostate cancer has been shown to delay the clinical progression of the disease. However, the testosterone suppression associated with this therapymay lead to a hypogonadal condition that can have detrimental effects on renal function, thus raising the hypothesis that ADT-induced hypogonadism could potentially lead to acute kidney injury (AKI). OBJECTIVE: To determine whether the use of ADT is associated with an increased risk of AKI in patients newly diagnosed with prostate cancer. DESIGN AND SETTING: A nested case-control analysis using medical information extracted from the UK Clinical Practice Research Datalink linked to the Hospital Episodes Statistics database. PARTICIPANTS: Men newly diagnosed with nonmetastatic prostate cancer between January 1, 1997, and December 31, 2008, were selected and followed up until December 31, 2009. Cases were patients with incident AKI during follow-up who were randomly matched with up to 20 controls on age, calendar year of prostate cancer diagnosis, and duration of follow-up. MAIN OUTCOMES AND MEASURES: Conditional logistic regressionwas used to estimate odds ratios (ORs) with 95%CIs of AKI associated with the use of ADT. ADT was categorized into 1 of 6 mutually exclusive groups: gonadotropin-releasing hormone agonists, oral antiandrogens, combined androgen blockade, bilateral orchiectomy, estrogens, and combination of the above. RESULTS: A total of 10 250 patients met the study inclusion criteria. During a mean follow-up of 4.1 (SD, 2.9) years, 232 incident cases of AKI were identified (rate, 5.5/1000 person-years). Overall, current use of any ADT was associated with an increased risk of AKI when compared with never use (OR, 2.48 [95%CI, 1.61-3.82]), generating a rate difference of 4.43/1000 persons per year (95%CI, 1.54-7.33). This association was mainly driven by a combined androgen blockade consisting of gonadotropin-releasing hormone agonists with oral antiandrogens (OR, 4.50 [95%CI, 2.61-7.78]), estrogens (OR, 4.00 [95%CI, 1.06-15.03]), other combination therapies (OR, 4.04 [95%CI, 1.88-8.69]), and gonadotropin-releasing hormone agonists (OR, 1.93 [95%CI, 1.20-3.10]). CONCLUSIONS AND RELEVANCE: In a cohort of patients with newly diagnosed nonmetastatic prostate cancer, the use of ADT was significantly associated with an increased risk of AKI. These findings require replication in other well-designed studies as well as further investigation of their clinical importance.

Cervical cancer, the second leading cause of cancer mortality in women worldwide, results from infection with a subset of human papillomaviruses (HPV), HPV-16 being the most prevalent type. The available prophylactic vaccines are an effective strategy to prevent this cancer in the long term. However, they only target 70-80% of all cervical cancers and cannot control existing HPV infections and associated lesions. Therapeutic vaccines are thus necessary for women who cannot benefit from prophylactic vaccination. Induction of protective immune responses in the genital mucosa (GM) may be crucial for efficacy of HPV therapeutic vaccines. We report here that mice that received a single subcutaneous (s.c.) vaccination of an adjuvanted long synthetic HPV16 E7 1-98 polypeptide showed induction of 100% tumor protection against s.c. TC-1 tumors and that tumor regression was mainly provided by CD8 T cells. In vivo cytotoxic assay revealed high E7-specific cytolytic T lymphocytes activity in spleen and in genital draining lymph nodes (LN), and E7-specific CD8 T cells could be detected in GM by tetramer staining. More importantly, high-avidity E7-specific INF-γ secreting CD8 T cells were induced not only in blood, spleen and LN but also in GM of vaccinated mice, thus providing evidence that a parenteral vaccination may be sufficient to provide regression of genital tumors. In addition, there was no correlation between the responses measured in blood with those measured in GM, highlighting the necessity and relevance to determine the immune responses in the mucosa where HPV-tumors reside. © 2009 UICC.

Purpose: To determine the safety of continued administration of antithrombotic agents during transperineal (TP) prostate biopsy. Patients and Methods: A total of 811 men who underwent transrectal ultrasound (TRUS)-guided TP biopsy from January 2008 to June 2012 at our two institutions were retrospectively analyzed. Among these 811 men, 672 received no antithrombotic agents (group I), 103 received and continued administration of antithrombotic agents (group II), and 36 interrupted administration of antithrombotic agents (group III). Overall complications were graded and hemorrhagic complications were compared (group I with group II) using propensity score matching (PSM) analysis. Results: An overall complication rate of 4.6% was recorded. Hemorrhagic complications occurred in 1.8% and they were virtually identical in all the three groups, and no severe hemorrhagic complications occurred. One patient in group III required intensive care unit admission for cerebral infarction. PSM analysis revealed no statistical difference between groups I and II with regard to the incidence of gross hematuria, perineal hematoma, and rectal bleeding. Multiple regression analysis revealed that hemorrhagic complications were associated with lower body mass index (<21 kg/m2, P=0.0058), but not with administration of antithrombotic agents. Conclusions: Continued administration of antithrombotic agents does not increase the risk of hemorrhagic complications; these agents are well tolerated during TP biopsy.
