Remodeling of the Cardiac Extracellular Matrix Proteome During Chronological and Pathological Aging.

Impaired extracellular matrix (ECM) remodeling is a hallmark of many chronic inflammatory disorders that can lead to cellular dysfunction, aging, and disease progression. The ECM of the aged heart and its effects on cardiac cells during chronological and pathological aging are poorly understood across species. For this purpose, we first used mass spectrometry-based proteomics to quantitatively characterize age-related remodeling of the left ventricle (LV) of mice and humans during chronological and pathological (Hutchinson-Gilford progeria syndrome (HGPS)) aging. Of the approximately 300 ECM and ECM-associated proteins quantified (named as Matrisome), we identified 13 proteins that were increased during aging, including lactadherin (MFGE8), collagen VI α6 (COL6A6), vitronectin (VTN) and immunoglobulin heavy constant mu (IGHM), whereas fibulin-5 (FBLN5) was decreased in most of the data sets analyzed. We show that lactadherin accumulates with age in large cardiac blood vessels and when immobilized, triggers phosphorylation of several phosphosites of GSK3B, MAPK isoforms 1, 3, and 14, and MTOR kinases in aortic endothelial cells (ECs). In addition, immobilized lactadherin increased the expression of pro-inflammatory markers associated with an aging phenotype. These results extend our knowledge of the LV proteome remodeling induced by chronological and pathological aging in different species (mouse and human). The lactadherin-triggered changes in the proteome and phosphoproteome of ECs suggest a straight link between ECM component remodeling and the aging process of ECs, which may provide an additional layer to prevent cardiac aging.

Vascular closure devices in living-donor nephrectomy: a much-needed systematic review and meta-analysis focusing on safety.

OBJECTIVE: To assess the safety of vascular closure devices in living-donor nephrectomy (LDN), as staplers and non-transfixion techniques (polymer locking and metal clips) are the methods employed to secure the renal vessels during laparoscopic and robotic LDN, but the use of clips has come into question since the United States Food and Drug Administration and manufacturers issued a contraindication. METHODS: A systematic review and meta-analysis were conducted to assess the safety of vascular closure devices (International Prospective Register of Systematic Reviews [PROSPERO] registration: CRD42022364349). The PubMed, Scopus, the Excerpta Medica dataBASE (EMBASE), and the Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) databases were searched in September 2022. For comparative and non-comparative studies, incidence estimates and odds ratios (ORs), respectively, for the main variables regarding safety of vascular closure devices were pooled by using random effects meta-analyses. Quality assessment of the included comparative studies was conducted using the Risk Of Bias In Non-randomised Studies of Interventions (ROBINS-I) tool. RESULTS: Of the 863 articles obtained, data were retrieved from 44 studies, which included 42 902 patients. In non-comparative studies, the pooled estimate rates for device failure, severe haemorrhage rate, conversion to open surgery, and mortality were similar for both clips and staplers. Regarding the meta-analyses for comparative studies (three studies), there were no significant differences between the two groups for the severe haemorrhage rate (OR 0.57, 95% confidence interval [CI] 0.18-1.75; P = 0.33), conversion to open surgery (OR 0.35, 95% CI 0.08-1.54; P = 0.16), or death rate (OR 3.64, 95% CI 0.47-28.45; P = 0.22). Based on weak evidence, device failure was lower in the polymer clip group (OR 0.41, 95% CI 0.23-0.75; P = 0.00). CONCLUSIONS: This study has confirmed that there is no evidence for the superiority of any vascular closure device in terms of safety in LDN. Standardised recommendations for vascular control in this context should be carefully designed and prospectively evaluated.

Anti-Algics in the Therapeutic Response of Breast and Urological Cancers.

The effect of anti-algics on tumor progression and the overall survival of patients is controversial and remains unclear. Herein, we disclose the in vitro effects of the local anesthetics lidocaine, ropivacaine, and levobupivacaine on breast (MCF7), prostate (PC3, LNCaP), and bladder (TCCSUP, HT1376) cancer cell lines, both as monotherapy and in combination with standard-of-care therapeutics. Assays for cell proliferation, viability, death profile, and migration were performed. Additionally, we explored the clinical outcomes of opioid use through a cross-sectional study involving 200 metastatic prostate cancer patients. The main clinical data collected included the type of opioid therapy administered, dosage, treatment duration, disease progression, and overall survival. Results obtained demonstrate that treatment with local anesthetics has a promising selective anti-tumor effect on these types of cancer, with higher effects when associated with docetaxel. This points out the use of local anesthetics as an added value in the treatment of prostate carcinoma patients. Alternatively, chronic opioid use was correlated with reduced overall survival (p < 0.05) and progression-free survival (p < 0.05) at each treatment line in the observational study. While these results provide valuable insights, larger prospective studies are imperative to comprehensively evaluate the clinical impact of opioid analgesics in prostate cancer patients.

The type of SARS-CoV-2 vaccine influences serological response in kidney transplant recipients.

Vaccination is a promising strategy to control the ongoing pandemic; however, solid organ recipients tend to develop a weaker immune response to vaccination. Anti-spike SARS-CoV-2 antibodies titers were measured 2-4 weeks post-vaccination completion in 131 KT patients without previous infection. Demographic, clinical, and laboratorial parameters were analyzed to identify which factors contributed to seroconversion. Factors that influenced seroconversion, that occurred in 76 patients (58%), were longer time post-transplant, immunosuppression without an antiproliferative drug and vaccination with mRNA vaccines. Patients who received mRNA vaccines had significantly higher rates of seroconversion compared with adenovirus vector vaccines (67% vs 33%, P < .001) and higher anti-spike IgG titers. These findings reinforce the need to discuss the vaccination strategy in this population, including a third dose with a mRNA vaccine.

Oxidative stress in bladder cancer: an ally or an enemy?

Bladder cancer (BC) is the most common cancer of the urinary tract and despite all innovations, remains a major challenge due to high morbidity and mortality. Genomic and epigenetic analyses allowed the discovery of new genes and pathways involved in the pathogenesis and regulation of BC. However, the effect on mortality has been modest and the development of new targets for BC treatment are needed. Recent evidence suggests that cancer cells are under increased stress associated with oncogenic transformation, with changes in metabolic activity and increased generation of reactive oxygen species (ROS). The increased amounts of ROS in cancer cells are associated with stimulation of cellular proliferation, promotion of mutations and genetic instability, as well as alterations in cellular sensitivity to anticancer agents. Since these mechanisms occur in cancer cells, there is a close link between oxidative stress (OS) and BC with implications in prevention, carcinogenesis, prognosis, and treatment. We address the role of OS as an enemy towards BC development, as well as an ally to fight against BC. This review promises to expand our treatment options for BC with OS-based therapies and launches this approach as an opportunity to improve our ability to select patients most likely to respond to personalized therapy.

Renal Procurement: Techniques for Optimizing the Quality of the Graft in the Cadaveric Setting.

PURPOSE OF REVIEW: Kidney transplantation is the best treatment for end-stage renal disease. However, due to organ shortage, suboptimal grafts are increasingly being used. RECENT FINDINGS: We carried out a review on the methods and techniques of organ optimization in the cadaveric setting. Donor care is the first link in a chain of care. Right after brain death, there is a set of changes, of which hormonal and hemodynamic changes are the most relevant. Several studies have been conducted to determine which drugs to administer, although in most cases, the results are not definitive. The main goal seems rather achieve a set of biochemical and hemodynamic objectives. The ischemia-reperfusion injury is a critical factor for kidney damage in transplantation. One of the ways found to deal with this type of injury is preconditioning. Local and remote ischemic preconditioning has been studied for various organs, but studies on the kidney are scarce. A new promising area is pharmacological preconditioning, which is taking its first steps. Main surgical techniques were established in the late twentieth century. Some minor new features have been introduced to deal with anatomical variations or the emergence of donation after circulatory death. Finally, after harvesting, it is necessary to ensure the best conditions for the kidneys until the time of transplantation. Much has evolved since static cold preservation, but the best preservation conditions are yet to be determined. Conservation in the cold has come to be questioned, and great results have appeared at temperatures closer to physiological.

Combined genetic and epigenetic alterations of the TERT promoter affect clinical and biological behavior of bladder cancer.

In urothelial bladder cancer (UBC), risk stratification remains an important unmet need. Limitless self-renewal, governed by TERT expression and telomerase activation, is crucial for cancer progression. Thus, telomerase activation through the interplay of mutations (TERTpMut ) and epigenetic alterations in the TERT promoter may provide further insight into UBC behavior. Here, we investigated the combined effect of TERTpMut and the TERT Hypermethylated Oncological Region (THOR) status on telomerase activation and patient outcome in a UBC international cohort (n = 237). We verified that TERTpMut were frequent (76.8%) and present in all stages and grades of UBC. Hypermethylation of THOR was associated with higher TERT expression and higher-risk disease in nonmuscle invasive bladder cancers (NMIBC). TERTpMut alone predicted disease recurrence (HR: 3.18, 95%CI 1.84 to 5.51, p < 0.0001) but not progression in NMIBC. Combined THORhigh /TERTpMut increased the risk of disease recurrence (HR 5.12, p < 0.0001) and progression (HR 3.92, p = 0.025). Increased THOR hypermethylation doubled the risk of stage progression of both TERTpwt and TERTpMut NMIBC. These results highlight that both mechanisms are common and coexist in bladder cancer and while TERTpMut is an early event in bladder carcinogenesis THOR hypermethylation is a dynamic process that contributes to disease progression. While the absence of alterations comprises an extremely indolent phenotype, the combined genetic and epigenetic alterations of TERT bring additional prognostic value in NMIBC and provide a novel insight into telomere biology in cancer.

Serum miRNA Predicts Viable Disease after Chemotherapy in Patients with Testicular Nonseminoma Germ Cell Tumor.

PURPOSE: Retroperitoneal lymph node dissection is recommended for residual masses greater than 1 cm after chemotherapy of nonseminomatous germ cell tumors. Currently there is no reliable predictor of post-chemotherapy retroperitoneal lymph node dissection histology. Up to 50% of patients harbor necrosis/fibrosis only so that a potentially morbid surgery has limited therapeutic value. In this study we evaluated the ability of defined serum miRNAs to predict residual viable nonseminomatous germ cell tumors after chemotherapy. MATERIALS AND METHODS: Levels of serum miRNA, including miR-371a-3p, miR-373-3p and miR-367-3p, were measured using the ampTSmiR (amplification targeted serum miRNA) test in 82 patients, including 39 in cohort 1 and 43 in cohort 2, who were treated with orchiectomy, chemotherapy and post-chemotherapy retroperitoneal lymph node dissection. miRNA levels were compared to clinical characteristics and serum tumor markers, and correlated with the presence of viable germ cell tumor vs fibrosis/necrosis and teratoma. ROC analysis was done to determine miRNA discriminative capacity. RESULTS: miRNA levels were significantly associated with disease extent at chemotherapy and they decreased significantly after chemotherapy. Conventional serum tumor marker levels were uninformative after chemotherapy. However, after chemotherapy miRNA levels remained elevated in patients harboring viable germ cell tumor in post-chemotherapy retroperitoneal lymph node dissection specimens. miR-371a-3p demonstrated the highest discriminative capacity for viable germ cell tumors (AUC 0.874, 95% CI 0.774-0.974, p <0.0001). Using an adapted hypothetical cutoff of 3 cm or less for surgical intervention miR-371a-3p correctly stratified all patients with viable residual retroperitoneal germ cell tumors with 100% sensitivity (p = 0.02). CONCLUSIONS: Our study demonstrates for the first time the potential value of miR-371a-3p to predict viable germ cell tumors in residual masses after chemotherapy. Prospective studies are required to confirm clinical usefulness.

Mechanisms of human telomerase reverse transcriptase (hTERT) regulation: clinical impacts in cancer.

BACKGROUND: Limitless self-renewal is one of the hallmarks of cancer and is attained by telomere maintenance, essentially through telomerase (hTERT) activation. Transcriptional regulation of hTERT is believed to play a major role in telomerase activation in human cancers. MAIN BODY: The dominant interest in telomerase results from its role in cancer. The role of telomeres and telomere maintenance mechanisms is well established as a major driving force in generating chromosomal and genomic instability. Cancer cells have acquired the ability to overcome their fate of senescence via telomere length maintenance mechanisms, mainly by telomerase activation. hTERT expression is up-regulated in tumors via multiple genetic and epigenetic mechanisms including hTERT amplifications, hTERT structural variants, hTERT promoter mutations and epigenetic modifications through hTERT promoter methylation. Genetic (hTERT promoter mutations) and epigenetic (hTERT promoter methylation and miRNAs) events were shown to have clinical implications in cancers that depend on hTERT activation. Knowing that telomeres are crucial for cellular self-renewal, the mechanisms responsible for telomere maintenance have a crucial role in cancer diseases and might be important oncological biomarkers. Thus, rather than quantifying TERT expression and its correlation with telomerase activation, the discovery and the assessment of the mechanisms responsible for TERT upregulation offers important information that may be used for diagnosis, prognosis, and treatment monitoring in oncology. Furthermore, a better understanding of these mechanisms may promote their translation into effective targeted cancer therapies. CONCLUSION: Herein, we reviewed the underlying mechanisms of hTERT regulation, their role in oncogenesis, and the potential clinical applications in telomerase-dependent cancers.

Prognostic value of subclassification (pT2 stage) of pathologically organ-confined prostate cancer: Confirmation of the changes introduced in the 8th edition of the American Joint Committee on Cancer (AJCC) staging system.

OBJECTIVE: The last edition of the AJCC staging system eliminated the pT2 subclassification of prostate cancer (PCa). Our objective was to evaluate the association of pT2 subclassification with the oncological results of patients with PCa who underwent radical prostatectomy (RP). MATERIAL AND METHODS: We evaluated 367 patients who underwent RP between 2009 and 2016, with pT2 disease in the final pathological evaluation. We assessed differences in rates of biochemical recurrence (BCR), metastasis and mortality between T2 substages (pT2a/b vs pT2c). RESULTS: Fifty-three (14.4%) patients presented pT2a/b disease and 314 (85.6%) pT2c disease. The mean follow-up time was 4.9 ± 2.6 years. Grade group scores (p = 0.1) and prostate specific antigen (PSA) (p = 0.2) did not differed between pT2 substages. The rate of BCR in pT2a/b and pT2c patients was 11.3% and 18.2%, respectively (p = 0.2). Five (9.4%) patients with pT2a/b and 45 (14.3%) with pT2c substage underwent salvage radiotherapy (p = 0.3). The rate of positive surgical margins did not differ between groups (p = 0.2). Seven (2.2%) patients with pT2c had lymph nodes or distant metastases. The overall survival was 92.5% and 93.6% in pT2a/b and pT2c, respectively (p = 0.2). CONCLUSION: Our results are in accordance with the changes introduced in the 8th edition of the AJCC staging system in which the pT2 subclassification was eliminated.

Diabetes mellitus and prostate cancer metabolism: Is there a relationship?

OBJECTIVE: Our aim was to evaluate the effects of glucose levels and diabetes mellitus in prostate cancer (PCa) biology. MATERIALS AND METHODS: Two PCa cell lines (LNCap and PC3) were cultured in RPMI medium with different glucose concentrations [5mM (LG) and 25mM (HG)]. Expressions of androgen receptor, Her2/neu and glucose transporters (GLUT1, 3, 5 and 12) were evaluated by flow cytometry. Proliferation rate was assessed by colorimetric assay MTT and cellular characterization was performed by haematoxylin and eosin staining. Additionally, we performed a cross sectional analysis of 704 patients undergoing radical prostatectomy who were divided into two groups (diabetic and non-diabetic). An analysis of clinical and histological data seeking to identify the differences on tumor aggressiveness between the two groups was performed. RESULTS: In LNCaP cell line, when the glucose concentration in the medium increased, there was an increased in AR expression. Regarding expression of Her2/neu receptor, medium's glucose concentration significantly changed the expression of this receptor in both PC3 and LNCaP cell lines. Growth rate was higher on the HG medium for both cell lines. The clinical study of patients undergoing radical prostatectomy revealed no relationship between the presence of diabetes and the development of more aggressive tumours. Diabetic patients had significantly higher prostatic volumes, however, no significant difference was found between the relapse risk classification or the ISUP classification between the two groups. CONCLUSIONS: Our results showed that medium glucose concentration could influence prostate cancer cells growing but not the aggressiveness.

Cancer Stem Cells in Prostate Cancer: Implications for Targeted Therapy.

Prostate cancer (PCa) is the most frequently diagnosed cancer in men and the second most common cause of cancer-related mortality among men in the developed world. Conventional anti-PCa therapies include surgery, radiation, hormonal ablation, and chemotherapy. Despite increasing efforts, these therapies are not effective for patients with advanced and/or metastatic disease. In most cases, cancer therapies fail due to an incomplete depletion of tumor cells, resulting in tumor relapse. The cancer stem cell (CSC) hypothesis is an emerging model that explains many of the molecular characteristics of oncological disease as well as the tendency of cancers to relapse, metastasize, and develop resistance to conventional therapies. CSCs are a reservoir of cancer cells that exhibit properties of self-renewal and the ability to reestablish the heterogeneous tumor cell population. The existence of PCa stem cells offers a theoretical explanation for many uncertainties regarding PCa and also for treatment resistance and disease progression once clinical cure is achieved. Therapies targeting CSCs might therefore lead to more effective cancer treatments, divergent from a traditional anti-proliferative approach, based on tumor bulk reduction accompanied by CSC-specific inhibition. Here, we focus on reviewing the historical perspective as well as concepts regarding stem cells and CSCs in PCa. In addition, we will report possible strategies and new clinical approaches that address the CSC-based concept of tumorigenesis in PCa.

Is lower urinary tract dysfunction an early marker of Portuguese type familial amyloidotic polyneuropathy in women? Preliminary results.

Type 1 Portuguese Familial Amyloid Polyneuropathy was first observed in 1939 and described in 1951 by Corino Andrade. FAP is a rare autosomal dominant disease caused by a mutant gene in chromosome 18, characterized by a variant transthyretin in which valine is substituted for methionine at position 30 (ATTR V30M), affecting mainly young adults. ATTR V30M positivity does not imply disease, but the disease is only present with ATTR V30M in serum. The clinical manifestations of FAP on the pelvic floor and genitourinary system are frequent at early disease onset. Phenotypic diversity can depend on modulating agents in the deposition of the mutant TTR, such as incomplete penetration and environmental influence. Functional vesicourethral disorders appear to be primarily at the bladder filling phase, namely diminished bladder sensation, and associated with a decrease in detrusor contractility during the emptying phase. Unbalanced voiding takes place in this context, with high post-void residuals, increasing the rate of co-morbidity, namely recurrent urinary tract infections and chronic renal failure.This study describes the lower urinary tract dysfunctions in ATTR V30M positive carriers, particularly during the asymptomatic period and early stages of the disease, and additionaly it describes its association with the clinical evolution of the disease. In the preliminary phase of the study, the lower urinary tract dysfunction in FAP-women may present itself as an early manifestation in asymptomatic patients. Uroflowmetry and the evaluation of post-voiding residual volume are non-invasive and low cost tests that should be done during routine initial evaluation. Reduced bladder sensation and poor detrusor contractility may be considered initial markers of FAP. The neurogenic factor (bladder afferent neurons) appears to be mechanical in nature with myogenic repercussions. This further aggravates the bladder underactivity secondary to pelvic efferent parasympathetic neuropathy and amyloid infiltration in the bladder wall. Early diagnostic and therapeutic intervention may avoid secondary end stage renal disease.

The Kidney Transplant Lottery: A Highly Sensitized Patient, Without Mismatches and Vein Thrombosis of the Graft; A Case Report.

A kidney transplant is the best option for patients with end-stage renal disease. The waiting list period can be long, especially for highly sensitized patients. We describe a 60-year-old woman who received a second transplant and was highly sensitized to vascular access exhaustion, anuric, and performing peritoneal dialysis. At 27 days post-transplant, the patient developed thrombosis of the allograft vein, oliguria, and elevated serum creatinine. Fibrinolysis was attempted, but the patient remained oliguric and with acute graft dysfunction. She had a suction thrombectomy using the Penumbra System, allowing the removal of all thrombi and repermeabilization of the vein graft, resolving the acute graft dysfunction.

Immunotherapy-induced adverse events in metastatic renal cell carcinoma: A case of rapid response and complex challenges.

A 55-year-old woman with dyspnea was diagnosed with a 9.5cm left renal clear cell carcinoma and extensive metastatic disease. Initial treatment with Sunitinib was effective but discontinued due to severe dermatitis. Nivolumab therapy led to complete metastasis resolution and consequently nephrectomy was performed at 12 months. Postoperatively, she developed Vogt-Koyanagi-Harada-like disease, necessitating Nivolumab suspension and vision improvement with corticosteroids. After 24 disease-free months, a new contralateral renal lesion and pulmonary metastases were identified, prompting cabozantinib treatment. This resulted in clinical improvement and a partial response at the first follow-up.

Training of European urology residents in laparoscopy: results of a pan-European survey.

OBJECTIVE: To assess the participation of European urology residents in urological laparoscopy, their training patterns and facilities available in European Urology Departments. MATERIALS AND METHODS: A survey, consisting of 23 questions concerning laparoscopic training, was published online as well as distributed on paper, during the Annual European Association of Urology Congress in 2012. Exposure to laparoscopic procedures, acquired laparoscopic experience, training patterns, training facilities and motivation were evaluated. Data was analysed with descriptive statistics. RESULTS: In all, 219 European urology residents answered the survey. Conventional laparoscopy was available in 74% of the respondents' departments, while robotic surgery was available in 17% of the departments. Of the respondents, 27% were first surgeons and 43% were assistants in conventional laparoscopic procedures. Only 23% of the residents rated their laparoscopic experience as at least 'satisfactory'; 32% of the residents did not attend any course or fellowship on laparoscopy. Dry laboratory was the most frequent setting for training (33%), although 42% of the respondents did not have access to any type of laparoscopic laboratory. The motivation to perform laparoscopy was rated as 'high' or 'very high' by 77% of the respondents, and 81% considered a post-residency fellowship in laparoscopy. CONCLUSIONS: Urological laparoscopy is available in most European training institutions, with residents playing an active role in the procedure. However, most of them consider their laparoscopic experience to be poor. Moreover, the availability of training facilities and participation in laparoscopy courses and fellowships are low and should be encouraged.

An unusual cause of acute cardiogenic shock in the operating room.

A 51-year-old man with a renal carcinoma with inferior vena cava (IVC) invasion was referred to our hospital for the performance of a radical nephrectomy with IVC thrombus excision. To prevent embolism, an IVC filter was implanted the day before surgery below the suprahepatic veins. On nephrectomy completion, the clinical status of the patient started to deteriorate and an unsuccessful attempt was made to excise the IVC thrombus. The patient developed profound refractory hypotension without significant bleeding and worsening splanchnic stasis was noted. A transesophageal echocardiogram was immediately performed in the operating room, revealing a hemispheric mass protruding from the IVC ostium to the right atrium, completely blocking all venous return. Volume depletion was evident by low left and right atrial volumes and increased septum mobility. No other abnormalities were found that could explain the shock, namely ventricular dysfunction or valvular disease. Cardiac surgery consultation was immediately obtained, ultimately deciding to perform a median sternotomy with direct exploration of right atrium. Under cardiopulmonary bypass, a 6-cm long thrombotic mass was identified, involving the IVC filter, blocking all lower body venous return; the removal of the mass reversed the shock. The patient had an uneventful recovery. Adverse outcomes associated with IVC filters are common. Our case highlights the importance of a team approach to rapid changes in hemodynamic status in the operating room, including the surgeon, the anesthesiologist, and the cardiologist. It also emphasizes the pivotal role of transesophageal echocardiogram in the clinical evaluation of severely unstable patients.

Seminal human papillomavirus infection: a narrative review.

BACKGROUND: Human papillomavirus (HPV) infection is one of the most prevalent sexually transmitted infections that can lead to malignant pathologies as well as fertility problems. The aim of this study was to evaluate the prevalence of HPV infection in males, its impact on semen parameters, and reproductive consequences. We also evaluated potential measures that could prevent negative outcomes of HPV infection in males. METHODS: A systematic literature search using PubMed/Medline and Embase databases was performed to search for English articles published until July 2023. We explored three different aspects: (1) prevalence of HPV semen infection and its impact on seminal parameters; (2) the relationship between HPV semen infection and infertility risk and reproductive outcomes; and (3) potential measures that could prevent the negative outcomes related to HPV seminal infection. The identified studies were first screened and assessed independently by one author, and then validated by two additional authors. Data were extracted from 19 studies. RESULTS: The prevalence of seminal HPV infection was higher among infertile males. In addition to controversies about the real interference of seminal HPV infection on sperm parameters, a growing number of studies have demonstrated a correlation between unexplained infertility and seminal HPV infection. Semen HPV infection is also associated with lower rates of pregnancy and higher rates of miscarriage. Prevention measures such as HPV vaccination seem promising. CONCLUSION: Further studies are required to confirm not only the association between HPV infection and reproductive outcomes but also the benefit of preventive measures.

Septic Shock After Intravesical Therapy With Bacillus Calmette-Guerin: A Case Report of a Rare Life-Threatening Complication.

Intravesical therapy with Bacillus Calmette-Guerin (BCG) is the mainstay treatment for high-risk non-muscle invasive bladder cancer. The side effects are usually local and mild. Systemic dissemination of BCG is rare, typically develops soon after instillation, and may present as a severe life-threatening condition. We present a case of a 49-year-old man under chronic haemodialysis who developed septic shock after the first BCG maintenance instillation for bladder carcinoma in situ (CIS). Supportive measures and empiric broad-spectrum antibiotic therapy were promptly started after sample collection for cultures. Lastly, the recurrence of fever raised the initial suspicion of BCG dissemination. The diagnosis was confirmed by the identification of the Mycobacterium tuberculosis complex in blood samples collected and anti-tuberculosis therapy was then initiated. We would like to highlight the need for early recognition of a systemic BCG infection and the importance of starting anti-tuberculosis treatment as early as possible.

A penile fracture hidden behind a urethral bleeding.

Penile fracture with urethral injury is uncommon. Diagnosis is usually based on clinical history and physical examination. Nonetheless, atypical presentation obliges complementary examinations to be performed. We report a case of a 45-years-old man with urethral bleeding after a blunt penile trauma that was ultimately diagnosed as having a cavernous body laceration on top of an urethral rupture.
