Comparative Study
A Comparison of Outcomes from Antibiotic Treatment with and without Probiotics in 897 Patients with Lower Urogenital Tract Infections, Including Cystitis, Urethritis, Prostatitis, and Vulvovaginitis.
BACKGROUND Urogenital bacterial infections have a high incidence in humans. The most frequent cause of infections of the urogenital tract is gram-negative bacteria. Antibiotics are very effective in curing infectious diseases but they are accompanied by health complications. Probiotics are live microorganisms that are believed to confer a beneficial effect on human health when consumed in adequate amounts. This study aimed to compare outcomes from antibiotic treatment with and without the use of probiotics in 897 patients with lower urogenital tract infections, including cystitis, urethritis, prostatitis, and vulvovaginitis. MATERIAL AND METHODS A total of 897 patients aged 18 to 55 years were included in this research. Patients were divided into an intervention group including 460 patients (254 women, 206 men) and a comparison group including 437 patients (240 women, 197 men). The probiotics received by patients were capsules of ProBalans®. The diagnosis of cystitis, urethritis, prostatitis, vulvovaginitis, and sexually transmitted infection was done using several tests, and antibiotics were used for treatment. Qualitative data were analyzed using the chi-square or Fisher exact test. RESULTS We found a significant difference regarding patients' impressions of improvement after therapy between patients in the intervention group and the comparison group. CONCLUSIONS Use of probiotics together with antibiotics in the treatment of urogenital tract infection can help to reduce the adverse effects of antibiotics, increase the efficiency of antibiotic therapy, and reduce bacterial resistance to antibiotics. However, further research is needed to confirm these potential health benefits.

Frontiers in Endocrinology 2024This study aims to investigate the impacts of phimosis on the health of the genitourinary system through Mendelian random analysis.
PURPOSE
This study aims to investigate the impacts of phimosis on the health of the genitourinary system through Mendelian random analysis.
MATERIAL AND METHOD
A dual-sample Mendelian randomization (MR) analysis was conducted using the publicly available genome-wide association study (GWAS) data. The inverse variance weighted based on the random effects model (Re-IVW) method was used as the main statistical analysis. Complementary methods, including weighted median, MR-Egger regression, and MR pleiotropy residual sum and outlier (MR-PRESSO), were applied to detect or correct the impact of horizontal pleiotropy.
RESULT
Re-IVW showed a genetic predictive causal relationship of phimosis on glomerulonephritis (odds ratio [OR]: 1.37 [1.13-1.65], = 0.00149) and IgA glomerulonephritis (OR: 1.57 [1.18-2.09), = 0.00187). Suggestive evidence indicated that phimosis was associated with chronic nephritis syndrome (OR: 1.23 (1.00-1.51), p = 0.0481], acute nephritis syndrome (OR: 1.50 [1.13-2.01], = 0.0058), and impotence (OR: 1.39 [1.11-1.73], = 0.0035). Kidney and ureteral stone (OR: 1.14 [1.04-1.26], = 0.0069), urethral strictures (OR: 1.26 [1.07-1.48], = 0.0050), benign prostatic hyperplasia (OR: 1.07 [1.01-1.13], = 0.0242), and decreased testicular function (OR: 0.72 [0.56-0.94], = 0.0141) have genetically predictive causal relationships.
CONCLUSION
In summary, we employed a series of reliable analytical methods to investigate the association between phimosis and 26 urogenital diseases. We have reported several strong associations, but more research is needed to evaluate whether this discovery is replicated in other environments and to gain a better understanding of potential mechanisms.

Prostate cancer is the second most common cancer in men across the world. Prior to PSA testing, men usually presented with locally advanced disease detected on digital rectal exam or with metastatic disease. PSA ushered in the era of serum biomarkers for prostate cancer. It has taken over three decades to refine the role of PSA in prostate cancer detection. The lack of specificity has spurred research into finding better, readily obtainable biomarkers with high sensitivity and specificity. The trick is to find the prostate cancers that are a threat, not the ones that aren't. Over the last decade and more, many biomarkers have been proposed and tested (HK-2, Pro-PSA, PCA3, TMPRSS2:ERG fusion transcripts, miRNA, just to name a few) but we still await that magical combination of a readily available, reproducible, and hopefully inexpensive biomarker with high sensitivity and specificity. The authors describe the use of a peptide labeled fluorophore for the VPAC1 receptors that are expressed on malignant prostate cancer cells shed in the urine. After initial feasibility work, the authors collected urine from 318 men with lower urinary tract symptoms and a PSA > 4. The patients underwent prostate biopsy yielding Grade Group 2 or higher prostate cancer in 158 patients. One hundred fifty-four or those patients with cancer had a positive result for the biomarker. The sensitivity of the test was 100%, the specificity was 97.56%, positive predictive value was 97.47%, and negative predictive value was 100%.1 These are impressive numbers for a urine biomarker (or any biomarker). This work is certainly promising, BUT, we have seen promising early data on many biomarkers. In this study, the mean PSA in the cancer group was 34.53 ng/mL versus 9.41 in the control (negative) group. Since patients with infection were excluded, the significantly different PSA levels seemed to be selecting the cancers as well. Time and follow up will determine if the "negative biopsy" controls were truly negative. Can the technique and these results be reproduced? The true test will be how this biomarker consistently performs across a broader population of men with a lower, more homogenous PSA elevation. I will eagerly await results of continued study of this promising biomarker for prostate cancer.

Azithromycin can result in severe cholestatic liver disease. We describe two cases of intractable pruritus secondary to drug-induced cholestatic liver injury, unresponsive to symptomatic medical therapy, necessitating and responding well to therapeutic plasma exchange (TPE). The first is a case of a 60-year-old male known to have stable chronic lymphocytic leukemia (CLL) and benign prostatic hyperplasia, and the second is a 46-year-old female known to have primary biliary cirrhosis (PBC) who presented at six weeks and two weeks, respectively, post-mild-COVID-19 pneumonia. Their drug histories were positive for over-the-counter (OCT) azithromycin use during the COVID-19 pneumonia period. They presented with a two-week history of severe itching, associated with sleep deprivation and impaired quality of life. Liver function tests revealed a cholestatic pattern of liver injury. Pruritus remained refractory to multiple lines of treatment including bile acid sequestrants and antihistamines. Rapid and long-lasting relief of the patient's symptoms was observed after three sessions of TPE. Our cases highlight medically recalcitrant cholestatic pruritus as an adverse effect of antibiotic misuse during the recent COVID-19 pandemic. Sustained symptomatic improvements were seen after TPE.

Review
BACKGROUND
Nocardia is an ubiquitous soil organism. As an opportunistic pathogen, inhalation and skin inoculation are the most common routes of infection. Lungs and skin are the most frequent sites of nocardiosis. Testis is a highly unusual location for nocardiosis.
CASE PRESENTATION
We report the case of an immunocompromised 75-year-old-man admitted for fever of unknown origin. He presented with skin lesions after gardening and was first suspected of Mediterranean spotted fever, but he did not respond to doxycycline. Then, physical examination revealed new left scrotal swelling that was compatible with a diagnosis of epididymo-orchitis. The patient's condition did not improve despite empirical antibiotic treatment with the onset of necrotic scrotal abscesses requiring surgery. Nocardia brasiliensis yielded from the removed testis culture. High-dose trimethoprim-sulfamethoxazole and ceftriaxone were started. Multiple micro-abscesses were found in the brain and spinal cord on imaging studies. After 6 weeks of dual antibiotic therapy for disseminated nocardiosis, slight regression of the brain abscesses was observed. The patient was discharged after a 6-month course of antibiotics and remained relapse-free at that time of writing these lines. Trimethoprim-sulfamethoxazole alone is meant to be pursued for 6 months thereafter. We undertook a literature review on previously reported cases of genitourinary and urological nocardiosis; to date, only 36 cases have been published with predominately involvement of kidney, prostate and testis.
CONCLUSIONS
To the best of our knowledge, this is the first case of Nocardia brasiliensis simultaneously infecting skin, testis, brain and spinal cord in an immunocompromised patient. Knowledge on uncommon forms of nocardiosis remains scarce. This case report highlights the difficulty of diagnosing atypical nocardiosis and the importance of prompt bacteriological sampling in case of empirical antibiotics failure.

Gender-affirming surgery includes a range of procedures that help align a transgender or gender diverse person's body with their gender identity. As rates of gender-affirming surgery increase, family physicians will need to have the knowledge and skills to provide lifelong health care to this population. Physicians should conduct an anatomic survey or organ inventory with patients to determine what health screenings are applicable. Health care maintenance should follow accepted guidelines for the body parts that are present. Patients do not require routine breast cancer screening after mastectomy; however, because there is residual breast tissue, symptoms of breast cancer warrant workup. After masculinizing genital surgery, patients should have lifelong follow-up with a urologist familiar with gender-affirming surgery. If a prostate examination is indicated after vaginoplasty, it should be performed vaginally. If a pelvic examination is indicated after vaginoplasty, it should be performed with a Pederson speculum or anoscope. After gonadectomy, patients require hormone therapy to prevent long-term morbidity associated with hypogonadism, including osteoporosis. The risk of sexually transmitted infections may change after genital surgery depending on the tissue used for the procedure. Patients should be offered the same testing and treatment for sexually transmitted infections as cisgender populations, with site-specific testing based on sexual history. If bowel tissue is used in vaginoplasty, vaginal bleeding may be caused by adenocarcinoma or inflammatory bowel disease. (Am Fam Physician. 2024;109(6):560-565.

PURPOSE
To investigate safety and feasibility of performing water vapor thermal therapy (WVTT; Rezum, Boston Scientific, Marlborough, MA, USA) without postoperative catheterization among men with benign prostatic hyperplasia.
METHODS
This is a prospective, single arm, unblinded pilot study of 20 consecutive male patients ages 40-80 who underwent WVTT at a single academic institution. All patients underwent 1 injection per lobe at the point of maximal obstruction based on visualization. Primary outcome was evaluation of voiding parameters, symptom scores, and need for catheterization at 3 day, 1, 3, and 6 month follow up compared to baseline visit 30 days prior to surgery.
RESULTS
Mean age was 65 years (range 55-75). Mean prostate volume and PVR were 43 cc (range 30-68) and 89 cc, with 30% (n = 6) having median lobes. Patients received 2-3 treatments based on presence of bilobar versus trilobar hyperplasia. One patient (55 cc prostate, no median lobe) required catheterization for acute urinary retention on postoperative day 2. No patients required antibiotics for urinary tract infection or inpatient readmission within 30 days. Qmax significantly increased from 6 mL/s to 8, 13, 12, and 14 at 3 days, 1, 3, and 6 months (p < 0.05). IPSS decreased from 17 preoperatively to 10, 6, 7, and 8 (p < 0.05). No significant differences were noted in PVR, IIEF, MSHQ-EjD, or SF-12.
CONCLUSIONS
In well-selected men, catheter-free WVTT is feasible and improved voiding parameters and symptom scores. No changes in sexual function, infectious complications, or readmission were noted. Only 1 patient (5%) required postoperative catheterization within 30 days.

Review
BACKGROUND
Chronic infection and inflammation have been linked to the development of prostate cancer. Dysbiosis of the oral and gut microbiomes and subsequent microbial translocation can lead to pathogenic prostate infections. Microbial-produced metabolites have also been associated with signaling pathways that promote prostate cancer development. A comprehensive discussion on the mechanisms of microbiome infection and the prostate microenvironment is essential to understand prostate carcinogenesis.
METHODS
Published studies were used from the National Center for Biotechnology Information (NCBI) database to conduct a narrative review. No restrictions were applied in the selection of articles.
RESULTS
Microbiome-derived short-chain fatty acids (SCFAs) have been found to upregulate multiple signaling pathways, including MAPK and PI3K, through IGF-1 signaling and M2 macrophage polarization. SCFAs can also upregulate Toll-like receptors, leading to chronic inflammation and the creation of a pro-prostate cancer environment. Dysbiosis of oral microbiota has been correlated with prostate infection and inflammation. Additionally, pathogenic microbiomes associated with urinary tract infections have shown a link to prostate cancer, with vesicoureteral reflux potentially contributing to prostate infection.
CONCLUSIONS
This review offers a comprehensive understanding of the impact of microbial infections linked to intraprostatic inflammation as a causative factor for prostate cancer. Further studies involving the manipulation of the microbiome and its produced metabolites may provide a more complete understanding of the microenvironmental mechanisms that promote prostate carcinogenesis.

PURPOSE OF THE REVIEW
Increasing uptake of gender affirming surgery has allowed for a wider breadth of publication examining complications associated with vaginoplasty. This review aims to provide a comprehensive overview of complications associated with vaginoplasty procedures, focusing on intraoperative, early postoperative, and delayed postoperative complications across different surgical techniques.
RECENT FINDINGS
Intraoperative complications such as bleeding, injury of the rectum, urethra and prostate, and intra-abdominal injury are discussed, with insights into their incidence rates and management strategies. Early postoperative complications, including wound dehiscence, infection, and voiding dysfunction, are highlighted alongside their respective treatment approaches. Moreover, delayed postoperative complications such as neovaginal stenosis, vaginal depth reduction, vaginal prolapse, rectovaginal fistula, and urinary tract fistulas are assessed, with a focus on their etiology, incidence rates, and management options.
SUMMARY
Vaginoplasty complications range from minor wound issues to severe functional problems, necessitating a nuanced understanding of their management. Patient counseling, surgical approach, and postoperative care optimization emerge as crucial strategies in mitigating the impact of complications. Standardizing complication reporting and further research are emphasized to develop evidence-based strategies for complication prevention and management in vaginoplasty procedures.

PURPOSE
To provide more accurate and definitive conclusions regarding the clinical and technical complications associated with the transperineal (TP) and transrectal (TR) approaches, a comprehensive review of observational studies and randomized controlled trials was conducted. This systematic review covered all eligible studies to facilitate a thorough comparison of complications linked to the two fiducial marker insertion methods, TP and TR.
METHODS
A comprehensive search of the literature was conducted, encompassing databases such as PubMed, Embase, and the Cochrane Library, up to July 7, 2023. The relative risk and 95% confidence interval were utilized to evaluate the diagnosis and complication rates.
RESULTS
The final selection for the methodological quality analysis included 13 observational studies that utilized TP and TR gold fiducial insertion approaches. The meta-analysis revealed significantly lower risks of urinary tract infections (UTI) and rectal bleeding with the TP approach.
CONCLUSION
The use of both TP and TR techniques for placing gold seed fiducial markers has proven to be an effective, safe, and well-tolerated method for image-guided radiation therapy in prostate cancer patients. A significant benefit of the TP technique is its ability to avoid rectal puncture, thereby reducing the risk of UTIs. Although the incidence of UTIs and rectal bleeding associated with the TR method is relatively low, these complications can disrupt patient wellbeing and potentially cause delays in treatment.
