TGCTs are classified into two main categories, the adult type and the juvenile type. The adult type is extremely rare, with only 93 known cases reported in the literature. Herein, we present a report of a case of a 30-year-old male patient who presented with a testicular mass and underwent radical inguinal orchiectomy; the pathology examination revealed an adult-type granulosa tumor. Additionally, we review the literature to summarize the scientific knowledge of an entity barely described worldwide.","PeriodicalId":44555,"journal":{"name":"Trudy Instituta Matematiki i Mekhaniki UrO RAN","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88759712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kanda, T. Nishikawa, Momoko Kato, Y. Sugino, Takeshi Sasaki, Manabu Kato, S. Masui, Kouhei Nishikawa, Takahiro Inoue","doi":"10.3390/uro3020018","DOIUrl":"https://doi.org/10.3390/uro3020018","url":null,"abstract":"Fluoroquinolones (FQs) have been traditionally used for prophylaxis against bacterial infection. However, the rapid emergence of FQ-resistant Escherichia coli due to overuse and misuse have resulted in an increase in post-biopsy infections. We requested 723 patients undergoing transrectal or transrectal plus transperineal targeted prostate biopsy to provide preprocedure rectal swabs. The rectal swabs were plated onto deoxycholate hydrogen sulfate lactose agar culture and FQ resistance tests were conducted using the disc diffusion method following the guidelines of the Clinical and Laboratory Standards Institute. All patients undergoing biopsy were given a 1.0 g intravenous injection of cefmetazole (CMZ) 30 min before and 12 h after biopsy. Patients with FQ-resistant organisms received an additional 1.0 g intravenous injection of CMZ every 12 h for an additional 1.5 days, while those without FQ-resistant organisms received levofloxacin 500 mg for 4 days. We evaluated infectious symptoms during the 30 days after the biopsy. We also evaluated the incidence of acute prostatitis within 7 days after the biopsy and isolation rates of FQ-resistant strains. A total of 289 patients (40%) had FQ-resistant isolates on rectal swabs. The overall infectious complication rate was 0.69%. Two patients with FQ-resistant isolates and three patients without them experienced infectious episodes. One patient with FQ-resistant isolates and two patients without them suffered acute prostatitis. The difference in the rates of infectious complication and acute prostatitis rates between FQ-resistant and FQ-susceptible carriers were not significant (p = 1.0 and 1.0, respectively). Post-biopsy sepsis was identified in one patient (0.14%) who had FQ-resistant Escherichia coli. Targeted antimicrobial prophylaxis with cefmetazole based on presence of FQ-resistant isolates on rectal swabs may prevent post-prostate biopsy infectious complications, especially in geographic lesions with a high incidence of FQ-resistant strains in rectal flora.","PeriodicalId":44555,"journal":{"name":"Trudy Instituta Matematiki i Mekhaniki UrO RAN","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88765411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preclinical studies have demonstrated the potential benefits of hyaluronic acid in treating Peyronie’s disease, including antifibrotic, anti-inflammatory, and proangiogenic effects, although more research is needed to fully understand its mechanisms of action. Clinical studies have shown promising results, with hyaluronic acid injections leading to improvements in plaque size, penile curvature, and erectile function, and being well tolerated by patients. The findings suggest that HA injections could be a viable and safe treatment option for Peyronie’s disease, particularly in the early stages of the disease. However, more research is needed to determine the optimal dosage and treatment duration for HA injections, and to confirm its efficacy in the stable phase of Peyronie’s disease. Overall, hyaluronic acid is a potentially effective therapy for Peyronie’s disease, with the ability to inhibit fibrosis and promote angiogenesis, and low risk of adverse effects, making it an attractive option for patients who are unable or unwilling to undergo surgery.","PeriodicalId":44555,"journal":{"name":"Trudy Instituta Matematiki i Mekhaniki UrO RAN","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84683814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
