Antibiotic Resistance Patterns Among Uropathogens in Female Outpatients Affected by Uncomplicated Cystitis: Focus on Fosfomycin Trometamol.

OBJECTIVES: To report the resistance rate against fosfomycin trometamol among outpatient women with symptoms related to urinary tract infections over a 6-year period in a multicentre, cross-sectional study. METHODS: Urinary samples were collected from three high-volume laboratories from January 2015 to December 2020. The pattern of resistance to fosfomycin was analysed by using the Vitek II automated system. RESULTS: A total of 7289 urinary samples were collected and 8321 strains were analysed during the study period. The most commonly isolated uropathogen was Escherichia coli (n = 6583, 79.1%). The mean resistance rate against fosfomycin was 9.7% (range 7.1-11.3). No statistically significant difference was found between the three laboratories (P = 0.53). There was no significant increase in resistance rate during the study period. The mean resistance rate against fosfomycin was higher among extended-spectrum ß-lactamase (ESBL)-producing bacteria when compared with non-ESBL-producing strains (10.8% vs. 7.9%; P < 0.001). CONCLUSION: Uropathogens isolated from women affected by cystitis remained highly susceptible to fosfomycin. These findings confirm recommendations in international guidelines that advocate fosfomycin trometamol for empirical treatment of uncomplicated cystitis in women.

History of penile implants: from implants made of bone to modern inflatable penile implants.

Penile prostheses are implantable devices used to definitively treat erectile dysfunction when previous forms of treatment have failed. The first example of a penile implant dates to 1935, when a rib was inserted in a neo-phallus reconstructed after a traumatic amputation. Since then, alternative artificial devices were adopted as penile prosthetic implants. The evolution of prosthetic devices had a dramatic thrust in 1973 when the first inflatable penile prosthesis was worldwide presented. Thanks to advances in device materials, design, surgical implant techniques, and perioperative management, nowadays inflatable penile prostheses are one of the most adopted definitive therapy for patients with drug-refractory erectile dysfunction or refusing alternative forms of treatments. Moreover, the clinical indications for inflatable penile prosthesis have also expanded, including female-to-male transmen or men underwent penile reconstruction due to congenital aphallia or traumatic or surgical penile amputation. In order to summarise the process behind the development and evolution of penile prosthesis, we aimed at performing a historical review of the currently available literature to provide an easy and comprehensive overview of the topic. The understanding of the historical process behind the evolution of inflatable penile prostheses will drive further innovation to increase efficiency and the rate of patients satisfaction.

The relationship between the gut microbiota, benign prostatic hyperplasia, and erectile dysfunction.

Microbiota is defined as the group of commensal microorganisms that inhabit a specific human body site. The composition of each individual's gastrointestinal microbiota is influenced by several factors such as age, diet, lifestyle, and drug intake, but an increasing number of studies have shown that the differences between a healthy microbiota and a dysbiotic one can be related to different diseases such as benign prostatic hyperplasia (BPH) and erectile dysfunction (ED). The aim of this review is to give an overview of the role of the gut microbiota on BPH and ED. Gut microbiota modifications can influence prostate health indirectly by the activation of the immune system and the production of proinflammatory cytokines such as IL-17, IL-23, TNF-alpha, and IFN-gamma, which are able to promote an inflammatory state. Gut dysbiosis may lead to the onset of ED by the alteration of hormone levels and metabolic profiles, the modulation of stress/anxiety-mediated sexual dysfunction, the development of altered metabolic conditions such as obesity and diabetes mellitus, and the development of hypertension. In conclusion, much evidence suggests that the intestinal microbiota has an influence on various pathologies including BPH and ED.

Glans penis augmentation: when, how, and why?

The growing demand for glans penis augmentation (GPA) makes it a hot topic in the field of andrological surgery, albeit still widely debated. The lack of high supporting evidence and its technically challenging aspects are the main concerns. The aim of this study was to review the current literature about GPA in order to provide an easy and comprehensive overview of the topic. GPA is suitable for managing both cosmetic and functional issues. Counseling should be the cornerstone of the decision-making process. A thorough understanding of the glans anatomy and treatment strategies remain essential to safely and effectively address the patient's needs. GPA can be performed using injectable fillers or surgical grafting. Glans-shaft penis asymmetries, small glans size, and loss of glans tumescence can be managed by both injectable fillers and surgery. On the other hand, patients with lifelong premature ejaculation can mainly benefit from using injectable fillers. Currently, available studies show promising results but are limited by small sample's size and non-randomized design. Furthermore, treatment-related complications are poorly reported. The long-term efficacy and safety profiles of GPA techniques should be further investigated.
