Escherichia coli Nissle 1917 as adjuvant therapy in patients with chronic bacterial prostatitis: a non-blinded, randomized, controlled trial.

PURPOSE: To evaluate the efficacy and safety of Escherichia coli Nissle 1917 (EcN) in association with levofloxacin in patients with chronic bacterial prostatitis (CBP). METHODS: Patients with CBP referred to our clinic from September 2017 to July 2019 were enrolled. At baseline, the symptomatology was assessed with the NIH-Chronic Prostatitis Symptom Index (NIH-CPSI), while the Meares-Stamey test was used to diagnose the infection. Patients were randomized (1:1) in two groups (A and B). All subjects underwent oral administration of Levoxacin® 500 mg once daily for 4 weeks. Only the patients in Group B underwent oral administration of EcN® 320 mg, twice daily for 4 weeks and then once daily for 8 weeks. After 3 months, each patient repeated the NIH-CPSI questionnaire, while the Meares-Stamey test was repeated at 3 and 6 months in patients who reported persistent symptoms. All adverse events (AEs) were recorded. RESULTS: A total of 110 patients were enrolled. After 3 months patients in Group B reported a significantly lower NIH-CPSI score (5.85 ± 3.07 vs. 7.64 ± 3.86; p = 0.009) and biological recurrences rate (9.8 vs. 26.9%; p = 0.043). At 6 months the biological recurrences rate was significantly lower in Group B (8.7 vs. 28.9%; p = 0.038). Only three patients in Group A and six in Group B (p = 0.25) complained mild AEs. CONCLUSIONS: Combination therapy with EcN and levofloxacin allows a better control of symptoms and biological recurrences in patients with CBP, without worsening the safety of the treatment.

Risk Stratification in Hypertrophic Cardiomyopathy. Insights from Genetic Analysis and Cardiopulmonary Exercise Testing.

The role of genetic testing over the clinical and functional variables, including data from the cardiopulmonary exercise test (CPET), in the hypertrophic cardiomyopathy (HCM) risk stratification remains unclear. A retrospective genotype-phenotype correlation was performed to analyze possible differences between patients with and without likely pathogenic/pathogenic (LP/P) variants. A total of 371 HCM patients were screened at least for the main sarcomeric genes MYBPC3 (myosin binding protein C), MYH7 (ß-myosin heavy chain), TNNI3 (cardiac troponin I) and TNNT2 (cardiac troponin T): 203 patients had at least an LP/P variant, 23 patients had a unique variant of uncertain significance (VUS) and 145 did not show any LP/P variant or VUS. During a median 5.4 years follow-up, 51 and 14 patients developed heart failure (HF) and sudden cardiac death (SCD) or SCD-equivalents events, respectively. The LP/P variant was associated with a more aggressive HCM phenotype. However, left atrial diameter (LAd), circulatory power (peak oxygen uptake*peak systolic blood pressure, CP%) and ventilatory efficiency (C-index = 0.839) were the only independent predictors of HF whereas only LAd and CP% were predictors of the SCD end-point (C-index = 0.738). The present study reaffirms the pivotal role of the clinical variables and, particularly of those CPET-derived, in the HCM risk stratification.

Is topical alprostadil an usable and reliable alternative to intracavernous injection for penile dynamic duplex ultrasonography?

No study has yet been done to evaluate topical alprostadil as a less invasive alternative vasoactive agent for Penile Dynamic Duplex Ultrasonography (PDDU) in the diagnosis of erectile dysfunction. The main aim of our study was to evaluate the usability and reliability of topical alprostadil for PDDU compared with standard intracavernous injection. A further objective was to determine the patients' preference between these two different approaches. During session A, patients received injection while during session B, they received topical alprostadil. Each patient underwent both sessions, 1 week apart from the other. A total of 80 patients were enrolled. After 20 min from drug administration, no significant difference was found between the two procedures in terms of peak systolic velocity and end-diastolic velocity, while Erection Hardness Score was significantly higher with injection. Patients reported less pain/discomfort during the procedure in case of topical alprostadil use and an overall preference towards this examination modality. Topical alprostadil could represent a usable and reliable alternative to intracavernous injection for PDDU, with less discomfort and greater preference by patients.

46,XX Testicular Disorder of Sex Development (DSD): A Case Report and Systematic Review.

Background and objectives: XX male syndrome is part of the disorders of sex development (DSD). The patients generally have normal external genitalia and discover their pathology in adulthood because of infertility. There are no guidelines regarding XX male syndrome, so the aim of our study was to evaluate the literature evidence in order to guide the physicians in the management of these type of patients. Materials and Methods: We performed a systematic review of the available literature in September 2018, using MEDLINE, Web of Science, Embase and Google Scholar database to search for all published studies regarding XX male syndrome according to PRISMA guidelines. The following search terms were used: "46 XX male", "DSD", "infertility", "hypogonadism". Results: After appropriate screening we selected 37 papers. Mean (SD) age was 33.14 (11.4) years. Hair distribution was normal in 29/39 patients (74.3%), gynecomastia was absent in 22/39 cases (56.4%), normal testes volume was reported in 0/14, penis size was normal in 26/32 cases (81.2%), pubic hair had a normal development in 6/7 patients (85.7%), normal erectile function was present in 27/30 cases (90%) and libido was preserved in 20/20 patients (100%). The data revealed the common presence of hypergonadotropic hypogonadism. All patients had a 46,XX karyotype. The sex-determining region Y (SRY) gene was detected in 51/57 cases. The position of the SRY was on the Xp in the 97% of the cases. Conclusions: An appropriate physical examination should include the evaluation of genitalia to detect cryptorchidism, hypospadias, penis size, and gynecomastia; it is important to use a validated questionnaire to evaluate erectile dysfunction, such as the International Index of Erectile Function (IIEF). Semen analysis is mandatory and so is the karyotype test. Abdominal ultrasound is useful in order to exclude residual Müllerian structures. Genetic and endocrine consultations are necessary to assess a possible hypergonadotropic hypogonadism. Testicular sperm extraction is not recommended, and adoption or in vitro fertilization with a sperm donor are fertility options.

Cystic nephroma: report of a case and review of the literature.

Cystic nephroma is a rare benign cystic renal tumor, which has been only recently recognized as an exclusively adult histological entity. We present a case of cystic nephroma, together with clinical, radiological, histopathological and immunohistochemical findings. The histopathological differential diagnosis and immunohistochemical features that are potentially useful for refining this tumor are discussed.

Medical expulsive treatment of distal-ureteral stones using tamsulosin: a single-center experience.

PURPOSE: To evaluate the efficacy of the addition of tamsulosin to our standard expulsive pharmacologic therapy for the treatment of distal-ureteral stones. PATIENTS AND METHODS: A series of 96 patients referred to our department for the management of symptomatic distal-ureteral calculi were randomly divided into group 1 (N = 46) who received diclofenac (100 mg/daily) plus aescin (80 mg/daily) and group 2 (N = 50) who received the same therapy plus tamsulosin (0.4 mg/daily) for a maximum of 2 weeks. There were no differences between the groups with respect to age, sex, or stone size. The primary endpoint was the expulsion rate. Expulsion time, need for analgesics, need for hospitalization, and drug side effects were the secondary endpoints. RESULTS: The expulsion rate was significantly higher in group 2 (90%) than in group 1 (58.7%; P = 0.01), and group 2 achieved stone passage in a shorter time (mean 4.4 v 7.5 days, respectively; P = 0.005). Lower analgesic use was found in group 2 (P = 0.003), as well as significantly fewer hospitalizations for recurrent colic (P = 0.01). Both groups experienced few side effects associated with expulsive therapy. CONCLUSIONS: A conservative approach should be considered as an option in the management of uncomplicated distal-ureteral stones. Even if the best pharmacologic expulsive regimen remains to be established, the use of the selective alpha-blocker tamsulosin is recommended in this setting.
