The Japanese Surveillance Committee conducted a second nationwide surveillance of antimicrobial susceptibility patterns of uropathogens responsible for acute uncomplicated cystitis (AUC) in premenopausal patients aged 16-40 years old at 31 hospitals throughout Japan from March 2015 to February 2016. In this study, the susceptibility of causative bacteria (Escherichia coli, Klebsiella pneumoniae, Staphylococcus saprophyticus) for various antimicrobial agents was investigated by isolation and culturing of organisms obtained from urine samples. In total, 324 strains were isolated from 361 patients, including E.

Background: Gonococcal infections are difficult to treat because of their multidrug antimicrobial resistance. The outbreak of antimicrobial-resistant Neisseria gonorrhoeae has begun in Asia and particularly in Japan. Therefore, it is very important that we understand the trend of antimicrobial resistance of N.

Purpose: We investigated the efficacy of 2 α1-blockers with different affinities for the α1-adrenoceptor subtypes silodosin and naftopidil in the treatment of benign prostatic enlargement complicated by overactive bladder.

Materials And Methods: This was a prospective, open label, randomized, multicenter study of 350 outpatients with untreated benign prostatic enlargement associated with urinary urgency at least once per week and an OABSS (Overactive Bladder Symptom Score) of 3 or greater. Patients were randomly assigned to receive silodosin 8 mg per day or naftopidil 75 mg per day.

Article Synopsis
  • * A surveillance study conducted in Japan collected urethral discharge samples from patients in 2009 and 2012 to test for antibiotic resistance in C. trachomatis isolates.
  • * Results showed that no resistant strains were found against common antibiotics like fluoroquinolones, tetracyclines, or macrolides during both years of the study.

Objective: To investigate the etiology of overactive bladder (OAB) symptoms during secondary treatment following initial unsuccessful therapy with α1-blockers in benign prostatic hyperplasia (BPH)/OAB patients.

Methods: BPH/OAB patients were selected if urinary urgency did not improve with initial α1-blocker therapy and if dose escalation was required as secondary treatment for a period of 8 weeks. The overactive bladder symptom score (OABSS), International Prostate Symptom Score (IPSS), and uroflowmetry were evaluated.

Worldwide, the most important concern in the treatment of sexually transmitted infections is the increase in antimicrobial resistant Neisseria gonorrhoeae strains including resistance to cephalosporins, penicillins, fluoroquinolones or macrolides. To investigate the trends of antimicrobial susceptibility among N. gonorrhoeae strains isolated from male patients with urethritis, a Japanese surveillance committee conducted the second nationwide surveillance study.

Neisseria gonorrhoeae is one of the most important pathogens causing sexually transmitted infection, and strains that are resistant to several antimicrobials are increasing. To investigate the trends of antimicrobial susceptibility among N. gonorrhoeae strains isolated from male patients with urethritis, a Japanese surveillance committee conducted the first nationwide surveillance.

Article Synopsis
  • A nationwide surveillance study conducted in Japan from April 2009 to November 2010 examined antimicrobial susceptibility patterns of uropathogens causing acute uncomplicated cystitis in women, involving 43 hospitals.
  • The study identified E. coli as the most common bacteria (77.8%) in urine samples, with significant occurrences of S. saprophyticus in premenopausal women, while also analyzing their resistance to 19 antimicrobial agents.
  • Results indicated high susceptibility of E. coli to fluoroquinolones and cephalosporins, but a rising trend in fluoroquinolone-resistant and ESBL-producing strains highlights the need for careful selection of empirical treatments based on patient characteristics.

Objectives: To estimate correlations among lower urinary tract symptoms (LUTS), bother, and quality of life (QOL) and assess fluctuations in these parameters after α1-blocker administration in patients with benign prostatic hyperplasia (BPH).

Methods: Untreated BPH patients with international prostate symptom scores (IPSS) ≥ 8 and IPSS-QOL scores ≥ 2 were administered tamsulosin at 0.2 mg/day for 4 weeks in a prospective multicenter study.
