Urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL)-producing bacteria have become a growing problem limiting therapeutic options. The aim of this study was to investigate the clinical and microbiological efficacy of amikacin treatment in adult patients with lower UTIs due to ESBL-producing Escherichia coli (Ec) or Klebsiella pneumonia (Kp). We conducted a retrospective study of 36 outpatients aged >18 years with dysuria or problems with frequency or urgency in passing urine; pyuria and a positive urine culture (10(5) cfu/ml) for ESBL producing Ec or Kp which is also resistant to nitrofurantoin, fosfomycin, quinolones and trimethoprim/sulfamethoxazole, between January 2013 and February 2014. Patients received intramuscular amikacin 15 mg/kg/day for 10 days. Clinical success was defined as disappearance of symptoms. Bacteriological success was defined as sterile control urine cultures. 58.3% of patients were female. Age range was 18-89 years. All of the patients had at least one complicating factor. 77.8% of the isolates were E. coli. Clinical success rate was 97.2%. Overall bacteriological success rates were 91.7% on the 3 day of treatment, 97.1% at the end of the treatment and 94.1% on the 7-10 days after treatment. After 28-32 days following the treatment, reinfection was found in 12% whereas relapse was not determined. Nephrotoxicity was developed in one patient. The clinicians should keep in mind that amikacin treatment is an efficient and safe alternative treatment option before the carbapenem treatment especially in patients with lower UTIs caused by ESBL-producing Ec or Kp that are resistant to all oral antibiotics.

Introduction To evaluate the impact of continuous positive airway pressure (CPAP) therapy on overactive bladder (OAB) symptoms in women with obstructive sleep apnea syndrome (OSAS). Material and methods One-hundred and fifty women underwent an overnight polysomnography study between May 2014 and September 2014. Their voiding symptoms were evaluated using the OAB symptom score (OABSS) and International Consultation on Incontinence Questionnaire Short-Form at OSAS diagnosis and approximately 3-months after CPAP therapy. OSAS severity was assessed according to the apnea-hypopnea-index. Results We evaluated 140 women and 111 of them (79.3%) reported symptoms consistent with OAB. There were no statistically significant differences between OSAS severity with a prevalence of OAB (p = 0.92). The prevalence of urinary incontinence (UI) was 35.7% (n = 50) and 39.6% (n = 44) in all patients and patients with OAB, respectively. There were no statistically significant differences between UI with OAB (p = 0.58). Baseline OABSS is comparable between OSAS severity (p = 0.143). After 3-months CPAP therapy, OABSS and ICIQ-SF sum scores were significantly decreased in patients with severe and moderate OSAS (p < 0.01), however, change of OABSS sum score was insignificant in patients with mild OSAS (p = 0.44). Conclusions CPAP therapy improves the OAB, OABSS and ICIQ-SF scores in women with severe and moderate OSAS. OSAS-induced OAB may be alleviated following CPAP therapy.
Diagnosis and treatment in primary bladder small cell carcinoma: Literature review
(2016) Celik, Orcun; Ekin, Gokhan; Ipekci, Tumay; Budak, Salih; Ilbey, Yusuf Ozlem; 27072176
Small cell bladder carcinoma is a rare and frequently fatal disease. It can be distinguished from classical urothelial carcinoma microscopically and immunohistochemically. Small cell bladder carcinoma has histologically similar properties with other small cell carcinomas in other organs. It has a worse prognosis when compared to urothelial bladder cancer. Multimodal treatments are recommended although there is no widely accepted consensus regarding to the treatment algorithm because of its rarity. In this review, clinical properties and diagnosis of small cell bladder carcinoma, its histopathological and immunohistochemical properties and treatment modalities are examined.
