Colonisation and infection with extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) is an emerging problem. The aim of this study was to investigate whether colistin, which is reported to be effective against multiresistant enterobacteria, prevents ESBL-E colonisation in neonates. For prophylaxis of necrotising enterocolitis, oral gentamicin (15 mg/kg/day) is routinely used in all neonates hospitalised at the Neonatal Intensive Care Unit of University Hospital Graz (Austria). During the study period from May 2005 to September 2007, three ESBL-E outbreaks (total duration 18 months) occurred. During these outbreaks, gentamicin was immediately replaced by oral colistin (8 mg/kg/day) in all hospitalised neonates. All neonates colonised with ESBL-E during the study period were retrospectively analysed with regard to the influence of colistin on ESBL-E colonisation. Genetic relatedness of isolates was assessed by repetitive sequence-based polymerase chain reaction (rep-PCR). During the study period, 30 (4.5%) of 667 neonates were colonised with ESBL-E. Twelve of twenty-one patients colonised with Klebsiella pneumoniae (ESBL-Kp) and one of nine patients colonised with Klebsiella oxytoca (ESBL-Ko) had received oral colistin at time of colonisation with ESBL-E. Amongst ESBL-Kp, the rate of colistin resistance was significantly higher in the colistin group (P=0.0075). Four different clones of ESBL-Kp and three different clones of ESBL-Ko were isolated, indicating the occurrence of patient-to-patient transmission. Colistin-resistant as well as colistin-susceptible isolates were detected within the same clones, indicating induction of resistance. At the dosage used, oral colistin did not prevent colonisation with ESBL-E and appeared to select colistin-resistant strains or to induce colistin resistance.
KeywordsTURP · Geriatric · Outcome · Geriatric assessment · Benign prostatic hyperplasia · Lower urinary tract symptoms Abstract Purpose: To determine the impact of a simple preoperative geriatric assessment on the outcome in older patients with recurrent urinary retention who underwent desobstructive surgery. Patients and Methods: Patients aged 75 years or older with recurrent urinary retention referred for TURP entered this prospective, multicentre study. Several demographic, intra-and postoperative parameters were assessed. Preoperative geriatric assessment was performed by the 7-item Canadian Study of Health and Ageing (CSHA) frailty scale (1: very fit, 7: severely frail; completion takes less than a minute). The main outcome parameters were successful voiding rates at discharge and 3 months postoperatively. Results: A total of 54 patients were recruited; 42 (77.8%) patients had a CSHA index of 1-3 and were considered as "fit", the remaining 12 (22.2%) formed the "frail" group (CSHA index 4-7). Age was identical in both cohorts (79.5 ± 3.7 vs. 79.7 ± 3.3 years); differences were demonstrable for the American Society of Anesthesiologists (ASA) score (p = 0.001), the number of daily medications (> 4: 32 vs. 75%, p = 0.02), falls within the past 6 months (12 vs. 33%), and the necessity of home/nursing care (5 vs. 42%, p = 0.004). Intra-and perioperative complications, duration of postoperative catheterization, and length of hospitalization were identical in both cohorts. The success rate at discharge was 80.6% in fit and 75.0% in frail patients; the respective values at 3 months were 95.2 and 83.3%. Conclusions: A simple 1-min geriatric assessment tool can predict -to a certain extentthe outcome of desobstructive surgery in older patients with recurrent urinary retention. Fit patients achieve an excellent outcome while frail patients might benefit from a more indepth urodynamic/geriatric evaluation.
Introduction and Objectives: Bladder cancer is characterized by gender-dependent disparities. To further address this issue, we analysed a prospective, multicentre cystectomy registry. Methods: An online database was developed that included patient demographics, intra/perioperative data, surgical data and in-house complications. Results: Four hundred fifty-eight patients (112 [24.5%] women and 346 [75.5%] men) were analysed. Men and women were comparable regarding age (mean 68 years), body mass index (mean 26.5) and the mean Charlson score (4.8). Women had more advanced tumour-stages (pT3/pT4; women: 57.1%; men: 48.1%). The rate of incontinent urinary diversion was higher in women (83.1%) than in men (60.2%) and in a multivariate analysis, the strongest predictors were M+ status (OR 11.2), female gender (OR 6.9) and age (OR 6.5). Women had a higher intraoperative blood transfusion rate. The overall rate of in-house complications was similar in both genders (men: 32.0%, women: 32.6%). Severe (Clavien-Dindo grade >2) medical (women: 6.3%; men: 5.2%) and surgical (women: 21.5%; men: 14.4%) in-house complications, however, were more frequent in women. Conclusions: This multicentre registry demonstrates several gender-related differences in patients undergoing radical cystectomy. The higher transfusion rate, the rare use of orthotopic bladder substitutes and the higher in-house complication rate underline the higher complexity of this procedure in women.
Introduction: Clinical stage 1 (CS1) nonseminomatous (NS) germ cell tumors involve a 30% probability of relapse upon surveillance. Adjuvant chemotherapy with one course of bleomycin, etoposide, and cisplatin (1xBEP) can reduce this risk to <5%. However, 1xBEP results are based solely on five controlled trials from high-volume centers. We analyzed the outcome in a real-life population. Patients and Methods: In a multicentric international study, 423 NS CS1 patients receiving 1xBEP were retrospectively evaluated. Median follow-up was 37 (range, 6–89) months. Primary end points were relapse-free and overall survival evaluated after 5 years. We also looked at associations of relapse with clinico-pathological factors using stratified Kaplan–Meier methods and Cox regression models. Treatment modality and outcome of recurrences were analyzed descriptively. Results: The 5-year relapse-free survival rate was 96.2%. Thirteen patients (3.1%; 95% confidence interval, 1.65–5.04%) relapsed after a median time of 13 months, of which 10 were salvaged (77%). Relapses were mostly confined to retroperitoneal nodes. Three patients succumbed, two to disease progression and one to toxicity of chemotherapy. Pathological stage >pT2 was significantly associated with relapse rate. Conclusion: The relapse rate of 3.1% found in this population of NS CS1 patients treated with 1xBEP at the routine care level was not inferior to the median rate of 2.3% reported from a meta-analysis of controlled trials. Also, the cure rate of relapses of 77% is consistent with the previously reported rate of 80%. This study clearly shows that the 1xBEP regimen represents a safe treatment for NS CS1 patients.
In nonagenarians with bladder tumours, pTa/pT1/≥pT2 stages are almost evenly distributed and two-thirds of patients had no recurrence after transurethral resection of the bladder. The mean OS was 1.3 years, and 6 months for ≥pT2 tumours. Further case-series of patients in this specific age-group are required to identify the best management of this increasing proportion of patients with bladder tumours.
