Introduction: To identify the predisposing factors, etiological and clinical characteristics as well as the Fournier’s gangrene (FG) severity index (FGSI) in the outcomes of patients with FG. Materials and Methods: The data from 71 patients diagnosed with FG in a period of 17 years were retrospectively reviewed for the age of the patient, their history, predisposing factors, etiology, prodromal symptoms, FGSI, culture results, hospitalization period, surgical interventions, responses to the therapy and complications. Results: All of the patients were Caucasian males, and the mean age was 61.3 (range 36–92) years. The mean duration from the onset of symptoms to surgery was 7.5 days. The mean hospitalization time was 27.4 days and the most common etiological factor for FG was a perineal abscess. The overall mortality rate was 29.6%. The relationship between the number of predisposing factors and mortality rates in patients with FG was the most statistically significant parameter (p = 0.001). Conclusions: Multiple predisposing factors predict a poor prognosis and correlate significantly with mortality. Extension of the disease and the FGSI score were not predictive of outcome. The most essential intervention for stopping the rapidly progressing infectious process of FG consists of early recognition of the disease, proper management of the predisposing factors and aggressive surgical debridement. Such an intervention can improve clinical outcomes.

A majority of patients with bladder cancer present with superficial disease and subsequently, some patients show progression to muscle invasive or metastatic disease. Bladder cancer has a complex genetic process and identification of the genetic alterations which occur during progression may lead to the understanding of the nature of the disease and provide the possibility of early treatment. The aim of the present study was to compare the structural and numerical chromosomal differences and changes in the p16 and p53 genes between low-grade (LG) and high-grade (HG) bladder cancer (BC) using cytogenetic and molecular cytogenetic methods. Between March 2009 and March 2010, cytogenetic analyses were carried out on tumor and blood samples in 34 patients with transitional cell type BC, and on blood samples of 34 healthy patients as a control group. Fluorescence in situ hybridization probes for the p16 and p53 genes were also used to screen the alterations in these genes in 32 patients with BC. The patients were divided into two groups (LG and HG) and the findings were compared. A total of 11 (32.3%) patients exhibited LGBC, 22 (64.7%) exhibited HGBC and one (3%) patient exhibited carcinoma in situ. There were no differences between the LGBC and HGBC groups according to the number of chromosomal aberrations (P=0.714); however, differences between alterations of the p16 and p53 genes were significant (P=0.002 and P=0.039). Almost all structural abnormalities were found to be located to the 1q21, 1q32, 3p21 and 5q31 regions in patients with HG tumors. In conclusion, the p16 and p53 genes were altered more prominently in patients with HG tumors compared with LG tumors. The structural abnormalities in the 1q21, 1q32, 3p21 and 5q31 regions were observed more frequently in patients with HG tumors. These regions may play significant roles in the progression of BC, but further studies are required to find candidate genes for a panel of BC.

Stentless LP is a feasible technique as its stented counterpart. Although it has a relatively high prolonged leakage risk, it could be performed without compromising the success rate by experienced surgeons.

Objective:To compare standard urotherapy with a combination of urotherapy and biofeedback sessions and to determine the changes that these therapies promote in children with dysfunctional voiding.Patients and Methods:The data of 45 patients who participated in the study from January 2010 to March 2013 were evaluated. All patients underwent urinary system ultrasonography to determine post-void residual urine volumes and urinary system anomalies. All patients were diagnosed using uroflowmetry - electromyography (EMG). The flow pattern, maximum flow rate, and urethral sphincter activity were evaluated in all patients using uroflowmetry - EMG. Each patient underwent standard urotherapy, and the results were recorded. Subsequently, biofeedback sessions were added for all patients, and the changes in the results were recorded and statistically compared.Results:A total of forty - five patients were included, of which 34 were female and 11 were male and the average age of the patients was 8.4 ± 2.44 years (range: 5 - 15 years). After the standard urotherapy plus biofeedback sessions, the post-void residual urine volumes, incontinence rates and infection rates of patients were significantly lower than those with the standard urotherapy (p < 0.05). A statistically significant improvement in voiding symptoms was observed after the addition of biofeedback sessions to the standard urotherapy compared with the standard urotherapy alone (p < 0.05).Conclusions:Our study showed that a combination of urotherapy and biofeedback was more effective in decreasing urinary incontinence rates, infection rates and post - void residual urine volumes in children with dysfunctional voiding than standard urotherapy alone, and it also showed that this combination therapy corrected voiding patterns significantly and objectively.
