        The Effect of Asymptomatic Urethral Caruncle on Micturition in Women with Urinary Incontinence

        Cuneyd Ozkurkcugil,Levend Ozkan,Tufan Tarcan 대한비뇨의학회 2010 Investigative and Clinical Urology Vol.51 No.4

        Purpose: The aim of this study was to evaluate the effect of asymptomatic urethral caruncle (UC) on micturition in women suffering from urinary incontinence. Materials and Methods: A total of 232 patients participated in the study. UC was diagnosed in 50 of 232 patients with urinary incontinence during a physical examination in our clinic. All cases were divided into 2 groups: UC combined with urinary incontinence (group 1) and urinary incontinence only (group 2). Urodynamic evaluations were performed according to the International Continence Society standards. Results: Both groups were similar in terms of voiding diary, pad test and residual urine volume. Urodynamic studies revealed no significant difference between group 1 and 2 (infravesical obstruction: 6% vs. 4.4%; overactive detrusor: 44% vs. 42.9% respectively). The rates of severe IPSS (37.8% vs. 20.9%) and severe cystocele (20.9% vs. 13.8%) were numerically higher in group 1 with no statistically significant difference. Conclusions: Our results suggest that there is no effect of asymptomatic UC on lower urinary tract symptoms in women with urinary incontinence. Therefore, treating asymptomatic UC is unnecessary in these patients. However, during incontinence surgery, it is the surgeon’s decision whether to treat asymptomatic UC.

      • Association Analysis of Single Nucleotide Polymorphisms in miR-146a and miR-196a2 on the Prevalence of Cancer in Elderly Japanese: A Case-Control Study

        Parlayan, Cuneyd,Ikeda, Shinobu,Sato, Noriko,Sawabe, Motoji,Muramatsu, Masaaki,Arai, Tomio Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.5

        Background: Single nucleotide polymorphisms (SNPs) affecting microRNA (miR) sequences may influence carcinogenesis. Our current study primarily aimed to confirm previously conducted association studies between rs2910164 found on miR-146a, and rs11614913 located on miR-196a2 polymorphisms and cancer phenotypes in the Japanese elderly population. rs2910164 (G/C) and rs11614913 (T/C) polymorphisms were determined by genotyping on the samples collected from 1,351 consecutive autopsy cases registered in the Japanese SNPs for geriatric research (JG-SNP) data base. Cancer samples were systematically reviewed, pathologically verified and assessed with respect to miR-146a and miR-196a2 genotypic variation. The current study covered 726 males and 625 females with a mean age of $80.3{\pm}8.9$ years. The study included 524 subjects without cancer and 827 subjects with at least one type of cancer, such as gastric (n=160), lung (n=148), colorectal (n=116) or others. Males with cancers (n=467) were more numerous than females (n=360). Both rs11614913 (CT: TT adjusted odds ratio (OR) 95% confidence interval (95%CI)=0.98 (0.75-1.28), p=0.873, CC: TT adjusted OR (95%CI)=1.06 (0.76-1.47), p=0.737, CT+CC: TT, adjusted OR (95%CI)=0.99 (0.77-1.29), p=0.990), and rs2910164 (CG: CC adjusted OR (95%CI)=1.12 (0.87-1.44), p=0.383, GG: CC adjusted OR (95%CI)=1.03 (0.71-1.48), p=0.887, CG+GG: CC adjusted OR (95%CI)=1.10 (0.87-1.39), p=0.446) polymorphisms did not show significant association with overall cancer in all subjects. However, "CC" genotype in rs11614913 polymorphism was significantly associated with increased gastric cancer (n=160) in all subjects (CC: CT+TT, adjusted OR (95%CI)=1.50 (1.02-2.22), p=0.040). We found that rs11614913 and rs2910164 do not pose general cancer risk, but rs11614913 may influence gastric cancer in Japanese elderly population. Confirmation of our study results requires further investigations with larger subject populations.
