Our results with enuresis prevalence and associated factors were comparable to other epidemiologic studies from various countries. Furthermore we demonstrated that families in Turkey do not pay sufficient attention to enuresis and most of enuretic children do not receive professional treatment.
Objectives: To evaluate the impact of antibiotic treatment in patients with higher-than-normal prostate-specific antigen (PSA) levels in terms of changes both in total PSA and free/total (f/t) PSA ratios. Materials and Methods: Serum PSA and f/t PSA changes after antibiotic treatment in 85 patients with normal digital rectal examination but elevated age-adjusted serum PSA levels were evaluated with relevance to biopsy results. Results: Serum PSA levels decreased after antibiotic treatment in 47 of 85 patients. The f/t PSA ratio decreased or remained unchanged in 21 and increased in 26 of these 47 cases. Cancer detection rate in the former group was 52.4% (11/21), while it was 7.7% (2/26) in the latter (p = 0.002). There were 38 patients with increased PSA levels after antibiotics. The f/t PSA ratios decreased or remained unchanged in 20 and increased in 18 of these 38 cases. Cancer detection rates were 55% (11/20) in the former and 16.7% (3/18) in the latter group (p = 0.003). Conclusions: The PSA and f/t PSA levels may change with long-term antibiotic treatment in patients with elevated PSA values. The f/t PSA ratio rather than total PSA appears to be more helpful in suggesting prostate cancer in these cases.
This study was aimed to investigate the effects of experimental left varicocele (ELV) repair on hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) expressions and angiogenesis in rat testis. ELVs were surgically created in 26 adult male Sprague-Dawley rats. Thirty days after surgery, ELV repair was performed in 13 of the rats. All rats subsequently underwent orchiectomy 30 days after the last laparotomy. Histology of ELV-repaired testicles was compared to that of the unrepaired (ELV) group. The frequency of positive HIF-1α findings was significantly lower in the ELV-repaired than in the ELV group. The frequency of positive VEGF findings was also lower in the ELV-repaired than in the ELV group, although the difference was not statistically significant (P = 0.238). The mean microvessel density in ELV-repair group was significantly lower than that in the ELV group (P = 0.002). Our study demonstrated that ELV repair may protect tissues from hypoxia and hypoxia-related pathophysiologic events, such as angiogenesis, in rat testis.
Angiogenesis is an important factor in the development and progression of prostate cancer (PCA). We aimed to investigate the values of vascular-endothelial-growth-factor (VEGF) expression level and microvessel density (MVD) in the prediction of PCA diagnosis at repeated prostate biopsy (re-PBx). We retrospectively evaluated 167 patients with re-PBx according to elevated prostate-specific antigen levels, suspicious digital rectal examination, and the presence of premalignant lesions. Patients with PCA on re-PBx were included in the cancer group (n = 17). Patients with benign prostatic hyperplasia or normal tissues on re-PBx were included in the control group (n = 21). The groups were compared according to the expression level of VEGF and MVD in initial prostate biopsy. There was no statistically significant difference between groups according to age and serum prostate-specific-antigen values. The mean VEGF scores of the cancer and control groups were 232.64 ± 11.14 and 183.09 ± 14.56, respectively (p < 0.05). The mean MVD of the biopsy samples in the cancer and control groups were 246.47 ± 17.59 n/mm(2) and 197.33 ± 16.26 n/mm(2), respectively (p < 0.05). The cutoff values of VEGF scores and MVD were set as 200 and 215, respectively, for PCA detection in our study. Our results showed that the expression level of VEGF and MVD significantly increased in the initial prostate-biopsy samples of patients with PCA diagnosed with re-PBx. The evaluation of VEGF expression level and MVD might have an important value in the prediction of PCA at re-PBx. The expression level of VEGF and MVD should be kept in mind as PCA-related histopathological changes that indicate the increased angiogenesis in prostatic tissue.
We could not find any effect of DRE on uroflowmetry parameters. Studies in a larger patient series would be appropriate for recommending DRE before or after uroflowmetry test.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
