We aimed to perform functional analysis of miR-145-5p in prostate cancer (PCa) cells and to identify targets of miR-145-5p for understanding its role in PCa pathogenesis. PC3, DU145, LNCaP PCa, and PNT1a nontumorigenic prostate cell lines were utilized for functional analysis of miR-145-5p. Its overexpression caused inhibition of proliferation through apoptosis and reduced migration in PCa cells. SOX2 expression was significantly decreased in both mRNA and protein level in miR-145-5p-overexpressed PCa cells. We proposed that miR-145-5p, being an important regulator of SOX2, carries a crucial role in PCa tumorigenesis.
The aim of the study is to evaluate the efficacy and safety of retrograde intrarenal surgery (RIRS) to treat renal stones in preschool age (<7 years) children. From September 2005 to May 2013, a total of 65 children (31 boys and 34 girls) with 72 renal stones were treated using RIRS. Patients were considered stone-free when the absence of residual fragments was observed on imaging studies. In the presence of residual calculi >4 mm, a second-stage RIRS was performed. The pre-operative, operative and post-operative data of the patients were retrospectively analyzed. A total of 65 patients with a mean age of 4.31 ± 1.99 years (6 months-7 years) were included in the present study. The mean stone size was 14.66 ± 6.12 mm (7-30 mm). The mean operative time was 46.47 ± 18.27 min. In 5 (7.69%) patients, the initial procedure failed to reach the renal collecting system and ended with the insertion of a pigtail stent. The stone-free rates were 83.07 and 92.3% after the first and second procedures, respectively. Complications were observed in 18 (27.7%) patients and classified according to the Clavien system. Post-operative hematuria (Clavien I) occurred in 6 (9.2%) patients, post-operative urinary tract infection with fever (Clavien II) was observed in 10 (15.4%) patients, and ureteral wall injury (Clavien III) was noted in 2 (3%) patients. RIRS is an effective and safe procedure that can be used to manage renal stones in preschool age children.
Introduction: Recent experiments have demonstrated that polycomb group gene enhancer zeste homolog 2 (EZH2) is highly expressed in many cancer types. Therefore, we aim to demonstrate EZH2 gene expression in transitional cell bladder cancer. Patients and Methods: The reverse transcriptase-polymerase chain reaction (RT-PCR) was used for detection of EZH2 mRNA levels in healthy and cancerous human bladder specimens. Also, expression of the particular protein was determined by Western blotting and immunohistochemistry to confirm RT-PCR results. Results: Gradually increased expression of EZH2 was detected by mRNA and protein levels in highly advanced bladder cancer specimens. In contrast, 100% of control subjects were negative for EZH2 expression. The expression of EZH2 was more frequent in G3 (92%) than G1-G2 (62–63%) and more frequent in T1-2 (72–85%) than Ta (56%). Western blot analysis results confirm the RT-PCR results. Conclusions: EZH2 overexpression precedes high frequencies of proliferation and the gradual advance of bladder cancer. These observations suggest that deregulated expression of EZH2 is associated with bladder carcinoma.
Introduction
Hypothyroidism is a common hormonal disorder in women that may affect the phases of female sexual function.
Aim
To investigate female sexual function in patients with clinic hypothyroidism and subclinic hypothyroidism.
Methods
A total of 25 women with clinic hypothyroidism (group 4), 25 women with subclinic hypothyroidism [thyroid stimulating hormone (TSH) value ≤10 mU/L (group 2), TSH value >10 mU/L (group 3)], and 20 age matched voluntary healthy women controls (group 1) were included in the study. All the subjects were evaluated with a detailed medical and sexual history, including a female sexual function index (FSFI) questionnaire for sexual status and the Beck Depression Inventory for psychiatric assessment.
Main Outcome Measures
The levels of serum TSH, thyroid hormones, prolactin (PRL), free testosterone, estradiol, follicle-stimulating hormone, luteinizing hormone, lipid profile, and blood glucose were measured.
Results
Female sexual dysfunction (FSD) was diagnosed in 14 of 25 patients (56%) in group 4, in 6 of 11 patients (54.6%) in group 3, in 2 of 14 patients (14.6%) in group 2, and while only 3 of 20 the control group of women (15%) had FSD (P = 0.006). The mean total FSFI scores were 23.9 in the group 4, 26.03 in the group 3, 29.2 in the group 2, and 32.30 in the control group (P <0.0001). The mean BDI score for clinic hypothyroidic patients was significantly greater than the scores for the control group and for the group 2 (P = 0.017 and P = 0.043, respectively). The mean PRL levels for patients in group 4 and group 3 were found to be significantly higher than the level for controls (P <0.0001), whereas other serum hormone levels were not different among groups.
Conclusions
A significant percent of women with clinic hypothyroidism and subclinic hypothyroidism with TSH values >10 mU/L had sexual dysfunction. Hyperprolactinemia, hyperlipidemia, and depression were associated with FSD in clinic hypothyroidism. Different than clinic hypothyroidism depression was not associated with FSD in subclinic hypothyroidism with TSH values >10 mU/L.
The aim of this study was to investigate the effectiveness and reliability of the micro-percutaneous nephrolithotomy (PNL) method for the management of kidney stones. We performed a retrospective analysis of 136 patients (140 renal units) who underwent micro-PNL for renal stones between September 2011 and February 2013 in four referral hospitals in Turkey. The selection of treatment modality was primarily based on factors such as stone size and location. In this study, we analyzed patient- and procedure-related factors. The mean age of patients in this study was 28.7 ± 20.6 (1-69) years, and the mean stone size was 15.1 ± 5.15 (6-32) mm. Conversion to mini-PNL was required in 12 patients. All interventions were performed with the patient in the prone position, except for the 3-year-old patient with the pelvic kidney who was placed in the supine position. The mean hospital stay was 1.76 ± 0.65 (1-4) days, and the mean drop in the hemoglobin level was 0.87 ± 0.84 (0-4.1) mg/dL. One of our patients required transfusion. Ureteral J stent was implanted in nine (6.43 %) patients because of residual stones. Seven (6.43 %) patients complained of postoperative renal colic which was managed conservatively. Abdominal distension related to extravasation of the irrigation fluid was observed in three patients (2.19 %). There were no other postoperative complications. An overall success rate of 82.14 % was achieved. Micro-PNL can be effectively and safely used for small and moderate kidney stones resistant to shock wave lithotripsy or as an alternative to other minimally invasive treatment methods.
