Urodynamic Changes Following Fewer Injection Sites of Intravesical Botulinum Toxin in Idiopathic Detrusor Overactivity: A Double-Blinded Prospective Randomized Clinical Trial.

Introduction And Hypothesis: This study was aimed at evaluating the therapeutic effects of a modified intravesical botulinum toxin injection technique (fewer injection sites under local anesthesia), in comparison with the conventional technique for patients with idiopathic detrusor overactivity, considering the urodynamic parameters.

Methods: In this double-blinded randomized clinical trial, 78 adult females with idiopathic detrusor overactivity were divided into two groups: conventional and modified groups. In the conventional method, patients received intradetrusor botulinum toxin injection at 20 sites under general or spinal anesthesia in a trigone-sparing fashion.

The Correlation between EGFR and Androgen Receptor Pathways: A Novel Potential Prognostic Marker in Gastric Cancer.

Background: Despite worthy biologic rationale and numerous studies introducing therapeutic strategies targeting Epidermal Growth Factor Receptor (EGFR), phase III clinical trials have claimed that these current anti-EGFR agents did not significantly improve overall survival of Gastric Cancer (GC) patients. Therefore, to discover flawless candidates of anti-EGFR therapy and ideal prognostic markers, innovative studies are warranted.

Methods: The aim of this study was to assess the expression profile of EGFR in GC, adjacent non-tumor and normal gastric tissues by qRT-PCR, investigating the association of EGFR expression with clinicopathological features, evaluating possible molecular interaction between EGFR and Androgen Receptor (AR), and elucidating novel prognostic marker using Cox regression model.
