Introduction: We assessed the pathological characteristics of the radical prostatectomy specimen, the rate of biochemical failure and the functional outcome after surgery, in terms of incontinence and erectile dysfunction rate, in patients on statin medication. Materials and Methods: A total of 588 patients with a mean age 65.2 years (SD = 5.7 years) participated in the study. All patients were contacted and interviewed. Results: Users who had been on statin medication for more than 2 years had lower levels of preoperative serum PSA (p = 0.034), a 2.76 times greater likelihood of being staged as pT3a to pT3b rather than pT2a to pT2c, and a 5.39 times greater likelihood of having a postoperative Gleason score equal to seven or more. Positive surgical margins and urinary incontinence were not significantly associated with statin use. The probability of erectile dysfunction was significantly greater for statin users. Conclusion: Statin medication was associated with a statistically significantly lower PSA value and an increased rate of high Gleason score and pathologic stage in patients receiving medication for more than 2 years. Statins were found to be an independent predictor of recurrence. Lastly, statin users were more likely to present with preoperative and postoperative erectile dysfunction. Copyright © 2013 S.

PURPOSE. To investigate the anatomic and electrophysiologic changes of the macula and the optic nerve in patients with Parkinson disease (PD) without visual impairment. METHODS. Thirty-two eyes of 16 patients with PD (group A) without visual impairment were tested. Visual acuity was 20/20 or better and visual fields as well as color vision testing results were normal. Also, no retinal lesions were assessed. Patients in group B (40 eyes of 20 patients) were age- and sex-matched control subjects. All study participants underwent a comprehensive ophthalmic examination, multifocal electroretinogram (mfERG) recording, and optical coherence tomography (OCT) scan. Thickness of retinal nerve fiber layer (RNFL) along a 3.4-mm-diameter circle centered on the optic nerve head was evaluated using third-generation OCT. RESULTS. The mean P1-response density amplitude of ring 1 of mfERG was 136.69 nV/deg2 in patients with PD and 294 nV/deg2 in control subjects and the difference was highly significant. On the contrary, these values in ring 2 and 3 did not differ statistically between controls and patients with PD. The mean inferior and temporal RNFL thickness was significantly lower in patients with PD than in control subjects (p<0.0001 and p=0.0045, respectively). CONCLUSIONS. In patients with PD with normal vision, we found a decrease in the electrical activity of the fovea as well as in the thickness of the RNFL. Multifocal electroretinogram and OCT scan objectively detect early subclinical PD-associated visual functional impairment. © 2010 Wichtig Editore.
