Vasodilatory effects of tadalafil in an animal model of cerebral vasospasm: Comparative analysis with oral nimodipine.

Objectives: Cerebral vasospasm is one of the most fatal complications after spontaneous aneurysmal subarachnoid hemorrhage. Although various treatments have been tried for the treatment of cerebral vasospasm so far, the effect is insignificant or temporary except for oral nimodipine. Phosphodiesterase isozyme type 5 inhibitor, which is used to treat erection dysfunction, recently has been known to have a cerebrovascular vasodilation.

Albumin-to-Alkaline Phosphatase Ratio as a Novel Prognostic Factor in Patients Undergoing Nephrectomy for Non-Metastatic Renal Cell Carcinoma: Propensity Score Matching Analysis.

Introduction: To evaluate the prognostic value of albumin-to-alkaline phosphatase ratio (AAPR) on recurrence and survival in patients with non-metastatic renal cell carcinoma (RCC) treated with radical or partial nephrectomy.

Patients And Methods: Between June 1994 and December 2018, 491 patients with RCC who underwent radical or partial nephrectomy at 2 institutions were enrolled in this study. Recurrence-free survival (RFS) and cancer-specific survival (CSS) analyses were performed to distinguish the differences in postoperative recurrence and survival between patients stratified by an optimal cut-off value of AAPR.

RESIDUAL VITREOUS CORTEX AT THE FOVEA DURING VITRECTOMY FOR PRIMARY RHEGMATOGENOUS RETINAL DETACHMENT REPAIR.

Purpose: To investigate the frequency of residual cortex and the effectiveness of removal of residual cortex in the fovea during vitrectomy for primary rhegmatogenous retinal detachment repair.

Methods: We retrospectively reviewed the charts and the operative videos of the 80 patients (80 eyes) who underwent vitrectomy for repair and who were observed for more than 6 months. After triamcinolone acetonide injection, we observed residual cortex on the surface of the retina.
