Comparative evaluation of PD-L1 expression and tumor immune microenvironment in molecular subtypes of muscle-invasive bladder cancer and its correlation with survival outcomes.

Objectives: Immune checkpoint inhibitors have revolutionized treatment of platinum-refractory advanced bladder cancer, offering hope where options are limited. Response varies, however, influenced by factors such as the tumor's immune microenvironment and prior therapy. Muscle-invasive bladder cancer (MIBC) is stratified into molecular subtypes, with distinct clinicopathologic features affecting prognosis and treatment.

Immediate second resection versus restage transurethral resection of bladder tumor: A prospective randomized clinical trial (IMMERSE trial).

Background: The role of repeat transurethral resection of bladder tumor (TURBT) for the management of nonmuscle invasive bladder carcinoma is debated, especially when initial resections include detrusor muscle. This study compares immediate second resection (additional deep biopsies in the same session) with standard restage TURBT performed 2-6 weeks post-initial TURBT to determine adequacy in detrusor muscle sampling and compare the disease rate at restage TURBT in both groups.

Material And Methods: A randomized trial was conducted at a tertiary care hospital, including patients aged ≥18 years undergoing TURBT with complete primary tumor resection.

Primary intrarenal hemangioma - A series of 39 cases.

Intrarenal hemangiomas lack concise clinicopathologic information, due to the predominance of single case reports and inclusion of other vascular neoplasms and hemangiomas of perirenal, hilar, and renal vein origin. Herein, in this multi-institutional study we evaluate clinicopathologic features of 39 intrarenal hemangiomas. The median age was 62 years (range = 27-94 years; 2:1 male to female ratio), with left-sided predominance (left = 21, right = 13; one case was bilateral).

Vitamin C-Based Gingival Depigmentation Versus Surgical Depigmentation: A Randomized Clinical Trial.

This study aimed at comparing gingival depigmentation by locally injected vitamin C with surgical depigmentation, in terms of effectiveness and patient acceptability. Forty-two patients presenting with ethnicity-related hyperpigmentation were randomly divided into two groups, Group I ( = 21) was treated with locally injected vitamin C and Group II ( = 21) was treated by surgical depigmentation. The outcome was assessed using Gingival Pigmentation Index (GPI) and Skin Hyperpigmentation Index (SHI).

Reorganization of central auditory pathways in vestibular schwannoma: a diffusion tensor imaging study.

Purpose: Objective information about the central auditory pathways in vestibular schwannoma can guide strategies for hearing rehabilitation and prognostication. This study aims to generate this information using diffusion tensor imaging (DTI).

Methods: This is a prospective observational single center study including 35 patients with vestibular schwannoma and 40 controls.
