Article Abstract
: In rhegmatogenous retinal detachment (RRD), vitreous cortex remnants (VCRs) may contribute to the development and progression of proliferative vitreoretinopathy (PVR). This study aimed to evaluate potential toxicity and trauma secondary to VCRs visualization and removal during pars plana vitrectomy (PPV) for RRD. : Prospective study on patients with primary RRD who underwent PPV. Imaging assessment included widefield OCT (WF-OCT), ultra-WF retinography and fundus autofluorescence (FAF). During PPV, a filtered and diluted triamcinolone acetonide (TA) solution (20 mg/mL) was used to evaluate the presence and extension of VCRs, removed using an extendible diamond-dusted sweeper (EDDS). After six months, retinal and retinal pigment epithelium toxicity and retinal trauma due to VCRs removal were investigated. : Retinal reattachment was achieved in 21/21 cases included in the study. No signs of retinal or RPE toxicity were detected and WF-OCT performed in the areas of VCRs removal revealed an intact inner retinal architecture in the majority of eyes, with minor and localized inner retinal indentations in 4 cases. : VCRs visualization and removal using TA and EDDS appears to be safe, with no retinal toxicity and very limited and circumscribed mechanical trauma. This approach may contribute to reducing the risk of postoperative PVR.

Background And Objective: Traditional and planimetric plaque indices rely on plaque-disclosing agents and cannot quantify three-dimensional (3D) structures of dental biofilms. We introduce a novel computer-assisted method for evaluating and visualising plaque volume using intraoral scans (IOSs).
Materials And Methods: This was a 4-day, non-brushing, plaque-regrowth study (n = 15).

Background: Breast-conserving surgery (BCS) is the primary surgical approach for patients with breast cancer. The accurate determination of surgical margins during BCS is critical for patient prognosis; however, time constraints and limitations in current pathological techniques often prevent pathologists from performing this assessment intraoperatively. The inability to reliably assess margins during surgery can lead to incomplete tumor removal and the need for additional surgeries.

We present a case of third ventricle colloid cyst surgical resection using a tubular-based endoscopic transcortical approach. Third ventricle colloid are rare benign lesions typically found in the anterolateral part of the third ventricle, close to the foramen of Monro. Several surgical approaches have been employed for their management.

Background: Robotic single-port transvaginal natural orifice transluminal endoscopic surgery (RSP-vNOTES) is an emerging minimally invasive approach that combines the advantages of robotic surgery with scarless transvaginal access. Its application in gynecologic oncology remains limited, particularly for omentectomy during ovarian cancer staging.
Methods: We present the case of a 45-year-old woman with an ovarian granulosa cell tumor (GCT) who underwent supplemental staging surgery following unilateral oophorectomy.
Does Weightbearing Affect Radiographic or Clinical Outcomes in Distal Radius Fractures Treated With Dorsal Bridge Plate Fixation?

Duke University, Durham, NC, USA.
Background: Dorsal wrist spanning plate (DWSP) fixation in distal radius fractures (DRFs) has been proposed to allow earlier mobilization in polytraumatized patients by enabling early weightbearing (WB) through the injured wrist. The purpose of this study is to compare radiographic and clinical outcomes in patients who bore weight through the injured wrist within the early postoperative period with patients who did not bear weight.
Methods: Patients who underwent DWSP fixation at a single institution were retrospectively identified.
