Article Synopsis
  • New image enhancement techniques and improved endoscopic quality haven't increased the routine use of the resect-and-discard approach for small polyps, even though endoscopists can achieve the necessary quality to perform optical diagnoses.
  • Recent advancements in Artificial Intelligence, specifically Computer Assisted Characterisation (CADx), show promise for better diagnosing diminutive polyps and potentially enhancing the adoption of resect-and-discard strategies.
  • While pathology diagnosis faces challenges like errors and variability, new AI-driven paradigms are emerging, but further research and real-world implementation studies are needed to boost acceptance and address liability concerns among endoscopists.

Background: The mechanisms underlying the initiation and progression of bifurcation versus lateral wall aneurysms are not well understood. Computational fluid dynamics (CFD) can improve the understanding of these mechanisms and can consequently help identify patients at higher risk for developing aneurysms and monitor them more closely.

Observations: A 36-year-old man presented with a ruptured anterior communicating artery aneurysm, which was successfully treated with microsurgical clipping.

Article Synopsis
  • Patients undergoing open radical cystectomy have a high risk of needing blood transfusions, and the study investigates the use of tranexamic acid (TXA) to potentially reduce this risk.
  • The TACT trial was a randomized, double-blind study conducted in 10 academic centers from 2013 to 2021, involving patients scheduled for this type of surgery due to bladder cancer.
  • Results showed no significant difference in RBC transfusion rates between the TXA group and the placebo group, with both groups needing transfusions at similar rates up to 30 days post-surgery.

Background And Objectives: Complete resection of epileptogenic zone is the single most important determinant of favorable seizure outcomes in resective surgery. However, identifying and resecting this zone is challenging in patients harboring diffuse; MRI-occult malformations of cortical development, such as focal cortical dysplasia; or acquired pathology, such as Rasmussen encephalitis. Intraoperative adjuncts that can aid in identifying the lesion and/or epileptogenic zone can optimize the extent of resection and seizure outcome.

Functional coactivation between human brain regions is partly explained by white matter connections; however, how the structure-function relationship varies by function remains unclear. Here, we reference large data repositories to compute maps of structure-function correspondence across hundreds of specific functions and brain regions. We use natural language processing to accurately predict structure-function correspondence for specific functions and to identify macroscale gradients across the brain that correlate with structure-function correspondence as well as cortical thickness.

Introduction: Operculo-insular epilepsy (OIE) is a rare condition amenable to surgery in well-selected cases. Despite the high rate of neurological complications associated with OIE surgery, most postoperative deficits recover fully and rapidly. We provide insights into this peculiar pattern of functional recovery by investigating the longitudinal reorganization of structural networks after surgery for OIE in 10 patients.

Surgical management of drug-resistant epilepsy (DRE) in patients with multiple periventricular nodular heterotopias (PVNHs) is challenging. Identifying the location of seizure onset within these complex epileptic networks is difficult, and open resection carries risks of injury to surrounding functional white matter tracts such as optic radiations (ORs). The authors demonstrate tractography-assisted laser ablation of a single nodule in a patient with DRE and multiple PVNHs.
