Evaluating Urine Cytology Slide Digitization Efficiency: A Comparative Study Using an Artificial Intelligence-Based Heuristic Scanning Simulation and Multiple Z-Plane Scanning.

Introduction: Digitizing cytology slides presents challenges because of their three-dimensional features and uneven cell distribution. While multi-Z-plane scan is a prevalent solution, its adoption in clinical digital cytopathology is hindered by prolonged scanning times, increased image file sizes, and the requirement for cytopathologists to review multiple Z-plane images.

Methods: This study presents heuristic scan as a novel solution, using an artificial intelligence (AI)-based approach specifically designed for cytology slide scanning as an alternative to the multi-Z-plane scan.

Comparative evaluation of slide scanners, scan settings, and cytopreparations for digital urine cytology.

Background: Acquiring well-focused digital images of cytology slides with scanners can be challenging due to the 3-dimensional nature of the slides. This study evaluates performances of whole-slide images (WSIs) obtained from 2 different cytopreparations by 2 distinct scanners with 3 focus modes.

Methods: Fourteen urine specimens were collected from patients with urothelial carcinoma.

Evaluation of an artificial intelligence algorithm for assisting the Paris System in reporting urinary cytology: A pilot study.

Background: The Paris System for Reporting Urinary Cytology (TPS) has been shown to improve bladder cancer diagnosis. Advances in artificial intelligence (AI) may assist and improve the clinical workflow by applying TPS in routine diagnostic services.

Methods: A deep-learning-based algorithm was developed to identify urothelial cancer candidate cells using whole-slide images (WSIs).

Craniocervical necrotizing fasciitis of odontogenic origin with thoracic extension.

Craniocervical necrotizing fasciitis is an uncommon but aggressive infection with high morbidity and mortality. We present a case of craniocervical necrotizing fasciitis with thoracic extension caused by a dental infection in a 56-year-old man, with a successful outcome involving broad-spectrum intravenous antibiotics and an aggressive surgical debridement.

[Clinical study on delayed flapless implants placement after bone powder grafted immediately in postextraction sockets].

Purpose: To explore and evaluate the clinical outcome of delayed flapless implant placements after bone powder grafted immediately in postextraction sockets.

Methods: 23 patient requiring dental implants after postextractions were selected for this study. The fresh sockets with at least 3 walls (3 or 4 walls) were immediately grafted and filled with artificial bone powders (Bio-oss and demineralized bone powders), covered by ultra-thin titanium membranes.
