Article Synopsis
- - The study aimed to develop a deep learning segmentation model to locate basal cell carcinoma (BCC) on Mohs surgery (MMS) frozen section slides, which is crucial for precise tumor removal.
- - Researchers utilized a dataset of 348 tissue slides and trained the model using the Ultralytics YOLOv8 framework, achieving varying sensitivity and specificity rates by BCC subtype.
- - Results indicated good overall performance with a sensitivity of 71% and specificity of 75%, but highlighted the need for improved performance metrics for clinical application in segmentation studies.
Background: Solid organ transplant recipients with cutaneous squamous cell carcinoma (CSCC) have an increased risk of poor outcomes. However, a recent study demonstrated that immunosuppression is not an independent risk factor for these poor outcomes after controlling for primary tumor stage.
Objective: To evaluate whether transplant status is an independent risk factor for poor outcomes in CSCC.
Background: Current understanding of the etiology, natural history, and outcomes of acute generalized exanthematous pustulosis (AGEP) has been limited, with most available studies consisting of small or heterogenous cohorts.
Objectives: The aim of this study was to further characterize associated factors and disease outcomes of AGEP.
Methods: A cross-sectional study design was employed with formal inclusion and causality criteria.
Nonpurulent cellulitis lacks a gold standard to distinguish noninfectious sources of inflammation. Two models have been created that evaluate cellulitis. The ALT-70 model was created to reduce the overdiagnosis of cellulitis and provide clinical direction.

- - Factitial Dermatitis (FD) is challenging to diagnose since patients create their own skin lesions and often give misleading medical histories.
- - A study at Ohio State University examined records from 2012 to 2017 and identified 32 patients with FD out of 189 candidates, finding a higher prevalence among females and lesions often on upper extremities.
- - Understanding the distinct patterns of FD presentation can lead to faster diagnoses and better resource management in hospitals, ultimately enhancing patient care.
In 2019, the World Health Organization (WHO) listed vaccine hesitancy in its top ten threats to global health. Vaccine hesitancy is a "delay in acceptance or refusal to vaccinate despite availability of vaccination services". Urban areas with large amounts of vaccine hesitancy are at risk for the resurgence of vaccine-preventable diseases (VPDs).
