It is an important task to locate facial feature points due to the widespread application of 3D human face models in medical fields. In this paper, we propose a 3D facial feature point localization method that combines the relative angle histograms with multiscale constraints. Firstly, the relative angle histogram of each vertex in a 3D point distribution model is calculated; then the cluster set of the facial feature points is determined using the cluster algorithm. Finally, the feature points are located precisely according to multiscale integral features. The experimental results show that the feature point localization accuracy of this algorithm is better than that of the localization method using the relative angle histograms.

Background: Traditional in-clinic methods of collecting self-reported information are costly, time-consuming, subjective, and often limited in the quality and quantity of observation. However, smartphone-based ecological momentary assessments (EMAs) provide complementary information to in-clinic visits by collecting real-time, frequent, and longitudinal data that are ecologically valid. While these methods are promising, they are often prone to various technical obstacles.

The forensic examination of AIGC(Artificial Intelligence Generated Content) faces poses a contemporary challenge within the realm of color image forensics. A myriad of artificially generated faces by AIGC encompasses both global and local manipulations. While there has been noteworthy progress in the forensic scrutiny of fake faces, current research primarily focuses on the isolated detection of globally and locally manipulated fake faces, thus lacking a universally effective detection methodology.

Osmotic demyelination syndrome (ODS) is a rare complication associated with rapid sodium changes, typically encountered in patients with severe hyponatremia. ODS in patients with normonatremia (ODSIN) is less recognized. We describe a patient with MRI-detected ODSIN following neurotrauma and reviewed the relevant literature.

Introduction: The prevalence of maxillofacial fractures is rising due to increased road traffic accidents, necessitating prompt and effective management, especially in cases of panfacial fractures. The primary objective in treating such fractures is to restore occlusion and stabilize midface buttresses and pillars.
Case Report: This article presents the case of a 56-year-old male who sustained panfacial fractures following a road accident, exhibiting symptoms including facial pain and nosebleeds.
