"Fine-tuning on AI-driven Video Analysis through Machine Learning; development of an automated evaluation tool of facial palsy.".

Backgrounds: Establishment of quantitative, objective evaluation tool for facial palsy has been a big issue for clinicians and researchers, and in an era of artificial intelligence, AI-driven video analysis can be considered a reasonable solution for this long-discussed issue. We introduced facial keypoint detection, which detects facial landmarks with 68 points, but existing models had been organized almost solely with images of healthy individuals and low accuracy was presumed in the prediction of asymmetric faces of facial palsy patients.The accuracy of existing model was assessed through applying it to the movies of 30 facial palsy patients.

Limb-salvage surgery with vascular reconstruction after lower extremity sarcoma resection: A systematic review and meta-analysis.

Background: Limb-salvage surgery with vascular reconstruction is the current standard treatment when sarcoma involves major vessels of the lower extremity. However, the low incidence of sarcoma and rarity of limb-salvage surgery are limiting factors for the reliable study of limb-salvage surgery. Therefore, a systematic review was conducted to establish better management of lower extremity sarcoma based on currently available evidence.
