A study demonstrates that JAK/STAT hyperactivation-characterized by interferon signature enrichment, STAT1 phosphorylation in keratinocytes/macrophages, and subsequent GBP1/WARS1-mediated cytotoxicity-drives epidermal detachment in TEN. JAK inhibitors (including JAK1-selective agents) suppressed this pathway in murine models and achieved rapid resolution in seven TEN patients.Recent clinical studies have demonstrated the therapeutic efficacy of JAK inhibitors in SJS/TEN management. In this context, we present the case of a 54-year-old woman who presented to the hospital with a 6-day history of rapidly worsening erythema, accompanied by a 4-day history of blistering and erosion. The patient received treatment with methylprednisolone (40 mg/day, weight: 49 kg) and upadacitinib (15 mg/day for 2 weeks).

This article systematically reviews the causes, consequences, and management strategies of facial overfilling, aiming to provide a scientific basis for the prevention and correction of this phenomenon. The causes of overfilling involve technical, patient, and physician-related factors: technical factors include improper injection dosage, depth, and point design; patient factors primarily stem from the excessive pursuit of \"perfect\" facial features and unrealistic expectations; while physician factors are related to insufficient experience, lack of technical proficiency, and misinterpretation of aesthetic standards. The consequences of overfilling include aesthetic imbalance, health risks, and psychological issues. To effectively prevent and manage overfilling, this article proposes detailed preventive strategies, including preoperative assessment and design, patient education, intraoperative layered injection techniques, and regular postoperative follow-ups. For cases where overfilling has already occurred, non-surgical correction and surgical correction are the primary treatment methods. Additionally, psychological support and the application of portable ultrasound technology play important roles in the correction process. Future research directions include the development of quantitative assessment tools, optimization of prevention and management strategies, and the development of new filler materials and technologies.
