Growth differentiation factor 15 (GDF-15), a cytokine within the transforming growth factor-β superfamily, is involved in various malignancies, withimplications in oral squamous cell carcinoma (OSCC). Elevated GDF-15 levels are correlated with unfavorable prognosis, tumor progression, and chemotherapy resistance, and the protein has been identified as a potential diagnostic and prognostic biomarker for OSCC. Personalized treatment strategies based on GDF-15 expression could improve treatment outcomes.

Objectives: This study analyzed the current state of community mental health programs in Korea to develop evidence-based criteria for these programs. Methods: Seventy community mental health facilities nationwide were surveyed about the scope of their operated mental health programs. Details, including program structure, staff expertise, standardization, and quality management, of the 511 programs submitted by the facilities as their representative programs were also analyzed to evaluate their efforts for evidence-based practice. Results: The average number of programs operated by community mental health welfare centers was 15.9. The most common programs were those related to serious mental illness (SMI), followed by child/adolescent mental health programs, early psychosis programs, and non-SMI adult mental health programs. In the case of community addiction management centers, there were 7.2 different addiction-related programs per center. Among the psychiatric rehabilitation facilities for SMI, the average number of programs for SMI was 13.1, with some programs for early psychosis. Of the 511 programs submitted as representative programs in their facilities, only 12.3% were judged to be good evidence-based programs. Conclusion More efforts by mental health professionals and governments are needed to implement evidence-based programs in Korea.

Subcutaneous emphysema is the accumulation of gas or air in loose subcutaneous connective tissue. The use of air-driven handpieces in dental procedures is a common iatrogenic cause of intraoral mucogingival barrier disruption by high-pressure air. This case report describes a 60-year-old woman who underwent prophylactic periodontal treatment with an air-abrasive device and subsequently developed severe bilateral subcutaneous emphysema, extending from the temporal region to the thoracic and mediastinal spaces. Subcutaneous emphysema was suspected based on clinical examination, and paranasal CT was performed for definitive diagnosis. Chest CT was conducted for further evaluation, followed by consultation with the Department of Thoracic Surgery.The patient was admitted for supportive care and prophylactic antibiotics. After 4 days of hospitalization, the symptoms had nearly resolved, and a follow-up paranasal CT showed significant air resorption. The patient was discharged without complications. Although generally benign and self-limiting, subcutaneous emphysema can lead to serious complications such as systemic infection, pneumothorax, and air embolism. This case highlights the importance of prompt diagnosis and appropriate management to prevent further complications.

In recent years, many advances have been made in surgical fields of oral and maxillofacial reconstruction, and the variety and complexity of available surgical approaches consider different functionalities of the jaw and the aesthetics of the face. There is no validated or scientifically proven basis for deciding which flap to use for reconstruction, so decisions are often made based on the direct and indirect experiential knowledge of the reconstructive surgeon. Considering the modified ladder, elevator, and pie reconstructive options, their risk and donor morbidity, and their long-term outcomes, the simplest option that will achieve the best long-term outcome in terms of form and function and with the lowest donor morbidity should be chosen for the patient’s health and social welfare. This manuscript summarizes current options for jaw and facial reconstruction and their limitations by offering updated guidelines for various defect conditions.
