Deliberate self-harm (DSH) is the act of deliberately harming your own body, such as cutting or burning yourself, without suicidal intent. It has especially become a problem among adolescents and college-age students in institutional settings such as boarding schools, Greek houses, detention centers and hospitals. We focus on contagion of DSH among adolescents and young adults by creating a deterministic epidemiological model. We study the impact of actual peer pressure, virtual peer pressure (the Internet) and treatment analytically in terms of a basic reproduction number through stability analysis of a system of ordinary differential equations. All parameters are approximated and results are also explored by simulations. The model shows that DSH is present in an endemic state in the population considered, and the control strategies are discussed.

Purpose: This study was conducted to evaluate the effect of Mindfulness-based Emotion Management Training for adolescents immersed in self-harm behaviors. Methods: The participants were 61 middle school students located in Seoul. Thirty students were assigned to the Mindfulness-based Emotion Management Training (M-EMT) group and the other 31 students were assigned to the waitlist group. The students in the M-EMT group participated in a total of 12 sessions, twice a week, for 6 weeks. The modules of the program comprised of mindfulness for emotion, mindfulness for behavior/impulse, mindfulness for thought, and coping with self-harming behavior. The Distress Tolerance Scale, Deliberate Self-Harm Inventory, Cognitive Emotion Regulation Questionnaire, and Scale Suicidal Ideation were assessed at baseline and post-intervention. Results: Compared to the waitlist group, the intervention group exhibited a statistically significant improvement in distress tolerance and cognitive emotion regulation and a statistically significant reduction in self-harming behaviors and suicidal ideation. Conclusion: These results support the hypothesis that mindfulness-based emotional management training has a positive effect on reducing self-harming behaviors and enhancing distress tolerance and cognitive emotional regulation.

1. 하순에 심한 self-mutilation wound를 야기한 Lesch-Nyhan syndrome 환아에서 상하악 유전치에 치관부 절단 및 치수 절제술을 시행하여 치아에 의한 자해를 방지하였다. 2. 장치를 이용한 치료가 어려운 경우 발치가 고려되기도 하나 본 증례에서는 발치보다 보존적인 술식으로 만족할 만한 결과를 얻었다.

Objectives: This study examined the associations between Internet addiction and suicide and non-suicidal self-injury (NSSI) among South Korean adolescents. Methods: We conducted a cross-sectional study of 1694 Korean adolescents. The suicidal Ideation Questionnaire and Deliberate Self-Harm Inventories were used to identify high-risk suicide and NSSI groups, respectively. Internet addiction was assessed using the Internet Addiction Scale. Other questionnaires included sociodemographic data, perceived academic stress, and daily life-related factors. We also performed a logistic regression analysis using the high suicide risk and NSSI groups as dependent variables. Results: The high suicide risk and NSSI prevalence rates among participants were 11.8% and 28.3%, respectively. A multivariable logistic regression analysis revealed that Internet addiction is associated with higher suicide risk and NSSI. Additionally, being female and academic stress were significant suicide risk factors, while male participants had a higher NSSI prevalence. Conclusion: Our results suggest that monitoring adolescents' Internet use and providing education to prevent Internet addiction would lower high suicide and NSSI risk. Moreover, suicide and NSSI risk screening in adolescents with Internet addiction and providing suitable interventions will be essential for the preventing suicide and NSSI.

뇌성마비(cerebral palsy)는 비진행성의 정신, 운동 장애를 총칭하는 용어로, 소아 장애의 흔한 원인이 된다. 자해 행위란(self-injurious behavior) 자살 의도없이 자신의 신체 일부를 고의적으로 손상시키는 것으로, 종종 반복적인 행동으로 나타난다. 소아에서의 이러한 자해 습관은 정상적인 어린이에서는 드물며, 증후군, 유전질환, 정신지체 어린이 등에서 그 발생률이 높게 보고된다. 구강 내 자해 행위의 가장 흔한 유형은 혀나 입술 혹은 구강 점막을 물어뜯는 것이다. 이러한 자해 행위를 조절하기 위하여 행동 수정법, 약물 치료, 신체 속박술, 치과적 장치의 적용, 외과적 수술 또는 치아 발치술 등의 다양한 방법들이 제시되었다. 이 중 마우스가드 등의 치과적 장치를 이용한 방법은 구강 내 자해 행위의 감소와 조직의 보호를 위해 가장 보존적이며 적합한 방법이라고 사료된다. 본 증례에서는 자해 습관에 의해 하순과 협점막에 궤양성 병소를 가진 뇌성마비 환아에 있어서, 변형된 마우스가드를 이용하여 자해에 의한 손상을 방지하고 만족할 만한 치유 양상을 보였기에 이를 보고하는 바이다.
