Purpose: This study's purpose is to classify and analyze caregivers' recognition of the elderly suicidal intents. Methods: This study uses applied Q-methodology to measure human subjectivity in depth. Concretely, 35 statements are composed in depth interviews and literature investigation. Then, Q-cards and distributive chart of Q-sampling were given to 25 caregivers randomly-selected, who were asked to arrange them on a 7-score based. After coding Q-factor analysis is carried out with the PC-QUANL program. Results: Four types of indicators of the elderly suicidal intents were identified by the caregivers. These are Knowledge-based recognition, Behavioral measure based recognition, Negative comprehension and Sympathy. Conclusion: In this study, four types of recognition were yielded among the caregivers and the characteristics of each type were analyzed. These findings may be useful in assessing suicidal potential and nursing interventions.

Purpose: To report clinical appearances and the outcomes of patients treated for wrist laceration with suicidal intent. Materials and Methods: Between March 2005 and February 2008, patients with wrist laceration were treated at our center. Among them, 14 patients with suicidal intent were reviewed retrospectively. They were 8 females and 6 males with a mean age of 33 years at the time of treatment. The side of injured wrist, injured structures, suicidal instrument, the time of injury, a suicidal motive, drug or alcohol abuse or not, indication of combined psychiatric disease, the duration of postoperative treatment, and the results of treatment were analyzed. Results: The injured wrist was the left one in 13 cases (93%), and knife wounds in 11 cases (79%) was the most frequent mechanism of injury. An average of 4.6 structures were injured including 3.5 tendons, 0.57 nerves and 0.5 arteries. The most frequently injured structures were the palmaris longus (71%), FCU (50%), FCR (43%), FDS 3 (36%), FDS 2, median nerve, and ulnar artery (each 29%). Simultaneous injury of both median and ulnar nerves occurred in 3 cases (21%), and simultaneous injury of both radial and ulnar artery occurred in 1 case (7%). The injury time was the night in 12 cases (86%), and the most frequent suicidal motive was human relations such as lover or spouse in 12 cases (86%). In 9 cases (64%), the injured were in a drunken state, 3 cases (21%) had been treated for a psychiatric disease at the time of the injury. The durations of postoperative treatment were an average of 5 days of admission and 1 day follow up. Only 1 case results could be evaluated. Conclusions: Patient's poor compliance in wrist laceration with suicidal intent should be expected and these characteristics may affect the management plan.

Purpose: Non-Suicidal Self-Injury (NSSI), a highly prevalent behavior in adolescents, refers to the direct destruction of one's body tissue without suicidal intent. To date, the prevalence of adolescent self-injury in South Korea and its associated factors remain unknown. This study aims to determine the prevalence of self-injury in Korean adolescents as well as its associated factors. Methods: We assessed 717 middle school students by means of an anonymous self-report survey. Information about demographic characteristics, lifestyle, anxiety and depression, self-esteem, and parenting behavior was obtained. Data were analyzed using $x^2$ test, t-test and multiple logistic regression. Results: NSSI was reported by 8.8% of respondents. Univariate analyses showed associations of exposure to alcohol use, anxiety, depression, self-esteem, and parenting methods with self-injury. In multiple analyses, alcohol use, anxiety, and parental abuse were associated with lifetime self-injury. Conclusion: The rate of NSSI in the South Korea was found to be lower than those of other countries. As our study suggests that alcohol use, anxiety, and parental abuse are associated with lifetime self-injury, health care providers at school should take these factors into account when developing prevention and intervention programs for adolescents.

Objectives : This study aimed to compare the characteristics of suicide attempts among Korean patients with mixed and non-mixed depression. Methods : Patients who visited the emergency room due to a suicide attempt and participated in the Korean Cohort for the Model Predicting a Suicide and Suicide-related Behavior study were included. Using the Montgomery-Asberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS), 111 patients were classified into the mixed depression (n=46) and non-mixed depression groups (n=65). The Koukopoulos Mixed Depression Rating Scale (KMDRS) score was calculated using the MADRS and YMRS scores. Suicide attempt characteristics were evaluated using the Columbia Suicidal Severity Rating Scale (C-SSRS) and Suicide Intent Scale (SIS). Results : In the mixed depression group, the reason item among the ideation intensity score of the C-SSRS was higher, and the deterrent item score was lower. Scores on the timing and suicide note items of the SIS were higher, and scores for overt communication items were lower in the mixed depression group. The KMDRS score was positively correlated with the C-SSRS ideation intensity and total SIS score. After adjusting for additional variables, the KMDRS scores had a significant effect on the C-SSRS ideation intensity and total SIS scores. Conclusions : The mixed depression group showed a difference in the intensity of suicidal ideation and suicidal intention compared to those in the non-mixed depression group. The overall suicidal ideation intensity and suicidal intention increased according to the degree of mixed depression.

The aim of this paper was to review the biomechanics of knife injuries, including those that occur during stabbing rampages. In knife stab attacks, axial force and energy were found to be 1,885 N and 69 J, respectively. The mean velocity of a stabbing motion has been reported to range from 5 to 10 m/sec, with knife motions occurring between 0.62 and 1.07 seconds. This speed appears to surpass the defensive capabilities of unarmed, ordinarily trained law enforcement officers. Therefore, it is advisable to maintain a minimum distance of more than an arm's length from an individual visibly armed with a knife. In training for knife defense, particularly in preparation for close-quarter knife attacks, this timing should be kept in mind. Self-inflicted stab wounds exhibited a higher proportion of wounds to the neck and abdomen than assault wounds. Injuries from assault wounds presented a higher Injury Severity Score, but more procedures were performed on self-inflicted stab wounds. Wound characteristics are not different between nonsuicidal self-injury and suicidal self-wrist cutting injuries. Consequently, trauma surgeons cannot determine a patient's suicidal intent based solely on the characteristics of the wound. In Korea, percent of usage of lethal weapon is increasing. In violence as well as murders, the most frequently used weapon is knife. In the crimes using knife, 4.8% of victims are killed. Therefore, the provision of prehospital care by an emergency medical technician is crucial.

Purpose: This study was conducted to analyze the social factors influencing the 'authenticity of suicidal ideation' based post-suicidal care programs in emergency departments (EDs). Methods: This retrospective study was an analysis using the data of patients who had attempted suicide and visited the ED in tertiary urban hospitals from January 1, 2016, to December 31, 2018. The variables examined included gender, age, history of previous psychiatric disease, suicide method, and the number of previous attempts. Univariate and multivariate logistic regression analyses were conducted to identify factors influencing the registration rate for the community-based post-suicide care program. Results: Overall,1,460 suicides were analyzed, 177 (1.16%) showed a high authenticity of suicide. The social factors influencing the authenticity of suicide intent were the unmarried status of men and women, joblessness, history of mental illnesses, more than two previous suicide attempts, the influence of alcohol, and an attempt to commit suicide after midnight more specifically between 24:00 to 6:00 hours in the morning (p<.05). The factors influencing the severity of the condition of high authenticity suicide patients were low Glasgow coma scores (12 points or less), lactate levels, and oxygen saturation observed in the patients who were admitted to the intensive care unit for treatment and died (p<.05). Conclusion: The need for evidence-based preventive measures and early assessment tools at the emergency medicine level is emphasized to reduce the rate of suicide attempts. If the results of this study are used in the management of suicide prevention, the evaluation of the authenticity of suicide intent will be more likely to be made at the emergency medicine level, allowing the severity to be assessed earlier.

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.

A 47-year-old woman ingested about 12 mg of colchicine with suicidal intent. Colchicine, a highly poisonous alkaloid, is a commonly used treatment for gout, Bechet's disease, and familial Mediterranean fever. Despite the knowledge of its side effects, the risk of a significant overdose is under-appreciated. She suffered from acute multisystem toxicity, including gastrointestinal disorders, bone marrow suppression, alopecia, and probable pancreatitis, but she ultimately recovered with supportive therapy. We report a case of acute colchicine toxicity from a single overdose with a review of the literature.
