Suicide is a major public health concern worldwide, and various mental and physical illnesses are known to be associated with suicidal behavior. This study aimed to review the literature on the association between dermatological conditions and suicidal behavior—including suicidal ideation, suicide attempts, and suicidedeath—and to explore the potential mechanisms by which dermatologic disorders may influence suicidal behav-ior. Numerous studies suggest that major dermatologic disorders such as acne, psoriasis, atopic dermatitis, and hidradenitis suppurativa may increase the risk of suicidal behavior. However, most of these studies are crosssectional or case-control in design, limiting the ability to draw causal inferences. Moreover, inconsistencies in measurements of suicidal behavior across studies hinder the interpretation of results. Dermatological conditions are hypothesized to affect suicidal behavior through comorbid psychiatric disorders (such as depression and anxiety), sleep disturbances, psychological distress related to appearance, impaired social and occupationalfunctioning, dysregulation of the hypothalamic-pituitary-adrenal axis, and neuroinflammation. Further researchis needed to validate these proposed mechanisms empirically. For effective suicide prevention in dermatology patients, it is essential not only to treat the skin condition itself but also to assess and support mental health, screen for suicide risk, and ensure collaboration with mental health professionals.

Objectives: This study examined the influence of adult attention-deficit/hyperactivity disorder (ADHD) and insomnia on the risk of unintentional minor musculoskeletal injuries (UMMI). Methods: A prospective observational study was carried out in a single unit of the army in South Korea. One hundred and seventy-seven subjects participated in the study. The Adult ADHD SelfReport Scale (ASRS-v1.1) and Insomnia Severity Index (ISI) was used to screen. The risk of UMMI during one-week winter ranger training was investigated. Results: All subjects were male and aged 21.75 (standard deviation 1.5). Approximately 9.6% of subjects had clinically relevant adult ADHD symptoms. Subjects with ADHD had a higher stress index and higher rates of insomnia than those without symptoms. After adjusting for age, rank, service months, obesity, history of UMMI, sleep time, and risk of the task, the ADHD group was 4.90 times more likely to have UMMI than the control group. Insomnia increased the risk of UMMI 8.14 fold. Conclusion These results suggest that an evaluation and intervention for adult ADHD and insomnia should be made in people engaged in other tasks that may result in UMMI.
