まとめ

意図的な自己中毒は若者の自殺未遂の大きなリスクです. この研究では精神疾患の診断や性的虐待や自傷行為が幼児の再発中毒のリスクを高めることが分かりました

科学分野:

小児の緊急医療
青少年精神科
毒理学について

背景:

自殺未遂の主な方法は自殺未遂の意図的な自己中毒であり,自殺未遂の頻度が増加し,死亡リスクも高い.
小児の緊急治療室では,若者の意図的な自己中毒の事例が頻繁に発生します.
再発の要因を理解することは効果的な予防戦略に不可欠です

研究の目的:

小児患者の意図的な自己中毒に対する緊急治療室 (ED) の遭遇を記述する.
若者の自己中毒の再発に伴う人口統計学的および臨床的要因を特定する.

主な方法:

6~17歳の小児性勃起を呈した患者の遡及的横断研究.
2020年3月から2023年3月まで収集されたデータ,摂取,過剰摂取,または自殺未遂の訪問理由と請求コードを含む.
再発に関連する要因を特定するために使用される多変数ロジスティック回帰.

主要な成果:

535人の患者との出会いを分析した.
患者の12.7%は自殺のために診察を受けた.
再発に関連する要因には,既存の精神病診断 (aOR 17.03),性的虐待歴 (aOR 1.96) および自己傷害行為歴 (aOR 3.00) が含まれていた.

結論:

若者の意図的な自己中毒は深刻な病気を引き起こし半数近くが医療介入を要し 1/4が入院を要する
8人に1人に自己中毒が再発し,ターゲットを絞った介入の必要性を強調した.
特定の危険因子を特定することで青少年における再発的な意図的な自己中毒に対する予防プログラムの策定に役立ちます

In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain.

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
