概括
金属过敏是一种经过梯形甲手腕假肢修改后未被诊断出来的并发症. 早期的放射性迹象,如骨质解脱,然后是炎症,表明金属过敏.
科学领域:
- 整形外科手术 整形外科手术
- 植入物材料科学 植入物材料科学
- 免疫学 免疫学 免疫学
背景情况:
- 金属过敏是一种未被认可的骨科植入物并发症,特别影响手.
- 梯形甲手腕 (TMC) 关节置换术的增长率需要更好地了解与植入物相关的并发症.
- 在TMC联合修订中,对金属过敏的研究有限.
研究的目的:
- 评估TMC假肢修改中金属过敏的发生率.
- 为了确定放射性变化的特征序列,表明金属过敏.
- 为了区分金属过敏与假肢失败的其他原因.
主要方法:
- 37名接受TMC假肢修改的患者的单中心回顾性研究 (2014年1月 - 2023年11月).
- 分析临床数据和手术后X射线,用于无法解释的假肢失败的患者.
- 包括对金属过敏的疑似病例进行过敏测试.
主要成果:
- 8名患者 (21%) 通过过敏测试被诊断出金属过敏.
- 在植入后15天至1个月内,在第一个手指骨中观察到一贯的甲状腺骨解模式.
- 患者通常经历了一段无症状的间隔,随后出现炎症和骨质溶解的放射性迹象.
结论:
- 早期骨质溶解和随后的临床恶化的可重现模式强烈表明TMC关节整形术后的金属过敏性.
- 早期识别放射性骨质溶解对于诊断金属过敏至关重要.
- 必须考虑和排除感染性原因,即使有暗示金属过敏的迹象.

Drug Toxicity: Allergic Reactions
223
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Hypersensitivity Reactions: Immune-Complex Reactions
287
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum...
