概括
罕见的自身免疫性皮肤疾病,如 discoid lupus erythematosus 和 bullous pemphigoid,可以在疹病毒 (HZ) 感染后出现,这种现象被称为狼的同位素反应. 持续的HZ后皮疹需要对这些自身免疫原因进行调查.
科学领域:
- 皮肤病学 皮肤病学
- 免疫学 免疫学 免疫学
- 传染性疾病 传染性疾病
背景情况:
- 带状疹 (HZ) 通常会在没有持久影响的情况下消失.
- 很少情况下,慢性皮肤疾病可能会在先前的HZ部位出现,称为同位素反应.
- 这涉及一个新的,无关的皮肤疾病出现在HZ受影响的区域.
研究的目的:
- 报告两例自身免疫性皮肤病例 (性红斑狼和性类狼) 作为HZ后的同位素反应.
- 探索这些事件背后的潜在病理生理机制.
主要方法:
- 两名患有HZ病史的患者呈现出局部,持久的皮肤病变.
- 诊断方法包括临床评估,组织病理学,免疫学测试和PCR.
- 排除了病毒的持续性,并证实了自身免疫病因.
主要成果:
- 案例1:一个患有SLE的患者在HZ后发展出 discoid lupus erythematosus (DLE),对免疫抑制和局部类固醇有反应.
- 案例2:一个患者在HZ后发展出牛性皮虫 (BP),对强烈的局部皮质类固醇有反应.
- 这两种病例都显示了局部化的自身免疫性皮肤疾病,局部化到之前的HZ皮肤病.
结论:
- 这些案例凸显了识别狼的同位素反应的重要性.
- 自身免疫性皮肤疾病可以在先前HZ感染的部位表现出来.
- 临床医生应该怀疑持续的后HZ爆发的自身免疫原因,特别是在那些有现有的自身免疫疾病的人群中.

Local Anesthetics: Differential Sensitivity of Nerve Fibers
933
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Immunological Memory
5.0K
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Immune Response Against Viral Pathogens
917
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Cells of the Adaptive Immune Response
4.1K
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
