概括
与IgG4相关的缺血炎 (IgG4-RH) 可以独立于IgG4相关的疾病 (IgG4-RD) 发生,并且不成比例地影响年轻女性. 仅仅基因病理学对诊断是不够的,需要临床和放射学相关性.
科学领域:
- 内分泌学 在内分泌学.
- 免疫学 免疫学 免疫学
- 病理学 病理学 病理学
背景情况:
- 免疫球蛋白G4相关的低细胞炎 (IgG4-RH) 越来越多地被认为是IgG4相关疾病 (IgG4-RD) 的表现.
- 孤立的IgG4-RH病例,缺乏典型的IgG4-RD特征,以及IgG4透到其他垂体病理中,导致诊断挑战.
研究的目的:
- 更新对脑垂体IgG4炎症变化的理解,重点关注孤立的IgG4-RH.
- 分析2014年至2025年之间最近发表的IgG4-RH病例.
主要方法:
- 2014年至2025年IgG4-RH详细病例报告和系列的文献综述.
- 将病例分为孤立的IgG4-RH,IgG4-RH相关的IgG4-RD,以及IgG4透在其他垂体病理中的病例.
- 对于IgG4炎症透的定义:>10个IgG4阳性细胞/高功率场和/或>40%的IgG4血细胞具有史托里形纤维化.
主要成果:
- 自2014年以来,报告了19个孤立的IgG4-RH病例和12个IgG4-RH相关的IgG4-RD病例.
- 与IgG4-RD相关病例 (平均年龄60岁) 相比,孤立的IgG4-RH主要影响年轻女性 (3.8:1比,平均年龄39岁).
- 14例病例显示IgG4透到其他垂体病变中,特别是拉特克裂囊.
结论:
- 在各种垂体病理中发生IgG4炎症透,而不仅仅是IgG4-RD.
- 孤立的IgG4-RH,影响年轻女性,可能代表一个独特的实体,可能是淋巴细胞性下体炎,而不是IgG4-RD的形式.
- 下垂体IgG4透物需要综合的病原体学,临床和放射学评估来准确诊断.

01:17The Pituitary Gland
9.8K
The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.

01:27Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
2.5K
The sympathetic pathways of the collateral ganglia and adrenal medulla serve unique but interconnected roles in the sympathetic response.
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...
