まとめ
ステロイド注射は,縮性テンノシノビチス (Flexor Tendon Sheat Ganglions,FTSG) の発生リスクを増加させる可能性があります. 注射は症状を緩和しますが,非注射治療と比較してFTSGの発生率が高くなります.
科学分野:
- 整形外科
- 手の手術
- 筋骨格画像検査
背景:
- 柔らかいのシートギャングリオン (FTSG) の形成の正確なメカニズムは完全に理解されていません.
- ステロイドの注射は,FTSGの病因因子であると疑われる.
- この研究では,ステロイド注射とFTSGの発症の関連性について研究しています.
研究 の 目的:
- コルチコステロイド注射後,柔らかいの蓋のギャングリオン (FTSG) の形成のリスクを評価する.
- ステロイド注射を受けた患者と注射を受けなかった患者におけるFTSGの発生率を比較する.
主な方法:
- 展望的なコホート研究には,縮小性屈折性テンソシノビチスの患者114人が参加した.
- 参加者は最初の超音波検査を受けたが,FTSGを患っている人は除外された.
- 投薬群は柔らかいの殻にステロイドを注入したが,対照群はそうしなかった.
主要な成果:
- ステロイド注射群のFTSGの発生率は,対照群 (4. 5%) に比べて有意に高かった.
- グループ間で有意なリスク差 (0. 33) が観察された (p < 0. 01).
- 症状の改善は注射群 (93%) と対照群 (45%) で著しく増加した (p < 0. 01).
結論:
- ステロイド注射は,潜在的にマイクロパンクチャーの原因で,柔らかいの蓋のギャングリオン形成に寄与する可能性があります.
- FTSGの発症におけるその役割については,さらなる調査が必要である.
- ステロイド注射によるギャングリア形成の臨床的意義については,さらなる研究が必要である.

Sympathetic Pathways: Sympathetic Chain Ganglia
3.4K
The sympathetic chain ganglia, also known as the sympathetic trunk ganglia or paravertebral ganglia, are a series of ganglia located bilaterally on either side of the spinal column. These ganglia serve as relay stations for the sympathetic nervous system. Preganglionic neurons originating in the spinal cord project their axons to the sympathetic chain ganglia. Within the ganglia, these preganglionic fibers synapse with postganglionic neurons.The postganglionic neurons of the sympathetic trunk...

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
1.5K
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.

Peripheral Nervous System: Ganglia and Nerves
2.6K
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

Anatomy of the Adrenal Glands
2.6K
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.
