まとめ
血管奇形に対するブレオマイシン電気硬化療法(BEST)は皮膚の色素沈着を引き起こす可能性があり、特に六角形電極および高用量(≥0.10 mg/kg)で顕著である。この副作用を最小限に抑えるには、電極の選択と慎重な投与量が重要である。
科学分野:
- 血管外科、皮膚科、インターベンショナルラジオロジー
背景:
- 硬化療法は、低流速血管奇形の標準治療です。ブレオマイシン電気硬化療法(BEST)は、再発性病変に有望です。皮膚の色素沈着は、BESTの既知の有害事象です。
研究 の 目的:
- BEST後の皮膚の色素沈着の発生率とその関連要因を分析すること。既存のブレオマイシン誘発性色素沈着に関する文献との比較。
主な方法:
- 21ヶ月間にわたる72人の患者(80回の処置)の後ろ向き分析。色素沈着の臨床的および写真による文書化。電極の種類やブレオマイシン投与量(mg/kg)を含む治療パラメータの分析。
主要な成果:
- リンパ管腫(LM)では4/7、静脈奇形(VM)では20/44、静脈リンパ管奇形(VLM)では16/29に色素沈着が発生しました。六角形電極(58.9%)は、NFDおよびVGDと比較して発生率が高かったです。静脈内投与(61.8%)は、病変内投与(41.3%)よりも頻繁でした。ブレオマイシン0.10 mg/kg以上の投与量閾値は、色素沈着のリスクを増加させました(相対リスク 2.30)。
結論:
- BEST後の皮膚の色素沈着は頻繁に発生し、電極の形状や投与量の影響を受けます。六角形電極と高用量(≥0.10 mg/kg)のブレオマイシンは、リスクの増加と関連しています。電極の選択と投与量の最小化により、美容的結果を改善できます。

Gene Evolution - Fast or Slow?
8.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Vascular Spasm
3.7K
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last...

Overview of the Vascular System
3.6K
The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...

Vascular Resistance

Vascular resistance is a critical concept in understanding blood flow dynamics in the circulatory system. It refers to the resistance that blood encounters as it flows through the blood vessels. This resistance is a key factor in determining blood pressure and cardiac workload.
The primary determinants of vascular resistance are vessel diameter, blood viscosity, and vessel length. Among these, vessel diameter plays the most significant role due to the fourth power relationship described by...
