まとめ
内壁切除術(MWR)は、機能性下垂体腺腫(FPA)、特にクッシング病およびプロラクチノーマに対する安全かつ効果的な外科的治療法である。このアプローチは、経験豊富なチームによって実施された場合、高い寛解率と低い合併症リスクを提供する。
科学分野:
- 神経外科; 内分泌学; 腫瘍学
背景:
- 手術は機能性下垂体腺腫(FPA)の主要な治療法である。海綿静脈洞への浸潤は、寛解率を低下させる可能性がある。内壁切除術(MWR)は成績を改善する可能性があるが、利用は少ない。
研究 の 目的:
- FPA患者におけるMWRの成績を評価すること。単一の神経外科医によるMWRの安全性と有効性を評価すること。
主な方法:
- MWRを受けた64例の成人FPA患者の後ろ向き研究。寛解は3ヶ月後のホルモン正常化によって定義された。生化学的寛解の予測因子をロジスティック回帰で分析した。
主要な成果:
- 全体の寛解率は82.8%(クッシング病92%、プロラクチノーマ87.5%、先端巨大症60%)であった。先端巨大症および腫瘍サイズの増大は、寛解の負の予測因子であった。合併症には、新たな下垂体機能低下症(9.4%)およびアルギニンバソプレシン欠乏症(20.3%)が含まれた。
結論:
- MWRは、特にクッシング病およびプロラクチノーマのFPAに対して安全かつ効果的である。高い寛解率と低い合併症は、選択された患者におけるMWRを支持する。経験豊富な多職種チームは、MWRの成功に不可欠である。

Hypothalamic-Pituitary Axis
66.2K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Hormones of the Pituitary Gland
10.4K
The small, pea-sized pituitary gland is located at the base of the brain. It is crucial in regulating various bodily functions, from growth to reproduction. The gland is divided into the anterior lobe and the posterior lobe. The secretory cell clusters in the pars distalis of the anterior pituitary lobe are controlled by hypothalamic regulators and synthesize six primary hormones.
The most abundantly secreted hormone from the anterior lobe is the growth hormone, which controls overall growth by...

The Pituitary Gland
10.8K
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.

Plant Cell Wall

The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

Predicting Reaction Outcomes
10.9K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis
107.3K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...
