まとめ
免疫能力のある患者におけるまれなサルモネラ性甲状腺膿瘍が、非外科的処置で首尾よく治療されました。この症例は、特に胃腸疾患の既往歴のある患者において、甲状腺膿瘍の鑑別診断としてサルモネラを考慮することの重要性を強調しており、迅速な診断と治療を導きます。
科学分野:
- 内分泌学
- 感染症
- 外科技術
背景:
- 甲状腺膿瘍は、甲状腺の感染に対する固有の抵抗性のため、まれです。
- サルモネラ属菌のようなグラム陰性菌は、通常、血行性播種から生じる甲状腺膿瘍のまれな原因です。
研究 の 目的:
- 免疫能力のある個人におけるサルモネラ性甲状腺膿瘍のユニークな症例を報告すること。
- 胃腸疾患の既往歴のある患者、特に甲状腺膿瘍の鑑別診断においてサルモネラを考慮することの重要性を強調すること。
主な方法:
- 首の腫れと嚥下困難を呈した41歳の産後授乳中の女性の症例研究。
- 診断手順には、画像検査と培養を伴う微細針吸引(FNA)が含まれていました。
- 治療には、培養特異的抗菌薬、超音波ガイド下針吸引ドレナージ、およびβ遮断薬が含まれていました。
主要な成果:
- 微細針吸引により、甲状腺膿瘍からサルモネラ属菌が同定されました。
- 患者は初期の抗生物質治療にもかかわらず、再発性の症状を経験しました。
- 手術を回避し、抗生物質、ドレナージ、およびβ遮断薬の組み合わせによって非外科的管理が達成されました。
結論:
- この症例は、免疫能力のある宿主における血行性播種に由来するサルモネラ性甲状腺膿瘍のまれなインスタンスを強調しています。
- 臨床医は、特に胃腸感染症の既往のある患者において、首の腫瘤または嚥下困難を呈する患者の鑑別診断においてサルモネラ性甲状腺膿瘍を考慮する必要があります。
- FNAによる迅速な診断と標的化された抗菌療法は、適切なドレナージとともに、良好な転帰と外科的介入の予防に不可欠です。

Synthesis and Regulation of Thyroid Hormones
7.0K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

The Thyroid Gland
6.5K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Functions of Thyroid Hormones
4.9K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Gastritis-II: Pathophysiology
1.1K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Receptor-mediated Endocytosis
7.4K
Receptor-mediated endocytosis is when bulk amounts of specific molecules are imported into a cell after binding to cell surface receptors. The molecules bound to these receptors are taken into the cell through inward folding of the cell surface membrane, which is eventually pinched off into a vesicle within the cell. Structural proteins, such as clathrin, coat the budding vesicle.

Skeleton and Calcium Homeostasis
5.7K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
