Increased Body Temperature

Increased Body Temperature

A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Hyperthyroidism I: Introduction

Hyperthyroidism I: Introduction

Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...

背景:

悪性高温症 (MH) は,高代謝危機を引き起こす薬剤遺伝疾患である.
臨床的表れには,筋肉の硬直性,酸性症,低心力症,高熱症が含まれています.
この状態は,サルコプラズマ網膜から異常なカルシウムが放出され,しばしばライオノジン受容体遺伝子 (RYR1) の遺伝的変異によるものです.

研究の目的:

悪性高温症 (MH) 感受性におけるライオノジン受容体 (RYR1) 遺伝子変異の役割を調査する.
MHの診断ツールとして変異分析を探求する.

主な方法:

悪性高温症 (MH) とライオノジン受容体 (RYR1) 遺伝子変異に関する既存の研究のレビュー.
現在のゴールドスタンダード診断テスト (カフェイン・ハロタン・コントラクトーラ・テスト) の限界についての議論.

主要な成果:

ライアノジン受容体 (RYR1) 変異は,北米のMHに敏感な個人の少なくとも25%で特定されています.
米国では,RYR1遺伝子の変異分析が利用可能になりました.

結論:

RYR1遺伝子変異分析は,悪性高温症 (MH) 感受性を診断するための貴重なツールとして浮上しています.
遺伝子検査は,侵襲的な診断方法に対する有望な代替手段または補助手段を提供します.
