Chronic Kidney Disease II: Clinical Manifestations

520
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Coronary Artery Disease III: Clinical Manifestations

299
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Endocarditis II: Clinical Features of Infective Endocarditis

364
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Heart Failure III: Clinical Manifestations

436
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

652
Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.

Hypertension III: Clinical Manifestations and Diagnostic Studies01:30

Hypertension III: Clinical Manifestations and Diagnostic Studies

437
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

科学分野:

  • 神経科学;神経学

背景:

  • 眼瞼開口失行(AEO)およびよりまれな眼瞼閉鎖失行(AEC)を含む眼瞼失行は、随意的な眼瞼運動の困難を伴う。;皮質基底核症候群(CBS)は、皮質基底核変性症(CBD)のような原発性タウオパチーと関連することが多い進行性の神経変性疾患である。;AEOはCBSで認識されているが、AECはまれであり、独自の臨床的課題を提示する。

研究 の 目的:

  • 眼瞼閉鎖失行(AEC)を呈する皮質基底核症候群(CBS)の症例を報告する。;CBSの文脈におけるAECの潜在的な基礎病態生理および神経解剖学的相関について議論する。;神経変性疾患におけるまれな運動障害の理解に貢献する。

主な方法:

  • 言語障害、パーキンソニズム、失行症を含む5年間の神経症状の病歴を持つ72歳女性の詳細な症例報告。;神経学的検査では、反射性瞬目(reflex blinking)を保持したまま、言語失行および眼瞼閉鎖失行(AEC)が明らかになった。;脳MRIでは軽度の両側前頭葉および右側萎縮が示された。DaTスキャンは陰性であった。

主要な成果:

  • 患者は皮質基底核症候群(CBS)の可能性の基準を満たし、臨床症状と萎縮パターンは皮質基底核変性症(CBD)のような4Rタウオパチーを示唆していた。;眼瞼閉鎖失行(AEC)は、他のCBS症状と並行して現れる顕著な特徴であった。;神経心理学的検査では、言語および運動制御における特定の障害を伴う、全般的な認知障害が示された。

結論:

  • 眼瞼閉鎖失行(AEC)は、皮質基底核変性症(CBD)のような原発性タウオパチーを含む神経変性疾患に現れる可能性のあるまれな状態である。;この所見は、AECと4Rタウオパチーとの関連を支持し、島皮質および前頭頭頂ネットワークの関与の可能性を示唆する。;神経変性疾患におけるAECの病変ネットワークとその言語ネットワークとの関係を解明するためには、さらなる研究が必要である。
