Chronic Kidney Disease II: Clinical Manifestations

516
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

295
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

358
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

430
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...

Gastroesophageal Reflux Disease II: Clinical Features and Management

647
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.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...

Hypertension III: Clinical Manifestations and Diagnostic Studies01:30

Hypertension III: Clinical Manifestations and Diagnostic Studies

433
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...

神経精神症状を呈する巨細胞性動脈炎（GCA）患者は、ステロイド副作用および自己免疫疾患の慎重な評価が必要です。自己免疫性脳炎が疑われるGCA患者は、初期検査が陰性であっても、静脈内免疫グロブリン（IVIG）が有益である可能性があります。

科学分野:

  • 神経学; 免疫学; リウマチ学

背景:

  • 巨細胞性動脈炎（GCA）は、通常コルチコステロイドで管理される自己免疫性血管炎である。; 長期コルチコステロイド療法は、著明な神経精神合併症を引き起こす可能性がある。; 本症例では、ステロイド減量中に脳症を発症したGCA患者を検討する。

研究 の 目的:

  • GCA患者における再発性神経精神症状の困難な症例を記述すること。; 意識変容を伴うGCA患者における自己免疫病因の可能性を探求すること。; 複雑なGCA症例における治療反応の診断的有用性を強調すること。

主な方法:

  • 60歳、糖尿病のGCA女性の症例研究。; メチルプレドニゾロンによる初期治療後、脳症を発症した。; 検査には、炎症マーカー、MRI、CSF分析、およびIVIG療法への反応が含まれた。

主要な成果:

  • 患者はGCAの症状を呈し、メチルプレドニゾロンで改善したが、ステロイド減量中に脳症および神経精神症状を発症した。; CRPとESRの上昇が認められ、MRIでは神経膠症が示された。尿培養で肺炎桿菌が同定され、当初はUTI誘発性脳症が示唆された。; 自己免疫性脳炎パネルは陰性であったにもかかわらず、IVIG療法により著明な臨床的改善が得られ、自己免疫成分が示唆された。

結論:

  • GCAにおける再発性神経精神症状は、診断上の課題をもたらす。; GCA患者で意識変容がある場合、ステロイド誘発性効果および自己免疫プロセスを考慮すべきである。; IVIGへの治療反応は、診断検査が陰性であっても、潜在的な自己免疫病因を示唆する。
