Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

2.2K
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

562
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Angina III: Clinical Manifestations and Assessment

446
Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

Endocarditis II: Clinical Features of Infective Endocarditis

898
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...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

833
Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Cirrhosis I: Introduction01:23

Cirrhosis I: Introduction

3
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Summary

A persistent, ring-shaped rash on the torso, accompanied by a foot infection, led to a specific dermatological diagnosis in an elderly patient. This case highlights the importance of considering co-occurring infections for accurate diagnosis.

Area of Science:

  • Dermatology
  • Medical Mycology
  • Clinical Case Study

Background:

  • Atypical presentations of common dermatological conditions can pose diagnostic challenges.
  • Persistent cutaneous lesions require thorough investigation to identify underlying causes.

Observation:

  • An 86-year-old African American woman presented with a 14-month history of an asymptomatic rash on her back and flanks.
  • Physical examination revealed annular/arcuate plaques (3-6 cm) with central clearing and a delicate trailing scale.
  • The lesions featured a slightly raised, erythematous border.

Findings:

  • The characteristic morphology of the rash, combined with a concurrent foot infection, was key to diagnosis.
  • This clinical presentation suggested a specific fungal or infectious etiology.

Implications:

  • This case underscores the diagnostic value of integrating findings from seemingly unrelated sites, such as the torso and feet.
  • Recognizing specific dermatological signs like trailing scales can aid in identifying uncommon presentations of infections.
  • Prompt and accurate diagnosis is crucial for effective management of persistent cutaneous conditions.
