Changes in Skin Color: Clinical Perspectives

3.6K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

954
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Overview of Systemic Arteries

2.6K
The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the...

Area of Science:

  • Vascular Medicine
  • Dermatology

Background:

  • Acrocyanosis is a functional peripheral vascular disorder.
  • Characterized by bluish skin and mucous membrane discoloration due to diminished oxyhemoglobin.
  • May stem from central or local tissue oxygenation defects, presenting as a painful, episodic condition.

Purpose of the Study:

  • To describe the etiology, clinical features, and management of acrocyanosis.
  • To clarify the underlying pathophysiology, emphasizing vasospasm.
  • To outline current treatment strategies, focusing on conservative measures.

Main Methods:

  • Review of existing literature on acrocyanosis.
  • Analysis of clinical presentation and diagnostic criteria.
  • Evaluation of reported management approaches.

Main Results:

  • Acrocyanosis can be primary or secondary to various conditions.
  • Chronic vasospasm of small cutaneous arteries is the prevailing hypothesis.
  • Clinical features include coolness and violaceous discoloration of extremities, ears, nose, and lips, often exacerbated by cold.

Conclusions:

  • There is no standard curative treatment for acrocyanosis.
  • Management primarily involves lifestyle modifications, including cold avoidance, and patient reassurance.
  • Mild cases do not require drug treatment.
