Skin Diseases and Disorders

5.4K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

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.

Autoimmune Disorders01:29

Autoimmune Disorders

2.4K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

3.7K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Skin Cancer01:30

Skin Cancer

5.2K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Graves' Disease I: Introduction01:28

Graves' Disease I: Introduction

23
Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence...

Summary
This summary is machine-generated.

Vitiligo is an acquired skin disorder affecting melanocytes, which originate from the neural crest. This condition involves systemic melanocyte loss, often linked to autoimmune diseases, presenting a common depigmentation phenotype.

Area of Science:

  • Dermatology
  • Immunology
  • Cell Biology

Background:

  • Vitiligo is an acquired depigmentary skin disorder with unknown causes.
  • Melanocytes, originating from neural crest cells, are found throughout the body, not just the skin.
  • Vitiligo involves not only skin melanocytes but also a systemic involvement of these cells.

Purpose of the Study:

  • To explore the systemic nature of vitiligo beyond skin manifestations.
  • To understand the diverse etiologies and pathogeneses of vitiligo.
  • To highlight the common phenotype of melanocyte loss in vitiligo.

Main Methods:

  • Review of existing literature on vitiligo.
  • Analysis of melanocyte biology and distribution.
  • Correlation of vitiligo subtypes with associated diseases, particularly autoimmune conditions.

Main Results:

  • Vitiligo is characterized by the loss of melanocytes and/or their products.
  • Nonsegmental vitiligo is frequently associated with autoimmune diseases.
  • The common phenotype of vitiligo indicates a systemic process affecting melanocytes.

Conclusions:

  • Vitiligo is a systemic disorder impacting melanocytes throughout the body.
  • Understanding the diverse causes of vitiligo is crucial for effective management.
  • The depigmentation phenotype signifies a broader systemic involvement of melanocytes.
