Asthma: Pathogenesis and Management01:20

Asthma: Pathogenesis and Management

1.1K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

3.1K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Changes in Skin Color: Clinical Perspectives

3.2K
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...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

1.6K
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Skin Diseases and Disorders

5.0K
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...

Area of Science:

  • Dermatology and Immunology

Background:

  • Atopic dermatitis (AD) presents a substantial disease burden, significantly impairing quality of life.
  • AD is associated with comorbidities such as mental disorders and cardiovascular diseases.
  • Key factors influencing AD pathophysiology include race, environment, skin barrier dysfunction, immune dysregulation, and microbiome alterations.

Purpose of the Study:

  • To summarize the multifaceted pathophysiology of atopic dermatitis.
  • To highlight the role of various immune cells and cytokines in AD.
  • To discuss the implications of microbial dysbiosis and antimicrobial peptide deficiency.

Main Methods:

  • Review of existing literature on atopic dermatitis.
  • Analysis of immunological and microbiological factors contributing to AD.
  • Examination of the impact of AD on patient quality of life and associated conditions.

Main Results:

  • Immune cells like Th2, Th17, Th22, and type 2 innate lymphoid cells play crucial roles in AD.
  • Cytokines from these cells disrupt epidermal differentiation and skin barrier function.
  • Microbial dysbiosis and reduced antimicrobial peptides can lead to Staphylococcus aureus infections in AD patients.

Conclusions:

  • Emerging therapies targeting specific immune pathways offer new hope for managing moderate-to-severe atopic dermatitis.
  • Understanding the complex interplay of genetic, environmental, immune, and microbial factors is crucial for AD management.
  • New drug development focuses on addressing the underlying immune dysregulation in AD.
