Skin Diseases and Disorders01:23

Skin Diseases and Disorders

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...
Cellular Adaptation IV: Dysplasia and Metaplasia01:24

Cellular Adaptation IV: Dysplasia and Metaplasia

DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...
Accessory Structures of the Skin: Sebaceous Glands01:21

Accessory Structures of the Skin: Sebaceous Glands

A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...
Drug Toxicity: Allergic Reactions01:30

Drug Toxicity: Allergic Reactions

Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
Allergic Reactions: Anaphylaxis01:30

Allergic Reactions: Anaphylaxis

Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...

Summary
This summary is machine-generated.

Atopic eczema (AE) prevalence is rising globally, particularly in developing nations. Key factors include filaggrin mutations, IL-31 involvement in itch, and specific biomarkers, complicating diagnosis and treatment strategies.

Area of Science:

  • Dermatology
  • Immunology
  • Genetics

Background:

  • Global prevalence of atopic eczema (AE) has increased, with trends diverging between developed and developing countries.
  • Advances in understanding AE include identifying filaggrin null mutations and the role of IL-31 in pruritus.
  • Biomarkers such as thymus and activation-regulated chemokine (TARC) and proliferating-inducing ligand (APRIL) are linked to AE severity.

Purpose of the Study:

  • To review current understanding of atopic eczema pathogenesis, diagnostic challenges, and treatment implications.
  • To differentiate true atopic eczema from atopiform dermatitis (AFD).
  • To highlight the importance of allergen-specific IgE in diagnosing AE.

Main Methods:

  • Review of recent scientific literature on atopic eczema.
  • Discussion of immunocentric and corneocentric views on pathogenesis (inside-outside paradigm).
  • Analysis of diagnostic criteria for AE versus AFD.

Main Results:

  • Filaggrin null mutations are found in approximately 25% of AE patients.
  • IL-31, TARC, and APRIL are implicated in AE symptoms and severity.
  • Accurate diagnosis of AE requires identifying allergen-specific IgE.

Conclusions:

  • Diagnosing atopic eczema is complex and challenging.
  • Effective allergen elimination and lifestyle advice are contingent upon a confirmed diagnosis of true AE with allergen-specific IgE.
  • Atopiform dermatitis (AFD) requires distinct management approaches compared to true AE.
