Skin Diseases and Disorders

6.0K
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...

Drug Toxicity: Allergic Reactions

80
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...

Defenses Against Pathogens and Herbivores

29.8K
Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Hypersensitivities01:30

Hypersensitivities

8.0K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

    Area of Science:

    • Dermatology
    • Allergology
    • Botany

    Background:

    • Plant-induced contact dermatitis is a significant dermatological concern.
    • Identifying specific plant allergens is crucial for effective management and prevention.

    Purpose of the Study:

    • To investigate the prevalence and specific plant triggers of contact dermatitis in a suspected patient cohort.
    • To identify common plant allergens responsible for allergic contact dermatitis.

    Main Methods:

    • Forty-seven patients with suspected plant dermatitis underwent patch testing.
    • Testing utilized extracts from various suspected allergenic plants.

    Main Results:

    • Twenty-six patients (55.3%) showed positive patch tests to one or more plant antigens.
    • Parthenium sensitivity was identified in nine cases.
    • Other significant plant allergens included Trianthema monogyna, Carissa carandus, Amaranthus species, Euphorbia species, Salvia plebia, Lantana camera, and Pennisetum typhoides.

    Conclusions:

    • Several plant species are implicated in causing allergic contact dermatitis, with Parthenium being a notable allergen.
    • Rural populations are frequently affected, and symptom exacerbation during the rainy season suggests environmental factors.
    • Further research into plant-specific dermatitis is warranted.
