Drug Toxicity: Allergic Reactions

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...

Burn Injuries

Burn Injuries

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions

Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...

Skin Diseases and Disorders

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...

PPE Use in Healthcare Settings II: Doffing

PPE Use in Healthcare Settings II: Doffing

The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Hypersensitivities

Hypersensitivities

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...

Summary

A refinery rash outbreak linked to fire-retardant clothing (FRC) was caused by inadequate laundering. Proper washing and wearing underclothing resolved the irritant contact dermatitis in affected workers.

Area of Science:

Occupational Health
Dermatology
Textile Science

Background:

Refinery workers experienced skin eruptions including erythema, pruritus, and scaling.
Symptoms were localized to areas in contact with fire-retardant clothing (FRC).

Purpose of the Study:

To establish a link between the rash outbreak and FRC use.
To identify the specific FRC factor causing dermatitis.
To document the resolution of the outbreak.

Main Methods:

Employee questionnaires and examinations were conducted.
Patch testing and pH testing of FRC were performed.
Investigated laundering procedures for causative factors.

Main Results:

Over 100 workers reported rashes, with a unique presentation in about a third.
Hispanic and white workers showed a higher incidence compared to black workers.
The rash peaked in summer months and resolved with proper FRC laundering.

Conclusions:

The dermatitis was likely irritant contact dermatitis from improper FRC laundering.
Correct laundering procedures are crucial for prevention.
Wearing underclothing to prevent skin contact with sweat-moistened FRC is an effective measure.
