Skin Diseases and Disorders

5.1K
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...

Hand hygiene01:23

Hand hygiene

5.2K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

PPE Use in Healthcare Settings II: Doffing01:10

PPE Use in Healthcare Settings II: Doffing

1.6K
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.

Burn Injuries01:22

Burn Injuries

4.4K
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...

Papillary Dermis01:11

Papillary Dermis

5.8K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Summary

Occupational allergic contact dermatitis affects nearly 9% of pizza makers, with diallyl disulfide and ammonium persulfate identified as key allergens. Patch testing is crucial for diagnosing hand eczema in food handlers.

Area of Science:

  • Dermatology
  • Occupational Health
  • Food Science

Background:

  • Contact eczema is common in food handlers due to occupational exposure to food ingredients.
  • Pizza making is a prevalent occupation globally, increasing the risk of food-related skin conditions.

Purpose of the Study:

  • To investigate the prevalence and causes of contact dermatitis among pizza makers in Naples.
  • To identify specific allergens responsible for occupational hand eczema in this cohort.

Main Methods:

  • An observational study involving 45 pizza makers was conducted.
  • Data collected via questionnaires on allergy history and work conditions.
  • Dermatological examinations and patch testing with standard and custom series were performed.

Main Results:

  • 13.3% of pizza makers reported hand eczema; 8.9% had occupational allergic contact dermatitis.
  • Diallyl disulfide and ammonium persulfate were identified as the primary causative agents.
  • Patch testing proved effective in identifying allergens.

Conclusions:

  • Patch testing is valuable for diagnosing hand contact dermatitis in pizza makers and food handlers.
  • A specialized series of haptens is recommended for this occupational group.
  • Early identification and management of occupational skin allergies are essential.
