Summary
Allergic contact dermatitis is common in healthcare workers (HCWs). This study identified rubber chemicals, fragrances, and preservatives as key allergens in New Zealand HCWs, particularly those with hand dermatitis.
Area of Science:
- Occupational dermatology
- Immunology
Background:
- Allergic contact dermatitis (ACD) is a prevalent occupational skin condition affecting healthcare professionals.
- Identifying specific allergens is crucial for managing ACD in this population.
Purpose of the Study:
- To investigate the common causes of allergic contact dermatitis among healthcare workers in New Zealand.
- To determine the relevance of specific allergens identified through patch testing.
Main Methods:
- A retrospective analysis of healthcare workers (HCWs) who underwent patch testing between July 2008 and January 2020.
- Data included demographics, occupation, patch test results, and diagnoses.
Main Results:
- Out of 837 patients, 67 were HCWs, predominantly nurses. Hand dermatitis was the most common presentation (49%).
- 57% of HCWs had at least one positive patch test reaction, with 28% being currently relevant.
- The most frequent relevant allergens included rubber accelerators (16), fragrances (11), preservatives (10), and corticosteroids (6).
Conclusions:
- Rubber chemicals, fragrances, preservatives, and topical corticosteroids are significant allergens for HCWs.
- Patch testing for HCWs, especially those with hand dermatitis, should include a rubber series to identify relevant allergens effectively.

01:22PPE Use in Healthcare Settings I: Donning
1.4K
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.

01:10PPE Use in Healthcare Settings II: Doffing
1.2K
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.

01:30Hypersensitivities
2.0K
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...

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

01:27Allergic Drug Reactions
1.1K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...
