Allergic Reactions: Anaphylaxis01:30

Allergic Reactions: Anaphylaxis

92
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,...

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...

Local Anesthetics: Adverse Effects

915
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Allergic Drug Reactions

1.5K
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...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

2.1K
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Summary
This summary is machine-generated.

Dental adhesives containing acrylates can cause allergic reactions, leading to oral stomatitis. Patch testing identified acrylate in adhesives as the cause of a patient's hypersensitivity reaction, highlighting a potential rise in allergic stomatitis.

Area of Science:

  • Dentistry
  • Allergology
  • Dermatology

Background:

  • Oral allergic reactions, specifically stomatitis, are increasingly reported.
  • Type IV hypersensitivity reactions are a common cause of contact dermatitis.
  • Dental materials are potential allergens in the oral cavity.

Purpose of the Study:

  • To report a case of oral stomatitis caused by a type IV hypersensitivity reaction.
  • To identify the causative agent in dental adhesives responsible for the allergic reaction.
  • To discuss the role of acrylates in dental materials as a cause of hypersensitivity.

Main Methods:

  • Diagnosis of oral stomatitis via clinical presentation.
  • Identification of the allergen through patch testing with dental adhesives.
  • Chemical analysis of dental adhesives to determine allergenic components.

Main Results:

  • Patch testing confirmed a type IV hypersensitivity reaction to specific dental adhesives.
  • Both tested adhesives contained acrylate, a known allergen.
  • Acrylate is increasingly implicated in hypersensitivity reactions in scientific literature.

Conclusions:

  • Common dental adhesives, particularly those containing acrylates, can cause type IV hypersensitivity reactions manifesting as oral stomatitis.
  • While metals are known allergens, other contactants like acrylates in dental adhesives should be considered.
  • The rising incidence of allergic stomatitis may be linked to the use of modern 'all-in-one' dental adhesives.
