Summary
Atopic dermatitis (AD) can increase allergy risk from topical products and metals. However, AD
Area of Science:
- Immunodermatology
- Allergology
Background:
- Atopic dermatitis (AD) and allergic contact dermatitis (ACD) are common immune-mediated skin diseases.
- Understanding their interrelationship is crucial for managing patient susceptibility.
Purpose of the Study:
- To investigate the influence of atopic dermatitis on the risk of developing contact sensitization and allergic contact dermatitis.
- To explore the complex interplay between AD and ACD.
Main Methods:
- Review of recent investigations and clinical observations.
- Analysis of factors influencing sensitization in AD patients.
Main Results:
- Topical product use in AD increases sensitization to fragrances and emollient ingredients.
- Increased prevalence of metal allergy in AD patients, potentially due to impaired metal chelation.
- The T-helper cell 2 bias in AD may paradoxically reduce contact sensitization risk compared to controls.
Conclusions:
- Multiple factors influence the association between atopic dermatitis and contact sensitization.
- Clinical management of AD requires appreciation of these complex interactions.

209
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...

01:28Asthma I: Introduction
112
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

4.7K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

01:26Factors Affecting the Risk of Infection
14.1K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
