Summary
This study established updated diagnostic criteria for atopic dermatitis (AD) in Koreans, simplifying diagnosis for clinical practice. The new criteria include key symptoms and diagnostic aids for better patient care.
Area of Science:
- Dermatology
- Clinical Immunology
- Epidemiology
Background:
- The Korean Atopic Dermatitis Association (KADA) previously established diagnostic criteria for atopic dermatitis (AD) in 2006.
- Recent advancements necessitate simplified and more practical diagnostic approaches for AD.
Purpose of the Study:
- To develop and share a consensus on updated diagnostic criteria for atopic dermatitis (AD) in the Korean population.
- To incorporate recent evidence and clinical experience into AD diagnosis.
Main Methods:
- Literature search of MEDLINE and Cochrane Database of Systematic Reviews to construct a questionnaire.
- A modified Delphi method involving 3 rounds of email questionnaires for consensus building.
- Expert consensus achieved through 3 rounds of voting by 54 KADA council members.
Main Results:
- Core diagnostic criteria for AD identified as pruritus, age-specific eczema patterns, and chronic/relapsing history.
- Key diagnostic aids for AD include xerosis, IgE reactivity, and specific eczema locations (hand-foot, nipple).
- Additional diagnostic considerations include perioral/periorbital/periauricular changes, perifollicular accentuation, and atopic history.
Conclusions:
- The study successfully streamlined and updated the diagnostic criteria for atopic dermatitis (AD) in Korea.
- The revised criteria are more practical for application in real-world clinical settings.
- This consensus aims to improve the accuracy and efficiency of AD diagnosis in Korean patients.

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:13Asthma III: Clinical Manifestations
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
