Insights

A study found 1.8% of Korean children have chronic urticaria. Risk factors for chronic continuous urticaria include moving to a new residence and high family income.

Area of Science:

  • Pediatric Dermatology
  • Allergy and Immunology
  • Epidemiology

Background:

  • Urticaria is a common skin condition in children.
  • Data on pediatric urticaria prevalence and risk factors in Korea is limited.

Purpose of the Study:

  • To determine the prevalence of acute and chronic urticaria in Korean children.
  • To identify risk factors associated with pediatric urticaria.

Main Methods:

  • A population-based study of 4,076 Korean children (ages 4-13) from the 2015 Seongnam Atopy Project.
  • Parental questionnaires assessed urticaria characteristics; blood tests measured vitamin D, eosinophils, and IgE; skin prick tests were performed.

Main Results:

  • Prevalence: lifetime 22.5%, acute 13.9%, chronic 1.8% (continuous 0.7%, recurrent 1.1%).
  • Acute urticaria linked to allergies and parental allergy history (P<0.001).
  • Chronic continuous urticaria associated with new residence (aOR=2.38) and high family income (aOR=4.24).

Conclusions:

  • 1.8% of Korean children experience chronic urticaria.
  • Environmental and socioeconomic factors, not traditional allergy markers, are linked to chronic continuous urticaria in this pediatric population.

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Asthma-I: Introduction01:29

Asthma-I: Introduction

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...

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Peptic Ulcer Disease I: Introduction01:30

Peptic Ulcer Disease I: Introduction

Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

Hypersensitivities01:30

Hypersensitivities

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...
