Insights

Approximately one-third of Turkish schoolchildren experience allergic disease symptoms annually. This study highlights regional variations and diagnostic challenges in childhood allergies, emphasizing the need for objective data collection.

Area of Science:

  • Pediatric Allergy and Immunology
  • Epidemiology
  • Public Health

Background:

  • Limited standardized data on childhood allergic diseases in Turkey necessitates multicenter studies.
  • Objective tools are crucial to enhance the validity and reliability of allergy research in schoolchildren.
  • Previous research highlights the need for better diagnostic and treatment strategies for pediatric allergic conditions.

Purpose of the Study:

  • To determine the prevalence of allergic diseases among elementary schoolchildren in Turkey.
  • To investigate regional variations in allergic disease symptoms and objective signs.
  • To assess the impact of allergic diseases on school absenteeism.

Main Methods:

  • Utilized International Study of Asthma and Allergies in Children (ISAAC) Phase II tools for data collection.
  • Surveyed 6963 children aged 9-11 years across 5 major Turkish cities.
  • Employed parental reports and objective diagnostic tools to assess allergic conditions.

Main Results:

  • 35% of surveyed children reported at least one allergic disease symptom in the past year.
  • Prevalence rates: wheezing (15.8%), rhinoconjunctivitis (23.5%), eczema (8.1%), atopy (18.9%), flexural dermatitis (3.6%), bronchial hyperreactivity (24.2%).
  • Significant interregional variations in symptom and objective sign prevalence were observed; 34.2% of children with asthma/allergic rhinitis experienced school absence.

Conclusions:

  • About one-third of Turkish elementary schoolchildren exhibit symptoms consistent with allergic diseases.
  • Interregional disparities in allergic disease prevalence may be linked to environmental factors.
  • Challenges persist in the timely and accurate diagnosis and management of allergic diseases in children.

Asthma I: Introduction

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...

Overview
Allergic Reactions: Anaphylaxis01:30

Allergic Reactions: Anaphylaxis

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, heparin),...

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Asthma-II: Pathophysiology and Classification01:26

Asthma-II: Pathophysiology and Classification

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-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...
