Summary
The prevalence of atopic dermatitis (AD) in Tunisian schoolchildren is low at 0.65%. Family history of atopy and maternal age at birth were key associated factors for this condition.
Area of Science:
- Pediatrics
- Epidemiology
- Dermatology
Background:
- Atopic dermatitis (AD) prevalence is notably low in North Africa.
- This study focuses on the epidemiology of AD in Tunisian school children.
Purpose of the Study:
- To determine the prevalence of atopic dermatitis (AD) among schoolchildren in Sfax, Tunisia.
- To identify associated risk factors for AD in this population.
Main Methods:
- A cross-sectional survey was conducted among 1617 schoolchildren aged 5-6 years in Sfax, Tunisia.
- Diagnosis of AD followed the U.K. Working Party criteria, with examinations by a dermatologist and a parent-completed questionnaire.
- Risk factors and family history of atopy were assessed.
Main Results:
- The one-year prevalence of AD was 0.65% (10 out of 1617 children).
- The male-to-female sex ratio was 2.33:1. AD onset before age 2 occurred in 3 children.
- Strongest associated factors included a family history of atopy (parental AD) and maternal age at childbirth; breastfeeding and housing conditions did not correlate.
Conclusions:
- The prevalence of AD in Tunisian schoolchildren is low, aligning with rates in other developing countries.
- A positive family history of atopy and maternal age at birth are significant associated factors for AD.

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,...
01:28Asthma 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...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Overview
01:20Asthma: 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.
