Summary
Identifying eczema flare triggers is crucial for managing this common childhood condition. This study highlights environmental factors like dust, pets, and clothing, plus new findings on shampoo use in cold weather and combined triggers.
Area of Science:
- Dermatology
- Pediatric Health
- Environmental Health
Background:
- Eczema (atopic dermatitis) is a significant global public health concern, particularly in children.
- Identifying specific triggers for eczema flares remains a challenge, limiting effective management strategies.
- Existing research offers limited direct evidence on the environmental and lifestyle factors contributing to disease exacerbation.
Purpose of the Study:
- To systematically review and prospectively investigate environmental factors associated with eczema flare-ups in children.
- To provide evidence-based insights for families to potentially reduce disease flares.
- To explore the role of combined environmental exposures in eczema exacerbation.
Main Methods:
- Conducted a systematic review of published literature on eczema flare triggers.
- Performed a prospective cohort study focusing on environmental exposures and eczema flares.
- Collected data on factors including diet, environmental allergens, clothing, personal care products, and weather conditions.
Main Results:
- Systematic review suggested foodstuffs, dust, pets, seasonal changes, stress, and irritants as potential triggers.
- Prospective study identified associations between nylon clothing, dust, unfamiliar pets, sweating, and shampoo with eczema flares.
- Novel findings include increased shampoo effect in cold weather and combined environmental factors exacerbating eczema, supporting a multifactorial disease model.
Conclusions:
- Environmental factors, including specific clothing materials, dust, pets, and personal care products like shampoo, play a significant role in eczema flares.
- The impact of certain triggers, such as shampoo, can be influenced by environmental conditions like temperature.
- Eczema exacerbation is likely driven by a combination of factors, necessitating a comprehensive approach to trigger identification and management.

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,...
01:23Skin 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...

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...
01:27Acne 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...
01:19Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
01:24Asthma-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:
