Summary
Environmental dermatitis, including irritant and allergic contact dermatitis, is common. Recognizing clinical features and allergen distribution aids diagnosis, with patch testing confirming allergies for potentially curable skin conditions.
Area of Science:
- Dermatology
- Allergology
- Toxicology
Background:
- Environmental dermatitis, encompassing irritant and allergic contact dermatitis, represents a significant portion of dermatological cases.
- Failure to diagnose contact dermatitis can lead to prolonged or overlooked treatable conditions.
Purpose of the Study:
- To review clinical features distinguishing exogenous from endogenous dermatitis.
- To differentiate between irritant and allergic contact dermatitis.
- To provide an overview of common contact allergens and diagnostic approaches.
Main Methods:
- Review of clinical features including morphology and patient history.
- Analysis of dermatitis distribution patterns.
- Discussion of patch testing for allergy confirmation.
Main Results:
- Clinical presentation and history are key to differentiating dermatitis causes.
- Dermatitis distribution can indicate specific contact allergens.
- Patch testing remains essential for confirming allergic contact dermatitis.
Conclusions:
- Accurate diagnosis of contact dermatitis is crucial for effective management.
- Understanding clinical clues and allergen profiles improves patient outcomes.
- Patch testing is indispensable for confirming allergic contact dermatitis.

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...

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

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...

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

2.9K
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...
