Dermatitis refers to skin inflammation that causes itchy, red, swollen skin that may or may not is accompanied by blisters, oozing, and skin thickening. Dermatitis is a broad term subdivided into some types, each of which has a specific cause, symptoms, and treatment. The most common styles include Atopic dermatitis, contact dermatitis, seborrheic dermatitis, infant dermatitis, etc.
Dermatitis is standard worldwide, with children and young females most commonly affected for atopic type, while males are more widely affected for seborrheic type.
There is no cure for dermatitis; however, medications are used in acute episodes, and lifestyle changes are adopted to prevent further attacks. It is treated mainly by steroids, emollients, creams, fungi, or topical antibiotics.
The most common types of dermatitis are;
The cause of atopic dermatitis is unknown, but two theories have been proposed, one of which involves the disturbance of immune reaction, and the other suggests the abnormality of epithelial barriers. The onset of the disease usually occurs in early childhood.
The exact cause of Seborrheic dermatitis is unknown; however, genetic and environmental factors may play a role. The Malassezia yeast is also thought to be the culprit. The condition is common in infants or older adults and is prevalent in males more than females. Infants may develop yellow scales on the scalp called cradle cap and diaper rash.
Contact dermatitis can occur at any part that comes in contact with the causing agent, especially hands. The most common causing agents are nickel, chromium, poison ivy, poison oak, latex, and even sunlight (photo contact dermatitis).
The signs and symptoms specific to atopic dermatitis are:
The typical signs and symptoms of Seborrheic dermatitis include;
Signs and symptoms of contact dermatitis are;
Atopic dermatitis is prevalent worldwide. It affects infants and children more, and the male to female ratio is 1:1.4. The illness decreases with increasing age.
Seborrheic dermatitis is prevalent throughout the world in all races. Males are affected more at the ages of puberty and then at 40.
Allergic contact dermatitis is prevalent worldwide with no age or race preference. It is more commonly found in females due to the increased use of nickel.
Irritant dermatitis is more commonly found in occupations involving repeated handwashing and certain chemicals. Such professions include healthcare, cooking and serving food, and hairdressers.
The following risk factors may make you susceptible to dermatitis;
Diagnosis is made based on history and examination.
A biopsy of the skin tissue can be taken to rule out other serious causes.
A patch test is done to find out the allergen in contact dermatitis.
All types of dermatitis can be confused for each other, and other conditions may mimic the presentation of dermatitis.
Atopic Dermatitis: The treatment of this specific type includes;
Seborrheic Dermatitis: The treatment of this type includes:
Contact Dermatitis: Treatment of contact dermatitis includes:
Dermatitis is a chronic condition. It relapses after treatment. This causes a significant financial burden. The episode of atopic dermatitis decreases as age increases. It is easier to cope with the problem by avoiding triggers and adopting lifestyle changes.
