Eczema

What is it and what causes it?

Eczema (atopic dermatitis) is a non-infectious, inflammatory skin condition characterised by dry, red, swollen and itchy skin. In severe cases lesions may bleed, weep, crust or become infected. While the specific cause of eczema is unknown, many factors are understood to be linked to the condition. These may include other diseases, environmental irritants (chemicals, changes in temperature, tobacco smoke) allergies, stress or a genetic predisposition.

Although presentation is more commonly seen in early childhood (particularly infants), eczema can affect people of all ages.

TSC Treatment

There are many treatment options for the management of eczema, and as every individual case differs it is recommended to consult a qualified professional to determine the best course of treatment for you.

  • Moisturisers/emollients to hydrate the skin.
  • Anti-inflammatory ointments or topical steroids to reduce the discomfort and inflammation.
  • Ultraviolet Radiation Therapy (UVB): Exposing the skin to Type B UV light suppresses the skin’s inflammatory response, reduces symptoms of swelling and itchiness, increases Vitamin D production and may aid the skin’s natural antibacterial properties.
  • Oral medication/oral corticosteroids may be prescribed for more severe cases or instances in which other methods have shown limited success.

Effective treatments for eczema typically consist of a combination of topical steroid application and ultraviolet light therapy (UVB).
