Eczema (Atopic Dermatitis)

Eczema, or atopic dermatitis, is the most common rash presenting during infancy and childhood. Generally red, dry, scaly, and extremely itchy, it often presents with a characteristic distribution on the body. In infants, it usually presents in the first few months of life, and it typically involves the cheeks, the back of the ears, the buttocks, the bends of the arms, and behind the knees. As children grow older, the rash can spread to involve any place on the body that can be rubbed or scratched, but the classic distribution continues to be in the folds of the arms and behind the knees.

Hives, or Urticaria, appears on the body as raised welts with red coloration either directly on the hive or on its periphery. These lesions can be quite small, about the size of a mosquito bite, or very large, measuring several inches in diameter. Hives will typically come and go, moving from one place on the body to another within minutes or hours. One thing for sure: they are generally intensely itchy!

Latex Allergy

Allergy to latex was first described in the late 1970s. Since then, it has been recognized to be a major health concern, especially among health care workers and other high risk groups. It has been estimated that as much as 6% of the adult population may be sensitized to latex and at risk of allergic symptoms upon exposure.  Reactions to the latex allergen can be caused by direct contact or by inhalation of latex particles. Direct contact with proteins in the latex causes sensitization and subsequent allergic reactions.
