Erythema is redness.

Epithelial cells are cells that form the epithelium. The epithelium (also known as covering tissue) surrounds the surfaces of certain organs (skin, digestive system, respiratory system, etc.). The epithelium of the skin is called the epidermis.

Erythrocytes, also known as red blood cells, are a key part of our blood system. Their main task is to transport oxygen from the lungs to all parts of the body and return carbon dioxide back to the lungs for exhalation. Erythrocytes are somewhat special cells because, unlike most other cells in the body, they do not contain a nucleus. They also have a special, biconcave shape, which allows them to adapt and travel through narrow capillaries. Their red color comes from hemoglobin, a protein that binds oxygen. A lack of erythrocytes or hemoglobin leads to anemia or blood deficiency.

Erythematous means reddened. Reddened skin can appear as part of various dermatological diseases (e.g., in atopic dermatitis, psoriasis, etc.).

Epicutaneous tests are tests used to detect potential contact allergies. These tests are usually performed on the skin of the back. Allergens are applied to the skin and then patches are placed over them. The allergens stay on the skin for 48 hours, then they are removed. This is followed by the first reading of the results, and usually the next day there is a second reading of the results. The test is positive if redness/swelling/blisters appear at the tested site.

It refers to inflammation in the respiratory area, where eosinophils (one of the subtypes of leukocytes) are present in large numbers, often elevated in atopy.

Eosinophils are a type of white blood cells or leukocytes that play a key role in our immune system. Their name derives from their ability to absorb the red dye eosin. Eosinophils are important in fighting against parasitic infections and also participate in inflammatory responses, which are often associated with allergies and asthma.

EMLA cream is a local anesthetic cream, used before various dermatological procedures (e.g., before removing mollusks) with the purpose of reducing pain. EMLA cream contains the active ingredients lidocaine and prilocaine.

Elocom is a local corticosteroid, used for the treatment of various inflammatory skin diseases (atopic dermatitis, psoriasis, eczematoid dermatitis, nummular dermatitis...).

Corticosteroids are medicines that act anti-inflammatory or reduce inflammation.
