Sinusitis is an inflammation of the membranes lining the paranasal sinuses (air-filled spaces around the nose) and the nose itself. It is also known as "rhinosinusitis." "Rhino-" means nose, and "sinus" means a space in the body.

Eczema is a common, chronic, non-infectious skin condition. The main symptom of this inflammatory disease is a very itchy rash. It often affects children. In many cases eczema gets better as the years go by, and it may go away for a while or disappear altogether.
