Discoid lupus erythematosus is an autoimmune disorder affecting the skin. The disorder causes a skin rash or lesions that usually appear on the scalp, nose and cheeks. Loss of hair and changes in skin pigment also occur with this disorder. Permanent scarring can occur as lesions regress. Discoid lupus erythematosus is more common in women than men and appears to have a familial linkage. Having discoid lupus does not guarantee that you will develop systemic (body-wide) lupus erythematosus, a far more serious autoimmune disorder that can damage many different organs.
Rhinosinusitis is the inflammation of the nasal passages and sinus cavities. It is usually caused by allergies or an infection. It causes a combination of symptoms of rhinitis, (the medical term for nasal symptoms), and sinusitis, including: Runny nose. Post nasal drip.
The currently accepted definition of chronic rhinosinusitis (CRS) is inflammation of the nose and paranasal sinuses with objective evidence of disease by radiographs or nasal endoscopy and with a duration of symptoms and signs of at least 12 weeks.he gold standard for the diagnosis of an infectious agent in sinusitis is an antral tap of the maxillary sinus or the recovery of tissue from an infected sinus surgically. Recently endoscopically guided cultures have gained increased acceptance as a moderately good surrogate for invasive diagnostic procedures.
