Sicca syndrome - Sicca means "dryness", and may refer to Sjögren's syndrome, or to oral dryness (xerostomia) and eye dryness ("keratoconjunctivitis sicca") which is not caused by autoimmune diseasees such as Sjögren's.
The Missa Sicca (Latin: "dry Mass") was a common form of devotion used in the medieval Roman Catholic Church for funerals or marriages which were served in the afternoon, when a real Mass (liturgy) could not be said.
