Functio laesa is a term used in medicine to refer to a loss of function[1][2] or a disturbance of function.[3] It was identified as the fifth sign of acute inflammation by Galen,[4] who added it to the four signs identified by Celsus (tumor, rubor, calor, and dolor). The attribution to Galen is disputed,[3] and has variously been attributed to Thomas Sydenham[5] and Rudolf Virchow.[6] [edit] References | Inflammation | | | Acute | | | | Chronic | | | | Processes | | | | Specific types | | | CNS ( Encephalitis, Myelitis) · Meningitis ( Arachnoiditis) · PNS ( Neuritis) · eye ( Dacryoadenitis, Scleritis, Keratitis, Choroiditis, Retinitis, Chorioretinitis, Blepharitis, Conjunctivitis, Iritis, Uveitis) · ear ( Otitis, Labyrinthitis, Mastoiditis) | | | | | | | | | | | | mouth ( Stomatitis, Gingivitis, Gingivostomatitis, Glossitis, Tonsillitis, Sialadenitis/ Parotitis, Cheilitis, Pulpitis, Gnathitis) · tract ( Esophagitis, Gastritis, Gastroenteritis, Enteritis, Colitis, Enterocolitis, Duodenitis, Ileitis, Caecitis, Appendicitis, Proctitis) · accessory ( Hepatitis, Cholangitis, Cholecystitis, Pancreatitis) · Peritonitis | | | | | | | | | | | | | | | | | | | | | | | | | | | |
