Rheumatism {rum'-at-izm) [pevfiaTiofiog']. Rheumatic 

 Fever; a disease characterized by severe, fitful, and 

 shifting lancinating pains in the joints, and in the 

 muscles, with fever, and inflammatory swelling of the 

 affected parts. It may be acute or chronic. Acute 

 rheumatism is a self-limited affection lasting, untreated, 

 for about six weeks. It is characterized by elevation 

 of temperature, acid perspiration, and pain, redness 

 and swelling of various large joints, often with effu- 

 sion. Inflammation of the serous membranes, particu- 

 larly of the endocardium, is a common association. 

 There is a great tendency to relapses. The blood 

 contains an excess of fibrin, and is said to contain 

 an excess of lactic acid. To this latter cause, also to 

 cold and to microorganisms, has been ascribed the ori- 

 gin of the affection. Subcutaneous nodules form 

 frequently in connection with the fibrous structures, 

 such as tendons, fasciae, etc. The disease is most 

 frequent in young persons under twenty-five years 

 of age and in those who show a strong hereditary
