Emile Achard
From Wikipedia, the free encyclopedia
Emile Achard, full name Emile Charles Achard (July 24, 1860 - 1944) was a French internist. For much of his career he was a professor at the University of Paris. He also was also a physician at Hôpital Cochin in Paris.
Achard's name is associated with several facets in medicine. In 1896 with Dr. Raoul Bensaude (1866-1938) he identified a disease he called paratyphoid fever, and was able to isolate the cause to a microbe named salmonella paratyphi. Also a postmenopausal condition known as the "diabetic-bearded woman syndrome" is now known as the Achard-Thiers syndrome. Also the eponymous Achard's syndrome is arachnodactyly associated with joint laxity in the extremities.
In 1897 Achard and Joseph Castaigne (1871-1951) developed a urinary test using methylene blue dye to examine kidney function. The criteria used was to find the percentage of dye, injected subcutaneously, that showed up in the urine within a 24-hour period. This procedure was to become known as the Achard-Castaigne test. With Castaigne he published Manuel des maladies du tube digestif.
