Featured Article: Guinea worm disease (Dracunculiasis)

A method used to extract a guinea worm from the leg of a human.
Guinea worm disease (GWD), also called dracunculiasis, is a parasitic infection caused by the nematode (roundworm) Dracunculus medinensis (guinea worm). The disease is spread by drinking water contaminated by copepods that harbor the guinea worm larvae. The larvae mate in the human body and the females mature and develop into two-to-three-foot-long worms, which often forms a painful lesion on a lower limb and may exit excruciatingly through a leg or foot. GWD is the only human disease known to be contracted exclusively by drinking water.

The guinea worm is one of the best historically documented human parasites, even noted in the ancient Ebers Papyrus. Once widely spread through tropical Africa and Asia, the incidence of the disease has gone from an estimate of more than 3 million cases a year in 1986 to only 542 reported cases in 2012. It may become the second human disease to be eradicated, after smallpox, and the first parasitic disease eradicated. And this has been accomplished not with vaccines or medical treatment, but largely through education and behavior change, along with treatment of contaminated water with larvicides and provision of clean water.

Marie Antoinette
Marie Antoinette (November 2, 1755 – October 16, 1793), the Archduchess Maria Antonia of Austria, was later titled, Marie Antoinette, Queen of France and Navarre, as the queen consort and wife of Louis XVI of France. She was the daughter of the Holy Roman Emperor Francis I and Maria Theresa of Austria. She was married to Louis XVI at age 14 in a move to seal a favorable alliance between France and Austria. She was the mother of "the lost Dauphin" (Louis XVII), named so because of rumors regarding his uncertain demise during the infamous Reign of Terror during the French Revolution.

Marie Antoinette is remembered for her legendary excesses, and for her death: she was executed by guillotine in 1793 for the crime of treason. In recent years some modern historians have attempted to exculpate her image; many of her excesses were common practices among other European royalty of that era; additionally, she displayed tremendous loyalty and courage during the dark and tempestuous days of the French Revolution.
