A man arrives to deliver leeches at a service for burned patients at the CHU hospital Pellegrin in Bordeaux, Southwestern France, November 23, 2016. The leech, Hirudo medicinalis, is an invertebrate 3 cm long in adulthood which after being considered indispensable in the 19th century to cure many affections such as osteoarthritis, phlebitis, tension, then fell in desuetude while it harboured qualities that made it indispensable today in plastic surgery.
