Question: What legend that lends its name to a modern medical term, inspired the plot of the horror film Ghostkeeper?

Passages:
Causa Mortis is a satiric play by Jacob M. Appel that lampoons the modern medical establishment.  The plot focuses on a woman, Eleanor, whose brain surgeon has accidentally left his watch in her skull.  Her daughters urge her to have the timepiece extracted before it harms her, but every surgeon who attempts to remove it dies during the process.  Critic Donald Calamia described the play as "a needle in the eyes of an industry that far-too often refuses to admit its human failings." Syncopy Films Inc. is a British film production company based in London, England.  The company was founded by film director, screenwriter and producer Christopher Nolan and his wife Emma Thomas.  The name Syncopy Films derives from "syncope", the medical term for fainting or loss of consciousness. Side Effects is a 2005 romantic comedy about the pharmaceutical industry, directed by Kathleen Slattery-Moschkau and starring Katherine Heigl as Karly Hert, a pharmaceutical "detailer", who becomes disillusioned with the lack of ethics in the pharmaceutical industry and has tough choices to make.  The film also stars Lucian McAfee, Dorian DeMichele, Dave Durbin, Temeceka Harris.  The film's title is a reference to the medical term "side effects". Ghostkeeper is a 1981 Canadian independent horror film directed by Jim Makichuk.  The story centers on a trio of snowmobilers in the Canadian Rockies who become stranded at an abandoned hotel, where an old woman is hiding an evil entity within the basement.  The film's plot is inspired by the Windigo legend of North America. In medicine, asthenization is a condition experienced by astronauts following long-term space flight, in which following return to Earth the astronaut experiences symptoms such as fatigue, irritability, lack of appetite, and sleep disorders.  The condition's name derives from asthenia, which is a medical term denoting a feeling of weakness without actual loss of strength. In modern medical English, the term typhus refers to a group of rickettsioses only.  Some other groups of infectious diseases also have similar names: Eileen Georgina "Georgie" Collins (née Given; June 12, 1925 – May 3, 2017) was a Canadian film, stage, and television actress.  Collins is known for her role in the 1981 cult horror film "Ghostkeeper", as well as her part in "Lonesome Dove: The Series" (1995). A microtiter plate (spelled Microtiter is a registered trade name in the United States) or microplate or microwell plate or multiwell, is a flat plate with multiple "wells" used as small test tubes.  The microplate has become a standard tool in analytical research and clinical diagnostic testing laboratories.  A very common usage is in the enzyme-linked immunosorbent assay (ELISA), the basis of most modern medical diagnostic testing in humans and animals. Biocompatibility is related to the behavior of biomaterials in various contexts.  The term refers to the ability of a material to perform with an appropriate host response in a specific situation.  The ambiguity of the term reflects the ongoing development of insights into how biomaterials interact with the human body and eventually how those interactions determine the clinical success of a medical device (such as pacemaker, hip replacement or stent).  Modern medical devices and prostheses are often made of more than one material so it might not always be sufficient to talk about the biocompatibility of a specific material. The legend lends its name to the controversial modern medical term Wendigo psychosis, described by psychiatrists as a culture-bound syndrome with symptoms such as an intense craving for human flesh and a fear of becoming a cannibal.  In some Indigenous communities, environmental destruction and insatiable greed are also seen as a manifestation of Wendigo Psychosis.
