I have no idea what PDSI is, i can only assume is some sort of ASI...like you said, it take a lot of time and training to learn the entire system, so it should have an ASI. I worked with the system for a year on a daily basis since i was 92A working in the SSA, and i don't think i learn not even a quarter of the system.
The term anorexia nervosa was established in 1873 by Queen Victoria âs personal physician, Sir William Gull. The term anorexia is of Greek origin: an - (á¼Î½-, prefix denoting negation) and orexis (á½ÏÎµÎ¾Î¹Ï, appetite), thus translating to nervous absence of appetite.he history of anorexia nervosa begins with descriptions of religious fasting dating from the Hellenistic era and continuing into the medieval period.
A number of investigators have been interested in the concept that anorexia nervosa occurs as a continuum of chronic dieting behavior. Weight loss-related amenorrhea and exercise-induced amenorrhea have similar endocrine profiles, suggesting that all three entities have similar hypothalamic mechanisms.
