Had markedly anarchic dietary behaviour with alternating anorexia and bulimia, or even self-induced vomiting. These disturbances in dietary behaviour fall within the context of an unusual neurotic syndrome, predominantly hysterical. There were also menstrual problems, most often amenorrhoea. The physiopathological relations between these symptoms and signs may be envisaged as follows: the initial psychological problems explain the dysorexia; the menstrual difficulties are related at one and the same time to the psychological problems and the dysorexia; the latter is responsible for the parotidomegaly and for disturbances in carbohydrate and lipid metabolism.
