Primary polydipsia Alcoholism may cause physiological thirst since ethanol inhibits vasopressin, the hormone primarily responsible for water retention in osmoregulation. The following conditions should also be excluded: DI, cerebral salt wasting, pseudohyponatraemia caused by hyperlipidemia or hyperparaproteinemia, SIADH, mineralcorticoid deficiency, salt-wasting nephropathy, nephrotic syndrome, chronic heart failure and cirrhosis. Tobacco smoking is an often overlooked factor linked to hyponatremia, due to the ADH-releasing effect of nicotine, although this is usually limited to heavy smokers. One study suggested that around 70% of patients with self-induced polydipsia were tobacco smokers. Diagnostic tests for primary polydipsia usually involves the fluid deprivation test to exclude ADH
In silico medicine cultural (HSBC) characteristics of patient behavior becomes more sophisticated, there is speculation that virtual patients may replace patient actors in medical school curriculum. Additionally, there are projects underway that utilize virtual cadavers, computer simulated models of human anatomy based on CT images of real people. In silico medicine "In silico" medicine (also known as "computational medicine") is the application of "in silico" research to problems involving health and medicine. It is the direct use of computer simulation in the diagnosis, treatment, or prevention of a disease. More specifically, "in silico" medicine is characterized by modeling, simulation, and visualization of biological
