Factitious and fraudulent fever.
The task of elucidating the etiology of fever of undertermined origin remains a major undertaking. Factitious fever is uncommonly considered of major importance in the differential diagnosis of fever of undetermined origin although it is a readily identifiable, syndrome and one that is easily excluded one it has been considered. Early identification may reduce the necessity for prlonged, expensive and potentially hazardous hospitalizations for such patients. A retrospective study identified 2.2 per cent (11 of 506) of all patients whose fever on their charts was coded as fever of undetermined origin as having factitious fever. These patients either created factitious fever by manipulation of the thermometer or fraudulent fever by self-induced means. A review of the literature yielded an additional 70 cases in which fever was either the sole factitious sign or part of a larger, more complex factitious illness. Patients were typically young, female and often associated with the medical profession. Patients with factitious fever differ from those with the stereotyped Munchausen's syndrome and may be difficult to recognize. Signs leading to the recognition of this syndrome are emphasized. Since the nature of the psychiatric illness may vary from patient to patient, early discovery may facilitate psychiatric intervention as such patients may be more amenable to therapy.
