Oct 3, 2016 · The concept of pyrexia as a protective physiological response to aid in host defence has been challenged with the awareness of the severe metabolic stress induced by pyrexia. The host response to pyrexia varies, however, according to the disease profile and severity and, as such, the management of pyrexia should differ; for example, temperature control is safe and effective in septic shock but ...

Many clinical researchers have attempted to more precisely define FUO ...
Sep 16, 2016 · Pyrexia of unknown origin (PUO) is a syndrome that has long tested the skills of physicians to achieve a diagnosis in affected patients. By definition, patients included in this syndrome will be more difficult to diagnose as they have already resisted classification during baseline investigations.
Introduction. The definition of pyrexia of unknown origin (PUO) dates back to 1961; it was described as a persistent fever above 38.3°C (100°F) that evades diagnosis for at least 3 weeks, including 1 week of investigation in hospital. 1 This definition has evolved with faster and more accurate diagnostic techniques and changing models of care, and a week of hospitalisation is no longer ...
