Purpose of the study Fever of unknown origin (FUO) is a challenging clinical entity in HIV patients. FDG-PET/CT is well validated in the work-up of FUO in HIV-negative patients but in HIV viremic patients, metabolism of HIV reactive lymph nodes could decrease its specificity. We prospectively evaluated the usefulness of FDG-PET/CT in FUO in HIV-positive patients and in particular whether HIV vi...

Background Fever of unknown origin (FUO) is a challenging problem worldwide. FUO, as defined by Petersdorf and Beeson in 1961 [1] , includes illness persisting for 3 weeks or more, occasional episodes of a fever 38.3°C or more, and an unclear cause upon examination after one week of hospitalization. Recently, only one retrospective study of FUO have been conducted in the south China, but there ...

Fever of unknown origin (FUO) is a challenging condition in the practice of internal medicine. It frequently requires use of complicated tests and applications in the diagnostic workup. We here report a patient presented with FUO who was diagnosed with osteomyelitis by biopsy after a positive Fludeoxyglicose Positron Emission tomography (FDG-PET) scan.

The original criteria for fever of unknown origin (FUO) as set forth in 1961 by Petersdorf and Beeson were fever higher than 38.3°C on several occasions of at least 3 weeks’ duration and uncertain diagnosis after 1 week of study in the hospital (1). This definition was later revised, and the criterion of 1 week of hospitalization has been replaced by 3 days of hospitalization or three outpatien...

BACKGROUND The etiology of fever of unknown origin (FUO) may differ from different countries. This study was conducted to evaluate the etiology of FUO in patients attending SKIMS, a tertiary care teaching hospital, at Srinagar, Kashmir, India. METHODS From July 2010 to September 2012, this study was done to examine the profile of patients with FUO. The classic FUO was defined as three outpati...

Fever is a common complaint in children. In most cases, fevers are due to selflimited viral infections and require no more than symptomatic treatment. Sometimes fever is due to common bacterial infections that are diagnosed by history and physical examination and require antibiotic treatment without laboratory evaluation. In a few clinical situations, the cause of fever is not easily identified...

I n elderly patients, the syndrome of fever of unknown origin (FUO) differs in several important regards from that seen in younger patients. The causes of FUO in the elderly are rarely benign or selflimited; almost always, an elderly patient with FUO will be found to have a serious illness as the cause of the fever.':" Factitious and fraudulent causes of FUO are exceedingly rare in the elderly....

BACKGROUND Causes of FUO change according to medical innovations, modifications of social circumstances, and emerging health risks. Aim. To describe the epidemiology of classical FUO, the time and procedures to achieve a definitive diagnosis, and to underline the variables useful in distinguishing FUO categories. Setting. A third-referral center in Mexico City. METHODS Patients admitted with ...
