OBJECTIVE Fever of unknown origin (FUO) can be caused by many diseases, and varies depending on region and time period. Research on FUO in Japan has been limited to single medical institution or region, and no nationwide study has been conducted. We identified diseases that should be considered and useful diagnostic testing in patients with FUO. DESIGN A nationwide retrospective study. SETT...

BACKGROUND/AIM Fewer of unknown origin (FUO) remains amongst the most difficult diagnostic dilemmas in contemporary medicine. The aim of this study was to determine the causes of FU and to identify the methods of diagnosis in patients with FUO in a tertiary care setting in the Republic of Macedonia.

Prolonged fever is a common problem faced by clinicians in everyday practise. Since the first description of the entity “fever of unexplained origin” by Petersdorf and Beeson in 1961, the case definition of this entity was further refined with modifications over the last 55 years. Durack and Street proposed noteworthy changes in the definition of “fever of unknown origin (FUO)”. First, they div...

UNLABELLED F-18 FDG PET-CT scanning plays an important role in the management of fever of unknown origin (FUO). Some elderly patients with FUO can be in their terminal stage of life. An elderly woman was referred for a PET-CT scan to find the etiology of FUO. The scan was inconclusive but showed significantly reduced FDG uptake in the brain and heart, despite normal physiological uptake in the ...

BACKGROUND Fever of unknown origin (FUO) is among the most conditions which poses challenge in diagnosis. The presence of information on regional patterns of FUO will shorten the time for diagnosis and reduces health services costs. There are almost no previous studies describing the etiology of FUO in children of Egypt or nearby countries. AIM OF THE STUDY To determine different causes of FU...

background fever of unknown origin (fuo) is defined as the presence of fever in a child for eight or more days that a careful history and physical examination and preliminary laboratory results failed to reveal the probable cause of the fever. the causes of fuo are different according to geographical regions and age. objectives the current study aimed to evaluate the common causes of childhood ...

This review focuses on the diagnostic value of hybrid F18-FDG Positron Emission Tomography/Computerized tomography (PET/CT) in fever of unknown origin (FUO) and inflammation of unknown origin (IUO). Due to the wide range of possible causes both FUO and IUO remain a clinical challenge for both patients and physicians. In addition, the aetiology of IUO shows the same variation in diseases as the ...

The aim of this study was to determine the causes of fever of unknown origin (FUO) at a tertiary care teaching hospital in Pakistan.

We reviewed the medical records of all patients aged > 12 years with a primary diagnosis of FUO. We excluded those who di...

OBJECTIVES To evaluate the clinical characteristics and imaging results (CDS, 18-FDG-PET) of patients with large vessel giant cell arteritis (LV-GCA) presenting as fever of unknown origin (FUO). METHODS From a series of 82 patients with GCA we identified 8 patients with FUO as initial disease manifestation. Clinical characteristics and results of CDS and 18-FDG-PET were analysed. Patients wit...
