We conducted a prospective study to update our knowledge of fever of unknown origin (FUO) and to explore the utility of a structured diagnostic protocol. From December 2003 to July 2005, 73 patients with FUO were recruited from 1 university hospital (n = 40) and 5 community hospitals (n = 33) in the same region in The Netherlands. FUO was defined as a febrile illness of >3 weeks' duration, a te...

Fevers of unknown origin (FUO) in HIV/AIDS patients are due to the same infectious causes that are common in this subset of compromised hosts but manifest clinically as prolonged fevers. In North America, the most common etiologies of FUO in HIV/AIDS are due to intracellular pathogens, i.e., disseminated Mycobacterium avium-intracellulare, Pneumocystis carinii pneumonia (PCP), fungi or cytomega...

Twenty patients affected by fever of unknown origin (FUO), due to a likely infection of the muscular or skeletal tissues, were studied by a Total Body scan with a monoclonal antibody fragment (Leukoscan) labelled with Tc-99m. The diagnostic procedure helped reach a final diagnosis in 8 out of the 20 patients because it identified the focus of the infection of the muscles or bones in joint proxi...

Background: The term ‘fever of unknown origin’ (FUO) was first introduced by Petersdorf and Beeson in 1961, it is defined as recurrent fever >38.3°C, lasting for >3 weeks, remaining undiagnosed after 1 week in-hospital evaluation. etiologies classic FUO include mainly infections, malignancies, non-infectious inflammatory diseases, miscellaneous causes, while some cases remain undiagnosed....

introduction systemic lupus erythematous (sle) is among rheumatic diseases of unknown etiology. fever of unknown origin (fuo) has been rarely reported to be the presenting sign of sle. presence of four or more sle criteria is diagnostic for the disease. however, presentations may occur serially which make it much more difficult to diagnose an already questioned fuo. case presentation our case o...

Methods We included patients from a prospective diagnostic test trial called: levels of total and glycosilated ferritin in children with systemic onset juvenile idiopathic arthritis (SoJIA) and children with other causes of FUO. Patients had been referred with the diagnosis of FUO, defined as: temperature of >38.3°C at least twice per week during two or more weeks and without a clear diagnosis ...

INTRODUCTION Human parechovirus (HPeV) is one of the recently described picornaviridae viruses that have been associated with fever of unknown origin (FUO), clinical sepsis, gastroenteritis, meningitis, or encephalitis in very young infants. The aim of this study is to describe the epidemiology and clinical features of these viruses. PATIENTS AND METHODS A prospective multicentre 3-year study...

BACKGROUND Breast-feeding has shown to give a reduction in the risk of hospitalization due to respiratory tract infections and gastrointestinal conditions during the first two years of life. The association of breast-feeding with all admission causes and with fever of unknown origin (FUO) was analysed. METHODS A case-reference study in Cantabria (northern Spain) was carried out. Cases (n=336)...
