A young male was referred to us for evaluation of fever of unknown origin (FUO). He had history of recurrent painful oral ulcers for one year and moderate to high grade fever, pustulopapular rash, and recurrent genital ulcers for 6 months and hemoptysis for 3 days.

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...

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...

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)...
