visceral leishmaniasis is the second most common cause of fever of unknown origin in our study. this disease is not common in adults, although it's endemic among the pediatric age group. the majority of the affected individuals were young. high grade spiking fever, chills and splenomegaly were unique findings. other common findings were neutropenia, anemia, abnormal liver function tests, s...

UNLABELLED Fever of unknown origin (FUO) is a challenging diagnostic problem. Timely identification and precise localization of the causing process are critical for appropriate patient management. The present prospective study evaluates the role of PET/CT using (18)F-FDG in the investigation of FUO. METHODS A total of 48 consecutive patients (25 men, 23 women; age range, 24-82 y) with FUO und...

Fever of unknown origin (FUO) is generally defined as a fever greater than 38.3°C on several occasions during a period longer than 3 weeks for which the etiology behind cannot be diagnosed at the end of at least 1 week hospital stay. Conventional diagnostic methods are still not adequate to reveal underlying reason in approximately 50% of patients with FUO. In patients with certain diagnosis, t...

Infections remain the most frequent cause of fever of unknown origin (FUO) in developing countries. Some cases of fever remain a mystery and patients are discharged without knowing the cause. Prehospital healthcare facilities vary between countries, and even within the same country. FUO was first described in 1961 by Petersdorf and Beeson when they established the three criteria that define FUO...

Background. The presence of ulcerative colitis (UC) with no bowel symptoms, as fever of unknown origin (FUO), is uncommon. Objective. To describe the case of an 80-year-old woman who presented with fever, with a history of UC under treatment with mesalazine. Case Presentation. She was admitted due to fever lasting for 12 days with no associated symptoms. Seven years earlier, she was diagnosed w...

Purpose: Patients with fever of unknown origin (FUO) [1] are usually examined with many different modalities, such as conventional radiography of the lungs, CT of the abdomen and scintigraphy, however, in more than 50% without detection of the fever generating focus. Leucocyte scintigraphy is considered as the diagnostic standard [2], however, it is unspecific. F-FDG-PET [3] has been evaluated ...

In immunocompromized hosts, febrile episodes have an unknown origin (FUO) in about fifty per cent of cases. In this preliminary study we evaluated the role of abdominal and pleural ultrasound (US) examination for early detection of infectious sites. US exploration was performed in a cohort of 14 consecutive FUO patients early after fever onset, at patients' bedside, by a hematologist trained in...

In this survey involving 10 hospitals, we analyzed data on 80 Japanese patients from the Shin'etsu area (Nagano-ken and Niigata-ken) who were observed for fever of unknown origin (FUO). Our objectives were to identify the underlying causes and the relevant diagnostic methods. Fourteen of the patients died of the underlying illness. The cause of the FUO was infection in 43 patients, allergic or ...
