BACKGROUND
AND PURPOSE: Patients with acute leukemia experience prolonged periods of neutropenia due to their disease or its treatment. For this reason, they often develop serious infectious complications. Although antibiotic therapy has improved in recent years, the fatality rate from infection remains high. For the control of infection, protected environment was developed. But because of economic issue, most of chemotherapy with acute myeloid leukemia have conducted in non-protected environment. So this study compared the rate of complete remission, days with neutropenia, rate of fever, rate of positive culture, rate of overt infection and use of antibacterial and antifungal agents with patients within non-protected environment and protected environment, retrospectively. Patients with acute myeloid leukemia during first remission induction chemotherapy were eligible for this study. METHODS: Retrospective analysis was conducted between patients in non-protected (25 patients) and protected environment (14 patients) with acute myeloid leukemia during remission induction chemotherapy. RESULTS: Rate of overt infection, rate of fever, rate of positive culture and rate of use of antibiotics were significantly high in patients within non-protected environment compared with patients within protected environment. There were no differences in rate of complete remission and days of neutropenia. CONCLUSIONS: This study suggests protected environment for patients with acute myeloid leukemia during remission induction chemotherapy could reduce rate of overt infection, and rate of use of antibiotics.

AbstractAbstract PDF
Adult-onset Still's disease (AOSD) is an inflammatory disorder that's characterized by daily, spiking high fever, arthritis and an evanescent, salmon-pink rash. AOSD is diagnosed purely on the basis of the typical clinical features of the illness. The symptoms commonly include swelling of the lymph nodes, enlargement of the spleen and liver, and a sore throat. AOSD is difficult to differentiate from systemic lupus erythematosus (SLE) due to the similar clinical manifestations. We report here on a case of a 16-year-old female patient with autism and epilepsy and who complained of daily spiking fever for 20 days. The patient had maculopapular skin rashes on the face and whole body and lymphadenopathy. The liver function tests were elevated mildly. The initial rheumatoid factor (RF) and antinuclear antibody (ANA) tests were negative. We diagnosed her as having adult-onset Still's disease according to the criteria of Yamaguchi. We successfully treated her with oral prednisolone. But her antinuclear antibody test was changed to positive after discharge. So we finally diagnosed her as having SLE.

AbstractAbstract PDF
Evaluation of a fever of unknown origin (FUO) is complex. Recently, PET scanning has been approved for screening in FUO evaluation. We treated three cases of FUO associated with increased FDG uptake in the bone marrow of the femur and tibia on the fusion PET/CT; all three had the same pattern of uptake. Bone marrow biopsies revealed mature lymphocyte and histiocyte infiltration and myxoid changes in one case, and cortical bone involvement in another case. The cases were all young females who had fever with neutropenia and relative lymphocytosis that lasted for several weeks and then remitted spontaneously. Even though the results of the studies were not diagnostic, the unique uptake pattern on PET/CT and the histology might be related to the cause of the illness and should be studied further to assess the association with classic FUO.
