We describe a 23-year-old retired military officer who was immunocompetent but diagnosed with hemophagocytic syndrome (HPS) by Plasmodium vivax infection. Initially, the patient was suspected to have toxic hepatitis related to heavy drinking. But abnormal hematologic findings required a further bone marrow examination and the diagnosis of HPS was made.(More)
We report two childhood cases of acute leukemia with t(16;21)(p11.2;q22) and FUS-ERG rearrangements. Patient 1 (14 years old) was initially diagnosed with acute myeloid leukemia. Chromosome study showed a t(16;21)(p11.2;q22) clone in more than one third of the cells analyzed, and further investigation with reverse-transcriptase polymerase chain reaction,(More)
Gardner syndrome (GS) is an abnormality of familial adenomatous polyposis accompanied by characteristic jaw lesions. Gardner syndrome intestinal polyps have a 100% risk of undergoing malignant transformation; consequently, early identification and surgical intervention of the disease are important to prolong the life of the patient. We present a case of GS(More)
BACKGROUND The aims of this study were to compare several DNA extraction methods and 16S rDNA primers and to evaluate the clinical utility of broad-range PCR in continuous ambulatory peritoneal dialysis (CAPD) culture fluids. METHODS Six type strains were used as model organisms in dilutions from 10(8) to 10(0) colony-forming units (CFU)/mL for the(More)
BACKGROUND The aim of this study is to investigate useful perioperative monitoring markers by comparing serial levels of serum procalcitonin (PCT), interleukin 6 (IL-6), and C-reactive protein (CRP) in routine surgical circumstances. METHODS In 285 surgeries of 277 patients, blood samples were obtained serially, at least three times per patient: within 48(More)
Thrombotic thrombocytopenic purpura (TTP) is a devastating systemic disorder that is characterized by microangiopathic hemolytic anemia, thrombocytopenia, neurological dysfunction, and renal failure. In the hereditary form of TTP, severe deficiency of ADAMTS13, a plasma metalloprotease that cleaves von Willebrand factor, is associated with the development(More)
A 55-year-old Korean woman was initially diagnosed with acute myelomonocytic leukemia (AML). After induction chemotherapy was performed using cytarabine, idarubicin, and G-CSF, complete remission (CR) was subsequently achieved following reinduction chemotherapy using the same chemotherapeutic agents. Thirty-six months after the initial CR, an increase in(More)
INTRODUCTION Coagulase-negative staphylococcus (CoNS) is the most common pathogen in continuous ambulatory peritoneal dialysis (CAPD)-associated peritonitis. There is no well-organized, standardized database for CoNS, and few studies have used gene sequencing in reporting species distribution in CAPD peritonitis. In the present study, we used 3 housekeeping(More)
BACKGROUND We investigated the prevalence of plasmid-mediated quinolone resistance and its association with extended-spectrum beta-lactamase (ESBL) and AmpC beta-lactamase in Enterobacteriaceae. METHODS A total of 347 non-duplicated isolates of Enterobacteriaceae were collected between August and October 2006 from 2 hospitals. Qnr determinant screening(More)
Because plasma cell leukemia (PCL) is a rare and distinct variant among plasma cell dyscrasias, recent clinical and cytogenetic studies have been performed in different ethnic groups to define the characteristics of these PCL patients. As far as we know, IGH rearrangements involving t(11;14) and (14;16) are significantly more frequent in PCL than in myeloma(More)
