BACKGROUND Familial hemophagocytic lymphohistiocytosis is a fatal disease characterized by immune dysregulation from defective function of cytotoxic lymphocytes. Three causative genes have been identified for this autosomal recessive disorder (PRF1, UNC13D, and STX11). We investigated the molecular genetics of familial hemophagocytic lymphohistiocytosis in(More)
BACKGROUND This study was conducted to evaluate the performance of the COM.TEC cell separator (Fresenius HemoCare GmbH) for collecting CD34+ cells in pediatric patients who were intended to have autologous peripheral blood progenitor cell transplantation, with respect to collection variables, prediction power of CD34+ cell yield, and influence on donors.

Respiratory viruses (RVs) are a known cause of morbidity and mortality after hematopoietic stem cell transplantation (HSCT). In this retrospective study, we focused on the first 28 d after transplantation in pediatric HSCT recipients and showed that a multiplex PCR assay significantly increased RV detection compared with a viral culture method. Among 176(More)
An 8-year-old boy was diagnosed with precursor B-cell acute lymphoblastic leukemia. After intensified chemotherapy, he underwent sex-mismatched allogeneic cord blood transplantation. Postcord blood transplantation cytogenetic studies revealed engraftment failure evidenced by switching into the recipient type (XY), and, notably, various complex chromosomal(More)
Familial hemophagocytic lymphohistiocytosis (familial HLH or FHL) is a potentially fatal autosomal recessive disorder. Our previous study demonstrated that UNC13D mutations (FHL3) account for ∼90 % of FHL in Korea with recurrent splicing mutation c.754-1G>C (IVS9-1G>C). Notably, half of the FHL3 patients had a monoallelic mutation of UNC13D. Deep intronic(More)
BACKGROUND Diamond Blackfan anemia (DBA), characterized by impaired red cell production, is a rare condition that is usually symptomatic in early infancy. The purpose of this study was to assess nationwide experiences of DBA encountered over a period of 20 years. METHODS The medical records of 56 patients diagnosed with DBA were retrospectively reviewed(More)
There have only been a few reports and limited performance of peripheral blood stem cell (PBSC) collection in very small children weighing less than 10 kg. In this study, we intended to evaluate the safety and yield of PBSC collection, with the efficacy of PBSC transplantation (PBSCT) in the smallest children with solid tumors. From January 1998 to February(More)
OBJECTIVES The purpose of this study was to evaluate and compare the treatment outcomes of partial glossectomy with or without elective neck dissection in patients with tongue squamous cell carcinoma (SCCa). MATERIALS AND METHODS A total of 98 patients who were diagnosed with tongue SCCa and underwent partial glossectomy between 2005 and 2014 were(More)
Dear Editor, Deficiencies of coagulation factors such as fibrinogen and factors II, V, V + VIII, VII, X, XI, and XIII are called rare bleeding disorders (RBDs). Congenital factor V (FV) deficiency is caused by mutations in F5, which is located on chromosome 1q24, and accounts for about 8% of all RBDs. FV is important for modulating thrombin production.(More)
