To assist the ultrasound (US) differential diagnosis of solid breast tumors by using stepwise logistic regression (SLR) analysis of tumor contour features, we retrospectively reviewed 111 medical records of digitized US images of breast pathologies. They were pathologically proved benign breast tumors from 40 patients (i.e., 40 fibroadenomas) and malignant(More)
BACKGROUND To describe the prevalence and sonographic findings and ultrasound diagnostic accuracy of the right side colonic diverticulitis in patients having right lower abdominal pain with indeterminate nature. METHODS A total of 934 patients with acute right lower abdominal pain of clinically indeterminate nature were referred for ultrasound examination(More)
Five osteosarcoma (OS) cell lines, 37 OS tumors and 9 corresponding non-neoplastic samples were genotyped by Affymetrix 10 K 2.0 SNP array. Regions of high level amplification and homozygous deletion were identified and validated by quantitative PCR and FISH. Certain recurrent cytogenetic alterations were more frequent in recurrent/metastatic than in(More)
BACKGROUND AND PURPOSE Subcutaneously implanted central venous access devices (SICVADs) are a common route of intravascular access for pediatric patients with cancer. This study was performed to evaluate the risk for SICVAD-related infection in a large consecutive series of unselected children with cancer in a single medical center. METHODS The medical(More)
Acute promyelocytic leukemia (APL) is a distinct subtype of acute myeloid leukemia (AML) and is rare in children (< 10% of childhood AML). It tends to bleed with disseminated intravascular coagulation (DIC) and intracranial hemorrhage complication is often fatal. We report a 12-year-old child with APL who suffered a subdural hemorrhage and initially(More)
In this study, we reported the outcomes of hematopoietic stem cell transplantation (HSCT) as a treatment modality for pediatric patients admitted over the past 20 years in a single institute. From January 1989 to January 2007, 26 patients with a median age of 8 years underwent 14 matched sibling donor (MSD) and 12 alternative donor (AD) transplantations.(More)
To identify the prognostic factors and evaluate the impact of chemotherapy regimens on the outcomes of pediatric osteosarcoma of the extremities. Patients younger than 18 years and diagnosed with high-grade osteosarcoma of the extremities during the period between January 2004 and December 2011 were included for retrospective analysis. Demographic(More)
To determine whether T cell engraftment and recovery of B cell immunity could be improved, we prospectively treated 15 children with severe combined immunodeficiency disease (SCID) with megadoses of haplocompatible CD34(+) cells and a fixed number of CD3(+) cells without previous myeloablative chemotherapy. Evidence of T cell engraftment was seen in 73% of(More)
BACKGROUND Some studies have proved that intravenous busulfan with cyclophosphamide (used as a component of conditioning regimens for hematopoietic stem cell transplantation) is safer and has fewer complication than oral busulfan in adults, whereas the same proof in pediatric patients is only limited, with no reported data so far from Asian countries.
