Hematopoietic Cell Transplantation with Reduced Intensity Conditioning Using Fludarabine/Busulfan or Fludarabine/Melphalan for Primary Immunodeficiency Diseases.

Purpose: The purpose of our study was to compare the safety and efficacy of hematopoietic cell transplantation (HCT) using fludarabine (Flu)-based reduced intensity conditioning (RIC) with busulfan (BU) or melphalan (Mel) for primary immunodeficiency diseases (PID).

Methods: We retrospectively analyzed transplant outcome, including engraftment, chimerism, immune reconstitution, and complications in 15 patients with severe combined immunodeficiency (SCID) and 27 patients with non-SCID PID. The patients underwent Flu-based RIC-HCT with BU (FluBU: 7 SCID, 16 non-SCID) or Mel (FluMel: 8 SCID, 11 non-SCID).

Early detection of the PAX3-FOXO1 fusion gene in circulating tumor-derived DNA in a case of alveolar rhabdomyosarcoma.

Cell-free DNA (cfDNA), which are small DNA fragments in blood derived from dead cells including tumor cells, could serve as useful biomarkers and provide valuable genetic information about the tumors. cfDNA is now used for the genetic analysis of several types of cancers, as a surrogate for tumor biopsy, designated as "liquid biopsy." Rhabdomyosarcoma (RMS), the most frequent soft tissue tumor in childhood, can arise in any part of the body, and radiological imaging is the only available method for estimating the tumor burden, because no useful specific biological markers are present in the blood.

Therapeutic Effect of Linezolid in Children With Health Care-Associated Meningitis or Ventriculitis.

We evaluated the efficacy of linezolid treatment in 6 children with health care-associated meningitis or ventriculitis (HCAMV) caused by gram-positive cocci. All children were diagnosed and treated at the Ehime University Hospital between January 2010 and December 2017. Of these, 5 were treated with linezolid as an empirical therapy.

Hematopoietic cell transplantation for myeloid/NK cell precursor acute leukemia in second remission.

Myeloid/natural killer cell precursor acute leukemia (MNKPL) is a rare leukemia subtype characterized by a high incidence of extramedullary infiltration. No appropriate treatment strategy has so far been developed. Acute myelogenous leukemia-type chemotherapy combined with L-Asparaginase is an effective treatment for MNKPL.

Ocular manifestation in myeloid/NK cell precursor acute leukemia: a case report. Diagnosed by flow cytometry and PCR from aqueous humor.

Background: Myeloid/NK cell precursor acute leukemia (MNKL) is a rare type of leukemia, and ocular complications have not previously been reported. We now report a patient with MNKL who developed intraocular infiltrates during follow-up.

Methods And Results: A 13-year-old boy diagnosed with MNKL developed left eye pain 3 months after starting treatment.

Japanese childhood cancer survivors' readiness for care as adults: a cross-sectional survey using the Transition Scales.

Background: Childhood cancer survivors' (CCSs') readiness for adult care has not been evaluated in Japan. We conducted a survey to examine transition barriers and facilitators in CCSs and compared the results with those of CCSs in Canada.

Methods: Participants were selected from the Heart Link mutual-aid health insurance membership directory and the Millefeuille Childhood Cancer Frontiers.

Successful treatment by coil embolization for infantile hemangioma with Kasabach-Meritt syndrome of newborn.

Infantile hemangioma (IH) is the most common tumor of infancy, and it sometimes associated with Kasabach-Meritt syndrome (KMS) characterized by anemia, intraperitoneal hemorrhage secondary to rupture, coagulopathy, jaundice, and vascular malformations involving the brain, skin, gut, and other organs. Here, we report two newborn patients having IH with KMS at birth. The first patient had a giant hemangioma in the liver, which was successfully treated with i.

Procalcitonin as a marker of respiratory disorder in neonates.

Background: Serum procalcitonin (PCT) increases in various respiratory disorders such as acute respiratory distress syndrome. Elevated PCT is also observed in healthy neonates. In this study, we investigated whether PCT is a good marker of respiratory disorder in neonates.
