Article Synopsis
  • Silent inactivation (SI) of L-asparaginase (ASP) is a process where antibodies decrease ASP activity in patients without allergic reactions, affecting those with acute lymphoblastic leukemia (ALL) negatively.
  • A clinical trial in Japan, named ALL-ASP19, measured ASP activity (ASA) to identify SI in newly diagnosed ALL patients, enrolling 110 participants but analyzing 66 after exclusions.
  • The study found that the incidence of SI was low (4.5%) in Japan compared to other countries, and while all SI patients had antibodies, not all with antibodies experienced SI, indicating the importance of measuring ASA levels for effective treatment.

Oral care for patients with severe physical and intellectual disabilities is important to prevent the development of systemic diseases and maintain or improve their health. Foreign bodies accidentally aspirated into the respiratory tract can cause critical problems. To our knowledge, this is the first case report of aspiration of a broken tip of a disposable saliva ejector in a patient with severe physical and intellectual disabilities.

Immunosuppressive therapy (IST) is the first-line treatment for patients with aplastic anemia (AA) who require blood transfusion when a human leukocyte antigen-matched related donor is unavailable. However, the proportion of patients with AA who are refractory to IST remains high (30%). IST in combination with eltrombopag has been studied in adults, but its efficacy and safety in children have not been established.

Article Synopsis
  • The study examined the use of C-reactive protein to albumin ratio (CAR) as a prognostic marker in adult T-cell leukemia-lymphoma (ATL), analyzing data from 68 patients diagnosed between 2013 and 2017.
  • Results showed that higher CAR levels were linked to worse overall survival, with patients having a CAR above 0.553 surviving a median of 3.94 months compared to 8.37 months for those below this threshold.
  • The findings suggest that CAR could serve as a simple and valuable independent prognostic marker, particularly in patients undergoing chemotherapy.

Introduction: There is some evidence that Bordetella pertussis (B. pertussis) can co-infect with viral respiratory infections in young infants.

Methods: B.

Background: Rearrangements of chromosome 8q24/MYC (8q24/MYC-r), resulting from t(8;14)(q24;q32), t(2;8)(p11;q24), or t(8;22)(q24;q11), are mainly associated with Burkitt lymphoma/leukemia (BL) and rarely observed in patients with B-cell precursor acute lymphoblastic leukemia (BCP-ALL). The characteristics of BCP-ALL with 8q24/MYC-r are poorly understood.

Procedure: A retrospective nationwide study of data from patients with pediatric BCP-ALL with 8q24/MYC-r in Japan was conducted to clarify the clinical and biological characteristics associated with 8q24/MYC-r BCP-ALL.

Background: Ploidy is a highly significant prognostic factor for pediatric acute lymphoblastic leukemia (ALL). Children with hypodiploid ALL have poor outcomes despite current intensive chemotherapy. Little has been investigated with regard to hypodiploid ALL in Japanese children.

Background: Adhesive strapping for umbilical hernia has been re-evaluated as a promising treatment. We evaluated the influence of adhesive strapping on the outcome of umbilical hernia.

Methods: We retrospectively evaluated patients with umbilical hernia referred to the present institution from April 2011 to December 2015.

In a previous study of childhood acute lymphoblastic leukemia (ALL) by the Kyushu-Yamaguchi Children's Cancer Study Group, ALL-96, we achieved a 72.1 % 5-year event-free survival (EFS) and an 84.8 % 5-year overall survival (OS).

We here report a 2-year-old female with relapsed acute myeloid leukemia (AML) with MLL gene rearrangement in the bone marrow and central nervous system. The 3'-RACE (Rapid Amplification of cDNA Ends) method identified the MLLT10 gene as a fusion partner of the MLL gene. The patient was complicated with hemophagocytic lymphohistiocytosis (HLH) and invasive aspergillosis (IPA) after re-induction treatment with FLAG-IDA following etoposide, cytarabine, and mitoxantrone.

We describe a case of a 5-year-old girl with central nervous system relapse of neuroblastoma after high-dose chemotherapy and autologous stem cell transplantation. Although the brain metastasis was surgically removed, she had a second relapse in the same region with leptomeningeal dissemination despite receiving irinotecan. Administration of temozolomide in addition to irinotecan led to her third complete response and the patient has been in complete response for >24 months.

We describe a 5-year-old female with acute lymphoblastic leukemia (ALL) who suffered from cytomegalovirus (CMV) retinitis during maintenance therapy consisting of 6-mercaptopurine (6-MP) and methotrexate (MTX) with pulses of vincristine (VCR) and dexamethasone (DEX). Administration of anticytomegaloviral drugs led to a complete regression of active retinitis. Her low CD4 positive T cells and serum immunoglobulin G (IgG) recovered when maintenance therapy was resumed without VCR and DEX.

Anaplastic lymphoma kinase (ALK) positive anaplastic large cell lymphoma (ALCL) is usually associated with a favorable prognosis. We describe an 11-year-old girl patient with ALK positive ALCL bearing t(2;5)(p23;q35) and t(8;17)(q24;q25) translocations who had an aggressive clinical course despite various combinations of intensive chemotherapy. Southern blot analysis identified C-MYC rearrangement.

Background: Osteopathy is one of the common initial symptoms of acute lymphocytic leukemia (ALL) in children and adolescents, but multiple osteolysis accompanied by hypercalcemia is rarely observed.

Procedure: We treated a 14-year-old female who had multiple osteolytic lesions and hypercalcemia at initial onset of ALL. In this case we examined some humoral factors, which are known to associate with hypercalcemia in malignancies.
