Comparison of Bone Marrow Biopsy and Flow Cytometry in Demonstrating Bone Marrow Metastasis of Neuroblastoma.

Objective: This study aimed to compare bone marrow aspirate (BMA) multicolor flow cytometry (MFC) analysis and bone marrow biopsy (BMB) in detecting bone marrow (BM) involvement in children with neuroblastoma (NB) at diagnosis and during follow-up.

Materials And Methods: A total of 132 BM samples from 39 patients (M/F ratio: 19/20; median age: 38 months) with neuroblastoma were simultaneously obtained for evaluation. The samples were investigated for BM involvement using BMB and MFC.

The effect of gene polymorphisms ( rs7799039 and rs1137101) on febrile neutropenia.

Background And Aim: Leptin is mainly produced in adipose tissue and released into systemic circulation. Leptin and its receptor LEPR activate the Janus kinase/signal transducers and activators of transcription signaling cascade and increase cytokine discharge. In our study, we aimed to examine the role of gene () rs7799039 and LEPR rs1137101 polymorphisms on the susceptibility for febrile neutropenia (FEN) attacks and their relationship with clinical findings during the course of FEN.

Objective: This study aimed to evaluate the impact of psychosocial support videos provided by the community on the attitudes of pediatric oncology patients aged between 10 and 18 years toward their illness and treatment-related symptoms.

Data Sources: This prospective randomized controlled study was conducted with 52 pediatric oncology patients aged between 10 and 18. The data were collected using the Information Form, Child Attitude Towards Illness Scale (CATIS), and Memorial Symptom Assessment Scale (MSAS).

Neonatal portal vein thrombosis: risk factors, diagnosis, treatment recommendations and review of the literature.

Background: Neonatal portal vein thrombosis (PVT) is currently more commonly encountered as a result of advances in diagnostic tools and increase in invasive interventions.

Methods: In this study, 11 premature and 12 term infants diagnosed with PVT were retrospectively evaluated for clinical and laboratory characteristics, umbilical catheterization procedure, PVT location, risk factors, treatments, and long-term outcomes.

Results: Median age of the patients at diagnosis was 10 days (range 3-90 days), and 69.

A comparison of hypersensitivity reactions between intravenous and intramuscular applications of native asparaginase in children with acute lymphoblastic leukemia.

Introduction: Asparaginase is an indispensable drug in treating childhood acute lymphoblastic leukemia (ALL). Hypersensitivity reactions (HSR) are the most common side effects and interfere with the antineoplastic activity of the drug. This study aims to compare the intramuscular (IM) and intravenous (IV) administration routes of Native Escherichia coli Lasparaginase (L-ASNase) in terms of hypersensitive reactions.

Prognostic Factors and Long-term Outcomes in 41 Children With Primary Hemophagocytic Lymphohistiocytosis: Report of a Single-center Experience and Review of the Literature.

Hemophagocytic lymphohistiocytosis (HLH) is a rare life-threatening hyperinflammatory syndrome with diverse clinical manifestations leading to major diagnostic and therapeutic difficulties. This study aimed to evaluate clinical manifestations, prognostic factors, and long-term outcomes in children with primary HLH. Forty-one patients diagnosed with primary HLH were retrospectively evaluated for patient characteristics, HLH gene mutations, clinical and laboratory manifestations, prognostic factors, and long-term outcomes.

The effect of granulocyte colony-stimulating factors on survival parameters in pediatric patients with acute lymphoblastic leukemia: A retrospective study.

Objective: There is a paucity of data concerning the use of granulocyte colony-stimulating factors (G-CSFs) in pediatric patients with acute lymphoblastic leukemia (ALL). The aim of the present study was to evaluate the effect of G-CSF use on relapse-free and overall survival in 358 consecutive, newly diagnosed pediatric ALL patients uniformly treated at the same institution between April 2012 and April 2020.

Materials And Methods: Patients were evaluated in two separate periods, based on the G-CSF treatment approach.

Association of mannose-binding lectin 2 (MBL2) and suppressor of cytokine signaling-1 (SOCS1) gene variants in children with febrile neutropenia.

Introduction: Febrile neutropenia (FEN) was reported in patients with solid malignancies at a rate of 5-10% and in patients with hematological malignancies at a rate of 20-25%. In our study, we aimed to investigate the effects of mannose-binding lectin 2 (MBL2) (rs1800450) and suppressor of cytokine signaling-1 (SOCS1) (rs33989964) gene variants on patients with FEN.

Methods: A total of 123 patients who applied to pediatric emergency department between December 2019-12/2020 included in the study.

Importance of mannose-binding lectin2 polymorphism () in infections in children.

Purpose: Mannose-binding lectin (MBL) is a serine protease belonging to the collectins and an important factor in the inherited immune system. We aimed to reveal the distribution of different genotypes in patients diagnosed with acute bronchiolitis and pneumonia.

Material And Methods: A total of 147 patients who applied to Paediatric Emergency between 01.

Glucose 6 phosphate dehydrogenase deficiency: A single-center experience.

Objective: This study aims to evaluate the demographic information, clinical and laboratory findings of patients with glucose 6 phosphate dehydrogenase deficiency.

Material And Methods: We collected data by reviewing files and electronic records of 65 patients with glucose 6 phosphate dehydrogenase deficiency under the age of 18 years who were followed up in our clinic between 2007 and 2019. Demographic, clinical, and laboratory features, family history, complications of the disease, and history of splenectomy and cholecystectomy were evaluated.

Safety and efficacy of deferasirox in patients with transfusion-dependent thalassemia: A 4-year single-center experience.

This study was organized to determine the efficacy and safety of deferasirox (DFX) in reducing the SF of patients with transfusion-dependent thalassemia (TDT). This is a retrospective, descriptive study of 101 transfusion- dependent patients with thalassemia major who were followed for 48 months. Twenty-nine patients who used an alternative chelator either alone or combined, who were not compliant to the treatment, changed the drug due to adverse reactions, and had multiple transfusions and did not complete 4 years of DFX use were excluded.

Burkitt Leukemia With Precursor B-Cell Immunophenotype and Dual Translocation of t(14;18) and t(8;14) in a Child: Case Report and Review of the Literature.

Background: Burkitt leukemia (BL) with the precursor B-cell immunophenotype is a rarely reported condition. The prognosis of such patients is similar to that of classic BL. However, the combination of chromosomal translocations associated with bcl-2 and c-myc rearrangement has a poor prognosis.

Hemophagocytic Lymphohistiocytosis Associated With Visceral Leishmaniasis.

This is the report of a 2-year-old boy who presented with fever, cytopenia, and splenomegaly. The patient was diagnosed with hemophagocytic lymphohistiocytosis (HLH) and treated with HLH-2004 protocol. Repeated bone marrow aspiration showed amastigotes on follow-up.

Serum level of vitamin D and trace elements in children with recurrent wheezing: a cross-sectional study.

Background: We aimed to show the relationship between recurrence of wheezing and serum levels of vitamin D, zinc, and copper in wheezy children compared with a healthy group.

Methods: In this cross sectional study, seventy-three children with wheezing and seventy-five controls were included without a follow-up period. The clinical characteristics of the children were assessed, the asthma predictive index and temporal pattern of wheeze were determined.
