Objective: There is no study evaluating the effect on plasma osmolality of both fluid tonicity and high fluid rate at the same time. The aim of this experimental study was to determine the change in the plasma osmolality by different fluid tonicity and rate, and to suggest the safest and the most appropriate fluids based on the plasma osmolality for medical situations requiring fluid therapy with high or maintenance rates.

Materials And Methods: The rats were randomly divided into seven groups (six rats in each group): [D] D administered at 100 ml/kg/24h; [D150] D administered at 150 ml/kg/24h; [D(½)100] D 0.

Aim: The main purpose of this study is to determine the current status of long-term follow-up (LTFU) for childhood cancer survivors and the challenges of LTFU for pediatric cancer survivors at pediatric oncology institutions in Turkey.

Material And Methods: A questionnaire was e-mailed to the directors of 33 pediatric oncology centers (POCs) registered in the Turkish Pediatric Oncology Group (TPOG). Of these 33 active TPOG institutions, 21 participated in the study and returned their completed questionnaires.

Introduction: Thrombus incidence is higher among neonates, especially in preterm infants, due to the associated additional risk factors.

Materials And Methods: The medical recordings of premature infants who had been diagnosed as having intracardiac thrombus between January 2016 and January 2019 were evaluated retrospectively. We use recombinant tissue plasminogen activator when the thrombus is relatively large compared to left atrium, pedunculated, mobile, or snake shaped.

Background: Severe congenital neutropenia is a rare disease, and autosomal dominantly inherited ELANE mutation is the most frequently observed genetic defect in the registries from North America and Western Europe. However, in eastern countries where consanguineous marriages are common, autosomal recessive forms might be more frequent.

Method: Two hundred and sixteen patients with severe congenital neutropenia from 28 different pediatric centers in Turkey were registered.

Objective: In adults and children, the duration of chemotherapy-induced neutropenia and associated complications has decreased because of the prophylactic use of granulocyte colony-stimulating factors (G-CSFs). Biosimilar G-CSFs can play an important role in reducing treatment costs in daily practice. However, some concerns regarding the efficacy and safety of new biosimilar products exist among clinicians.

We present an unusual case of hypophyseal involvement in a boy with acute lymphoblastic leukemia via magnetic resonance imaging findings. In our case, the acute lymphoblastic leukemia of the pituitary gland was accurately distinguished from a pituitary adenoma by contrast-enhanced dynamic hypophysis magnetic resonance imaging studies.

Background: Cancer survival rates and longevity of patients after therapy have significantly improved during the last few decades. Therefore, lasting protection against infections should be provided.

Procedure: A total of 162 children diagnosed with acute lymphoblastic leukemia, acute myelogenous leukemia, solid tumors, non-Hodgkin lymphoma, and Hodgkin lymphoma were enrolled in the study.

Cancer and its treatment are stressful and reduce the quality of life in children. The aim of this study was to investigate the effect of massage therapy on pain and anxiety arising from intrathecal therapy or bone marrow aspiration in children with cancer. We conducted a controlled pretest/posttest quasi-experimental study at a paediatric oncology unit in Turkey.

Papillon-Lefèvre syndrome is a rare autosomal recessive disorder caused by cathepsin C gene mutation leading to the deficiency of cathepsin C enzymatic activity. The disease is characterized by palmoplantar hyperkeratosis, periodontopathy and precocious loss of dentition, and increased susceptibility to infections. Pyogenic liver abscess is an increasingly recognized complication.

Undifferentiated embryonic liver sarcoma (UELS) is a rare highly malignant neoplasm that predominantly occurs in children between 5 and 10 years of age. The typical radiologic appearance on ultrasound and computed tomography of UELS shows a large septated mass having combined cystic and solid components. These radiographic features, however, are not specific to UELS and are shared by other more common and benign diseases of the liver.

We compared the safety and efficacy of 2 transfusion regimens in children with severe anemia (hemoglobin <5 g/dL) and without overt signs of congestive heart failure requiring transfusion of packed red blood cells (PRBCs). Forty-three patients were randomly divided into 2 groups: group A and group B. The transfusion regimens consisted of continuous infusion of PRBC at a rate of 1 mL/kg/h for group A and 3 mL/kg/h for group B.

Background: Amitriptyline is one of the major tricyclic antidepressants, and the data on amitriptyline poisoning in children are limited.

Objectives: To present our experiences with amitriptyline poisoning in children, particularly with regard to its effects on electrocardiogram (ECG) and relation with clinical status.

Methods: Clinical, laboratory, and electrocardiographic findings in 52 children admitted with amitriptyline poisoning were reviewed.

Isolated noncompaction of the ventricular myocardium is an uncommon disorder characterized by an excessively prominent trabecular meshwork seen in the early period of embryogenesis. The clinical presentation of noncompaction includes a high prevalence of heart failure, thromboembolic events and arrhythmias. Echocardiography is the procedure of choice for the diagnosis of noncompaction.

Corticosteroids have been widely used in the treatment of idiopathic thrombocytopenic purpura (ITP). We evaluated the late side effects of high-dose methylprednisolone (HDMP) therapy on bone metabolism in children with ITP. Twenty-eight children with acute ITP treated with HDMP (30 mg/kg/d for 3 d then 20 mg/kg/d for 4 d) and 28 controls were enrolled in the study.
