Article Synopsis
- During the COVID-19 pandemic lockdown, the study assessed respiratory viral infections in children with cancer, highlighting their clinical impact.
- Of the 265 episodes evaluated, human rhinovirus/enterovirus was the most common pathogen identified, with significant complications noted, including a higher rate of lower respiratory tract infections.
- The findings emphasize the necessity for quicker detection and treatment of respiratory viruses to prevent severe outcomes in this vulnerable population.
According to the World Health Organization (WHO), leishmaniasis is a zoonotic/anthroponotic parasitic disease endemic in 99 countries. It is estimated that approximately 12 million people are infected with Leishmania spp. and 350 million people live at risk.

Effective and well-tolerated treatment options for relapsed-refractory immune cytopenias are limited. In this study, the aim was to evaluate the efficacy and safety of sirolimus in this disease group within the paediatric age group.

- Intravascular fasciitis (IF) is a rare but benign condition that occurs in the fascia surrounding small to medium blood vessels.
- An 8-year-old boy with swelling in the groin was found to have a deep vein thrombosis but later developed an unusual mass, leading to the discontinuation of treatment with anticoagulants.
- After surgery and examination, the mass was identified as intravascular fasciitis, highlighting the need for doctors to differentiate IF from more serious conditions like sarcoma and thrombosis.
A 4-year-old boy presented with acute-onset autoimmune cytopenia with severe, persistent lymphopenia, autoimmune thyroiditis, elevated IgE and glucose 6-phosphate dehydrogenase enzyme deficiency. In immunologic evaluation, lower T, B and natural killer cells and higher levels of adenosine deaminase (ADA) metabolites were observed. The compound heterozygous novel gene mutations causing ADA deficiency were detected.

For patients with hemoglobinopathies, it is well-established that hematopoietic stem cell transplantation provides a complete cure, but the literature on its role for those with Hb Hammersmith is limited. A seven-month-old girl who was examined for anemia and splenomegaly was followed up for congenital hemolytic anemia.

In this multicenter study, we aimed to research the frequency of central nervous system (CNS) thrombosis occurring during treatment, hereditary and acquired risk factors, clinical and laboratory features of patients with thrombosis, treatment approaches, and thrombosis-related mortality and morbidity rates in pediatric ALL patients.
Procedure: Pediatric patients who developed CNS thrombosis during ALL treatment from 2010 to 2021 were analyzed retrospectively in 25 different Pediatric Hematology Oncology centers in Türkiye.
Objective: This study aimed to evaluate systemic thrombolysis experiences with recombinant tissue plasminogen activator (rtPA).
Materials And Methods: Retrospective data were collected from 13 Turkish pediatric hematology centers. The dose and duration of rtPA treatment, concomitant anticoagulant treatment, complete clot resolution (CCR), partial clot resolution (PCR), and bleeding complications were evaluated.
Background: Sitosterolemia is a rare lipid disorder caused by mutations in adenosine triphosphate-binding cassette genes (ABCG) 5 and 8.
Objective: To evaluate the phenotypic/genotypic features of sitosterolemia in a group of Turkish patients.
Methods: Seven probands with unexplained hematologic abnormalities and their 13 relatives were enrolled.

Factor X (FX) is the component of both extrinsic and intrinsic coagulation cascade and is the first enzyme of the common pathway which results in thrombus. Congenital FX deficiency (FXD) is an extremely rare coagulation defect. In this study, we aimed to investigate the clinical and laboratory data of the patients diagnosed with FXD.
