Invasive fungal infections, including hepatosplenic infections (HSFI), cause significant morbidity and mortality in children with leukemia. There are not enough data to support for the best approach diagnosis of HSFI children, nor treatment.In this multicentric study, we assessed demographic data, clinical radiologic features, treatment, outcome 40 leukemia from 12 centers.All cases were radiologically diagnosed abdominal ultrasound, which was performed at a median 7 days, febrile...
Budd–Chiari syndrome is a heterogeneous group of disorders characterized by hepatic venous outflow obstruction. Although there are no guidelines for treatment patients with syndrome, thrombolytic therapy may be useful in acute syndrome. In this report, boy due to membranous obstruction the inferior vena cava treated systemic and local administration recombinant tissue plasminogen activator described. We would like emphasize role fibrinolytic these patients.
This study was undertaken to determine the prevalence of Factor V 1691 G-A and PT 20210 mutations in Turkish children with leukemia. We genotyped 135 pediatric leukemia patients for these mutations. Eleven (8%) were heterozygous FV mutation. Seven (5,1%) carried Of patients, only three had thrombotic event, none which two mutations, is common population. Our findings revealed a controversial compared previous reports, needs further investigation.
OBJECTIVES: The CCAAT/enhancer-binding protein-alpha (CEBPA) is lineage-specifi c transcription factor in the hematopoietic system.In this study, we aimed on clinical features and prognostic signifi cance associated with CEBPA mutations 30 pediatric patients acute leukemia.METHODS: In addition, association between found variants of Ten-Eleven-Translocation 2 (TET2), Kirsten rat sarcoma viral oncogene homolog (KRAS), Casitas B-cell lymphoma (CBL), FLT3 (Fms-Related Tyrosine Kinase), JAK2...
Background: Platelet-rich plasma (PRP) has been widely used to improve wound healing and tissue repair.The objective of this study was assess a cycle freezing/thawing its effect in the amount growth factors PRP.Materials methods: After preparation PRP using standard methods, samples were equally divided into two groups: The first group activated by adding 10% calcium gluconate, while second cryopreserved at -80°C for 24 hours.Enzyme-linked immunosorbent assay aliquots measure concentrations...
Anticardiolipin (aCL) antibodies are associated with thrombosis and have an important role in the etiology of diseases such as stroke myocardial infarction whose etiologies were based on thrombosis. H. pylori has been proposed to be responsible for pathophysiology some including stroke, infarction, thrombosis, autoimmune diseases. From this point view, we hypothesized a possible relationship between infection aCL initially aimed determine prevalence antibody positivity children...
Hemoglobin M Saskatoon (s63 His>Tyr(C-T)) is a rare hemoglobin variant that was first reported in Japan, followed by the US, Indonesia, Algeria, Russia, India, and Germany [1-8].
