acute leukemia which is the most common cancer in children is a heterogeneous group of clonal malignancies. the conversion of the leukemic cell lineage during the course of the disease or later is termed lineage switch. it has been rarely reported in the literature. in leukemia lineage switch, conversions from lymphoblastic leukemia to myeloid leukemia or vice versa are reported. herein, we rep...
fuzzy expert systems are one of the most practical intelligent models with the high potential for managing uncertainty associated to the medical diagnosis. in this paper, a fuzzy inference system (fis) for diagnosing of acute lymphocytic leukemia in children has been introduced. the fuzzy expert system applies mamdani reasoning model that has high interpretability to explain system results to e...

abstract objective the incidence of childhood cancer has been increasing nearly one percent per year for the past two decades. leukemia and lymphoma are the most common types of childhood cancers. this study assessed the relation between environmental factors (hydrocarbon, agricultural toxin, insecticide) and leukemia/lymphoma in children, which was evaluated by the frequency of the parents’ ha...
introduction campylobacter jejuni is a slender, motile, non-spore-forming, helical-shaped, gram-negative bacterium. it is one of the most common causes of human gastroenteritis in the world. the aim of this study was to present a patient with acute lymphocytic leukemia (all), who was infected with campylobacter jejuni. conclusions c. jejuni should be considered in the differential diagnosis as ...
background: pediatric patients on chemotherapy are vulnerable to invasive fungal infection especially candida spices. resistance to antifungal agents has increased in candida spp., especially in non-albicans species. this study aims to assess the susceptibility of candida spp. strains isolated from children with acute leukemia less than 18 years. materials and methods: this prospective cross-se...
background: the conventional chemotherapeutic regimens which applied for treatment of acute myeloid leukemia (aml) mostly target tumor bulk but not leukemic stem cells (lscs). aberrant expression or activation of mediators such as osteopontin (opn) or pi3k/pten/akt/mtor pathway plays a key role in making prone to develop leukemia. preventing or treating cancer by curcumin (cur) has been suggest...
background: the present study was aimed to examine the possible association between methylene tetrahydrofolate reductase (mthfr) gene polymorphisms and childhood acute lymphoblastic leukemia (all) in a sample of iranian population. subjects and methods: a total of 220 subjects including 100 children diagnosed with all and 120 healthy children participated in the case-control study. the single n...
background: acute myeloid leukemia, as most cancers, results from exposure to carcinogens and an impaired inherited individual capacity to eliminate xenobiotics. the present case-control study measures the relationship between glutathione s-transferase (gst) t1 and m1 null genotypes and the risk of acute myeloid leukemia. methods: we identified the gstt1 andgstm1 genotypes by multiplex polymera...
homogeneously staining regions (hsr) or double minute chromosomes (dmin) are autonomously replicating extra-chromosomal elements that are frequently associated with gene amplifi cation in a variety of cancers. the diagnosis of leukemia patients was based on characterization of the leukemic cells obtained from bone marrow cytogenetics. this study report two cases, one with acute myeloblastic leu...
