Cervical lymphadenopathy is a relatively common finding in pediatric age group and is caused by a wide spectrum of diseases from transient infections to malignancies especially lymphomas. The present study was aimed at evaluating the diagnostic performance of grey-scale ultrasonography, color Doppler ultrasonography and power Doppler ultrasonography in(More)
Cryptosporidiosis caused by Cryptosporidium spp. is an important parasitic disease that can be life-threatening for children and immunocompromised patients. This systematic review and meta-analysis was designed to determine the prevalence rate of Cryptosporidium infection and related risk factors among the Iranian general population. We searched electronic(More)
OBJECTIVE(S) Non- Hodgkin lymphoma (NHL) and acute lymphoblastic leukemia (ALL) are two main hematological malignances which have been driven from lymphoid tissue. Genetic polymorphisms in tumor necrosis factor-α (TNF-α) -308 and lymphotoxin-α (LT-α) +252 may affect their transcription and expression which leads to their high plasma level. The frequency of(More)
The goal of this study was the evaluation of specific markers of myocardial injury that includes CK-MB and troponin I in major thalassemic patients. Regular blood transfusion is the main treatment in major thalassemia. One of the most important complications of regular blood transfusion is iron overload that eventually involves many organs like heart and(More)

OBJECTIVE Rare disease. BACKGROUND Leukemias are among the most common childhood malignancies. Acute lymphoblastic(More)
OBJECTIVE To examine all evidence about Microsporidia infection in vertebrate/invertebrate hosts and Iranian populations distributed in different regions of the country. METHODS All published articles up to December 2015, including descriptive and cross-sectional studies related to the prevalence and genotyping of Microsporidia infection in Iran, was(More)
Although neuroblastic tumors are the most prevalent solid tumors, little is known about the genetic basis underlying their progression. The prognostic role for the MYCN gene in neuroblastic tumors is irrefutable. The aim of this study is to identify the frequency of MYCN gene amplification and its relationship with clinicopathological and prognostic factors(More)
Gene fusions are observed in abnormal chromosomal rearrangements such as translocations in hematopoietic malignancies, especially leukemia subtypes. Hence, it is critical to obtain correct information about these rearrangements in order to apply proper treatment techniques. To identify abnormal molecular changes in patients with leukemia, we developed a(More)
Cryptosporidiosis is a relatively uncommon disease in healthy individuals but could be potentially worrisome in immunocompromised patients. This study aimed to evaluate Cryptosporidium infection in children with cancer undergoing chemotherapy. A case-control study was conducted in 132 children with cancer undergoing chemotherapy and 132 non-cancer controls.(More)
Optimized conditions, validation and practical applications of a new, rapid and specific fluorometric method for the determination of deferiprone (DFP) in urine and serum samples are reported. The proposed method, which is based on the formation of a luminescent complex with Tb(3+) ion, is evaluated in terms of linearity, accuracy, precision, stability,(More)
