Differential expression pattern of protein markers for predicting chemosensitivity of dexamethasone-based chemotherapy of B cell acute lymphoblastic leukemia.

Dexamethasone is considered as a direct chemotherapeutic agent in the treatment of pediatric acute lymphoblastic leukemia (ALL). Beside the advantages of the drug, some problems arising from the dose-related side effects are challenging issues during the treatment. Accordingly, the classification of patients to dexamethasone sensitive and resistance groups can help to select optimizing the therapeutic dose with the lowest adverse effects particularly in sensitive cases.

Secondary ALL after Successful Treatment of Ewing's Sarcoma: A Case Report.

Treatment with intensification of chemotherapy using alkylating agents and Topoisomerase II inhibitors and radiotherapy has improved the outcome of patients with solid tumors such as Ewing's sarcoma. However, there are several reports of secondary malignancy following treatment of these tumors. In this article, we describe a 12 years old girl with ALL who had Ewing's sarcoma when she was 8 years old and underwent successful treatment but after two and half years at 12 years old, she came back with pallor and muscular pain.

Identification of potential predictive markers of dexamethasone resistance in childhood acute lymphoblastic leukemia.

Response to dexamethasone (DEXA), as a hallmark drug in the treatment of childhood acute lymphoblastic leukemia (ALL), is one of the pivotal prognostic factors in the prediction of outcome in ALL. Identification of predictive markers of chemoresistance is beneficial to selecting of the best therapeutic protocol with the lowest effect adverse. Hence, we aimed to find drug targets using the 2DE/MS proteomics study of a DEXA-resistant cell line (REH) as a model for poor DEXA responding patients before and after drug treatment.

Successful Control of Massive Bleeding in a Child with Burkitt's Lymphoma via a Biosimilar Recombinant Activated Factor VII (AryoSeven™).

We describe a case of a 4-year-old girl with Burkitt's lymphoma, who suffered from a massive gastrointestinal hemorrhage 3 days after chemotherapy. In spite of applying the common practice in correction of coagulopathy, thrombocytopenia persisted and bleeding became life-threatening. In the present case report, we report a successful control of bleeding with a single-dose administration of a biosimilar recombinant activated human factor VII (AryoSeven).

Intra-Abdominal Lymphangiomatosis with Bone Marrow Involvement in a 7-Year Old Girl: A Case Report.

Lymphangiomas are rare tumors. When they occur at different locations, they are referred to as lymphangiomatosis. Here we describe a case of lymphangiomatosis presenting with chronic diarrhea and failure to thrive.
