Introduction: Multiple myeloma (MM) is a B-cell lymphoproliferative disease in which the bone marrow microenvironment plays an important role in pathogenesis. The T helper (Th-17) cell plays an important role in the development of cancer by releasing pro-inflammatory cytokines such as IL-17A and IL-17F. Th-17 cells have been studied in a variety of solid tumors, as well as few hematological malignancies, including acute myeloid leukemia, non-Hodgkin lymphoma, and monoclonal gammopathy of unknown significance.

Introduction: While acute kidney injury (AKI) in pregnancy is currently a rare entity in developed countries, it is still a common occurrence in developing countries, representing a major cause of maternal and fetal morbidity and mortality. Scarce data are published regarding pregnancy-related acute kidney injury (PRAKI) in Middle Eastern and African countries. The aim of this work is to report on the frequency, the underlying causes, and the outcomes of patients with PRAKI in an Egyptian tertiary care hospital.

Pregnancy-related acute kidney injury (PRAKI) particularly on top of preeclampsia (PE) represents a major cause of maternal and fetal morbidity and mortality. Reliable diagnostic tools are needed to further evaluate the diagnosis and prognosis of PRAKI. Our objective was to study the diagnostic and prognostic value of angiogenic markers (e.

Background: Cyclin D1 (CCND1) regulates cell cycle progression during the late G1 and S phase and takes part in methotrexate metabolism. It was hypothesized that CCND1 gene polymorphism affects acute lymphoblastic leukemia (ALL) development, prognosis and may relate to methotrexate cytotoxicity.

Subjects And Methods: This study included 50 ALL patients and 50 healthy controls, CCND1 G870A polymorphism was studied in all items using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and evaluated methotrexate cytotoxicity for ALL patients using liver function tests before and after methotrexate treatment.

An improved classification technique is presented to identify automatically the acute lymphatic leukemia (ALL) subtypes. An adaptive segmentation procedure is performed on peripheral blood smear images to extract the main features (10 geometric features) from the segmented images of white blood cell (WBC), nucleus, and cytoplasm. To show the importance of the different extracted features for the diagnostic accuracy, a comprehensive study is made on all the possible permutation cases of the features using powerful classifiers which are K-nearest neighbor (KNN) at different metric functions, support vector machine (SVM) with different kernels, and artificial neural network (ANN).

Nucleophosmin (NPM1) and fms-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) gene mutations represent the most frequent molecular aberrations in patients with cytogenetically normal-acute myeloid leukemia (CN-AML). We analyzed the prognostic impact of these mutations and their interactions in adults with CN-AML. NPM1 mutation (NPM1mut) and FLT3-ITD mutation (FLT3-ITD+) were analyzed by polymerase chain reaction and GeneScan assays of bone marrow samples obtained from newly diagnosed 104 CN-AML patients.

Aim: To assess the prognostic role of myeloid transcription factor gene CEBPA (CCAAT/enhancer binding protein-α), a novel gene involved in leukemia in Egyptian adults AML.

Materials And Methods: Screening for CEBPA mutations was assessed using PCR-single-strand conformation polymorphism (PCR-SSCP) in pretreatment bone marrow samples from 55 newly diagnosed adult AML.

Results: CEBPA mutations were found in 11 (20%) of 55 AML patients.

Cytomorphology, cytochemistry, immunophenotyping, in addition to cytogenetic and molecular analyses have specific roles in the diagnosis and management of acute leukemias. This work was designed as a comparative study of different available methods for diagnosis of acute leukemia. The study comprised 47 cases with acute leukemia (21 cases with ALL and 26 cases with AML).

Multidrug resistance (MDR) is still a major obstacle to chemotherapy success in acute myeloid leukemia (AML) and to a less extent acute lymphoblastic leukemia (ALL). Recent studies have shown that the expression of certain gene products mediate the development of resistance to chemotherapeutic agents. The most well characterized of these genes is the multidrug resistance gene MDR-1.
