Background: Lymphoblastic lymphomas (LBL) are neoplasms of precursor T cells and B cells, or lymphoblasts. The term lymphoblastic lymphoma has been used to describe predominantly lymph node– based disease; however, clinical distinction between LBL and acute lymphoblastic leukemia (ALL) has been arbitrary and has varied among different studies and institutions
Objectives: To determine the frequency of LBL among all Non-Hodgkin’s lymphoma (NHL) patients in children and to study the clinical and pathological features of LBL and assess the treatment outcome.
Methods: A retrospective study included 28 children with newly diagnosed LBL (based on morphology) below the age of 14 years over 8 years period from January 1st, 2000 to December 31st, 2007 All the patients except one were treated by modified Medical Research Council UK National Randomized Trial For Children and young Adult with Acute Lymphoblastic Leukemia (MRC UKALL) regimen, one patient was misdiagnosed as B-cell NHL and treated with United Kingdom Children’s Cancer Study Group (UKCCSG) Non-Hodgkin’s Lymphoma protocol.
Results: LBL forms 28/376 (7.1%) among NHL diagnosed in Children Welfare Teaching Hospital (CWTH) in the same period. The median age was 8.95 years (range 2 to 13.25 years) with male to female ratio of 3.7:1. Lymphadenopathy was present in 22 (78 .6%) of patients. The median duration of onset of symptoms was 7.25 months (range 1 week to 18 months). In response to treatment, 20 (71.4%) patients achieved complete remission (CR), 1 (3.6%) died during induction and 7 (25%) patients were non-responder (4 died and 3 abandoned). Of the 20 patients who achieved complete remission (CR); thirteen (46.4%) remained in continuous complete remission with a median follow up of 32.3 months, 3 (10.7%) patients died while in
CR in an average of 16.6 weeks, 2 (7.1%) patients abandoned treatment and 2 (7.1%) patients relapsed.
Conclusion: The study showed a low frequency of LBL in comparison with other studies which might be due to inadequate diagnostic facilities which differentiate LBL from other types of NHL, low survival rate might be due to advanced stages at presentation in addition to abandonment of treatment in some patients
Described the Arabic language being of genius sets by top models of eloquence , rhetoric and clarity of sounds and developments Moreover , it is an important element of our existence and our identity and our survival . That my methods and best in teaching Arabic language what has pursued the easiest ways to learning and teaching and helped learners to be aware of the function linguistic information , and they need it and its impact on their lives , and contributed to unleashing the potential of activism and led them to make the effort to apply them in the form of examples and uses of new life , as well as fits are the capabilities and tendencies of different learners , so the goal of current research into the importance of the curriculum

This research entitled "Spatial Scale of The Military Operations in International Armed Conflicts". Armed conflict, whether international or non-international is a non-fixed term or spatial scale, when armed conflict brakes out it would be impossible to predict the expansion of combat operations by land, sea and air, but each party to armed conflict has the obligation to ensure respect for international humanitarian law in this regard. This research is limited to the study of rules of international humanitarian law for determining the spatial scale for each theater of war or armed conflict and aims to determine the scope of military operations in respect of armed forces, means and methods of warfare used in it, to clarify the concept of

Among the issues that preoccupied ancient and modern grammarians is the phenomenon of grammatical disagreement among grammarians and their differences in many grammatical issues that many of them go back to the phenomenon of dialectical difference, so this filled our thinking with a lot of things that led us to look at the side of the reasons for this grammatical difference, and here lies the significance of research to know that it is a linguistic phenomenon dealing with the living language used among the Arabs and linguistic phenomena that reflect linguistic reality as well. Thus our chagrin determination in research and investigation in this issue is the scarcity of dialectical studies at the compositional grammar side, and the lack o

This study investigated the optimization of wear behavior of AISI 4340 steel based on the Taguchi method under various testing conditions. In this paper, a neural network and the Taguchi design method have been implemented for minimizing the wear rate in 4340 steel. A back-propagation neural network (BPNN) was developed to predict the wear rate. In the development of a predictive model, wear parameters like sliding speed, applying load and sliding distance were considered as the input model variables of the AISI 4340 steel. An analysis of variance (ANOVA) was used to determine the significant parameter affecting the wear rate. Finally, the Taguchi approach was applied to determine
