السلام عليكم يا اهل المنتدى
اسفه للانقطاع بس ما كان في كنكشن اليومين اللي فاتت شكله فاتتني اسئله مهمه
بالنسبه لسؤال 70 مع انه ينقصنا نعرف الdifferential count وperipheral blood pictureان شاء الله الاجابات تكون:
1- C
2- B
3- A
4- A
هذه الحاله محيره لانه حسب الsevere infectionنقول leukomoid reactionبس الLAP score ناقص
:sm195::sm195:

بالنسبة للأنسة بهلول:

two diseases are similar in blood film picture: the chronic myelocytic leukemia and the neutrophilic leukemoid reaction, but they can be discriminated by the following:
1- LAP score in CML is reduced, while in leukemoid reaction is increased
2- Usually a karyotype shows the Ph (philadelphia chromosome) in CML
3- Doing FISH technique to detect the ABL/BCR fusion gene will be positive in 95% of the CML cases. or doing RT-PCR to detect the chimeric m-RNA.
4- in CML there is usually basophilia associated with the case as all other chronic myeloproliferative diseases, where as in leukemoid reaction there is no basophilia.
Also eosinophilia can be associated with CML.
5- the course of the diseaes in CML is more chronic and is persistent
6- massive splenomegaly is oftenly associated with CML

thank you for your attention
