Is a 500 Cell Bone Marrow Differential Count Necessary?

Is aciclovir prophylaxis necessary after bone marrow transplantation?

To assess the cost-effect relationship of aciclovir prophylaxis versus early treatment, we performed a retrospective study in 44 allogeneic bone marrow transplant recipients, who had only received aciclovir for therapeutic purposes. After bone marrow transplantation 18 herpes simplex infections occurred in 15 of the 33 patients who were seropositive for herpes simplex virus. In ten patients wit...

The Difference in Initial Leukocyte Count, Bone Marrow Blast Cell Count and CD 34 Expression in Patients with Acute Myeloid Leukemia with and without NPM1 gene Mutation

Background: Mutation in NPM1 gene has been reported to be the most common genetic mutation in de novo acute myeloid leukemia (AML). AML with NPM1 gene mutation usually presents with higher initial leukocyte and blast cell counts and negative CD34 expression. We aimed to investigate the difference of initial leukocyte counts, bone marrow blast cell counts and expression of CD34 among patients wi...

Bone Marrow Transplant (BMT) is the Main Cureavailable for Thalassamia

Introduction: The thalassamias refer to a diverse group of hemoglobin disorders characterized by a reduced synthesis of  one or more of globin chains (α,β, γ, δβ,γδβ, δ and εγδβ).The main cure available today for thalassamia is bone marrow transplantation (BMT)  from compatible donor.On December 3, 1981 a 14-month-old child with β-thalassemia major recieved BMT from his HLA-identical sister in...

Bone marrow cell count per cubic millimeter bone marrow: a new parameter for quantitating therapy-induced cytoreduction in acute leukemia.

A new technique is introduced for determining the number of bone marrow cells per cubic millimeter marrow, providing an accurate and objective means for quantitating therapy-induced cytoreduction. The method requires a correction for admixed peripheral blood in bone marrow aspirates to measure the fraction of remaining pure marrow. While cell kinetic differences between blood, aspirates, and bi...
