Background:
Patients treated for pediatric malignancy are at high risk of parenterally transmitted viral hepatitis.
Objectives:
To detect the seroprevalence of hepatitis B and C viral infections in children with Acute Lymphoblastic Leukemia & identify some variables that could affect its
prevalence in these patients.
Patients and Methods:
One hundred fifty pediatric acute lymphoblastic leukemia patients, presented to Children Welfare Teaching Hospital, Baghdad, during the period from March 11th
2007 to July 31st 2007 were enrolled in this study; they were 103 males, 47 females, aged (2.25 months- 16 years). Sera of these patients were investigated for hepatitis
markers including HBsAg and Anti HCV antibody.
Results
The majority of patients were from Baghdad 104 (69.33%). Almost all children received 3 doses of hepatitis B vaccine according to the national Iraqi vaccination
schedule & 111 (74%) of them received another course of vaccination during their admission to the oncology unit at CWTH. Screening for hepatitis B virus infection was positive in 54 (36%) of cases while for hepatitis C virus infection was positive in 4 (3.25%) of cases.
Conclusion
Multiple blood transfusions and prolonged duration of observation of patients showed significant statistical impact on the incidence of HBV infection.
Superconducting compound Bi2Sr2-xYxCa2Cu3O10+δ were Synthesized by method of solid state reaction, at 1033 K for 160 hours temperature of the sintering at normal atmospheric pressure where substitutions Yttrium oxide with Strontium. When Y2O3 concentration (0.0, 0.1, 0.2, 0.3, 0.4 and 0.5). All specimens of Bi2Sr2Ca2Cu3O10+δ superconducting compounds were examined. The resistivity of electrical was checked by the four point probe technique, It was found th
The existing investigation explains the consequence of irradiation of violet laser on the structure properties of MawsoniteCu6Fe2SnS8 [CFTS] thin films. The film was equipped by the utilization of semi-computerized spray pyrolysis technique (SCSPT), it is the first time that this technique is used in the preparation and irradiation using a laser. when the received films were processed by continuous red laser (700 nm) with power (>1000mW) for different laser irradiation time using different number of times a laser scan (0, 6, 9, 12, 15 and 18 times) with total irradiation time (0,30,45,60,75,90 min) respectively at room temperature.. The XRD diffraction gave polycrysta

The effects of gamma irradiation on structure of HgBa2Ca2Cu2.4Ag0.6O8+δ samples were characterized using X-ray diffraction. It was concluded that there effect on structure by gamma irradiation. Scherrer, crystallization, and Williamson equations were applied based on the X-ray diffraction diagram and for all gamma doses, to calculate crystal size, strain, and degree of crystallinity. I
