    Objective: In this study, we aim to demonstrate that measurement of the malondialdehyde (MDA) level in the umbilical cord blood of newborn infants born via cesarean section (C/S) and normal vaginal delivery (NVD) is indicative of oxidative stress during the perinatal period. Methods: The study was conducted at Bakirkoy Training and Research Hospital between January 2006 and April 2006 on 15 newborns born via elective C/S, 15 newborns born via emergency C/S, and 15 newborns born via normal vaginal delivery. Complete blood count, total bilirubin, glucose, creatinine phosphokinase (CPK), uric acid, iron, blood gas, and malondialdehyde levels were measured in the umbilical cord blood Findings: Malondialdehyde levels in the umbilical cord blood in the emergency C/S and NVD groups were found to be statistically and significantly higher than those in the elective C/S group. In the emergency C/S group, it was determined that the malondialdehyde level increased as the oxygen saturation of the umbilical cord blood increased. In the NVD group, a positive correlation was detected between the total bilirubin and malondialdehyde levels in the umbilical cord blood. In the emergency C/S group, the malondialdehyde level was recorded to be high in the infants with high level of uric acid in the umbilical cord blood. Conclusion: We concluded that the malondialdehyde level in umbilical cord blood could serve as an indication of perinatal oxidative stress and that it could thus help in preventing permanent damage.

    Serum zinc levels in children of 0-24 months diagnosed with pneumonia admitted to our clinic
    (E-Century Publishing Corp, 2011) Arica, Secil; Arica, Vefik; Dag, Huseyin; Kaya, Aysen; Hatipoglu, Sami; Fenercioglu, Aysen; Karatekin, Guner
    Aim: We have planned to study the relationship between zinc (Zn) plasma levels, as well as pneumonia criteria, and zinc in healthy children younger than 2 years of age compared to pediatric patients diagnosed with pneumonia and admitted to a hospital. Materials and methods: The study enrolled 25 patients of 0-24 months referring to our hospital's pediatric clinic, who were then diagnosed with bronchopneumonia based on the World Health Organization diagnostic criteria and admitted to suckling children clinic due to inability to receive out-patient treatment, and 10 healthy children of the same age group, whose physical examinations revealed no pathological findings. Results: There was no difference between the groups in terms of age and gender distribution (p > 0.05). The control group included in the study showed a significantly higher mean duration of breast milk intake compared to the patient groups (p<0.001). WBC values obtained from the patient group was significantly higher than that of the control group (p<0.001). Zn and iron (Fe) values as determined in the control group enrolled in the study were significantly higher compared to the patient group (p<0.01). Mean total protein in the control group was found to be significantly higher versus that of the patient groups (p<0.05). With regard to the r values of correlation coefficients of the subjects enrolled in the study, a slightly positive correlation was observed between Zn levels and iron levels (r=0.457). Conclusion: It was concluded that infections, particularly pneumonia, which present a serious issue both in our country and developing countries, may be developed more commonly among children with zinc deficiency.
