    Bilateral mesial temporal sclerosis and kernicterus
    (LIPPINCOTT WILLIAMS & WILKINS, 2004) Paksoy, Y; Koc, H; Genc, BO
    Two children with mental retardation, choreoathetosis, dystonia, and muscle rigidity are reported. They had a history of severe hyperbilirubinemia after birth as a result of Rh iso immunization. The history and clinical picture suggested the diagnosis of kernicterus. The magnetic resonance imaging examination showed a bilateral signal intensity increase in the globus pallidus on T2-weighted images. Additionally, our patients showed symmetric bilateral hyperintensity and volume loss in the hippocampus, which is known to be another characteristic area of bilirubin deposition in kernicterus.

    Diminished platelet aggregation in patients with iron deficiency anemia
    (LIPPINCOTT WILLIAMS & WILKINS, 1999) Caliskan, U; Oner, AF; Kabakus, N; Koc, H
    To evaluate platelet function in iron deficiency anemia, using impedance (in whole blood) and optic tin platelet-rich plasma methods, platelet aggregation analyses were performed in 42 children with iron deficiency anemia at the time of diagnosis and after iron therapy. Collagen-induced platelet aggregation was decreased in patients before therapy compared to after therapy and control levels as indicated by the two methods while adenosine diphosphate (ADP)-induced platelet aggregation was decreased only by the whole blood method. Platelet aggregation with epinephrine, performed only by the optic method, was not altered in patients with iron deficiency anemia. Platelet counts were found to be increased in patients with iron deficiency anemia, and decreased with therapy. These results indicate that some platelet functions are decreased in patients with iron deficiency anemia. These decreased functions may be compensated by increased platelet numbers.

    Echocardiographic measurements in infants of diabetic mothers and macrosomic infants of nondiabetic mothers
    (WALTER DE GRUYTER & CO, 2005) Demiroren, K; Cam, L; Oran, B; Koc, H; Baspinar, O; Baysal, T; Karaaslan, S
    Aim: To compare echocardiographic findings of infants of diabetic mothers (IDMs), macrosomic infants of nondiabetic mothers and healthy full term appropriate-for-gestational-age (AGA) infants. Methods: Included in this study were 83 infants, admitted to our Neonatology Unit. Thirty-three IDMs, including both macrosomic and nonmacrosomic, comprised Group A, 25 macrosomic infants of nondiabetic mothers comprised group B, and 25 healthy full term AGA infants comprised group C. Echocardiographic measurements were performed in the first,three days after birth and compared by using one-way ANOVA, Post Hoc Tukey HSD and Student's t tests. Results: The left ventricular end-systolic/left ventricular end-diastolic diameter ratio of group A was significantly smaller than that of group C (P<0.05). The interventricular septum/posterior wall thickness ratios of groups A and B were greater than those of group C (P < 0.05). The left ventricular mass index of group A was greater than those of groups B and C (P < 0.05). The shortening fraction and ejection fraction of group A were increased in comparison to group C (P<0.05). When comparing the values of echocardiographic measurements of macrosomic IDMs (n = 9) with nonmacrosomic ones (n=24), and infants of pregestational diabetic mothers (n=11) with those of gestational diabetes mothers (n=22), no statistical difference was found. Conclusion: The present study suggests that underlying mechanisms common to both macrosomic infants of nondiabetic mothers and IDMs lead to less cardiac alterations in the macrosomic infants of nondiabetic mothers than in IDMs.
