Résumé

Abstract The effect of hypothermia treatment on white blood cell (WBC), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR) and platelet-to-lymphocyte ratio (PLR) values as an indicator of inflammation was evaluated in newborns with hypoxic ischemic encephalopathy (HIE). The study was performed that the before-therapeutic hypothermia (TH) and after-TH WBC, lymphocytes, neutrophils, monocytes and NLR, LMR and PLR values of the complete blood cell count were retrospectively evaluated. The results of the patient group were compared with the results of healthy newborns. A total of 78 patients who underwent TH were evaluated in our study. Mean values before and after TH were NLR3.8/2.7, LMR 5.6/8.6, and PLR 60.3/67.1 respectively. A statistical significance was present for NLR values before and after TH in those with seizure in our study (4.15±2.95/3.01±2.54) but no statistical significance was found for LMR or PLR. In neonates with HIE, effect of TH on complete blood cell count and inflammatory mechanisms (mediated neutrophil and lymphocyte) may be minimal.

Résumé

Functional imaging studies in patients with Sydenhams chorea have suggested brain perfusional abnormalities. In this study, we aimed to investigate the cerebral perfusion patterns of the cortical/subcortical structures by using Tc-99m hexamethylpropylenamine oxime single photon emission computed tomography in children with Sydenhams chorea, accompanied with magnetic resonance imaging and cranial Doppler studies. Brain MRI and Doppler studies of the all cases were normal. In the brain SPECT study, six patients were determined to have cerebral perfusion abnormalities. Although six patients responded well to the therapy, two girls who had hypoperfusion in the right frontal region as well as hypo- / hyperperfusion in the basal ganglia did not respond to therapy. While the chorea form of the patients who have cerebral perfusional abnormality was generalized, the clinical picture of the patients with normal cerebral perfusion was in the form of hemichorea.
