    ABSTRACT: Hypoxic-ischemic cerebral injury due to perinatal asphyxia is an important cause of neonatal mortality and morbidity. To predict who will survive or die due to this disorder still remains obscure. The aim of this study is to evaluate the predictive value of myocardial involvement in the assessment of mortality for the neonates with hypoxic-ischemic encephalopathy (HIE). The study included 34 term newborns fulfilling the diagnostic criteria for HIE and staged according to Sarnat and Sarnat classification. To assess the myocardial involvement, electrocardiogram (ECG) and echocardiogram (Echo) were performed in the first 24-48 h of life. In addition, serum Troponin I and creatine kinase-myocardial band (CK-MB) were measured at delivery and postnatal day 3. Of the 34 cases, 19 (55.9%) were stage in 1, 9 were in (26.4%) stage 2 and 6 (17.6%) were in stage 3 HIE. Nine (26.4%) patients died of the disease. Thirteen patients (38.2%) showed ECG findings related to perinatal asphyxia. Only one patient had mild Echo changes. Higher Troponin I level was a significant predictor of mortality, whereas CK-MB did not show any significant predicting value. Troponin I test showed 33% sensitivity and 80% specificity in predicting mortality. In addition, the sensitivity and specificity of ECG as a predictor of mortality were 77 and 76%, respectively. This study highlights the significance of monitoring cardiac functions in newborns with HIE. ECG changes and serum Troponin I level at 72 h after birth are likely to have significant predictive value in the assessment of mortality in HIE. Further studies will provide additional data for the long-term prognostic value of cardiac functions in this disorder.

    ABSTRACT: Large pericardial effusions and cardiac tamponade are rare in childhood. The aim of this study was to evaluate the aetiological factors and clinical findings of large pericardial effusion and cardiac tamponade in children. We reviewed retrospectively the records of 10 (6 male, 4 female) patients (mean age: 8.05 +/- 4.4 y) with the diagnosis of large pericardial effusion and cardiac tamponade requiring pericardiocentesis and pericardial drainage between 2002 and 2004. After extensive diagnostic investigation we detected that three patients had tuberculosis, one patient had uraemic pericarditis; one patient had bacterial pericarditis; one patient had post-pericardiotomy syndrome; two patients had malignancy and two patients had no identifiable aetiology. Echocardiography-guided percutaneous pericardial puncture and pigtail catheter placement is safe and effective for initial treatment of patients with large pericardial effusion and cardiac tamponade and in most cases, initial assessment with clinical, serologic, and radiologic investigation and careful follow-up can reveal the aetiology. Although tuberculosis is rare in industrialized countries, in developing countries it remains one of the most important causes of large pericardial effusion and should be investigated and excluded in each patient.
