Procalcitonin (PCT) and C-reactive protein (CRP) are two acute-phase reactants with different clinical features. The study aimed to compare the diagnostic value of admission serum PCT and CRP concentrations as indicators of aetiology and intensity of inflammation in children hospitalized with diarrhoea. ⋯ In this study PCT was a more reliable marker than CRP of systemic bacterial infection in children with diarrhoea. PCT was more specific but less sensitive in the differentiation of bacterial and non-bacterial aetiology of inflammation.

To study the aetiology and clinical course of children with brainstem death in a paediatric intensive care unit (ICU) and to determine whether current the practices that are used to declare brainstem death conform to accepted criteria. ⋯ Trauma remains the most common primary diagnosis leading to brainstem death. Intensivists in this large hospital for children mainly conform to accepted guidelines for determination of brainstem death although there is a wider use of ancillary tests to aid diagnosis. The study also showed a low rate of < 10% of organ procurement for transplantation.

To determine cerebral blood flow using near infrared spectroscopy in extremely preterm infants undergoing high-frequency oscillatory ventilation during the first three days of life. Low cerebral blood flow has been associated with both intra-ventricular haemorrhage and periventricular leucomalacia. It is well established that cerebral blood flow increases over the first three days of life in extremely preterm infants who are conventionally ventilated with intermittent positive pressure ventilation. However, there is no information about cerebral blood flow in preterm babies undergoing high-frequency oscillatory ventilation. In addition, there are concerns that high-frequency oscillatory ventilation may be associated with an increased incidence of intra-ventricular haemorrhage in premature infants. ⋯ Cerebral blood flow is extremely low in this group of preterm babies. Despite this extremely low cerebral blood flow, the clinical outcome is good. There was an increase in cerebral blood flow and a corresponding increase in left ventricular output over the first few days of life.

Supraventricular tachycardia: an incidental diagnosis in infants and difficult to prove in children.
To determine (a) the age distribution at first clinical supraventricular tachycardia (SVT) presentation; (b) the time interval between first clinical suspicion and electrocardiographic proof of SVT; c) the most indicative symptoms and signs of SVT; and (d) the SVT mechanism and its age distribution according to surface ECG. ⋯ In infants SVT is a chance finding; SVT can only be proven electrocardiographically with a median delay of 138 d, despite the presence of symptoms; SVT using a (concealed) accessory pathway is the most common mechanism.

Epilepsy is a common paroxysmal disorder in childhood. Tachyarrhythmia, bradyarrhythmia, asystole, atrioventricular block, ventricular fibrillation or sudden death may occur during seizures. Mutations of ion-channel coding genes are found in patients with idiopathic or cryptogenic epilepsy. The ion channels also play a role in arrhythmogenesis. QT dispersion is a non-invasive method for assessment of regional repolarization differences within the myocardial tissue. This study investigated QT and QTc dispersion (QTcd) and the risk of dysrhythmia in epileptic children. ⋯ QT dispersion is increased in epileptic children. Further investigation is needed to reveal the pathogenesis of myocardial repolarization abnormalities in epileptic patients.
