In certain patients, such as young children or individuals with cerebral palsy or severe mental retardation, it is difficult to perform forced expiratory manoeuvres to measure expiratory flow volume. In such cases, we could evaluate obstructive lung disease through the measurement of airway resistance instead of expiratory flow volume. ⋯ FEV(1), FVC and PEFR were significantly correlated with IOS parameters, in both asthmatic and control subjects, especially for atopic children. IOS could be used as a suitable measure of lung function when spirometry and PEF cannot be performed.

The amplitude-integrated electroencephalogram (aEEG) is a useful tool to assess brain function after perinatal asphyxia in term infants. We report a full-term newborn with moderate perinatal asphyxia, who accidentally received an overdose of morphine (5000 microg/kg). The overdose of morphine resulted in a clear and immediate change of aEEG background activity from a continuous (C) to discontinuous (DC) background pattern. After administration of naloxone, the background activity restored immediately to continuous background pattern. The aEEG was used to monitor the stepwise reduction in continuous naloxone infusion. ⋯ An overdose of morphine leads to clear and immediate changes in aEEG which restore after naloxone treatment. The aEEG can be used to monitor naloxone infusion.

Comparative Study
Assessment of the prevalence of microaspiration by gastric pepsin in the airway of ventilated children.
Mechanically ventilated patients are at risk for aspiration of gastric contents. The aim of this observational study was to determine the prevalence of micro-aspiration in children with cuffed and uncuffed endotracheal (ET) tubes and with tracheostomies and to assess the effect of feeding status on aspiration. Micro-aspiration was determined by measuring gastric pepsin in tracheal aspirates. ⋯ Measurement of gastric pepsin in tracheobronchial fluid is a sensitive tool to detect aspirations in mechanically ventilated children and to assess the efficacy of preventive measures in PICU settings.

The proportion of Scandinavian school children reporting psychosomatic pain and psychological complaints have increased in recent decades. In this study we investigated these symptoms in relation to potential stressors in the school environment. ⋯ School stressors are strongly associated with psychosomatic pain and psychological complaints in school children. Psychological complaints seem to function as mediators in the association of school stressors to psychosomatic pain symptoms to a great extent.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare arrythmogenic disease characterized by exercise--or stress--induced ventricular tachyarrythmias, syncope, or sudden death, usually in the pediatric age group. Familial occurrence has been noted in about 30% of cases. Inheritance may be autosomal dominant or recessive, usually with high penetrance. The causative genes have been mapped to chromosome 1. Mutations of the cardiac ryanodine receptor gene (RyR2) have been identified in autosomal dominant pedigrees, while calsequestrin gene (CASQ2) mutations are seen in recessive cases. ⋯ Due to its potential lethal outcome, exclusion or confirmation of catecholaminergic polymorphic ventricular tachycardia in children with physical and emotional syncope is mandatory. We report a case of catecholaminergic polymorphic ventricular tachycardia in a three-year-old child only diagnosed by genetic mapping.
