The Italian version of the PedsQL in children with rheumatic diseases.

OBJECTIVE: The aim of the study was to test the reliability and validity of the Italian translation of the PedsQL 4.0 Generic Core Scales and the PedsQL 3.0 Rheumatologic Module in a sample of rheumatologic children in Italy. METHODS: The PedsQL 4.0 and the PedsQL 3.0 were administered to rheumatic and healthy children. 102 children 5-18 years old and 132 parents of children 2-18 years old were tested. Additionally, the Child Health Questionnaire - Parent Form 50 - was administered to the rheumatologic sample. RESULTS: Internal consistency reliability for group comparisons reached the recommended coefficient alpha of 0.70 for PedsQL 4.0 and PedsQL 3.0. The inter-correlation between these last ones was highly significant. The correlation between the PedsQL 4.0 and the CHQ was statistically significant. CONCLUSION: The Italian version of the PedsQL 4.0 and PedsQL 3.0 Rheumatology Module demonstrate acceptable reliability and validity for both patient self-report and parent proxy-report.

Behavioural and physiological reactivity to noise in the newborn.

OBJECTIVE: To assess the electromyographic (EMG) and behavioural reactivity of a group of newborn infants exposed to noisy stimulation of various intensity recorded in the Paediatric intensive care Unit (PICU). METHODS: The study was performed at the nursery of the Paediatrics Department (University of Padova) on a group of 21 healthy newborns (mean 39 weeks of gestation), assessed between 24 and 72 h after birth. The study involved taking EMG recordings of the corrugator supercilii muscle and assessing the infant's behaviour at the baseline (15 seconds before stimulation), during noisy stimulation (for 1-2 seconds) and during recovery (15 seconds in three subphases). The noises, previously recorded in PICU, had four different intensities and were administered in random order to all infants. Descriptive analysis and repeated-measures analysis of variance (anova) were performed on the EMG and behavioural data. RESULTS: The infants demonstrated a significant reaction to the noises both in the EMG recordings and in behavioural changes, especially during intense noisy stimulation. The reaction lasted longer than the stimulation period, preventing the infants from returning to the baseline condition. CONCLUSIONS: Exposure to high-intensity noise produced in PICU causes evident behavioural and physiological effects (EMG). This is a field of study that could have important repercussions, given the medium- and long-term effects of repeated noise stimulation.

[Assessment and measurement of pain in infants and children]. / Valutazione e msiurazione del dolore in età pediatrica.

The assessment of global pain in infants and children involves the analysis of subjective, behavioural and physiological components, beyond the psychological, familiar and environmental factors that influence and modulate the manifestation of painful symptom. Therefore, researchers and clinicians need valid and reliable instruments to obtain a correct measure of pain. Although subjective indices carry out a fundamental role in the assessment of pain (instruments adjusted to the age of the child), behavioural and physiological indices should be used when intelligence deficit or serious physical handicaps exclude such possibility. Behavioural aspects, associated and correlated to physiological changes, allow to obtain a reliable enough measure of pain. In this paper, the main instruments for measuring pain in infants and children will be described, and their advantages and disadvantages underlined.
