RESUMEN
BACKGROUND: The published incidence of paracetamol cross-reactivity in adults and adolescents with nonsteroidal anti-inflammatory drug (NSAID) reactions is low and all data on such reactions in young children is sparse. The study aim was to characterize the clinical presentation and cross-reactivity with paracetamol in patients with a reported onset of NSAID hypersensitivity before 6 years of age. METHODS: A retrospective case review was done of patients with cross-reactive hypersensitivity reactions to antipyretic/analgesic medications from the pediatric allergy clinic of the Kendang Kerbau Hospital, Singapore. Included patients reported the onset of such reactions before 6 years of age. Hypersensitivity was established through a detailed history of recurrent reactions to NSAIDs or an oral provocation test. RESULTS: Eighteen patients fulfilled the diagnostic criteria within the study period. Eighty-three percent had cross-reactive reactions with paracetamol. When compared to the group of children with later onset of NSAID hypersensitivity, children with onset before 6 years of age had a significantly increased likelihood of reacting to paracetamol (odds ratio 9.6, 95% confidence interval 1.6-58.0, p < 0.05). CONCLUSION: Paracetamol seems to be a major eliciting drug in this group of children.

INTRODUCTION: This study aimed to determine compliance with noninvasive home ventilation in children with obstructive sleep apnoea and the factors affecting this compliance. METHODS: We retrospectively reviewed 51 children who were prescribed noninvasive home ventilation for the management of obstructive sleep apnoea from 1 January 2000 until 31 May 2008. Noninvasive ventilation was started based on positive polysomnogram, i.e. obstructive apnoea hypopnea index ≥ 1/hr. Compliance was defined as the use of noninvasive ventilation ≥ 4 days/week. RESULTS: Noninvasive home ventilation was started at a median age of 11.5 years. In all, 21 (41.2 %) children were reported to be compliant with treatment. Univariate analysis revealed that the female gender (p = 0.017), presence of asthma (p = 0.023), presence of genetic syndromes (p = 0.023), use of bi-level ventilation versus continuous positive airway pressure (p = 0.027), and funding from the social work department (p = 0.049) were associated with compliance with noninvasive home ventilation. Logistic regression revealed the presence of asthma (p = 0.008) and female gender (p = 0.047) to be significantly associated with compliance with treatment. However, factors such as counselling prior to initiation of treatment, severity of obstructive sleep apnoea before initiation of treatment, obesity, use of humidification, and polysomnogram indices were not found to be associated with treatment compliance. CONCLUSION: Only 41.2% of the children in this study were reported to be compliant with noninvasive home ventilation. The female gender and the presence of asthma were associated with treatment compliance. Future research focusing on effective methods to improve compliance with noninvasive home ventilation in children should be undertaken.

OBJECTIVE: To compare the effectiveness of the administration of inhaled beta-agonists delivered via a metered-dose inhaler (MDI) with spacers--as part of an evidence-based asthma pathway developed to manage acute asthma exacerbations in children at the emergency room level and in inpatient management--against administration via nebulization. DESIGN: Case with historical control. SETTING: KK Women's and Children's Hospital (Singapore). PARTICIPANTS: A total of 19,951 children (infants to older children) aged 18 years and younger who attended the emergency room for asthma exacerbations. MAIN OUTCOME MEASURES: Average length of stay, proportion admitted to high dependency or intensive care, proportion readmitted for unresolved symptoms within 72 hr, cost per patient and overall. RESULTS: There was no increase in the mean proportion of emergency room attendances admitted to inpatient care with use of an MDI (mean difference 0.97%, 95% CI: -1.6-3.5%, P = 0.447), nor of children admitted to intensive care (0.21 vs. 0.20 pre- and post-pathway, P = 0.827) or to high dependency units (2.21 vs. 1.37 pre- and post-pathway, P = 0.200) but a significant reduction in the within 72 hr re-attendance rate (mean difference 1.4%, 95% CI: 0.78-2.0%, P < 0.001) with use of an MDI. The average length and cost per patient for an inpatient stay for acute asthma exacerbations was reduced with use of an MDI. CONCLUSIONS: The use of an MDI with spacer as part of an evidence-based asthma pathway was effective in the management of acute asthma exacerbations in the emergency room setting and for inpatient management.
