Distribution of branchial anomalies in a paediatric Asian population

<p><b>INTRODUCTION</b>The objective of the present study was to review the distribution and incidence of branchial anomalies in an Asian paediatric population and highlight the challenges involved in the diagnosis of branchial anomalies.</p><p><b>METHODS</b>This was a retrospective chart review of all paediatric patients who underwent surgery for branchial anomalies in a tertiary paediatric hospital from August 2007 to November 2012. The clinical notes were correlated with preoperative radiological investigations, intraoperative findings and histology results. Branchial anomalies were classified based on the results of the review.</p><p><b>RESULTS</b>A total of 28 children underwent surgery for 30 branchial anomalies during the review period. Two children had bilateral branchial anomalies requiring excision. Of the 30 branchial anomalies, 7 (23.3%) were first branchial anomalies, 5 (16.7%) were second branchial anomalies, 3 (10.0%) were third branchial anomalies, and 4 (13.3%) were fourth branchial anomalies (one of the four patients with fourth branchial anomalies had bilateral branchial anomalies). In addition, seven children had 8 (26.7%) branchial anomalies that were thought to originate from the pyriform sinus; however, we were unable to determine if these anomalies were from the third or fourth branchial arches. There was inadequate information on the remaining 3 (10.0%) branchial anomalies for classification.</p><p><b>CONCLUSION</b>The incidence of second branchial anomalies appears to be lower in our Asian paediatric population, while that of third and fourth branchial anomalies was higher. Knowledge of embryology and the related anatomy of the branchial apparatus is crucial in the identification of the type of branchial anomaly.</p>

Recurrent Kawasaki disease presenting as acute airway obstruction

Kawasaki disease is a common paediatric vasculitide. It is usually diagnosed by its classical constellation of mucocutaneous signs. Recurrent Kawasaki disease is a rare phenomenon that occurs in approximately 3% of all patients diagnosed with Kawasaki disease. Its presentation is usually similar to the first episode of Kawasaki disease, and early diagnosis with prompt treatment is key in preventing associated cardiovascular morbidities. Recurrent Kawasaki disease is not well reported, and atypical presentations have not been previously reported in medical literature. Here, we report the case of a young girl with recurrent Kawasaki disease who presented atypically with acute airway obstruction secondary to retropharyngeal phlegmon.
