The validity of the OSA-18 among three groups of pediatric patients

Adenotonsillar enlargement in pediatric transplant recipients can be an early indication of post-transplantation lymphoproliferative disorder. However, the prevalence of adenotonsillar enlargement in the transplant population does not appear to differ from that of the healthy population. Additionally, scores on the OSA-18 in the transplant population were confounded by chronic illness. Further prospective studies need to be performed to develop a screening tool to identify transplant recipients at risk for post-transplantation adenotonsillar lymphoma.
