Preoperative oAHI, preoperative oxygen desaturation index, pre- and postoperative OSA-18 scores correlated with OSA severity after adenotonsillectomy. However, in a multivariate model only the postoperative OSA-18 score correlated with OSA severity after adenotonsillectomy. Although adenotonsillectomy results in a significant improvement of OSA in children with trisomy 21, more than half of the children had persistent OSA. The postoperative OSA-18 score was associated both with persistent OSA and OSA severity after adenotonsillectomy.

We developed and validated a clinical prediction model for recovery from newly diagnosed ITP. The Childhood ITP Recovery Score predicts transient vs. persistent ITP and response to intravenous immunoglobulins. The score may serve as a useful tool for clinicians to individualize patient care. ABSTRACT Background Childhood immune thrombocytopenia (ITP) is an autoimmune bleeding disorder. The prognosis (transient, persistent, or chronic ITP) remains difficult to predict. The morbidity is most pronounced in children with persistent and chronic ITP. Clinical characteristics are associated with ITP outcomes, but there are no validated multivariate prediction models. Objective Development and external validatation of the Childhood ITP Recovery Score to predict transient versus persistent ITP in children with newly diagnosed ITP. Methods Patients with a diagnosis platelet count ≤ 20 × 109 /L and age belo
