CPOE implementation decreased prescription errors only to a small extent. However, the addition of a CDSS that limits doses by weight significantly reduced prescription error rates and, most importantly, potential ADEs. This finding emphasizes the major impact of weight-based calculation errors in pediatrics.

Zygomycetes infection is associated with a high mortality in transplant populations. We describe a child with liver allograft Rhizopus oryzae infection who was salvaged by liver re-transplantation. A 10-year-old child presented with anastomotic bile leak that was repaired. A combined antibiotics and voriconazole regimen was introduced for Escherichia coli and Candida krusei growth in the peritoneal fluid. Despite broad antibiotic and antifungal coverage, the patient continued to have an ongoing infection. A follow-up computed tomography scan 8 weeks later showed 2 liver abscesses infiltrating the stomach and the diaphragm, with splenic infarcts and pericardial effusion. Aspirated samples from the liver abscess and the pericardial fluid revealed R. oryzae. Immunosuppression was discontinued and an antifungal regimen combining amphotericin B, posaconazole, and caspofungin was introduced. After 3 weeks of treatment with control of the systemic signs of infection, a positron emission tomography showed the fluorescence stain limited to the liver. With infection confined to the liver, the child underwent liver re-transplantation, splenectomy, and partial gastrectomy. Immunosuppression was reintroduced with recovery of the immune response observed by the CD4 cells adenosine triphophate release (Cylex(™) ImmuKnow(®) assay) and posaconazole was continued for another year. At 3-year follow-up, the child maintained normal graft function. We conclude that discontinuation of immunosuppression combined with a modern antifungal regimen may allow salvage re-transplantation in patients with liver mucormycosis.

Background High‐flow nasal cannula (HFNC) therapy may be better tolerated than traditional noninvasive ventilation (NIV) and is rapidly gaining acceptance in pediatric acute care. In Israel, HFNC is approved for domestic use. We aim to describe its indications, efficacy, parental satisfaction, and safety. Methods Retrospective study of children treated with home HFNC therapy in three pediatric centers. Data included demographic parameters, indication of use, weight and days of hospitalization before and after initiation. Safety, tolerability, and parental satisfaction were assessed via standardized telephone questionnaire. Results Median (interquartile range [IQR]) age of initiating home HFNC in 75 children was 8.3 (2.2, 29.6) months. Indications were obstructive sleep apnea (33; 44%), airway malacia (19; 25%), chronic lung disease (15; 20%), neuromuscular disease (4; 5%), and postextubation support (4; 5%). Weight standard deviation score rose from −2.3 pre‐HFNC to −1.7 at 6.7 months post‐HFNC initiation, p < 0.001. Hospital admission days during the 2 months pre‐ versus post‐HFNC initiation were 22 (5.5, 60) and 5 (0, 14.7) respectively, p < 0.008. Median (IQR) parental satisfaction score was 5/5 (4, 5). Fifty of 60 (83%) respondents would recommend home HFNC to other families in a similar situation. There were no serious adverse events. Conclusion In our population, domestic HFNC appeared safe and well tolerated for a variety of indications. Its introduction was associated with improved weight gain, fewer hospitalization days and high parental satisfaction. Further work is required to characterize groups of children most likely to benefit from HFNC, as opposed to traditional modes of NIV.
