RESUMO
Current recommendations advise against blood transfusion in hemodynamically stable children with iron deficiency anemia. In an observational study of 125 children aged 6 through 36 months, hospitalized with iron deficiency anemia, we found that hemoglobin level predicted red blood cell transfusion (area under the curve 0.8862). A hemoglobin of 39 g/L had sensitivity 92% and specificity 72% for transfusion.

Over the past 50 years, survival for children in high-income countries has increased from 30% to over 80%, compared to 10-30% in low and middle income countries (LMIC). Given this gap in survival, established paediatric cancer treatment centres, such as The Hospital for Sick Children (SickKids) are well positioned to share clinical expertise. Through the SickKids Centre for Global Child Health, the SickKids-Caribbean Initiative (SCI) was launched in March 2013 to improve the outcomes and quality of life for children with cancer and blood disorders in the Caribbean. The six participating Caribbean countries are among those defined by the United Nations as Small Island Developing States, due to their small size, remote location and limited accessibility. Telemedicine presents an opportunity to increase their accessibility to health care services and has been used by SCI to facilitate two series of interprofessional rounds. Case Consultation Review Rounds are a forum for learning about diagnostic work-up, management challenges and treatment recommendations for these diseases. To date, 54 cases have been reviewed by SickKids staff, of which 35 have been presented in monthly rounds. Patient Care Education Rounds provide nurses and other staff with the knowledge base needed to safely care for children and adolescents receiving treatment. Five of these rounds have taken place to date, with over 200 attendees. Utilized by SCI for both clinical and non-clinical meetings, telemedicine has enhanced opportunities for collaboration within the Caribbean region. By building capacity and nurturing expert knowledge through education, SCI hopes to contribute to closing the gap in childhood survival between high and low-resource settings.

OBJECTIVES: To determine alveolar and airways nitric oxide (NO) levels in children with sickle cell disease (SCD). STUDY DESIGN: Multiple flows fractional exhaled NO (FE(NO)), bronchial NO flux (J'aw(NO)), and alveolar NO concentration (Ca(NO)) were determined prospectively in 16 non-atopic children with SCD in a tertiary ambulatory clinic and compared with those in 10 children with primary ciliary dyskinesia and 22 healthy control subjects. Differences in FE(NO), J'aw(NO), and Ca(NO) were compared with mixed model analysis and Mann-Whitney tests. RESULTS: Children with SCD had reference range FE(NO) at 50 mL/sec, but FE(NO) was elevated across all flows compared with healthy control subjects (mean difference=2.10±0.91 parts per billion, P=.03). Subjects with SCD had increased J'aw(NO) (1177±533 picoliters per second versus 833±343 picolitres per second, P=.03), and Ca(NO) was no different from control subjects. In contrast, children with primary ciliary dyskinesia had decreased FE(NO) (mean difference=3.36±1.24 parts per billion, P<.01) and J'aw(NO) (507±259 picoliters per second versus 833±343 picoliters per second, P<.01). CONCLUSIONS: Lower airways NO is increased in children with SCD. Elevation of J'aw(NO) may represent dysregulation of NO metabolism or subclinical airways inflammation.
