Bone marrow necrosis (BMN) is a rare pathologic finding, but when encountered is most often associated with malignancy. In adults, its presence correlates with an inferior prognosis, however in children the prognostic implication is unclear. We performed a retrospective review of 3,760 bone marrow specimens in patients ≤18 years over a 10-year period. BMN was identified in less than 1% of specimens and only in patients with leukemia, lymphoma, or neuroblastoma. BMN contributed to a delay in diagnosis; however, advanced medical imaging may serve as a tool to localize nonnecrotic areas for bone marrow sampling, facilitating an expedited diagnosis.

Forty-one residents enrolled and 32 (78%) completed a post-programme survey. Of those, 21 (66%) preferred a Q&A format with an immediate text response versus information-only texts. The percentage change in ITE scores between 2013 and 2014 was significant. Comparing subgroups, there was no significant difference between the percentage change in ITE scores. Neither group performed significantly better on either the adolescent or developmental sections of the ITE. Text messaging… remains an underused educational tool CONCLUSIONS: Overall, participants improved their ITE scores, but no improvement was seen in the targeted subgroups on the exam. Although Q&A texts are preferred by residents, further assessment is required to assess the effect on educational outcomes.
