Massive Transfusion in Pediatric Patients on Extracorporeal Membrane Oxygenation: A Secondary Analysis of the Massive Transfusion in Children (MATIC) Study.

Few data describe pediatric patients who receive massive transfusion for life-threatening hemorrhage (LTH) while on extracorporeal membrane oxygenation (ECMO). We present a retrospective secondary analysis of a multicenter prospective observational study to describe resource utilization and mortality in pediatric patients with LTH while on ECMO. Children who were on ECMO during an LTH were compared to children with LTH who were not on ECMO. Primary outcomes were volumes of blood products administered and 28 day mortality. Comparisons were assessed by two-sided Fisher's exact test or Wilcoxon rank sum test. A total of 449 children, including 36 on ECMO, were included. Compared to those not on ECMO, children on ECMO received a higher volume of blood products (110 [50-223] vs. 59 [28-113]) ml/kg, p = 0.002) and were more likely to receive antifibrinolytic therapy (39% vs. 10%, p < 0.001). Blood product ratios were similar. Extracorporeal membrane oxygenation patients had higher 28 day mortality (64% vs. 35%, p = 0.001), although 24 hour mortality was similar (17% vs. 23%, p = 0.5). In conclusion, children on ECMO with LTH experience high resource utilization and 28 day mortality. Studies are needed to identify children at risk for LTH and to evaluate ECMO-specific treatment strategies.

Mucinous adenocarcinoma of the endometrium with metastasis to the clitoral glans after pelvic exenteration for radiation resistant vaginal cuff recurrence.

Mucinous adenocarcinoma of the endometrium (MACE) is a rare subtype of endometrial adenocarcinoma that often presents a significant diagnostic challenge due to its variation from the conventional morphologic appearance of endometrioid epithelium. This case report is of a woman who has survived 4 years after pelvic exenteration and subsequent vulvectomy for recurrent MACE.
