Increased Prevalence of Clostridioides difficile Infection Among Pediatric Oncology Patients: Risk Factors for Infection and Complications.

Background: Pediatric oncology patients, who are typically immunosuppressed, exposed to medications associated with increased Clostridioides difficile infection (CDI) risk and hospitalized, are expected to be at substantial risk for infection and complications. Although certain C. difficile ribotypes have been associated with more severe infection in adults, such an association has not been described in children.

High Rates of Obesity at Presentation Persist into Survivorship across Childhood Cancer Types.

Subtypes of pediatric oncology patients and childhood cancer survivors who are overweight or obese have worse prognosis than their healthy-weighted peers. Several studies have examined weight status in either pediatric patients or survivors with acute leukemia, but few have compared these data across various diagnoses. We examined BMI from oncology diagnosis or presentation, through treatment, and into survivorship across the most common cancer types seen in pediatric oncology.

Development of acute lymphoblastic leukemia following treatment for acute myeloid leukemia in children with Down syndrome: A case report and retrospective review of Children's Oncology Group acute myeloid leukemia trials.

Children with Down syndrome have a 150-fold increased risk of developing acute myeloid leukemia (AML) and 20-fold increased risk of developing acute lymphoblastic leukemia (ALL). Although the risk of developing AML and ALL is significantly increased in children with Down syndrome, the development of both malignancies in the same patient is very rare. We describe a patient with Down syndrome who developed ALL 6 years after being diagnosed with AML.
