Abstract Background Transient hyperglycemia (TH) is a recognized side effect of the corticosteroids and asparaginase given during induction chemotherapy for pediatric acute lymphoblastic leukemia (ALL). Information needed about how TH has been impacted by changes in ALL therapy. This study examined prevalence cohort patients impact on type steroid or used risk factors such as age, gender, overweight. Methods Retrospective record review aged 2–18 years diagnosed with 1999–2006. was defined ≥2...

Event-free survival for recurrent alveolar rhabdomyosarcoma (ARMS) is poor, and a consensus approach to treatment in the relapse setting has not been established. Recent studies suggest that combination regimen of vincristine, irinotecan, temozolomide (VITA) active against sarcomas. We present our single-institution experience with this relapsed ARMS heavily pretreated patients, including those prior exposure vincristine irinotecan. observed complete radiographic response 1 4 patients who...

Abstract Late hemorrhagic disease of the newborn (HDN) presents 0.5–6 months after birth with mucocutaneous and intracranial bleeding. We describe here two cases late HDN in infants who received vitamin K. The first case is a previously healthy breastfed male one dose oral K at developed an hemorrhage 5 weeks later. He was treated intravenous recombinant factor VIIa prior to emergent craniectomy. An unrelated infant presented age diarrhea easy bruising despite IM birth. These illustrate...

The incidence of bacteremia at the onset pediatric febrile neutropenia (FN) 2 academically linked institutions was 9.84%, and subsequent blood cultures performed for children with persistent FN yielded an 4.21%. Until risk factors new-onset in patients being treated can be identified diagnostic methods improved, compliance national guidelines is recommended.

Abstract Background Pediatric acute lymphoblastic leukemia (ALL) therapies have been associated with many late effects, including obesity, hyperglycemia, and insulin resistance. Few data are available linking these abnormalities to specific risk factors present during ALL treatment. Methods Retrospective cohort study prospective follow‐up. Subjects had diagnosed at ages 1–18 years off chemotherapy for >9 months. Oral glucose tolerance testing (OGTT) was performed results compared...

We report a case of 2-year-old girl who was diagnosed with natural killer cell acute lymphoblastic leukemia and treated an chemotherapy regimen. Two months posttherapy, the disease relapsed myeloid immunophenotype. Complete response then achieved therapy followed by unrelated donor umbilical cord allogenic stem transplant. Retrospectively, reanalysis diagnostic specimen showed minimal myeloperoxidase expression that called negative conventional single parameter linear gating but better...
