Background: High-dose chemotherapy with autologous stem cell rescue (HDC/SCR) has produced responses and prolonged survival for some children with recurrent brain tumors, but is associated with considerable morbidity and mortality. A Phase I trial of two cycles of HDC/SCR for recurrent brain tumors in children was performed to determine the maximum tolerated doses for a novel regimen.
Procedures: Two cycles of HDC/SCR were given.
Limited information is available regarding the use of amifostine in pediatric hematopoietic stem cell transplant (HSCT) patients. Melphalan, carboplatin, etoposide +/- cyclophosphamide is a commonly used preparatory regimen in pediatric solid tumor HSCT. Therefore, we decided to determine the feasibility of the addition of amifostine (750 mg/m b.

- Rhabdomyosarcoma (RMS) is a rare but significant eye tumor that poses diagnostic and management challenges for ocular oncologists, often appearing in the first decade of life.
- Commonly found in the superior nasal quadrant of the orbit, RMS can mimic other lesions, with its effects varying based on tumor location and growth rate.
- Advances in chemotherapy and radiotherapy have improved survival rates, but posttreatment complications like secondary malignancies and visual dysfunction present new challenges for long-term care.
Bacillus cereus central line infection in an immunocompetent child with hemophilia.
J Pediatr Hematol Oncol
March 2004
Bacillus species are increasingly recognized as pathogens in immunocompromised patients. The authors report a case of Bacillus cereus infection of a central line in an immunocompetent patient with hemophilia, which required line removal for complete cure.

Their ability to respond to unrelated microenvironmental signals strongly suggest that they have greater potential than previously imagined especially for their future clinical use for the regeneration of tissues or even perhaps organ systems. In particular there is an intriguing reciprocal relationship between the hematopoietic and neuronal stem cell systems.
