Molecular characterization of long-term survivors of metastatic medulloblastoma treated with reduced-dose craniospinal irradiation.

Background And Aims: Current standard treatment for metastatic medulloblastoma consists of 36 Gray (Gy) of craniospinal irradiation (CSI) supplemented with local irradiation and adjuvant chemotherapy after surgery. Although contemporary protocols have been designed to limit a radiation dose using risk-adapted CSI dosing to reduce neurocognitive morbidity, high-dose CSI remains the standard of care. Recently, the molecular classification of medulloblastoma has been emerging but its clinical significance has not been established particularly in patients with metastatic medulloblastoma treated with lower dose of CSI.

Long-term efficacy and safety profile of splenectomy for pediatric chronic immune thrombocytopenia.

There are few reports of the long-term efficacy of splenectomy in children with immune thrombocytopenia (ITP). In a 33-year period, we performed splenectomies in 23 pediatric patients with ITP at a single institution in Japan. The age at surgery was 5-22 years with a median of 10 years.

Successful perioperative management using prothrombin complex concentrates in patients with severe congenital protein C deficiency.

Perioperative management of severe congenital protein C deficiency remains unestablished. This deficiency is often treated with anticoagulants, such as warfarin. Although anticoagulants need to be perioperatively discontinued, there are few methods for the management of such patients.
