Comparative StudySimilar survival following HLA-identical sibling transplantation for standard indication in children with haematologic malignancies: a single center comparison of mobilized peripheral blood stem cell with bone marrow transplantation.
Peripheral blood stem cell (PBSC) grafts are increasingly used for autologous and allogeneic haematopoietic stem cell transplantation (alloHSCT) with the aim to hasten neutrophil and platelet engraftment and thereby to reduce transplant-related complications due to infections, bleeding and graft failure. Based on the paucity of data on PBSC transplantation in children we performed a retrospective single-center analysis comparing the outcome of children receiving mobilized PBSC from human leukocyte antigen (HLA)-identical sibling donors to bone marrow (BM) transplant recipients. ⋯ Transplantation of PBSC compared to BM is associated with faster neutrophil engraftment and a higher rate of > or = grade II acute GvHD. As overall survival and event-free survival is similar when using PBSC and BM, PBSC is an alternative stem cell source for HLA-identical sibling transplantation. Further prospective analyses with higher number of patients stratified according to well established risk factors are required to define the precise role of both stem cell sources for children with haematologic malignancies.

Case ReportsSevere valproic acid intoxication is associated with atrial tachycardia: secondary detoxication by hemoperfusion.
Valproic acid is an anticonvulsant drug which is associated with serious toxicity including fatal outcome in case of severe intoxication. Secondary detoxication by hemodialysis or hemoperfusion has been employed successfully in valproic acid intoxication. Cardiac arrhythmias have only been described rarely in valproic acid intoxication in humans. ⋯ The patient was successfully treated with hemoperfusion and intensive supportive care without implementation of a specific antiarrhythmic therapy. We conclude that patients with severe valproic acid intoxication may benefit from secondary detoxication. In addition to generally known symptoms valproic acid intoxication may also be associated with cardiac arrhythmias.

[Are there predictors for proliferative retinopathy of prematurity and is supplemental oxygen a useful conservative treatment option?].
Especially very immature preterm babies develop retinopathy of prematurity (ROP). This study aims at analysing risk factors for proliferative ROP and realizing the efficiency of supplemental oxygen therapy. ⋯ Especially measures against long duration of intubation could help to prevent high grade ROP. The supplemental oxygen therapy may have a positive effect on course.

Comparative StudyBone marrow oedema and aseptic osteonecrosis in children and adolescents with acute lymphoblastic leukaemia or non-Hodgkin-lymphoma treated with hyperbaric-oxygen-therapy (HBO): an approach to cure? -- BME/AON and hyperbaric oxygen therapy as a treatment modality.
There is a striking need for additional therapies of bone marrow oedema (BME) and aseptic osteonecrosis (AON) in paediatric oncology patients. Hyperbaric oxygenation (HBO) therapy used in the treatment of osteoradionecrosis is demonstrated effectiveness. Aim of this retrospective analysis was to investigate whether HBO-therapy might lead to subjective as well as objective effects in the treatment of BME and/or AON in paediatric oncology patients with acute lymphoblastic leukaemia (ALL) or Non-Hodgkin lymphoma (NHL). ⋯ Children and adolescents diagnosed with ALL or NHL have a risk for accruement of BME and/or AON irrespective of the age, with an almost exclusive involvement of the lower extremities. Lesions of pedal bones and ankle joints predominantly affect children < 10 years. Lesions of knee and hip joints predominantly affect children > 10 years. In children < 10 years of age we demonstrate declining AON numbers and conversion of AON to BME thereby implicating possible beneficial effect of HBO in such patients. HBO failed to show beneficial effect on BME whether by preventing new lesions or by improving existent lesions in children > 10 years.

Multicenter Study Comparative Study Clinical TrialLow grade chiasmatic-hypothalamic glioma-carboplatin and vincristin chemotherapy effectively defers radiotherapy within a comprehensive treatment strategy -- report from the multicenter treatment study for children and adolescents with a low grade glioma -- HIT-LGG 1996 -- of the Society of Pediatric Oncology and Hematology (GPOH).
Low grade gliomas arise in all CNS-locations and age groups, chiasmatic-hypothalamic tumors occur especially in young children. Early radiotherapy (RT) shall be deferred by chemotherapy (CT) within the concept of the HIT-LGG 1996 study, offering a comprehensive treatment strategy for all age groups. ⋯ Within the comprehensive treatment strategy for low grade glioma HIT-LGG 1996 chemotherapy is effective to delay the need for early radiotherapy in chiasmatic-hypothalamic glioma. More effective reduction of the risk for progression has to be sought for young children < 1 year.
