Megachemotherapy followed by autologous stem cell transplantation in children with Ewing's sarcoma.
Twenty-one children with high-risk Ewing's tumor received high-dose chemotherapy with a PBSCT. Aim of the study was evaluation of efficiency and safety of this procedure. All but three patients have meta-static disease at presentation. ⋯ Autologos transplantation in children with metastatic Ewing's sarcoma seems to improve their outcome. Patients with Ewing's sarcoma, resistant to conventional therapy and with recurrent disease did not benefit from megachemotherapy. New approaches such as anti-tumor vaccination or using of imatinib are reasonable to introduce in patients with relapsed or resistant to therapy Ewing's tumor.

Sirolimus represents a major advancement in the field of solid organ transplantation and is being used as a rescue agent for acute and chronic rejection as well as for primary immunosuppression with good graft outcome. Although initial studies with sirolimus were in adults, now significant data have accumulated on the role of sirolimus in pediatric solid organ transplantation. This article reviews the current status of sirolimus in pediatric transplantation.

Comparative StudyTransfusion requirements during cadaveric and living donor pediatric liver transplantation.
Surgical techniques that have been used during liver transplantation (LT) together with patient's coagulation profile and institutional practices are reported to have an effect on transfusion requirements. The aim of this study is to evaluate the transfusion requirement in both cadaveric (CDLT, n = 22) and living donor (LDLT, n = 24) pediatric LT performed in our institution. Balanced general anesthesia was used for all patients. ⋯ As a result of this study in a pediatric patient population, no statistical significance was found in whole blood transfusion and FFP requirements between CDLT and LDLT. Duration of the operation was the primary factor effecting transfusion volume showing the importance of continued small volume losses during uncomplicated LT in this small sized patient population. Transfusion need for pediatric LT should be individualized for each patient based on the intraoperative conditions including surgical and patient features.

Case ReportsDevelopment of hepatopulmonary syndrome and portopulmonary hypertension in a paediatric liver transplant patient.
Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PPH) are pulmonary vascular disorders which occur in patients with severe liver disease and/or portal hypertension. Although these syndromes are frequently diagnosed in patients undergoing assessment for liver transplantation, they seldom occur in the same patient. ⋯ HPS and PPH may coexist however they may show differing responses to liver transplantation with progression of PPH despite the resolution of HPS.
