ABSTRACT
ABSTRACT In the present paper we summarize the suggestions of a multidisciplinary group including experts in pediatric oncology and infectious diseases who reviewed the medical literature to elaborate a consensus document (CD) for the diagnosis and clinical management of invasive fungal diseases (IFDs) in children with hematologic cancer and those who underwent hematopoietic stem-cell transplantation. All major multicenter studies designed to characterize the epidemiology of IFDs in children with cancer, as well as all randomized clinical trials addressing empirical and targeted antifungal therapy were reviewed. In the absence of randomized clinical trials, the best evidence available to support the recommendations were selected. Algorithms for early diagnosis and best clinical management of IFDs are also presented. This document summarizes practical recommendations that will certainly help pediatricians to best treat their patients suffering of invasive fungal diseases.

AIM: To assess the late cardioprotective effect of dexrazoxane associated with doxorubicin during treatment of osteosarcoma by means of low-dose dobutamine stress echocardiography (LDDSE) in non-relapsed asymptomatic children and teenagers. PATIENTS AND METHODS: The study population included 58 patients with osteosarcoma divided in three groups, with equivalent age range, gender proportion and body surface area. Group I (21 patients, 14 males, 15 +/- 4 years) was analyzed before chemotherapy and considered the control group; Group II (19 patients, 11 males, 19.7 +/- 4 years) was treated with 348.4 +/- 18 mg/m2 of doxorubicin only and Group III (18 patients, 14 male, 16.8 +/- 5 years) treated with 396.5 +/- 55 mg/m2 of doxorubicin with dexrazoxane in the ratio 10:1. The patients were submitted to LDDSE (maximal dose 5 microg/kg/min). No major side effects were observed. Heart rate, blood pressure, left ventricular diameters, end systolic wall stress (ESWS), and other diastolic and systolic function indexes were assessed at rest conditions and during LDDSE and compared between the three groups. RESULTS: Group III received a doxorubicin dose significantly greater than Group II (P = 0.001). During LDDSE there were no significant changes in the diastolic function indexes in any of the groups, but there was a significant increase of systolic indexes and a decrease of ESWS in Group III compared to group II. There was no significant difference of any systolic functional parameters between Group I and III. Considering the ejection fraction (EF) at rest or at LDDSE, 13 patients (69.4%) in Group II and 5 patients (27.7%) in Group III were considered to have systolic dysfunction. (P = 0.02). CONCLUSION: Myocardial response to LDDSE in patients treated with doxorubicin and dexrazoxane was similar to patients without chemotherapy and better than those treated with doxorubicin only, suggesting less cardiotoxicity.
