These data demonstrate the great genetic heterogeneity for the AIRE mutations in Italian APECED patients, and that the heterozygosity for AIRE mutations do not produce APECED.

The clinical use of antineoplastic drugs can be limited by different drug-induced toxicities. Of these, renal dysfunction may be one of the most troublesome in that it can be cumulative and in general is only partially reversible with the discontinuation of the treatment. Renal toxicity may be manifested as a reduction of the glomerular filtration rate, electrolyte imbalances, or acute renal failure. Careful assessment of renal function has to be performed taking into account that the impairment of renal function is initially silent and only later may be clinically dramatic. When clinically indicated, the reduction or, in cases of severe nephrotoxicity, the suspension of chemotherapy should be considered to avoid the progressive deterioration of the compromised glomerular and/or tubular function.

High-grade gliomas are the main cause of death in children with brain tumours. Despite recent advances in cancer therapy, their prognosis remains poor and the treatment is still challenging. To date, surgery followed by radiotherapy and temozolomide is the standard therapy. However, increasing knowledge of glioma biology is starting to impact drug development towards targeted therapies. The identification of agents directed against molecular targets aims at going beyond the traditional therapeutic approach in order to develop a personalized therapy and improve the outcome of pediatric high-grade gliomas. In this paper, we critically review the literature regarding the genetic abnormalities implicated in the pathogenesis of pediatric malignant gliomas and the current development of molecularly targeted therapies. In particular, we analyse the impact of molecular biology on the prognosis and treatment of pediatric high-grade glioma, comparing it to that of adult gliomas.

MPI value is a sensitive and accurate parameter, allowing subclinical cardiac dysfunction to be detected in children receiving anthracyclines. Lifelong cardiac surveillance of these patients is warranted in order to determine the clinical implications of increased MPI on long-term cardiac status.
