The peculiar radiological and pathological findings of four pediatric cases admitted to the University Hospital of Padua between 1990 and 2007 are described. In all cases, the contrast-enhanced head and spine magnetic resonance images revealed thickened and abnormally enhancing subarachnoid spaces particularly at the level of basal cisterns and(More)
PURPOSE Hepatoblastoma (HB) is a rare malignant liver tumor which occurs almost exclusively in childhood. In the 1970s, survival was approximately 20% to 30%. Since the introduction of cisplatin (PLA) and doxorubicin (DO) into the chemotherapy regimens used to treat these patients, the survival rate has improved dramatically. In most recent studies, primary(More)
The principal aim of this report is to present the results of multivariate analyses conducted to identify clinical prognostic factors in 92 children aged < 16 years with ependymoma (EPD) retrospectively collected in seven Italian centres. They were treated over a 16-year period (1977-1993). Treatment modalities varied. Surgery and radiotherapy (RT) was the(More)
Approximately 80% of tumors arising in the brain stem are diffuse intrinsic lesions. Patients typically present with a short duration of symptoms and signs with significant neurological impairment. Imaging findings are typical, and biopsy is not usually necessary to make a diagnosis. Standard treatment consists of radiotherapy alone. Although the majority(More)
OBJECTIVE Juvenile localized scleroderma is a chronic progressive fibrotic disorder of the skin that causes permanent disability and aesthetic damage. This study was undertaken to assess the safety and efficacy of methotrexate (MTX) in the treatment of juvenile localized scleroderma. METHODS In this double-blind study, patients with active juvenile(More)
The treatment of childhood low grade glioma (LGG), if not amenable to complete resection, quite often is a relevant clinical challenge. LGG in many instances are indeed slow growing tumors, which, if not controlled, can cause severe morbidity and ultimately jeopardize life. Most of the time children bearing an unresectable LGG can be considered affected by(More)
The treatment of hepatoblastoma is an example of the great advances made in paediatric oncology over the past few decades. Formerly a disease with a dreadful prognosis, children now have a 5-year survival rate of over 70%. This has been achieved by advances in surgical techniques and the use of chemotherapy. In future, we hope to be able to improve survival(More)
OBJECTIVE Although endoscopic third ventriculostomy (ETV) is a well established procedure for the treatment of congenital and acquired hydrocephalus, there is still a controversy with regard to the higher risk of failure in younger infants compared to older children after such a procedure. The aim of this article is to define the effectiveness of third(More)
OBJECT Some medulloblastomas (MBs) are characterized by extreme nodularity and intranodular nuclear uniformity in a fine fibrillary background. These lesions have also been designated as "cerebellar neuroblastoma." Although numerous reports have been published in which their morphological features have been investigated, only a few studies have been focused(More)
