Posterior cranial fossa is the most frequent location of pediatric brain tumors. Its diagnosis is currently performed by postsurgery histopathology and the identification of biomarkers in cerebrospinal fluid (CSF) could provide a less invasive tool. Patient CSF was collected during surgery before the tumor removal (PRE-CSF) and 6 days after the resection(More)
BACKGROUND The management of intra- and paraventricular lesions is one of the fields in which modern neuroendoscopic techniques have given the most significant contribution in terms of reduction in operative invasiveness and postoperative complications. In this context, fluid cysts represent an ideal ground on which results obtained with traditional(More)
Hyperinsulinemia and insulin resistance are common features of obesity in humans and experimental animals. It has been demonstrated that metformin, an antihyperglycemic agent, decreases hyperinsulinemia and insulin resistance leading to decreased adiposity in obese and non-insulin-dependent diabetes mellitus (NIDDM) adults. To evaluate the antiobesity(More)
AIM To assess the rate of recurrent bleeding of the small bowel in patients with obscure bleeding already undergone capsule endoscopy (CE) with negative results. METHODS We reviewed the medical records related to 696 consecutive CE performed from December 2002 to January 2011, focusing our attention on patients with recurrence of obscure bleeding and(More)
The combination of top-down and bottom-up platforms was utilized for the LC-MS proteomic characterization of the intracystic fluid of adamantinomatous craniopharyngioma pediatric brain tumor disease. Proteins and peptides characterization was achieved by high-resolution LC-ESI-LTQ-Orbitrap-MS analysis while low-resolution LC-ESI-IT-MS was applied for the(More)
Since a great deal of confusion surrounds the different uses made by clinicians, pathologists, and biologists of the term, this paper clarifies the concept of "early" cancer of the larynx. Clinically, this is usually a glottic neoplasm in which full cordal mobility is still present; early supraglottic cancer is infrequent, and usually a chance finding.(More)
The exceptional case of a 19-month-old boy with an apparently isolated frontal lesion and a huge holocord neoplastic involvement, presenting with a subtly indolent preoperative course and a particularly tumultuous evolution, is reported. The diagnosis of embryonal tumour with abundant neuropil and true rosettes was posed.
BACKGROUND The practice of endoscopic endonasal surgery is still limited in children because of the relative rarity of sellar lesions in the paediatric population. However, such an approach is increasingly reported in the literature as an alternative option to standard sublabial microsurgery, and its surgical results are being analysed. No information on(More)
BACKGROUND Adamantinomatous craniopharyngioma is the third most recurrent paediatric brain tumour. Although histologically benign, it behaves aggressively as a malignant tumour due to invasion of the hypothalamus and visual pathways. Surgery is still the first and almost the only mode of treatment, although serious damage can occur as a consequence of(More)
Malignant fibrous histiocytoma (MFH) of the upper respiratory tract is rare. We report a case of laryngeal MFH in a 78-year-old man. The patient died 8 months after the first surgical treatment. The clinicopathologic features are described, and the importance of electron microscopy and immunohistochemical techniques in the differential diagnosis with(More)
