We verified the variations of primary tumour steroid receptor status and proliferative activity at different times and phases (follicular vs luteal) of the menstrual cycle and their relationship with short clinical outcome in a cohort of 248 N- breast cancer patients. Steroid receptor content (ER and PgR) was evaluated by DCC assay and proliferative(More)
Glioblastoma Multiforme, the most common and aggressive primary brain tumor, remains incurable despite of the advent of modern surgical and medical treatments. This poor prognosis depends by the recurrence after surgery and intrinsic or acquired resistance to chemotherapy and radiotherapy. Nitric oxide is a small molecule that plays a key roles in glioma(More)
Malignant brain tumours are one of the most relevant causes of morbidity and mortality across a wide range of individuals. Malignant glioma is the most common intra axial tumor in the adult. Many researches on this theme brought advances in the knowledge of gliomas biology and pathogenesis and to the development of new agents for targeted molecular therapy.(More)
Glioblastoma multiforme (GBM) is the most frequent primary central nervous system (CNS) tumor. Despite the best treatment and advances in therapy, prognosis remains poor. One of the mainstays of therapy in GBM is surgical excision. Several studies have confirmed that the extent of resection (EOR) positively influences overall survival (OS) in patients with(More)
Pregnancy is a recognized risk factor for aneurysmal subarachnoid hemorrhage (SAH). Headache is very frequent in normal pregnancy and it is a common sign shared between several intracranial diseases. We present a case series of 10 women in the third trimester of pregnancy admitted to our intensive care unit (ICU) with neurological signs and symptoms. 4 of(More)
$EVWUDFW A number of actions have been recently proposed, aiming at filling the gap existing in the availability of speech annotated corpora of Italian regional varieties. A starting action is represented by the national project AVIP (Archivio delle Varietà di Italiano Parlato, Spoken Italian Varieties Archive), whose main challenge is a methodological one,(More)
p53 mutations have been reported to correlate with prognosis and response to therapy in patients with different tumor types. However, although p53 status is related to the primary tumor aggressiveness, an association between its expression and specific metastatic pattern has not yet been investigated. We immunohistochemically analyzed p53 (Pab1801) and ki67(More)
PURPOSE a literature review was made to investigate the role of nitric oxide (NO) in spinal cord injury, a pathological condition that leads to motor, sensory, and autonomic deficit. Besides, we were interested in potential therapeutic strategies interfering with NO mechanism of secondary damage. MATERIALS A literature search using PubMed Medline database(More)
The introduction of modern endoscopy in neurosurgery brought light to one of the darkest areas: the skull base. In particular, the trans-nasal route allowed skull base surgeons to visualize and dominate the entire midline skull base. We analyzed our surgical series of 199 patients that were affected by several pathologies (pituitary adenomas,(More)
Malignant glomus tumors (GTs) are rare, and diagnosis requires consideration of specific histologic criteria. Glomus tumors that do not fulfill the histologic criteria for malignancy but show at least 1 feature other than nuclear atypia should be classified as GTs of uncertain malignant potential (GTUMPs). We report the case of a 74-year-old man with a(More)
