Intravascular lymphomatosis (IVL) is a rare, malignant B- or T-cell lymphoma with remarkable affinity for the endothelial cells of small vessels, particularly within the skin and central nervous system. It is a disease that mimics several neurological disorders, particularly those of cerebrovascular ischemic origin. The prognosis is generally poor, with a(More)
Purpose We performed a new phase II trial enrolling patients with newly diagnosed high-grade glioma (HGG) to test the efficacy of a weekly alternating temozolomide (TMZ) schedule after surgery and concomitant chemoradiotherapy. Methods From January 2005 to January 2007, 34 patients (21 men, 13 women; age range 30–70, mean age 53) were enrolled. There were(More)
issociated dorsal root ganglion cells from human fetuses were exposed to 2,5-hexanedione (2,5-HD) for 2 weeks. Morphological changes induced by 2,5-HD consisted in focal neurofilament (NF)-containing enlargements preferentially located in distal, preterminal regions of unmyelinated fibers. Tangles of NF were also observed in the perikarya of nerve cells.(More)
18p- syndrome from chromosomal deletion of the short arm of chromosome 18 shows a wide range of clinical manifestations. Mental retardation is the most frequent neurological complication; other neurological deficits are more rarely reported. Only one 18p- patient with focal dystonia at the lower limbs has been reported, while there have beenno reported(More)
A 50-year-old male law teacher came to our observation complaining of a progressive walking impairment and mood changes lasting seven months. In fact, he had become more introverted, showing no interest in his work or social life. No neurological disorders were reported in the family and his past history was unremarkable. Neurological examination disclosed(More)
A 45-year-old female patient developed a malignant peripheral nerve sheath tumour (MPNST) arising from the left brachial plexus, ten years after regional radiation treatment for Hodgkin's disease. The clinical course was characterized by local recurrence, pulmonary and cerebral metastases with endocranic hypertension syndrome, and the death of the patient(More)
Choreoathetotic syndromes are frequently observed in children after congenital cardiopathy surgery. To report the case of an adult patient who developed a choreoathetotic syndrome after cardiac operation, probably related to a transitory hypometabolism of basal ganglia. A 52-year-old patient underwent heart surgery under circulatory arrest and deep(More)
Leptomeningeal metastasis (LM) is a severe complication in the natural history of malignancies that occurs in 4–15 % of patients (pts) with solid tumors. Clinical presentation, cerebrospinal fluid cytology (CSF), and gadolinium magnetic resonance imaging (gdMRI) of the brain and spine are the methods routinely used to diagnose LM. Treatment encompasses(More)
Doppel (PRND) is a paralogue of the mammalian prion (PRNP) gene. It is abundant in testis and, unlike PRNP, it is expressed at low levels in the adult central nervous system (CNS). Besides, doppel overexpression correlates with some prion-disease pathological features, such as ataxia and death of cerebellar neurons. Recently, ectopic expression of doppel(More)
