Olfactory groove meningiomas (OGM) account for 4.5% of all intracranial meningiomas. We report 21 patients with OGMs. Tumors were operated on using three surgical approaches: bifrontal (7 patients), fronto-pterional (11 patients) and fronto-orbital (3 patients). Total tumor removal (Simpson Grade 1) was achieved in 13 patients and Simpson II in 8 patients.(More)
Formalin-fixed, paraffin-embedded surgical specimens from 55 meningiomas were immunostained with monoclonal antibody against p53 (Immunotech, Marseilles, France). There were 38 women and 17 men ranging between 9 and 82 years of age. The patients were divided into two groups: group I (47 patients) – mildly symptomatic and group II (eight patients) – severe(More)
BACKGROUND Cerebral vasospasm after subarachnoid hemorrhage (SAH) is a major cause of morbidity and mortality. We studied the effects of clot removal on multiple outcome variables following the clipping of ruptured anterior communicating aneurysms. METHODS From 2007 to 2011, 30 patients with Fisher grade III aneurysmal SAH underwent clipping of an(More)
To elucidate immunopathogenetic roles of aquaporin-4 antibodies in the cerebrospinal fluid (CSF) of neuromyelitis optica spectrum disorders (NMOSD), we analyzed aquaporin-4 antibody titers, cellular and inflammatory markers in the CSF collected from 11 aquaporin-4 antibody seropositive patients. The CSF aquaporin-4 antibody levels during attacks (but not in(More)
BACKGROUND Vasospasm is an important complication observed after subarachnoid hemorrhage (SAH) and is a frequent cause of mortality and morbidity. We present our routine management of vasospasm after SAH and emphasize the importance of transcranial Doppler (TCD) ultrasonography in this management. METHOD Historical records and images were sampled from(More)
Glossopharyngeal neuralgia is an uncommon craniofacial pain syndrome that is occasionally associated with cardiac syncope. However, we relate Chiari I syndrome as a cause of this clinical picture for the first time in the literature. The authors analyze the relevant literature and discuss the pathogenesis and treatment of associated syndromes. We describe(More)
Objective: To evaluate clinical features among patients with neuromyelitis optica spectrum disorders (NMOSD) who have myelin oligodendrocyte glycoprotein (MOG) antibodies, aquaporin-4 (AQP4) antibodies, or seronegativity for both antibodies. Methods: Sera from patients diagnosed with NMOSD in 1 of 3 centers (2 sites in Brazil and 1 site in Japan) were(More)
Thirty men having Parkinsons disease (PD) and 30 controls were studied prospectively by the use of the International Index of Erectile Function (IIEF) to assess erectile dysfunction (ED). Of the patients with PD (mean age of 59 years), 46.66% referred to the practice of sexual activity. All of the parkinsonians were using antiparkinsonian medication. In the(More)
The purpose of this study was to determine the relationship between perception of verticality and balance disorders in multiple sclerosis patients. We evaluated patients and healthy controls. Patients were divided into two groups according to their risk of fall, with or without risk of fall, measured by a Dynamic Gait Index scale. Graviceptive perception(More)
Previously reported only a few times before, we present a case of extracranial vertebral dissection and spontaneous frontoparietal subarachnoid hemorrhage (SAH) in the puerperium, discussing possible mechanisms and difficulties in management. A 35-year-old woman presented 10 days postcaesarean section with neck pain and vertigo with normal initial(More)
