In order to establish a sagittal plane curve reference table for standing subjects examined laterally, we determined an easily reproducible standard posture. A sample of 100 healthy subjects from 20 to 29 years of age, was chosen (43 women, 57 men). The reciprocal angulations of each vertebral body in relation to the others were fed into a digitalizer and(More)
CASE REPORT A case of the antenatal diagnosis of a craniopharyngioma with radical surgery in the neonatal period is reported. REVIEW OF THE LITERATURE We have reviewed the literature of such cases in an attempt to isolate specific features in this age group and to determine the appropriate management. Only six cases of the truly antenatal diagnosis of(More)
BACKGROUND AND PURPOSE Adjuvant treatments can be proposed in addition to surgery for patients with chronic subdural hematoma (CSDH) in order to improve the postoperative outcome. According to the survey published in 2001 by the Neurosurgery French Society, 38% of French neurosurgeons use adjuvant corticosteroid therapy after surgery. Does this adjuvant(More)
Two cases of Brown-Sequard syndrome following a stab wound of the cervical spinal cord are reported. Spinal cord hemisection was confirmed by magnetic resonance imaging and surgical exploration. Both patients presented leakage of the cerebrospinal fluid and underwent surgical repair. In the first case, the pia-mater was sutured to close the wound and(More)
BACKGROUND Skull chondroblastoma is extremely rare. We described in this study the first case of petrousal bone apex chondroblastoma. METHODS The tumor occurred in a 12-year-old girl and was revealed by left hypoacusis, vertigo, and walking instability. Computerized tomography scan depicted well-demarcated and osteolytic lesion of the left petrousal bone(More)
Neuroepithelial dysembryoplastic tumor (DNT) is usually considered as a supratentorial benign neoplasm. DNT of the posterior fossa is a very rare entity and only four previous cases were reported in the literature. We describe a case of a 26-Year-old woman presenting recurrent episodes of vertigo. Magnetic resonance imaging revealed four cystic lesions(More)
OBJECTIVE Rosai-Dorfman disease is a rare idiopathic, histiocytic, proliferative disease characterized by massive, painless cervical lymphadenopathy. Extranodal involvement is rare and central nervous system involvement is unusual. We present a patient with Rosai-Dorfman disease with spinal cord compression. Very few cases have been reported in the(More)
Exposure of "in vitro" grown immature and adult adrenal chromaffin cells to concentrations of 10(-3) or 10(-5) M but not 10(-7) M GM1 ganglioside, resulted in significant increase in cell diameter, coupled with reduction of adhesion to substrate within 48 hrs of exposure. None of the GM1 concentrations, with or without serum supplementation, did(More)
