Brain metastases from thyroid carcinoma is unusual, with a frequency of 1%. We report twelve patients, with single brain metastases and with a karnofsky performance scale score >60 at admission. No metastasis was seen during the uptake of iodine-131, even in the cases from differentiated thyroid carcinoma, suggesting absence of differentiation between(More)
BACKGROUND The aim of the present study is to present our operative method of removing organized CSDHs and to structure the criteria for choosing this approach as first treatment. METHODS Between 1991 and 1999 at our Institution, 14 consecutive patients with organized CSDHs required 16 craniotomies with membranectomy. They represent 5.8% of all patients(More)
Cerebral meningiomas are rare tumors in children that represent 1.4% of CNS tumors and 1.5% of intracranial meningiomas. We have analyzed 197 cases of cerebral meningiomas under 16: 178 cases were taken from the available literature and 19 from our series. When comparing pediatric meningiomas with those of adults, we noted some differences. Before the age(More)
OBJECT To evaluate the role of local inflammation in the pathogenesis and postoperative recurrence of chronic subdural hematoma (CSDH), the authors conducted an investigation in a selected group of patients who could clearly recall a traumatic event and who did not have other risk factors for CSDH. Inflammation was analyzed by measuring the concentration of(More)
OBJECTIVE Despite increased information on the importance of an inappropriate inflammatory response in the acute Charcot process, there has been no previous attempt to define the specific pathways that mediate its pathogenesis. Here, the role played by monocytes was analyzed. RESEARCH DESIGN AND METHODS The immune phenotype of peripheral monocytes was(More)
The purpose of this study was to investigate the characteristics of childhood acute epidural hematoma and to report our experience in recent years. A series of 35 patients below the age of 15 years treated for acute epidural hematoma at our institution between June 1991 and December 2000 was analyzed in detail. Pediatric epidural hematoma presents both(More)

BACKGROUND A large variety of biologic and artificial materials have been suggested as dural substitutes. However, no ideal material for dural repair in neurosurgical procedures has been identified. The authors report their experience with Tutoplast processed dura and pericardium. METHODS This study is designed to evaluate Tutoplast dura and pericardium.(More)
Neurinomas of the hypoglossal nerve extending extra-cranially are rare; a schwannoma in a 63-year-old woman causing nerve palsy is reported. The tumour presented as a slow-growing mass in the right submandibular space; a surgical approach with transcervical exploration was performed. The post-operative course was uneventful.
BACKGROUND In patients submitted to suboccipital craniectomy in whom the bone is not repositioned, there may be a significant aesthetic defect due to lack of bone tissue, sometimes accompanied by paresthaesia and painful symptoms. METHOD In 15 patients submitted to suboccipital craniectomy, the bone chips were repositioned during wound closure. FINDINGS(More)
