No full textSurgery around the Orbit: How to Select an Approach
No full textOrbital region pathologies may be safely and effectively treated through a various number of approaches. As the concept of "outcome" and minimally invasive surgery keeps gaining popularity in neurosurgery, these approaches-each with specific indications and limitations-together provide the best surgical options.Orbital region pathologies may be safely and effectively treated through a various number of approaches.

An Uncommon Case of Neuroenteric Cyst Located at the Lateral Cerebellomedullary Cistern
No full textWe present the case of a 42-year-old woman with a 5-week history of headache, progressive dysphagia, dysphonia, and hoarseness. A brain magnetic resonance imaging revealed an extra-axial cyst of the left lateral cerebellomedullary cistern. The subsequent histopathologic examination diagnosed a neuroenteric cyst. This case sheds light on the pivotal role of histologic identification of neuroenteric cyst, which could be crucial for further diagnostic investigations, especially in pediatric patients
Normal-pressure hydrocephalus: Twelve years experience
No full textThe authors report on twelve years experience with so-called normal pressure hydrocephalus. If care is taken to make a correct diagnosis and give adequate treatment with a shunt, hydrocephalic dementia has a good prognosis. Such cases should be distinguished from other syndromes, particularly senile dementia and Alzheimer's disease. The occurrence of a syndrome of dementia should compel every neurologist and neurosurgeon to carry out careful investigations in order to determine the favourable time for possible treatment
ECOENCEFALOGRAFIA INTRAOPERATORIA IN NEUROCHIRURGIA
No full textIntraoperative ultrasonography with real time sonographic imaging equipment is widely used and, in the neurosurgical operating room, has been really successfull, initially in the brain and subsequently in the spinal cord as well. Its main applications i.e. accurate needle biopsies, localization of intracerebral masses, placement of ventricular and cyst shunts, can diminish the amount of potential damage to normal brain tissue. Moreover results of tumor resection may be intraoperatively confirmed and the end results are more accurate. No intraoperative complications and no postoperative infections result from use of ultrasound in the operating room. No evidence is given that the small amount of mechanical vibration emitted by the transducer damages the brain or the spinal cord.Surgical procedures, as a result, are faster, safer and better planned by virtue of informations obtained by ultrasonographic intraoperative examination, instead of simple preoperative imaging procedures.Intraoperative ultrasonography with real time sonographic imaging equipment is widely used and, in the neurosurgical operating room has been really successful, initially in the brain and subsequently in the spinal cord as well.

Brain Tumours in Infants: Preferred Treatment Options
No full textSince the advent of CT scan and MRI, the diagnosis of neonatal infantile brain tumours and related diseases is more easily accomplished; their rarity is reflected in the small number of cases reported. Astrocytomas and teratomas are the most common oncotypes in infants and particularly in neonates. Surgical mortality rates are not high and have decreased because of the advances of diagnosis and improvements in treatment. However, the survival rates are disappointing. Follow-up shows little improvement in last 2 decades. Adjuvant therapy is still a problem; radiotherapy gives a small percentage of favourable later neuropsychological results. Postoperative chemotherapy added to maximal surgical resection and delayed irradiation may prolong survival with only minimal short term neurotoxicity in very young children with malignant tumours. Different protocols of chemotherapy are suggested but still not definitely accepted. Radical surgery seems to have a higher chance of success in neonates than infants and remains the less aggressive means; in low grade gliomas after total removal it may be preferable to perform a second operation if the tumour recurs and withhold irradiation and chemotherapy until after 3 years of age. © 1992, Adis International Limited.

The endoscopic diving technique in endonasal transsphenoidal surgery: how I do it
No full textThe endoscopic diving technique (EDT) is a procedure utilized in endonasal endoscopy, which consists of irrigating the surgical cavity during tumor removal, with a continuous flow of pressurized saline solution.Background: The endoscopic diving technique (EDT) is a procedure utilized in endonasal endoscopy, which consists of irrigating the surgical cavity during tumor removal, with a continuous flow of pressurized saline solution. Methods: The authors provide a detailed step-by-step description of the technique, shedding light on surgical tips and pitfalls. Advantages, disadvantages, and the most useful application of the technique are clarified and showed with a high-quality endoscopic video. Conclusion: EDT represents an effective and safe procedure. It allows a wide exploration of the surgical cavity, providing tumor hydro-dissection, assisting in bleeding control, and optimizing the efficacy of endoscopic transsphenoidal surgery
Portrait du Professeur Froeppel en linguiste folk
No full textLe but de cet article est de proposer une lecture du Professeur Froeppel dans le cadre d’une approche ‘folk linguistique’. Le protagoniste de cette oeuvre de Tardieu s'attache à beaucoup de domaines des sciences du langage et propose des synthèse originales de problèmes qui ont concerné les linguistes depuis les origines jusqu'à nos jour
