Neuro-endoscopic management of intraventricular neurocysticercosis (NCC).
Various approaches including endoscopy have been used for the treatment of intraventricular and cisternal NCC. We present our technique of Neuro-endoscopic management of intraventricular NCC. ⋯ Neuro-endoscopic surgery is an effective treatment modality for patients with intraventricular NCC. It effectively restores CSF flow and is capable of removing cysts completely or partially from accessible locations causing mass effect. Partial removal or rupture of the cyst does not affect the clinical outcome of the patients.

Chiari I malformation associated with atlanto-axial dislocation: focussing on the anterior cervico-medullary compression.
Chiari I malformation with atlantoaxial dislocation may cause both posterior and anterior cervicomedullary compression. We studied the clinicoradiological features and surgical outcome in patients having Chiari I malformation with atlantoaxial dislocation. ⋯ Patients with Chiari I malformation should be investigated for the presence of atlanto-axial dislocation. In case atlantoaxial dislocation coexists, priority must be given to relieving anterior cervicomedullary compression.

Randomized Controlled Trial Multicenter StudyEffects of the selective endothelin A (ET(A)) receptor antagonist Clazosentan on cerebral perfusion and cerebral oxygenation following severe subarachnoid hemorrhage - preliminary results from a randomized clinical series.
To study the effects of clazosentan, a new selective endothelin receptor subtype A antagonist, on cerebral perfusion and cerebral oxygenation following severe aneurysmal subarachnoid haemorrhage (aSAH). ⋯ These preliminary data suggest that clazosentan reduces the extent of vasospasm-associated impairment of cerebral perfusion following aSAH. Furthermore, clazosentan may exert beneficial actions on overt vasospasm-associated hypoperfusion.

Objective criteria for successful transsphenoidal removal of suprasellar nonfunctioning pituitary adenomas. A prospective study.
Despite ample experience with transsphenoidal surgery, objective data on which suprasellar tumour expansion and growth pattern allows for radical adenoma resection are still sparse. Hence, we have performed a prospective study to establish the predictive value of tumour dimension and shape for the intra-operative descent of the diaphragma, the completeness of tumour resection and the outcome of patients harbouring pituitary adenomas with suprasellar extension. ⋯ One-stage transsphenoidal surgery allows total or near-total resection of most suprasellar pituitary adenomas with low surgical morbidity. Quantitative assessment of tumour dimension and configuration contributes to establishing guidelines for the selection of the appropriate approach and prediction of surgical outcome.

Review Case ReportsDural arteriovenous malformation: an unusual cause of trigeminal neuralgia.
Trigeminal neuralgia has been rarely reported in association with dural arteriovenous malformations (DAVMs). We describe a case of trigeminal neuralgia resulting from compression of the trigeminal nerve at its root entry zone by a large tentorial DAVM. Surgical interruption of the draining vein at its exit from the tentorium resulted in complete angiographic obliteration of the fistula with immediate resolution of the facial pain. We review the literature relevant to this topic and discuss the aetiology and pathophysiology of trigeminal neuralgia as well as the management of tentorial DAVMs.
