Conventionally, neuroendoscopic excision of intraventricular tumors has been difficult and time consuming because of lack of an effective decompression system that can be used through the working channel of the endoscope. ⋯ The NICO Myriad is a highly effective tumor decompression system that can be effectively used in a purely endoscopic approach to intraventricular lesions.

Different mechanisms are introduced for various kinds of spine fractures. Falls from walnut trees are a major cause of spine fracture, with a high rate of mortality and significant deficits in young male workers. The aim of this study was to define the rate of cervical fractures and pattern of fractures in falls from walnut trees and to compare with other types of falls in the literature, which seem to have different mechanisms. ⋯ The pattern of fractures was unique to falls from walnut trees, mainly consisting of cervical fractures with quadriplegia and a poor prognosis, and in a young group of workers, which puts a large economic burden on society.

To assess long-term efficacy of the gasket seal, a method for watertight closure of the cranial base using autologous fascia lata held in place by a rigid buttress, in a large case series. ⋯ Gasket seal closure is a reliable long-term effective method for achieving watertight closure of the cranial base. It can be used in association with an intracranial fat graft, NS flap, LD, and tissue sealants. In this series, none of these other factors were significant predictors of postoperative CSF leak.
