Case Reports
Primary anaplastic glio-neuronal tumor of the pineal gland: a new type of pineal neoplasm?
Tumors of the pineal gland are relatively rare. Most are solid, infiltrative lesions characterized by either germ cell, glial, or pineal parenchymal origin. To our knowledge, none have been described that contain an admixture of both anaplastic glial and neuronal elements. ⋯ We present the first case of a primary anaplastic glio-neuronal neoplasm of the pineal gland. Increased use of immunostaining may unveil additional cases in the future. Furthermore, additional research will be required to determine whether the dual differentiation has prognostic significance.

Post-operative cerebrospinal fluid (CSF) fistula following neurosurgery is associated with increased morbidity and mortality. This prospective study evaluates the efficacy of a new bioadhesive--BioGlue, as a dural sealant in preventing CSF fistula. The complications associated with its use are investigated and the literature regarding dural closure reviewed. ⋯ BioGlue reduced the incidence of complications associated with neurosurgery. It is an effective adjunct in dural closure to prevent CSF fistula with enhanced bonding properties and is simple to use. In this study there were no complications associated with its use.

A moving correlation index (Mx-ABP) between arterial blood pressure (ABP) and mean middle cerebral artery blood flow velocity (CBFV) can be used to monitor dynamic cerebrovascular autoregulation (CA) after traumatic brain injury (TBI). In this study we examined hemispheric CA asymmetry and temporal CA profiles, their relationship with ABP and CBFV, and their prognostic relevance. Mx-ABP was calculated for each hemisphere in 25 TBI patients second-daily for as long as they were receiving sedation and analgesia. ⋯ It does not bear significant clinical or predictive relevance, and it is unrelated to CBFV or ABP. CA is most profoundly disturbed during the immediate postinjury phase and improves gradually during the ICU course. Further studies are needed to investigate CA during post ICU recovery and rehabilitation.
