Randomized Controlled Trial Comparative Study
Comparison of The Efficacy of Sterile Silicone Studs vs Lidocaine for the Attenuation of the Hemodynamic Response to Skull Pin Insertion: A Randomized Controlled Trial: The role of sterile silicone studs and scalp infiltration with lignocaine in the attenuation of the hemodynamic response to skull pin insertion.
Skull pin insertion causes hypertension and tachycardia that adversely affects cerebral hemodynamics. We compared the efficacy of sterile silicone studs (SS) and pin site infiltration with lidocaine in attenuation of the sympathetic response to skull pin insertion. ⋯ Sterile SS appear to be more effective than lidocaine infiltration in attenuating the hemodynamic response to skull pin insertion with minimal adverse effects. Further multicenter studies are necessary to conclusively establish the safety and efficacy of sterile SS.

Leptomeningeal disease (LMD) is a devastating sequela of many cancers, with an extremely poor prognosis. Barriers to improving outcomes are related to the inability of many traditional therapies to effectively reach the cerebrospinal fluid (CSF) space within the central nervous system. ⋯ In this review, we highlight the principles of liquorpheresis and detail how LMD can be amenable to this treatment. Further, we summarize the current in vitro and in vivo evidence supporting liquorpheresis as a feasible method to treat LMD and other central nervous system diseases as well as describe its conceivable limitations.

Traumatic brain injury (TBI) is a highly prevalent and potentially severe medical condition. Challenges regarding TBI management are related to accurate diagnostics, defining its severity, and establishing prompt interventions to affect outcomes. Among the health care components in the TBI handling strategy is intracranial pressure (ICP) monitoring, which is fundamental to therapy decisions. However, ICP monitoring is an Achilles tendon, imposing a significant financial burden on health care systems, particularly in middle and low-income communities. This article arises from the understanding from the authors that there is insufficient scientific evidence about the potential economic impacts from the use of noninvasive technologies in the monitoring of TBI. Based on personal experience, as well as from reading other, clinically focused studies, the thesis is that the use of such technologies could greatly affect the health care system and this article seeks to address this lack of literature, show ways in which such systems could be evaluated, and show estimations of possible results from these investigations. ⋯ TBI prevalence has increased with a disproportionate health care burden in the last decades. Noninvasive monitoring techniques seem to be effective in reducing TBI health care costs, with few limitations, especially the need for more supporting scientific evidence. The undeniable clinical and financial potential of these techniques is compelling to further investigate their role in TBI management, as well as the creation of more comprehensive monitoring models to the understanding of complex phenomena occurring in the injured brain.

Keyhole surgery has been widely used to clip various intracranial aneurysms. Here, the feasibility of microsurgical clipping of multiple intracranial aneurysms via the keyhole approach was further investigated. ⋯ Early keyhole surgical clipping of multiple intracranial aneurysms is an effective treatment. Among ruptured aneurysms, small aneurysms are common and need attention and timely treatment.

Case Reports
CRANIOPLASTY WITH DIRECT REVASCULARIZATION IN HEMORRHAGIC MOYAMOYA DISEASE: 2-DIMENSIONAL OPERATIVE VIDEO.
Moyamoya disease is a progressive nonatherosclerotic stenosis of the terminal segments of the arteries of the Circle of Willis. Hemorrhagic presentation is a life-threatening condition, associated with an increased risk of rebleeding and ischemic events.1-7 We present the case of a 65-year-old woman with a right intracerebral hemorrhage who underwent emergency hematoma evacuation without bone flap replacement (Video 1). The investigation confirmed the diagnosis of Moyamoya disease and demonstrated hypoperfusion of the right cerebral hemisphere. ⋯ In the end, we sutured the temporal fascia to the titanium plate for a better cosmetic result. To avoid additional unnecessary procedures, the performance of direct revascularization during the cranioplasty is feasible and deserves additional investigation as a tool to prevent new hemorrhagic or ischemic events. Informed consent was obtained from the patient for the procedure and publication of this operative video.
