REVIEW
Pedro Castro, Elsa Azevedo, Farzaneh Sorond
PURPOSE OF REVIEW: Cerebral autoregulation (CA) is a mechanism that maintains cerebral blood flow constant despite fluctuations in systemic arterial blood pressure. This review will focus on recent studies that measured CA non-invasively in acute cerebrovascular events, a feature unique to the transcranial Doppler ultrasound. We will summarize the rationale for CA assessment in acute cerebrovascular disorders and specifically evaluate the existing data on the value of CA measures in relation to clinical severity, guiding management decisions, and prognostication...

Spontaneous intracranial hypotension (SIH) has been increasingly recognized as a phenomenon caused by cerebrospinal fluid (CSF) leaks; however, its pathogenesis is still unclear. Here, we report two cases of SIH as a result of CSF leak from a meningeal diverticulum at the C2 nerve root sleeve. The first case is that of a 46-year-old man who had suffered from orthostatic headache after a bicycle accident at age 45. Computed tomography (CT) myelography revealed CSF leaks at the C1/2 level. He underwent epidural blood patch (EBP) therapy, but it was unsuccessful...

Objective: Despite recent advances in medicine, no significant improvement has been achieved in therapeutic outcomes for severe traumatic brain injury (TBI). In the treatment of severe multiple traumas, accurate judgment and prompt action corresponding to rapid pathophysiological changes are required. Therefore, we developed the "All-in-One" therapeutic strategy for severe TBI. In this report, we present the therapeutic concept and discuss its efficacy and limitations. Methods: From April 2007 to December 2015, 439 patients diagnosed as having traumatic intracranial injuries were treated at our institution...

Background: Cerebral hemangioblastomas are benign tumors with abundant blood flow that occur mainly in the posterior fossa. Tumor removal en bloc is important in surgical treatment because of the risk of bleeding; however, it is actually rather difficult in practice. Therefore, we propose a surgical strategy for visualizing hypervascular tumors of the posterior fossa utilizing indocyanine green (ICG). Case Description: Case 1 involved a 48-year-old male with a history of von Hippel-Lindau (VHL) disease...

REVIEW
Airton Leonardo de Oliveira Manoel, R Loch Macdonald
Aneurysmal subarachnoid hemorrhage (SAH) is a sub-type of hemorrhagic stroke associated with the highest rates of mortality and long-term neurological disabilities. Despite the improvement in the management of SAH patients and the reduction in case fatality in the last decades, disability and mortality remain high in this population. Brain injury can occur immediately and in the first days after SAH. This early brain injury can be due to physical effects on the brain such as increased intracranial pressure, herniations, intracerebral, intraventricular hemorrhage, and hydrocephalus...

Two patients with ventriculoperitoneal shunts presented with symptoms of raised intracranial pressure indicative of possible shunt malfunction. During investigation, to eliminate this possibility, cerebral spinal fluid infusion studies were performed, which indicated proximal occlusion of the shunts in both cases. Retrograde flush of the ventricular catheter was performed during temporary compression of the siphon-control device, a manoeuvre which blocks distal flow. After the use of this technique, both patients' symptoms improved and they have remained symptom-free for over 2 years...

Background The optimal optic nerve sheath diameter (ONSD) cut-off for identifying increased intracranial pressure (IICP) remains unclear in adult patients. Purpose To validate the diagnostic accuracy of ultrasonographic (US) ONSD > 5.0 mm as a cut-off for detecting IICP by computed tomographic (CT) through a meta-analysis. Material and Methods A systemic literature review was performed of online databases from January 1990 to September 2017. A bivariate random-effects model was used to estimate pooled sensitivity, specificity, and diagnostic odds ratio (DOR) with 95% confidence intervals (CIs)...

In their comments, Drs. De Bernardo and Rosa stated that our paper was missing several references
 related to optic nerve sheath diameter ONSD assessments. Specifically, they state that we neglected to
 mention that ultrasound has been used since the 1970s, that we did not emphasize the role of
 Standardized A scans, and they reference some of their publications in which they emphasize the
 importance of these scans in diagnosing optic nerve lesions and benign intracranial hypertension...

Actual indications for surgery in tuberculosis are limited to obtaining a diagnosis, acquiring tissue for culture studies, treating hydrocephalus, aspiring a brain abscess, and reducing intracranial pressure in patients with multiple tuberculomas. Tuberculosis-related movement disorders are usually treated pharmacologically. We report on a child affected by post-tubercular generalized dystonia, who progressed to status dystonicus (SD) and underwent stereotactic bilateral pallidotomy. After surgery, SD resolved, and drugs were rapidly tapered...

OBJECTIVE: Subependymal giant cell astrocytomas (SEGAs) are low-grade intraventricular glial tumors that develop in 10-15% of patients with tuberous sclerosis complex; they often cause hydrocephalus and are potentially accessible to a surgical treatment. Our aim is to evaluate morbidity and results after surgery in symptomatic and asymptomatic patients. METHOD: We present a retrospective series of 18 pediatric patients operated on for SEGA between 2006 and 2016 at our institution...

Traumatic brain injury (TBI) is the leading cause of death after traumatic injury. Raised intracranial pressure (ICP) is particularly associated with poor TBI outcomes, prompting clinicians to monitor this parameter, using it to guide therapies aimed at reducing pressures. Despite this approach being recommended by several bodies such as the Brain Trauma Foundation and the American College of Surgeons, the evidence demonstrating that ICP-guided therapy improves outcome is limited. The topic was debated at the 36th Annual Point/Counterpoint Acute Care Surgery Conference and the following article summarizes the discussants points of view along with a summary of the evidence...

Neurostimulant medications are commonly prescribed following traumatic brain injury (TBI) in adults; little is known about their use in children with TBI. Our objective was to analyze neurostimulant prescribing practices from 2005 to 2015 in children admitted to the intensive care unit (ICU) with TBI. We hypothesized that neurostimulant prescriptions have increased over time and are associated with older age and injury severity. A retrospective cohort study of patients aged 1 month to 18 years with an ICD-9-CM discharge diagnosis code for TBI admitted to the ICU between 2005 and 2015 in 37 pediatric hospitals included in the Pediatric Health Information System was conducted...

Bezold's abscess is a very rare extracranial complication of acute mastoiditis. Lateral sinus thrombosis is another intracranial complication of acute mastoiditis that can occur, but there are only few reports of concomitant ispilateral Bezold's abscess and lateral sinus thrombosis with favorable outcome. We diagnosed and treated successfully a 14-year-old girl suffering from Streptococcus pneumoniae acute mastoiditis complicated with Bezold's abscess and lateral sinus thrombosis. Surgical treatment included myringotomy, cortical mastoidectomy, and Bezold's abscess incision and drainage...
