    Supratentorial Lymphocytic Inflammation with Parenchymal Perivascular Enhancement Responsive to Steroids (SLIPPERS)-Does it Really Exist?
    (2023) FREUA, Fernando; MAHLER, Joao Vitor; LIMA, Pedro Lucas Grangeiro de Sa Barreto; NEVILLE, Iuri Santana; PORTELLA, Leonardo Barreira; MARUSSI, Victor Hugo Rocha; LANCELLOTTI, Carmen Lucia Penteado; NOBREGA, Paulo Ribeiro; SILVA, Guilherme Diogo
    Supratentorial Lymphocytic Inflammation with Parenchymal Perivascular Enhancement Responsive to Steroids (SLIPPERS) is a rare variant of the CLIPPERS spectrum with less than ten reports published so far. There is ongoing discussion regarding whether SLIPPERS is a disease entity on its own or just an acronym encompassing many underlying diagnoses, such as sarcoidosis, vasculitis and anti-glial fibrillary acidic protein (GFAP)-associated disease. A 40-year-old woman presented with episodes of language and attention impairment. Magnetic resonance imaging (MRI) revealed T2/FLAIR hyperintense lesions in the subcortical white matter associated with a micronodular, curvilinear perivascular contrast-enhancement. Alternative diagnoses were excluded. There was a remarkable response to steroids. A relapse occurred after six years, and the biopsy showed perivascular T-cell lymphocytic infiltrate, without granulomas, vasculitis, or neoplasia. There was complete resolution of the relapse after steroids. This case represents the longest reported follow-up of a patient diagnosed with SLIPPERS, and brain biopsy after 6 years did not suggest alternative diagnoses. This report contributes to the discussion regarding the possibility that exclusive supratentorial CLIPPERS-like pathology might be an isolated disease entity, but more biopsy-proven cases with a longer follow-up are needed to support this hypothesis. Recently, GFAP astrocytopathy has been characterized and might correspond to a significant number of cases previously diagnosed as CLIPPERS or SLIPPERS.

    Evaluation of Changes in Preoperative Cortical Excitability by Navigated Transcranial Magnetic Stimulation in Patients With Brain Tumor
    (2021) NEVILLE, Iuri Santana; SANTOS, Alexandra Gomes dos; ALMEIDA, Cesar Cimonari; HAYASHI, Cintya Yukie; SOLLA, Davi Jorge Fontoura; GALHARDONI, Ricardo; ANDRADE, Daniel Ciampi de; BRUNONI, Andre Russowsky; TEIXEIRA, Manoel Jacobsen; PAIVA, Wellingson Silva
    Background: This prospective study aimed to evaluate the cortical excitability (CE) of patients with brain tumors surrounding or directly involving the corticospinal tract (CST) using navigated transcranial magnetic stimulation (nTMS). Methods: We recruited 40 patients with a single brain tumor surrounding or directly involving the CST as well as 82 age- and sex-matched healthy controls. The patients underwent standard nTMS and CE evaluations. Single and paired pulses were applied to the primary motor area (M1) of both affected and unaffected cerebral hemispheres 1 week before surgery. The CE parameters included resting motor threshold (RMT), motor evoked potential (MEP) ratio for 140 and 120% stimulus (MEP 140/120 ratio), short-interval intracortical inhibition (SICI), and intracortical facilitation (ICF). Motor outcome was evaluated on hospital discharge and on 30-day and 90-day postoperative follow-up. Results: In the affected hemispheres of patients, SICI and ICF were significantly higher than in the unaffected hemispheres (p=0.002 and p=0.009, respectively). The 140/120 MEP ratio of patients' unaffected hemispheres was lower than that in controls (p=0.001). Patients with glioblastomas (GBM) had a higher interhemispheric RMT ratio than patients with grade II and III gliomas (p = 0.018). A weak correlation was observed among the RMT ratio and the preoperative motor score (R-2 = 0.118, p = 0.017) and the 90-day follow-up (R-2 = 0.227, p = 0.016). Conclusion: Using preoperative nTMS, we found that brain hemispheres affected by tumors had abnormal CE and that patients with GBM had a distinct pattern of CE. These findings suggest that tumor biological behavior might play a role in CE changes.

    Immersive virtual reality in patients with moderate and severe traumatic brain injury: a feasibility study
    (2021) MORAES, Thiago Mazzoli; ZANINOTTO, Ana Luiza; NEVILLE, Iuri Santana; HAYASHI, Cintya Yukie; PAIVA, Wellingson Silva
    Background Traumatic brain injury (TBI) remains a global health problem with cognitive impairments that can affect an individual's life. Although there is still no effective treatment for TBI sequelae, virtual reality (VR) technology shows promising results as a training tool to improve cognitive functions. Nonetheless, using a head-mounted display (HMD) device can induce cybersickness. Objective. To assess the feasibility of immersive VR cognitive training on EF and provide insights for a definitive trial. We aimed to assess the tolerability of TBI patients after prolonged use of a HMD. Also, as an exploratory analysis, we evaluated changes in cognition, including executive function, memory, and processing speed after the intervention. Methods. A prospective, single-arm, quasi-experimental study was performed to analyze the feasibility of twelve 20-min sessions of immersive VR over four weeks in patients with sustained TBI. Neuropsychological assessment was applied at baseline (T1), post-intervention (T2), and a three-months follow-up (T3). The Simulator Sickness Questionnaire (SSQ) was administered at the end of each session to evaluate the safety of the intervention. Results. Thirteen participants of mean age 34.86 (11.12), with moderate to severe TBI and average of 305.23 (51.23) days post-trauma were included. Patients showed improvements in EF between T1 and T3 (p = 0.02) and low scores in the SSQ (mean score = 4.33, SD = 4.06). Conclusions. The present VR intervention showed to be feasible and safe for patients with TBI to use a HMD. We also observed positive effects on EF and future studies should consider a home-based approach.

    Altered Intracortical Inhibition in Chronic Traumatic Diffuse Axonal Injury
    (2018) HAYASHI, Cintya Yukie; NEVILLE, Iuri Santana; RODRIGUES, Priscila Aparecida; GALHARDONI, Ricardo; BRUNONI, Andre Russowsky; ZANINOTTO, Ana Luiza; GUIRADO, Vinicius Monteiro de Paula; CUEVA, Ana Sofia; ANDRADE, Daniel Ciampi de; TEIXEIRA, Manoel Jacobsen; PAIVA, Wellingson Silva
    Background: Overactivation of NMDA-mediated excitatory processes and excess of GABA-mediated inhibition are attributed to the acute and subacute phases, respectively, after a traumatic brain injury (TBI). However, there are few studies regarding the circuitry during the chronic phase of brain injury. Objective: To evaluate the cortical excitability (CE) during the chronic phase of TBI in victims diagnosed with diffuse axonal injury (DAI). Methods: The 22 adult subjects were evaluated after a minimum of 1 year from the onset of moderate or severe TBI. Each of the subjects first had a comprehensive neuropsychological assessment to evaluate executive functions-attention, memory, verbal fluency, and information processing speed. Then, CE assessment was performed with a circular coil applying single-pulse and paired-pulse transcranial magnetic stimulation over the cortical representation of the abductor pollicis brevis muscle on M1 of both hemispheres. The CE parameters measured were resting motor threshold (RMT), motor-evoked potentials (MEPs), short-interval intracortical inhibition (SIICI), and intracortical facilitation (ICF). All data were compared with that of a control group that consisted of the healthy age-matched individuals. Results: No significant differences between the left and right hemispheres were detected in the DAI subjects. Therefore, parameters were analyzed as pooled data. Values of RMT, MEPs, and ICF from DAI patients were within normal limits. However, SIICI values were higher in the DAI group-DAI SIICI = 1.28 (1.01; 1.87) versus the control value = 0.56 (0.33; 0.69)-suggesting that they had a disarranged inhibitory system (p < 0.001). By contrast, the neuropsychological findings had weak correlation with the CE data. Conclusion: As inhibition processes involve GABA-mediated circuitry, it is likely that the DAI pathophysiology itself (disruption of axons) may deplete GABA and contribute to ongoing disinhibition of these neural circuits of the cerebrum during the chronic phase of DAI.

    The impact of urgent neurosurgery on the survival of cancer patients
    (2020) TELLES, J.P.M.; YAMAKI, V.N.; YAMASHITA, R.G.; SOLLA, D.J.F.; PAIVA, W.S.; TEIXEIRA, M.J.; NEVILLE, I.S.
    Background: Patients with cancer are subject to all neurosurgical procedures of the general population, even if they are not directly caused by the tumor or its metastases. We sought to evaluate the impact of urgent neurosurgery on the survival of patients with cancer. Methods: We included patients submitted to neurosurgeries not directly related to their tumors in a cancer center from 2009 to 2018. Primary endpoints were mortality in index hospitalization and overall survival. Results: We included 410 patients, 144 went through elective procedures, functional (26.4%) and debridement (73.6%) and 276 urgent neurosurgeries were performed: one hundred and sixty-three ventricular shunts (59%), and 113 intracranial hemorrhages (41%). Median age was 56 (IQR = 24), 142 (51.4%) of patients were metastatic, with 101 (36.6%) having brain metastasis. In 82 (33.7%) of the urgent surgeries, the patient died in the same admission. Urgent surgeries were associated with mortality in index hospitalization (OR 3.45, 95% CI 1.93–6.15), as well as non-primary brain tumors (OR 3.13, 95% CI 1.48–6.61). Median survival after urgent surgeries was 102 days, compared to 245 days in the control group (Log rank, P < 0.01). Lower survival probability was associated with metastasis (HR 1.75, 95%CI 1.15–2.66) and urgent surgeries (HR 1.49, 95% CI 1.18–1.89). Within the urgent surgeries alone, metastasis predicted lower survival probability (HR 1.75, 95% CI 1.15–2.67). Conclusion: Conditions that require urgent neurosurgery in patients with cancer have a very poor prognosis. We present concrete data on the magnitude of several factors that need to be taken into account when deciding whether or not to recommend surgery. ©2020 Published by Scientific Scholar on behalf of Surgical Neurology International

    Hemodynamic stroke caused by strangulation
    (2014) NETO, Hugo Sterman; NEVILLE, Iuri Santana; BEER-FURLAN, Andre; TAVARES, Wagner Malago; TEIXEIRA, Manoel Jacobsen; PAIVA, Wellingson Silva
    We report a case of watershed ischemic stroke in a 36-year-old male secondary to manual strangulation. The patient presented with a right hemiparesis with grade IV motor deficit and an expressive aphasia. Radiological investigation revealed an ischemic stroke on the left distal middle cerebral artery territory and in watershed areas of the left anterior and posterior cerebral arteries. There was no evidence of injury of cervical vessels. The hemodynamic mechanism and associated brain injury secondary to manual strangulation is described and discussed based on a literature review.

    Transcranial Direct Current Stimulation for Post-Concussion Syndrome: Study Protocol for a Randomized Crossover Trial
    (2017) AMORIM, Robson Luis Oliveira de; BRUNONI, Andre Russowsky; OLIVEIRA, Mirian Akiko Furutani de; ZANINOTTO, Ana Luiza Costa; NAGUMO, Marcia Mitie; GUIRADO, Vinicius Monteiro de Paula; NEVILLE, Iuri Santana; BENUTE, Glaucia Rosana Guerra; LUCIA, Mara Cristina Souza de; PAIVA, Wellingson Silva; ANDRADE, Almir Ferreira de; TEIXEIRA, Manoel Jacobsen
    Background: Mild traumatic brain injury (MTBI) represents 70-80% of all treated brain injuries. A considerable proportion of MTBI patients experience post-concussion symptoms for a prolonged period after MTBI, and these symptoms are diagnosed as persistent post-concussion syndrome (PPCS). PPCS is defined as a range of physical, cognitive, and emotional symptoms. However, memory and executive dysfunction seems to be one of the most debilitating symptoms. Recently, non-invasive brain stimulation has been studied as a potential treatment method for traumatic brain injury (TBI) patients. Therefore, our primary goal is to verify the effects of transcranial direct current stimulation (tDCS) in patients with PPCS who demonstrate cognitive deficits in long-term episodic memory, working memory, and executive function following MTBI. Methods/design: This is a randomized crossover trial of patients with a history of MTBI with cognitive deficits in memory and executive function. Thirty adult patients will be randomized in a crossover manner to receive three weekly sessions of anodal tDCS (2mA) at left dorsolateral prefrontal cortex, left temporal cortex, and sham stimulation that will be performed at 7-day intervals (washout period). The clinical diagnosis of PPCS will be determined using the Rivermead Post-Concussion Symptoms Questionnaire. Patients who meet the inclusion criteria will be assessed with a neuropsychological evaluation. A new battery of computerized neuropsychological tests will be performed before and immediately after each stimulation. Statistical analysis will be performed to determine trends of cognitive improvement. Discussion: There is paucity of studies regarding the use of tDCS in TBI patients, and although recent results showed controversial data regarding the effects of tDCS in such patients, we will address specifically patients with PPCS and MTBI and no brain abnormalities on CT scan other than subarachnoid hemorrhage. Moreover, due to the missing information on literature regarding the best brain region to be studied, we will evaluate two different regions to find immediate effects of tDCS on memory and executive dysfunction.

    Quantification of tumor induced motor cortical plasticity using navigated transcranial magnetic stimulation in patients with adult-type diffuse gliomas
    (2023) ALMEIDA, Cesar Cimonari de; NEVILLE, Iuri Santana; HAYASHI, Cintya Yukie; SANTOS, Alexandra Gomes dos; BRUNONI, Andre Russowsky; TEIXEIRA, Manoel Jacobsen; PAIVA, Wellingson Silva
    IntroductionThe evaluation of brain plasticity can provide relevant information for the surgical planning of patients with brain tumors, especially when it comes to intrinsic lesions such as gliomas. Neuronavigated transcranial magnetic stimulation (nTMS) is a non-invasive tool capable of providing information about the functional map of the cerebral cortex. Although nTMS presents a good correlation with invasive intraoperative techniques, the measurement of plasticity still needs standardization. The present study evaluated objective and graphic parameters in the quantification and qualification of brain plasticity in adult patients with gliomas in the vicinity of the motor area. MethodsThis is a prospective observational study that included 35 patients with a radiological diagnosis of glioma who underwent standard surgical treatment. nTMS was performed with a focus on the motor area of the upper limbs in both the affected and healthy cerebral hemispheres in all patients to obtain data on motor thresholds (MT) and graphical evaluation by three-dimensional reconstruction and mathematical analysis of parameters related to the location and displacement of the motor centers of gravity (Delta L), dispersion (SDpc) and variability (VCpc) of the points where there was a positive motor response. Data were compared according to the ratios between the hemispheres of each patient and stratified according to the final pathology diagnosis. ResultsThe final sample consisted of 14 patients with a radiological diagnosis of low-grade glioma (LGG), of which 11 were consistent with the final pathology diagnosis. The normalized interhemispheric ratios of Delta L, SDpc, VCpc, and MT were significantly relevant for the quantification of plasticity (p < 0.001). The graphic reconstruction allows the qualitative evaluation of this plasticity. ConclusionThe nTMS was able to quantitatively and qualitatively demonstrate the occurrence of brain plasticity induced by an intrinsic brain tumor. The graphic evaluation allowed the observation of useful characteristics for the operative planning, while the mathematical analysis made it possible to quantify the magnitude of the plasticity.

    Clinical utility of brain stimulation modalities following traumatic brain injury: current evidence
    (2015) LI, Shasha; ZANINOTTO, Ana Luiza; NEVILLE, Iuri Santana; PAIVA, Wellingson Silva; NUNN, Danuza; FREGNI, Felipe
    Traumatic brain injury (TBI) remains the main cause of disability and a major public health problem worldwide. This review focuses on the neurophysiology of TBI, and the rationale and current state of evidence of clinical application of brain stimulation to promote TBI recovery, particularly on consciousness, cognitive function, motor impairments, and psychiatric conditions. We discuss the mechanisms of different brain stimulation techniques including major noninvasive and invasive stimulations. Thus far, most noninvasive brain stimulation interventions have been nontargeted and focused on the chronic phase of recovery after TBI. In the acute stages, there is limited available evidence of the efficacy and safety of brain stimulation to improve functional outcomes. Comparing the studies across different techniques, transcranial direct current stimulation is the intervention that currently has the higher number of properly designed clinical trials, though total number is still small. We recognize the need for larger studies with target neuroplasticity modulation to fully explore the benefits of brain stimulation to effect TBI recovery during different stages of recovery.
