RESUMO
Background and Objectives: Mortality index is the ratio of observed-to-expected mortality. Accurate and thorough documentation of patient comorbidities and conditions is the key determinant of neuroscience expected mortality. In this study, we focused on reviewing neuroscience documentation, as optimizing mortality index provides accurate assessment of the quality of care provided, improves service-line rankings, and affects reimbursement. Methods: We assembled an interprofessional team of a neurologist and clinical documentation integrity (CDI) specialists to review clinical documentation of all mortalities from the neuroscience service lines at a tertiary academic medical center over 9 months. We identified common documentation opportunities among high acuity neuroscience patients to improve accuracy of expected mortality. Using the mortality risk adjustment method from Vizient Inc., we compared baseline and postreview expected mortality. Results: We reviewed 70 mortality charts over a 9-month period. Opportunities to improve documentation were present in 60%. Common underreported comorbidities included aspiration pneumonia, shock, encephalopathy, thrombocytopenia, hemorrhagic disorder due to anticoagulation, and nontraumatic subarachnoid hemorrhage. The number of diagnoses identified per patient that affected mortality increased between the first and last quarter from 4.3 to 7.8 (p < 0.0001). Physician-identified additional diagnoses per patient decreased from 1.0 to 0.3 (p = 0.0037), as CDI specialists had increased capture of neuroscience specific diagnoses throughout the intervention. The average expected mortality significantly increased from baseline 0.33 to 0.42 (p < 0.0001). Discussion: Collaboration between physicians and CDI specialists optimizes expected mortality by identification of common gaps in documentation specific to neuroscience patients. Neurologist engagement is beneficial in CDI and lays the framework for clinical documentation education for neurology physicians.
RESUMO
INTRODUCTION: Bromocriptine is a dopamine receptor agonist used for central hyperthermia with limited data. We describe our single-center experience utilizing bromocriptine for central hyperthermia, including the population treated, most common dosing regimens, adverse events, and discontinuation reasons. METHODS: A retrospective study was conducted screening patients who were admitted to intensive care units for acute neurological insults and administered bromocriptine for central hyperthermia between April 2016 and September 2022. Baseline characteristics, disease severity markers, and bromocriptine doses were collected. Body temperatures prior to the first dose of bromocriptine, at the time of dose, and after each dose were recorded. Co-administration of additional hyperthermia management therapies was noted. RESULTS: Thirty patients were included. The most common diagnosis was traumatic brain injury (TBI) (N = 14). The most common reason for discontinuation was resolution of indication (N = 14). Discontinuation due to mild adverse effects occurred in four patients; hepatotoxicity was the most common. There was a paired mean difference of -0.37°C (p = 0.005) between temperatures before and after bromocriptine initiation. CONCLUSION: Bromocriptine is a potential therapy for the management of central hyperthermia in patients with severe acute neurologic insults who have failed other therapies. Bromocriptine was well tolerated and associated with a low incidence of adverse events.

Background: This is a case of multifocal intracranial stenosis in a 74 year old male ultimately discovered to be due to Varicella Zoster Virus infection. Purpose: We highlight the importance of a broad differential diagnosis, even when the most likely etiology of intracranial stenosis is atherosclerosis. Our paper reviews the differential diagnosis as well as "red flags" for intracranial vasculopathy. Even though intracranial atherosclerotic disease is the most common cause of vasculopathy, infectious or inflammatory vasculitis should be considered on the differential. Conclusions: Before considering bypass surgery or other invasive neurosurgical procedures, ensure reversible causes of vasculopathy have been ruled out. The presence of cranial neuropathies, rash, and/or elevated inflammatory markers should be red flags for vasculitis in patients presenting with stroke.

Paediatric high-grade gliomas, including glioblastoma and anaplastic astrocytoma, make up 8%-12% of paediatric central nervous system tumours 1 and have poor prognosis, with 2-year survival less than 30% 2 and overall survival less than 10%. The only known prognostic factors in this population include extent of resection and tumour histological grade. We present the case of a 9-year-old boy with disseminated anaplastic astrocytoma treated with subtotal resection, craniospinal radiation and temozolomide, with 8-year survival despite metastatic disease at presentation and subtotal resection. Next generation cancer gene panel sequencing revealed an usual pattern of 12 amplifications and four mutations not previously described.

We present the case of a 13-year-old boy with a very unusual periventricular atypical central neurocytoma with unique molecular features treated with subtotal surgical resection and photon intensity-modulated radiotherapy. Histological features were most consistent with atypical central neurocytoma. However, next-generation sequencing analysis revealed a novel EWSR1-ATF1 gene fusion (EWSR1-ATF1) as well as a MUTYH mutation. The EWSR1-ATF1 raised the possibility of Ewing sarcoma or angiomatoid fibrous histiocytoma, however, FLI-1 immunohistochemistry was negative. MUTYH mutations have been reported in diffuse midline paediatric glioma. The role of EWSR1-ATF1 and MUTYH mutations in central nervous system tumours is not well established. We present the first case of EWSR1-ATF1 and MUTYH mutation in a rare paediatric atypical central neurocytoma. Further studies are indicated to elucidate the consequences of these gene alterations in the context of paediatric central nervous system tumours as well as to investigate the potential role for targeted therapies.

INTRODUCTION: Hyperbaric oxygen therapy (HBOT) has been utilized as adjunctive treatment of CNS tumors and for radiation necrosis (RN) with reported success. The safety and efficacy in pediatric patients is less understood. METHODS: Seven patients (ages 10-23 years, six females) were treated with HBOT (3-60 sessions) for either RN (n = 5) or tumor-associated edema (n = 2). Tumor diagnosis included low-grade glioma (n = 4, two with neurofibromatosis type 1), meningioma (n = 1), medulloblastoma (n = 1) and secondary high grade glioma (n = 1). Prior therapies included: surgery (n = 4), chemotherapy (n = 4) and radiation (N = 5: four focal, one craniospinal). Three underwent biopsy: one confirming RN, one high-grade glioma, and one low-grade glioma. Patients were assessed for clinical and radiographic changes post HBOT. RESULTS: Median time to clinical and radiographic presentation was 8.5 months (range 6 months-11 years) in those who had prior radiation. Clinical improvement after HBOT (median: 40 sessions) was observed in four of seven patients. Symptoms were stable in two and worsened in one patient. Radiographic improvement was seen in four patients; three had radiographic disease progression. In the subgroup treated for presumed and biopsy-confirmed RN (n = 5), four of five (80%) had clinical and radiographic improvement. There were no long-term adverse events due to HBOT. CONCLUSIONS: HBOT is safe and well-tolerated in pediatric and young adult patients with CNS tumors. Clinical and radiographic improvements were observed in over half of patients. Clinical trials are needed to establish safety and efficacy of HBOT as adjunct therapy in pediatric CNS tumors.

Severe neuropathy is a known adverse effect of vincristine in patients with Charcot-Marie-Tooth disease (CMT). We present the case of a 16-year-old girl with anaplastic medulloblastoma treated with gross total resection and high-dose craniospinal radiation with adjuvant vincristine chemotherapy who developed acute-onset severe quadriplegia and vocal cord paralysis. Vincristine and radiation therapy were discontinued. Although her neuropathy slowly improved over several weeks, she developed metastatic extraneural medulloblastoma and died 5 months after diagnosis. Subsequent genetic testing revealed previously asymptomatic and undiagnosed CMT1A. Our case highlights the importance of early recognition of acute vincristine neurotoxicity that should raise suspicion of an underlying hereditary neuropathy.
