Pierre-Alexis Lépine, Jean-François Naud, Philippe Boisvert
A 62-year-old man presented to the emergency department with massive hemoptysis. After bronchial artery embolization, he developed ischemic myelitis, a rare complication in this setting for which no specific therapy is currently recommended. The symptoms were managed with lumbar drainage of cerebrospinal fluid and blood pressure augmentation therapy. To our knowledge, this is the first report of using lumbar drainage of cerebrospinal fluid and blood pressure augmentation in the treatment of anterior medullary ischemia after bronchial artery embolization for massive hemoptysis...

REVIEW
Curtis L Johnson, Eva H Telzer
Magnetic resonance elastography (MRE) is a quantitative imaging technique for noninvasively characterizing tissue mechanical properties, and has recently emerged as a valuable tool for neuroimaging. The measured mechanical properties reflect the microstructural composition and organization of neural tissue, and have shown significant effects in many neurological conditions and normal, healthy aging, and evidence has emerged supporting novel relationships between mechanical structure and cognitive function. The sensitivity of MRE to brain structure, function, and health make it an ideal technique for studying the developing brain; however, brain MRE studies on children and adolescents have only just begun...

OBJECTIVE: This study aimed to investigate whether clinical parameters and serum neuron-specific enolase (NSE) levels measured at emergency department (ED) presentation help stratify the risk of acute or delayed persistent severe neurological sequelae after acute carbon monoxide (CO) poisoning induced by charcoal burning. METHODS: This retrospective study included 236 patients who suffered from CO poisoning. Demographic information, serum NSE levels measured in the ED, treatment, clinical course, and long-term neurological outcomes were recorded...

Multiple accounts have been proposed to explain category-specific recognition impairments. Some suggest that category-specific deficits may be caused by a deficit in recurrent processing between the levels of a hierarchically organized visual object recognition system. Here, we tested predictions of interactive processing theories on the emergence of category-selective naming deficits in neurologically intact observers and in patient GA, a single case showing a category-specific impairment for natural objects after a herpes simplex encephalitis infection...

Synthetic cannabinoids refer to a wide variety of chemicals engineered to bind cannabinoid receptors (CB1 and CB2) and mimic the effects of delta-9-tetrahydrocanabinol. The potential for severe toxicity and limited in vivo data make synthetic cannabinoid intake an important public health and safety concern. Neurologic toxidromes associated with their use include mental status changes, panic attacks, memory distortions, acute psychosis (e.g. paranoia, delusional thoughts), disorganized behavior, and suicidal and homicidal thoughts...

Acute bacterial meningitis is a medical emergency, and delays in initiating effective antimicrobial therapy result in increased morbidity and mortality. Culture-based methods, thus far considered the "gold-standard" for identifying bacterial microorganisms, require 24 to 48 hours to provide a diagnosis. In addition, antimicrobial therapy is often started prior to clinical sample collection, thereby decreasing the probability to culturally confirm the bacterial pathogen. To enable a fast and accurate detection of the most important bacterial pathogens causing meningitis, namely S...

The gut-brain axis communicates the brain with the gut microbiota, a bidirectional conduit that has received increasing attention in recent years thanks to its emerging role in brain development and function. Alterations in microbiota composition have been associated to neurological and psychiatric disorders, and several studies suggest that the immune system plays a fundamental role in the gut-brain interaction. Recent advances in brain imaging and in microbiome sequencing have generated a large amount of information, yet the data from both these sources needs to be combined efficiently to extract biological meaning, and any diagnostic and/or prognostic benefit from these tools...

BACKGROUND: The goal of intraoperative neurophysiologic monitoring (IONM) is to minimize neurologic injury during surgery, yet patients still emerge with postoperative deficits. Few studies focus on outcomes relative to IONM alarms and interventions in this population. The authors sought to analyze the influence of IONM alarms with and without surgical intervention on patient outcome in spinal surgical patients who suffered immediate postoperative neurologic deficits. METHODS: Of 62,038 spinal surgeries with multimodality IONM, 90 patients with new or worsened postoperative neurologic deficits and whose outcomes were reported immediate to the surgery and at discharge were analyzed...

BACKGROUND: Central retinal artery occlusion (CRAO) is an ophthalmological emergency, the retinal analog of a stroke. To date there is no consensus or national guidelines on how this disorder should be managed. As academic neurologists and ophthalmologists treat CRAO frequently, we set out to understand how these clinicians approach patients with CRAO with a national survey. METHODS: We identified university-associated teaching hospitals offering vascular neurology, neuro-ophthalmology and/or retina fellowships in the US and asked the directors of the programs to respond to questions in an open response format to profile the acute management of CRAO at their institution...

Metastatic spinal cord compression (MSCC) is a medical emergency that requires rapid diagnosis and treatment to reduce pain, to preserve neurological functioning, and to prolong survival. The diagnosis of liver cancer is often neglected in the differential diagnosis of MSCC. Treatment is usually palliative and evolution is often fatal. This is a case report of a 28-year-old patient living in Mauritania hospitalized in November 2014 at the neurology department of Fann national teaching hospital in Dakar, for the management of a chronic dorsal spinal cord compression...

BACKGROUND Emerging data have established links between systemic metabolic dysfunction, such as diabetes and metabolic syndrome (MetS), with neurocognitive impairment, including dementia. The common gene signature and the associated signaling pathways of MetS, diabetes, and dementia have not been widely studied. MATERIAL AND METHODS We exploited the translational bioinformatics approach to choose the common gene signatures for both dementia and MetS. For this we employed "DisGeNET discovery platform". RESULTS Gene mining analysis revealed that a total of 173 genes (86 genes common to all three diseases) which comprised a proportion of 43% of the total genes associated with dementia...

BACKGROUND: Neonatal encephalopathy (NE) affects 2-4/1000 live births with outcomes ranging from negligible neurological deficits to severe neuromuscular dysfunction, cerebral palsy and death. Hypoxic ischemic encephalopathy (HIE) is the sub cohort of NE that appears to be driven by intrapartum events. Our objective was to identify antepartum and intrapartum factors associated with the development of neonatal HIE. METHODS: Hospital databases were searched using relevant diagnosis codes to identify infants with neonatal encephalopathy...

Myelin damage is a hallmark of spinal cord injury (SCI) and potassium channel blocker (PCB) is proven effective to restore axonal conduction and regain neurological function. Aiming to improve this therapy beyond the FDA-approved 4-AP, we have developed multiple new PCBs, with 4-AP-3-MeOH being the most potent and effective. The current study evaluated two PCBs, 4-AP-3-MeOH and 4-AP, in parallel in both ex vivo and in vivo rat mechanical SCI models. Specifically, 4-AP-3-MeOH induced significantly greater augmentation of axonal conduction than 4-AP in both acute and chronic injury...

Background Many specialty societies have found that neuroimaging in headache is a low-value intervention for benign presentations. This study describes factors that influence Emergency Room (ER) physicians' adherence to Choosing Wisely (CW) recommendations for low-risk headache patients presenting to Calgary's Emergency Departments (EDs). Emergency medicine has yet to address imaging in headache as a CW topic; however, this study may inform that decision. Methods Data were retrospectively collected for all patients presenting to Calgary EDs with headaches from April 1, 2014 to March 31, 2016...

Importance: The androgen receptor inhibitor enzalutamide prolongs survival in men with metastatic castration-resistant prostate cancer (mCRPC). In controlled clinical studies, 0.5% (10 of 2051) of patients experienced seizure, but patients with a history of or risk factors for seizure were excluded. Men with mCRPC and seizure risk factors have an estimated seizure rate of 2.8 per 100 patient-years without enzalutamide exposure. Objective: To assess seizure incidence in patients with seizure risk factors who were receiving enzalutamide for mCRPC...
