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...

REVIEW
Hans-Eckhardt Schaefer
The present study is focused on a review of the current state of investigating music-evoked emotions experimentally, theoretically and with respect to their therapeutic potentials. After a concise historical overview and a schematic of the hearing mechanisms, experimental studies on music listeners and on music performers are discussed, starting with the presentation of characteristic musical stimuli and the basic features of tomographic imaging of emotional activation in the brain, such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET), which offer high spatial resolution in the millimeter range...

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...

Reduction of delay between onset and hospital arrival and adequate pre-hospital care of persons with acute stroke are important for improving chances of a favorable outcome. The objective is to recommend evidence-based practices for the management of patients with suspected stroke in the pre-hospital setting. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology was used to define the key clinical questions. An expert panel then reviewed the literature, established the quality of the evidence, and made recommendations...

BACKGROUND: Threshold concepts (TCs) are defined as ideas within a discipline that are often conceptually difficult ("troublesome"), but when learned, transform a learner's understanding. Electroencephalography (EEG) has been recognized as a conceptually difficult field in neurology, and a study of threshold concepts in EEG may provide insights into how it is taught and learned. METHODS: Semi-structured interviews were performed with 12 EEG experts in the US and Canada...

Several African arboviruses have emerged over the past decade in new regions where they caused major outbreaks in humans and/or animals including West Nile virus, Chikungunya virus and Zika virus. This raise questions regarding the importance of less known zoonotic arboviruses in local epidemics in Africa and their potential to emerge internationally. Syndromic surveillance in animals may serve as an early warning system to detect zoonotic arbovirus outbreaks. Rift Valley fever and Wesselsbronvirus are for example associated with abortion storms in livestock while West Nile-virus, Shuni virus and Middelburg virus causes neurological disease outbreaks in horses and other animals...

Horner's Syndrome (HS) is a neurological syndrome characterised by the triad incomplete pupillary miosis, palpebral ptosis and facial anhidrosis, due to a lesion of the oculosympathetic pathway, formed of three neurons from the hipothalamus to the eye. Identifying its cause is a diagnostic challenge since in spite of its apparent lack of clinical importance, HS can be the first or only manifestation of a serious, or even potentially mortal disorder. We present the case of a 19-year-old male patient with a history of nonspecific ocular pains of two months evolution...

The recent outbreak of Zika virus (ZIKV), a re-emerging flavivirus, and its associated neurological disorders, such as Guillain-Barré (GB) syndrome and microcephaly, have generated an urgent need for developing effective ZIKV vaccines and therapeutic agents. Here, we used human endothelial cells and astrocytes, both of which represent key cell types for ZIKV infection, to identify potential inhibitors for ZIKV replication. Because several pathways, including AMP-activated protein kinase (AMPK), protein kinase A (PKA), and mitogen-activated protein kinase (MAPK) signaling pathways, have been reported to play important roles in flavivirus replication, we tested inhibitors or agonists of these pathways for their effects on ZIKV replication...

Acid-sensing ion channel 1a (ASIC1a) is the key subunit that determines acid-activated currents in neurons. ASIC1a is important for neural plasticity, learning, and for multiple neurological diseases, including stroke, multiple sclerosis, and traumatic injuries. These findings underline the importance for better defining mechanisms that regulate ASIC1a expression. During the past decade, microRNA has emerged as one important group of regulatory molecules in controlling protein expression. However, little is known about whether microRNA regulates ASIC1a...

Cognitive deficits are frequently observed in multiple sclerosis (MS), mainly involving processing speed and episodic memory. Both demyelination and gray matter atrophy can contribute to cognitive deficits in MS. In recent years, neuroinflammation is emerging as a new factor influencing clinical course in MS. Inflammatory cytokines induce synaptic dysfunction in MS. Synaptic plasticity occurring within hippocampal structures is considered as one of the basic physiological mechanisms of learning and memory. In experimental models of MS, hippocampal plasticity is profoundly altered by proinflammatory cytokines...

A previously healthy 16-year-old girl presented to the emergency department with 1 week of severe, diffuse abdominal pain and constipation, as well as several episodes of nonbloody, nonbilious emesis. Her symptoms began several days after she decreased her caloric intake in an attempt to lose weight. She had been drinking 48 to 60 oz of water per day for several days before admission in an attempt to ameliorate her constipation. She also admits to drinking alcohol the night before her pain began. She had visited several other emergency departments before her presentation to our hospital, and she had been sent home on a bowel regimen without amelioration of her symptoms...

While there has been some research into Francoist psychiatry, much work still needs to be done on the reorganization of the mental health profession within the new state. Held in Barcelona on 12, 13 and 14th January 1942, the National Neurology and Psychiatry Conference undoubtedly played a major role in the attempt to overthrow the dominant ideas in the field of Spanish psychiatry and displace its most influential figures. This article seeks to analyse the Conference's main organizational features and examine its most significant content, with the aim of evaluating its strategic importance in the context of both the psychiatrists' professional and scientific interests and their ideological and political concerns...
