Disentangling prevalence induced biases in medical image decision-making
Cognition. 2021 Apr 2;212:104713. doi: 10.1016/j.cognition.2021.104713. Online ahead of print.ABSTRACTMany important real-world decision tasks involve the detection of rarely occurring targets (e.g., weapons in luggage, potentially cancerous abnormalities in radiographs). Over the past decade, it has been repeatedly demonstrated that extreme prevalence (both high and low) leads to an increase in errors. While this "prevalence effect" is well established, the cognitive and/or perceptual mechanisms responsible for it are not. One reason for this is that the most common tool for analyzing prevalence effects, Signal Detection ...

Medical Adjuvants in the Treatment of Surgically Refractory Arteriovenous Malformations of the Head and Face: Case Report and Review of Literature
Background: Arteriovenous malformations (AVMs) of the brain and face present unique challenges for clinicians. Cerebral AVMs may induce hemorrhage or form aneurysms, while facial AVMs can cause significant disfigurement and pain. Moreover, facial AVMs often draw blood supply from arteries providing critical blood flow to other important structures of the head which may make them impossible to treat curatively. Medical adjuvants may be an important consideration in the management of these patients.Summary: We conducted a systematic review of the literature to identify other instances of molecular target of rapamycin (mTOR) ...

Medical retirement from sport after concussions: A practical guide for a difficult discussion
Purpose of review In patients with a considerable history of sports-related concussion, the decision of when to discontinue participation in sports due to medical concerns including neurologic disorders has potentially life-altering consequences, especially for young athletes, and merits a comprehensive evaluation involving nuanced discussion. Few resources exist to aid the sports medicine provider. Recent findings In this narrative review, we describe 10 prototypical vignettes based upon the authors' collective experience in concussion management and propose an algorithm to help clinicians navigate retirement discussions...

Guidelines of the Polish Medical Society of radiology for the routinely used MRI protocol in patients with multiple sclerosis.
Abstract Magnetic resonance imaging is widely used in diagnosing multiple sclerosis as a basic method for detecting and monitoring the disease. INTRODUCTION: Polish Medical Society of Radiology presents the second version of the recommendations for the routinely conducted MRI in multiple sclerosis, which include new data and practical remarks for radiographers and radiologists. The recommended protocol aims to improve the imaging procedure and, most importantly, to standardize conducting MRI scans in all MRI departments. This is crucial for monitoring the patients with MS, which directly contributes to essential c...

< b > < i > ACTA2 < /i > < /b > Cerebral Arteriopathy: Not Just a Puff of Smoke
Background: Missense mutations in the gene that codes for smooth muscle actin,ACTA2, cause diffuse smooth muscle dysfunction and a distinct cerebral arteriopathy collectively known as multisystemic smooth muscle dysfunction syndrome (MSMDS). Until recently,ACTA2 cerebral arteriopathy was considered to be a variant of moyamoya disease. However, recent basic science and clinical data have demonstrated that the cerebral arteriopathy caused by mutantACTA2 exhibits genetic loci, histopathology, neurological sequelae, and radiographic findings unique from moyamoya disease. We conducted a literature review to provide insight into...

Magnetic Resonance Imaging and Electroencephalograhic Characteristics in Two Cases of Fatal Eastern Equine Encephalitis (EEE) (P4.317)
CONCLUSIONS:The consistency of the distinctive MR and EEG findings in the two cases we report suggests a pattern which may be pathognomonic for EEE in the appropriate clinical and epidemiological context. These findings could aid in earlier recognition. The pathophysiology for selective viral tropism of EEE to particular brain regions remains unknown but is an area for future research. Study Supported by:None. No funding obtained. Disclosure: Dr. Babi has nothing to disclose. Dr. Applebee has received personal compensation for activities with the DER-401 Publications Steering Committee. Dr. Applebee has received re...

Manifestations of an Uncommon Pontine Insult, Eight-and-a-Half Syndrome (P1.029)
CONCLUSIONS: EHS involves a specific constellation of clinical findings which include OHS and LMN facial palsy, all ipsilateral to the side of the lesion at the level of the pons. On the basis of our review, true EHS is a very rare manifestation. EHS variants, while still unique, are more common.Disclosure: Dr. mannel has nothing to disclose. Dr. Saada has nothing to disclose.

Enterobacter Cloacae Endocarditis Presenting as an Ischemic Stroke (P2.279)
CONCLUSIONS: This is the first case which demonstrates that ischemic stroke can be the presenting clinical event of E. cloacae endocarditis. Clinicians who provide acute care to patients with stroke should be aware of this rare cause of embolic brain infarction. Our case shows that early diagnosis of E. cloacae endocarditis and appropriate medical management can promote full neurological recovery in these patients.

A rare complication in a common setting: Ondansetron-related hemorrhagic reversible posterior leukoencephalopathy syndrome (PRES) following gastric bypass (P2.285)
CONCLUSION: This case highlights a very rare neurological complication of Ondansetron, a commonly used medication. To the best of our knowledge, only 8 cases of Ondansetron-related PRES have been reported to the FDA between January 2004 and October 2012 and none have been previously published in the literature. We postulate that a cerebral dysautoregulation mechanism related to 5-HT3 antagonism led to a cerebral endothelial vasculature dysfunction (angiopathy) which culminated onto PRES. This is supported by the fact of development of PRES despite stable blood pressure and subsequent elevated ICP with otherwise stable imag...

Vascular Territories of Ischemic Stroke in Associated Takotsubo Cardiomyopathy (P1.221)
Conclusions: TC is a reversible cardiomyopathy that has an association with ischemic stroke. This condition can notably be both the cause and effect of stroke. Ischemic stroke of the left middle cerebral artery appears to be the most prevalent. In female patients suffering from middle cerebral artery distribution ischemic stroke and cardiac dysfunction, TC should be considered.Disclosure: Dr. Zia has nothing to disclose. Dr. Silliman has received research support from Genzyme Corporation, Biogen Idec, and Novartis.

Vertigo and Dizziness in Anterior Circulation Cerebrovascular Disease: A Systematic Review (P3.092)
CONCLUSIONS: Vertigo and dizziness are not rare manifestations of carotid territory ischemia, particularly in the temporo-parietal regions. Although dizziness is generally more prevalent in women, anterior circulation stroke causing dizziness appears to be more prevalent in men. Clinicians should carefully consider a search for anterior circulation vascular disease in patients presenting with vestibular symptoms.Disclosure: Dr. Zhou has nothing to disclose.

Predicting Progressive Gangliogliomas: Early Identification Of Those At Risk In A Sample Of 156 Consecutive Patients Treated At The Barrow Neurological Institute (S22.004)
Conclusions: Age predicts survival in adults, not children. Tumor location and MR enhancement are not prognostic. Risk of malignant transformation is related to glial features. Continuing immunohistochemical analysis includes MIB-1/Ki-67, CD34, MGMT and IDH1, as well as 1p19q deletion status for oligodendroglial or mixed features.Disclosure: Dr. Zieman has nothing to disclose.
