Disorders of consciousness (DOC) are a clinically significant and personally tragic class of health impairments posing significant diagnostic challenge. Uncertainties in the understanding of consciousness and the inability of patients to communicate their physical status pose obstacles to the resolution of states with overlapping manifestations.
When patients present to emergency department (ED) with acute focal neurological deficit sometimes it is hard to make decision about IV thrombolysis. In such situation a neurologist needs to make a judgement call about it. According to some studies IV thrombolysis is safe for patients with stroke mimics, but small possibility of hemorrhage still exists. Furthermore, unnecessary IV thrombolysis in stroke mimics significantly increases cost of care. We aimed to determine if presence of headache in patients with focal neurological deficit during stroke alert makes a difference in neurologist's decision about IV thrombolysis.
The systematic position of the lamprey, as one of only two extant jawless vertebrate, makes its ear of particular interest from evolutionary, developmental and physiological standpoints. Studying the ear of the lamprey could give us insight into the morphology of the archetype/prototype ear of lamprey/jawed vertebrates' ancestor. Moreover, the seemingly simple neural circuits that relay information between the ear and brain to control gaze and posture could help us better understand the complex circuitry underlying vestibuloocular and vestibulospinal reflexes in a more derived vertebrates.
We tried to clarify the results of elderly meningioma based on the literature review. We searched the PubMed database using the terms "meningioma," "elderly," and "surgery" for English-language clinical studies and collected related papers published from 2003 to 2018. Twenty-four papers were reviewed and a total number of cases was 10,009. The mean rate of tumor size over 40mm in diameter was 62.8%, 38.9% of location was skull base related, and 30.7% of the cases was asymptomatic cases.
Objectives: With the emergence of an exponential growth in the number of scientific journals, it becomes difficult to ascertain those which are reputable from those which are of the so-called ‘predatory’ type. The current study aimed to investigate whether the brain morphology and neuropsychological profiles differ between the editors of these two types of journals.
