Comparative StudyA Comparison of Probabilistic and Deterministic Match Strategies for Linking Prehospital and in-Hospital Stroke Registry Data.
Understanding and improving EMS stroke care requires linking data from both the prehospital and hospital settings. In the US, such data is collected in separate de-identified registries that cannot be directly linked due to lack of a common, unique patient identifier. In the absence of unique patient identifiers two common approaches to linking databases are deterministic matching, which uses combinations of non-unique matching variables to define matches, and probabilistic matching, which generates estimates of match probability based on the degree of similarity between records. This analysis seeks to compare these two approaches for matching EMS and stroke registry data. ⋯ Probabilistic matching resulted in higher match rates and a more representative sample of EMS transported strokes, suggesting it may be superior in assessing EMS stroke care compared to a deterministic approach.

Multicenter Study Comparative Study Observational StudyClinical Characteristics and Clinical Course of Body Lateropulsion in 47 Patients with Brainstem Infarctions.
In patients with lower lateral medullary infarction (LMI) located under the vestibular nucleus, proprioceptive impairment due to dorsal spinocerebellar tract (DSCT) is considered a pathological condition for body lateropulsion. In patients with brainstem infarction located at or above the level of the vestibular nucleus, other pathways, such as the crossed vestibulothalamic tract (CVTT), are considered responsible. ⋯ Lower LMI primarily affected body lateropulsion in gait. DSCT damage could affect ipsilateral hip joint or leg coordination, causing body lateropulsion in dynamic situation.

Review Case ReportsA Rare Clinical Antity; Pure Gerstmann Syndrome.
Gerstmann syndrome is defined as a tetrad including agraphia, acalculia, finger agnosia, and right-left disorientation. In the case studies presented in the literature, it has been reported that Gerstmann syndrome usually appears as an incomplete tetrad of symptoms or accompanied by cognitive deficits including aphasia, alexia, apraxia and some perceptual disorders. ⋯ In addition to the symptoms mentioned above, the patient had alexia and anomic aphasia as well. We discussed the clinic appearance and reviewed the current literature.

Observational StudyClinician's Perception of Practice Changes for Stroke During the COVID-19 Pandemic.
Approach to acute cerebrovascular disease management has evolved in the past few months to accommodate the rising needs of the 2019 novel coronavirus (COVID-19) pandemic. In this study, we investigated the changes in practices and policies related to stroke care through an online survey. ⋯ Our study highlights a change in practices and polices related to acute stroke management in response to COVID-19 which are variable among institutions. There is also a reported reduction in stroke volume across hospitals. Amongst these changes, updates in hospital transport guidelines and practices related to IV-tPA and MT may affect the perceived care and outcome of acute stroke patients.
