Application of Transcranial Color-coded Duplex Sonography in the Diagnosis and Management of Straight Sinus Thrombosis With Dural Arteriovenous Fistulae: A Case Report
Conclusions:
TCCS could provide reliable data about the feeder and drainage veins of dAVF in our case. The extent of an increase in venous flow velocity may be closely associated with clinical manifestations, which may influence therapy. Moreover, TCCS possesses a unique advantage in terms of evaluating the patency of the stents compared with other neuroimaging techniques. (Source: The Neurologist)

Branch Retinal Vein Occlusion and Venous Abnormalities in CADASIL
Conclusions:
Within CADASIL, the venous circulation undergoes similar pathologic changes as compared with the arterial circulation. The retinal veins of CADASIL exhibit increased venous compliance, vessel wall diameter and wall thickness which may represent a structurally causative factor for retinal venous disease. However, these findings are not isolated to the retina as lower extremity varicose veins have associated with a family pedigree of CADASIL. Although presently it is uncertain whether those with CADASIL should undergo routine retinal screening, neurologists, and ophthalmologists, need to be cognizant of the ...

Magnetic Resonance Vessel Wall Imaging in Central Nervous System Vasculitides: A Case Series
Conclusions:
In these 3 cases, HR-VWI identified distinctive vascular inflammatory changes, which were crucial to guide the etiological workup, positive diagnosis, surveillance neuroimaging, and targeted treatment. HR-VWI is an important diagnostic tool in CNS vasculitides, by providing nuanced information about arterial wall integrity and pathology. (Source: The Neurologist)

Real-time Assessment of Neurology Residents’ Perceptions of Inappropriate Consults
Conclusions:
NRs were more likely to rate consults as inappropriate if they were also perceived as low urgency, strongly influenced by liability concerns, or unnecessary due to belief that the RP could have cared for the patient without the consult. Our findings suggest a discrepancy in how NRs and RPs perceive neurology consult appropriateness, and help to elucidate potential drivers of these perceptions that could be barriers to education and to interdisciplinary care.

Diffusion Tensor Imaging Tractography Detecting Isolated Oculomotor Paralysis Caused by Pituitary Apoplexy
This study aimed to visualize PA-induced oculomotor nerve damage using diffusion tensor imaging (DTI) tractography.
Materials and Methods:
We enrolled 5 patients with PA-induced isolated oculomotor palsy (patient group) and 10 healthy participants (control group); all underwent DTI tractography preoperatively. Fractional anisotropy (FA) and mean diffusion (MD) values of the cisternal portion of the bilateral oculomotor nerve were measured. DTI tractography was repeated after the recovery of oculomotor palsy.
Results:
While no statistical difference was observed in FA and MD values of the bilateral oculomotor ...

Influence of Intraoperative Microelectrode Recording in Deep Brain Stimulation
Background:
There is considerable debate regarding the use of intraoperative microelectrode recording (MER) in deep brain stimulation (DBS).
Objective:
To determine if the use of intraoperative MER impacts the final position of the lead implant in DBS of the subthalamic nucleus (STN) and globus pallidus (GPi) and to evaluate the incidence of complications.
Methods:
The authors conducted a retrospective chart review of all patients who underwent STN and GPi DBS with MER, at the University of Texas Health Science Center in Houston from June 1, 2009 to October 1, 2013 to compare initial and final coordinates...

Acute Flaccid Myelitis in an Adult
Conclusions:
AFM should be included in the differential for the presentation of acute weakness in adults and pediatric patients. As the incidence of AFM continues to rise, awareness of the condition and prompt obtainment of specimens in suspected patients is crucial to aid in the investigation. (Source: The Neurologist)

Acute Ischemic Stroke as a Result of Paradoxical Embolus in a Patient with Renal Cell Carcinoma, Intravenous Tumor Thrombus Extension, and Patent Foramen Ovale
Conclusions:
This is the first reported case of intraoperative paradoxical embolism in the setting of RCC with cavoatrial extension and PFO. The presence of PFO may be a risk factor for severe cerebrovascular complications in the surgical management of RCC with venous involvement. (Source: The Neurologist)

Recurrent Vertebrobasilar Strokes Associated With Acute Posterior Multifocal Placoid Pigment Epitheliopathy (APMPPE)
Conclusions:
This case illustrates the importance of careful evaluation and high clinical suspicion for this entity when dealing with patients with new-onset headache or stroke associated with visual impairment. Proper ophthalmologic evaluation is important so that adequate therapy is established. (Source: The Neurologist)

Acute Seizures in Cerebral Venous Sinus Thrombosis: Risk Factors and Prognosis
Background:
Cerebral venous sinus thrombosis (CVST) often presents with acute seizures, and recurrent seizures may also be seen in the long term in some patients. The purpose of this retrospective study was to investigate the frequency and type of acute seizures and to define the risk factors.
Methods:
Sixty-two patients diagnosed with CVST between September 2007 and October 2018 were retrospectively evaluated for the occurrence of acute seizures. Seizures which developed as a presenting symptom or occurred within 2 weeks of diagnosis were defined as acute seizures. Demographic, clinical, and radiologic characteristic...

Association Between Long-term Functional Outcome and Change in hs-CRP Level in Patients With Acute Ischemic Stroke
Background and Purpose:
Elevated high-sensitivity C-reactive protein (hs-CRP) has been suggested as a risk factor for ischemic stroke. However, the predictive value of hs-CRP for long-term outcomes is poorly defined. Therefore, we conducted this study to evaluate whether change in hs-CRP level plays a role in the prognostic value of long-term functional disability.
Methods:
We studied 263 patients with acute ischemic stroke and 104 healthy controls (67.5±11.26 and 68.17±11.21 y, respectively). hs-CRP was measured on admission and on the seventh day of hospitalization. The patients were classified into 2 groups on ...
