Summary:
With the versatility of lumbar spine surgery continually expanding, intraoperative electromyography (EMG) has become a common adjunct used to reduce risk of nerve injury and postoperative neurologic deficit. EMG monitoring has been deemed particularly useful in the minimally invasive transforaminal lumbar interbody fusion. A more recent evolution of the minimally invasive transforaminal lumbar interbody fusion entails complete percutaneous access to the disc through Kambin's triangle, followed by a percutaneous lumbar interbody fusion. Given the lack of direct visualization of nervous structures with percutane...

Sharps Injuries Related to Subdermal Needles in the Orbicularis Oris During Intraoperative Neurophysiologic Monitoring
Conclusions:
The placement of subdermal needles in the OO presents a disproportionately high risk of sharps injury. Interventions were performed to attempt to decrease the rate of sharps injuries from needles in OO; the post-intervention increase in events was likely skewed by small sample sizes. The implementation of these changes and the ongoing surveillance of injury cases may be important data to help decrease the number of sharps injuries attributed to IONM needles.

Correlation of Pattern Reversal and Flash Visual Evoked Potential Latencies With Optical Coherence Tomography Measures in Patients With Optic Neuropathy and Patients With Multiple Sclerosis Without Optic Neuropathy
Conclusions:
Patients with ON have delayed VEPs and thinner optical coherence tomography values. Flash visual evoked potentials correlate with pRNFL, indicating axonal pathology. PRVEP correlate with GCIPL, indicating ganglion cell pathology. Abnormal PRVEP with preserved normal f-VEP indicate isolated myelin damage. Abnormalities in both PRVEP and f-VEP indicate myelin and axonal damage in the optic nerve. Combining the results of PRVEP, f-VEP, pRNFL, and GCIPL, one can define the location, type, and extent of the lesion in the macula and optic nerve. (Source: Journal of Clinical Neurophysiology)

Clinical and Polysomnographic Characteristics of Nonobese and Obese Chinese Patients With Obstructive Sleep Apnea
Purpose:
Obesity is a risk factor associated with the onset and exacerbation of obstructive sleep apnea (OSA). However, the majority of OSA patients in Asian populations are nonobese. To date, there have been insufficient large-scale studies of the differences in the clinical and polysomnographic features of obese and nonobese OSA patients in this population, and few studies have sought to identify predictors of OSA severity in affected obese and nonobese patients.
Methods:
We conducted a case-matched retrospective study, including 652 consecutive Chinese OSA patients (326 nonobese and 326 obese) to assess diffe...

Melatonin Versus Chloral Hydrate for Sleep Electroencephalography Recording in Children: A Comparative Study Using Bispectral Index Monitoring Scores and Electroencephalographic Sleep Stages
Purpose:
To compare the effects of chloral hydrate and melatonin on sleep EEG recordings in children by using standard EEG sleep stages and the bispectral index scores (BIS).
Methods:
A total of 86 children were randomly assigned to two groups: (1) melatonin group (n = 43) and (2) chloral hydrate group (n = 43). BIS monitoring scores and sleep EEGs were recorded simultaneously. The effect of two drugs on sleep EEG recording was evaluated with sleep stages of EEG and BIS.
Results:
There was no statistically significant difference between the groups with regard to time to sleep onset and the need for a seco...

Prevalence, Risk Factors, and Impact of Preoperative Seizures in Neonates With Congenital Heart Disease
Conclusions:
In this cohort, preoperative electrographic seizures were common, were all subclinical, and were associated with MRI brain injury and postnatal diagnosis of transposition of the great arteries. The findings motivate further study of the mechanisms of preoperative brain injury, particularly among neonates with a postnatal diagnosis of transposition of the great arteries.

Quantitative Electroencephalography After Pediatric Anterior Circulation Stroke
Conclusions:
After pediatric anterior circulation acute ischemic stroke, reduced spectral edge frequency and alpha and beta power can be observed on injured as compared with noninjured regions. After pediatric anterior circulation hemorrhagic stroke, total power can be negatively associated with arterial blood pressure within injured regions. Larger studies are needed to understand conditions in which QEEG patterns manifest and relate to hemodynamics and brain penumbra. (Source: Journal of Clinical Neurophysiology)

Macroperiodic Oscillations Are Associated With Seizures Following Acquired Brain Injury in Young Children
We describe a phenomenon seen on color density spectral array but not raw EEG associated with seizures and acquired brain injury in pediatric patients.
Methods:
We reviewed EEGs of 541 children admitted to an intensive care unit between October 2015 and August 2018. We identified 38 children (7%) with a periodic pattern on color density spectral array that oscillates every 2 to 5 minutes and was not apparent on the raw EEG tracing, termed macroperiodic oscillations (MOs). Internal validity measures and interrater agreement were assessed. We compared demographic and clinical data between those with and without MOs.

Tracking Multisite Seizure Propagation Using Ictal High-Gamma Activity
Conclusions:
Ictal HGA may serve as a useful adjunctive biomarker to distinguish contiguous seizure spread from propagation to remote seizure sites. High-gamma sites were found to cluster in stereotyped seizure hubs rather than being broadly distributed. Multiple hubs were common even in cases that were considered unifocal.

Neurophysiological Findings in Critical COVID-19 Patients With Peripheral Nervous System Manifestations
Conclusions:
In critical coronavirus disease 2019 patients with neuromuscular complaints, neurophysiological examination provides an accurate diagnosis—useful to select treatment measures and establish the prognosis of recovery. Neurophysiological findings are similar to those described for critical illness neuromuscular disease, with myopathy being the most frequent diagnosis. (Source: Journal of Clinical Neurophysiology)

COVID-19 Continuous-EEG Case Series: A Descriptive Study
Conclusions:
In this observational case series of 16 patients with COVID-19 who were monitored with continuous video-EEG, most patients experienced a nonspecific encephalopathy. Clinical seizures and electrographic status epilepticus were the second most commonly observed neurological problem. (Source: Journal of Clinical Neurophysiology)

Impact of the COVID-19 Pandemic on Continuous EEG Utilization
Conclusions:
There has been a widespread reduction in cEEG volume during the pandemic. Given the anticipated duration of the pandemic and the importance of cEEG in managing hospitalized patients, methods to optimize use need to be prioritized to provide optimal care. Because the survey provides a cross-sectional assessment, follow-up studies can determine the long-term impact of the pandemic on cEEG utilization. (Source: Journal of Clinical Neurophysiology)
