ABSTRACT
Originating from Wuhan, China, COVID-19 has rapidly spread worldwide. Neurological manifestations are more commonly associated with severe COVID-19 infection. Guillain-Barré syndrome (GBS) is a rare immune-mediated postinfectious neuropathy. It has been reported as a possible rare complication of COVID-19. We report a case of GBS associated with COVID-19 in the UK.

OBJECTIVE: Hyperventilation (HV) is one of the main and basic activation methods during ambulatory electroencephalogram (EEG), unless medical reasons contraindicate it. During the COVID-19 pandemic, with the high risk of human-to-human infection, local guidelines and recommendations have been developed that suggest not to perform the HV maneuver routinely. Our objective was to characterize patients who present positive HV in an epilepsy center. METHODS: We analyzed retrospectively all the ambulatory EEGs performed during one year in our specialized ambulatory child and adolescent epilepsy center, and describe patients with positive maneuver. RESULTS: A total of 305 EEGs were performed. Patients under 3 years and 11 months were excluded as well as all patients that did not fill up the criteria for epilepsy diagnosis. From the 252 EEGs that were included in the study, 194 EEGs (77%) were classified as abnormal and 58 (23%) as normal. From these same 252 EEGs, 150 EEG finished correctly the HV maneuver. Physiological slowing response was found in 54 EEGs (36%), no changes (negative) in 83 (55%), and abnormal response (positive) in 13 EEGs (9%). The 13 HV-positive EEGs showed 4 patients with an increase of epileptiform activity, 3 patients experienced an increase of basal preregistered abnormal slowing, and 6 EEGs showed trigger of bilaterally synchronous and symmetric 2-4 Hz spike-and-slow wave discharges and absences. None of these last 6 patients needed more than 3 minutes to elicit the paroxysmal discharge. SIGNIFICANCE: Based on these findings and according with other studies, the low positivity and high specificity of the HV maneuver support the idea that HV could be excluded during the COVID-19 pandemic situation, and also reevaluate whether it could be changed to a complementary maneuver, restricted only for cases where absence epilepsy is suspected. Larger studies will be needed to reaffirm this proposal.

BACKGROUND: Acute neurological sequela in patients with COVID-19 infection include acute thromboembolic infarcts related to cytokine storm and post infectious immune activation resulting in a prothrombotic state. Radiologic imaging studies of the sinonasal tract and mastoid cavity in patients with COVID-19 infection are sparse and limited to case series. In this report, we investigate the radiologic involvement of nasal cavity, nasopharynx, paranasal sinuses, and mastoid cavity in patients with SARS-CoV-2 infection who presented with acute neurological symptoms. METHODS: Retrospective review of medical records and neuroradiologic imaging in patients diagnosed with acute COVID-19 infection who presented with acute neurological symptoms to assess radiologic prevalence of sinus and mastoid disease and its correlation to upper respiratory tract symptoms. RESULTS: Of the 55 patients, 23 (42%) had partial sinus opacification, with no evidence for complete sinus opacification. The ethmoid sinus was the most commonly affected (16/55 or 29%). An air fluid level was noted in 6/55 (11%) patients, most commonly in the maxillary sinus. Olfactory recess and mastoid opacification were uncommon. There was no evidence of bony destruction in any of the studies, Cough, nasal congestion, rhinorrhea, and sore throat were not significantly associated with any radiological findings. CONCLUSION: In patients who present with acute neurological symptoms, COVID-19 infection is characterized by limited and mild mucosal disease within the sinuses, nasopharynx and mastoid cavity. LEVEL OF EVIDENCE: 4.

Since 1995, ASET has periodically published updates to recommendations for best practices in infection prevention for Neurodiagnostic technologists. The latest installment was accepted in December 2019 for publication in Volume 60, Issue 1, before we had much knowledge or understanding about the SARS-CoV-2, the virus that causes COVID-19. This Technical Tips article is presented as an addendum to the 2020 update and includes important information about infection prevention measures specific to procedure protocols when working with patients positive or under investigation for a highly infectious disease, and when working with patients in general during the current pandemic. All Neurodiagnostic technologists who have direct patient care are responsible for ensuring the use of best practices to prevent the spread of infection.

BACKGROUND AND PURPOSE: Telephone-based assessment may be a valuable and cost-effective approach to improve monitoring and follow-up assessments in patients and research participants. Telephone-based assessment may be of particular value during times when it is important to reduce in-person contract, such as during the Covid-19 pandemic. The purpose of this study was to investigate concurrent validity of the telephone-based administration of the ABILHAND for the assessment of manual ability in individuals with stroke. METHODS: Using a cross-sectional study design, participants with stroke were invited to answer the ABILHAND questionnaire on 2 randomized occasions, face to face and by telephone, 5 to 7 days apart. The mean difference (MD) between the interviews was calculated (95% confidence interval [95% CI]) to investigate the concurrent validity. Intraclass correlation (ICC) and weighted κ coefficients were used to investigate the agreement between face-to-face and telephone-based administration. RESULTS: One hundred two participants (50 men; mean age = 65 years, SD = 13 years) were included. No significant differences were observed between the mean scores obtained with face-to-face and telephone-based administration of the ABILHAND (MD = -0.06; 95% CI, -0.72 to 0.60). Very high agreement was found between face-to-face and telephone-based administration (ICC = 0.90; 95% CI, 0.85 to 0.93) on the ABILHAND total scores. Most of the individual items had moderate or substantial κ agreement. DISCUSSION AND CONCLUSIONS: Telephone-based administration of the ABILHAND is valid for the assessment of manual ability after stroke. Clinicians and researchers may use the ABILHAND for monitoring manual ability in persons with stroke and/or screening potential research participants.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A318).

The COVID-19 pandemic has had a major impact on clinical practice. Safe standards of practice are essential to protect health care workers while still allowing them to provide good care. The Canadian Society of Clinical Neurophysiologists, the Canadian Association of Electroneurophysiology Technologists, the Association of Electromyography Technologists of Canada, the Board of Registration of Electromyography Technologists of Canada, and the Canadian Board of Registration of Electroencephalograph Technologists have combined to review current published literature about safe practices for neurophysiology laboratories. Herein, we present the results of our review and provide our expert opinion regarding the safe practice of neurophysiology during the COVID-19 pandemic in Canada.
