COVID-19 Associated With Encephalitis: Case Report and Review of Literature.

INTRODUCTION: Neurological problems may be part of severe and early course of coronavirus disease 2019 (COVID-19). COVID-19 associated encephalitis as an evident etiology of altered consciousness has been rarely reported in the literature. CASE REPORT: A case of 66-year-old female presented with classic COVID-19 symptoms and associated diabetic ketoacidosis. Although diabetic ketoacidosis was managed, the patient had persistent impaired level of consciousness with recurrent attacks of left focal fits because of COVID-19-associated encephalitis. However, the patient has markedly improved after recovering from COVID-19. CONCLUSION: Neurologists should be involved in the evaluation and management of COVID-19 patients who present with associated neurological problems.

Magnet and receiver-stimulator displacement after cochlear implantation: Clinical characters and management approaches.

OBJECTIVES: To systematically review the occurrence of magnet or receiver/stimulator displacement following cochlear implant (CI) placement complication and evaluate the existing literature on this topic. METHODS: A systematic literature search was conducted using PubMed, Scopus, Web of Science, Virtual Health Library (VHL), and Cochrane Library. Original studies reporting cases of magnet or receiver-stimulator migration occurring as a complication after CI placement were included. The quality of the included studies was evaluated using the National Institutes of Health Quality Assessment Tool for observational studies and CARE checklist for case studies. RESULTS: A total of 36 studies, including 6469 patients, were included. Magnet migration was reported in 82 (1.3%) patients, while receiver/stimulator was reported in 4 (0.1%) cases. The cause of magnet migration was identified in 78 cases; MRI-induced movement was the most frequently reported cause (n=43, 55.1%), followed by head trauma (n=25, 32.1%). A total of 20 studies involving 35 patients with magnet migration performed skull radiography to diagnose magnet migration. Revision/exploratory surgery with surgical repositioning or replacement was the most frequent management procedure (n=46). CONCLUSIONS: Further research on magnet pocket design and standard protocols for MRI in CI users is needed. Early diagnosis of magnet migration and instant referral to specialized CI centers is necessary for proper management and prevention of major complications. PROSPERO REG. NO. CRD: 42020204514.

First case of focal epilepsy associated with SARS-coronavirus-2.

A healthy patient presented to Klinikum Altmühlfranken Weißenburg Hospital, Germany, with two morning attacks of painful muscle spasm in the left upper and lower limbs, without altered consciousness. Full examinations, radiological imaging, electroencephalography, lumbar puncture, and autoimmune profile were either normal or not consistent with patient's complaint. Subsequent epileptic episodes were observed on admission day and the following days; thus, the patient was diagnosed with focal epilepsy. The patient started to develop a fever and severe cough on day 4, and SARS-coronavirus-2 was confirmed through a nasopharyngeal swap. She received anticonvulsants and symptomatic treatments and completely recovered. This report emphasizes the potential nervous system involvement in severe acute respiratory syndrome-coronavirus-2 pathogenesis.
