A case with prolonged headache after COVID-19 vaccination and later developed Bell's palsy.

PURPOSE: During COVID-19 pandemic, the authorization of emergent usage of new vaccine has raised suspicions and doubts about potential adverse events related to vaccination. Among the reported adverse events related to ChAdOx1/nCoV-19 vaccine, facial paralysis did not have an incident rate higher than natural occurrence like mRNA vaccines. However, temporal association between vaccination and facial palsy have been documented in several studies. Here, we report a case of an otherwise healthy 23-year-old Taiwanese female who experienced prolonged headache since the second day postvaccination and developed facial palsy on the tenth day. CASE REPORT: A 23-year-old Taiwanese female who was previously healthy experienced intermittent right side throbbing headache, general malaise, myalgia and fever. Headache, transient ear pain and right scalp numbness developed in the next few days but quickly resolved. On day ten after vaccination, signs of facial palsy on the right side of her face was noticed. The results of brain Magnetic Resonance Imaging (MRI) with contrast displayed no abnormality. Facial stimulation and blink reflex tests were compatible with right facial neuropathy. CONCLUSION: Reactivation of latent herpes virus has been suggested as one of the possible mechanisms underlying the phenomenon, but the causal pathophysiology related to the symptom needs further validation. Moreover, in the event of facial palsy post-vaccination, alternative diagnoses such as Guillain-Barre syndrome (GBS), Ramsey-Hunt syndrome, Lyme disease, trauma, central nervous system infection (CNS) infection, or stroke should also be considered.

Transient Bell's palsy following Covid-19 vaccination.

Bell's palsy is described as an acute, unilateral mononeuropathy of the facial nerve resulting in partial or complete paralysis of the face with no identifiable cause. Although facial palsy is often idiopathic, its development soon after the BB-152 Covid vaccine is exceedingly rare. We report a patient with transient acute-onset unilateral infranuclear facial palsy following vaccination, after an exhaustive work-up for other common causes was negative. With no detectable aetiology the likelihood of an association of the Covid-19 vaccine and Bell's palsy remains.

Facial Palsy in COVID-19 Patient: A Case Report.

Facial paralysis is one of the common problems leading to facial deformation. COVID-19 virus rarely has been shown to be associated with facial palsy. Here we present a case of a 60-year-old woman who presented with features of left lower motor facial palsy signs along with common features suggestive of COVID-19 infection. Brain imaging did not reveal any pertinent pathology but her polymerase chain reaction for COVID-19 was positive. This case highlights the fact that acute COVID-19 infection can be considered a cause of motor neuron facial palsy in the ongoing pandemic of COVID-19. Cases with neurological features suggestive of facial palsy therefore should be suspected of acute COVID-19 infection based on other pertinent findings of COVID-19 infection and thus polymerase chain reaction testing should be done. Keywords: case reports; COVID-19; facial palsy.

Hypoglossal nerve palsy after SARS-CoV-2 vaccination - report of two cases.

BACKGROUND: SARS-CoV-2 vaccination is associated with an increased risk for Bell's palsy and some other neurological disorders assumed to be of autoimmune origin. While facial nerve palsy is frequent and usually idiopathic, hypoglossal nerve palsy is rare, and a specific cause is almost always found. We firstly report two patients who developed isolated hypoglossal nerve palsy shortly after SARS-CoV-2 vaccination. CASE PRESENTATION: Two otherwise healthy patients, a 49-year-old man and a 39-year-old woman, developed unilateral hypoglossal nerve palsy 10 and 7 days after the second SARS-CoV-2-vaccination (AstraZeneca and BioNTech/Pfizer), respectively. In both subjects, needle electromyography showed denervation and rarefication of motor units. CT, MRI, examination of blood and CSF as well as ENT exam were unremarkable. In both subjects symptoms gradually improved. CONCLUSION: Due to close temporal relationship, the absence of other etiologies, and spontaneous improvement we suspect the vaccination as the cause for hypoglossal nerve palsy in both patients. This is further supported by the rarity of isolated hypoglossal nerve palsies, especially in idiopathic cases. We suggest the addition of hypoglossal nerve palsy to the list of neurological injuries potentially caused by SARS-CoV-2 vaccination.

New-onset Bell's palsy after neuroinvasive West Nile virus.

In this case report, a patient was diagnosed with new-onset Bell's palsy 3 weeks after the onset of neuroinvasive West Nile virus. This was the second case report of West Nile virus-associated Bell's palsy, highlighting the need to monitor these patients for peripheral neuropathies. This case report is also intended to raise awareness about the prevalence of West Nile virus in the USA.

A case of facial nerve palsy in a pediatric patient associated with Covid-19.

BACKGROUND: Pediatric facial nerve palsy is acute and mostly idiopathic; other causes are post-infectious forms. CASE PRESENTATION: We describe a rare case of facial nerve palsy associated with COVID-19 in a 5-year-old boy. The diagnosis of post-infectious COVID-19-related facial paralysis was made by serology positivity for a previous infection (IgG positive, IgM and IgA weakly positive), in the presence of a negative molecular nasopharyngeal swab and in the absence of other etiologies. Early treatment with steroids (1 mg/day for 7 days followed by tapering) and supportive care solved the problem. CONCLUSION: In a child with facial paralysis, COVID-19 must be considered as the cause and both nasopharyngeal swab and serology must be performed.

Surge of Bell's Palsy in the era of COVID-19: Systematic review.

BACKGROUND AND PURPOSE: With the progression of coronavirus infectious disease 2019 (COVID-19), various neurological manifestations have been noticed in infected patients, and Bell's Palsy (BP) is one of the peripheral neuropathies among those. BP has been associated with various other viral agents. Its evidence in patients with COVID-19 signifies the possibility of association between BP and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This research was undertaken to evaluate the number of published cases of BP as the only major neurological manifestation in patients with COVID-19 from March 2020 to December 2021 and to investigate the association of SARS-CoV-2 and BP. METHODS: A systematic review of the published English literature was performed using an electronic search in the PubMed/Medline, Scopus, Research Gate, Research Square, and Google Scholar databases, using keywords such as "COVID-19" OR/AND "SARS-CoV-2" OR/AND "Bell's palsy" OR/AND "facial nerve palsy" OR/AND "neurological" OR/AND "manifestation". RESULTS: The search strategy revealed 32 relevant publications with a total of 46 patients. BP was the initial manifestation in 37% of cases, and in 63% of cases it developed after COVID-19 symptoms; 71.7% of cases showed complete recovery, and 21.7% showed only partial relief from BP. CONCLUSIONS: Although the number of documented cases in this research is low, evidence of BP as the only major neurological manifestation in patients with COVID-19 signifies an important clinical finding and the possibility of another viral etiology of BP. More evidence is needed to establish the exact correlation between these two entities.

Can isolated sudden sensorineural hearing loss (SSNHL) and idiopathic acute facial paralysis (Bell's palsy) be symptoms of COVID-19?

OBJECTIVES: The symptoms of COVID-19 at the time of presentation mainly include fever, cough, respiratory distress and myalgia. On the other hand, as neurological symptoms, disruption of taste and smell and cerebrovascular pathologies are well-known, whereas other neurological symptoms and signs are being newly recognized. Sudden-onset sensorineural hearing loss (SSNHL) and idiopathic acute facial paralysis (Bell's palsy) are otologic emergencies that are frequently encountered by otorhinolaryngology specialists. Although there are many articles describing SSNHL and Bell's palsy in the literature, the literature describing their relationship to COVID-19 is limited. In our study, we aimed to present the neuro-otologic relationship of SSNHL and Bell's palsy with COVID-19. MATERIAL AND METHODS: The pretreatment real-time oronasopharyngeal PCR tests, COVID-19 symptomatology and COVID-19 infection statuses of patients who presented to our clinic with isolated SSNHL and Bell's palsy between April 2020 and April 2021 were questioned, and the data of the patients were collected. Throughout their treatment, the patients were followed-up in terms of COVID-19 infection. This is a prospective study. Moreover, to observe the change in the incidence, the data of patients visiting between January 2019 and January 2020 were also collected. The data of the patients were statistically analyzed using SPSS. RESULTS: The study included a total of 177 patients. The SSNHL group consisted of 91 patients, and the Bell's palsy group consisted of 86 patients. Neither group showed a statistically significant difference in comparison to the year without the pandemic in terms of the patient numbers (incidence), sex, age, morbidity, response to treatment or social habits. There was a statistically significant difference in age only in the Bell's palsy group, but this difference was not medically significant. CONCLUSION: As a result of our study, we did not observe a relationship between COVID-19 and cases of SSNHL and Bell's palsy. It is recommended to apply standard otologic treatment to isolated SSNHL and Bell's palsy patients whose association with COVID-19 is not determined.

Does the SARS-CoV-2 pandemic really increase the frequency of peripheral facial palsy?

PURPOSE: Publications about increased number of peripheral facial paralysis in the COVID-19 pandemic emerged in the literature. However, these studies comprised of an estimate rather than a broad analysis of exact numbers. In this study, we planned to investigate whether the pandemic really resulted in an increase in facial paralysis cases admitted to the hospital by evaluating the cases who applied to our hospital due to facial paralysis in the COVID-19 pandemic year and in the previous 4 years. MATERIALS AND METHODS: Patients who applied to our hospital due to facial paralysis between March 2016-February 2017 (Group 1), between March 2017-February 2018 (Group 2), between March 2018-February 2019 (Group 3), between March 2019-February 2020 (Group 4), and between March 2020-February 2021 (Group 5) were investigated and detailed data were noted. RESULTS: 156, 164, 149, 172 and 157 patients were admitted to the hospital due to peripheral facial paralysis in Group 1, 2, 3, 4, and 5, respectively. Of these patients, 155, 164, 145, 169, and 153 were Bell's palsy, respectively. SARS-CoV-2 RT-PCR test was positive in only 2 of the 153 patients who were diagnosed in the year of the pandemic. CONCLUSIONS: This study showed that the number of peripheral facial paralysis detected during the COVID-19 pandemic was similar to previous years. Very few number of positive SARS-CoV-2 RT-PCR test results may have been found incidentally in Bell's palsy patients. Theses stating that SARS-CoV-2 causes peripheral facial paralysis should be supported by laboratory studies and postmortem research.

Concomitant Guillain-Barre syndrome with COVID-19: a case report.

BACKGROUND: During the Coronavirus disease 2019 (COVID-19) pandemic, different neurological manifestations have been observed. However, only a few cases of Guillain-Barre syndrome (GBS) and COVID-19 have been reported. Therefore, the aim of this study is to investigate a case of concomitant GBS with COVID-19 in Colombia. CASE PRESENTATION: A 39-year-old woman was admitted to a teaching hospital in Barranquilla, Colombia with a history of progressive general weakness with lower limb dominance. Previous symptoms such as ageusia, anosmia and intense headache were reported. Upon admission, facial diplegia, quadriparesis with lower extremity predominance and Medical Research Council muscular strength of 2/5 in the lower limbs and 4/5 in the upper limbs were reported. During clinical evolution, due to general areflexia, hypertensive emergency and progressive diaphragmatic weakness, the patient was admitted to an intensive care unit. The cerebrospinal fluid analysis showed protein-cytological dissociation and the GBS diagnosis was confirmed via a nerve conduction and electromyography test. With regard to the symptoms before hospitalisation, SARS-CoV-2 diagnostic testing was performed with positive results in the second test. The patient was managed with supportive care and was discharged after 20 days of hospitalization with clinical improvement. CONCLUSIONS: Only a few cases of COVID-19 with GBS have been reported. Different subtypes have been previously identified, such as Miller-Fisher syndrome and dysautonomic GBS with SARS-CoV-2 infection. This study investigated the first confirmed case of COVID-19 with concomitant GBS in Colombia. In patients with GBS, several viral and bacterial pathogens have been found in case-control studies but the factors that induce the immune-mediated destruction of the nerve tissues have not been determined. Further studies are needed to determine the possible association between COVID-19 exposure and GBS.

A 44-Year-Old Hispanic Man with Loss of Taste and Bilateral Facial Weakness Diagnosed with Guillain-Barré Syndrome and Bell's Palsy Associated with SARS-CoV-2 Infection Treated with Intravenous Immunoglobulin.

BACKGROUND This case report is of a patient who presented with loss of taste and facial weakness and was diagnosed with Guillain-Barre syndrome (GBS) and Bell's palsy, associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. GBS is a neurological emergency defined as acute inflammatory demyelinating polyneuropathy. The patient responded to intravenous immunoglobulin (IVIG) treatment. CASE REPORT We present the case of a 44-year-old Hispanic man who came for evaluation of bilateral facial weakness and lack of taste sensation. He had lower motor neuron facial weakness. His head computed tomography and brain magnetic resonance imaging scans did not show any pathological abnormalities. He tested positive for SARS-CoV-2 by a nasopharyngeal swab reverse transcription polymerase chain reaction (RT-PCR) test. Cerebrospinal fluid (CSF) analysis via lumbar puncture revealed elevated protein levels, no leukocytes, and a negative Gram stain. The CSF RT-PCR test for SARS-CoV-2 was negative. PCR tests of the CSF for other viral infections were negative. A diagnosis of GBS was made, and he was treated successfully with IVIG. After the fourth dose of IVIG, the patient was able to close his eyes, frown, show his teeth, and smile. CONCLUSIONS Our case is rare because the patient did not present with lower extremity weakness, but only with bilateral Bell's palsy. Physicians should be aware of GBS because it is a neurological emergency for which COVID-19 can be a risk factor. Early diagnosis and treatment of GBS can prevent neurological disability.

Bell's palsy in a pediatric patient with hyper IgM syndrome and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Bell's palsy is an acute facial paralysis with known association to viral infections. We describe a medically complex 6-year-old male with hyper IgM syndrome who presented with unilateral facial droop and positive SARS-CoV-2 RT-PCR. This is the first reported pediatric case of Bell's palsy in the setting of SARS-CoV-2 infection.
