Guillain–Barré Syndrome as a Neurological Complication of COVID-19 Infection: A Case Series and Review of the Literature

Background: The novel coronavirus (COVID-19) is a global pandemic. Although the main clinical manifestations of the COVID-19 infection has confined to the respiratory system, there is some evidence suggesting the neuro-invasive potential of the COVID-19. There are limited reports of Guillain–Barré syndrome (GBS) as a peripheral nervous system complication of COVID-19 infection.Methods and results: We described four patients with COVID-19 infection who developed acute polyneuropathy with a final diagnosis of Guillain–Barré syndrome.Conclusion: COVID-19 may have the potential to invade the peripheral nervous system. GBS, as one of the critical neurological complications of COVID-19, could be considered as a post-infectious event

Bilateral Third Nerve Paralysis as a Manifestation of Guillain–Barré Syndrome

Gullian–Barré syndrome (GBS) is an acute autoimmune polyradiculoneuropathy with many variants and distinct presentations. Although cranial neuropathy is a common feature in GBS, third nerve palsy is a rare presentation. Herein, we describe a case of GBS patient who has presented by acute flaccid quadriparesis coexisting bilateral third nerve palsy. We tried to highlight the importance of other cranial nerve involvement in the natural history of GBS

New Advances in Acute Ischemic Stroke Management: Review Article

Cerebrovascular disease is the second cause of death and the sixth cause of morbidity worldwide, which will rise to fourth place by 2020. The treatment strategies for acute ischemic stroke (AIS) divided into two groups, including intravenous or intra-arterial thrombolysis and mechanical thrombectomy. Regarding growing development in the realm of diagnosis and treatment of stroke through state-of-the-art approaches, including emergent thrombectomy, there are new opportunities for investigation in this area. This is while a rough rate of 85% for strokes is occupied by, and the remained is hemorrhagic. Hence, the present study aimed to review recent advances in AIS with a focus on emergent thrombectomy. Here, we first provided the relevant history, and then the recent advances were discussed. The library data collection method was employed so that such databases as Web of Science, PubMed, and Science Direct used for data extraction. The evidence confirms the importance of emergent thrombectomy as all believe the famous statement “time is the brain.” However, further investigations are required to find more strong evidence accordingly

The Anxiety Disorder Among the Healthcare Providers During The COVID-19 Infection Pandemic: A Systematic Review

Background: The outbreak of the novel coronavirus disease (COVID-19) imposes a considerable psychological burden on the medical staff working in central hospitals for COVID-19. In this systematic review, we will discuss the prevalence and the risk factors of anxiety disorder among the frontline medical staff dealing with COVID-19 patients.Methods: PubMed, Scopus, Embase, Web of Science data bases were systematically searched from December 01, 2019 to April 30, 2020 for related published articles. In all electronic databases, the following search strategy was implemented and these key words (in the title/abstract) were used: “COVID-19” OR “novel Coronavirus” AND “anxiety” OR “psychology” OR “psychiatry” OR “psychological distress” AND “nurses” or “clinicians”. We included only the cross sectional studies.Results: Through the search strategy, we could identify eight related cross sectional articles about anxiety among the healthcare workers in central hospitals for COVID-19 infection. However, the authors scanned the reference lists of the included studies and identified multiple references. According to our findings, the frontline medical staff are at risk developing anxiety disorder which is mainly mild. Additionally, the female nurses are more susceptible to experience anxiety during the COVID-19 pandemic.Conclusion: Regarding to the outbreak of COVID-19 worldwide and the workload of the frontline medical staff dealing with COVID-19 patients, a particular attention should be given on the mental health of the healthcare provides

Relationship of Opening CSF Pressure and Visual Field Defect in Idiopathic Intracranial Hypertension

Background: Idiopathic intracranial hypertension (IIH) is an increased intracranial pressure with normal cerebrospinal fluid (CSF) characteristic in the absence of identifiable causes. The most important complication of this disorder is visual impairment. So far, no comprehensive study has been done on the relationship between the opening CSF pressure and visual field defect in IIH.Methods: In this study, 35 patients with increased intracranial pressure who fulfilled modified Dandy’s criteria underwent ophthalmologic examination and lumbar puncture. The opening CSF pressure was categorized into mild (25-30), moderate (30-40) and severe (>40). The degree of visual field defect was reported both quantitatively and qualitatively. Eventually, the statistical relationship was established among these variables.Results: The mean opening CSF pressure was 33.71 CmH2o. Twelve patients had minor CSF pressure, whereas in 14 and 9 patients the CSF pressure was respectively moderate and severe. There was not statistically significant relationship between the visual field defect and CSF pressure. The most common patterns of visual field involvement were enlarged blind spot and peripheral restriction.Conclusion: The most important morbidity in IIH is visual impairment. According to the findings, the visual field impairment is not pertinent to CSF pressure. In other words, neither high CSF pressure predicts intense visual defect, nor low CSF pressure indicates minimal visual impairment

Spinocerebellar Atrophy Type-3 with Chiari Malformation in a Young Man: A Case Report

Introduction: Chiari malformations are a group of congenital anomalies which involve the hindbrain and the cervical spinal canal. Case presentation: Here, we describe a patient who presented with acute diplopia and gait unsteadiness which was first deigned with Chiari malformation type-1. However due to progression of the ataxia the full neurologic evaluation was considered which established the diagnosis of spinocerebellar ataxia type 3 (Machado-Joseph-Disease). Conclusion: We aim to highlight the importance of careful examination in order to avoid misdiagnosis of even rare diseases

Propagating Relationship of Cerebral Oximetric Volume and the Clinical Outcome of Recombinant Tissue Plasminogen Activator (r-TPA) Therapy on Acute Cerebral Ischemic Stroke Patients

Introduction: Currently, the most available treatment for acute ischemic stroke (AIS) is thrombolytic therapy with recombinant tissue plasminogen activator (r-TPA). A challenge in r-TPA therapy is the prediction of recovery in each case. Objective: The aim was to find a possible relationship between the cerebral oximetry indexes and the clinical outcome of r-TPA therapy to assess the cerebral oximetry as a non-invasive monitoring agent for therapy. Methods: The inclusion criteria were all patients with AIS who received r-TPA. The neurologic status was evaluated based on the national institutes of health stroke scale (NIHSS) score at arrival, and after a period of 24 hours. In addition, the levels of brain oxygenation in both hemispheres were measured before and continuously over the first 24 hours after r-TPA injection, using an oximetric sensor in the frontal lobes. The clinical success was defined as a 4-point improvement from the baseline NIHSS. Results: Total 44 patients with the mean age of 58.2 ± 2.18 years were enrolled, of whom 68.18% were male. Twenty-eight patients remained clinically unimproved and 16 patients were improved. A significant difference was found in the mean surface area under the brain oximetric curve in the 24 hour, in the affected hemisphere in the improved group, compared to the unimproved group (P = 0.007). There was a significant difference between the mean increase in brain oxygenation within 24 hours in the improved and unimproved groups (P = 0.002). Conclusion: The cerebral oximetry could contribute to predict the likelihood of r-TPA prognosis in patients with AIS

Guillain-Barré Syndrome as a Neurological Complication of Novel COVID-19 Infection: A Case Report and Review of the Literature

INTRODUCTION: The novel coronavirus (COVID-19) is a global pandemic. Although the main clinical manifestation of COVID-19 is respiratory involvement, there is evidence suggesting the neuroinvasive potential of COVID-19. There are limited reports of neurological complications of COVID-19 infection in the literature. Herein, we aim to describe 2 members of a family affected by COVID-19, presenting with ascending paresthesia with the final diagnosis of Guillain-Barré syndrome. CASE REPORT: A 38-year-old man presented with a history of ascending paresthesia and bilateral facial droop since 5 days before admission. The medical history was positive for flulike symptoms affecting all the members of his family. The neurological examination was notable for bilateral peripheral facial paralysis, generalized areflexia, and derceased sensation in distal limbs. The cerebrospinal fluid analysis revealed an albuminocytologic dissociation. In addition, the electromyography-nerve conduction study findings were suggestive of acute axonaldemyelinating polyneuropathy. Meanwhile the patient was treated with a diagnosis of GuillainBarré syndrome, his 14-year-old daughter presented with a history of progressive paresthesia and weakness. Similar to her father, the paraclinical evaluations were consistent with Guillain-Barré syndrome. Taking into account clinical findings and the outbreak of COVID-19, the suspicion of COVID-19 was proposed. Eventually, on the basis of throat swab samples stand on polymerase chain reaction, the patients were diagnosed with COVID-19. CONCLUSION: Our cases revealed the familial occurrence of Guillain-Barré syndrome after COVID-19 infection. The authors emphasize neurological complications of COVID-19

Association of COVID-19 infection and juvenile stroke: A case series

Ischemic stroke has been increasingly reported as a consequence of COVID-19 infection. However, the underlying etiology is not well determined. The objective of this study is to discuss association of juvenile stroke with COVID-19 infection. We analyzed 5 COVID-19 positive and stroke patients with a mean age of 41.2 years-old. Three patients developed large vessel occlusion, one small vessel occlusion and one PRES with superimposed lobar ICH, respectively. The mean initial NIHSS of our patients was 11.6. Except the one with massive cerebellar infarct, a desirable outcome occurred with a mean mRS 2.6 at discharge. The mean ESR and CRP level was elevated to 30.4 ml and 32 mg/dl. The severity of COVID-19 infection was considered mainly as mild. COVID-19 infection has the potential to induce hypercoagulability state contributing to stroke development even in the mild form of diseas
