Introduction Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the global spread of coronavirus disease (COVID-19). Our understanding of the impact this virus has on the nervous system is limited. Our review aims to inform and improve decision-making among the physicians treating COVID-19 by presenting a systematic analysis of the neurological manifestations experienced within these patients. Methods Any study, released prior to May 20, 2020, that reported neurological manifestations in patients infected by SARS-CoV-2 was systematically reviewed using the PRISMA (Preferred Reporting Items for Systemic review and Meta-Analysis) statement. Results Our systematic review included data from 37 articles: twelve retrospective studies, two prospective studies, and the rest case reports/series. The most commonly reported neurological manifestations of COVID-19 were myalgia, headache, altered sensorium, hyposmia, and hypogeusia. Uncommonly, COVID-19 can also present with central nervous system manifestations such as ischemic stroke, intracerebral hemorrhage, encephalo-myelitis, and acute myelitis, peripheral nervous manifestations such as Guillain-Barré syndrome and Bell’s palsy, and skeletal muscle manifestations such as rhabdomyolysis. Conclusion While COVID-19 typically presents as a self-limiting respiratory disease, it has been reported in up to 20% of patients to progress to severe illness with multi-organ involvement. The neurological manifestations of COVID-19 are not uncommon, but our study found most resolve with treatment of the underlying infection. Although the timeliness of this review engages current challenges posed by the COVID-19 pandemic, readers must not ignore the limitations and biases intrinsic to an early investigation.

Background Intravenous thrombolysis has been recently introduced in Nepal for the management of acute ischemic stroke. Pre-hospital delay is one of the main reasons that hinder thrombolytic therapy. The objective of this study was to evaluate the status of prehospital delay and thrombolysis in Nepal. Methods Data were prospectively collected from patients of both genders, age >  18 years who arrived at the emergency department (ED) with symptoms and neuroimaging findings consistent with an ischemic stroke. Patient data were obtained from ED form and standard questionnaires were used to assess factors resulting in prehospital delay. Modified Rankin scale and National Institute of Health stroke scale were used to assess the degree of disability and severity of stroke respectively. Results A total of 228 patients were enrolled in the study between August 2017 and August 2018. Only 46 (20.17%) patients arrived within the time frame for thrombolysis. Onset at daytime (OR: 4.07; 95% CI: 1.65–10.1; p = 0.001), stroke symptoms facial deviation (OR: 5.03; 95% CI: 2.47 to 10.26; p = 0.000) and speech disturbances (OR: 2.34; 95% CI: 1.06 to 5.1; p = 0.021), identification of stroke (OR: 22.36; 95% CI: 9.42–53.04; p = 0.000), rushing to ED after onset of symptoms (OR: 2.93; 95% CI: 1.5–5.7; p = 0.001), awareness of treatment of stroke (OR: 10.21; 95% CI: 4.8–21.6; p = 0.000), direct presentation (OR: 4.2; 95% CI: 2.09–8.66; p = 0.000), the distance less than 20 km (OR: 7.9; 95% CI: 3.8–16.5; p = 0.000), and education above high school (OR:4.85; 95% CI: 2.2–10.5; p = 0.000) were associated with early arrival. Heavy traffic, income below 1000 USD per annum and diabetes mellitus were associated with delayed arrival to ED. Out of 46 early arrival patients, only 30 patients (13.15%) received tissue plasminogen activator during the study period, while others were deprived because of their inability to afford the treatment cost. Conclusion Community-based intervention to spread awareness, establishing comprehensive stroke centers, training specialists, improving emergency services, establishment of telestroke facilities and encouraging the use of low-cost tenecteplase as an alternative to alteplase can help improve care for stroke patients in Nepal.

Background Interleukin-6-receptor inhibitors like Tocilizumab and Satralizumab are showing promising results in the treatment of Neuromyelitis Optica spectrum disorder (NMOSD). We aimed to investigate the efficacy and safety of various Interleukin-6-receptor inhibitors in the management of NMO/NMOSD. Methods PubMed, Embase, and The Cochrane Library were systematically searched for suitable studies. Change in Annualized Relapse Ratio (ARR), Change in Extended Disability Status Scale (EDSS) s, the proportion of relapse-free patients and proportion of patients with adverse events, including serious adverse events and mortality were the parameters considered for the meta-analysis for Tocilizumab. Mean difference (MD) with 95% CI was used to quantify the change in ARR and change in EDSS before and after treatment. A forest plot was prepared to indicate the efficacy and adverse effects outcomes. The results were compared with those of Satralizumab included in two trials. Results A total of nine studies with 202 patients were included in our study. Tocilizumab found a good proportion (76.95% CI: 0.61–0.91; p < 0.001) of relapse free patients at follow up. It also significantly reduced mean ARR (mean difference: -2.6, 95% CI: − 2.71 to − 1.68; p < 0.001) and but did not show significant difference in change in EDSS score (mean difference = − 0.79, 95% CI: − 1.89 to − 0.31; p = 0.16). Also, the toxicity profile of Tocilizumab was acceptable considering the proportions of patients with adverse events 56% (95% C.I.;0.27–0.85, I2 = 88.95%, p < 0.001), proportions of patients with serious adverse events 11% (95% C.I.; 0.05 to 0.17, I2 = 0%, p < 0.001) and zero treatment related deaths. SAkura studies for Satralizumab showed similar relapse free patients (70% to 80%) and reduction of ARR and EDSS from baseline. Some studies of Tocilizumab have shown to reduce pain and fatigue while trials of Satralizumab had non-significant findings. Conclusion Interleukin-6-receptor inhibitors therapy showed a promising result with good efficacy and acceptable adverse events profile for treatment of NMOSD.

Autoimmune encephalitis (AE) is a rare but debilitating neurological disease in which the body develops antibodies against its own neurons and causes inflammation of the brain. It affects all age groups but children and women are more commonly affected. Patients may develop a rapidly progressive encephalopathy syndrome, manifested by changes in mental state and a number of neurological symptoms including impaired memory and cognition, vision and speech problems, impaired coordination, movement disorders and seizures, and psychiatric symptoms including psychosis, euphoria, aggressiveness and compulsiveness, inappropriate sexual behavior, and panic attacks. Symptoms may progress to loss of consciousness or even coma. 1,2

Cerebral venous thrombosis (CVT) is caused by partial or complete occlusion of the major cerebral venous sinuses or the smaller feeding cortical veins which predispose to the risk of venous infarction and hemorrhage. Current guidelines recommend treating CVT with either low-molecular-weight heparin (LMWH) or unfractionated heparin (UFH) followed by an oral vitamin K antagonist (VKA) for 3-12 months. Direct oral anticoagulants (DOACs) have already established benefit over warfarin as a long-term treatment of symptomatic venous thromboembolic disorder like deep vein thrombosis (DVT), and pulmonary embolism (PE) given its equal efficacy and better safety profile. The benefit of DOACs over warfarin as a long-term anticoagulation for CVT has likewise been extensively studied, yet it has not been approved as first-line therapy in the current practice. We therefore performed a systematic review and meta-analysis of relevant studies to generate robust evidence regarding the safety and efficacy of DOACs in CVT. This meta-analysis demonstrates that the use of DOACs in CVT has similar efficacy and safety compared to VKAs with better recanalization rate.

Background and Aims Telemedicine is the delivery of healthcare services from distance using information and communication technology. It helps in overcoming the geographical physical barrier, increasing access to the healthcare services. Telemedicine has been growing in Nepal, with several hospitals and medical organizations providing services since 2006. COVID‐19 pandemic ignited significant interests in it, which previously remained unnoticed, realizing its importance for the present and future. The objective of this study was to evaluate the knowledge and attitude toward telemedicine among medical students in Nepal. Methods An observational study among medical students in 19 medical colleges in Nepal was performed from May to June using Google forms. The survey consisted of 27 questions including information on demography and telemedicine exposure, its status in Nepal, interest, and plans for its future utilization. Results Of 146 total surveyed students, 77.4% (n = 113) provided their views regarding telemedicine. Among students with knowledge of telemedicine, only 8.8% (n = 10) had attended some training. Only 6% (n = 4) of those who had previously consulted through telemedicine labeled their experience as poor. Exactly 88.5% (n = 100) were not satisfied with present telemedicine practices and coverage and 43.4% (n = 49) were optimistic about using telemedicine in future. Irrespective of location of medical colleges (Kathmandu Valley or outside) or levels of study (preclinical or clinical), students had similar knowledge and attitude regarding telemedicine. Conclusion The participants have good knowledge regarding the importance of telemedicine but only few of them are educated regarding its usage. Despite limited exposure to telemedicine, participants advocate for expansion and wide use of telemedicine due to economy, technological advancement, and topographic diversities. Internet, sense of reliability, privacy issue, and lack of proper curriculum seem to have raised question on their positive attitude. Formal and structured education may enable optimistic aspirants to integrate telemedicine skills with medical care delivery with ease.

Objective: This is a critical review of studies aiming to assess the safety and efficacy of monoclonal antibodies as compared with the classical regimen in patients with neuromyelitis optica spectrum disorder.Methods: Various electronic databases were searched for original articles reporting results from the use of monoclonal antibodies in neuromyelitis optica spectrum disorder. The Expanded Disability Status Scale and annualized relapse rate score before and after treatment were the primary effect measures. The pooled standardized mean difference with 95% CI was calculated using the random effects model. The heterogeneity of the included studies was calculated using Cochran's Q test and I 2 statistics. Results:Of 36 included studies, meta-analysis was carried out from 27 studies. The pooled analysis of 1010 patients showed a mean reduction in the mean annualized relapse rate ratio after tocilizumab therapy −2.45 (95% CI −3.13 to −1.77) to be higher compared with rituximab −1.49 (95% CI −1.81 to −1.17). Likewise, the mean reduction in the Expanded Disability Status Scale after tocilizumab was higher −1.10 (95% CI −1.75 to −0.44) compared with rituximab −0.80 (95% CI −1.11 to −0.48). Conclusion:Tocilizumab has a greater effect than rituximab in terms of the reduction of the annualized relapse rate and Expanded Disability Status Scale in neuromyelitis optica spectrum disorder patients. The greater efficacy of tocilizumab could result from its multiple dynamic pharmacodynamics (i.e. its effect on interleukin-6-dependent inflammatory processes, involving CD20-negative plasmablasts, pathogenic T cells and regulatory T cells) and to some degree due to heterogeneity in our study. Satralizumab (monotherapy or add-on), eculizumab and inebilizumab (monotherapy) are effective in aquaporin-4-positive cases with good safety profiles. Ublituximab, bortezomib, bevacizumab and C1-esterase inhibitors are both effective and safe add-on drugs.
