Idiopathic pulmonary vein thrombosis: an under-recognised source of embolic stroke.

Embolic stroke due to pulmonary vein thrombosis is rare but may be associated with lung and left atrial tumours, pulmonary surgery, atrial fibrillation and radiofrequency ablation. It is very rarely idiopathic. A 23-year-old man developed acute onset of a left partial third nerve palsy and left ataxic hemiparesis.

IgG4-Related Neurological Disease: A Single Center Ambispective Study from South India.

IgG4-related disease (IgG4-RD) is an immune-mediated multi-system disorder. The nervous system (IgG4-RND) is rarely affected. We describe a short case series.

First-Ever Ischemic Stroke In Covid-19: How Is It Different? - A Stroke Registry-Based Study From South India.

Stroke associated with COVID-19 has been characterised in several multicentre retrospective studies and meta-analyses. However, they did not distinguish first-ever ischemic strokes (F-AIS). Therefore, we aimed to study the incidence, clinical characteristics, and outcomes of a cohort of F-AIS associated with COVID-19 during the first wave of the pandemic and compare this cohort with those of F-AIS without COVID-19, COVID-19 without stroke.

Guillain-Barré syndrome associated with SARS-CoV-2 vaccination: how is it different? a systematic review and individual participant data meta-analysis.

Purpose: An association between Guillain-Barré syndrome (GBS) and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccination has been reported. We aimed to summarize the clinical features of GBS associated with SARS-CoV-2 vaccination and determine the contrasting features from coronavirus disease-19 (COVID-19) associated GBS and GBS following other causes.

Materials And Methods: We performed PubMed search for articles published between 1 December 2020 and 27 January 2022 using search terms related to "SARS-CoV-2 vaccination" and "GBS".

Diagnosis and Severity Evaluation of Ulnar Neuropathy at the Elbow by Ultrasonography: A Case-Control Study.

Background: Traditional diagnostic techniques such as clinical examination and electrodiagnosis are less sensitive in diagnosing ulnar neuropathy at the elbow (UNE). Ultrasonography (USG) is increasingly being used to diagnose UNE. However, clinical applicability is limited by the lack of uniformity in the previous studies.

Decoding "guitar pick sign" in COVID-19-associated mucormycosis: A case series.

"Guitar pick sign," also referred to as posterior globe tenting, is a radiological surrogate marker of tense orbit and profound vision loss. It is seen commonly in traumatic retrobulbar hemorrhage and carotico-cavernous fistula and less frequently in orbital cellulitis, subperiosteal abscess, and invasive fungal infections. We report a case series of Coronavirus disease-19-associated rhino-orbito-cerebral mucormycosis with guitar pick sign, of which none survived, and discuss the causative pathomechanisms, severity grade, and the clinical relevance of this unique radiological finding.

Pathogenetic factors fanning the flames of COVID-19 to cause rhino-orbito-cerebral mucormycosis: An observational study.

Background And Aims: Published studies on coronavirus disease 19 (COVID-19) associated rhino-orbito-cerebral mucormycosis (CAROCM) were primarily descriptive. Therefore, we aimed to identify features of COVID-19 that could predispose to CAROCM and explore the pathogenic pathways.

Patients And Methods: This retrospective hospital-based study was done during the first (March 2020 - January 2021) and the second (February 2021 - June 2021) waves of the COVID-19 pandemic.

COVID-19 in Patients with Myasthenia Gravis: Mechanisms of Respiratory Failure.

This report describes a patient with thymomatous myasthenia gravis (MG) with aplastic anemia in pharmacological remission and COVID-19 who developed respiratory failure in the course of the disease and reviews the published literature on this topic. Analysis of the clinical characteristics of the eight patients with MG including our patient suggests two possible mechanisms for respiratory failure: myasthenic crisis (MC) or pulmonary complications of COVID-19. Patients with MC were young women in high-grade MGFA Class whereas patients with respiratory failure due to pulmonary complications of COVID-19 were elderly men in pharmacological remission or MGFA Class I.

Factors influencing nonadministration of thrombolytic therapy in early arrival strokes in a university hospital in Hyderabad, India.

Background: It is a well-known fact that very few patients of stroke arrive at the hospital within the window period of thrombolysis. Even among those who do, not all receive thrombolytic therapy.

Objective: The objectives of this study were to determine the proportion of early arrival ischemic strokes (within 6 h of stroke onset) in our hospital and to evaluate the causes of nonadministration of intravenous and/or intraarterial thrombolysis in them.
