Journey of Guillain Barre syndrome from the pre-pandemic era to the pandemic era: A 4-year retrospective study.

Aims: To study demographic and clinical profiles of Guillain Barre syndrome (GBS) in the pre-pandemic and coronavirus disease 2019 (COVID-19) pandemic era and to compare the GBS incidence, severity, and its outcome in the pre-pandemic and pandemic eras.

Methodology: This is a 4-year retrospective study done in a tertiary care hospital in Delhi, India, between March 2018 and March 2022. Patients were divided into the pre-pandemic era and pandemic era (2 years before and 2 years after March 2020).

SARS-CoV-2-associated haemorrhagic encephalitis mimicking Herpes encephalitis.

Although acute encephalopathy is quite commonly seen in patients of SARS-CoV-2 infection, encephalitis characterised by brain inflammation is relatively rare. Encephalitis caused by Herpes simplex type 1 is the most common cause of identified sporadic encephalitis, and early diagnosis and prompt treatment can prevent the devastating outcome. In this brief communication, we report a case of SARS-CoV-2 associated haemorrhagic encephalitis mimicking herpes encephalitis.

Does Etiology and Hypsarrhythmia Subtype Influence Outcome in West Syndrome? Challenges Encountered from a Referral Center Perspective.

Background: Prediction of outcome of West syndrome (WS) in relation to etiology and electrophysiology remain pertinent challenges.

Objective: This study aimed to compare electro-clinical and imaging characteristics between WS of "unknown-etiology"; "symptomatic"WS; to gauge the evolution and impact of electroencephalographic (EEG) patterns on seizure outcomes.

Materials And Methods: Electro-clinico-radiological data of 76 children with WS who were followed up for atleast 1 year was collected for reviewing clinical, therapeutic and EEG profiles (sub-typed as typical and modified hypsarrhythmia [HA]).

Curious case of steroid responsive diffuse anterior horn cell disease associated with COVID-19 infection.

Covid-19-associated neurological manifestations are being reported with increased frequency throughout the world. In a study from China, symptoms referable to peripheral nervous system (PNS) were described in approximately 9% of hospitalized Covid-19 patients. Common PNS symptoms reported in the study were loss of taste/smell and muscle pains.

Paraneoplastic cerebellar degeneration as a presenting manifestation of non-Hodgkin's lymphoma.

Background: Paraneoplastic Cerebellar degeneration (PCD) is one of the classical paraneoplastic syndromes (PNS) which is characterised by subacute onset, progressive cerebellar ataxia and is usually associated with small cell lung carcinoma, adeno carcinoma of breast and ovary followed by Hodgkin's lymphoma.

Objective: We herein report a case of subacute onset, progressive cerebellar ataxia in a 37-year-old female, who on evaluation was found to have non-Hodgkin's lymphoma and experienced good clinical response to treatment.

Discussion: As compared to solid tumours, chances of association of PNS with Lymphomas is quite low and there are only few case reports in the literature showing association of PCD with non-Hodgkin's lymphoma.

Covid-19 associated Guillain-Barre Syndrome: Contrasting tale of four patients from a tertiary care centre in India.

Background: Globally, more than 12 million people have been infected with COVID -19 infection till date with more than 500,000 fatalities. Although, Covid-19 commonly presents with marked respiratory symptoms in the form of cough and dyspnoea, a neurotropic presentation has been described of late as well.

Objective: In this brief communication we report four cases of Covid-19 who presented to our hospital with features suggestive of Guillain-Barre Syndrome (GBS).

Clinico-Genotypic Correlation: Recurrent Attacks of Paralysis and Skeletal Muscle SCN4A Mutation (p.Ile693Thr).

Skeletal sodium channel mutations have been known to demonstrate a multitude of clinical manifestations of which one such commonly known entity is paramyotonia congenita. We describe the clinical features of proband in our case report and the various phenotypic manifestations described with the mentioned mutation from different centres. Our case serves to highlight the heterogeneity that exists in SCN4A mutations and the possible effect of other genetic/environmental factors in determining the final phenotype.

Novel Face-Name Paired Associate Learning and Famous Face Recognition in Mild Cognitive Impairment: A Neuropsychological and Brain Volumetric Study.

Purpose: To assess visual associative learning and famous face recognition ability among subjects with stable amnestic mild cognitive impairment (MCI) relative to early stage dementia due to Alzheimer's disease (AD) and cognitively normal healthy controls (NC) and to correlate these differences with volumetric changes on MRI.

Methods: A hospital-based cross-sectional observational study was conducted on 61 participants. The subjects underwent neuropsychological evaluation, including validated newly designed tests for novel face-name paired association learning recall and famous face recognition.

Prevalence of psychiatric comorbidities in chronic obstructive pulmonary disease patients.

Introduction: Psychiatric disorders, especially anxiety and depression have been reported to have an increased prevalence in chronic obstructive pulmonary disease (COPD) patients, but there is a paucity of data from India.

Aims And Objectives: Aim of our study is to study the frequency of psychiatric comorbidities in COPD patients and their correlation with severity of COPD, as per global initiative for obstructive lung disease guidelines.

Materials And Methods: This study was conducted in outpatient department of a tertiary care hospital (King George's Medical University).

Rhabdomyolysis and acute kidney injury in dengue fever.

Rhabdomyolysis is a rare but potentially lethal complication of severe dengue fever. We present a case of 21-year-old man with fever, bodyache and black coloured and decreasing amount of urine. He was positive for NS1 (non-structural protein-1) antigen and IgM antibody for dengue.
