COVID-19 vaccine associated demyelination & its association with MOG antibody.

BACKGROUND: ChAdOx1-S (Covishield™/Vaxzervria, AstraZeneca) and BBV152 (Covaxin) SARS-CoV-2 vaccines are proven to be safe and effective, but rare complications have been reported. OBJECTIVE: To describe reports of central nervous system (CNS) demyelination following ChAdOx1-S and BBV152 vaccinations. METHODS & RESULTS: We report 29 (17 female; mean 38 years) cases of CNS demyelination; twenty-seven occurred in temporal association with ChAdOx1-S vaccine; two in association with BBV152 vaccine. Eleven patients had presentation with myelitis, six patients developed optic neuritis, five had acute demyelinating encephalomyelitis, three presented with brainstem demyelination, and four had multiaxial involvement. Myelin oligodendrocyte glycoprotein (MOG) antibodies were positive in ten patients. One patient with ADEM and tumefactive demyelinating lesions died after a prolonged intensive care unit stay and superimposed infection. As compared to the control group (87); the postvaccinial cases were found to have a significantly higher mean age, presence of encephalopathy (p value:0.0007), CSF pleocytosis (p value: 0.0094) and raised CSF protein (p value: 0.0062). CONCLUSIONS: It is difficult to establish a causal relationship between vaccination and neurological adverse events such as demyelination. The temporal association with the vaccination and the presence of MOG antibodies raises the possibility of an immunogenic process triggered by the vaccine in susceptible individuals.

Clinical characteristics, treatment and long-term prognosis in patients with anti-NMDAR encephalitis.

OBJECTIVES: We aimed to (i) analyse the clinical characteristics, treatment outcome and long-term prognosis of anti-NMDAR encephalitis and (ii) study the differences between paediatric and adult patients. METHODS: This was a chart review of all patients with anti-NMDAR encephalitis. RESULTS: There were 28 patients with 18 patients belonging to the paediatric (<18 years) age group. There was female (94%) preponderance in the paediatric age group, while in adult patients, there was no gender predilection (p=0.006). There was no significant difference in clinical feature, outcome or number of relapses between paediatric and adult population groups. MRI brain was abnormal in 53% of patients. Among the 15 patients with MRI abnormalities at the onset, 53% had poor functional outcome at 1 year, while in 12 patients with normal initial MRI brain, only 8% had poor functional outcome at 1 year (p =0.01). Nearly 53% of patients with abnormal MRI at presentation had at least one clinical relapse within 2 years while in patients with normal MRI at presentation, 15% had a clinical relapse (p=0.037). EEG abnormalities were noticed in 71% of patients; among them, 40 and 15% had poor functional outcome at 1 and 2 years respectively. In comparison, those with normal first EEG at onset, 12% had poor functional outcome at 2 years (p=0.57). CONCLUSIONS: Both paediatric and adult patients presented with similar clinical features but the paediatric population had female preponderance. The functional outcome and number of relapse were comparable in both the paediatric and adult groups. Patients with parenchymal changes on MRI and abnormal EEG showed poorer response compared to those with normal MRI and/or EEG at the onset. Patients have lesser severity of symptoms at relapse than in the first episode. An early diagnosis and treatment are essential for better long-term functional outcome.

Three-dimensional neuromelanin-sensitive magnetic resonance imaging of the substantia nigra in Parkinson's disease.

BACKGROUND AND PURPOSE: The aim was to investigate the diagnostic utility of signal intensity measurement of the substantia nigra pars compacta (SNc) using three-dimensional (3D) neuromelanin-sensitive magnetic resonance imaging (MRI), for discrimination of patients with Parkinson's disease (PD) from healthy controls. METHODS: T1-weighted neuromelanin-sensitive images of 16 patients with PD and 15 controls were quantitatively analyzed by placing circular 10 mm2 regions of interest over the central and lateral parts of the bilateral SNc and anterior to the cerebral aqueduct at three levels of the midbrain. Signal intensities and contrast ratios (CRs) were calculated, after which significant differences, correlations, sensitivity and specificity were calculated. RESULTS: The CRs of the central and lateral SNc were significantly lower in patients with PD. Lateral CRs were lower than the central CRs in both groups and significantly correlated with duration of illness. CRs of central and lateral parts of the SNc also correlated with the Unified Parkinson's Disease Rating Scale III OFF state scores. Receiver operating characteristic analysis revealed lateral CRs to be more sensitive and central CRs to be more specific for the discrimination of patients with PD from controls. CONCLUSIONS: Contrast ratio analysis of the SNc using 3D neuromelanin-sensitive MRI may serve as a quick and accurate tool to discern between patients with PD and healthy controls.

"I swear, I can't stop it!" - A case of severe Tourette's syndrome treated with deep brain stimulation of anteromedial globus pallidus interna.

INTRODUCTION: Tourette's syndrome (TS) is a complex neuropsychiatric disorder characterized by the presence of multiple motor and vocal tics. Here, we report the case of a young man with severe TS refractory to multiple medications who underwent deep brain stimulation (DBS), which was successful in substantially ameliorating his tics. To our knowledge, this is the first such report from India and South Asia. CASE REPORT: An 18-year-old right-handed male patient was diagnosed with TS at the age of 10 years. He had facial and ocular tics. He was also hitting his fist against his chest and shouting obscenities. The manifestations would be present in every waking hour with a maximum tic free interval of 15-20 minutes. They would often result in self-injury or damage to objects. He would have frequent crying spells, anger outbursts, and death wishes. As tics became highly conspicuous and socially inappropriate, he dropped out of school and remained almost completely house-bound for the preceding year. On evaluation, he scored 96 (46 on tic-severity subscale and 50 on impairment subscale) of a maximum of 100 on the Yale Global Tic Severity Scale. (YGTSS). MANAGEMENT: After failure of multiple combinations of medicines, repetitive transcranial magnetic stimulation, and behavioural therapies, he successfully underwent DBS to bilateral anteromedial globus pallidus interna. CONCLUSION: Tic severity reduced substantially post-surgery, with the YGTSS score improving by more than 72%. These improvements were sustained on follow-up visits with the patient successfully returning to join college. To our knowledge, this is the first such report from India and South Asia.

Clinical and imaging characteristics of 16 patients with autoimmune neuronal synaptic encephalitis.

OBJECTIVES: Autoimmune neuronal synaptic encephalitis (AIE) encompasses a heterogeneous group of disorders characterized by immune-mediated neuronal cell destruction. In this study, we aim to study the clinical features, imaging profile and treatment outcome of patients with AIE. METHODS: This is a chart review of 16 (M: F-3:13) patients with AIE from 2011 to 2015. RESULTS: Among the patients, 10 had anti-NMDA, 4 had anti-TPO, and 2 had anti-VGKC antibody positivity. Cognitive impairment and seizures were the predominant symptoms present in nearly all patients, followed by psychiatric disturbances (87.5%), mutism (62.5%), movement disorders (62.5%), myoclonic jerks (37.5%) and visual hallucinations (18.75%). Magnetic resonance imaging (MRI) of the brain was available in 15 patients; it was abnormal in 53.3% patients. Abnormalities were seen in all patients with anti-VGKC positivity; and, 60% of patients with anti-NMDA positivity. Imaging was normal in 26.7% of the patients (3: anti-NMDA; and, 1: anti-TPO positivity); and, diffuse cerebral atrophy was noted in rest of the 20% (3: anti-TPO positivity) patients. All patients improved gradually with immunomodulation. CONCLUSIONS: All patients with anti-VGKC, anti-NMDA and anti-TPO antibody positivity presented with a triad of behavioral changes, impaired cognition and seizures. Mutism was a predominant symptom in patients with an anti-NMDA antibody positivity, which may help in the early identification of this disorder. MRI brain showed changes restricted to limbic structures in anti-NMDA and anti-VGKC antibody positivity. An early diagnosis and treatment of autoimmune encephalitis is essential for a better outcome and for prevention of long-term sequel.

Repetitive transcranial magnetic stimulation induced modulations of resting state motor connectivity in writer's cramp.

BACKGROUND AND PURPOSE: Writer's cramp (WC) is a focal task-specific dystonia of the hand which is increasingly being accepted as a network disorder. Non-invasive cortical stimulation using repetitive transcranial magnetic stimulation (rTMS) has produced therapeutic benefits in some of these patients. This study aimed to visualize the motor network abnormalities in WC and also its rTMS induced modulations using resting state functional magnetic resonance imaging (rsfMRI). METHODS: Nineteen patients with right-sided WC and 20 matched healthy controls (HCs) were prospectively evaluated. All patients underwent a single session of rTMS and rsfMRI was acquired before (R1) and after (R2) rTMS. Seed-based functional connectivity analysis of several regions in the motor network was performed for HCs, R1 and R2 using SPM8 software. Thresholded (P < 0.05, false discovery rate corrected) group level mean correlation maps were used to derive significantly connected region of interest pairs. RESULTS: Writer's cramp showed a significant reduction in resting state functional connectivity in comparison with HCs involving the left cerebellum, thalamus, globus pallidus, putamen, bilateral supplementary motor area, right medial prefrontal lobe and right post central gyrus. After rTMS there was a significant increase in the contralateral resting state functional connectivity through the left thalamus-right globus pallidus-right thalamus-right prefrontal lobe network loop. CONCLUSIONS: It is concluded that WC is a network disorder with widespread dysfunction much larger than clinically evident and changes induced by rTMS probably act through subcortical and trans-hemispheric unaffected connections. Longitudinal studies with therapeutic rTMS will be required to ascertain whether such information could be used to select patients prior to rTMS therapy.

White matter correlates of cognitive impairment in essential tremor.

BACKGROUND AND PURPOSE: Impairment of cognitive functions occurs in essential tremor, though the mechanism is largely unknown. The aim of this study was to find microstructural correlates of cognitive dysfunction seen in essential tremor by using DTI and neuropsychological assessment. MATERIALS AND METHODS: Fifty-five patients with essential tremor and 55 matched healthy controls were evaluated. Essential tremor was diagnosed by using the National Institutes of Health criteria. Subjects were assessed by using a structured neuropsychological battery. DTI data were acquired by using 3T MR imaging and were analyzed by using tract-based spatial statistics. Fractional anisotropy, mean diffusivity, radial diffusivity, and axial diffusivity were analyzed. RESULTS: Patients were considered cognitively impaired when the test score was 1.5 SDs below or above the mean of healthy controls (depending on the type of test) in ≥3 neuropsychological tests. Patients with cognitive impairment had significantly higher mean diffusivity, radial diffusivity, and axial diffusivity values in the bilateral frontoparietal regions. In patients with cognitive impairment, mean diffusivity, radial diffusivity, and axial diffusivity showed correlations with various neuropsychological test scores. Executive function correlated with DTI measures of the frontal white matter, cingulum, inferior superior longitudinal and uncinate fasciculi, anterior thalamic radiations, and posterior lobe of the cerebellum. Visuospatial function correlated with the right parieto-occipital lobe, whereas visual-verbal memories correlated with the anterior thalamic radiations, inferior longitudinal and uncinate fasciculi, and the posterior lobe of the cerebellum. No significant correlations were found between fractional anisotropy and any of the neuropsychological test scores. CONCLUSIONS: The present study demonstrates a correlation between neuropsychological test scores and DTI measures, suggesting a neuroanatomic basis for cognitive impairment seen in patients with essential tremor.

Rapid eye movement sleep behaviour disorder in young- and older-onset Parkinson disease: a questionnaire-based study.

BACKGROUND: Rapid eye movement sleep behavior disorder (RBD) is common in Parkinson disease (PD). OBJECTIVES: To determine the frequency of clinically probable RBD (cpRBD) in young-onset (21 to < or =40 years; YOPD) and older-onset PD (>40 years; OOPD) and characterize its pattern. METHODS: A total of 156 patients with PD (YOPD-51, OOPD-105) were clinically examined and the presence of RBD was diagnosed using the minimal criteria for diagnosis of RBD (International Classification of Sleep Disorders, ICSD-1). RBD screening questionnaire based on the minimal criteria was used. The bed-partners were also interviewed with Mayo sleep questionnaire. Other scales included Unified Parkinson Disease Rating Scale part III (UPDRS III), Hoehn & Yahr stage, Mini Mental Status Examination, Pittsburgh Sleep Quality Index, Parkinson Disease Sleep Scale, Epworth Sleep Scale, Hamilton Anxiety Rating Scale and Hamilton Depression Rating Scale. RESULTS: cpRBD was diagnosed in 30 (19.2%) patients, majority being OOPD rather than YOPD (86.7% vs. 13.3%; P=0.01). The frequency of RBD was significantly higher (P=0.016) in OOPD (24.8%) compared to those with YOPD (7.8%). Most often (72.4%) RBD occurred after the onset of parkinsonian symptoms. RBD was independently associated with higher global PSQI scores, total ESS scores and total PDSS scores after adjusting for the effects of age, gender, Hoehn & Yahr stage and duration of illness. CONCLUSIONS: Patients with RBD were older with later-onset motor symptoms, a more advanced stage, poorer sleep quality, and more frequent daytime sleepiness. Older-onset PD had a higher frequency of RBD than young-onset PD.

Association between cortical volume loss and cognitive impairments in essential tremor.

BACKGROUND AND PURPOSE: Impairment of cognitive functions occurs in essential tremor (ET) although the mechanism is largely unknown. A possible association between cognitive performance and brain atrophy in ET patients was examined using neuropsychological tests and voxel-based morphometry (VBM). METHODS: Twenty-five patients with ET and 25 matched healthy controls were evaluated. ET was diagnosed using the National Institutes of Health collaborative genetic criteria. Severity of tremor was assessed using the Fahn-Tolosa-Marin (FTM) tremor rating scale. Subjects were assessed using a structured neuropsychological battery. Brain images were acquired using a 3T magnetic resonance imaging scanner. VBM analysis was performed using Statistical Parametric Mapping 8. RESULTS: The age of the patients was 45.0 ± 10.7 years and of controls 45.4 ± 10.7 years. Tremor duration was 9.84 ± 6.63 years and total FTM score was 37.34 ± 17.67. Patients were divided into two groups: ETCI with cognitive impairment (three or more abnormal neuropsychological tests, 1.5 standard deviation criterion) and ETNCI without cognitive impairment. Compared with controls, the ETCI group had significantly impaired performance in neuropsychological tests. One-way analysis of variance was performed between the three groups (ETCI, ETNCI, controls) followed by the two-sample t test. Compared with controls, grey matter volume (GMV) loss was observed in ETCI in the cerebellum (anterior and posterior lobes) and medial frontal gyrus. GMV loss was observed in ETCI compared with ETNCI in the medial frontal gyrus, post central gyrus, anterior cingulate and insula. Impairment in neuropsychological tests significantly correlated with GMV of the medial frontal gyrus, superior parietal lobe, middle temporal gyrus, occipital lobe, lentiform nucleus, insular and cingulate cortices and cerebellum posterior lobe in ETCI. CONCLUSIONS: A correlation between neurocognitive deficits in ETCI and GMV was observed suggesting that grey matter atrophy appears to be a correlate of cognitive impairment in ET.

Radiation mapping inside the bunkers of medium energy accelerators using a robotic carrier.

The knowledge of ambient and peak radiation levels prevailing inside the bunkers of the accelerator facilities is essential in assessing the accidental human exposure inside the bunkers and in protecting sensitive electronic equipments by minimizing the exposure to high intensity mixed radiation fields. Radiation field mapping dynamically, inside bunkers are rare, though generally dose-rate data are available in every particle accelerator facilities at specific locations. Taking into account of the fact that the existing neutron fields with a spread of energy from thermal up to the energy of the accelerated charged projectiles, prompt photons and other particles prevailing during cyclotron operation inside the bunkers, neutron and gamma survey meters with extended energy ranges attached to a robotic carrier have been used. The robotic carrier movement was controlled remotely from the control room with the help of multiple visible range optical cameras provided inside the bunkers and the wireless and wired protocols of communication helped its movement and data acquisition from the survey meters. Variable Energy Cyclotron Centre, Kolkata has positive ion accelerating facilities such as K-130 room Temperature Cyclotron, K-500 Super Conducting Cyclotron and a forthcoming 30 MeV Proton Medical Cyclotron with high beam current. The dose rates data for K-130 Room Temperature Cyclotron, VECC were collected for various energies of alpha and proton beams losing their total energy at different stages on different materials at various strategic locations of radiological importance inside the bunkers. The measurements established that radiation levels inside the machine bunker dynamically change depending upon the beam type, beam energy, machine operation parameters, deflector condition, slit placement and central region beam tuning. The obtained inference from the association of dose rates with the parameters like beam intensity, type and energy of projectiles, helped in improving the primary beam transmission and minimizing the ambient radiation fields inside the bunkers.

Subcortical structures in progressive supranuclear palsy: vertex-based analysis.

BACKGROUND AND PURPOSE: To study the abnormalities of deep grey matter (GM) structures in patients with progressive supranuclear palsy (PSP) using MR volumetry and shape analysis techniques. METHODS: Twenty-eight patients with PSP and 25 matched controls (all were right handed) were evaluated using standard clinical scales. MRI was performed on a 3 tesla MRI scanner using standard protocol which included T1-3D Turbo Field-Echo images with 1-mm slice thickness. The volumes of GM and white matter, total brain and the deep subcortical GM structures, including hippocampus, amygdala, caudate, putamen, globus pallidus and thalamus were extracted using a fully automated tool. Univariate analysis of covariance, adjusted for intracranial volume (ICV), sex and age, was used to explore group differences. Shape analysis was also performed using automated software with age, sex and total brain volume as covariates of no interest in the statistical design at P < 0.05 (FDR corrected). RESULTS: The patients with PSP had significantly lower volumes of bilateral thalami, hippocampus, pallidum and brainstem. Shape analysis of GM structures showed significant surface reduction in bilateral thalami and head of right caudate nucleus. CONCLUSIONS: MR volumetry showed abnormalities of various deep GM structures. Shape analysis also revealed focal surface contractions in multiple subcortical structures. Our study highlights the usefulness of this novel technique in detecting abnormalities of deep GM structures.

Non-motor features in essential tremor.

INTRODUCTION: Essential tremor (ET) is increasingly recognized to have several non-motor manifestations. The aim of this study was to determine the prevalence of non-motor manifestations in ET and its impact on the quality of life (QOL). METHODS: This was a cross-sectional case-control questionnaire-based study. The subjects were 50 patients with ET and 50 matched healthy controls. All subjects were assessed by Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Parkinson Fatigue Scale, Brief Pain Inventory, Hamilton Anxiety Rating Scale, and Hamilton Depression Rating Scale. In addition, QOL in Essential Tremor questionnaire was administered to patients with ET. RESULTS: Patients with ET, when compared with controls, had significantly higher prevalence and higher mean scores of sleep disturbances (46% vs 8%, P < 0.001; 5.9 ± 4.6 vs 2.6 ± 2.3, P < 0.001), fatigue (30% vs 8%, P = 0.009; 5.8 ± 0.8 vs 2.5 ± 0.4, P < 0.001), anxiety (66% vs 18%, P = 0.009; 7.4 ± 9.0 vs 0.7 ± 2.6, P < 0.001), depression (44% vs 8%, P = 0.009; 7.8 ± 7.9 vs 1.7 ± 3.3, P < 0.001) as well as higher mean score of pain severity (1.9 ± 2.3 vs 0.6 ± 1.2, P = 0.001) and interference owing to pain (2.0 ± 2.9 vs 0.5 ± 1.2, P = 0.001). Following hierarchical regression analysis, depression was the only non-motor feature that affected the QOL. CONCLUSION: There was a significantly higher prevalence and greater severity of sleep disturbances, fatigue, pain, anxiety, and depression in patients with ET and depression significantly affected the QOL.

A clinical profile of 103 patients with secondary movement disorders: correlation of etiology with phenomenology.

BACKGROUND AND PURPOSE: Studying patients with secondary movement disorders (SMD) provides a unique opportunity to determine the correlation between the etiology and phenomenology of movement disorders. METHODS: This was a prospective study of 103 patients (43 women, 60 men; age=28.7±17.3 years; range=2-70 years) with SMD, in a tertiary hospital over 4 years. RESULTS: The mean age of onset of SMD was 24.3±19.7 years, and duration of symptoms was 4.3±7.1 years (42 days to 40 years). Patients with pure tremor, pure dystonia (DYS), or a combination of tremor with dystonia had longest latency (10.9-18.5 months), whereas those with parkinsonism (PAR) and hemiballismus (HMB) had shorter latency (2.7-3.0 weeks). Pure dystonia was most prevalent (30.1%) followed by dystonia plus (13.6%), tremor (12.6%), PAR (11.7%), HMB (8.7%), mixed SMD (7.8%), tremor with dystonia (6.8%), myoclonus (5.8%), and chorea (2.9%). In approximately 60% of patients, the underlying etiologies were vascular (VAS), infections, and space-occupying lesions (SOL), and 25% had SMD following trauma or hypoxia (HYP). With reference to specific etiologies, the most frequent SMDs were tremor following SOL (46%), post-traumatic syndromes (25%), dystonia following HYP (56%), VAS lesions (50%), and infections (28%). With reference to specific SMDs, the most common etiologies were VAS for dystonia (39%), SOL for tremor (67%), and PAR (31%), and both SOL and trauma (37.5% each) for tremor with dystonia. CONCLUSIONS: Our study highlights the spectrum of SMDs and the lack of correlation between types of SMDs and underlying etiologies. Preventable causes such as infections, HYP, trauma, and kernicterus still play a major role in pathogenesis of SMD.

Subclinical pulmonary dysfunction in spinocerebellar ataxias 1, 2 and 3.

OBJECTIVES: Evaluation of pulmonary function in patients with spinocerebellar ataxias (SCA) 1, 2 and 3 without clinical evidence of pulmonary dysfunction. METHODS: Thirty patients (F:M = 7:23; age: 35 ± 11.3 years; SCA1 - 13, SCA2 - 9 and SCA3 - 8) without clinical manifestations of respiratory dysfunction and 30 controls underwent pulmonary function tests. The percentage predicted values of forced vital capacity (FVC), volume of air exhaled during first second of FVC (FEV1), peak expiratory flow rate (PEFR) and maximal voluntary ventilation (MVV), actual values of maximal inspiratory and expiratory pressures (MIP and MEP in mmHg), and ratios of actual values of FEV1/FVC (%) and FEV1/PEFR (ml/l/min) were analyzed. RESULTS: Compared with controls SCA patients had significant reductions of FVC (71.1 ± 17.5 vs 85.5 ± 18.7; P < 0.01), PEFR (51.5 ± 20.7 vs 77.1 ± 24.9; P < 0.001), MVV (64.4 ± 21.6 vs 97.2 ± 22.7; P < 0.001), MIP (27.7 ± 16.8 vs 50.1 ± 15.1; P < 0.001) and MEP (38.1 ± 18.7 vs 74.7 ± 16.0; P < 0.001), elevation of FEV1/PEFR (10.5 ± 2.8 vs 7.4 ± 2.1; P < 0.001), but no significant change of FEV1 and FEV1/FVC. FEV1/PEFR correlated positively with illness duration and MVV negatively with severity of illness. CONCLUSIONS: The present study showed subclinical restrictive type of pulmonary dysfunction in SCA, and possible presence of upper airway obstruction. Chest physiotherapy and breathing exercises should be introduced early in management of SCA.

Community-acquired methicillin-resistant Staphylococcus aureus pyomyositis with myelitis: A rare occurrence with diverse presentation.

Staphylococcus aureus is the most common bacterial pathogen implicated in pyomyositis. There are increasing reports of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections. The present case report brings out the diverse clinical manifestations of MRSA infection in the form of paraspinal pyomyositis, myelitis, spinal osteomyelitis, and pneumonia. Molecular typing of the organism confirmed the diagnosis. Patient was successfully treated with vancomycin and surgical drainage. Consideration of the possibility of methicillin-resistance and appropriate antibiotic selection is vital in the treatment of serious community-acquired staphylococcal infections.
