Neurotropism and infiltration by Mycobacterium leprae of peripheral nerves causing neuropathy are well established, but reports central nervous system (CNS) damage exceptional. We report CNS magnetic resonance imaging (MRI) abnormalities the brain spinal cord as lesions in nerve roots plexus leprosy patients. Eight patients aged between 17 41 years underwent detailed clinical, histopathological, MRI evaluation. All had prominent sensory–motor deficits with hypopigmented hypo/anesthetic skin...

Resistance to anti-leprosy drugs is on the rise. Several studies have documented resistance rifampicin, dapsone, and ofloxacin in patients with leprosy. We looked for point mutations within folP1, rpoB, gyrA gene regions of Mycobacterium leprae genome predominantly neural form DNA samples from 77 nerve tissue were polymerase chain reaction (PCR)-amplified M sequenced drug resistance-determining genes gyrA. The mean age at presentation onset was 38.2 ± 13.4 (range 14-71) years 34.9 12.6...

Congenital myasthenic syndromes (CMS) are a clinically and genetically heterogeneous group of disorders caused by mutations which lead to impaired neuromuscular transmission. SLC25A1 encodes mitochondrial citrate carrier, associated mainly with the severe neurometabolic disease combined D-2- L-2-hydroxyglutaric aciduria (D/L-2-HGA). We previously reported single family homozygous missense variant in phenotype restricted relatively mild CMS intellectual disability, but date no additional...

To elucidate the spectrum of findings on neuroimaging in leprosy with special reference to magnetic resonance imaging (MRI). We retrospectively reviewed MRI thirty-two patients where dedicated plexus, brain and spine had been performed. Twenty-two positive imaging. Six showed involvement peripheral nerves as thickening formation micro or macroabscesses. The brachial plexus hyperintensity ten patients, associated lumbosacral one patient. Four spinal cord discrete T2 hyperintense lesions...

Motor neuron disease (MND) is a progressive neurodegenerative disease. Ideal management plan in MND includes palliative care initiated from the time of diagnosis. At present, most conditions are cared for at home. Neuropalliative an emerging concept India and social workers integral team members this process. The primary aims study were to explore (a) caregivers' experiences end-of-life stage, (b) sources support individuals their caregivers with stage. In-depth interviews conducted seven...

Identification of Mycobacterium leprae DNA by polymerase chain reaction (PCR) is a reliable and an affordable method to confirm leprosy. from 87 nerve samples (61 paraffin blocks 26 fresh samples) was extracted. amplified PCR 80/87 (92%) specimens. Patients were seen over period 11 years (2007-2019), leprosy diagnosed based on clinical characteristic histopathology findings. The diagnostic possibilities as follows: leprous neuropathy in 73/80 (91.3%), mononeuritis multiplex unknown etiology...

Large vessel occlusion stroke contributes to disability and mortality out of proportion its incidence. Over time it was noted that intravenous thrombolysis alone not sufficient for this type. Slowly, endovascular approach mechanical clot retrieval have come be the biggest advances in field neurology as well modern medicine. Although careful selection patients is needed standardized by landmark trials. At same time, thrombectomy now being studied excluded previous trials seemingly coming...
