Seronegative Autoimmune Limbic Encephalitis: A Case Report.

Autoimmune encephalitis (AE) is an immune-mediated disorder of the central nervous system (CNS). Its definitive diagnosis relies on the identification of a specific antibody. Autoimmune limbic encephalitis (LE) is a subset of AE characterized by inflammation of the limbic cerebral cortex.

Efficacy and Safety of Rituximab in Central Nervous System Demyelinating Disorders.

Background: Rituximab, an anti-CD20 monoclonal antibody, has been used worldwide as an off-label therapy in patients with multiple sclerosis (MS) and neuromyelitis optica spectrum disorders (NMOSD).

Objective: The aim of the present study was to evaluate the efficacy and safety of rituximab in central nervous system demyelinating disorders in the Indian context.

Methods: We conducted a retrospective analysis of patients with MS, NMOSD, and myelin oligodendrocyte glycoprotein antibody disease (MOGAD) who were treated with rituximab at a single tertiary care centre in Mumbai.

Epidemiology and treatment of Parkinson's disease in India.

Parkinson's disease (PD) has a low prevalence in India except in the small Parsi community where Bharucha et al. found a high prevalence. Although early onset PD and familial cases have been described from India, no genetic mutations have as yet been identified.

Limited sequence divergence of HTLV-I of Indian HAM/TSP patients from a prototype Japanese isolate.

Nucleotide sequences of two HTLV-I proviruses isolated from Indian patients with HAM/TSP were analyzed. The sequence data of the env, pX, and LTR regions showed 98-99% homologies with the prototype HTLV-I, ATK-1, isolated from a Japanese ATL patient, indicating that HTLV-I isolates in India and Japan are similar, with minor variations. However, certain small sequences of noncoding regions in the pX and LTR showed differences of 6.
