Lambert-Eaton myasthenic syndrome (LEMS) is a rare neuromuscular junction (NMJ) disorder which is categorised as either paraneoplastic or primary autoimmune. In both forms, auto-antibodies target voltage-gated calcium channels at the presynaptic level of the NMJ. Paraneoplastic LEMS is most commonly associated with small cell lung cancer (SCLC), but it can also be caused by other malignancies.

Background And Objectives: This study aimed to describe the clinical and prognostic characteristics of antibody-positive paraneoplastic neurological syndrome (PNS) associated with immune checkpoint inhibitors (ICIs).
Methods: We conducted a systematic review of relevant publications in PubMed and Embase from inception to December 2023. Patients with positive anti-neuronal antibodies who had a definite, probable, or possible diagnosis of PNS based on the 2021 PNS-Care Score criteria were included.

Background: Epidemiological frequency measures serve as reference point for patients, clinicians, researchers, and policymakers. Previously, we published a comprehensive review of the literature with prevalence and incidence rates for thirty neuromuscular disorders frequently encountered in the neuromuscular clinic. No meta-analyses were available at the time.

Lambert-Eaton myasthenic syndrome (LEMS) is a paraneoplastic or autoimmune neuromuscular disorder that typically presents with limb weakness or autonomic dysfunction. Here, we report a rare case of LEMS with acute type 2 respiratory failure as the initial symptom. A 79-year-old woman was admitted with acute disturbance of consciousness and type 2 respiratory failure.

Primary Sjögren's syndrome (pSS) and myasthenia gravis (MG) are autoimmune diseases and are rarely reported in coexistence. MG is a chronic autoimmune neuromuscular disease where antibodies bind to acetylcholine receptors or to functionally related molecules in the postsynaptic membrane, weakening the skeletal muscles and causing diplopia, ptosis, and difficulty in breathing and swallowing. In this report, we discuss the case of a 43-year-old female patient who presented with dry eyes, weight loss, fatigue, ptosis, dysarthria, and quadriparesis, which ultimately led to the diagnosis of pSS and MG.
