Lambert-Eaton myasthenic syndrome.
Lambert-Eaton myasthenic syndrome (LEMS) is an idiopathic or paraneoplastic syndrome producing antibodies against presynaptic voltage-gated P/Q calcium channels. This decreases calcium entry into the presynaptic terminal, which prevents binding of vesicles to the presynaptic membrane and acetylcholine release. LEMS is most often associated with small cell lung cancer, although idiopathic presen...
متن کاملClassic diseases revisited Lambert-Eaton myasthenic syndrome
The Lambert-Eaton myasthenic syndrome is a neuromuscular disorder characterised by defective neurotransmitter release at autonomic neurones and presynaptic terminals of the neuromuscular junction. It is caused by an IgG autoantibody formed against especially the P/Q type of voltagegated calcium channels (VGCC) which is an essential component of the mechanism of neurotransmitter release. Many pa...
متن کاملLambert-Eaton myasthenic syndrome involving the diaphragm.
Inspiratory muscle function was assessed in a patient with the Lambert-Eaton myasthenic syndrome that developed in association with a bronchogenic carcinoma. Repetitive maximal inspiratory pressure measurements and the electromyographic response to phrenic nerve stimulation established involvement of the inspiratory muscles in general and the diaphragm specifically in this condition.
متن کاملClinical presentation and differential diagnosis of Lambert-Eaton myasthenic syndrome.
Lambert-Eaton myasthenic syndrome (LEMS) is frequently associated with malignancy, especially small cell lung cancer (SCLC). Here, we describe a patient with a 5-year history of cervical myelopathy who presented with recurrent limb weakness of her limbs and complained of recent progressive weakness. Following an examination that included electromyography, a chest CT scan, and a bronchofiberscop...
متن کاملLambert-Eaton myasthenic syndrome: from clinical characteristics to therapeutic strategies.
Lambert-Eaton myasthenic syndrome (LEMS) is a neuromuscular autoimmune disease that has served as a model for autoimmunity and tumour immunology. In LEMS, the characteristic muscle weakness is thought to be caused by pathogenic autoantibodies directed against voltage-gated calcium channels (VGCC) present on the presynaptic nerve terminal. Half of patients with LEMS have an associated tumour, sm...
