MG

OBJECTIVES: To determine the risk of diabetes mellitus (DM) in patients with myasthenia gravis (MG) in a large cohort representing 99% of the Taiwan population. METHODS: Data from the Taiwan National Health Insurance Database were used to conduct retrospective cohort analyses. The study cohort comprised 1520 patients with MG who were four-fold frequency matched to those without MG by age and sex, and assigned the same index year. Cox proportional hazard regression analysis was conducted to estimate the risk of DM...

Thymectomy is a well-established indication for management of myasthenia gravis and it represents the most effective treatment for thymic tumors. The traditional surgical approach is median sternotomy. More recently, different less-invasive surgical approaches for thymectomy have been proposed as an alternative to open surgery. This article discusses the main technical aspects and results of literature.

PURPOSE: To depict the long-term outcome of patients with myasthenia gravis after thymectomy in combination with immunotherapy, and the factors that may potentially affect the outcome. METHODS: The 306 patients with myasthenia gravis who underwent extended thymectomy from January 1984 to December 2011 at Tongji Hospital were retrospectively evaluated. RESULTS: The patients consisted of 174 cases with thymoma and 132 cases without thymoma. Pharmaceutical treatment was tailored for each case during follow-up...

Myasthenia gravis is a prototypical antibody-mediated autoimmune neuromuscular disorder. Treatments have improved over the past 30 years, leading to significantly fewer deaths and better quality of life. Future research should further elucidate its pathogenesis, reveal better ways to diagnose it, and yield new treatments.

This paper provides a thorough overview of the current advances in diagnosis and therapy of myasthenia gravis (MG). Nowadays the term 'myasthenia gravis' includes heterogeneous autoimmune diseases, with a postsynaptic defect of neuromuscular transmission as the common feature. Myasthenia gravis should be classified according to the antibody specificity [acetylcholine, muscle-specific receptor tyrosine kinase (MuSK), low-density lipoprotein receptor-related protein 4 (LRP4), seronegative], thymus histology (thymitis, thymoma, atrophy), age at onset (in children; aged less than or more than 50 years) and type of course (ocular or generalized)...

OBJECTIVE: Thymectomy is a well-defined therapeutic option for patients with myasthenia gravis; however, controversies still exist about the surgical approach, indication, and timing for surgery. We reviewed our experience reporting surgical and neurologic results after robotic thymectomy in patients with myasthenia gravis. METHODS: Between 2002 and 2010, 100 patients (74 female and 26 male; median age, 37 years) underwent left-sided robotic thymectomy using the da Vinci robotic system (Intuitive Surgical, Inc, Sunnyvale, Calif)...

BACKGROUND AND PURPOSE: Several small retrospective studies have observed that patients with a purely ocular manifestation of myasthenia gravis (MG) are significantly less likely to convert to a generalized disease when treated early on with corticosteroids. However, given the limited number of reported patients in the literature these findings still remain controversial. METHODS: In order to increase the number of published cases, we performed a retrospective analysis on 44 patients with newly diagnosed ocular MG who were subsequently either treated with corticosteroids or received no immunosuppressive therapy at all...

Myasthenia gravis (MG) is the most common disorder of the neuromuscular junction (NMJ), with an estimated prevalence between 25 and 142 per million. It characteristically presents with fatigable weakness, often initially involving the ocular muscles and manifesting as intermittent ptosis and diplopia. Ultimately, the disease generalizes in two-thirds of patients, leading to weakness of bulbar, neck, limb, and respiratory muscles. The majority of patients with generalized MG, and roughly half of patients with purely ocular disease, harbor antibodies to skeletal muscle nicotinic acetylcholine receptors...
