title: [Myasthenia gravis: diagnosis and treatment].
abstract: BACKGROUND
  Myasthenia gravis is an autoimmune disorder characterized by fluctuating muscle weakness and fatigue of different muscle groups. Myasthenia gravis may affect persons of all ages, but especially women aged 20 to 40 years.
  
  
  CONCLUSIONS
  The ocular, facial and bulbar muscles are most often involved in this disease. The muscle weakness of patients with myasthenia gravis becomes worse with intercurrent episodes of infection, fever and physical or emotional exhaustion. Respiratory infection (bacterial or viral) is the most frequent trigger factor. The presence of antibodies to acetylcholine receptors in a patient with the clinical features of myasthenia gravis, confirms the diagnosis. Treatment is controversial. Each patient therefore has to be treated individually, as no single treatment is suitable for all patients. Treatment may include anticholinesterase drugs, corticosteroids, plasmapheresis, immunoglobulin, immunosuppressive drugs and thymectomy.
