Mice from eight inbred strains were immunized with acetylcholine receptor (AChR) purified from Torpedo californica. All mice developed high concentrations of serum antibodies (10(-6) M) against the immunogen and approximately 80% possessed antibodies reactive with mouse nicotinic AChR. 33% of the mice immunized (n = 236) developed muscular weakness and flaccid paralysis. Behavioral, electrophys...

BACKGROUND Thymectomy has been a mainstay in the treatment of myasthenia gravis, but there is no conclusive evidence of its benefit. We conducted a multicenter, randomized trial comparing thymectomy plus prednisone with prednisone alone. METHODS We compared extended transsternal thymectomy plus alternate-day prednisone with alternate-day prednisone alone. Patients 18 to 65 years of age who ha...

hla-drb1 allele frequencies of 28 myasthenia gravis (mg) patients, residents of southern iranian provinces, were studied using pcr-ssp method. the control group consisted of 100 healthy individuals of the same ethnic group. the allele hla-drb1 * 16 (rr= 2.04, p= 0.028) was found to be significantly increased in mg patients compared to the control group, whereas hladrb1 * 15(rr= 0.17 p= 0.043) a...

facioscapulohumeral muscular dystrophy (fshd) is a common inherited muscular dystrophy presented clinically with slowly progressive weakness and wasting of facial and limb muscles and rare bulbar muscle involvement. we present herein a 70-year-old man who was a known case of fshd with complaint of 15-day history of progressive difficulty in chewing and dysarthria and was found to have myastheni...

A new surgical technique for thymectomy is presented. Three hundred and seventeen patients with myasthenia gravis and 20 with thymomas who had myasthenic symptoms were operated on. The new surgical approach--a small transverse sternotomy--was used in 257 cases (in 240 patients with myasthenia gravis and 17 with thymomas) and conventional median sternotomy in 80. In myasthenic patients small tra...

BACKGROUND Celiac disease is described in association with several autoimmune diseases, but rarely with myasthenia gravis. CASE REPORT We describe the case of a 31-year-old white woman with celiac disease who presented manifestations related to a hyperactive immune system, including macroamylasemia, false-positive anti-HCV, positive antinuclear antibody, and Raynaud's phenomenon. The introduc...

Myasthenia gravis is an autoimmune disease that is characterised by muscle weakness and fatigue, is B-cell mediated, and is associated with antibodies directed against the acetylcholine receptor, muscle-specific kinase (MUSK), lipoprotein-related protein 4 (LRP4), or agrin in the postsynaptic membrane at the neuromuscular junction. Patients with myasthenia gravis should be classified into subgr...

there are many tests for diagnosis of myasthenia gravis including tensilon test and ice test.to compare the ice test with tensilon test in sub jects with myasthenic and nonmyasthenic ptosis a process research study was designed. this study was performed in patients complaining of acquired ptosis in the neuro-ophthalmology center of farabi hospital. all 156 patients were tested with ice pack and...

Purpose: We conducted this study to retrospectively analyze the clinical effects of surgical resection for patients with myasthenia gravis (MG) complicated with thymoma. Methods: 162 patients with myasthenia gravis complicated with thymoma, that were admitted to our hospital and underwent surgical disease resection from Nov. 1993 to Nov. 2015, were selected for this study. Analyzed were the pat...

Introduction Patients with myasthenia crisis can develop Takotsubo stress cardiomyopathy (SC) due to emotional or physical stress and high level of circulating catecholamines. We report a patient who developed recurrent Takotsubo cardiomyopathy during myasthenia crisis. Coexisting autoimmune disorders known to precipitate stress cardiomyopathy like Grave's disease need to be evaluated. Case R...
