A family is reported in which myasthenia gravis and thyroid disease occur over three generations. The grandmother and granddaughter have ocular myasthenia and an aunt in the second generation had generalised myasthenia gravis with a thymoma. The pattern of histocompatibility antigens (HLA) haplotypes, anti-AChR antibodies, anti-striate muscle antibodies and thyroid disease is described. The hap...

Intestinal pseudo-obstruction is considered to be one of the most frequent gastrointestinal manifestations of myasthenia gravis, accompanied by the presence of neoplasia of the thymus gland in the vast majority of the cases presented in the international literature. Despite the fact that myasthenia gravis has been implicated to be the cause of recurrent episodes of intestinal pseudo-obstruction...

Neuromuscular junctions from patients with early onset and chronic myasthenia gravis were examined by electrophysiological and ultrastructural techniques. Acetylcholine (AcCh) sensitivities were reduced by 34-63% in early onset myasthenia and 60-80% in chronic myasthenia. Ultrastructural analysis revealed that virtually all junctional folds of the early onset patients were intact but that the A...

Myasthenia gravis is an autoimmune neuromuscular disorder characterized by skeletal muscle involvement, causing muscle weakness and fatigue. The prevalence of the disease is approximately 1:7500 with a maximal prevalence during the second and third decade in women and the fifth and sixth decade in men, although it may appear at any age. The disease has a slight female preponderance, with a sex ...

In 1936 I presented a report of four cases of myasthenia gravis, in two of which gross thymic lesions were found. At that time in a review of the literature only 80 cases of myasthenia gravis which had come to autopsy were found, and among these were 35 in which a lesion of the thymus constituted a prominent anatomic feature. I t appears that progress toward a more exact understanding of myasth...

From the present study, and from reports in the literature, two forms of childhood myasthenia emerge. There is an early-onset form (with onset of symptoms under 2 years of age) where the illness is milder but more persistent, and where there is frequent occurrence of myasthenia in sibs. Such cases are likely to be inherited as an autosomal recessive, although it is possible that they represent ...

Familial infantile myasthenia is an autosomal recessive disorder, recently classified as congenital myasthenic syndrome type Ia. Onset of symptoms is at birth to early childhood with significant myasthenic weakness and possible respiratory distress, followed later in life by symptoms of mild to moderate myasthenia. Thirty-six patients of 12 families, seven of them consanguineous, were used to m...

INTRODUCTION Myasthenia gravis is an autoimmune disease characterized by fluctuating muscle weakness. It is often associated with other autoimmune disorders, such as thyroid disease, rheumatoid arthritis, systemic lupus erythematosus, and antiphospholipid syndrome. Many aspects of autoimmune diseases are not completely understood, particularly when they occur in association, which suggests a co...

INTRODUCTION Myasthenia gravis (MG) is an autoimmune disease characterized by weakness and fluctuating pathological tiredness of cross-striped muscle with improvement after rest. GOAL To compare the outcomes of treatment in myasthenic crisis therapy and conventional therapy with high doses of human immunoglobulin. Epidemiological research, mainly retrospective, partly prospective, descriptive...

THE ASSOCIATION of myasthenia gravis with Hashimoto's disease and pernicious anaemia was described in a patient by Singer & Sahay (1966). Another patient with myasthenia gravis and pernicious anaemia who showed post-mortem evidence of Hashimoto's disease was reported by Simpson (1964). A further case history in which the patient had overt manifestations of these three conditions is described here.
