myasthenia gravis (mg) is a disorder of the neuromuscular junction. in children, the disease may be congenital or due to an autoimmune process. clinical manifestations may be purely ocular or may include generalized weakness, fatigability, dysphagia, and disorders of speech. in this article, 27 children (14 female, 13 male) were prospectively studied from birth to age fifteen. disease presentat...

Two patients with severe generalised myasthenia gravis of childhood were successfully treated with immunoadsorption plasmapheresis. One patient was a 5 year old girl and the other was a 12 year old girl. A dramatic improvement in bulbar symptoms and generalised muscle weakness was achieved without any side effects. Plasma exchange may also yield clinical improvement for myasthenia gravis, but t...

In recent years, understanding of the pathogenesis and clinical presentation of distinct myasthenia subtypes has increased significantly. This article reviews the clinical manifestations of autoimmune myasthenia gravis (including myasthenia associated with anti-muscle-specific kinase antibodies), ocular myasthenia, and antibody negative myasthenia. The following treatments are examined: choline...

Congenital myasthenia gravis is caused by genetic mutations affecting neuromuscular transmission, characterized by muscle weakness usually starting in childhood. A two and a half years old male child presented with bilateral ptosis and hoarseness of voice. The symptoms progressed giving the clinical impression of congenital myasthenia gravis. A series of tests were done including Ice Pack Test,...

Juvenile myasthenia gravis is a rare disorder acquired in childhood, representing 10% to 15% of all cases of myasthenia gravis. Like the adult form, it is generally characterized by an autoimmune attack on acetylcholine receptors at the neuromuscular junction. Most patients present with ptosis, diplopia, and fatigability. More advanced cases may also have bulbar problems and limb weakness. Left...

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...
