Myasthenia gravis: An embryologic and phylogenetic perspective.

Myasthenia gravis is a rare disease with unique clinical features. These include (1) progressive fatigue on exertion, most evident clinically in the muscles of the head and neck (2) a definite relationship of the disease to the thyroid, parathyroid and thymus glands. A hypothesis is advanced with correlates these facts on the basis of a common embryologic origin of these glands and the branchial arch muscles. A corollary is that the muscles of the head and neck differ from the somatic musculature in some as-yet-unidentified manner, for example, pharmacologically. A plea is made for comparative studies between the two.

Painful tonic spasms caused by putaminal infarction.

Lacunar infarcts in the basal ganglia are known to cause various movement disorders, such as chorea, focal dystonia, and hemichorea-hemiballismus. We report here a case of putaminal lacunar infarction which presented with "painful tonic spasms" of the contralateral limbs. This consisted of paroxysmal brief, painful, flexor contractures of the upper, and occasionally the lower limb. These were not focal seizures but were controlled with carbamazepine, which has been used for the "painful tonic spasms" well-associated with multiple sclerosis. The putaminal infarct we describe is probably related to a lupus anticoagulant and systemic lupus erythematosus.
