We report a family of a brother and sister of myotonia congenita, conforming to autosomal recessive transmission (Becker's variety). To the best of our knowledge, no account of a family of autosomal recessive myotonia (Becker's disease), has earlier been reported from India.

Myotonia congenita is a hereditary muscle disorder caused by mutations in the human voltage-gated chloride (Cl(-)) channel CLC-1. Myotonia congenita can be inherited in an autosomal recessive (Becker type) or dominant (Thomsen type) fashion. One hypothesis for myotonia congenita is that the inheritance pattern of the disease is determined by the functional consequence of the mutation on the gat...

Myotonia congenita is a rare disease of skeletal muscle characterized by painless myotonia, generalized muscular hypertrophy and a non-progressive course. We report a 10-year-old girl with myotonia, "Herculean appearance" and electromyographic confirmation of myotonic discharges. There was a dramatic response to carbamazepine. The aim of this report is to make the readers aware of this entity w...

1. The objective of the study was to determine the effect of temperature reduction on the response of rat skeletal muscles to myotonia-inducing agents. 2. A model myotonia was induced in the muscles in vitro, using either the chloride channel blocker anthracene-9-carboxylic acid or chloride-free Krebs solution. This model is similar in its characteristics to the myotonia which occurs in autosom...

We report a 4-generation Turkish family with 10 affected members presenting with myotonia and potassium- and exercise-induced paralytic attacks. The clinical presentation was neither typical for the chloride channel myotonias Thomsen and Becker nor for the separate sodium channel myotonia entities potassium-aggravated myotonia, paramyotonia congenita, and hyperkalemic periodic paralysis. It is ...

Virgin's role in the story is that of a mother who uses medicine to treat her child,28 her selection of a remedy recommended by the most prominent medical authorities could scarcely have been more appropriate. The cure would still have been considered a miracle, although based on medical principles. Moreover, by using this device, Chaucer would have appealed to the intellectual capacities of hi...

A 21 year old right handed male resident of Bihar presented with 4 years history of gradual onset progressive st i f fness in both thighs and calves which improves on continued activity along with hypertrophy of muscles of all the limbs and dimpling on hitting over thigh and hands. He also has history of inability to walk fast or run and delayed opening of left eye after forceful closure of bot...
