A 57-year-old woman presented with a 4-years history of progressive weakness, distal muscular atrophy and myotonia in left hand (Figure 1). Her electromyography had a myotonic pattern. Patient was first diagnosed as paraneoplasic limbic encephalitis based on her brain MRI (Figure 2). Diagnosis was genetically confirmed for myotonic dystrophy type 1 (DM1). DM1 or Steinert’s disease is an autosom...

Non-dystrophic myotonias (NDM) are rare muscle disorders caused by mutations in skeletal voltage-gated channels leading to delayed relaxation after voluntary contraction. They subdivided into sodium channelopathies, when the mutation is SCN4A gene, and chloride CLCN1 gene. Symptoms, which may differ according subtype, exacerbating factors, over disease course, can include stiffness, pain, fatig...

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...

Myasthenia gravis and myotonic dystrophy do not usually coexist; however, we present a rare case where both conditions coexisted. Herein, we describe a 34-year-old woman who presented with symptoms of myasthenia gravis with coexisting myotonic dystrophy. She complained of limb weakness, difficulty in chewing and swallowing, and ptosis. She also had myotonia. The patient’s brother also had simil...

He also has history of inability to walk fast or run and delayed opening of left eye after forceful closure of bot...

The disorder of skeletal muscle known as myotonia has repeatedly attracted the interest of clinical neurophysiologists. The condition is characterized by a prolonged contraction ofmuscle fibres following voluntary exertion; alternatively it may be induced by direct or indirect electrical stimulation of muscle or by mechanical percussion of the muscle belly. The condition may be an accompanying ...
