| muscle, central core disease of | One of the conditions that produces 'floppy baby' syndrome. Ccd causes hypotonia (inadequately toned muscles characterised by floppiness) in the newborn baby, slowly progressive muscle weakness, and muscle cramps after exercise. Muscle biopsy shows a key diagnostic finding (absent mitochondria in the centre of many type i muscle fibres). Ccd is inherited as a dominant trait. The ccd gene is on chromosome 19 (and involves ryanodine receptor-1). (12 Dec 1998) |
| muscle relaxants, central | A heterogeneous group of drugs used to produce muscle relaxation, excepting the neuromuscular blocking agents. They have their primary clinical and therapeutic uses in the treatment of muscle spasm and immobility associated with strains, sprains, and injuries of the back and, to a lesser degree, injuries to the neck. They have been used also for the treatment of a variety of clinical conditions that have in common only the presence of skeletal muscle hyperactivity, for example, the muscle spasms that can occur in multiple sclerosis. (12 Dec 1998) |
| myelinolysis, central pontine | A form of massive demyelination of the pons occurring in malnutrition and alcoholism. The remarkable unsystematic dissolution of the sheaths of medullated fibres is its most certain feature. The lesion varies from only a few millimeters in diameter to almost the entire pons. The basic pathology is the destruction of the medullated sheaths throughout the lesions with relative sparing of the axis cylinders and intactness of the nerve cells of the pontine nuclei. Pathologically it is easily differentiated from infarction and the inflammatory demyelinations of multiple sclerosis and postinfectious encephalomyelitis. There does not appear to be a genetic, sex, or age factor. It is often, however, associated with some other serious disease, particularly chronic alcoholism.
