[Duchenne muscular dystrophy. Review of 37 cases].
Clinical, analytical, histological and electromyographical findings observed in 37 males with Duchenne's Muscular Dystrophy are presented. Ages were between 14 months and 10 years. Follow-up of 18 patients was made. Motor development retardation is very often the first sign of the disease. 32% of the children did not get the sitting position before 8 months old. 86% walked after 14 months. Clinical alterations are similar to that reported in the literature. Serum muscular enzymes levels don't decrease with age during the first ten years of life, and they aren't in proportion with the severity of clinical disturbances. The most frequent findings in EMG were increase of polyphasia and presence of late components in Motor Unit Potentials (MUP). Decrease of duration of MUP was found only in 50% of studied children. Mothers and other females belonging to families of 17 children were studied; EMG alterations in 97% of females studied were observed. Healthy people controls with EMG were not made. Analytical and EMG findings in these relatives are commented.
