Amyotonia congenita.

A case study of an infant with the disease Amyotonia Congenita. General introduction to the condition; pathology; histology; case illustration of an infant at ten months; appearance; findings on examination; progress.

Segment 1 The condition Amyotonia Congenita is described by the intertitles, including the symptoms and pathologic findings. A series of magnifications of the muscles is shown, showing atrophy and increase of connective and areolar tissue. The increase of sarcolemna-nuclei and connective tissue are pointed out. A case study of a ten-monnth-old baby girl is introduced, and she is seen lying on a table. She has never been able to sit up and moves her arms very little, with no motion in the legs. An intertitle says that although her face is somewhat expressionless, her mentality is normal. A doctor moves the baby's limbs, and intertitles explain that although the muscles show no wasting, there is a loss of power.

Her feet are characteristic of the disease, being long and narrow and lacking normal skin furrows. The doctor tickles the feet but there is no reaction. The doctor also taps her knees to test her reflexes, but her legs do not kick. She is shown unable to sit up or support her head. The final intertitles explain that there is no specific treatment, and the prognosis is that there may be some improvement but most children with the disease are ultimately unable to walk, sit up or stand, and usually succumb to some intercurrent infection.
