title: Distal spinal muscular atrophy of upper limb (Hirayama disease) associated with high serum lead levels.
abstract: Hirayama disease causes unilateral or asymmetrical bilateral distal weakness and atrophy of upper limbs. We report a 6 1/2-year-old female with Hirayama disease and associated high serum lead levels. This report highlights the occurrence of this condition in younger children and the need to further study the role of lead in its pathophysiology.
