Hydrocephalus-stenosis of the acqueduct of Sylvius sequence (HSAS) is characterized by hydrocephalus, macrocephaly, adducted thumbs, spasticity, agenesis of the corpus callosum and mental retardation. X-linked hydrocephalus is known to be due to mutations in the gene coding for the neural cell adhesion molecule L1 (L1-CAM) and diagnosis is made by identification of a mutation in the L1-CAM gene. Prenatal diagnosis of HSAS is usually suggested on ultrasound examination showing hydrocephalus in a male fetus associated with bilateral adducted thumbs. Mutation screening of the L1-CAM gene is indicated when neuropathological examination shows hypoplasia of the corticospinal tract associated with aqueductal stenosis. We report here two cases of HSAS diagnosed within the same family by ultrasound examination in the first trimester of pregnancy when bilateral adducted thumbs were the only early ultrasound marker.

Muscle biopsy was examined in 20 children with cerebral palsy, using immunohistochemical methods for marker of denervation neural cell adhesion molecules (N-CAM) in addition to standard techniques. Histological and histochemical study showed mild myopathic changes, type 1 predominance, and type 1 and type 2 hypotrophy, in accord with previous observations. Immunohistochemical study showed N-CAM expression in most biopsies (15/20), usually in scattered fibers, whereas in four patients aged less than 6 years it was expressed in grouped fibers. Our study supports the hypothesis of motor unit remodeling as a consequence of spasticity, especially in early phases of the disease.
