Premature craniosynostosis-a complication of thyroid replacement therapy.

Three hypothyroid children with premature craniosynostosis are presented, who have been treated intensively with 1-thyroxine from early infancy. It is postulated that the craniosynostosis is the result of iatrogenic hyperthyroidism during a critical period of skull growth. Various regimens of treatment for hypothyroidism are discussed with recommendations for avoiding this potentially hazardous complication of therapy.

Craniosynostosis, midfacial hypoplasia and foot abnormalities: an autosomal dominant phenotype in a large Amish kindred.

An unusual spectrum of craniofacial and foot abnormalities has been detected within a large midwestern Amish kindred. Enlarged great toes and craniofacial abnormalities suggested Pfeiffer acrocephalosynadactyly type V; however, thumb abnormalities were not present. Eighty-eight affected individuals were observed and another 50 were reliably reported to be affected. An autosomal dominant inheritance pattern was observed associated with variable expressivity. All affected individuals had some clinical or radiologic abnormality of the feet. The phenotypic expression was so variable that the entire spectrum of dominantly inherited craniofacial dysotoses-acrocephalosyndactylys (except the typical Apert syndrome) was seen within this kindred.

A heritable syndrome of craniosynostosis, short thin hair, dental abnormalities, and short limbs: cranioectodermal dysplasia.

Five children are reported with dolichocephaly (with sagittal suture synostosis in three), sparse, slow-growing, fine hair, epicanthal folds, hypodontia and/or microdontia, short span, brachydactyly and brachypodia, and narrow thoraces. Radiologic abnormalities were noted chiefly in the skull, chest, and limbs. Intelligence was normal. The pattern of inheritance is compatible with an autosomal recessive trait.

Dominant inheritance of cerebral gigantism.

Cerebral gigantism is a syndrome consisting of characteristic dysmorphic features, accelerated growth in early childhood, and variable degrees of mental retardation. Its etiology and pathogenesis have not been defined. Three families are presented with multiple affected members. The vertical transmission of the trait and equal expression in both sexes in these families indicates a genetic etiology with a dominant pattern of inheritance, probably autosomal. As in previously reported cases, extensive endocrine evaluation failed to define the pathogenesis of the accelerated growth present in this disorder.

Subtotal neonatal calvariectomy for severe craniosynostosis.

This report sets forth an example of a new mode of management of severe craniosynostosis in the neonate: subtotal calvariectomy. An infant with synostosis of sagittal, coronal, and lambdoidal sutures who had signs of increased intracranial pressure with impending neurologic complications was operated on at 13 days of age. Wide excision of the bony calvarium from the underlying dura was accomplished from the supraorbital ridge to near the foramen magnum; the entire area of the coronal sutures was included. Regeneration of the calvarium occurred over two to 12 weeks and was accompanied by the presence of "sutures" in a usual location. These procedures have allowed for normal brain growth without reoperation up to the current age of two years. Neurologic and intellectual performance has been satisfactory, and cosmetic results appear to be preferable to those obtained by more limited surgery. The observations suggest that this approach may permit better craniofacila growth by minimizing secondary deformities in growth of the cranial base.

Saethre-Chotzen syndrome: a broad and variable pattern of skeletal malformations.

A family is described in which 15 persons in five generations are affected with a complex of skeletal malformations which variably includes peculiar asymmetric facies, delayed closure of large fontanels, brachycephaly, acrocephaly, brachydactyly, cutaneous syndactyly, broad great toes, and mild shortness of stature. Although craniosynostosis is either lacking or relatively mild in the members of this family, their features are otherwise strikingly similar to those of patients with the Saethre-Chotzen syndrome. We believe the findings in this family indicate that the Saethre-Chotzen syndrome comprises a broad pattern of carniofacial and other skeletal malformations in which craniosynostosis may sometimes occur.

Premature craniosynostosis: A common complication of juvenile thyrotoxicosis.

Cranial vault suture opacification (apparent closure) and bone age were evaluated roentgenographically in ten children with thyrotoxicosis. The bone age was advanced greater than 2 SD in only one. In comparison to 96 control children of similar age, craniosynostosis was present in each of the patients with thyrotoxicosis. Children with advanced bone age, nine due to virilizing adrenal hyperplasia and three with precocious puberty, had normal radiographic patterns of cranial suture closure. Thyrotoxic premature craniosynostosis did not interfere with continued head circumference growth nor did it result in clinical or radiographic evidence of increased intracranial pressure. We conclude that premature craniosynostosis appears to be a common feature of juvenile thyrotoxicosis. Investigation of the possible long-term adverse effects of this entity on central nervous system function is advocated.
